Detailed ways

Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application and cannot be understood as limiting the present application.

At present, mainstream LCD screens have black borders of a certain width. The black borders are formed during the manufacturing process of the LCD screen. The main reason for the black borders is that the LCD screen is composed of a dot matrix. These dot matrices are composed of dots integrated on the panel. The wires are connected to the external control circuit, so there is a wiring area for integrated circuits at the edge of the screen. This wiring area cannot be removed, and part of the black border is composed of this wiring area. Secondly, the black borders can prevent light leakage from the screen and block the light from the backlight. If there are no black borders at the edge of the screen, an obvious halo will be seen at the edge of the screen. In addition, part of the panel edge needs to be occupied during liquid crystal packaging, and the sealing structure is also one of the reasons for the formation of black edges. To sum up, on the current mainstream LCD screens, the black edges on the edges of the screen cannot be completely removed.

Related technologies improve screen black edges through glass borderless, frame structure stacking optimization, display module edge structure optimization, curved screens, edge optical frame reduction and other solutions. The specific plans are as follows:

(1) Glass frameless: The cover glass completely covers the screen and frame, and the black edges and frames of the screen are covered under the glass cover. However, the display area when the screen is on is smaller than the area of the glass cover, and there are still black borders, which is not a true narrow border or borderless.

(2) Frame structure stacking optimization: By optimizing the frame structure stacking, the black edges of the screen are hidden within the borders, achieving a visual absence of black edges. In this type of solution, the border needs to cover the black edges of the screen, which is often wider and has poor visual effects.

(3) Display module edge structure optimization: During the display panel manufacturing process, the width of the black edges at the edge of the display area is reduced by adjusting the packaging structure, optimizing the wiring design, etc. However, this type of solution can only reduce the width of the black edges to a limited extent, but cannot completely eliminate them.

(4) Curved screen: Taking advantage of the flexible and bendable characteristics of the curved screen, the edge of the screen is designed to be bent or bent at a large angle to achieve a borderless effect. Such solutions require the use of high-cost flexible display technology, and because the screen is curved, the images displayed at the edges are also curved, affecting the use of some scenes. In addition, the current mainstream flexible display technology can only bend two sides, and it is difficult to bend the top, bottom, left, and right sides at the same time, so it is impossible to achieve complete bezel-free all around.

(5) Edge optical frame reduction: Use optical effects to visually reduce or completely eliminate borders and screen black edges. For example, the refraction effect at the edge of the glass cover is used to visually reduce the black edges (similar to the lens principle). However, this method can only reduce but not completely eliminate the black edges, and there is aberration. Alternatively, a Fresnel lens can be used to enlarge the screen display area so that the black edges of the screen are hidden under the Fresnel lens. However, this method has a jagged structure that is not conducive to screen display in appearance.

In view of this, after conducting a lot of research, the inventor proposed an optical fiber panel, which includes multiple optical fibers. The multiple optical fibers are arranged to form an incident part, an intermediate part and an exit part. Through the optical fiber panel, the image emitted from the display screen can be The light is guided from the incident part to the exit part. Since the exit part protrudes outside the orthographic projection range of the incident part, the black border of the display screen can be hidden under the exit part, increasing the screen-to-body ratio and achieving a narrow frame or completely borderless effect. ; At the same time, the light propagation directions of the multiple incident sections in the incident part and the light propagation directions of the multiple exit sections in the exit part are the same, so that the propagation direction of the image light emitted from the display screen is not changed and the display effect is not affected. Furthermore, the inventor also proposed screens and electronic devices including the optical fiber panel.

Compared with the narrow bezel solution for curved screens, the cost of fiber optic panels is relatively low, and the edge display screen will not be deformed. Compared with the Fresnel lens solution, the appearance of the fiber optic panel does not have a sawtooth structure, making it more suitable for screen displays. Secondly, fiber optic panels do not have various aberrations caused by refraction or diffraction. In addition, fiber optic panels made of glass can be chemically strengthened to increase their strength, thereby replacing ordinary glass covers. Fresnel lenses made of glass are extremely difficult to process, so Fresnel lenses are often made of plastic, and the naturally existing sawtooth structure on the surface of the Fresnel lens will greatly reduce the strength of the panel. All in all, fiber optic panels have obvious advantages in terms of appearance, display effect, material strength, and ease of processing.

In order to enable those in the technical field to better understand the solution of the present application, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of this application.

Please refer to Figures 1 and 2 together. The embodiment of the present application provides an optical fiber panel 100, which includes a plurality of optical fibers 110. Each optical fiber 110 includes an incident section 111, a middle section 112 and a In the exit section 113, the entrance sections 111 of the plurality of optical fibers 110 are connected to each other to form the entrance section 120, the intermediate sections 112 of the plurality of optical fibers 110 are connected to each other to form the intermediate section 130, and the exit sections 113 of the plurality of optical fibers 110 are connected to each other to form the exit section 140. The portion 140 at least partially protrudes outside the orthographic projection range of the incident portion 120, that is, the projection of the exit portion 140 along the thickness direction completely covers the projection of the incident portion 120 along the thickness direction,

The light propagation directions of each exit section 113 and each incident section 111 are the same. In one embodiment, the light propagation directions of the multiple incident sections 111 in the incident part 120 and the light propagation directions of the multiple exit sections 113 in the exit part 140 are the same as each other, that is, the light propagation directions of all the incident sections 111 and all the exit sections 111 are the same. The light propagation directions of the segments 113 are the same as each other. The orthographic projection direction of the incident part 120 is the same as the light propagation direction of the outgoing section 113 and the incident section 111 .

The optical fiber 110 uses total reflection of light to guide light, and the light propagation direction of the optical fiber 110 may refer to the axial direction of the optical fiber 110 . The light propagation directions of all the exit sections 113 and the incident section 111 are the same, that is, the axial directions of all the exit sections 113 and the incident section 111 are the same.

As shown in FIG. 3 , the optical fiber panel 100 is used to be assembled on the display screen 210 . The display screen 210 may include a display area 211 and a non-display area 212 (ie, black border) surrounding the display area 211 . The incident part 120 of the optical fiber panel 100 faces the display area 211 of the display screen 210, and the image light emitted from the display screen 210 can be guided from the incident part 120 to the middle part 130 and then emitted through the exit part 140 to form an image display; because the exit part 140 is convex Out of the incident part 120, the black border of the display screen 210 can be hidden under the emission part 140 (see Figure 7 for details), thereby increasing the screen-to-body ratio and achieving a narrow frame or completely borderless effect; at the same time, the black border in the incident part 120 The light propagation directions of the multiple incident sections 111 and the light propagation directions of the multiple exit sections 113 in the exit section 140 are the same, so that the propagation direction of the image light emitted from the display screen 210 is not changed and the display effect is not affected.

In this embodiment, the optical fiber 110 may be made of a transparent glass material, a transparent ceramic material, a transparent single crystal material, a transparent plastic material, or a composite material composed of two or more of the above materials.

Please refer to FIGS. 1 and 4 together. The optical fiber 110 may include a core 115 and a cladding 116 covering the core 115. Light is transmitted in the core 115. In the process of making the optical fiber panel 100, a large number of optical fiber 110 arrays can be arranged first to form an optical fiber panel preform. After the optical fiber panel preform is softened at high temperature, under the action of gravity or external force, the fiber core 115 and the cladding 116 are in equal proportions. The diameter of the optical fiber 110 is reduced to form an incident part 120 , an intermediate part 130 and an exit part 140 with different widths.

The number of optical fibers 110 can be determined according to the size and pixel size of the display screen 210 , as long as the optical fiber panel 100 can cover the display area 211 and at least part of the non-display area 212 of the display screen 210 .

As an implementation manner, as shown in Figure 4, the number of optical fibers 110 is the same as the number of pixels 213 of the display screen 210, and the incident section 111 of each optical fiber 110 is set corresponding to one pixel 213 of the display screen 210 to ensure that the optical fiber panel The resolution of 100 is not lower than the resolution of display 210. Alternatively, as shown in FIG. 5 , multiple adjacent pixel points 213 can also correspond to one optical fiber 110 , that is, the optical fibers 110 emitted from multiple pixel points 213 can be simultaneously exported through one optical fiber 110 , thereby reducing the number of optical fibers 110 ,save costs. Alternatively, please refer to FIG. 6 , each pixel point 213 of the display screen 210 can also correspond to multiple optical fibers 110 , that is, the light emitted by one pixel point 213 is exported through multiple adjacent optical fibers 110 . In this case, the optical fiber panel 100 The resolution is larger than the resolution of the display screen 210 and can achieve better display effects.

Still referring to FIGS. 1 and 3 , the incident part 120 , the intermediate part 130 and the emitting part 140 are stacked and arranged in sequence along the thickness direction of the optical fiber panel 100 . The light propagation direction of each emitting section 113 and each incident section 111 is consistent with the direction of light propagation of the optical fiber panel 100 . The thickness direction is the same, that is, the outgoing section 113 and the incident section 111 both extend along the thickness direction of the optical fiber panel 100 .

When assembling the optical fiber panel 100 and the display screen 210, the optical fiber panel 100 is stacked on the display screen 210, and the thickness direction of the optical fiber panel 100 is consistent with the thickness direction of the display screen 210. The image light of the display screen 210 exits along the thickness direction of the display screen 210 and is incident on the incident section 111. Since the light propagation directions of the exit section 113 and the incident section 111 are the same as the thickness direction of the fiber optic panel 100, it is ensured that the image light is still along the thickness direction of the display screen 210. The thickness direction of the display screen 210 is emitted from the exit section 113 without changing the propagation direction of the image light.

The thickness of the incident part 120, the intermediate part 130 and the exit part 140 can be determined according to actual requirements. As an example, the thickness of the incident part 120 is smaller than the thickness of the emission part 140 , the thickness of the emission part 140 is smaller than the thickness of the intermediate part 130 , and the area of the intermediate part 130 gradually increases from the incident part 120 toward the emission part 140 . Thus, the thicknesses of the incident part 120 , the middle part 130 and the exit part 140 can be reasonably distributed to ensure sufficient connection area between the exit sections 113 located on the outer layer and improve the strength of the exit part 140 . The thickness of the middle part 130 is the largest, and the area of the middle part 130 gradually increases from the incident part 120 to the exit part 140, which can play a good transition role and avoid sudden changes in the size of the optical fiber panel 100 and local stress concentration.

The specific shapes of the incident part 120 , the intermediate part 130 and the emission part 140 are determined according to the shape of the display screen 210 , and the shapes of the incident part 120 , the intermediate part 130 and the emission part 140 are adapted to the display screen 210 . As an example, the display area 211 of the display screen 210 is generally rectangular, and the non-display area 212 is generally rectangular frame-shaped. At this time, the incident part 120 and the emission part 140 may both have a rectangular plate structure, and the middle part 130 may have a rectangular platform structure. The surface of the incident part 120 away from the emission part 140 is the incident surface 121. The shape and size of the incident surface 121 are consistent with the display area 211, so that the display content of the display area 211 can be completely derived. The surface of the exit part 140 facing away from the incident part 120 is the exit surface 141. The entire exit surface 141 is the display area of the optical fiber panel 100. The exit part 140 protrudes outside the incident part 120, that is, the exit surface 141 protrudes outside the incident surface 121. .

The outer periphery of the outgoing part 140 at least partially protrudes outside the orthographic projection range of the incident part 120 . For example, the emitting part 140 may protrude out of the incident part 120 along one or both of the length direction and the width direction of the optical fiber panel 100 . The length direction of the optical fiber panel 100 is consistent with the length direction of the display screen 210 , and the width direction of the optical fiber panel 100 is consistent with the width direction of the display screen 210 . For example, one side of the exit part 140 protrudes out of the incident part 120 along the width direction of the optical fiber panel 100 to hide the non-display area 212 on one side of the width direction of the display screen 210 under the exit part 140; or, the exit part 140 The opposite sides protrude from the incident part 120 along the width direction of the optical fiber panel 100 to hide the non-display areas 212 on both sides of the width direction of the display screen 210 under the exit part 140; or, the outer periphery of the exit part 140 protrudes from The outside of the incident part 120 , that is, the outgoing part 140 protrudes out of the incident part 120 along the length and width directions of the optical fiber panel 100 , so as to hide the entire non-display area 212 below the outgoing part 140 .

The width of the outgoing part 140 protruding out of the incident part 120 may be determined according to the width of the non-display area 212 . For example, the width of the emitting part 140 protruding out of the incident part 120 is smaller than the width of the non-display area 212, so as to block part of the non-display area 212 and achieve a narrow-frame display effect. Alternatively, the width of the emitting part 140 protruding from the incident part 120 is greater than or equal to the width of the non-display area 212 to block the entire non-display area 212 to achieve a true borderless display effect.

The incident surface 121 and the emitting surface 141 of the optical fiber panel 100 may be flat surfaces or curved surfaces of any shape. When the incident surface 121 is a plane, the incident surface 121 can fit the display screen 210 to facilitate the assembly between the fiber optic panel 100 and the display screen 210 and improve the assembly stability of the fiber optic panel 100 and the display screen 210 . When the incident surface 121 is a curved surface, there may be a certain gap between the incident surface 121 and the display screen 210. However, as long as the light propagation direction of the incident section 111 is consistent with the thickness direction of the display screen 210, the output of the display screen 210 can be ensured. The direction of the image light is not changed.

In some other embodiments, the longitudinal section of the display screen 210 can also be circular, triangular, trapezoidal, sector-shaped, semicircular or other irregular shapes. In this case, the longitudinal sections of the incident part 120 and the emitting part 140 can be adjusted accordingly. The shapes will not be described one by one here. The longitudinal section of the display screen 210 is perpendicular to the thickness direction of the display screen 210 , and the longitudinal sections of the incident part 120 and the exit part 140 are perpendicular to the thickness direction of the optical fiber panel 100 .

In some embodiments, a compressive stress layer (not shown in the figure) is formed on the surface of the outgoing part 140 away from the incident part 120 . The compressive stress layer can improve the strength of the optical fiber panel 100, and the compressive stress layer can replace the glass cover, making the structure of the optical fiber panel 100 simpler.

In this embodiment, the optical fiber panel 100 can form a compressive stress layer through strengthening. Strengthening measures include but are not limited to physical strengthening, chemical ion exchange strengthening, ion implantation strengthening, etc. In addition, the strength of the plastic material in the optical fiber panel 100 can also be improved through UV curing, thermal curing and other treatments, thereby further improving the strength of the optical fiber panel 100 .

In some embodiments, the fiber optic panel 100 may further include an optical coating (not shown in the figure), and the optical coating is stacked on the surface of the exit part 140 away from the incident part 120 , that is, it is stacked on the exit surface 141 . The optical coating can be an anti-reflection film to increase the optical transmittance of the optical fiber panel 100; the optical coating can also be a wear-resistant film to improve the surface wear resistance of the optical fiber panel 100; the optical coating can also be an anti-fingerprint film to achieve Anti-fingerprint effect on the panel surface; alternatively, the optical coating can have two or more functional properties at the same time. For example, the optical coating can be a wear-resistant anti-reflective coating, or an anti-reflective coating with wear-resistant and anti-fingerprint properties.

In this embodiment, the material of the optical coating may include one or more of silicon oxide, tantalum oxide, titanium oxide, silicon carbide, polytetrafluoroethylene and other organic fluorides. Specifically, it may be based on the functional characteristics of the optical coating. OK, there is no specific limit here.

In some embodiments, the fiber optic panel 100 may also include a transparent conductive film (not shown in the figure). The transparent conductive film can both conduct electricity and have high light transmittance in the visible light range. The transparent conductive film is stacked away from the exit part 140 The surface of the incident part 120 enables the optical fiber panel 100 to have a touch function.

In this embodiment, the transparent conductive film includes but is not limited to ITO (tin-doped indium trioxide), AZO (aluminum-doped zinc oxide), etc. The method of disposing the transparent conductive film on the surface of the optical fiber panel 100 may be coating, printing, evaporation, sputtering, deposition, etc. The specific method may be determined according to actual requirements. It should be noted that in some embodiments, the optical fiber panel 100 includes both an optical coating and a transparent conductive film. The transparent conductive film can be stacked between the optical coating and the exit part 140 to protect the transparent conductive film through the optical coating.

Still referring to FIGS. 1 and 2 , in some embodiments, the relative position of the incident section 111 of the optical fiber 110 in the incident part 120 corresponds to the relative position of the exit section 113 of the optical fiber 110 in the exit part 140 . For example, the incident section 111 of the same optical fiber 110 is the second in the first row of the incident part 120, and the exit section 113 is also the second in the first row of the exit part 140. In one embodiment, the cross-sectional shapes of the incident part 120 and the exit part 140 are exactly the same, and the ratio of the cross-sectional size of the exit part 140 to the cross-sectional size of the incident part 120 is a value λ greater than 1; for example, the incident part 120 The cross-sectional shape of the exit part 140 and the exit part 140 are all rectangular, and the ratio of the cross-sectional circumference of the exit part 140 to the cross-sectional circumference of the incident part 120 is a value λ greater than 1; the entrance section 111 and the exit section 113 of each optical fiber 110 are parallel to each other, And the plane formed by the incident section 111 and the exit section 113 passes through the central axis of the optical fiber panel 100, that is, the central axis of the optical fiber panel 100 is located on the plane formed by the incident section 111 and the exit section 113;

In the plane, the incident section 111 and the exit section 113 are located on the same side of the central axis, and the ratio of the distance between the exit section 113 and the central axis to the distance between the incident section 113 and the central axis is also λ. Therefore, it can be ensured that the pattern displayed on the optical fiber panel 100 is consistent with the pattern displayed on the display screen 210 or is the result of equal-proportion enlargement.

Referring to FIG. 7 , in some embodiments, the relative position of the incident section 111 of the optical fiber 110 in the incident part 120 is different from the relative position of the exit section 113 of the optical fiber 110 in the exit part 140 . For example, for the same optical fiber 110, its entrance section 111 is the second from the left in the first row of the entrance part 120, and its exit section 113 is the second from the right in the penultimate row of the exit part 140, so that the display screen 210 can be The displayed pattern changes. In one embodiment, the cross-sectional shapes of the incident part 120 and the exit part 140 are exactly the same, and the ratio of the cross-sectional size of the exit part 140 to the cross-sectional size of the incident part 120 is a value λ greater than 1; the incident part of each optical fiber 110 The section 111 and the outgoing section 113 are parallel to each other, and the plane formed by the incident section 111 and the outgoing section 113 passes through the central axis of the optical fiber panel 100, that is, the central axis of the optical fiber panel 100 is located on the plane formed by the incident section 111 and the outgoing section 113; in In the plane, the incident section 111 and the emergent section 113 are located on opposite sides of the central axis, and the ratio of the distance between the emergent section 113 and the central axis to the distance between the incident section 113 and the central axis is also λ. As a result, the image displayed on the fiber optic panel 100 can be centrally symmetrical with the image displayed on the display screen 210 , thereby realizing the flip display of the content displayed on the display screen 210 to meet the different needs of users.

In this embodiment, the cross-section of the middle part 130 is roughly hourglass-shaped, and the middle sections 112 of the middle part 130 are staggered with each other, which can improve the connection strength between the middle sections 112 .

Please refer to Figure 8. The embodiment of the present application also provides a screen 200, which includes a display screen 210 and an optical fiber panel 100. The optical fiber panel 100 is stacked on the display screen 210. The display screen 210 includes a display area 211 and a non-display area 212. The incident part 120 of the panel 100 covers the display area 211 , and the emission part 140 at least partially covers the non-display area 212 .

In the screen 200 provided in the embodiment of the present application, the image light emitted from the display screen 210 can be guided from the incident part 120 to the emitting part 140 through the optical fiber panel 100. Since the emitting part 140 at least partially covers the non-display area 212, the display can be The non-display area 212 of the screen 210 is hidden under the exit part 140 to increase the screen-to-body ratio; when the non-display area 212 is located within the orthographic projection range of the exit part 140, the non-display area 212 can be completely hidden under the exit part 140, thereby achieving True borderless display effect. At the same time, the light propagation directions of the multiple incident sections 111 in the incident part 120 and the light propagation directions of the multiple exit sections 113 in the exit part 140 are the same, so that the propagation direction of the image light emitted from the display screen 210 is not changed and the influence is avoided. display effect.

In some embodiments, the screen 200 further includes an annular body 260 with a substantially right-angled trapezoidal cross-section.
