Background technique

"Glare" is an undesirable lighting phenomenon. When the brightness of the light source is extremely high or the brightness difference between the background and the center of the field of view is large, "glare" will occur. The "glare" phenomenon not only affects viewing, but also has adverse effects on vision health. Anti-glare can effectively reduce this effect, so that the viewer can see clearly even in sunlight.

detailed description

In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Example 1:

This embodiment provides an anti-glare structure for a display device, as shown in FIG. Light; the light-absorbing layer 3 located on the outside of the condenser lens through 2 is used to absorb ambient light; wherein, the light-absorbing layer 3 is provided with a light-transmitting hole 4 at a position corresponding to the condenser lens through 2, and the light-transmitting hole 4 is used for absorbing light The projected area of the layer 3 is smaller than or equal to the projected area of the condenser lens 2 on the light-absorbing layer 3, and the converged light is emitted through the light-transmitting hole 4.

In the anti-glare structure of this embodiment, a condenser lens is used to transmit the light emitted by the display device 1 to form concentrated light; the light-absorbing layer 3 is used to absorb ambient light; In this way, when the ambient light irradiates the surface of the light-absorbing layer 3, most of the ambient light is absorbed by the light-absorbing layer 3, and only a very small amount of ambient light can be reflected, which greatly reduces the glare effect of the ambient light. The anti-glare structure of the utility model not only does not reduce the clarity of the picture, but also can greatly improve the contrast of the product under ambient light, and can realize anti-glare in the true sense.

Example 2:

This embodiment provides an anti-glare structure for a display device, as shown in Figure 1 and Figure 2, comprising a plurality of condenser lens lenses 2 arranged at intervals, which are used to be arranged outside the light-emitting surface of the display device 1 so that the display device 1 emits light. The light forms converging light; the light-absorbing layer 3 arranged on the outside of the condenser lens 2 is used to absorb ambient light; wherein, the position of the light-absorbing layer 3 corresponding to the condenser lens 2 is provided with a light-transmitting hole 4, and the light-transmitting hole 4 The projected area of 3 on the light-absorbing layer is less than or equal to the projected area of the light-absorbing layer 3 on the lens of the condenser lens 2, and the converged light is emitted through the light-transmitting hole 4; diffuse reflection is provided outside the light-absorbing layer 3 The layer 6 is used to make the concentrated light form diffuse reflection, wherein the diffuse reflection layer 6 covers the light absorbing layer 3 and is used to protect the light absorbing layer 3 .

That is to say, the light-absorbing layer 3 is covered with a layer of diffuse reflection layer 6, and the diffuse reflection layer 6 has dual functions of protecting the light-absorbing layer 3 and making the concentrated light perform diffuse reflection.

It should be noted that the condensing lens is selected from materials with good light-condensing and light-transmitting effects, and the preferred material is glass. Specifically, existing etching technology can be used to manufacture glass into strip lenses, which are then bonded to the polarizer 15 of the color filter substrate of the display device 1 .

It can be understood that the higher the absorbance of the material of the light absorbing layer 3, the better. Of course, the same material as that of the black matrix 12 can also be used. Forming the light-absorbing layer 3 and forming the light-transmitting holes 4 on the light-absorbing layer 3 can be prepared by coating, exposing and developing processes.

More specifically, when the anti-glare structure of the present embodiment is used, a plurality of condenser lens lenses 2 and each color filter 13 of the color filter substrate are provided in one-to-one correspondence (indicated by RGB in FIG. The sub-pixels are in one-to-one correspondence, so that light a (only representing the direction of light propagation) from the backlight enters the condenser lens corresponding to the sub-pixel after passing through the liquid crystal layer 14 and the color filter 13, and other light rays in the non-display area are Absorbed by the black matrix 12. The light emitted from the sub-pixels is converged by the condenser lens, concentratedly irradiated on the area where the light-transmitting hole 4 is located in the light-absorbing layer 3, and exits. The diffuse reflection layer 6 on the upper surface of the light-transmitting hole 4 is roughened, and it has As a result, the light emitted from the light transmission hole 4 is diverged after passing through the surface of the diffuse reflection layer 6 (see diverging light b in FIG. 2 ), thereby realizing normal display.

The light c of the ambient light is irradiated on the surface of the light-absorbing layer 3, most of the ambient light is absorbed, and only a very small part of the light is irradiated by the light-transmitting hole 4 of the light-absorbing layer 3, wherein the light entering the light-transmitting hole 4 is also partly reflected , the other part is refracted into the display, but compared to the light absorbed by the light-absorbing area of the light-absorbing layer 3, the reflected light is very little and can be ignored, and because the diffuse reflection layer 6 is set, the reflection of the light-transmitting hole 4 is also a kind of diffuse reflection. That is, the role of the diffuse reflection layer 6 is to make both the ambient light and the converging light on its two surfaces produce diffuse reflection at the same time.

Therefore, by adopting the anti-glare structure of this embodiment, the light of the display device 1 itself is not lost, but most of the ambient light will be absorbed, and only a very small part will enter the human eye, and because it is diffuse reflection, it enters the human eye. The intensity of the eye will be less. Based on this, it can be considered that the ambient light will not affect the brightness and contrast of the display, so an effective display under strong ambient light can be achieved.

Example 3:

This embodiment provides an anti-glare structure for a display device, as shown in Fig. 3 and Fig. 5, comprising a plurality of condenser lens lenses 2 arranged at intervals, which are used to be arranged outside the light-emitting surface of the display device 1 so that the display device 1 emits light. The light forms converging light; the light-absorbing layer 3 arranged on the outside of the condenser lens 2 is used to absorb ambient light; wherein, the light-absorbing layer 3 is provided with a light-transmitting hole 4 at a part of the position corresponding to the condenser lens 2, and the converging light Emitting through the light-transmitting hole 4; the light-emitting side of each of the light-transmitting holes 4 is provided with a diffuse reflection layer 6, and the projected area of the diffuse reflection layer 6 on the light-absorbing layer 3 is less than or equal to that of the light-transmitting hole 4 The projected area on the light-absorbing layer 3 , the diffuse reflection layer 6 is used to make the concentrated light form diffuse reflection.

The difference between this embodiment and Embodiment 2 is that the material of the light-absorbing layer 3 in this embodiment itself has strong hardness and self-protection performance, so there is no need to additionally set a whole layer of protective layer above the light-absorbing layer 3, for example, implementing Diffuse reflective layer 6 in Example 2. Alternatively, the diffuse reflection layer 6 in this embodiment only needs to be correspondingly arranged on the light exit side of the light transmission hole 4, so that the rough surface diffuse reflection layer 6 is only prepared above the light transmission hole 4 of the light absorption layer 3, so as to It is satisfied that the light emitted by the display device 1 can be diverged, so as to expand its propagation range.

Example 4:

This embodiment provides an anti-glare structure for a display device, which is used on a color filter substrate. The color filter substrate includes a display area and a non-display area around the display area. The display area is provided with a color filter 13. A black matrix 12 is arranged in the non-display area; a polarizer 15 is arranged between the anti-glare structure, the color filter 13 and the black matrix 12 . In the display area, the light-absorbing layer 3 is in direct contact with the outside of the condenser lens 2 , and in the non-display area, a plurality of spacers 5 are provided between the light-absorbing layer 3 and the polarizer 15 .

That is to say as shown in Figure 4, a plurality of spacers 5 are set between the light-absorbing layer 3 and the polarizer 15 in the non-display area, and the effect of the spacers 5 is: make there be space between the light-absorbing layer 3 and the polarizer 15. A buffer that, when used, also changes the light intensity at the touch location with the touch of a finger. Specifically, the spacer 5 can be made of polystyrene (PS) material commonly used in TFT-LCD.

Example 5:

This embodiment provides a color filter substrate, including the anti-glare structure of the above embodiment. Wherein, the color filter substrate includes a display area and a non-display area around the display area, the display area is provided with a color filter 13, and the non-display area is provided with a black matrix 12; the anti-glare structure and the color filter 13 A polarizer 15 is arranged between the black matrix 12 and the black matrix 12 .

Preferably, the light-absorbing layer 3 is in direct contact with the outside of the condenser lens 2 in the display area, and the light-absorbing layer 3 is in direct contact with the polarizer 15 in the non-display area.

That is to say, the light-absorbing layer 3 of embodiment 1 and embodiment 2 is a whole layer covering the outside of the polarizing plate 15, so because the thickness of the condenser lens is relatively large, the thickness of the light-absorbing layer 3 is thicker, and the thicker light-absorbing layer 3 The function is to make the product meet the needs of planarization.

Obviously, many changes can be made to the specific implementation of the above-mentioned embodiments; for example, the shape and material of the condensing lens can be adjusted according to needs, and the material and quantity of spacers can be changed according to actual conditions.

The display device may be any product or component with a display function such as a liquid crystal display panel, electronic paper, mobile phone, tablet computer, television, monitor, notebook computer, digital photo frame, navigator, and the like.

It can be understood that, the above embodiments are only exemplary embodiments adopted to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present utility model, and these variations and improvements are also regarded as the protection scope of the present utility model.
