Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention discloses an ultrathin touch display screen, which is shown in fig. 1 to 3, wherein fig. 1 is a schematic position diagram of a touch film 1 of the ultrathin touch display screen provided by the embodiment of the invention; fig. 2 is a schematic position diagram of a display screen 2 in the ultrathin touch display screen according to the embodiment of the present invention; fig. 3 is a schematic position diagram of an ultra-thin touch display screen 3 according to an embodiment of the present invention; the method comprises the following steps:
the optical adhesive used for bonding between the touch film and the polaroid is pre-hollowed optical adhesive, and the polaroid is pre-hollowed polaroid;
the pre-hollowed optical adhesive and the pre-hollowed polaroid are used for jointly forming a cavity structure for arranging the binding and positioning of the FPC.
It should be noted that the overall structure of the touch display screen 3 provided in the embodiment of the present invention is, from top to bottom, a cover plate, a touch film 1, and a display screen 2 in sequence; the cover plate is usually a glass plate, but may be a cover plate made of other materials as necessary. The optical cement used for gluing the cover plate and the touch film 1 and the display screen 2 is generally an OCA (optical Clear Adhesive) or an SCA (Solid optical cement), although other types of glues may be used if necessary.
The OCA optical cement has the advantages that: 1. glare can be reduced, loss of light emitted by the LCD can be reduced, brightness of the LCD can be increased, high transmittance can be provided, and energy consumption can be reduced; 2. increasing the contrast, especially under strong light irradiation; 3. the surface connection has higher strength; 4. avoiding Newton rings; 5. the surface of the product is smoother; 6. without boundaries, the visible area is enlarged. The SCA optical adhesive has excellent light transmission, definition and adhesion, excellent moisture resistance, heat resistance and weather resistance, particularly excellent shock resistance and explosion resistance, and greatly improves the overall safety, reliability, durability and attractiveness of the touch screen. Therefore, the OCA glue and the SCA glue are widely applied to gluing of each element of the touch display screen.
It should be further noted that, in the prior art, in the process of gluing the cover plate and the touch film 1 by using the optical adhesive, an FPC binding site 5(Flexible Printed Circuit) needs to be installed on the upper surface of the touch film 1, and the FPC binding site 5 is used for binding an FPC to the upper surface of the touch film 1, so that parameter information such as patterns on the touch film 1 is sent to a control main board of a corresponding electronic display device.
In the embodiment of the invention, the optical adhesive used for adhesion between the touch film 1 and the polarizer 4 is pre-hollowed optical adhesive, and the polarizer 4 is pre-hollowed polarizer; therefore, the pre-hollowed optical adhesive and the pre-hollowed polaroid jointly form a cavity structure for arranging the FPC binding position, then the formed cavity structure is used for placing the FPC binding position 5, and the FPC binding position 5 is used for combining the FPC on the lower surface of the touch film 1, so that parameter information such as patterns on the touch film 1 is sent to a control mainboard of corresponding electronic display equipment. It should be noted that the portion of the polarizer that is hollowed in advance is a corner of the polarizer or a portion of the polarizer that is provided with adhesive, etc., that is, the hollowed polarizer does not affect the function of the display screen that utilizes the polarizer to form images.
According to the ultrathin touch display screen provided by the embodiment of the invention, the optical adhesive and the polaroid used for adhesion between the touch film and the polaroid are hollowed in advance to form the cavity structure for arranging the FPC binding position together, and then the formed cavity structure is used for arranging the FPC binding position.
In addition, in order to make the thickness of the touch display screen 3 provided in the embodiment of the present invention thinner, the material of the touch film 1 may be a PET material, a COP material, a TCTF material, or other types of materials if necessary. The process for preparing the touch film 1 includes a brass yellow process, a silver yellow process and a laser silver process, and can also be a mixture of the brass yellow process, the silver yellow process and the laser silver process, and it needs to be noted that the ultrathin and ultra-narrow-edge touch film 1 can be prepared by using the materials and the processes.
The display panel 2 may be a TFT (Thin Film Transistor), or may be an OLED (organic light-emitting diode). It should be noted that the TFT display screen is a mainstream display device in various notebook computers and desktop computers, and each liquid crystal pixel on the display screen is driven by a thin film transistor integrated behind the pixel, so the TFT display screen is also an active matrix liquid crystal display device, and has the advantages of high responsivity, high brightness, high contrast, and the like. The OLED display has the advantages of self-luminescence, wide viewing angle, almost infinite contrast, low power consumption, extremely high response speed, and the like, and thus is widely applied to electronic display devices.
The touch film 1 is glued on the TFT and the OLED, so that the touch display device with the ultrathin and the ultra-narrow edge can be prepared, and the touch display device with the flexible ultrathin and the ultra-narrow edge can also be prepared.
It should be further explained that imaging of the touch display screen provided by the embodiment of the invention must depend on polarized light, and all display screens have front and rear polarizers tightly attached to the display screen. The polarizer 4 is typically a polarizer. In the case of a display panel made of liquid crystal display panels, the polarizer generally facing the eye is frosted to dissipate surface reflections and to scatter light to increase the viewing angle of the liquid crystal display. For a projector where any scattering will cause a loss of light, the liquid crystal sheet for the projector should ideally have a viewing angle of 0 degrees, i.e. no light is present when the sheet is viewed off-normal. Of course, this is impossible to achieve, but the closer to the viewing angle of 0 degree, the higher the light utilization rate, so that after the frosted polarizer is replaced by the flat polarizer, the brightness of the projector to the wall is greatly improved, and the improved range is 50-80%, which is the reason of the polarizer for the display screen.
In the embodiment of the invention, the number of the FPC binding positions 5 is N, wherein N is an integer greater than or equal to 1. It should be noted that, in the touch display screen 3 provided in the embodiment of the present invention, the number of the touch films 1 is two, the FPC is glued on the lower surface of the touch film by using 3 FPC binding bits 5, and the parameter information such as the pattern on the touch film is acquired by using the glued FPC circuit, so as to implement the function of double-layer pattern multi-point touch. It should be further explained that most of the ONCELL structures in the prior art can only realize the function of multi-point touch with single-layer patterns, while the ONCELL structure can realize the function of multi-point touch with double-layer patterns, which is very expensive. On one hand, compared with a double-layer touch film structure, the ultrathin touch display screen provided by the embodiment of the invention is thinner; on the other hand, compared with the ONCELL structure, the cost is greatly lower than that of the ONCELL with double-layer pattern multi-point touch while the double-layer pattern multi-point touch function is realized. Of course, the number of FPC bonding locations 5 may be other values as necessary.
In addition, the ultrathin touch display screen provided by the embodiment of the invention has the following advantages:
the touch display screen provided by the embodiment of the invention can be customized according to the needs of a user, for example, the structure collocation of the touch display screen is more flexible; for example, in order to obtain a thinner touch display screen, a user may remove the FPC binding position between the cover plate and the touch film, thereby obtaining a thinner touch display screen.
Since each component of the touch display screen, such as the cover plate, the touch film and the display screen, is manufactured separately, the yield of the touch display screen is higher, and the industrial production of the touch display screen is facilitated; meanwhile, the touch screen is simple to manufacture, so that the cost is reduced, and the touch screen is more beneficial to commercial application.
Finally, the ultrathin touch display screen provided by the embodiment of the invention is easy to separate, so that when the touch display screen breaks down, the maintenance is facilitated.
Correspondingly, the invention further provides electronic display equipment which comprises the ultrathin touch display screen. For the description of the specific ultrathin touch display screen, the description is omitted here.
Finally, it should also be noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
The ultrathin touch display screen and the electronic display device provided by the invention are described in detail, a specific example is applied in the text to explain the principle and the implementation mode of the invention, and the description of the embodiment is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
