AI Technical Summary
[0002]随着汽车内饰极简奢华风格理念的发展，汽车消费者对液晶显示屏的要求越来越高，传统的液晶显示屏只能在非显示区设置颜色图案层，如木纹效果图案，而显示区为了更好地显示内容，因此显示区无法制作颜色图案层只能避空，因此传统的液晶显示屏外围区域有木纹效果图案，而中间的显示区域熄屏时却呈现一片黑色，使得产品不够美观，降低了产品的竞争力
[0016]由于位于显示区的颜色图案层设置有多个尺寸极小的透孔，其可以通过蚀刻工艺腐蚀出极小透孔，人眼无法看到这些透孔，其覆盖区域为液晶显示屏对应的有效显示区域，当液晶显示屏息屏时，由于人眼无法看到这些透孔，液晶显示屏表现颜色图案层的画面，当液晶显示屏亮屏时，显示区域可以incell液晶显示模组展示的画面，即使得液晶显示屏在亮屏时可以正常显示，而在熄屏时又可以将显示区域隐藏，而达到全屏一体实现颜色图案层的显示效果，隐藏显示可以极大降低视觉落差，与汽车内饰完美融合，给汽车消费者以浑然天成的一体科技美感，以此提高产品的竞争力。

Technical Field
[0001] This utility model relates to the field of liquid crystal display technology, and more specifically, to a liquid crystal display screen with built-in display patterns. Background Technology
[0002] With the development of minimalist luxury style in car interiors, car consumers have higher and higher requirements for LCD screens. Traditional LCD screens can only set color pattern layers, such as wood grain effect patterns, in non-display areas. However, in order to better display content, the display area cannot have color pattern layers and can only be left blank. Therefore, traditional LCD screens have wood grain effect patterns on the outer area, but the central display area appears black when the screen is off, making the product less aesthetically pleasing and reducing its competitiveness. Utility Model Content
[0003] The technical problem this invention aims to solve is how to enable an LCD screen to display normally when the screen is on, and to hide the display area when the screen is off, thereby achieving a full-screen integrated display effect of color and pattern layers. The hidden display can greatly reduce the visual gap and perfectly blend with the car interior, giving car consumers a seamless and integrated technological aesthetic, thereby improving the product's competitiveness.
[0004] The technical problem to be solved by this utility model is achieved through the following technical solution:
[0005] To solve the above-mentioned technical problems, this utility model provides a liquid crystal display screen with a built-in display pattern, which includes an incell liquid crystal display module and a cover plate. The cover plate is attached to the top of the incell liquid crystal display module by OCA optical adhesive. A color pattern layer is provided on the lower surface of the cover plate, which covers the display area and the non-display area. A reverse cover ink layer is provided on the lower surface of the color pattern layer in the non-display area, and a plurality of extremely small through holes are provided on the color pattern layer in the display area.
[0006] In a preferred embodiment of the liquid crystal display screen with built-in display pattern provided by this utility model, the size of the through hole is 0.015mm-0.030mm.
[0007] In a preferred embodiment of the liquid crystal display screen with built-in display pattern provided by this utility model, the cover plate is made of tempered glass.
[0008] In a preferred embodiment of the liquid crystal display screen with built-in display pattern provided by this utility model, the thickness of the cover plate is 1.1mm-4.0mm, and the thickness of the OCA optical adhesive is 0.2mm-0.3mm.
[0009] In a preferred embodiment of the liquid crystal display screen with built-in display pattern provided by this utility model, the pattern of the color pattern layer is a wood grain pattern.
[0010] As a preferred embodiment of the liquid crystal display screen with built-in display pattern provided by this utility model, the color pattern layer has four layers, which respectively include a white layer, a red layer, a green layer and a blue layer stacked sequentially from bottom to top.
[0011] In a preferred embodiment of the liquid crystal display screen with built-in display pattern provided by this utility model, a membrane button is provided on the lower surface of the reverse ink layer, and the membrane button is connected to the motherboard.

[0015] This utility model has the following beneficial effects:
[0016] Because the color pattern layer in the display area has multiple extremely small through-holes, which can be etched using an etching process, these through-holes are invisible to the human eye. The area covered by these through-holes is the effective display area of the LCD screen. When the LCD screen is off, since the human eye cannot see these through-holes, the LCD screen displays the image of the color pattern layer. When the LCD screen is on, the display area can display the image shown by the in-cell LCD module. This means that the LCD screen can display normally when it is on, and can hide the display area when it is off, thus achieving a full-screen integrated display effect of the color pattern layer. The hidden display can greatly reduce the visual gap and blend perfectly with the car interior, giving car consumers a seamless and integrated technological aesthetic, thereby improving the product's competitiveness.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0025] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0026] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0027] This utility model provides a liquid crystal display screen with a built-in display pattern, which includes an incell liquid crystal display module and a cover plate. The cover plate is attached to the top of the incell liquid crystal display module by OCA optical adhesive. A color pattern layer is provided on the lower surface of the cover plate, which covers the display area and the non-display area. A reverse ink layer is provided on the lower surface of the color pattern layer in the non-display area, and a plurality of extremely small through holes are provided on the color pattern layer in the display area.
[0028] Because the color pattern layer in the display area has multiple extremely small through-holes, which can be etched using an etching process, these through-holes are invisible to the human eye. The area covered by these through-holes is the effective display area of the LCD screen. When the LCD screen is off, since the human eye cannot see these through-holes, the LCD screen displays the image of the color pattern layer. When the LCD screen is on, the display area can display the image shown by the in-cell LCD module. This means that the LCD screen can display normally when it is on, and can hide the display area when it is off, thus achieving a full-screen integrated display effect of the color pattern layer. The hidden display can greatly reduce the visual gap and blend perfectly with the car interior, giving car consumers a seamless and integrated technological aesthetic, thereby improving the product's competitiveness.
[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. The present invention will be described in detail below with reference to the accompanying drawings and embodiments, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0030] Example 1, please refer to Figure 1This utility model provides a liquid crystal display screen with a built-in display pattern, which includes an incell liquid crystal display module 1 and a cover plate 2. The cover plate 2 is attached to the top of the incell liquid crystal display module 1 by OCA optical adhesive 3. A color pattern layer 4 is provided on the lower surface of the cover plate 2, which covers the display area and the non-display area. A reverse cover ink layer 5 is provided on the lower surface of the color pattern layer 4 in the non-display area. The color pattern layer 4 in the display area is provided with a plurality of tiny through holes. Because the color pattern layer 4 in the display area has multiple extremely small through holes, which can be etched using an etching process, these through holes are invisible to the human eye. The area covered by these through holes is the effective display area of the LCD screen. When the LCD screen is off, since the human eye cannot see these through holes, the LCD screen displays the image of the color pattern layer 4. When the LCD screen is on, the display area can display the image shown by the in-cell LCD module 1. This means that the LCD screen can display normally when it is on, and can hide the display area when it is off, thus achieving a full-screen integrated display effect of the color pattern layer 4. The hidden display can greatly reduce the visual gap and blend perfectly with the car interior, giving car consumers a seamless and integrated technological aesthetic, thereby improving the product's competitiveness.
[0031] Furthermore, the size of the through hole is 0.015mm-0.030mm, the material of the cover plate 2 is tempered glass, the thickness of the cover plate 2 is 1.1mm-4.0mm, the thickness of the OCA optical adhesive 3 is 0.2mm-0.3mm, and the pattern of the color pattern layer 4 is a wood grain pattern.
[0032] Furthermore, the color pattern layer 4 has four layers, which include a white layer, a red layer, a green layer, and a blue layer stacked sequentially from bottom to top. These four ink layers are used for contrasting colors, with the ink colors being white, red, green, and blue respectively. The desired wood grain effect image is layered using image processing software, resulting in four corresponding white, red, green, and blue layers. These four layers of photoresist ink are then fabricated by coating and developing each layer on a white glass surface. The resulting wood grain pattern is achieved by stacking the four photoresist ink layers, and then a single etching process is used to create extremely small perforations.
[0033] Example 2, please refer to Figure 1 As a further optimization of Embodiment 1, in this embodiment, a membrane button 6 is provided on the lower surface of the reverse ink layer 5. The membrane button 6 is connected to the motherboard 7, which makes the product more diversified and can be adapted to more scenarios.
[0034] Furthermore, the membrane button 6 includes a PET film 61, on which an ITO pattern 62 and silver paste lines 63 are provided. This enables it to have built-in touch functionality. The surface of the PET film 61 is provided with double-sided adhesive 64, and the ITO pattern 62 and silver paste lines 63 on the PET film 61 realize the touch functionality.
[0035] Furthermore, the overlap between the visible area of the cover plate 2 and the AA area of the incell liquid crystal display module 1 is 0.5mm.
