Description

Technical Field

[0001] The present invention relates to the field of touch display screens, and in particular to a display cover plate and a preparation method thereof, a display module and an electronic device. Background Art

[0002] In the field of vehicle interiors, traditional vehicle touch screens can no longer meet user needs. Therefore, based on traditional vehicle wood grain decorative parts, a vehicle wood grain display screen with hidden display function has been derived. That is, by processing translucent wood grain ink on the display cover, the picture can be displayed normally when the screen is on, and the decorative texture pattern is presented when the screen is off, realizing the effect of matching the display screen with the interior parts.

[0003] To achieve this effect, the prior art typically adds decorative texture ink and cover ink to the display cover or diaphragm structure, and provides a layer of integral black ink in the frame area. The ink area is provided with numerous micropores or micropatterns to allow external light to pass through. Traditionally, laser drilling is often used to create micropores or micropatterns in the ink area. While laser drilling can achieve the desired effect, the required number of micropores and micropatterns, typically exceeding one million, requires a long processing time, resulting in low overall production capacity. Furthermore, the laser can cause micro-damage to the processed glass, reducing its overall strength. The micropores or micropatterns can also produce moiré patterns, which can lead to optical defects. Summary of the Invention

[0004] The present invention aims to solve at least one problem in the background technology. To this end, the present invention proposes a display cover plate and its preparation method, a display module and an electronic device. The display cover plate is provided with a transparent body first, and a texture layer and an ink layer are successively filled in the gap between the transparent bodies, so that the internal light can only be emitted from the transparent body, so that it can display normally when lit and can display decorative textures when the screen is off, and avoids the need to punch holes in the substrate to allow internal light to pass through, thereby increasing the overall strength of the display cover plate, while improving product production efficiency and product yield, and ultimately improving the display effect of the display module and electronic device.

[0005] A method for preparing a display cover according to an embodiment of the first aspect of the present invention includes:

[0006] Providing a substrate, the substrate comprising a first surface and a second surface corresponding to each other;

[0007] forming a plurality of transparent bodies having heights on the first surface;

[0008] forming a texture layer on the first surface, wherein the texture layer fills gaps between the plurality of transparent bodies;

[0009] forming a first ink layer on the texture layer, wherein the ink layer covers the top of the transparent body;

[0010] removing the first ink layer on the top of the transparent body;

[0011] A second ink layer is formed on the edge of the side of the first ink layer.

[0012] It can be seen that by first setting a transparent body on the display cover plate, and filling the gap between the transparent bodies with a texture layer and an ink layer in turn, the internal light can only be emitted from the transparent body, so that it can be displayed normally when it is lit, and the decorative texture can be displayed when the screen is off, and the internal light can be transmitted by punching holes in the substrate is avoided, thereby increasing the overall strength of the display cover plate and improving product production efficiency and product yield.

[0013] According to another embodiment of the present invention, the transparent body is made of transparent photoresist material, and forming multiple transparent bodies with heights on the first surface specifically includes: forming multiple transparent bodies on the first surface by photolithography, and at least some of the transparent bodies have the same height.

[0014] According to another embodiment of the present invention, forming a texture layer on the first surface, and the texture layer filling the gaps between the plurality of transparent bodies, specifically includes: forming a texture layer on the first surface by silk screen printing, spraying or inkjet printing, and the texture layer filling the gaps between the plurality of transparent bodies.

[0016] According to another embodiment of the present invention, the removing of the first ink layer on the top of the transparent body specifically includes: polishing the first ink layer on the substrate based on the height of the transparent body until the top of all the transparent bodies is exposed relative to the first ink layer.

[0017] According to another embodiment of the present invention, forming the second ink layer on the edge of the side of the first ink layer specifically includes: screen printing the second ink layer on the edge of the side of the first ink layer.

[0019] It can be seen that by arranging a transparent body on the substrate and filling the texture layer and the ink layer in the gap between the transparent bodies, light can be transmitted through the transparent body, so that the decorative texture can be displayed when the screen is off and normal display can be achieved when it is lit. At the same time, it avoids the need to achieve light transmission through laser punching on the substrate, increases the overall strength of the display cover, and improves product production efficiency and product yield.

A transparent body is first provided on the display cover plate, and a texture layer and an ink layer are filled in the gap between the transparent bodies. Light is transmitted through the transparent body, thereby displaying a decorative texture when the screen is off and displaying normally when the screen is on.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0048] In the description of the present invention, it should be understood that a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0049] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0050] To illustrate the display cover plate and its preparation method, display module and electronic device provided in this application, they are described in detail below in conjunction with the accompanying drawings and textual descriptions of the embodiments.

[0051] Reference below Figures 1-6 The method for preparing the display cover according to the first embodiment of the present invention is described as follows: Figure 1 As shown, the steps include:

[0052] Step S100: providing a substrate, the substrate comprising a first surface and a second surface corresponding to each other.

[0053] Specifically, the substrate includes a first surface and a second surface, opposite to each other. The first surface is located on the side where light enters the substrate, and the second surface is located on the side where light passes through the substrate. The substrate can be made of any material, including cover glass or a membrane. In this embodiment, the substrate is made of cover glass.

[0054] Step S200: forming a plurality of transparent bodies with height on the first surface.

[0055] Specifically, the transparent body is a component that has a fixed shape and allows light to pass through. In this embodiment, the material of the transparent body is a photolithographic transparent photoresist material. Furthermore, the transparent body has a certain height relative to the first surface of the substrate. The height of the transparent body can be selected according to the specific usage scenario and is not specifically limited here. Furthermore, the shape of the transparent body can be selected according to the specific usage scenario. In this embodiment, the shape of the transparent body is a cylinder. Furthermore, the size of the transparent body needs to be determined according to the transmittance requirements of the display cover and the moiré matching effect of the LCM component matched therewith. For example, the transmittance of the display cover is 30%. At this time, the diameter of the cylindrical transparent body is 30μm, and the distance between the cylindrical transparent bodies is 30μm. Alternatively, the length of the line transparent body is 30μm, and the opening rate of the line transparent body is 30%. Furthermore, in order to reduce the moiré phenomenon, multiple transparent bodies can be set to irregular shapes or irregular arrangement designs.

[0056] Step S300: forming a texture layer on the first surface, and the texture layer fills the gaps between the plurality of transparent bodies.

[0057] Specifically, a texture layer is formed on the first surface of the substrate. The texture layer is used to provide the display cover with the required texture appearance. The texture layer can present wood grain and other patterns when the screen is off, and can display normally when the screen is on. Furthermore, the material of the texture layer can be photocuring glue, embossing glue or CMYK four-color ink.

[0058] Step S400: forming a first ink layer on the texture layer, and the ink layer covers the top of the transparent body.

[0059] Specifically, the first ink layer is formed on the texture layer, and the first ink layer covers the top of multiple transparent bodies, that is, the first ink layer covers multiple transparent bodies at this time. The first ink layer is a light-shielding layer, which is used to reduce the reflection of incident light, thereby avoiding the problem of the texture layer being visible when the screen is off. Furthermore, the color of the first ink layer can be black, gray, blue, purple, etc. In this embodiment, the color of the first ink layer is black.

[0060] Step S500: clearing the first ink layer on the top of the transparent body.

[0061] Specifically, the entire surface of the first ink layer is cleared until the first ink layer on the top of the transparent body is completely removed, exposing the top of the transparent body. It can be understood that by clearing the first ink layer on the top of the transparent body, internal light can pass through the transparent body normally. At this time, other areas outside the transparent body still have the texture layer and the first ink layer. The first ink layer serves as a light-shielding layer of the texture layer, which is used to reduce the reflection of incident light, thereby avoiding the problem of the texture layer being visible when the screen is off.

[0062] Step S600: forming a second ink layer on the edge of the side of the first ink layer.

[0063] Specifically, a second ink layer is formed on the edge of at least one side of the first ink layer. The second ink layer is used to match the chromaticity of the LCM component after the display cover is bonded to the LCM component, thereby achieving a black effect in the border area and the visible area. Specifically, the second ink layer uses ink with a chromaticity similar to that of the LCM component bonded thereto, thereby achieving good consistency between the border area and the visible area when the screen is off.

[0064] It can be seen that the preparation method of the display cover plate of the embodiment of the present invention is to first set a transparent body on the substrate, and successively fill the texture layer and the ink layer in the gap between the transparent bodies, so that the internal light can only be emitted from the transparent body, so that it can display normally when it is lit, and can display the decorative texture when the screen is off, and avoids the need to punch holes in the substrate to allow internal light to pass through, thereby increasing the overall strength of the display cover plate, while improving product production efficiency and product yield. After the display cover plate and the display components are bonded to form a display module, the display effect of the display module is finally improved, and the user experience is improved.

[0065] According to one embodiment of the present invention, Figure 2 As shown, the transparent body is made of transparent photoresist material. Step S200: forming a plurality of transparent bodies with height on the first surface, specifically comprising the steps of:

[0066] Step S210: forming a plurality of transparent bodies on the first surface by photolithography, and at least some of the transparent bodies have the same height.

[0067] Specifically, multiple transparent bodies can have the same height and shape, which is convenient for processing and manufacturing, and there is at least partial irregular arrangement between the multiple transparent bodies, or some transparent bodies have different shapes. It can be understood that by photoetching the transparent body on the first surface to achieve light transmittance of the substrate, it is possible to avoid punching holes in the substrate, thereby enhancing the overall hardness. At the same time, at least some transparent bodies have different shapes or irregular arrangement designs, which can further reduce the moiré phenomenon and improve the overall display effect.

[0068] According to one embodiment of the present invention, Figure 3 As shown, step S300: forming a texture layer on the first surface, and the texture layer fills the gaps between the plurality of transparent bodies, specifically comprising the steps of:

[0069] Step S310: forming a texture layer on the first surface by silk screen printing, spraying or inkjet printing, and the texture layer fills the gaps between the plurality of transparent bodies.

[0070] Specifically, after photolithography of multiple transparent bodies on the substrate, a texture layer can be formed in the gaps between the multiple transparent bodies by silk screen printing, spraying or inkjet printing. The texture layer completely fills the gaps between the transparent bodies, and is used to achieve normal display when the screen is on, and present wood grain and other patterns when the screen is off.

[0071] According to one embodiment of the present invention, Figure 4 As shown, step S400: forming a first ink layer on the texture layer, and the ink layer covers the top of the transparent body, specifically including the steps of:

[0072] Step S410: forming a first ink layer on the texture layer by silk screen printing, spraying or inkjet printing, and the ink layer covers the top of the transparent body.

[0073] Specifically, after the texture layer is formed, a first ink layer is formed above the texture layer and the transparent body by silk screen printing, spraying or inkjet printing. At this time, the total height of the first ink layer and the texture layer is greater than the height of the transparent body, thereby achieving overall coverage of the transparent body by the first ink layer.

[0074] According to one embodiment of the present invention, Figure 5 As shown, step S500: removing the first ink layer on the top of the transparent body, specifically comprising the steps of:

[0075] Step S510 : polishing the first ink layer on the substrate based on the height of the transparent bodies until the tops of all the transparent bodies are exposed relative to the first ink layer.

[0076] Specifically, after the first ink layer is formed, the thickness of the first ink layer can be gradually reduced by polishing until the first ink layer on the top of the transparent body is completely removed, so that light can be incident and emitted through the transparent body. At the same time, there is still the first ink layer above the texture layer, which prevents internal light from being emitted from above the texture layer and affecting the overall display effect.

[0077] According to one embodiment of the present invention, Figure 6 As shown, step S600: forming a second ink layer on the edge of the side of the first ink layer, specifically comprising the steps of:

[0078] Step S610: screen-printing a second ink layer on the side edge of the first ink layer.

[0079] Specifically, by forming a second ink layer on the edge of at least one side of the first ink layer by silk screen printing, the color of the LCM component can be matched after the display cover is bonded to the LCM component, thereby achieving good consistency between the border area and the visible area when the screen is off.

[0080] Reference below Figure 7-11 A display cover plate 100 according to an embodiment of the second aspect of the present invention is described below. Figure 7-11 is a diagram showing the process of preparing the cover plate 100, such as Figure 7-11 As shown, the display cover 100 includes a substrate 110. Specifically, the substrate 110 includes a corresponding first surface 111 and a second surface 112. Further, a plurality of transparent bodies 120 with a height are provided on the first surface 111 of the substrate 110, and gaps 121 are provided between the plurality of transparent bodies 120. At the same time, a texture layer 130 and a first ink layer 140 are sequentially provided on the first surface 111 of the substrate 110. The texture layer 130 and the first ink layer 140 fill the gaps 121 between the transparent bodies 120. The texture layer 130 is used to provide the display cover 100 with the required texture appearance. The texture layer 130 can present wood grain and other patterns when the screen is off, and can display normally when the screen is on. The first ink layer 140 is used to reduce the reflection of incident light, thereby avoiding texture The problem that the layer 130 is visible when the screen is off, and the second ink layer 150 is provided on the edge of the side of the first ink layer 140, it can be seen that the display cover 100 of the present application sets a transparent body 120 on the substrate 110, and fills the texture layer 130 and the first ink layer 140 in the gap 121 between the transparent body 120, and realizes light transmission through the transparent body 120, so that the decorative texture can be displayed when the screen is off and normal display can be achieved when the screen is lit. At the same time, it avoids the light transmission through laser punching on the substrate 110, increases the overall strength of the display cover 100, and improves the product production efficiency and product yield. After the display cover 100 and the display component 200 are bonded to the display module 10, the display effect of the display module 10 is finally improved, and the user experience is improved.

[0081] It should be noted that the substrate 110 includes a first surface 111 and a second surface 112, which are opposite to each other. The first surface 111 is located on the side where light is incident on the substrate 110, and the second surface 112 is located on the side where light passes through the substrate 110. The material of the substrate 110 includes any one of cover glass and a film. In this embodiment, the material of the substrate 110 is cover glass.

[0082] It should be noted that the transparent body 120 is a component having a fixed shape while allowing light to pass through. In this embodiment, the material of the transparent body 120 is a photolithographic transparent photoresist material. Furthermore, the transparent body 120 has a certain height relative to the first surface 111 of the substrate 110. The height of the transparent body 120 can be selected according to the specific usage scenario and is not specifically limited here. Furthermore, the shape of the transparent body 120 can be selected according to the specific usage scenario. In this embodiment, the transparent body 120 is cylindrical. Furthermore, the size of the transparent body 120 needs to be determined based on the transmittance requirements of the display cover 100 and the moiré matching effect of the LCM component matched therewith. For example, if the transmittance of the display cover 100 is 30%, the diameter of the cylindrical transparent body 120 is 30 μm, and the distance between the cylindrical transparent bodies 120 is 30 μm. Alternatively, the length of the linear transparent body 120 is 30 μm, and the open area ratio of the linear transparent body 120 is 30%. Furthermore, to reduce the moiré phenomenon, the multiple transparent bodies 120 can be set to an irregular shape or an irregular arrangement design.

[0083] It should be noted that the texture layer 130 is formed on the first surface 111 of the substrate 110. The texture layer 130 is used to provide the display cover 100 with the required texture appearance. The texture layer 130 can present wood grain and other patterns when the screen is off, and can display normally when the screen is on. Furthermore, the material of the texture layer 130 can be photocuring glue, embossing glue or CMYK four-color ink.

[0084] It should be noted that the first ink layer 140 is formed on the texture layer 130. The first ink layer 140 is a light-shielding layer, which is used to reduce the reflection of incident light, thereby avoiding the problem that the texture layer 130 is visible when the screen is off. Furthermore, the color of the first ink layer 140 can be black, gray, blue, purple, etc. In this embodiment, the color of the first ink layer 140 is black.

[0085] It should be noted that a second ink layer 150 is formed on the edge of at least one side of the first ink layer 140. The second ink layer 150 is used to match the chromaticity of the LCM component after the display cover 100 is bonded to the LCM component, thereby achieving an integrated black effect between the border area and the visible area. Specifically, the second ink layer 150 uses ink with a chromaticity similar to that of the LCM component bonded thereto, thereby achieving a good consistency effect between the border area and the visible area when the screen is off.

[0086] According to another embodiment of the present invention, Figure 7-11As shown, the shape of the transparent body 120 is a long strip or a cylinder. It can be understood that by making the transparent body 120 into a long strip, it is possible to set a transparent long strip line on the substrate 110, and the light is emitted to the outside at the line. Alternatively, by making the transparent body 120 into a cylinder, it is possible to set a transparent cylinder on the substrate 110, and the light is emitted from the cylinder, which is equivalent to the light being emitted from the hole to the outside.

[0087] It should be noted that, in this embodiment, the transparent body 120 is made of transparent photoresist material, and a plurality of transparent bodies 120 can be formed on the first surface 111 by photolithography.

[0088] It should be noted that, in some other embodiments, the shape of the transparent body 120 may be partially strip-shaped and partially cylindrical, or the transparent body 120 may also include other regular or irregular shapes. It is understandable that the shape of the transparent body 120 can be determined according to the specific usage scenario and no specific limitation is made here.

[0089] It should be noted that the size of the transparent body 120 can be determined according to the specific usage scenario and is not specifically limited here.

[0090] Reference below Figure 12 A display module 10 according to an embodiment of the third aspect of the present invention is described. Figure 12As shown, the display module 10 includes a display component 200 and a display cover 100. Specifically, the display component 200 has a light incident surface, and the display cover 100 is laminated with the light incident surface of the display component 200. Specifically, the display cover 100 includes a substrate 110 having a corresponding first surface 111 and a second surface 112. A plurality of transparent bodies 120 with a height are provided on the first surface 111 of the substrate 110, and gaps 121 are provided between the plurality of transparent bodies 120. At the same time, a texture layer 130 and a first ink layer 140 are sequentially provided on the first surface 111 of the substrate 110. The texture layer 130 and the first ink layer 140 fill the gaps 121 between the transparent bodies 120, and the edges of the sides of the first ink layer 140 are A second ink layer 150 is provided on the edge. It can be seen that the display module 10 of the present application sets a transparent body 120 on the substrate 110 of the display cover 100, and fills the texture layer 130 and the first ink layer 140 in the gap 121 between the transparent body 120. Light is transmitted through the transparent body 120, so that the decorative texture can be displayed when the screen is off and normal display can be achieved when the screen is lit. At the same time, it avoids the light transmission through laser punching on the substrate 110, increases the overall strength of the display cover 100, and improves product production efficiency and product yield. After the display cover 100 and the display component 200 are bonded to form the display module 10, the display effect of the display module 10 is finally improved, and the user experience is improved.

[0091] Reference below Figure 13 An electronic device 1 according to an embodiment of the third aspect of the present invention is described. Figure 13As shown, the display module 10 includes a display component 200 and a display cover 100. The display component 200 has a light incident surface. The display cover 100 is laminated with the light incident surface of the display component 200. Specifically, the display cover 100 includes a substrate 110 having a corresponding first surface 111 and a second surface 112. A plurality of transparent bodies 120 with a height are provided on the first surface 111 of the substrate 110, and gaps 121 are provided between the plurality of transparent bodies 120. At the same time, a texture layer 130 and a first ink layer 140 are sequentially provided on the first surface 111 of the substrate 110. The texture layer 130 and the first ink layer 140 fill the gaps 121 between the transparent bodies 120, and the side of the first ink layer 140 is provided with a plurality of transparent bodies 120. A second ink layer 150 is provided on the edge. It can be seen that the display module 10 of the present application sets a transparent body 120 on the substrate 110 of the display cover 100, and fills the texture layer 130 and the first ink layer 140 in the gap 121 between the transparent body 120. Light is transmitted through the transparent body 120, so that the decorative texture can be displayed when the screen is off and normal display can be achieved when the screen is on. At the same time, light transmission through laser punching on the substrate 110 is avoided, thereby increasing the overall strength of the display cover 100 and improving product production efficiency and product yield. After the display cover 100 and the display component 200 are bonded to form the display module 10, the display effect of the display module 10 and the electronic device 1 are finally improved, thereby improving the user experience.
