Description

Technical Field

[0001] The present disclosure relates to the field of display technology, and in particular to a display panel and an electronic device. Background Art

[0002] With the development of display technology, users have higher and higher requirements for display devices such as mobile phones. Among them, the screen-to-body ratio is one of the users' concerns.

[0003] For display devices such as mobile phones, the front camera is one of the main structures that affects the screen-to-body ratio. Therefore, how to reduce the impact of the front camera on the screen-to-body ratio is a technical problem that needs to be solved urgently. Summary of the invention

[0004] The present disclosure provides a display panel and an electronic device to solve the deficiencies in the related art.

[0005] According to a first aspect of an embodiment of the present disclosure, there is provided a display panel, including:

[0006] A display area and a blind hole provided in the display area for light to pass through;

[0007] A planarization layer is provided in the array substrate of the display panel, and the side wall of the planarization layer facing the hole area includes a plurality of descending edges, and the connection parts between adjacent descending edges are parallel to the upper surface of the planarization layer.

[0008] Optionally, the display panel further includes:

[0009] The light shielding area is arranged between the display area and the hole area.

[0010] Optionally, a side wall of the planarization layer is located in the light-shielding area.

[0011] Optionally, the display panel further includes:

[0012] The spacing structure is arranged in the liquid crystal layer in the light-shielding area.

[0013] Optionally, the spacing structure is arranged corresponding to the connecting portion.

[0014] Optionally, the spacing structure includes at least one of the following:

[0015] Spacer columns, spacer balls.

[0016] Optionally, the spacing structure includes spacing columns, and the spacing columns are auxiliary spacing columns.

[0017] Optionally, the auxiliary spacers are arranged on a side of the liquid crystal layer close to the color filter substrate in the display panel, and each of the auxiliary spacers has an equal height.

[0018] According to a second aspect of the embodiments of the present disclosure, an electronic device is provided, including a display panel as described in the embodiments of the first aspect.

[0019] Optionally, the electronic device further includes:

[0020] An image acquisition device, located on a side of the display panel away from the light-emitting direction and corresponding to the hole region.

[0021] The technical solutions provided by the embodiments of the present disclosure may include the following beneficial effects:

[0022] As can be seen from the above embodiments, when forming the alignment layer of the liquid crystal layer on the planarization layer, the material of the alignment layer can flow from the top of the planarization layer along the side wall of the planarization layer to the hole region. Since the side wall of the planarization layer is provided to include a plurality of descending edges, the connection portion between adjacent descending edges can be relatively flat. For example, the connection portion between adjacent descending edges is parallel to the upper surface of the planarization layer.

[0023] Accordingly, the connection portion can generate a greater resistance to the flow of the alignment layer relative to the descending edge, so that the material of the alignment layer stays relatively uniformly on each connection portion, rather than accumulating in large amounts at the bottom of the hole region, so as to ensure that the thickness of the alignment layer is relatively uniform. Furthermore, it is ensured that during the subsequent curing process, the alignment layer can be completely cured, thereby avoiding problems caused by incomplete curing, that is, avoiding the material of the alignment layer overflowing from the surface of the alignment layer and affecting the light propagation in the hole region, or damaging other structures in the display panel.

[0024] Furthermore, when applying the display panel to an electronic device such as a mobile phone, the image acquisition device serving as a front camera can be disposed in the hole region and on a side of the display panel away from the light-emitting direction, thereby realizing the arrangement of the image acquisition device under the display panel to achieve a full-screen display.

[0025] And since it is avoided that the material of the alignment layer overflows from the surface of the alignment layer and affects the light propagation in the hole region, it is beneficial to ensure that the image acquisition device can acquire images with good effects.

[0026] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0038] In order to increase the screen ratio, it is considered to dispose the front camera under the screen, and collect the picture on the light-emitting side of the screen through the camera under the screen.

[0039] For a liquid crystal display panel, in order to dispose the camera under the screen, the adopted method is to open a blind hole in the display area of the liquid crystal display panel, and retain the liquid crystal layer in the hole area of the blind hole, without structures such as color filters and black matrices in the color film substrate, nor structures such as thin film transistors, gate lines, and data lines in the array substrate, so as to ensure that the hole area has a high light transmittance, and then dispose the camera in the hole area.

[0040] Figure 1 It is a cross-sectional schematic diagram of a hole area in the related art.

[0041] As Figure 1 shown, a planarization (PLN) layer is provided on the array substrate of the display panel, and the liquid crystal layer is provided between the array substrate and the color filter substrate ( Figure 1 not shown), specifically as Figure 1 shown, on top of the planarization layer of the array substrate, and an alignment layer (also referred to as an alignment layer) is provided between the liquid crystal layer and the planarization layer.

[0042] The alignment layer is generally made of polyimide (abbreviated as PI), and polyimide has fluidity before molding. Then, when setting the material of the alignment layer on the planarization layer, in the hole area, since there is no planarization layer, but only the transparent substrate of the array substrate is retained, there will be a large drop from the top of the planarization layer to the transparent substrate, resulting in part of the material of the alignment layer on the top of the planarization layer flowing into the hole area, thus forming a pile at the bottom of the hole area. Furthermore, during the subsequent solidification process, due to the accumulation of the material of the alignment layer, it is difficult to cure completely. The alignment layer near the bottom of the side wall of the planarization layer is not completely cured and still has a certain fluidity.

[0043] Then, during the subsequent use of the display panel, for example, when the display panel is applied to a mobile phone, the display panel will move frequently as the mobile phone moves, resulting in the above-mentioned material with a certain fluidity overflowing from the surface of the alignment layer, affecting the light propagation in the hole area, and even damaging other structures in the display panel.

[0044] Figure 2 is a cross-sectional schematic diagram of a display panel shown according to an embodiment of the present disclosure.

[0045] An embodiment of the present disclosure provides a display panel, the display panel is a liquid crystal display panel, the display panel can be applied to an electronic device with a display function, and the electronic device includes but is not limited to a mobile phone, a tablet computer, and a wearable device.

[0046] As Figure 2 shown, the display panel includes:

[0047] a display area and blind holes provided in the display area for light to pass through;

[0048] Wherein, a planarization layer is provided in the array substrate of the display panel, and the side wall of the planarization layer facing the hole area includes a plurality of descending edges, and the connecting portions between adjacent descending edges are parallel to the upper surface of the planarization layer, and the plurality of descending edges and connecting portions are in a stepped shape as a whole.

[0049] Wherein, the number of descending edges can be as Figure 3As shown, it is set to 3, and the number of falling edges can also be set according to needs. The angle between the falling edge and the connecting part can also be set according to needs, and the angle can be a sharp angle or a rounded corner, which can be specifically determined according to the manufacturing process.

[0050] It should be noted that in the hole area, the transparent substrates of the array substrate and the color filter substrate are provided, while other structures in the array substrate and the color filter substrate are not provided, such as the color filters, black matrices, etc. in the color filter substrate, and the thin film transistors, gate lines, data lines, etc. in the array substrate are not provided, so as to ensure that the hole area has high transparency. And pixel electrodes, common electrodes, alignment layers, polarizers and other structures can also be provided in the hole area.

[0051] In one embodiment, when forming the alignment layer of the liquid crystal layer on the planarization layer, the material of the alignment layer can flow from the top of the planarization layer along the side wall of the planarization layer to the hole area. Since the side wall of the planarization layer is provided with multiple falling edges, the connecting part between adjacent falling edges is relatively flat with respect to the falling edges. For example, the connecting part between adjacent falling edges is parallel to the upper surface of the planarization layer.

[0052] Accordingly, the connecting part can generate a greater resistance to the flow of the alignment layer with respect to the falling edge, so that the material of the alignment layer stays relatively uniformly on each connecting part, rather than accumulating in large quantities at the bottom of the hole area, so as to ensure that the thickness of the alignment layer is relatively uniform, and further ensure that in the subsequent curing process, the alignment layer can be completely cured, thus avoiding problems caused by incomplete curing.

[0053] For example, it can avoid the material of the alignment layer overflowing from the surface of the alignment layer and affecting the propagation of light in the hole area, or damaging other structures in the display panel.

[0054] Furthermore, when applying the display panel to electronic devices such as mobile phones, the image acquisition device serving as a front camera can be arranged in the hole area and on the side of the display panel away from the light-emitting direction, so as to realize arranging the image acquisition device under the display panel to achieve a full-screen display.

[0055] And since it avoids the material of the alignment layer overflowing from the surface of the alignment layer and affecting the propagation of light in the hole area, it is beneficial to ensure that the image acquisition device can acquire images with good effects.

[0056] It should be noted that as Figure 2 shown, in the display area, an array substrate is provided below the liquid crystal layer. The array substrate can include a planarization layer as Figure 2 shown, and can also include structures such as a gate insulating layer and a buffer layer; and Figure 2The color filter substrate not shown may be provided with color filters, such as red filters, green filters, and blue filters, in the display area, and may also be provided with a black matrix; and a touch sensor, such as a touch electrode, a photoelectric sensor with touch function, an ultrasonic sensor, etc., may also be provided on the display panel, which will not be elaborated here.

[0057] This embodiment is not only applicable to setting the camera under the screen, but also other light-gathering structures, such as light sensors, can be set in the hole area and on the side of the display panel away from the light-emitting direction, so as to realize setting other light-gathering structures under the display panel.

[0058] Figure 3 It is a schematic cross-sectional view of another display panel shown according to an embodiment of the present disclosure.

[0059] Optionally, as Figure 3 shown, the display panel may further include:

[0060] A light-shielding area, provided between the display area and the hole area.

[0061] In one embodiment, the light-shielding area is light-impermeable and can block the light in the display area from entering the hole area, so as not to affect the image acquisition of the image acquisition device in the hole area, which is beneficial to ensuring that the image acquired by the image acquisition device has a good effect.

[0062] Among them, the light-shielding area may specifically include a light-shielding material provided in the color filter substrate. The light-shielding material may use the same material as the black matrix in the color filter substrate, so that when the black matrix is formed, the light-shielding material in the light-shielding area can also be formed in the same process, which is beneficial to simplifying the manufacturing process.

[0063] Figure 4 It is a schematic structural diagram of an electronic device shown according to an embodiment of the present disclosure.

[0064] In one embodiment, taking the electronic device as a mobile phone as an example, for example, if a front camera needs to be set in the electronic device, then as Figure 4 shown, a blind hole is opened on the display panel in the above embodiment. The area outside the hole area of the blind hole is a light-shielding area. The front camera can be set in the hole area and on the side of the display panel away from the light-emitting direction, so that there is no need to set a front camera on the front of the mobile phone, reducing the screen-to-body ratio, which is beneficial to realizing a full-screen.

[0065] It should be noted that the position of the blind hole can be set according to the position of the front camera. For example, it can be set in the upper right corner of the display panel as Figure 4 shown, or can be set in other positions according to needs.

[0066] Figure 5 It is a schematic structural diagram of another electronic device shown according to an embodiment of the present disclosure.

[0067] In one embodiment, multiple front cameras can also be provided in the electronic device. For example, if two front cameras are provided, then as Figure 5 shown, two blind holes can be formed in the display panel in the above embodiment.

[0068] Optionally, the side wall of the planarization layer is located in the light shielding region.

[0069] Since the side wall of the planarization layer includes multiple descending edges, and there are connecting portions between adjacent descending edges, although both the planarization layer and the alignment layer can transmit light, the multiple descending edges and the connecting portions are not in the same plane, which still has a certain impact on the propagation of light.

[0070] In one embodiment, as Figure 3 shown, the side wall of the planarization layer can be located in the light shielding region. Since the light shielding region is light-impermeable, by setting the side wall of the planarization layer in the light shielding region, even if the side wall including multiple descending edges and connecting portions affects the propagation of light, the affected light will not be emitted from the light shielding region, thereby avoiding affecting the display effect of the display panel and the propagation of light in the hole region.

[0071] Optionally, the display panel further includes:

[0072] a spacer structure disposed in the liquid crystal layer of the light shielding region.

[0073] In one embodiment, in order to ensure that the propagation of light in the hole region is not easily affected, the spacer structure can be not provided in the hole region, and the light shielding region can be disposed along the edge of the hole region. The spacer structure (disposed on the color filter substrate and facing the array substrate) is disposed in the light shielding region, so that the spacer structure can not only support the cell thickness of the liquid crystal layer in the light shielding region, but also play a certain supporting effect on the cell thickness of the liquid crystal layer in the hole region.

[0074] It should be noted that the support for the cell thickness of the liquid crystal layer in this embodiment is different from that in the related art where the cell thickness of the liquid crystal layer is supported by a spacer structure.

[0075] Figure 6 It is a schematic diagram of the hole region in the related art. Figure 7 It is Figure 6 a cross-sectional schematic diagram of the structure shown along AA'.

[0076] As Figure 6 and Figure 7As shown, in the related art, in order to maintain the cell thickness of the liquid crystal layer in the display panel, a spacer structure, such as spacer posts, is provided in the liquid crystal layer to support the color filter substrate and the array substrate on both sides of the liquid crystal layer. In order to avoid the influence of the spacer posts on the light transmission performance of the hole region, no spacer posts are provided in the liquid crystal layer within the hole region. For the hole region, the cell thickness of the liquid crystal layer in the hole region is mainly supported by the spacer posts provided in the light-shielding region.

[0077] Since no spacer posts are provided in the liquid crystal layer within the hole region, the spacer posts provided in the light-shielding region outside the hole region will act as a fulcrum, causing a large depression on the surface of the liquid crystal layer within the hole region, and there will be a certain degree of upward warping in the display region outside the spacer region, thus forming a structure similar to a concave lens in the hole region, which will have an adverse impact on the optical characteristics of the lens collecting images below the hole region.

[0078] Based on this embodiment, since the side wall of the planarization layer is located within the light-shielding region, when a spacer structure is provided in the liquid crystal layer of the light-shielding region, at least part of the spacer structure can correspond to the surface of the side wall of the planarization layer facing the color filter substrate.

[0079] Figure 8 It is a cross-sectional schematic diagram of another display panel shown according to an embodiment of the present disclosure.

[0080] As Figure 8 shown (where the alignment layer is not shown), the side wall of the planarization layer includes 3 descending edges, where there are two connection parts B and C, and the upper surface A of the planarization layer. The surface of the upper surface A of the planarization layer facing the color filter substrate corresponds to a spacer structure (such as a spacer post) a, the surface of the connection part B facing the color filter substrate corresponds to a spacer structure b, and the surface of the connection part C facing the color filter substrate corresponds to a spacer structure c.

[0081] During the process of assembling the array substrate and the color filter substrate into a cell, it is necessary to fill liquid crystal between the array substrate and the color filter substrate. After the array substrate and the color filter substrate are assembled into a cell, they are very close to each other, which is sufficient to cause capillary action in the liquid crystal in the gap formed by the color filter substrate and the array substrate. The liquid crystal flowing along the gap will cause the liquid crystal substrate and the color filter substrate on both sides of the gap to approach each other.

[0082] During the process of the liquid crystal substrate and the color filter substrate approaching each other, the spacer structure closest to the planarization layer, such as spacer structure a, will first contact the upper surface A of the planarization layer, and then prevent the color filter substrate and the array substrate from approaching further. Then, spacer structure b will contact the connection part B, and then prevent the color filter substrate and the array substrate from approaching further. Finally, spacer structure c will contact the connection part C, and then prevent the color filter substrate and the array substrate from approaching further.

[0083] Among them, the distance between the upper surface A of the planarization layer and the spacer structure a is the smallest. Therefore, after the upper surface A of the planarization layer contacts the spacer structure a, the deformation generated by the array substrate and the color filter substrate is also the smallest. The distance between the connecting portion B and the spacer structure b is slightly larger. Therefore, after the connecting portion B contacts the spacer structure b, the deformation generated by the array substrate and the color filter substrate is also slightly larger. The distance between the connecting portion C and the spacer structure c is the largest. Therefore, after the connecting portion C contacts the spacer structure c, the deformation generated by the array substrate and the color filter substrate is also the largest.

[0084] This causes the liquid crystal layer between the array substrate and the color filter substrate to bend in the light-shielding area from the display area toward the hole area. The reason for the deformation of the liquid crystal layer is that there is surface tension on the surface of the liquid crystal layer. However, the surface tension of the liquid crystal layer is limited. Bending occurs outside the hole area, and the bending generated inside the hole area will decrease. This reduces the curvature of the depression of the liquid crystal layer in the hole area, thereby reducing the impact of the depression in the hole area on the image of the image acquisition device under the display panel.

[0085] Optionally, the spacer structure is provided corresponding to the connecting portion.

[0086] In one embodiment, it can be set that all the spacer structures correspond to the connecting portions, that is, in the region corresponding to the descending edge in the side wall of the planarization layer, no spacer structure is provided. Because even if spacer posts are provided in this part of the region, it is difficult for the spacer structure to stably contact the descending edge to play a supporting role. By setting the spacer structure corresponding to the connecting portion, the spacer structure can stably contact the connecting portion to play an effective supporting role. And since there is no need to provide spacer structures in the region corresponding to the descending edge, the number of spacer posts provided can be reduced on the basis of ensuring the supporting effect.

[0087] Optionally, the spacer structure includes at least one of the following:

[0088] Spacer posts, spacer balls.

[0089] Optionally, the spacer structure includes spacer posts, and the spacer posts are auxiliary spacer posts.

[0090] In one embodiment, spacer posts can be selected as the spacer structure to support the liquid crystal layer, or spacer balls can be selected as the spacer structure to support the liquid crystal layer.

[0091] In the case of using spacer columns to support the liquid crystal layer, sub-spacer columns (also called daughter spacer columns) can be specifically used to support the liquid crystal layer. Since the spacer columns include two types: main spacer columns and sub-spacer columns, where the length of the main spacer columns is longer than that of the sub-spacer columns, when the liquid crystal layer is not deformed, it will play a role in supporting the cell gap of the liquid crystal layer, which may cause the junction between the hole region and the display region to not deform at all when subjected to an external force, making it difficult to achieve Figure 8 the technical effects in the embodiments shown in Figure 8 However, the sub-spacer columns will only play a supporting role when they are squeezed to a certain extent by an external force (for example, when they contact the planarization layer as shown in Figure 6 ), so as to support the cell gap of the liquid crystal layer at the junction on the basis of a certain deformation, in order to achieve

[0092] the technical effects in the embodiments shown.

[0093] Optionally, the sub-spacer columns are arranged on the side of the liquid crystal layer close to the color filter substrate in the display panel, and the height of each sub-spacer column is equal.

[0094] In one embodiment, the height of the sub-spacer columns in the light-shielding region can be set to be equal, so that during the approach of the liquid crystal substrate and the color filter substrate, the spacer structure closer to the planarization layer can contact the planarization layer first, and the spacer structure farther from the planarization layer can contact the planarization layer later, thereby ensuring that the liquid crystal layer between the array substrate and the color filter substrate has a bend from the display region to the hole region direction in the light-shielding region, so that at the position in the light-shielding region closest to the hole region, the height of the liquid crystal layer surface is close to the height of the liquid crystal layer surface in the hole region, thereby effectively reducing the deformation of the liquid crystal layer surface in the hole region.

[0095] The embodiments of the present disclosure also propose an electronic device, including the display panel described in any of the above embodiments.

[0096] Among them, the electronic device includes but is not limited to electronic devices such as mobile phones, tablet computers, and wearable devices.

[0097] Optionally, the electronic device further includes:

[0098] An image acquisition device, arranged in the hole region and on the side of the display panel away from the light-emitting direction.

[0099] In one embodiment, the image acquisition device arranged in the hole region may refer to the entire image acquisition device or the lens of the image acquisition device.

[0100] The image acquisition device can be used as a front camera in an electronic device. By disposing the image acquisition device in the hole region and on a side of the display panel away from the light-emitting direction, rather than on the front of the electronic device, it is convenient to set a display area with a higher screen-to-body ratio on the front of the electronic device, which is beneficial to implementing a full-screen based on a liquid crystal display panel.

[0101] And based on the above embodiments, the alignment layer in the display panel can be completely cured, thereby avoiding problems caused by incomplete curing. Thus, it is avoided that the material of the alignment layer overflows from the surface of the alignment layer and affects the propagation of light in the hole region, which is beneficial to ensuring that the image acquisition device captures images with good effects.
