Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

In order to improve the proportion of the screen, a front camera is arranged below the screen, and pictures on the light emitting side of the screen are collected through the camera below the screen.

For the liquid crystal display panel, in order to set the camera below the screen, a blind hole is formed in a display area of the liquid crystal display panel, a liquid crystal layer is reserved in the hole area of the blind hole, and structures such as a color filter, a black matrix and the like in a color film substrate and structures such as a thin film transistor, a gate line, a data line and the like in an array substrate are not provided, so that the hole area is ensured to have high light transmittance, and then the camera is set in the hole area.

Fig. 1 is a schematic cross-sectional view of a hole region in the related art.

As shown in fig. 1, a planarization (P L N) layer is disposed on an array substrate of the display panel, a liquid crystal layer is disposed between the array substrate and a color filter substrate (not shown in fig. 1), specifically, as shown in fig. 1, the liquid crystal layer is disposed on the planarization layer of the array substrate, and an alignment layer (also referred to as an alignment layer) is disposed between the liquid crystal layer and the planarization layer.

The alignment layer is generally made of polyimide (abbreviated as PI), and the polyimide has fluidity before molding, so that when the material of the alignment layer is arranged on the planarization layer, a relatively large drop exists from the top of the planarization layer to the transparent substrate due to the fact that the planarization layer is not arranged in the hole region but only the transparent substrate of the array substrate is reserved, and the material of the alignment layer on the top of the planarization layer partially flows to the hole region, so that accumulation is formed at the bottom of the hole region, and further, in the subsequent solid-state call process, complete solidification is difficult due to the accumulation of the material of the alignment layer, and the alignment layer close to the bottom of the side wall of the planarization layer still has certain fluidity due to incomplete solidification.

In the subsequent use process of the display panel, for example, when the display panel is applied to a mobile phone, the display panel may frequently move along with the movement of the mobile phone, so that the material still having a certain fluidity overflows from the surface of the orientation layer, thereby affecting the propagation of light in the hole region, and even damaging other structures in the display panel.

Fig. 2 is a schematic cross-sectional view of a display panel shown in accordance with an embodiment of the present disclosure.

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

As shown in fig. 2, the display panel includes:

the display device comprises a display area and a blind hole which is arranged in the display area and is used for light to pass through;

the array substrate of the display panel is provided with a planarization layer, the side wall of the planarization layer facing the hole area comprises a plurality of descending edges, a connecting part between every two adjacent descending edges is parallel to the upper surface of the planarization layer, and the descending edges and the connecting part are in a step shape as a whole.

The number of falling edges may be set to 3 as shown in fig. 3, or other numbers of falling edges may be set as needed. The included angle between the descending edge and the connecting part can be set according to the requirement, the included angle can be a sharp angle or a round angle, and the included angle can be determined according to the manufacturing process.

It should be noted that the transparent substrate of the array substrate and the transparent substrate of the color filter substrate are disposed in the hole region, and other structures in the array substrate and the color filter substrate are not disposed, for example, structures such as a color filter and a black matrix in the color filter substrate are not disposed, and structures such as a thin film transistor, a gate line, and a data line in the array substrate are not disposed, so as to ensure that the hole region has high transparency. And the hole area can be further provided with structures such as a pixel electrode, a common electrode, an alignment layer, a polarizer and the like.

In one embodiment, when forming the alignment layer of the liquid crystal layer on the planarization layer, the material of the alignment layer may flow from the top of the planarization layer to the hole region along the sidewall of the planarization layer, and since the sidewall of the planarization layer is configured to include a plurality of falling edges, the connection between adjacent falling edges is relatively flat with respect to the falling edges, for example, the connection between adjacent falling edges is parallel to the upper surface of the planarization layer.

Therefore, the connection parts can generate larger resistance to the flow of the orientation layer relative to the descending edge, so that the material of the orientation layer is relatively uniformly retained on each connection part and is not accumulated on the bottom of the hole area in a large amount, the thickness of the orientation layer is relatively uniform, the orientation layer can be completely solidified in the subsequent solidification process, and the problem caused by incomplete solidification is avoided.

For example to avoid that material of the alignment layer overflows the surface of the alignment layer and affects the propagation of light in the area of the holes or damages other structures in the display panel.

And then when being applied to electronic equipment such as cell-phone with display panel, can set up the image acquisition equipment as leading camera in the hole region, and be located display panel and keep away from the one side of light-emitting direction to realized setting up image acquisition equipment under display panel, so that realize the full face screen.

And because the phenomenon that the light transmission in the hole area is influenced by the overflow of the material of the orientation layer from the surface of the orientation layer is avoided, the image acquisition equipment is favorable for ensuring that the image acquisition has a good effect.

As shown in fig. 2, in the display region, an array substrate is disposed below the liquid crystal layer, and the array substrate may include a planarization layer as shown in fig. 2, and may further include a gate insulating layer, a buffer layer, and other structures; in the color filter substrate not shown in fig. 2, a color filter, such as a red filter, a green filter, a blue filter, or a black matrix, may be disposed in the display region; and a touch sensor, such as a touch electrode, a photoelectric sensor with a touch function, an ultrasonic sensor, etc., may also be disposed on the display panel, which is not described herein again.

The embodiment is not only suitable for arranging the camera below the screen, but also can arrange other structures needing lighting, such as the optical sensor, in the hole area and on one side of the display panel far away from the light emitting direction, so that other lighting structures are arranged below the display panel.

Fig. 3 is a schematic cross-sectional view of another display panel shown in accordance with an embodiment of the present disclosure.

Optionally, as shown in fig. 3, the display panel may further include:

a light blocking region disposed between the display region and the hole region.

In one embodiment, the light-shielding region is opaque, and can block light in the display region from entering the aperture region, so as to avoid influencing an image acquired by the image acquisition device in the aperture region, and to be beneficial to ensuring that the image acquired by the image acquisition device has a good effect.

The light-shielding region may specifically include a light-shielding material disposed in the color film substrate, and the light-shielding material may be made of the same material as the black matrix in the color film substrate, so that the light-shielding material in the light-shielding region may be formed in the same process when the black matrix is formed, which is beneficial to simplifying the manufacturing process.

Fig. 4 is a schematic block diagram illustrating an electronic device in accordance with an embodiment of the present disclosure.

In an embodiment, an electronic device is taken as a mobile phone for example, a front camera needs to be arranged in the electronic device, then as shown in fig. 4, a blind hole is formed in the display panel in the above embodiment, a light shielding region is outside the hole region of the blind hole, and the front camera can be arranged in the hole region and located on one side of the display panel far away from the light emitting direction, so that the front camera does not need to be arranged on the front side of the mobile phone to reduce the screen occupation ratio, which is beneficial to realizing a full-screen.

The position where the blind hole is opened may be set according to the position of the front camera, for example, may be set at the upper right of the display panel as shown in fig. 4, or may be set at another position as needed.

Fig. 5 is a schematic block diagram illustrating another electronic device according to an embodiment of the present disclosure.

In an embodiment, a plurality of front-facing cameras, for example, two front-facing cameras, may also be disposed in the electronic device, and then, as shown in fig. 5, two blind holes may be opened on the display panel in the above-described embodiment.

Optionally, the sidewall of the planarization layer is located in the light-shielding region.

Because the side wall of the planarization layer comprises a plurality of descending edges and a connecting part is arranged between adjacent descending edges, although the planarization layer and the orientation layer can transmit light, the plurality of descending edges and the connecting part are not positioned on the same plane and still have certain influence on the propagation of light.

In one embodiment, as shown in fig. 3, the sidewall of the planarization layer may be located in the light-shielding region, and since the light-shielding region is opaque, the sidewall of the planarization layer is disposed in the light-shielding region, and even if the sidewall including the plurality of falling edges and the connecting portion 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 affecting the propagation of light in the hole region.

Optionally, the display panel further comprises:

and a spacer structure disposed in the liquid crystal layer of the light-shielding region.

In one embodiment, in order to ensure that light propagation in the hole region is not easily affected, the hole region may not be provided with a spacer structure, the light-shielding region may be provided along an edge of the hole region, and the spacer structure (provided on the color filter substrate and facing the array substrate) is provided 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 have a certain supporting effect on the cell thickness of the liquid crystal layer in the hole region.

It should be noted that the cell thickness of the liquid crystal layer supported in this embodiment is different from the cell thickness of the liquid crystal layer supported by the spacer structure in the related art.

Fig. 6 is a schematic view of a hole region in the related art. FIG. 7 is a schematic cross-sectional view AA' of the structure of FIG. 6.

As shown in fig. 6 and 7, 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 a spacer, 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 on the light transmission performance of the hole region, the spacer is not arranged in the liquid crystal layer in the hole region, and the cell thickness of the liquid crystal layer in the hole region is supported mainly by the spacer arranged in the light shielding region for the hole region.

Because no spacer column is arranged in the liquid crystal layer in the hole region, the spacer column arranged in the shading region outside the hole region can play a role of a fulcrum, so that a larger recess is generated on the surface of the liquid crystal layer in the hole region, and a display region outside the spacer region is warped to a certain extent, so that a structure similar to a concave lens is formed in the hole region, and the adverse effect is caused on the optical characteristic of an image collected by a lens below the hole region.

Based on the embodiment, since the sidewall of the planarization layer is located in the light-shielding region, a spacer structure is disposed in the liquid crystal layer in the light-shielding region, and at least a portion of the spacer structure may correspond to a surface of the sidewall of the planarization layer facing the color filter substrate.

Fig. 8 is a schematic cross-sectional view of yet another display panel shown in accordance with an embodiment of the present disclosure.

As shown in fig. 8 (where the orientation layer is not shown), the sidewall of the planarization layer includes 3 descending edges, where there are two connection portions B and C, and an upper surface a of the planarization layer, where a surface of the upper surface a of the planarization layer facing the color filter substrate corresponds to the spacer structure (e.g., spacer pillar) a, a surface of the connection portion B facing the color filter substrate corresponds to the spacer structure B, and a surface of the connection portion C facing the color filter substrate corresponds to the spacer structure C.

In the process of forming the array substrate and the color film substrate into the box, liquid crystal needs to be filled between the array substrate and the color film substrate, the distance between the array substrate and the color film substrate after forming the box is very close to that between the color film substrate and the color film substrate, so that the liquid crystal in a gap formed by the color film substrate and the array substrate generates a capillary phenomenon, and the liquid crystal can flow along the gap to enable the liquid crystal substrate and the color film substrate on two sides of the gap to be close to each other.

In the process of approaching the liquid crystal substrate and the color film substrate, a spacing structure closest to the planarization layer, for example, the spacing structure a first contacts with the upper surface a of the planarization layer, then the color film substrate and the array substrate do not approach each other, then the spacing structure B contacts with the connecting portion B, then the color film substrate and the array substrate do not approach each other, and finally the spacing structure C contacts with the connecting portion C, and then the color film substrate and the array substrate do not approach each other.

The distance between the upper surface A of the planarization layer and the interval structure a is the minimum, so that after the upper surface A of the planarization layer is contacted with the interval structure a, the deformation of the array substrate and the color film substrate is the minimum; the distance between the connecting part B and the spacing structure B is slightly larger, so that after the connecting part B is contacted with the spacing structure B, the deformation of the array substrate and the color film substrate is slightly larger; the distance between the connecting part C and the spacing structure C is the largest, so that after the connecting part C is contacted with the spacing structure C, the array substrate and the color film substrate are enabled to deform the largest.

This causes the liquid crystal layer between the array substrate and the color filter substrate to be bent in the light shielding region in the direction from the display region to the hole region. The liquid crystal layer is deformed because the surface of the liquid crystal layer has tension, but the tension of the surface of the liquid crystal layer is limited, the liquid crystal layer is bent outside the hole area, the bending generated inside the hole area is reduced, the curvature of the liquid crystal layer in the hole area is reduced, and the influence of the recess of the hole area on the image of the image acquisition device below the display panel is further reduced.

Optionally, the spacing structure is disposed corresponding to the connecting portion.

In one embodiment, the spacer structures may be disposed to correspond to the connection portions in their entirety, that is, in the region corresponding to the falling edge in the sidewall of the planarization layer, and no spacer structure is disposed, because even if the spacer pillars are disposed in this portion of the region, the spacer structures are difficult to stably contact with the falling edge to support the falling edge, and the spacer structures are disposed to correspond to the connection portions, so that the spacer structures can be stably contacted with the connection portions to effectively support the falling edge, and since the spacer structures do not need to be disposed in the region corresponding to the falling edge, the number of spacer pillars can be reduced on the basis of ensuring the support effect.

Optionally, the spacing structure comprises at least one of:

spacer columns and spacer balls.

Optionally, the spacer structure comprises a spacer, the spacer being an auxiliary spacer.

In one embodiment, the spacer pillars may be selected as a spacer structure to support the liquid crystal layer, and the spacer balls may be selected as a spacer structure to support the liquid crystal layer.

In the case of supporting the liquid crystal layer by using the spacers, the liquid crystal layer may be supported by using sub spacers (also referred to as sub spacers). The spacer columns comprise a main (main) spacer column and an auxiliary spacer column, wherein the main spacer column is longer than the auxiliary spacer column, and when the liquid crystal layer is not deformed, the main spacer column can support the cell thickness of the liquid crystal layer, which may cause the boundary between the hole region and the display region not to be deformed completely when being subjected to an external force, so that the technical effect in the embodiment shown in fig. 8 is difficult to achieve, and the auxiliary spacer column can support the cell thickness of the liquid crystal layer at the boundary on the basis of certain deformation when being extruded to a certain degree (for example, when contacting with a planarization layer as shown in fig. 8) when being subjected to an external force, so that the technical effect in the embodiment shown in fig. 6 is achieved.

In addition, in the liquid crystal layer of the display region, a spacer structure for supporting the cell thickness of the liquid crystal layer may be provided, and the spacer structure may include both the main spacer and the auxiliary spacer.

Optionally, the auxiliary spacers are disposed on a side of the liquid crystal layer close to a color film substrate in the display panel, and the height of each auxiliary spacer is equal.

In one embodiment, the heights of the auxiliary spacers in the light-shielding region may be set to be equal, so that in a process that the liquid crystal substrate and the color film substrate approach each other, the spacer structure closer to the planarization layer can contact the planarization layer first, and the spacer structure farther from the planarization layer and closer to the planarization layer can contact the planarization layer later, so as to ensure a liquid crystal layer between the array substrate and the color film substrate, and a bend exists in the light-shielding region from the display region to the hole region, so that in a position where the light-shielding region is closest to the hole region, the height of the surface of the liquid crystal layer is close to the height of the surface of the liquid crystal layer in the hole region, thereby ensuring that the deformation of the surface of the liquid crystal layer in.

An embodiment of the present disclosure further provides an electronic device including the display panel according to any one of the above embodiments.

The electronic device includes, but is not limited to, an electronic device such as a mobile phone, a tablet computer, a wearable device, and the like.

Optionally, the electronic device further comprises:

and the image acquisition equipment is arranged in the hole area and is positioned on one side of the display panel, which is far away from the light-emitting direction.

In one embodiment, the image capturing device disposed in the aperture region may refer to the entire image capturing device or a lens of the image capturing device.

The image acquisition equipment can be used as a front camera in electronic equipment. Through setting up image acquisition equipment in the hole region, and be located display panel and keep away from the one side of light-emitting direction, and need not to openly at electronic equipment with image acquisition equipment, be convenient for openly set up the display area that higher screen accounts for at electronic equipment, be favorable to realizing the full face screen based on liquid crystal display panel.

And based on the above embodiments, the alignment layer in the display panel can be completely cured, thereby avoiding problems due to incomplete curing. Therefore, the phenomenon that the light transmission in the hole area is influenced by the overflow of the material of the orientation layer from the surface of the orientation layer is avoided, and the good effect of image acquisition of the image acquisition equipment is ensured.
