Detailed Description

Features and exemplary embodiments of various aspects of the present application are described in detail below to make the objects, technical solutions and advantages of the present application more apparent, and to further describe the present application in conjunction with the accompanying drawings and the detailed embodiments. It should be understood that the specific embodiments described herein are merely configured to explain the present application and are not configured to limit the present application. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by showing examples of the present application.

It is noted that relational terms such as first and second, and the like are used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.

It will be understood that when a layer, an area, or a structure is described as being "on" or "over" another layer, another area, it can be referred to as being directly on the other layer, another area, or another layer or area can be included between the layer and the other layer, another area. And if the component is turned over, that layer, one region, will be "under" or "beneath" the other layer, another region.

Referring to fig. 1 and 2, fig. 1 is a schematic plan view of a display panel according to an embodiment of the present application, fig. 2 is a schematic partial pixel arrangement diagram of a liquid crystal display panel in the prior art, and fig. 3 is a schematic cross-sectional view along a line A-A of fig. 2.

In the prior art, in order to realize the under-screen image capturing effect of the liquid crystal display panel, a part of the liquid crystal display panel is generally set as a transparent area AB1, the transparent area AB1 includes a substrate 01, a color film substrate 02, liquid crystal molecules and other components, a light sensing element such as an image capturing component (not shown in the figure) is further disposed at one side of the transparent area AB1 far away from the color film substrate 02, and external light can pass through a film layer structure in the transparent area to be captured by the image capturing component, so as to realize the under-screen image capturing operation.

Illustratively, a plurality of pixel units 011 are disposed within the substrate base 01, the pixel units 011 including pixel electrodes and common electrodes. Specifically, when the liquid crystal display panel performs image capturing, the pixel electrode in the transparent area AB1 receives a driving voltage, the liquid crystal molecules rotate under the action of an electric field formed by the pixel electrode and the common electrode, and external light enters the image capturing assembly through the liquid crystal molecules, so that the image capturing work is completed. However, in practical use, the inventors have found that the arrangement of projections on the substrate 01 is regular on the peripheral side of the pixel unit in the transparent region, such as the scanning line NG, the data line ND, and other signal lines that can be used for transmitting the driving signal. After the external light enters, obvious diffraction phenomenon is easy to generate. After the electrodes are electrified, the liquid crystal molecules can obviously enhance the passing ability of external light under the action of an electric field formed by the electrodes, so that the diffraction phenomenon is more obvious.

In order to solve the above-mentioned problems, referring to fig. 1 to 4, fig. 4 is a schematic diagram of pixel arrangement in a first display area according to an embodiment of the present application. Some embodiments of the present application provide a display panel including a display area AA and a non-display area BB at least partially surrounding the display area AA, the display area AA including a first display area AA1 and a second display area AA2 at least partially surrounding the first display area AA 1.

The display panel includes: a substrate base 01, sub-pixels and signal lines N on the substrate base 01; the sub-pixels in the first display area AA1 are first sub-pixels 11, and the first sub-pixels 11 include a white sub-pixel W and a color sub-pixel Y; the first signal line N1 is arranged around the white subpixel W in the signal line N; the edge of the first signal line N1 between adjacent first sub-pixels 11, which is orthographically projected on the substrate 01, includes a first curved edge N11.

It is known that light travels through obstacles such as slits, holes, or discs, bending to varying degrees, and thus deviates from the original straight path of travel, i.e., diffracts; the distribution of the diffraction fringes is affected by the width of a slit, the size of a small hole and the like, and the positions of diffraction fringes generated by regular lines with equal widths are consistent, so that more obvious diffraction effects can appear after superposition. According to the scheme provided by the embodiment of the application, the first signal line N1 is set to be in the curve shape, so that excessive regular-shape patterns can be prevented from being formed in the first display area AA1, and the diffraction superposition is prevented from generating to form an obvious diffraction effect. And secondly, diffraction fringes in different positions and directions can be generated by the curved design of the first signal line N1, so that the generated diffraction fringes are mutually offset, the diffraction phenomenon is reduced, and the interference of the diffraction fringes on the imaging effect is further reduced.

In the field of under-screen photographing, external light needs to pass through multi-layer structures such as a color film substrate and a substrate to enter the photographing assembly, light loss in a transmission path is large, so that an imaging display effect is poor, and in order to improve the imaging display effect, white sub-pixels with larger area occupation in a first display area can be lightened in an auxiliary mode when photographing so as to enlarge the external light entering the photographing assembly, and further a better imaging display effect is obtained, however, the light quantity passing through the white sub-pixels and the periphery of the white sub-pixels is increased, and the number of signal lines on the periphery of the white sub-pixels is large, so that diffraction problems are remarkably aggravated, such as bright cross stars. At this time, the first signal line on the periphery of the white sub-pixel is bent, so that the diffraction problem can be effectively reduced, and the imaging display effect can be improved.

Specifically, the plurality of signal lines N are arranged in a staggered manner (in a checkerboard shape) in a plan view, and the plurality of regions are defined, and the first sub-pixels 11 are correspondingly arranged in the regions, so the first signal lines N1 surrounding the white sub-pixels W may be the signal lines that define the regions where the white sub-pixels W are located, or may be other signal lines N in the regions where the white sub-pixels W are located, such as TFTs (thin film transistors, thin Film Transistor) connected to the white sub-pixels W, and the like, and the present embodiment is not particularly limited. In particular, the color sub-pixel Y may be a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B. Specifically, the first curved edge N11 may be a major arc, a minor arc, a wave, etc., the major arc is an arc greater than a semicircle, the minor arc is an arc less than a semicircle, and the specific curved edge may be arbitrarily designed, which is not specifically limited herein. The number of diffraction fringes can be obviously reduced by the arc-shaped edge, diffraction phenomenon during imaging is improved, and imaging quality is improved; the wavy edges generate more diffraction fringes, so that the mutually offset diffraction fringes are more, namely, the diffraction phenomenon during imaging is weaker, and the imaging quality is further improved.

It is to be understood that the shape of the first display area AA1 is only schematically shown in this embodiment, and in a specific implementation, the shape of the first display area AA1 may be set to any shape, such as a rounded rectangle, a circle, a drop shape, and the like. In practical applications, the shape of the first display area AA1 is designed according to the structure of the light-sensitive element disposed in the first display area AA1, which is not limited herein.

In some embodiments of the present application, please refer to fig. 5 in combination, fig. 5 is a schematic diagram of pixel arrangement in a first display area according to another embodiment of the present application. The signal lines N further include second signal lines N2 disposed around the peripheral side of the color sub-pixels Y, and the edges of the second signal lines N2 projected on the substrate 01 include second curved edges N21.

Based on the principle that the enhancement imaging effect of the white sub-pixel is the same, the color sub-pixel can be further lightened, the amount of external light entering the imaging component is increased, the vividness of imaging display is improved, at the moment, the second signal line on the peripheral side of the color sub-pixel is bent, and the situation that the diffraction problem caused by the fact that the color sub-pixel is lightened is effectively reduced.

Specifically, the second curved edge N21 may be a major arc, a minor arc, a wavy shape, or the like. The specific arcuate edge may be any design and the present embodiment is not specifically limited herein. The number of diffraction fringes is obviously reduced by the arc-shaped edge, diffraction phenomenon during imaging is improved, and imaging quality is improved; the wavy edges generate more diffraction fringes, so that the mutually offset diffraction fringes are more, namely, the diffraction phenomenon during imaging is weaker, and the imaging quality is further improved.

In some embodiments of the present application, please refer to fig. 6 and fig. 7 in combination, fig. 6 is a schematic diagram of pixel arrangement in the first display area provided in yet another embodiment of the present application, and fig. 7 is a schematic cross-sectional view of fig. 6 along a line B-B. The white subpixel W comprises a first electrode 12, and the edge of the first electrode 12 projected on the substrate 01 comprises a third curvilinear edge 121.

By setting the edges of the first electrodes 12 to be curved, it is possible to reduce the formation of significant slits between the first electrodes 12 and the signal lines N on the peripheral side, reduce the occurrence of diffraction, and effectively reduce the formation of regular gaps of equal width between the plurality of first electrodes 12 arranged in an array and the signal lines N, preventing diffraction from overlapping, and forming a more significant diffraction effect.

Specifically, in this embodiment of the present application, the display panel further includes an electrode layer a and an electrode layer B located on the substrate 01, where the electrode layer a is located on a side of the substrate 01 facing the light emitting surface of the display panel, and the electrode layer B is located on a side of the electrode layer a away from the substrate 01, where the substrate 01 is used to bear each film structure of the display panel, the electrode layer a is used to manufacture the first electrode 121 of the first sub-pixel 11, and the electrode layer B is used to manufacture a common electrode (not shown in the drawing) corresponding to the first electrode 121, where the first electrode 121 and the common electrode that are oppositely arranged are insulated from each other.

Specifically, referring to fig. 8, fig. 8 is a partial enlarged view of a white sub-pixel in a first display area according to an embodiment of the present application. The third curvilinear edge 121 can be arcuate, such as a major arc, a minor arc, a wavy shape, and the like. Without limitation, the specific edge of the third curved edge 121 may be arbitrarily designed, and the present embodiment is not specifically limited herein. For example, the bending tendency of the third curved edge 121 is similar to that of the first curved edge N11 or the second curved edge N21, and if the first curved edge N11 at the corresponding position is a convex curve, the third curved edge 121 is also a convex curve, and the convex degree is similar to that of the first curved edge N11, preferably the same. By arranging the third curve edge 121 in coincidence with the first curve edge N11 or the second curve edge N21, a larger area occupation ratio of the white sub-pixel and the color sub-pixel can be obtained, and diffraction generated by the curve structure which is arranged in a converging manner diverges towards the periphery, so that obvious superposition diffraction problem can not be formed.

In some embodiments of the present application, please refer to fig. 6 in combination. The color sub-pixel Y comprises a second electrode 13, and the edge of the second electrode 13 projected on the substrate 01 comprises a fourth curved edge 131.

The fourth curvilinear edge 131 can be arcuate, such as a major arc, a minor arc, a wavy shape, and the like. However, the specific edge of the fourth curved edge 131 may be arbitrarily designed, and the present embodiment is not specifically limited herein. For example, the bending tendency of the fourth curved edge 131 is similar to that of the first curved edge N11 or the second curved edge N21, and if the first curved edge N11 at the corresponding position is a concave curve, the fourth curved edge 131 is also a concave curve, and the concave degree is similar to that of the first curved edge N11, preferably the same.

Specifically, the passivation layer is silicon nitride. Specifically, the passivation layer is disposed between the electrode layer a and the electrode layer B, and can relatively insulate the electrode layer a and the electrode layer B from each other.

By adding the passivation layer 03 with the refractive index similar to that of the first electrode 12 and the second electrode 13 on the electrode layer a, obvious deviation of the light path irradiated by external light caused by refractive index conversion can be prevented, and the diffraction condition is aggravated.
