fig. 4 is a relative positional relationship diagram of the first electrode 11 and the second electrode 12 in the sub-pixel ZP1 in the conventional pixel PC according to an embodiment of the present invention, and fig. 5 is an AA' cross-sectional view of the embodiment in fig. 4, which only shows the relative positional relationship between the first electrode 11 and the second electrode 12 and the substrate 10, and does not show other film structures; fig. 6 is a diagram illustrating a relative position relationship between the first electrode 11 and the second electrode 12 in the sub-pixel ZP2 in the low-brightness pixel PD according to the embodiment of the present invention. Referring to fig. 4 to 6, the pixel includes at least three sub-pixels with different colors, each sub-pixel includes a first electrode 11 and a second electrode 12 disposed on the array substrate, and the second electrode 12 is disposed between the substrate 10 and the first electrode 11 along a direction perpendicular to a plane of the substrate 10; referring to fig. 4 and 6, the first electrode 11 includes a plurality of electrode strips 60 extending along a third direction and arranged along a fourth direction, a slit 61 is included between any two adjacent electrode strips 60, the third direction intersects with the fourth direction, the third direction is the same as or intersects with the second direction, and the fourth direction is the same as or intersects with the first direction; here, only the case where the third direction intersects the second direction and the fourth direction intersects the first direction will be described as an example. The second electrode 12 is typically a planar electrode which is arranged opposite the electrode strips 60 on the first electrode 11, and when a voltage is applied to the first electrode 11 and the second electrode 12, respectively, an electric field is formed between the first electrode 11 and the second electrode 12 which drives the liquid crystal to deflect. It should be noted that, in this application, the first electrode may be a pixel electrode and the second electrode is a common electrode, or the first electrode is a common electrode and the second electrode is a pixel electrode, which is not specifically limited in this application.
in particular, with continued reference to fig. 6, at least some of the sub-pixels ZP2 in the low-luminance pixel PD further include the auxiliary electrodes 20, in the pixel openings PK of the low-luminance pixel PD, the extending direction of the auxiliary electrodes 20 intersects with the extending direction of the electrode strips 60, and at least some of the auxiliary electrodes 20 are located in the slits 61 along the orthogonal projection perpendicular to the plane of the substrate; in this embodiment, the auxiliary electrode 20 whose extending direction intersects with the extending direction of the electrode bar 60 is introduced on the basis of the existing first electrode 11 and second electrode 12, so that the direction of the electric field formed at the auxiliary electrode 20 intersects with the direction of the electric field formed between the original first electrode 11 and second electrode 12, the electric field strength between the first electrode 11 and second electrode 12 is weakened, and the orthogonal projection of the auxiliary electrode 20 is located in the slit 61, and the path of the electric field penetrating from the position of the auxiliary electrode 20 into the liquid crystal cell is also blocked, so as to further weaken the electric field strength reaching the liquid crystal cell, reduce the rotation amplitude of the liquid crystal, further reduce the gray scale of the corresponding sub-pixel in the corresponding low-brightness pixel PD, and facilitate the special-shaped display panel 100 to meet the requirement of smaller gray scale transition, thereby further weakening the sawtooth phenomenon at the special-shaped boundary Y, and the display effect is improved.
alternatively, referring to fig. 7, fig. 7 is another relative position diagram of the first electrode 11 and the second electrode 12 in the sub-pixel provided in the embodiment of the present invention, and at least a part of the sub-pixel ZP2 in the low-luminance pixel PD further includes at least one electrode notch 40, and in the pixel opening PK of the low-luminance pixel PD, the electrode notch 40 is located on the first electrode 11 and/or the electrode notch 40 is located on the second electrode 12. The existence of electrode breach 40 has reduced first electrode 11 and second electrode 12 in the area of overlapping along the direction on the plane of perpendicular to substrate base plate place equivalently, the area of overlapping reduces, the electric field intensity that forms between first electrode 11 and the second electrode 12 will also reduce, can reduce the rotatory range of liquid crystal equally, thereby make the grey scale that corresponds the sub-pixel in the corresponding low-luminance pixel PD obtain further reduction, be favorable to adapting to the demand that the littleer grey scale of special-shaped display panel 100 transits, thereby further weaken the sawtooth phenomenon of special-shaped border Y department, promote display effect.
according to the application, the auxiliary electrode 20 or the electrode notch 40 is introduced into the pixel opening PK in at least part of the sub-pixels ZP2 corresponding to the low-brightness pixel PD, so that the electric field intensity in the corresponding pixel opening PK can be reduced, and the gray scale of the low-brightness pixel PD is further reduced on the premise of not further reducing the area of the pixel opening PK, so that the requirement of smaller gray scale transition of the special-shaped display panel 100 is favorably met.
It should be noted that, after the auxiliary electrode 20 or the electrode notch 40 is introduced into the pixel opening PK, the area occupied by the auxiliary electrode 20 or the electrode notch 40 in the pixel opening PK may be adjusted according to the actual gray scale requirement to realize the requirement of the low-brightness sub-pixel for the lower gray scale, for example, when the gray scale of the sub-pixel needs to be reduced from 61 to 30, the auxiliary electrode 20 or the electrode notch 40 with the first area may be introduced into the pixel opening PK; when the gray scale of another sub-pixel needs to be reduced from 61 to 20, the auxiliary electrode 20 or the electrode notch 40 with a second area can be introduced into the pixel opening PK, wherein the second area is larger than the first area, thereby being beneficial to realizing the fine setting of the lower gray scale of the low-brightness sub-pixel.
An embodiment in which the auxiliary electrode 20 is introduced in the low-luminance pixel PD will be described below.
in some alternative embodiments, with continuing reference to fig. 6, when at least some of the sub-pixels in the low-brightness pixel PD further include the auxiliary electrode 20, the auxiliary electrode 20 is on the same layer as the first electrode 11, the auxiliary electrode 20 includes at least one strip-shaped electrode 21, and the strip-shaped electrode 21 is connected to at least some of the electrode strips 60.
In this embodiment, when the auxiliary electrode 20 and the first electrode 11 are disposed on the same layer, the auxiliary electrode 20 and the first electrode 11 can be fabricated in the same mask process, so that a process of fabricating the auxiliary electrode 20 separately is omitted, and the improvement of the production efficiency of the special-shaped display panel 100 after the auxiliary electrode 20 is introduced is facilitated. In addition, because the width of the slit 61 between two adjacent electrode strips 60 in the first electrode 11 along the fourth direction is smaller, and the length along the third direction is larger, when the application connects the strip-shaped electrode 21 in the auxiliary electrode 20 with at least part of the electrode strips 60 in the first electrode 11, it is equivalent to increase the auxiliary electrode 20 in the slit 61 without considering the interval size of the auxiliary electrode 20 and the strip-shaped electrode 21 along the fourth direction, and different low gray scale design requirements can be realized by only adjusting the length of the auxiliary electrode 20 along the third direction, so that the method is also beneficial to reducing the process complexity for arranging the auxiliary electrode 20.
In some alternative embodiments, referring to fig. 6, the extending direction of the stripe electrodes 21 is parallel to the first direction, or referring to fig. 8, the extending direction of the stripe electrodes 21 is parallel to the fourth direction, where fig. 8 is another relative position relationship diagram of the first electrode 11 and the second electrode 12 in the sub-pixel provided in the embodiment of the present invention.

in order to realize the design of lower gray scale of the low-brightness sub-pixel, the strip-shaped electrode 21 can be arranged in the pixel opening PK, and the gray scale of the corresponding sub-pixel can be adjusted by adjusting the area of the strip-shaped electrode 21. In addition to this implementation, in some alternative embodiments, at least some of the sub-pixels in the low-luminance pixel PD include two strip-shaped electrodes 21; in this way, the ratio of the area of the strip-shaped electrodes 21 in the pixel openings PK can be changed by adjusting the number of the strip-shaped electrodes 21 in the pixel openings PK, and the design requirements of the low-brightness sub-pixels for different low gray levels can also be met.
Fig. 9 is a diagram illustrating another relative position relationship between the first electrode 11 and the second electrode 12 in the sub-pixel provided in the embodiment of the present invention, in which the extending directions of the two strip electrodes 21 are the same; thus, the two strip-shaped electrodes 21 can be manufactured by adopting the same specification process, which is beneficial to reducing the complexity of the manufacturing process;
Alternatively, fig. 10 is a diagram illustrating another relative position relationship between the first electrode 11 and the second electrode 12 in the sub-pixel provided in the embodiment of the present invention, when the fourth direction crosses the first direction, the extending direction of one of the two stripe electrodes 21 is parallel to the first direction, and the extending direction of the other is parallel to the fourth direction. By forming two strip-shaped electrodes 21 in the same sub-pixel in this way, the effects of weakening the electric field and reducing the gray scale can be achieved.
In some alternative embodiments, the same strip-shaped electrode 21 is connected to two electrode strips 60, respectively. Thus, when the strip-shaped electrodes 21 are disposed in the slits 61 formed by the two electrode strips 60, the strip-shaped electrodes 21 cover some regions of the slits 61 along the first direction or the fourth direction, that is, both sides of the strip-shaped electrodes 21 along the first direction or the fourth direction are connected to the electrode strips 60, and there is no need to consider a process of separating the strip-shaped electrodes 21 from the electrode strips 60 by a distance along the first direction or the fourth direction, which is beneficial to reducing a manufacturing process of manufacturing the strip-shaped electrodes 21.
In some optional embodiments, referring to fig. 8-10, the orthographic projection of the auxiliary electrode 20 on the plane of the substrate is completely located in the pixel opening PK, at this time, the area of the auxiliary electrode 20 in the pixel opening PK is equal to the actual area of the auxiliary electrode 20, and the gray scale of the corresponding sub-pixel can be controlled by controlling the actual area of the auxiliary electrode 20.
alternatively, in some optional embodiments, fig. 11 is a diagram illustrating another relative position relationship between the first electrode 11 and the second electrode 12 in the sub-pixel provided in an embodiment of the present invention, in which a part of the orthogonal projection of the auxiliary electrode 20 on the plane of the substrate is located in the pixel opening PK, and another part of the orthogonal projection is located outside the pixel opening PK. At this time, the area of the portion of the auxiliary electrode 20 in the pixel opening PK is smaller than the actual area of the auxiliary electrode 20, and the gray scale of the corresponding sub-pixel can be controlled by controlling the size of the area of the portion of the auxiliary electrode 20 in the pixel opening PK.
An example of introducing the electrode notch 40 in the low-luminance pixel PD will be described below.
in some alternative embodiments, fig. 12 is a diagram illustrating another relative position relationship between the first electrode 11 and the second electrode 12 in the sub-pixel provided in the embodiment of the present invention, when the electrode notch 40 is located on the first electrode 11, the notch penetrates at least a portion of the electrode stripe 60 in the pixel opening PK of the low-brightness pixel PD.
In this embodiment, the area of the first electrode 11 in the sub-pixel opening PK is reduced, so that the overlapping area of the first electrode 11 and the second electrode 12 in the direction perpendicular to the plane of the substrate is reduced, the electric field intensity formed between the first electrode 11 and the second electrode 12 is reduced, the liquid crystal deflection amplitude is reduced, and the gray scale of the corresponding sub-pixel is reduced. It should be noted that the electrode notch 40 may be formed at the same time when the first electrode 11 is formed, for example, the first electrode 11 and the electrode notch 40 are formed simultaneously in a mask process, which is advantageous to simplify the manufacturing process and improve the production efficiency. Of course, the electrode gap 40 may be formed by etching a partial region of the electrode bar 60 after the electrode bar 60 is formed. This is not particularly limited in the present application. The present application can also achieve the different low gray level requirements in the low brightness pixel PD by adjusting the area of the electrode bar 60 gap in the pixel opening PK, for example, when the required gray level is lower, the area of the portion of the electrode gap 40 in the pixel opening PK can be designed to be larger, otherwise, the area can be designed to be smaller. Fig. 11 shows the case where the electrode gap 40 penetrates through the electrode bar 60, but of course, in some other embodiments of the present application, the electrode gap 40 need not penetrate through the electrode bar 60 as long as the area of the electrode gap 40 in the pixel opening PK meets the size requirement.
In some alternative embodiments, fig. 13 is a diagram illustrating another relative position relationship between the first electrode 11 and the second electrode 12 in the sub-pixel provided in the embodiment of the present invention, when the electrode notch 40 is located on the second electrode 12, the notch extends along the first direction (as shown in fig. 13) or along the fourth direction (as shown in fig. 7) in the pixel opening PK of the low-brightness pixel PD;
in the pixel aperture PK of the low brightness pixel PD, the electrode indentation 40 and at least part of the electrode stripe 60 overlap in a forward projection onto the plane of the substrate base plate.
in the embodiment shown in fig. 7 and 13, the electrode notches 40 are formed on the second electrode 12, and the electrode notches 40 and the electrode bars 60 overlap with each other in the orthogonal projection direction of the substrate, which is equivalent to reducing the overlapping area of the second electrode 12 and the first electrode 11 in the pixel opening PK along the direction perpendicular to the substrate, thereby also being beneficial to reducing the electric field strength formed between the first electrode 11 and the second electrode 12, reducing the liquid crystal deflection amplitude, reducing the gray scale of the corresponding sub-pixel, and further meeting the transition requirement of the low-brightness sub-pixel for lower gray scale.
in some alternative embodiments, fig. 14 is a schematic diagram of the hollow portion 41 on the first electrode 11, and fig. 15 is a schematic diagram of the hollow portion 41 on the second electrode 12, when the electrode gap 40 is located on the first electrode 11 and/or the electrode gap 40 is located on the second electrode 12, the electrode gap 40 includes the hollow portion 41 penetrating through the first electrode 11 and/or the second electrode 12 along a direction perpendicular to a plane of the substrate.
In the pixel opening PK, the hollow portion 41 may be located on only one of the first electrode 11 or the second electrode 12, or the hollow portions 41 may be disposed on both the first electrode 11 and the second electrode 12, please refer to fig. 14 and fig. 15, and the specific number, size and position of the arrangement may be determined according to the requirement of the sub-pixel on the gray scale. When the electrode gap 40 includes the hollow portion 41, the introduction of the hollow portion 41 can also weaken the electric field intensity between the first electrode 11 and the second electrode 12, thereby realizing a lower gray scale design of the sub-pixel.
In some alternative embodiments, the shape of the orthogonal projection of the hollow portion 41 on the plane of the substrate base plate is a circle or a polygon. For example, the hollow portion 41 shown in fig. 14 is a circle or an ellipse, and the hollow portion 41 shown in fig. 15 is a polygon, but the shape of the hollow portion 41 may be flexibly set according to actual requirements, and the present application is not particularly limited thereto.
In some alternative embodiments, fig. 16 is a schematic diagram of a part of pixels of the profiled display panel 100 provided in the present application, where the low-luminance pixel PD includes a first low-luminance pixel PD1 and a second low-luminance pixel PD2, the first low-luminance pixel PD1 is adjacent to the profiled boundary Y, the second low-luminance pixel PD2 is located on a side of the first low-luminance pixel PD1 away from the profiled boundary Y, and the sub-pixels in the first low-luminance pixel PD1 include the auxiliary electrode 20 or the electrode notch 40 in the foregoing embodiments.
In an actual manufacturing process, the opening area of the first low-luminance pixel PD1 may be designed to be equal to the opening area of the second low-luminance pixel PD2, for example, each opening area is designed to be 8 μm by 8 μm, but since the first low-luminance pixel PD1 is closer to the irregular boundary Y, it is more beneficial to realize the transition of edge luminance and weaken the jaggy phenomenon when the gray scale of the first low-luminance pixel is designed to be smaller than that of the second low-luminance pixel PD 2. At this time, on the premise that the opening area of the sub-pixel in the first low-luminance pixel PD1 is not changed, the auxiliary electrode 20 or the electrode notch 40 may be respectively disposed in each sub-pixel corresponding to the first low-luminance pixel PD1, so as to weaken the electric field intensity in the sub-pixel corresponding to the first low-luminance pixel, so that the gray scales of the sub-pixels are smaller than the gray scale of the sub-pixel corresponding to the second low-luminance pixel PD2, for example, when the gray scale of the second low-luminance sub-pixel is 61, the gray scale of the first low-luminance pixel PD1 may be reduced to be less than 61 by introducing the auxiliary electrode 20 or the electrode notch 40, so that a better luminance transition is realized at the irregular boundary Y, which is more favorable for weakening the saw tooth phenomenon, and improving the visual experience effect.
In the above embodiment, the auxiliary electrode 20 or the electrode notch 40 is disposed in the first low-luminance pixel PD1 adjacent to the irregular boundary Y, and in some alternative embodiments, fig. 17 is a schematic diagram of a part of pixels of the irregular display panel 100 provided in the present application, and at least a part of the sub-pixels in the second low-luminance pixel PD2 include the auxiliary electrode 20 or the electrode notch 40.
When a more refined low-gray level transition is required at the special-shaped boundary Y of the display panel, for example, sub-pixels in several consecutive pixels at the special-shaped boundary Y are required to be designed to have a gray level lower than 61 (for example, the first low-brightness pixel PD1 and the second low-brightness pixel PD2 are required to have a lower gray level), the part of pixels includes both the first low-brightness pixel PD1 adjacent to the special-shaped boundary Y and at least one second low-brightness pixel PD2 not adjacent to the special-shaped boundary Y, when the gray scale cannot be reduced by changing the area of the pixel opening PK in the process, the design of lower gray scale can also be realized by disposing the auxiliary electrode 20 or the electrode notch 40 in each second low-brightness pixel PD2, for example, the gray levels are sequentially represented as 15, 31, 48, and the like, so that a finer brightness transition effect is realized, and the visual experience effect is more favorably improved.
based on the same inventive concept, the present application further provides a display device 300 including any one of the special-shaped display panels 100 provided in the embodiments of the present application.

In particular, the present application introduces auxiliary electrodes or electrode gaps in at least some of the sub-pixels in the low brightness pixels:
when the auxiliary electrode is introduced, in the pixel opening of the low-brightness pixel, the extending direction of the auxiliary electrode is crossed with the extending direction of the electrode strip in the corresponding sub-pixel, so that the electric field direction formed at the position of the auxiliary electrode is crossed with the electric field direction formed at the position of the electrode strip, meanwhile, the auxiliary electrode is positioned in the slit, and the effect of blocking the electric field at the position of the auxiliary electrode is also achieved.
When the electrode notch is introduced into the sub-pixel opening, in the pixel opening of the low-brightness pixel, the existence of the electrode notch is equivalent to the reduction of the overlapping area of the first electrode and the second electrode in the direction perpendicular to the plane of the substrate base plate, the overlapping area is reduced, the electric field intensity formed between the first electrode and the second electrode is also reduced, the rotation amplitude of the liquid crystal can be reduced, the gray scale corresponding to the sub-pixel in the corresponding low-brightness pixel is further reduced, the requirement of adapting to the smaller gray scale transition of the special-shaped display panel is facilitated, the sawtooth phenomenon at the special-shaped boundary is further weakened, and the display effect is improved.
