The electrode structure lifted, but the same electrode structure using in adjustment pixel identical with the present invention realizes that penetrance is not in pixel
Same technical scheme is within the scope of this patent protection.
Inventor has found realize adjustment sub-pixel by adjusting electrode narrow slit angle or slit number in sub-pixel
Electric field intensity inside high size, and then realize that the brightness of adjustment low brightness pixel is less than the brightness of normal pixels.Inventor is narrow to electrode
Seam angle and the relation of slit number and penetrance have done analogue simulation experiment, l-G simulation test data result reference table 1.
The electrode narrow slit angle of table 1 and the relation of slit number and penetrance
Slot angles by 10 ° of works of slot angles with penetrance relation l-G simulation test, slit number in fixed electrode, joining
It is 100% than angle initialization penetrance, from data in table 1, slot angles more than or equal to 0 degree and are being less than or equal to 10 degree
In the range of when, with becoming larger for slot angles, penetrance becomes larger.In practice can be aobvious according to being pointed to by special-shaped border
Show that the different brightness in area direction need to design the size of slot angles in the electrodes of low brightness pixel and normal pixels.
Slit number using slit number as 3 with penetrance relation l-G simulation test, slot angles size in fixed electrode, being made
Reference sets penetrance as 100%, from data in table 1, slit number in the range of more than or equal to 1 and less than or equal to 3,
With increasing for slit number, penetrance becomes larger.Viewing area direction can be pointed to not according to by special-shaped border in practice
Same brightness needs, and with reference to electrode size in sub-pixel, designs slit in the electrode of low brightness pixel and normal pixels
Number.
Different slot angles can realize that 85%-100% brightness changes, and different slit numbers can realize brightness 50%-
40%-100% brightness change can be achieved in 100% change, the superposition of both slot angles and slit number, wherein, single sub-pixel
In, when slot angles are 10 degree and slit number is 3, penetrance is maximum；When slot angles are 0 degree and slit number is 1, penetrate
Rate is minimum.

Further, in some optional embodiments, Fig. 6 is special-shaped display panel provided in an embodiment of the present invention
The schematic top plan view of another optional embodiment, as shown in fig. 6, R angles are divided into the first tangent line Q1 by the angular bisector at R angles
For while first jiao of ∠ 1 and using the second tangent line Q2 as while second jiao of ∠ 2；First jiao of ∠ 1 angular bisector 11J is by first area
It is divided into the first subregion Z11 and the second subregion Z12 close to the first tangent line Q1 of the angular bisector J1 close to R angles, second
The picture that the pixel P adjacent with special-shaped border Y number is more than or equal in the first subregion Z11 in pixel groups in subregion Z12
The pixel P adjacent with special-shaped border Y number in plain group；Second area is divided into close by second jiao of ∠ 2 angular bisector 22J
In the angular bisector J1 at R angles the 3rd subregion Z23 and the 4th subregion Z24 close to the second tangent line Q2, the 4th subregion Z24
Pixel groups in the pixel P adjacent with special-shaped border Y number be more than or equal in the pixel groups in the 3rd subregion Z23 and abnormity
Pixel P adjacent border Y number.
In the embodiment, in order to adapt in first area arc border from the angular bisector J1 at R angles to end points direction
Trend, the pixel P adjacent with the special-shaped border Y number in pixel groups in the angular bisector J1 at R angles the first subregion Z11
The pixel P adjacent with special-shaped border Y less than in pixel groups in the second subregion Z12 number；In order to adapt to arc in second area
Shape border from R angles trend from angular bisector J1 to end points direction, in the 3rd subregion Z23 in pixel groups with special-shaped border Y phases
Adjacent pixel P number is less than pixel P adjacent with special-shaped border Y in the 4th subregion Z24 number, divides in the embodiment
The number of pixels adjacent with special-shaped border, has adapted to the trend on special-shaped border, has weakened special-shaped border in region design pixel groups
Crenellated phenomena is shown, the boundary shape showed during display is closer to arcuate shape；Second subregion Z12 and the 4th sub-district
Domain Z24 is respectively close to two end points on special-shaped border, and visually arc trend is than the first subregion Z11 and the 3rd subregion Z23
It is weak, more pixel can be set adjacent with special-shaped border.
Further, in some optional embodiments, as shown in fig. 6, in pixel groups in the first subregion Z11 with

Or the number equal to the low brightness pixel DP of the pixel groups in 2, second subregion Z12 is more than or equal to 2.
In the embodiment, in the pixel groups comprising low brightness pixel, the number of low brightness pixel is more than or waited
The number of pixels adjacent with special-shaped border in the pixel groups, reduces the luminance difference of viewing area and special-shaped border, weakens
Show crenellated phenomena.
Further, in some optional embodiments, as shown in fig. 6, the second subregion Z12 each pixel groups
In, the pixel P adjacent with special-shaped border Y number is equal with low brightness pixel DP number.In the pixel groups of the second subregion
In the pixel adjacent with special-shaped border number it is more, pixel all adjacent with special-shaped border is arranged to low-light level picture
Element, display crenellated phenomena is weakened, while is become larger by the brightness of low brightness pixel on the sensing viewing area direction of special-shaped border,
The even transition of brightness can be realized, the display effect of display panel is good.
Further, in some optional embodiments, different brightness in special-shaped display panel provided by the invention
The GTG differed between low brightness pixel is 16 integral multiple.
By most secretly having 0 to 255 totally 256 luminance levels, referred to as 256 ashes to most bright brightness change when display panel is shown
Rank, by adjusting electrode narrow slit angle and/or slit number in pixel in present embodiment, 14 GTGs differences have been pre-designed it
The low brightness pixel of 16 integral multiple, wherein, the minimum pixel of brightness is 15 GTGs in low brightness pixel, bright in low brightness pixel
The maximum pixel of degree is 239 GTGs, in the low-light level that the position adjacent with special-shaped border needs to set according to the selection of brightness demand
Pixel, now electrode narrow slit angle or slit number designed, save again carry out technological design time.Design
The integral multiple of GTG difference 32 then only needs to design 6 low brightness pixels, and the low brightness pixel number of different brightness is very few, it is impossible to
Meet the different brightness demands of special-shaped boundary neighboring pixels；Need design 30 low bright if the integral multiple of design GTG difference 8
Pixel is spent, the low brightness pixel number of different brightness is relatively more, and design is relative complex.14 kinds of differences are designed in present embodiment
The low brightness pixel of brightness, design is relatively easy, while can realize the more rich brightness change of low brightness pixel.
It should be noted that can be according to the low-light level of different brightness in different brightness Demand Design abnormity display panels
The grey decision-making differed between pixel, the GTG differed between the low brightness pixel of different brightness in above-described embodiment are 16 integer
Only it is again a kind of optional performance, is not the restriction to all situations in the present invention.
Further, the present invention also provides a kind of display device, including any one abnormity provided in an embodiment of the present invention
Display panel.Fig. 7 be display device provided in an embodiment of the present invention a kind of optional embodiment schematic top plan view, such as Fig. 7
