Specific embodiment
With reference to the accompanying drawing, technical solution of the present invention is specifically described.
The present invention provides a kind of method for cutting edge of the pixel scrap region of abnormity cutting display panel, to pixel trimming area
When domain carries out trimming, so that the elemental area of pixel scrap region is greater than the pixel faces positioned at pixel scrap region interior zone
Product.This method can be applied to LCD, in OLED display panel.
The aperture opening ratio of the pixel scrap region is greater than the aperture opening ratio of pixel scrap region interior zone.
Each color colored filter size of RGB of the pixel scrap region collocation is according to pixel scrap region pixel RGB
Each color sub-pixels area adjusts accordingly, and each color colorized optical filtering chip size of RGB of pixel scrap region collocation is greater than
Each color colorized optical filtering chip size of RGB of pixel scrap region interior zone collocation.
When this method is applied in OLED display panel, the fine metal mask plate of the pixel scrap region collocation is opened up
Hole adjusted accordingly according to the aperture opening ratio of pixel scrap region, and pixel scrap region collocation fine metal mask plate
The bore hole size opened up is greater than the hole that the fine metal mask plate of pixel scrap region interior zone collocation opens up.
When this method is applied in OLED display panel, the blue subpixels of the pixel scrap region are located most closely to picture
At plain scrap region interior zone.
Each color sub-pixels aperture opening ratio of the RGB of the pixel scrap region is consistent.
Each color sub-pixels aperture opening ratio of the RGB of the pixel scrap region is determined with minimum color sub-pixels aperture opening ratio.
The following are specific implementation processes of the invention.
The method for cutting edge of the pixel scrap region of abnormity cutting display panel of the invention (it is aobvious to can be applied to LCD, OLED
Show in panel), it is implemented as follows:
(1) scrap region pixel is big compared with the inside pixel, therefore pixel is not identical big inside effective indication range in panel
It is small.
(2) liquid crystal display processing procedure-scrap region pixel is different compared with the colored filter collocation of the inside pixel, scrap region
Each color area of the colored filter RGB of the big collocation of pixel aperture ratio area is with regard to larger, the small collocation of the inside pixel aperture ratio area
Each color area of colored filter RGB it is just smaller, so the colored filter RGB on panel is not that identical area is big
It is small.
(3) when this method is applied in OLED display panel, organic light emitting diode processing procedure-scrap region fine metal is covered
Diaphragm plate vapor deposition it is different from the inside pixel, the hole of the fine metal mask plate of the big collocation of scrap region pixel aperture ratio area it is wide open compared with
Greatly, the hole of the fine metal mask plate of the small collocation of the inside pixel aperture ratio area is wide open smaller, so FMM is not identical
Hole size.
(4) when this method is applied in OLED display panel, by the sub- picture of blue in the RGB pixel of organic light emitting diode
Element arranges the most inner side of scrap region.(OLED is to cut because blue subpixels luminous efficiency is worst being located most closely to pixel
At border region interior zone, LCD is not intended to limit the arrangement of light emitting pixel)
In addition, also needing each color sub-pixels aperture opening ratio of RGB of adjustment scrap region approximate consistent.The RGB aperture opening ratio of trimming pixel
It is determined by minimum color aperture opening ratio (R).The pixel aperture ratio area of another two colors (B, G) cooperates minimum color (R) aperture opening ratio.
Above as shown in figure 3, first 3 points are the optimal luminescent area collocation in order to which light emission luminance, coloration can be consistent in mating surface
Consider；4th organic light emitting diode blue light efficiency is worst, and trimming most inner side open area can be maximum, facilitates adjustment brightness, color
Degree considers.
The present invention increases the sub-pixel space of trimming, and it is identical with pixel inside display to strive for light-emitting area, and makes to shine
Bright chroma is identical.Solve that trimming RGB sub-pixel can be cut it is inconsistent cause sub-pixel for emitting light area too small, and make edge
Bright chroma is wrong.
Fig. 4 is the method for cutting edge of the pixel scrap region of an example abnormity cutting display panel.As shown in figure 4, trimming area
Domain pixel and the inside pixel size are inconsistent.Advantage color is correct, brightness is correct, the careful difference of disadvantage trimming pixel screen.
Fig. 5 is the method for cutting edge of the pixel scrap region of another example abnormity cutting display panel.As shown in figure 5, trimming
Area pixel is identical as the inside pixel size.Advantage color is correct, picture is careful good, and disadvantage trimming pixel intensity, which can be experienced, to be fallen
Difference.
The above are preferred embodiments of the present invention, all any changes made according to the technical solution of the present invention, and generated function is made
When with range without departing from technical solution of the present invention, all belong to the scope of protection of the present invention.
