Description
[technical field]
The present invention relates to field of display technology, in particular to a kind of production method of color membrane substrates, color membrane substrates and liquid
LCD panel.
[background technique]
In the prior art, the principle of RGBW liquid crystal display technology be a kind of white (W) sub-pixel is dosed by red (R),
Green (G), blue (B) three colour cell at traditional rgb pixel in, then reapply corresponding sub-pixel imaging technique, seen with the mankind
The mode of image preferably arranges these sub-pixels.It just can ensure to generate what those cannot be seen by human eye in this way
When image, display screen power and intensity source will not be lost.RGBW sub-pixel imaging technique individually addresses for each sub-pixel, and
And a kind of white sub-pixels are added in pattern of rows and columns, a kind of RGBW pixel design is formed, which sets than traditional rgb pixel
The display screen of meter will more become clear and resolution ratio wants some higher.Because more backlights can pass through bigger and semi-transparent W picture
Element shines, rather than is blocked by the close-packed arrays that smaller red, green, blue sub-pixel that RGB stripe line uses is constituted, transmissivity and
Brightness is increased.Using white subpixel, the increase of white brightness is realized in the case where power consumption does not have increased situation.Cause
And the advantage of RGBW technology is the utilization rate of improving brightness of backlight source, saves power consumption, reduces cost, and do not reducing resolution ratio
Or in the case where increasing power consumption use, more levels of brightness is obtained.Therefore, RGBW liquid crystal display can more and more extensive use.
Referring to Fig. 1, being the structural schematic diagram for the color membrane substrates that the prior art provides, it can be seen that due to R, G, B
Pixel will use the color blocking of same thickness, and W sub-pixel does not have color blocking, so OC is covered on W after integrally coating one layer of OC
Sunk area will occur in pixel portion.Sunk area uneven surface can make in this way after carrying out friction treatment to oriented layer
There are the non-uniform phenomenons of friction orientation for oriented layer, and then will lead to leakage problem；Also, the uneven surface of oriented layer can also
The problems such as keeping the mobility for the liquid crystal molecule being in contact with oriented layer poor, and then pressing color difference can be generated.
