Description
Technical field
The utility model relates to technical field of liquid crystal display, specifically, it relates to color membrane substrates, liquid crystal panel and display unit that a kind of new pixel (also referred to as drawing element) designs.
Background technology
In field of liquid crystal display, include multiple spectral filter. Wherein, colored filter (Colorfilter, having another name called color film) purposes comprises by selecting look passband and LCD (LiquidCrystalDisplay, liquid-crystal display) peak power output to monochrome display (such as VF (VacuumFluorescent, vacuum fluorescent display), EL (Electroluminescent, electric glimmering active display), LED (light emitting diode indicator) etc.) carry out contrast enhancing; Broad band pass filter is used for improving contrast and the performance of optical scanner and light emitting diode indicator red, yellow, amber; Midst density three grooved spectral filter and polarizer by reducing internal reflection and produce a bigger variable between indicating meter output rating and background thus strengthen the contrast of LCD.
As shown in Figure 1, LCD is the assembly of non-active luminescence, it generally comprises colored filter 1, liquid crystal panel 2, TFT element 3 and backlight module 4, the display of its color the backlight module 4 (such as penetrating type LCD) of transmission display device inside or the ambient incident light (such as reflection-type or semi penetration type LCD) of outside must provide light source, collocation drives IC (DriveIC again, driving chip) form ash rank display (GrayScale) with the control of liquid crystal panel 2, the RGB then passing through colored filter 1 is (wherein, R is red, G is green, B is blue, Fig. 1 does not show corresponding color) color layer offer form and aspect (Chromacity), form colored display frame (is the colored display frame formed in conjunction with RGB color layer herein, Fig. 1 does not illustrate corresponding color).
As shown in Figure 2, in order to promote the panel luminance of LCD, usually can improve in the structure of color film, wherein have a kind of technology improving color membrane structure to be called as RGBW technology. For original display screen, corresponding three pixels of pixel, i.e. corresponding RGB tri-pixel of independent pixel. And the meaning of RGBW is exactly outside R (redness), G (green), B (blueness) three pixels, increase the pixel W of a transparent color (WhitePixel), two independent pixels are allowed to share five pixels, like this when same resolving power, the quantity of secondary pixel obviously reduces, thus has saved many costs. The increase of W pixel, it is also possible to promote the brightness of screen, but shortcoming is in the optimization of color, it is possible to do not have the arrangement mode of RGB originally good.
As shown in Figure 1, traditional pixel is made up of R, G and B. The pixel of FHD (2K �� 1K) panel is 1920 �� 1080, and often kind of pixel forms (R, G, B) by three sub pixels, and therefore it one has 6,200,000 kinds of colors. And the resolving power of UHD (4K) panel has 3840 �� 2160, this represents that it has 2,490 ten thousand kinds of colors (3840 �� 2160 kinds of pixels, often kind of pixel is made up of) three sub pixels. Therefore, the resolving power of UHD panel is four times of FHD panel.
Although the principle of display is identical, but RGBW panel is slightly different with tradition UHD television panels, and RGBW panel, except RGB, also add W sub-pixel in pixel. In simple terms, the pixel count of each horizontal scanning linear of UHD panel is the number of sub-pixels under 3840, RGB framework is 11520; As for RGBW panel, because being that RGBW forms 1 pixel by 4 sub-pixels, therefore the real pixel number of every bar horizontal sweep line is only left 2880, and Vertical number of pixels is still 2160, identical with the UHD panel of RGB arrangement.
In addition, many companies, in order to improve image quality, also have employed GMA (colour gamut reflection algorithm) and SPR (sub-pixel is played up) technology in its RGBW panel.
Fig. 3 is the schematic diagram of the flow process of existing RGBW fabrication techniques color membrane substrates, wherein each square frame represents corresponding making step, the other figure of square frame then represents the structure of the color membrane substrates that corresponding step is formed, and both combine and can more clearly illustrate the making processes of color membrane substrates. As can be seen from Figure 3, RGBW technology is conducive to improving image quality, but because of its many W transparent color pixel, needs the Making programme of many one transparent optical resistances accordingly again. Fig. 4 is the color membrane substrates that the RGBW according to Fig. 3 completes, because many one W transparent color Making programme (comprising micro-shadow/development/hardening etc.), the cost of manufacture of whole color film is many 12%, seriously affects the popularization of RGBW technology. Wherein, the composition of each several part in the structure of the color membrane substrates of Fig. 3 and Fig. 4 can with reference to the Reference numeral in figure 7.
Fig. 5 illustrates another kind of color membrane substrates, it is in order to reduce the Making programme of one W transparent color, in the Making programme of flat bed (OverCoat), the material of flat bed is used to replace the making processes of W transparent color, make color membrane substrates both have flat bed function with this, have again transparent pixels structure. But, the shortcoming of this technology is because transparent pixels position does not have the covering that can support flat bed in picture RGB color layer (ColorLayer), the flat bed of transparent pixels position is caused to have depression, and the section difference of depression is the h of signal in figure, the value of h may be greater than 0.2um, like this then cell-gap inequality 14 (Cellgapmura) as shown in Figure 6 can be produced, then have after lighting panel that ash rank are uneven, the phenomenon of brightness irregularities.
