Background technology
Along with the development of display technique and social progress, liquid crystal display is applied by people more and more widely, plays vital effect in commercial production, people's lives.
Liquid crystal display (Liquid Crystal Display is called for short LCD) has the features such as volume is little, low in energy consumption, radiationless, has obtained in recent years developing by leaps and bounds, and in current flat panel display market, has occupied leading position.At present, LCD is widely used on various big-and-middle undersized products, almost contain the main electronic product of current information society, as LCD TV, high definition digital television, computer (desk-top and notebook), mobile phone, PDA, GPS, car-mounted display, Projection Display, video camera, digital camera, accutron, counter, electronic instrument and meter, public demonstration and illusory demonstration etc., be that current any traditional display modes cannot be reached.
But because liquid crystal material itself can not be luminous, LCD is a kind of passive display device, need to could realize by means of external light source the demonstration of certain brightness and color.Classify according to the mode of utilizing external light source, LCD generally comprises reflection type LCD (Reflective LCD, be called for short RE-LCD), transmission-type LCD(Transmissive LCD, be called for short TS-LCD) and Transflective LCD(Transflective LCD, be called for short TR-LCD).TR-LCD can adopt the display mode of RE-LCD in the sufficient situation of ambient light, has both overcome TS-LCD and under high light, has shown fuzzy defect, has reduced again power consumption; And in dark surrounds situation, can light backlightly, and adopt TS-LCD display mode, overcome the defect that RE-LCD cannot show under dark surrounds.
Transflective display panels is mainly formed box by color membrane substrates and array base palte, filling liquid crystal between color membrane substrates and array base palte and form liquid crystal cell.Transflective display panels has multiple pixel regions, and described each pixel region comprises multiple subpixel area, and each subpixel area comprises transmission area and echo area.When Transflective display panels is during in reflective mode operation, enter twice of the light of echo area through echo area, and when Transflective display panels is during in transmissive operation pattern, enter the light of transmission area only once through transmission area, like this, just cause the light that under different working modes, in Transflective display panels, different light sources sends different from the light path of transmission area in echo area, make under different working modes the aberration of transmission area and echo area larger, cause the image showing in semi-transmission semi-reflection LCD to occur the inharmonic situation of color.
The reason that the problems referred to above produce be echo area from the light in transmission area because light path is different, and then the phase-delay quantity of the light by transmission area and echo area is not mated.In order to improve the inharmonic phenomenon of color, at present, Transflective display panels adopts dual-box thick spacing design conventionally, it is the thick half of box of the thick liquid crystal cell for corresponding transmission area of box of the liquid crystal cell of echo area, can mate by the phase-delay quantity of the light of transmission area and echo area with guarantee, thereby ensure that the aberration of transmission area and echo area is less and matching in color.But the display panels of this structure is because liquid crystal cell exists the thick difference of box, cause the complex manufacturing technology of display panels, the thick homogeneity of box is wayward, and may produce deformity because the thick difference of liquid crystal cell box makes liquid crystal molecule at the intersection of echo area and transmission area, thereby cause the contrast of intersection not high, color saturation is bad.
