Method for improving chromatic aberration of liquid crystal display (LCD)

Abstract

The invention relates to a method for improving the chromatic aberration of a liquid crystal display (LCD). The method is characterized in that adjacent protrusions or slits in each sub-pixel are not equal. In the invention, the heeling conditions of liquid crystal molecules under driving voltage are increased through improving the protrusions on a CF substrate of a VA mode LCD to realize more domain displays, which is beneficial to the improvement of the chromatic aberration without influencing other optical characteristics and increasing manufacture procedures. Compared with other domain realization modes, the invention does not increase the pay expenses in the aspect of driving.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a method for eliminating color difference of a liquid crystal display, in particular to a method for improving the color difference of a liquid crystal display by changing the size of a raised structure or a groove in a sub-pixel to realize display without color cast. Background technique [0002] For VA (Vertical Alignment) mode LCDs (Liquid Crystal Displays), the liquid crystals used are negative liquid crystals. The orientation of liquid crystal molecules is deflected after voltage is applied. LCDs in VA (vertical alignment) mode generally use protrusion (protrusion structure) or ITO slit (grooves on pixel electrodes) on CF (color filter) substrates and TFT substrates. ) structure. The role of the VA type PI (polyimide alignment film) film makes the liquid crystal molecules align in a direction close to the direction perpendicular to the panel surface without applying voltage.

Problems solved by technology

[0004] The purpose of the present invention is to invent a method for improving the chromatic aberration of a liquid crystal display in view of the problem that in the existing VA mode LCD, the raised structure or the groove structure in the sub-pixels are of the same size, which may easily cause chromatic aberration under different viewing angles.
