The invention is suitable for the technical field of display and provides optical units, a color processing method and an LCD display device adopting the method. The color processing method comprises the following steps of: a, reading color parameters from the optical units, establishing a color coordinate triangle of each optical unit according to the read color parameters and determining the overlapping part of the color coordinate triangles to be a reducible color gamut; b, regulating chromaticity coordinate parameters of points outside the reducible color gamut and regulating the points outside the reducible color gamut to the interior of the reducible color gamut; and c, inputting the regulated chromaticity coordinate parameters of the points outside the reducible color gamut into aliquid crystal module of the LCD display device, carrying out display processing according to the regulated chromaticity coordinate parameters by the liquid crystal module and reducing the corresponding colors of the points outside the reducible color gamut. The technical scheme of the invention not only can better realize color reduction, but also can play the role of lowering the compatibility requirements of each LCD optical unit.
Description
technical field [0001] The invention belongs to the field of display technology, and in particular relates to an optical unit, a color processing method and an LCD display device adopting the method. Background technique [0002] The working principle of the liquid crystal display (LCD, Liquid Crystal Display) is completely different from that of the traditional CRT (Cathode Radiation Tube cathode ray tube) display. The liquid crystal display is a layer (or layers) of liquid crystal material sandwiched between two pieces of glass. There are several lamp tubes behind the glass that continuously emit light. The liquid crystal material changes its light transmission state under signal control, so that I saw the image before. The structure of the LCD display includes from bottom to top: a backlight source, which can be a cold cathode tube or a light-emitting diode; The same polarity; there are pixel electrodes and TFT (thin film transistor) circuits on the lower glass substrat...
