Embodiment Construction

[0027] figure 1 It is a light source component used in the color adjustment method of the color sequential liquid crystal display according to an embodiment of the present invention. see figure 1 The color adjustment method of this embodiment can be applied to a color-sequential liquid crystal display, which has at least one light source assembly 100, and the light source assembly 100 can be installed in the backlight module of the color-sequential liquid crystal display.

[0028] Based on the above, the light source assembly 100 includes at least one white light source 102, a plurality of monochromatic light sources 104, 106, 108 and a circuit board 110, and the white light source 102 and these monochromatic light sources 104, 106, 108 are assembled on the circuit board 110, Wherein the white light source 102 and the monochrome light sources 104, 106, 108 can all be light emitting diodes.

[0029] In detail, the white light source 102 can be a white light emitting diode, an...

Abstract

The invention provides a color regulation method of a color sequence type liquid crystal display, which is applied to the color sequence type liquid crystal display comprising at least one white light source. The color regulation method comprises the following steps: firstly, converting an original image signal into a bit of target color point in a color degree map in a color space; then, calculating a modified image signal with a white datum according to the original image signal; next, using a matrix group for converting the modified image signal into a bit of main color point in the color degree map; and then, calculating a plurality of sub map field data according to the main color point and the target color point. The main color point falls on the target color point through the sub map field data.

Description

technical field [0001] The invention relates to an image adjustment method of a display, and in particular to a color adjustment method of a color sequential liquid crystal display. Background technique [0002] It is known that a color sequential liquid crystal display (color sequential LCD) often suffers from color breakup when displaying images, resulting in reduced image quality. Specifically, when the known color sequential liquid crystal display displays a moving image of a moving object, the viewer's eyes will unconsciously stare at the object and track the movement of the object. [0003] At this time, the three primary color fields (fields) that constitute the image of the object, that is, the red field (red field), green field (green field) and blue field (blue field), will not be projected on the same position on the retina , so that the viewer will perceive the edges of the moving object as a rainbow-like separation of colors. [0004] In order to improve the c...
