Luminance compensation method of dynamically driven scene sequence color liquid crystal display

Abstract

The invention relates to a luminance compensation method of a dynamically driven scene sequence color liquid crystal display. In the dynamically driven scene sequence color liquid crystal display by a line-by-line scanning method, the scanning method of the dynamically driven scene sequence color liquid crystal display has an inverse sequence of line scanning in the two adjacent frame periods or carries out line scanning twice in a scanning interval of the same color in the same frame period with the inverse sequence. The invention can achieve the effect of basic conformity of display luminance and chrominance of the dynamically driven scene sequence color display.

Description

technical field [0001] The invention relates to a brightness compensation method for dynamically driving a field-sequential color liquid crystal display, in particular, a dynamically driving field-sequential color liquid crystal display includes a liquid crystal display, a backlight source, a backlight driver and a liquid crystal display driver. On the bottom side of the display screen, the backlight driver and the liquid crystal display driver respectively drive the backlight source and the liquid crystal display to dynamically drive the brightness compensation method of the field sequential color liquid crystal display. Background technique [0002] Field-sequential color liquid crystal display usually divides a color picture (frame) into three pictures (fields) of red (R), green (G) and blue (B) sequentially in time, and then switches those pictures sequentially at high speed (fields) constitute a color picture (frame). If the three primary colors of R, G, and B are used...

Problems solved by technology

If this dynamic drive field sequential color liquid crystal display is displayed in a progressive scanning mode, such as figure 1 As shown, the liquid crystal display is progressively scanned from the first line to the Nth line of the line scan (as shown by the arrow), and its display brightness is as follows: figure 2 As shown, the lighting time of the first row is the longest, and the lighting time of the Nth row is the shortest. Therefore, its brightness changes gradually from bright to dark from the first row to the Nth row. This change in display brightness will directly Affects the chromaticity change of the dynamically driven field sequential color liquid crystal display, forming chromatic aberration
