Embodiment 4

[0075] Embodiment 4 is based on the existing logic control board, and directly modifies the overdrive voltage value of the upper and lower limit grayscales of the target grayscale interval according to the overdrive voltage value of X grayscale, so as to achieve the effect of debugging. In the embodiment, it can There is no need to improve the logic control board, but it will reduce the debugging effect of the 0-16 gray scale interval.

[0076] Step S50 , performing brightness grayscale response speed processing of the liquid crystal panel according to the second overdrive comparison table. Such as Figure 8 and Figure 9 As shown, wherein the abscissa is the response time of RGB, and the ordinate is the brightness of the screen display, through overdriving the liquid crystal panel by adopting the overdrive method of the liquid crystal panel in the present invention, the RGB response time in the 0-x order can be obtained to be consistent, and There is no excessive overdrive ...

Abstract

The invention provides an overdrive method of a liquid crystal display panel. The overdrive method comprises the following steps of defining a plurality of grayscale intervals; designating an interpolation method for each interval, and acquiring a first overdrive comparison table of a grayscale by calculation; calling a semitransparent interface on a display interface, acquiring a grayscale valueX of the semitransparent interface, determining the grayscale interval of the X and acquiring an overdrive voltage value of the X grayscale by test; correcting the first overdrive comparison table according to the X grayscale and the overdrive voltage value corresponding to the X grayscale and further obtain a second overdrive comparison table; carrying out processing on the response speed of brightness grayscale of the liquid-crystal panel according to the second overdrive comparison table. The overdrive method provided by the invention has the beneficial effects that the influence on video display when the semitransparent interface is called can be reduced by adding the overdrive voltage value of the grayscale X at the display position of the semitransparent interface when the overdrivecomparison tables are prepared, so that the display effect of the liquid crystal panel is improved.

Description

technical field [0001] The invention relates to a driving method of a liquid crystal panel, in particular to an overdriving method of a liquid crystal display. Background technique [0002] The liquid crystal panel produced by the liquid crystal panel factory is generally an open cell. After being purchased by a display device manufacturer, the liquid crystal panel needs to be designed with a backlight, and then matched with a core board to be used as a finished display device. [0003] When the liquid crystal panel is shipped, it is usually necessary to adjust the liquid crystal panel so that the liquid crystal panel meets the optical specification. Then, after the liquid crystal panel is designed with the core board, the base voltage of the liquid crystal panel is changed by the core board ( Gamma) and chromaticity curve meet their respective debugging requirements. [0004] When watching TV, we will call up menu items from time to time, and the menu items are generally t...
