Embodiment Construction

[0028] In the traditional over-driving (Over-Driving, OD) comparison table, the over-driving index look-up table for the gray scale change between two pictures is usually set with a single pixel as the smallest unit. However, a single pixel usually includes more than three sub-pixels corresponding to different colors, such as red (R), green (G), blue (B) and other three colors. Only a single overshoot lookup table is used to perform overshoot compensation and apply it consistently to the sub-pixels of the three colors, and the changing speed of different colors is often inconsistent, which is the so-called dragging phenomenon. Therefore, the present invention proposes an overdrive adjustment method, which establishes different overdrive lookup tables (OD tables) corresponding to multiple subpixels of different colors in a single pixel, such as three-color overdrive lookups corresponding to red, green, and blue. Table (RGB-OD tables).

Abstract

Provided is an over-excitation drive adjusting method and a system. The over-excitation drive adjusting method comprises the steps of setting a color temperature value of at least one pixel which includes a plurality of sub-pixels with different colors; measuring over-excitation indexes of the sub-pixels; and adjusting the over-excitation indexes of the sub-pixels to be the same target level.

Description

technical field [0001] The present invention relates to a display driving adjustment method, and in particular to an over-driving adjustment method and system thereof in display applications. Background technique [0002] Traditionally, when liquid crystal display devices display dynamic pictures, image sticking is often prone to occur. The reason is that the liquid crystal needs a certain reaction time in the process of rotating and switching. Afterimage. In order to solve such a situation, over-driving (Over-Driving, OD) display technology is generally used to solve it. By applying a driving signal that is deliberately enlarged (including the amplification of the rising range and the amplification of the falling range), the liquid crystal between adjacent frames The switching speed is increased, so that the display signal can quickly reach the ideal signal potential within the screen switching time, reducing the occurrence of afterimages. [0003] The generally known ove...
