However, this watch can only be overdriven for the change of the middle gray scale, but the driving voltage from other gray scales to the highest gray scale (255 gray scale in this picture) is already the maximum value, and no higher voltage can be given. Therefore, it is impossible to reduce the response time by modifying the data table of the overvoltage driving signal. Therefore, it is extremely necessary to have a method to make the highest gray level also have an overdrive effect to improve the change of the pixel from the gray level of the previous frame to the gray level. The response time of the highest gray level of the current picture

Embodiment Construction
[0016] Please refer to figure 2 , figure 2 Shown is a schematic diagram of an embodiment of the driving device of the display of the present invention. In this embodiment, the display includes a display panel 140 (such as a liquid crystal display) and a driving device 100 , and the driving device 100 is used to drive the display panel 140 to display image images. As shown in the figure, the driving device 100 includes an overvoltage driving module 120, a reference voltage generating module (such as a gamma reference voltage generating module 130) and a control module 150 (such as a color tracking module). The related elements of the technical content of the invention are shown in figure 2 However, the present invention does not limit the driving device 100 to only include figure 2 components shown. In addition, in this embodiment, the display panel 140 is a liquid crystal display, however, this is only an example and not a limitation of the present invention, that is, ...

The invention provides a method and a device for driving a display. The driving method comprises the following steps: setting a plurality of driving voltage values which correspond to a plurality of gray scales respectively, wherein the plurality of gray scales comprise a first gray scale and a second gray scale less than the first gray scale, and a first driving voltage value corresponding to the first gray scale is less than a second driving voltage value corresponding to the second gray scale; and controlling the display to only display the second gray scale. In such a way, the driving method in the invention can reduce the reaction time of the display (a liquid crystal display, for example).
Description
technical field [0001] The invention relates to a display driving method and device, in particular to a driving method and a driving device capable of reducing the response time of the display. Background technique [0002] The principle of liquid crystal display (liquid crystal display, LCD) image display is to change the arrangement of liquid crystal molecules in each pixel (pixel) by applying an external driving voltage, thereby changing the polarization state of light and the transmission rate of light, thus presenting different images. brightness. However, the response of liquid crystal molecules to the external driving voltage is very slow, so compared with the traditional cathode ray tube (cathode ray tube) display, the liquid crystal display will have image blur when displaying animation images. [0003] To solve this problem, an overdrive method is generally used. For example, if it is desired to obtain a brightness of a gray scale G1, an external driving voltage ...
