Problems solved by technology

For example, when determining the overdrive value of an M-grayscale image switched to N-grayscale, it is necessary to exhaustively verify from M-grayscale to 0, 1, 2, 3, 4...255 to find the closest brightness to N-grayscale The gray scale is used as the value in the overdrive lookup table. It takes 256*256 times to adjust a value before a value in the overdrive lookup table can be completely debugged. The debugging efficiency is low.

Embodiment Construction

[0039] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] The main solution of the embodiment of the present invention is: control the adjustment function of the source drive signal in the display panel to turn off; control the display panel to display the first frame image and the second frame image in sequence, the gray scale of the first frame image is the initial gray The gray scale of the second frame image is the target gray scale; collect the characteristic value of the light change caused by the gray scale change in the process of switching from the first frame image to the second frame image; according to the light change The eigenvalues ​​determine the overdrive value.

[0041] Because the values ​​in the overdrive lookup table need to be debugged many times by methods such as exhaustive tests, the debugging efficiency of the overdrive lookup table is low. ...

Abstract

The invention discloses a driving method, comprising the following steps: controlling the closing of the adjustment function of the source driving signal in the display panel; is the initial gray scale, the gray scale of the second frame image is the target gray scale; collecting the characteristic value of the light change caused by the gray scale change during the process of switching the first frame image to the second frame image; and, An overdrive value is determined according to the light change characteristic value. The invention also discloses a driving device, a driving device, a display and a readable storage medium. The invention can improve the debugging efficiency of the display overdrive lookup table.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a driving method, a driving device, a driving device, a display and a readable storage medium. Background technique [0002] Currently, in a display panel, especially a liquid crystal display panel, an overdrive technology is used to improve the response speed of the display image displayed on the display. At present, when debugging the overdrive lookup table, most of them use exhaustive experiments to find suitable values ​​as the data in the overdrive lookup table. For example, when determining the overdrive value of an M-grayscale image switched to N-grayscale, it is necessary to exhaustively verify from M-grayscale to 0, 1, 2, 3, 4...255 to find the closest brightness to N-grayscale The gray scale is used as the value in the overdrive lookup table. It takes 256*256 times to adjust a value before a value in the overdrive lookup table can be completely debugged, and t...
