Abstract

The invention provides a time sequence controller, a driving control method and a gate driving circuit and method. The time sequence controller comprises a controller body, a data receiver, a comparer, an arithmetic unit and a signal generator; the arithmetic unit is used for calculating the sum of maximum data voltage corresponding to pixels in all rows for each frame of pixel data under the control of the controller body and determining the opening time corresponding to the pixels in each row according to the maximum data voltage corresponding to the pixels in each row and the sum of the maximum data voltage corresponding to the pixels in all the rows; the signal generator is used for generating a corresponding control signal according to the opening time corresponding to the pixels in each row for each frame of pixel data under the control of the controller body, so that a scanning signal generating unit generates a corresponding gate scanning signal according to the control signal. The time sequence controller can increase the charging rate of the pixels, and solve the problem of picture distortion caused by the insufficient charging rate.

Description

technical field

[0001] The present invention relates to the field of display technology, in particular to a timing controller, a driving control method, a gate driving circuit and a method. Background technique

[0002] The resolution of a liquid crystal display mainly depends on the number of pixels it contains. In the case of a fixed frame time, as the resolution of the liquid crystal display becomes higher and higher, the charging time of each pixel in a frame becomes shorter and shorter. This is likely to cause insufficient charging of some pixels, so that the luminous brightness of the corresponding pixels is insufficient, resulting in picture distortion. Contents of the invention

[0003] An object of the present invention is to increase the charging rate of pixels and improve the image distortion problem caused by insufficient charging rate of pixels.

[0004] In a first aspect, the present invention provides a timing controller, comprising:

[0005] controller, ...
