Abstract

The invention provides a pixel charging duration adjustment method, a time schedule controller and a display device, and the adjustment method comprises the steps: using a part of the duration of a field blanking region of each frame of image to compensate for the duration of a row blanking area of each row of pixels under the condition that the charging duration of each frame of image is kept unchanged; gradually increasing the duration of the row blanking areas of the pixels from the first row to the nth row from the near to the distant from a source driver, so that the duration of the row blanking areas of the pixels from the first row to the nth row is gradually increased, namely, the charging duration of the pixels from the first row to the nth row from the far to the near from the source driver is gradually increased. Therefore, the defect that the resistance-capacitance loads of the data lines corresponding to the pixels from the first row to the nth row from near to far away from the source driver are larger and larger is correspondingly compensated, so that the charging duration of each row of pixels is increased, namely the charging rate of each row of pixels can meet the requirement, and the problem that the charging rate of the pixels in the far-end row is insufficient is solved.

Description

technical field [0001] The present application relates to the field of display technology, and in particular to a method for adjusting pixel charging duration, a timing controller and a display device. Background technique [0002] When the gate driver provides the scanning signal to turn on the pixels in the display panel, the source driver supplies data signals to the pixels in the display panel through the vertical data line for charging, but because the data line has a resistance-capacitance load, and the distance from the source driver is greater The larger the resistance-capacitance load of the distant data lines, the shorter the charging time of the pixels farther away from the source driver, so the charging rate of the pixels farther away from the source driver may be insufficient. The phenomenon of insufficient charging rate of row pixels becomes more and more obvious as the refresh rate of the display panel increases and the resolution increases due to the increase...
