Abstract

The invention provides a driving circuit and a driving method of a display panel and a display device. The display panel comprises a first half screen and a second half screen, the driving circuit comprises a main time sequence control module, an auxiliary time sequence control module, a system-level chip and a delay compensation module, and the delay compensation module determines a voltage compensation value Vbc according to feedback signals of the main time sequence control module and the auxiliary time sequence control module. According to the voltage compensation value Vbc, the system-level chip enables the voltage value of the data signal output to the second half screen by the auxiliary time sequence control module to be increased by Vbc, so that the voltage values of the pixel units in the second half screen and the pixel units in the first half screen are consistent after the pixel units are charged by the same frame of data signal. According to the driving circuit provided by the invention, the pixel unit in the second half screen can be charged to the target voltage value by detecting the delay time value and increasing the voltage value of the data signal output by the auxiliary time sequence control module, so that the problem that the display of the left and right half screens of the display panel is not uniform is solved.

Description

technical field [0001] The present application relates to the field of display panels, and in particular, to a drive circuit, a drive method and a display device of a display panel. Background technique [0002] With the development of display technology, customers have higher and higher requirements for refresh rate, resulting in many high refresh rate display devices, common ones are 165HZ, 240HZ, 360HZ and so on. The use of high refresh rate monitors can greatly improve the user experience and visual enjoyment, and can meet the needs of more professionals, but it also brings many problems, such as insufficient charging time, serious mischarge, and poor panel uniformity. [0003] In the existing high refresh rate display device, due to the large amount of data transmitted, a main Tcon (Timing Controller, timing controller) and a sub Tcon are usually used to control the left and right half screens respectively. Among them, the main Tcon plays the main control role. In addi...
