Abstract

The invention provides a driving circuit and a driving method of a liquid crystal display panel and a display device, which are used for solving the problems that stripes with different brightness exist in the liquid crystal display panel and the display effect is poor. The method comprises the steps that a signal collector collects a backlight control signal and determines a bright state time period and a dark state time period of a backlight source; when the time sequence control chip determines that the backlight source is in the bright state time period, the time sequence control chip reads the first gate control signal from the storage chip storing the first gate control signal corresponding to the bright state time period and outputs the first gate control signal to the gate drive circuit, so the gate drive pixel is charged for a first duration; when it is determined that the backlight source is in the dark state time period, a second gate control signal is read from a storage chip storing the second gate control signal corresponding to the dark state time period, and the second gate control signal is outputted to a gate drive circuit to enable a gate drive pixel to be charged for a second duration, wherein the second duration is less than the first duration.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a driving circuit, a driving method and a display device of a liquid crystal display panel. Background technique [0002] With the rapid development of the field of display panels, people's demand for large-size and high-resolution display panels is increasing day by day, and the display effect requirements of display panel products are getting higher and higher. With the improvement of display panel size and resolution, display panel technology is facing challenges. At present, most TV backlight systems use PWM to control brightness. The backlight switches between high and low levels according to a certain frequency and duty cycle. The brightness of the backlight, due to the high frequency, cannot be recognized by the human eye. However, in the bright state and dark state of the backlight, the presence or absence of light affects the conductor characteristics of the Array Activ...
