Abstract

The present invention provides a driving circuit, a driving method and a display device of a liquid crystal display panel, which are used to solve the problems of uneven light and dark stripes and poor display effect in the liquid crystal display panel. This application: the signal collector collects the backlight control signal, and determines the bright state time period and the dark state time period of the backlight source; when the timing control chip determines that it is in the bright state time period, it controls the The first gate control signal is read in the storage chip of the signal, and is output to the gate drive circuit, so that the gate drive pixels are charged for the first duration; Read the second gate control signal from the storage chip corresponding to the second gate control signal of the segment, and output it to the gate drive circuit, so that the gate drive pixels are charged for the second duration; the second duration is shorter 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...
