Abstract

The invention discloses a backlight scanning method, a backlight driver and display equipment. According to the embodiment of the invention, at least one scanning signal is generated according to the video signal to drive the backlight source, the number of the scanning pulses in each scanning signal, the number of the masked scanning pulses and the initial position of the masked scanning pulses can be adjusted, so that a backlight extinguishing period is set in a control period, liquid crystal is twisted to change light transmittance, and the brightness of the liquid crystal is improved. The expressive force of a dynamic image is improved, and the effect of motion blur is weakened.

Description

technical field [0001] The invention relates to power electronics technology, in particular to a backlight scanning method, a backlight driver and a display device. Background technique [0002] Motion blur (Motion Blur) refers to the smearing and blurring that occurs when the human eye observes a rapidly changing image displayed on a liquid crystal display (LCD). In order to improve the motion blur of liquid crystal display (LCD), in the prior art, the method of improving the response speed of liquid crystal display can be adopted, and the method of reducing the holding time of liquid crystal display can also be adopted, and at the same time, the holding time of liquid crystal display can be shortened by backlight control . In backlight control, LCDs usually use backlight scanning to improve motion blur. [0003] However, in the existing backlight scanning, the generation method, position and number of scanning pulses in each control cycle are fixed, which has limitations...
