Description

technical field

[0001] The invention relates to a driving method of a liquid crystal display backlight module, in particular to a driving method of a liquid crystal display backlight module capable of improving motion blur. technical background

[0002] Liquid Crystal Display (LCD) has the characteristics of light and thin appearance, low power consumption, and no radiation pollution. It has been widely used in information products such as computer systems, mobile phones, and personal digital assistants (PDA). . The liquid crystal display uses the rotation of the liquid crystal to control the penetration of light to display gray scales of different brightness. Compared with the cathode ray tube (CRT) display using an impulse-type display method, the liquid crystal display uses a voltage continuous holding (hold-type) driving method. Since the rotation of the liquid crystal changes continuously, the reaction speed of animation performance is slower than that of the cathode ...
