Problems solved by technology

First of all, for the pulsed backlight system shown in FIG. 1A and FIG. 2, the relatively long turn-on / off response time of the cold cathode tube will slow down the response speed of the liquid crystal display panel and reduce the image quality.
Secondly, since the turn-on / turn-off sequence of the light source is predetermined and unchangeable, LCD panels with cold-cathode tubes or plasma light sources controlled by a single main control unit can only provide limited picture quality
In other words, the light source control of the traditional pulsed backlight system cannot effectively and dynamically respond to the display requirements of various images

Abstract

The invention discloses a pulse backlight system for plane display device, containing a backlight region composed of many plane light sources, drivers for plane light source and phase reversers for providing voltage for plane light source according to the video display of plane display device.

Description

technical field [0001] The invention relates to a pulsed backlight system, in particular to a pulsed backlight system related to a flat panel display device. Background technique [0002] Liquid Crystal Display (LCD) technology can be said to be one of the most advanced and popular display technologies used in computer information products (Computer), communication (Communication) and consumer appliances (Consumer Appliance) today. Compared with traditional display technologies such as cathode ray tube (CathodeRay Tube), liquid crystal display technology uses a flat light source and a completely different image display principle, so that the display can have the advantages of flat size and light weight. Generally, liquid crystal display panels have a backlight system to provide a light source to make the displayed data easy to recognize. Traditional backlight systems use cold cathode fluorescent lamps (Cold Cathode Fluorescent Lamp) or plasma lamps (Plasma Lamp) as light sou...
