In applying LCD to TV application, one of the most significant factors to be improved is image sticking on the moving picture. Despite the development of technology for fast screen signal processing, it is very difficult to compose a high-quality screen due to the limitation of blinking driving due to the long afterglow time of the backlight. As the Single-LVDS signal system evolves from the Quad Signal Package to respond to 3D, the problem of processing faster signals within a set time is occurring. is becoming In this study, the aim was to realize this operation within 1 frame time by using the blinking backlight, and the existing cold cathode tube lamp was used as the light source. In general, cold cathode tube lamps have a long afterglow time of green, which is responsible for the main emission wavelength, so it is difficult to realize the above characteristics. A backlight capable of flickering within the time frame of the video frame was manufactured, and by using it, it was possible to confirm the effect of resolving the afterimage in a moving image by leaps and bounds.
