Abstract: It is possible to provide a light source unit for a display device or a display device not causing interference fringe or waving noise caused by interference between a vertical synchronization signal used for driving a display panel and a flash cycle of the light source. A light source unit for a display device for operating a light source according to a signal in which ON time for turning ON the light source periodically appears includes means for generating a random number and light adjusting means. The light adjusting means thins the ON time from the signal at random according to the brightness adjustment level by the user so that the blanking time when the light source is OFF appears irregularly.

TL;DR: In this paper, the authors proposed to reduce the irregularity of display caused by the distortion of a signal electrode waveform and to improve display quality by deciding the width of the on-pulse of a driving waveform impressed on the signal electrode from the right end of a selection period in a 1st frame and deciding it from the left end thereof in a 2nd frame.
