LIQUID CRYSTAL DISPLAY DEVICE

摘要

PURPOSE: A liquid crystal display device is provided to reduce the optical interference by performing 2D scanning in horizontal direction and vertical direction. CONSTITUTION: Light source units are placed on the lower part of a liquid crystal panel in block unit. A light source driving unit drives the light sources to horizontal direction and vertical direction. The light source driving unit shifts the switch on/off phase of light sources which are placed in the horizontal direction and the vertical direction. The light source driving unit varies the on and off time of the light sources by the data signal which is transmitted to the liquid crystal panel.
