Abstract

For local backlight dimming technology, we revealed relationships between light profile of segments and picture degradations by performing a simulation. Based on the result, we optimized the light profile and developed a WDRLCD prototype. This prototype can enhance contrast of an LCD to over 4,800x while minimizing the picture degradations.
