Abstract
The unceasing flat light source is used in the conventional Liquid Crystal Display (LCD) as the backlight, the dynamic contrast ratio of LCD is limited due to light leakage. The implementation of High Dynamic Range (HDR) LCD is introduced based on LED backlight with area control technology, which can not only acquire high contrast ratio and large color gamut but also save power efficiently. According to practical algorithm flow, there are three important aspects described individually: driving value of LED, distribution of backlight and compensation of LCD panel. The development of display device is summarized based on LED backlight.
