| dc.description.abstract | A high dynamic range liquid crystal display (HDR-LCD) can enhance the contrast ratio of images by utilizing locally controlled dynamic backlight. We studied the HDR-LCD as a dual-panel display: a backlight module and a liquid crystal (LC) cell. As the gamma of the LC signal, the backlight module was also endowed with a gamma function to control the contrast ratio of HDR images. The inverse of a mapping function (IMF) method proposed as a dynamic gamma mapping curve for the backlight module, has been demonstrated to further improve in HDR image quality. By implementing the IMF method on a 37 '' HDR-LCD TV with 8 x 8 backlight zones, the image contrast ratio can reach similar to 20000:1 while maintaining high brightness, clear image detail, and an average power reduction of 30%. | en_US |
