Abstract
A TV set including a liquid crystal panel, a processor-readable storage medium storing instruction units for providing the TV set functions to control backlight of the liquid crystal panel; and one or more processors in communication with the storage medium to execute the instruction units, wherein the instruction units include: an image information amount determining unit (102); the backlight gain retrieving unit (104); a backlight value extracting unit (106); the backlight value processing unit (108); and a backlight value transmitting unit (110). Correspondingly a method of controlling backlight of a liquid crystal panel is further disclosed. In the technical solution of the disclosure, a backlight modulation coefficient can be modulated dynamically according to the amount of image information to perform backlight enhancement on an image with a large amount of information.
