TV Set, Method Of Controlling Backlight Of Liquid Crystal Panel And Storage Medium

A TV set, comprising:

• 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 comprise:
• an image information amount determining unit configured to determine an amount of image information of a video signal inputted and to transmit the amount of image information to a backlight gain retrieving unit;
• the backlight gain retrieving unit, in communication with the image information amount determining unit, configured to retrieve a backlight gain coefficient according to the amount of image information;
• a backlight value extracting unit configured to extract a backlight value of the video signal and to transmit the backlight value to a backlight value processing unit;
• the backlight value processing unit, in communication with the backlight value extracting unit and the backlight gain retrieving unit, configured to calculate a gained backlight value from the backlight gain coefficient and the backlight value;
• and
• a backlight value transmitting unit, in communication with the backlight value processing unit, configured to transmit the gained backlight value to a light source drive circuit of the liquid crystal panel.
