BACKLIGHT CONTROL APPARATUS OF LIQUID CRYSTAL PANEL, LIQUID CRYSTAL TV SET AND MCU CHIP

摘要

A backlight control apparatus of a liquid crystal panel, a liquid crystal TV set and an MCU chip are disclosed, and the apparatus includes: an FRC chip, an MCU chip connected with the FRC chip, and a backlight drive chip connected with the MCU chip; and calculates brightness data of N image zones of a current image frame, converts the brightness data of the N image zones into backlight values of N backlight zones and sends the backlight values to the Micro Controller Unit (MCU) chip; and divides the N backlight zones into M backlight areas, searches a preset gain curve for a gain corresponding to each backlight area according to the average of the backlight values of the backlight zones included in the each backlight area, and adjusts the backlight values of the N backlight zones by M gains searched for.
