PROBLEM TO BE SOLVED: To provide a controller for dynamically adjusting the back light luminance and color system of a liquid crystal display by external field luminous intensity. SOLUTION: The above controller is provided with a display dynamic controller, an environmental luminance sensor and a color system array board which are coupled to a back light of the liquid crystal display. The display dynamic controller generates a back light luminance control signal by the magnitude of the environmental luminance signal detected by the environmental luminance sensor and sends the signal to the back light of the liquid crystal display, thereby changing the environmental luminance of the liquid crystal display. A microcontroller generates a plurality of different color system control signals and sends the signals to the color system array board, thereby controlling the color system manifested by the liquid crystal display.
