Abstract

The invention provides a backlight control system and a backlight control method for a medical display. The backlight control system comprises a sensor module, a peripheral circuit thereof, a main chip, a DDR controller module, a power supply conversion module and an output control module. Whether a user is within the sensing range or not is detected through the sensor module, so that the main chip is controlled to output high level or low level to a liquid crystal display screen of the medical display, energy-saving control for backlight of the medical display is realized, attenuation of the display on brightness and contrast is effectively delayed, and optimal display of medical images is guaranteed at the same time.
