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.

Description

technical field [0001] The invention belongs to the technical field of medical displays, in particular to a backlight control system and control method for medical displays. Background technique [0002] The monitor satisfies the needs of people for picture display in their life and work. Depending on the scene used by the display, the requirements for image display are different, and the correction methods used for the displayed image are different. [0003] Medical display is a professional display specially used in the medical field. Compared with other displays, it has its own different characteristics: high brightness, high resolution, high stability, and meets the medical digital image communication standard DICOM (Digital Imaging and Communications in Medicine, Medical Digital Imaging and Communication) Part 14 Grayscale Display Standard Functions, etc. For example: diagnostic monitors are used to display grayscale images, which often require high resolution, high c...
