Abstract

The invention relates to a dimming display device, which comprises a control module, a plurality of backlight modules, a display screen and a plurality of temperature detection modules, wherein the display screen includes a plurality of display areas; each display area corresponds to one of the backlight modules and each display area is provided with at least one of the temperature detection modules; the control module comprises a signal detection module, a dimming module, a PWM driving module and a controller; the signal detection module is connected to the various temperature detection modules; the signal detection module is connected to the controller; the controller is connected to the dimming module; and the dimming module is connected to the plurality of backlight modules by virtue of the PWM driving module. In accordance with temperture detected by the temperature detection modules, dimming parameters are generated, and subsequently, the PWM driving module is controlled to drive the backlight modules to work in accordance with the dimming parameters, so that the brightness of the display screen is regulated more conveniently; and in addition, since light emitting of the backlight modules is matched with temperatures of the corresponding display areas, the circumstance that the display screen is locally excessively high in temperature is effectively avoided, so that energy consumption is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of LED display, in particular to a dimming display. Background technique [0002] With the continuous development of LED liquid crystal display, LED display has been able to achieve split screen display, and can be used to control the brightness of each split screen separately. The brightness control of the split screen is driven by the backlight driver module to control the backlight. The module is realized by controlling the work of the backlight driver module. The traditional backlight driving method requires the user to manually select or manually control the backlight mode, and the number of split screens that can be controlled by brightness adjustment is small, which causes inconvenience for users. Difficulty then rises, further exacerbating user inconvenience. Contents of the invention [0003] Based on this, it is necessary to provide a dimming display for the disadvantage of inconvenient use of ...
