Abstract

The invention relates to a display device capable of automatic brightness adjustment. The display device comprises a control module, a number of backlight modules, a display screen and a number of brightness detection modules; the display screen has a plurality of display zones, and each display zone corresponds to a backlight module; the control module comprises a signal detection module, a light adjustment module, a PWM driving module and a controller; the signal detection module is connected with all the brightness detection modules, the signal detection module is connected with the controller, the controller is connected with the light adjustment module, and the light adjustment module is connected with the backlight modules via the PWM driving modules. After brightness of the display zones is detected via the brightness detection modules, brightness signals are generated, the brightness detection modules are used for sending to the brightness signals to the controller, the controller controls the light adjustment module to generate corresponding light adjustment parameters corresponding to the brightness signals, the backlight modules are driven to work via the PWM driving module, luminance of all backlight modules is matched with brightness of the display zones, brightness can be automatically adjusted according to current luminance, and convenience of brightness adjustment can be realized.

Description

technical field [0001] The invention relates to the technical field of LED display, in particular to a display device with automatic brightness adjustment. 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 display device with auto...
