Problems solved by technology

In the case of displaying a static picture, the data of each frame is the same, and the data called by the image processor is also exactly the same. This kind of call is meaningless, but consumes a lot of power consumption, resulting in unnecessary power consumption loss
The higher the refresh rate, the more serious this unnecessary power loss

Abstract

The embodiment of the invention discloses a display device and a control method thereof. The display device of the embodiment of the present invention includes a first processor for processing video frame content, a monitoring device for monitoring video frame content updates and controlling a second processor group, and a second processor group including a plurality of different second processors. Controlling the second processor group to a refresh operation state if a change in the content of the video frame is detected; if it is detected the the content of the video frame has not changed, the second processor group is controlled not to refresh the operating state. The embodiment of the invention controls the second processor group to be different working states by monitoring whether thevideo frame content is changed, thereby effectively reducing the calling times of the second processor and achieving the purpose of reducing the display power consumption.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display device and a control method thereof. Background technique [0002] In the current display driver chip, each image processor inside the display driver will adjust the image quality, brightness, etc. one by one due to the need for dynamic adjustment of display image quality, brightness, power supply, etc. For example, brightness is controlled by a brightness control module (Brightness control module, BC), and power is managed by a dynamic power management module (Dynamic Power Management Module, DPM). [0003] The display driver is divided into two parts: image writing and image display. In most of the picture display applications, there is a process of displaying static pictures, and the Application Processor (Application Processor) ， AP) The frequency of updating video frame content in the storage device is low (that is, the frequency of image writing is low). Howev...
