Abstract

The invention discloses receiving equipment, and a method, a device and a system for controlling the video refreshing rate, wherein the method comprises the following steps that: video stream and the first refreshing frequency of the video stream are received, and the video stream comprises one or more video frames; the video stream is saved to a frame buffer area; and each video frame in the frame buffer area is transferred, and the output time of each video frame is controlled by the second refreshing frequency, wherein the first refreshing frequency is higher than the second refreshing frequency. According to the method, the energy performance on a panel side can be improved, and the power consumption of a whole display system is reduced.

Description

technical field [0001] The invention relates to the field of liquid crystal display screens, in particular to a receiving device, a video refresh frequency control method, device and system. Background technique [0002] The time control chip (TCON) is a subsystem chip in the LCD display. It receives video stream data from the upstream (multimedia processor, or GPU), and reassembles the video stream to drive the source driver IC to display the video stream on the screen. [0003] The eDP interface is a standard display interface belonging to VESA. It is defined for embedded applications, for example it can be used as a video input interface of TCON. The Panel Self Refresh (PSR) function is an optional feature of eDP. The PSR feature enables system-level power savings when displaying images with multiple static display frames. The sink device (sink device) locally stores a static image in the remote frame buffer module (RFB) in the receiver, and displays the image, and at ...
