Embodiment Construction

[0034] In the prior art, regardless of whether the display is displaying a dynamic image or a static image, the modules inside the display must operate continuously, which will cause a large amount of power consumption.

[0035] On the contrary, the embodiment of the present invention adds a frame storage unit in the display system. The chipset can be used to determine whether the picture of the video stream is a dynamic picture or a static picture. When the picture of the video stream changes from a dynamic picture to a static picture, the display system can store the still picture in the picture storage unit. Next, if the image of the video stream remains a static image, the display system can operate the video transmission interface in a power saving mode, and the display panel can directly display the image stored in the image storage unit. In this way, when the display system is displaying a static image, the video transmission interface can adaptively operate in the pow...

Abstract

The invention discloses a display system and an electricity saving method thereof. The display system comprises a chip set, a video transmission interface, a display panel and a picture memory unit, wherein the video transmission interface is coupled between the chip set and the display panel. The electricity saving method comprises the following steps that: pictures of a video stream are stored in the picture memory unit adaptively; according to a previous picture and a current picture of the video stream, the chip set judges whether the current picture is a dynamic picture or a static picture; and when the current picture is the static picture, the video transmission interface is operated in an electricity-saving mode and the display panel displays the pictures stored in the picture memory unit. By the electricity saving method, the electricity consumption of the display system can be reduced.

Description

technical field [0001] The invention relates to a power saving technology, and in particular to a power saving technology of a display system. Background technique [0002] At present, the monitors are set with power saving mode and normal mode. When the monitor is not used for a long time, the monitor can be switched into a power saving mode to reduce power consumption of the monitor. When the user wants to use the display again, the display can switch from the power saving mode to the normal mode. [0003] Following the above, in the normal mode, regardless of whether the display displays a dynamic frame or a static frame, all the modules inside the display must operate continuously. That is to say, even if the monitor displays the same static image for a long time, the various modules inside the monitor must continue to operate in order to maintain the above-mentioned static image. Accumulated for a long time, the power consumption of the monitor is quite astonishing. ...
