Display energy saving device and method

Abstract

The invention relates to a display energy saving device and method. The display energy saving device comprises an average image level calculation module which is configured to calculate an average image level value frame by frame according to inputted display data; a display data sampling and storage module which is configured to sample the inputted display data according to preset sampling pointsand store the sampled data; an image discrimination module which is configured to determine that a display image is a dynamic image or a still image according to the change of the sampled data and the change of the average image level value; an energy saving algorithm module which is configured to adjust the inputted display data according to a preset energy saving algorithm through a display image discrimination result; a display data arrangement and processing module which is configured to arrange and process the display data adjusted by the energy saving algorithm module and output the display data. The present invention also provides a corresponding display energy saving method. The device can effectively avoid the misjudgment of the display screen by the display energy saving algorithm, and avoids the deterioration of the display effect caused by the misjudgment of the energy saving algorithm.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display energy-saving device and method. Background technique [0002] The continuous development and progress of display technologies such as liquid crystal (LCD) displays and active matrix organic light-emitting diodes (AMOLED) displays have brought increasingly rich display products. AMOLED displays have attracted much attention as an emerging technology; people pay more and more attention to environmental protection issues, More stringent energy consumption requirements are put forward for AMOLED displays; in order to reduce energy consumption, the industry regards the economical and energy-saving energy-saving (ECO) mode as an essential function of AMOLED displays. The energy-saving mode can not only save energy consumption, but also alleviate the aging of AMOLED displays problem, prolong monitor life. [0003] see Figure 1A , which is a schematic diagram of the basic f...

Problems solved by technology

[0004] The disadvantage of the existing solution is that when the display picture is a special dynamic picture, but the average image level value does not change or changes very little, it may be judged as a still picture by the energy-saving algorithm, thereby erroneously starting the energy-saving algorithm module and affecting the viewing experience; Adding the traditional method of judging the characteristics of the display screen (still picture and dynamic picture) requires too many hardware logic resources, resulting in a significant increase in cost
