Energy-saving method for displayer

Abstract

The invention relates to an energy-saving method for a displayer. The method comprises the following steps of pre-generating a training sample; acquiring information of an image in front of the displayer in real time through image acquisition equipment; scanning the image; judging whether a human face exists or not by human face detection technology, if the human face does not exist, generating a user free signal, and outputting the signal to perform energy conservation on the displayer; and if the human face exists, further by human eye detection technology, intercepting an area where the human eyes are, extracting characteristics to generate a test sample, comparing the test sample with the training sample so as to generate a control signal of a user busy signal or a user free signal, and outputting the control signal to control the working way of the displayer. Therefore, the problem of energy source waste caused when the displayer is idle is solved, and the defects of high error rate and poor experience feeling of the current method are overcome.

Description

technical field [0001] The invention relates to an energy-saving method, in particular to an energy-saving method applied to a display. Background technique [0002] With the advancement of science and technology, information technology is widely used in various fields of economy and society. At the same time, the earth's resources are constantly being consumed and lead to many environmental problems, such as global warming caused by a large amount of carbon dioxide emissions. In daily life and work, people often do not turn off computer monitors or TV sets, which wastes resources and causes unnecessary consumption of resources. [0003] Take a computer monitor as an example. A 17-inch LCD monitor has a power of 30w. Assuming that the monitor is idle for 2 hours a day, it will consume 0.03 kilowatt-hours of electricity in vain. Then one computer will waste 0.03×2×0.7×365=15.33 yuan per year; if calculated with 100 computers, it will waste 1533 yuan a year. For 100 32-inch ...

Problems solved by technology

[0004] In order to save unnecessary waste of resources, the industry uses new luminescent materials to improve the production materials of displays. However, the cost of this new luminescent material is very high, which increases the production cost of displays; or use For example, the infrared induction method is used to detect the distance between the person and the display to realize the automatic switch, but the biggest disadvantage of the method is that it is easily affected by obstacles, so that the display is turned off by mistake, which brings inconvenience to the user and reduces the user's safety. sense of experience
