Embodiment Construction

[0045] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0046] The invention improves the built-in computer or the external camera device with the USB interface, and proposes a new camera device, which can be used to prompt the user to turn off the power supply of the display when shutting down the machine.

[0047] refer to figure 1, is an internal structure diagram of an imaging device according to an embodiment of the present invention. In addition to the image sensor (used to collect image information) that common camera devices have, the camera device also includes: a controller U11, a voice circuit U12, a speaker U13 and a USB interface U14. Wherein, the USB interface U14 is used to realize the data transmission between the camera device and the host computer, and whether it is...

Abstract

The invention provides a method, a device and a system for saving electricity for a display device to solve the problem of unnecessary power consumption because a user forgets to turn off the display device. The system for saving electricity for the display device comprises an electricity-saving device and a monitoring module arranged on a host computer, wherein the electricity-saving device comprises a controller, a voice circuit, a speaker and a transmission interface; the monitoring module is used for detecting a host computer shutdown command and sending the host computer shutdown commandto the controller of electricity-saving device through the transmission interface; the controller of the electricity-saving device is used for receiving the host computer shutdown command through thetransmission interface and sending a start command to the voice circuit; and the voice circuit of the electricity-saving device is used for receiving the start command and outputting voice prompt information of turning off the display device to the speaker for playing. Thus, if the user forgets to turn off the power supply of the display device when shutting down the host computer, the display device can be turned off immediately according to the voice prompt so as to save the power consumption.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a display power saving method, device and system. Background technique [0002] In daily work and life, apart from air conditioners, computers consume the most electricity. According to statistics, an ordinary personal computer consumes about 130 watts to 250 watts of power. In the case of such a large power consumption, many people still have the habit of not turning off the power supply of the monitor after turning off the host computer. Moreover, this phenomenon is very common. According to a survey, more than 80% of users do not turn off the power supply of the display due to forgetting, thus causing unnecessary consumption of power consumption. [0003] For example, if the monitor is not turned off after the main computer is turned off after get off work, the monitor enters a standby state. The standby power consumption of the display is about 5 watts. If the power swi...
