Problems solved by technology

However, in these two ways, the former must be directly touched by the power button by the user, but after the projector is installed in a form such as a ceiling, it is almost impossible for the user to directly touch the power button, so by directly operating the power button It is very inconvenient to realize the control of turning on and off the main power supply of the projector
Although the latter does not require the user to directly touch the pow

Embodiment Construction

[0063] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0064] The display device with VGA interface mainly receives the signal from the computer for display through the VGA interface. Usually, the main power supply of the display device is mostly for receiving the signal from the VGA interface. Before receiving the signal from the VGA interface, turn on the Display device mains power basically serves no other purpose. Therefore, the connection of the main power supply can be controlled directly by detecting whether a valid signal is input to the VGA interface. Therefore, the main idea of ​​the present invention is to detect whether an effective signal has been input to the VGA interface, and if it is detected that the VGA interface has input an effective signal, then the main power supply of the display device is turn...

Abstract

The disclosed control device for main power of display comprises: an access control module (103), a signal processing module (301), and an electrifying control module (102) to detect signal from (301) and verify the VGA interface (302) to drive the module (103) electrifying the power. This invention improves display intelligent degree.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a display device main power control device and a display device main power control method. Background technique [0002] With the development of multimedia technology, display devices not only occupy a place in business applications, but also are used more and more in the education industry. With the improvement of display device performance and price reduction, home applications are becoming more and more extensive. Among them, the projector is particularly obvious. [0003] Taking a projector as an example, the display device is usually turned on and off by buttons or a remote controller. The former sets the power button of the projector on the shell of the projector itself, and the user manually presses the power button to turn on and off the projector; the latter uses the remote control attached to the projector to use infrared or other wireless transmission ...
