Embodiment Construction

[0023] Please refer to figure 1 , the display device control system of the present invention is used to automatically control the working state of a display device 10 according to environmental conditions, so as to achieve the purpose of energy saving. A preferred implementation of the display device control system includes several sensors disposed on the display device 10 , a processor 20 and a control circuit 40 .

[0024] In this embodiment, each sensor is an ultrasonic probe 30 . Each ultrasonic probe 30 is used to detect objects within a certain range, and output a sensing signal including the distance between each detected object and the display device 10 . For example, the effective detection range of each ultrasonic probe 30 in this embodiment can be 0.5-6 meters, that is, each ultrasonic probe 30 can obtain the distance between each object and the display device 10 within 0.5-6 meters.

[0025] The control circuit 40 is used for controlling the display device 10 to ...

Abstract

A display equipment control method is used for controlling operating states of a display device. The method includes the steps of acquiring sensing signals, including the distances between objects and the display device, output by sensors; judging whether the distance between one object and the display device changes nor not; when the time of change of the distance between the object and the display device reaches a first preset time, controlling the display device to stop operating. The method allows the display device to be automatically shut down when a user leaves the display device, so that energy saving is achieved. The invention further provides a display equipment control system.

Description

technical field [0001] The invention relates to a display device control system and method, in particular to an energy-saving display device control system and method. Background technique [0002] Present display devices, such as liquid crystal televisions, have been widely used. Sometimes, the user returns to watch a TV program after leaving for a period of time (such as half an hour), and the user usually does not turn off the display device during this time period. At this time, the circuits in the display device are still in working state, which leads to considerable waste of electric energy. Contents of the invention [0003] In view of the above, it is necessary to provide a display device control system and method for automatically switching on and off according to environmental conditions. [0004] A display device control system, used to control the working state of a display device, the display device control system includes: [0005] A plurality of sensors a...
