Problems solved by technology
As a touch screen device, since the device cannot predict when a touch event will occur, the actual device works in a non-touch state most of the time. However, the touch screen system needs to continue to maintain a high power consumption state to respond to events that occur at any time. Touch events, such a high power consumption working state shortens the use time of the device, and also reduces the service life of the device

The invention relates to the technical field of a touch display screen, in particular to a low power-consumption device for an optical touch screen, which comprises an optical touch screen, wherein optical sensors are arranged on four corners of the optical touch screen, light emitting strips are arranged on four sides of the optical touch screen, the optical sensors and the light emitting strips are formed into a touch system, and proximity sensors are arranged on the four sides of the optical touch screen and used for feeding back to the system after sensing that bodies or other objects approach the optical touch screen. Compared with the prior art, the touch system can be kept in a low power-consumption state by the low power-consumption device, so that attenuation aging of an optical element is reduced, the service life of equipment can be prolonged, power consumption of the system is reduced, and the service time of the equipment can be increased.
Description
technical field [0001] The invention relates to the technical field of touch screens, in particular to a low power consumption device for optical touch screens. Background technique [0002] The operation of traditional display terminal human-computer interaction system needs to use the mouse, keyboard or the button of the device to do input, selection and other operations. The device often needs to be plugged in or have the above input devices, which brings inconvenience to the installation, use and maintenance of the device. [0003] However, with the rise of touch panel (Touch panel) technology, the appearance of the human-computer interaction system has become simpler, and the operation is easier to use. Personnel can interact with the device through touch. The data information can be directly displayed on the display area. Perform actions such as zooming out, zooming in, and dragging, and can directly operate the screen menu to operate virtual buttons, and can operate t...
