Infrared control device

Abstract

The invention relates to an infrared control device which comprises a plurality of infrared transmitting tubes, a plurality of infrared receiving tubes, an infrared luminescence control circuit, an infrared receiving control circuit, a processor and a display panel, wherein the infrared transmitting tubes and the infrared receiving tubes are arranged in a staggered mode below the display panel and towards the same direction, the infrared transmitting tubes are controlled by the processor through the infrared luminescence control circuit to transmit infrared signals, the infrared receiving tubes are controlled by the infrared receiving control circuit to receive the reflected infrared signals transmitted by the infrared transmitting tubes, and state sampling signals are transmitted into the processor after the states of the infrared receiving tubes are sampled. The processor comprises an infrared processing unit, a control unit and a display processing unit, wherein the position of a control point is determined by the infrared processing unit according to the state sampling signals of the infrared receiving tubes, a corresponding control signal is output by the control unit according to the position of the control point, a corresponding function is started, and the display panel is controlled by the display processing unit to display a corresponding interface.

Description

technical field [0001] The invention relates to an infrared control device, in particular to a non-contact infrared control device. Background technique [0002] Infrared technology has been widely used in the field of touch applications. For example, an infrared touch screen is to install several pairs of infrared emitting tubes and infrared receiving tubes in a certain order around the edge of a display screen. The infrared rays form a grid structure on the surface of the display screen. When there is a touch, fingers or other objects will block the infrared rays passing through the point, and the control system will judge the position of the touch point on the display screen. However, the traditional infrared touch screen requires the infrared emitting tube and the infrared receiving tube to be arranged on the edge of the display screen oppositely, and requires the electronic device to reserve a certain space to transmit infrared light, which makes it difficult for the el...

AI Technical Summary

Problems solved by technology

However, the traditional infrared touch screen requires that the infrared emitting tube and the infrared receiving tube be arranged opposite to the edge of the display screen, and requires the electronic device to reserve a certain space for transmitting infrared light, which makes it difficult for the electronic device using the infrared touch screen to meet the requirements of thinning, small Dimensional Design Requirements

In addition, the user directly touches the screen to operate, the screen is easily polluted by dirt, and its service life is also affected to a certain extent
