Abstract

The invention discloses an infrared touch screen and a coverage detection method and system thereof, and the method comprises the steps: a signal intensity detection step: detecting the intensity of asignal received by an infrared receiving tube in each infrared geminate transistor; a shielding judgment step: judging whether the corresponding infrared geminate transistors are shielded or not according to the signal strength detected by the signal strength detection units; if the signal intensity detected by the infrared receiving tube is smaller than a set first threshold value, judging thatthe corresponding infrared geminate transistor is not shielded; and if the signal intensity detected by the infrared receiving tube is greater than a set second threshold, judging that the corresponding infrared geminate transistor is shielded. According to the infrared touch screen and the coverage detection method and system thereof provided by the invention, the state data of the touch screen can be obtained, including whether the touch screen is in a contracted hidden state or an unfolded use state, so that the touch screen can be intelligently controlled subsequently.

Description

technical field [0001] The invention belongs to the technical field of touch screens, and relates to an infrared touch screen, in particular to an infrared touch screen coverage detection method and system. Background technique [0002] The infrared touch screen includes infrared emitting and receiving sensing elements installed on the outer frame of the touch screen. On the surface of the screen, an infrared detection network is formed. Any touching object can change the infrared rays on the contacts to realize the touch screen operation. The realization principle of the infrared touch screen is similar to that of the surface acoustic wave touch screen, which uses infrared emitting and receiving sensing elements. These elements form an infrared detection network on the surface of the screen, and the touch-operated object (such as a finger) can change the infrared rays of the touch point, which is then converted into the coordinate position of the touch to realize the respon...
