The embodiment of the invention discloses a method and a relevant device for determining a touch screen calibrating criterion and touch screen response. In the embodiment of the invention, the method comprises the following steps of: firstly, determining a displaying unit, obtaining a first touch response point by touching the displaying mark points of a first displaying unit, and further then obtaining a first mapping relationship between the displaying mark points of the first displaying unit and the first touch response point; traversing other displaying units excepting the first displaying unit, and then obtaining the touch screen calibrating criterion. In the embodiment of the invention, a group of mapping relationships is obtained by touching the displaying mark points of the displaying unit, and then the touch screen calibrating criterion is obtained by touching the displaying mark points of the various displaying units one by one and independently calibrating the various displaying units; the touch screen calibrating criterion is obtained by using an independent calibrating method, the various displaying units do not influence each other, and major errors cannot be produced while the touch screen is touched.
Description
technical field [0001] The present invention relates to the field of touch technology, in particular to a method for determining a touch screen calibration criterion, a touch screen response and a related device. Background technique [0002] A touch screen is an electronic system that detects the presence and location of a touch within the display area. Among the current touch technologies, infrared touch technology has the advantages of strong environmental adaptability, long life, and more identifiable touch points. Such as figure 1 As shown, the appearance of the infrared touch screen is a rectangular structure, which consists of a long transmitting side 1011 , a long receiving side 1021 , a short transmitting side 1012 , and a short receiving side 1022 . There are several transmitting lights on the long emitting side 1011 and the short emitting side 1012 , and there are correspondingly several receiving lights on the long receiving side 1021 and the short receiving si...
