Abstract

The present invention provides a touch identification method and display apparatus based on an infrared touch screen, and relates to the field of the infrared touch screen technologies, so as to resolve problems of inaccuracy of a touch point determined by a current touch identification method and touch failure. The method comprises: driving a launch tube at a first direction side of the infrared touch screen to scan, acquiring at least one first touch point, and storing at least one first touch point; driving a launch tube at a second direction side of the infrared touch screen to scan, and acquiring at least one second touch point; matching the at least one second touch point with the at least one first touch point, and determining at least one matching pair; and for any matching pair of the at least one matching pair, combining a coordinate value corresponding to the second direction side of the second touch point with a coordinate value corresponding to the first direction side of the first touch point in the matching pair, determining that a combined coordinate is the touch point on the infrared touch screen, and outputting the touch point.

Description

technical field [0001] The invention relates to the technical field of infrared touch screens, in particular to a touch recognition method and a display device based on an infrared touch screen. Background technique [0002] The infrared touch screen is a display screen that uses a horizontally and vertically dense infrared matrix to detect and locate the user's touch. E.g, figure 1 It is a schematic diagram of the structure of the infrared touch screen, such as figure 1 As shown, the infrared touch screen has a rectangular structure, and an array of infrared tubes is installed on the frame around the infrared touch screen. The array of infrared tubes includes one-to-one corresponding infrared emitting tubes and infrared receiving tubes. The infrared receiving tube emits scanning light, when there is a touch point inside the infrared touch screen (such as figure 1 When the black dot in ), the touch point will block the two infrared rays passing through the position (such ...
