AI Technical Summary
Technical Problem
Existing infrared touch devices take a long time to determine the location of the touch point, have slow response speed, and are susceptible to false points.
Method used
The display screen is divided into multiple display areas. By obtaining the energy reference value and energy target value of each display area, sorting it according to the size of the relative energy value, priority is given to the position information of the touch point in the display area with higher relative energy values, and time-consuming positioning operation of false point consumption is reduced.
Benefits of technology
It reduces the time-consuming positioning operation, improves the response speed of infrared touch devices and the accuracy of touch point positions.

Abstract
The embodiment of the invention belongs to the technology of infrared touch equipment, and provides infrared touch equipment and a method for determining the position of a touch point of the infrared touch equipment, the infrared touch equipment comprises an infrared transmitting tube, an infrared receiving tube, a display screen and a processor, and the display screen is divided into a plurality of display areas. The processor is used for obtaining an energy reference value and an energy target value of at least one display area, determining relative energy values corresponding to the display areas according to the energy target values and the energy reference values corresponding to the display areas, sorting the display areas meeting preset conditions according to the relative energy values, and outputting the sorted display areas. Obtaining a to-be-processed display area set, and then determining position information of touch points in the display areas in sequence according to the sequence of the display areas in the to-be-processed display area set. According to the method, time consumed by positioning operation is reduced, and the response speed of the infrared touch equipment is increased.
