Abstract

The embodiment of the present invention discloses a method for adjusting the accuracy of an infrared touch screen, which is used to solve the problems of human error and difficult quantification in the existing accuracy adjustment method. The method in the embodiment of the present invention includes: when the second external device touches the infrared touch screen, acquiring the coordinates of the center point of the contact area on the infrared touch screen; receiving the response coordinates sent by the first external device, and the response coordinates are determined by the infrared touch screen Generated when the second external device is touched; calculate the deviation parameter of the response coordinate relative to the center point coordinate; transmit the deviation parameter to the first external device, so that when the deviation parameter is not within the preset standard deviation range , the first external device adjusts the precision of the infrared touch screen according to the deviation parameter. The embodiment of the present invention also provides an infrared touch screen precision adjustment device.

Description

technical field [0001] The invention relates to the field of touch screen detection, in particular to a method and device for adjusting the accuracy of an infrared touch screen. Background technique [0002] The scanning technology of the infrared touch screen relies on the interruption of the infrared grating in front of the display screen. The X and Y directions of the touch frame include an array of infrared light-emitting diodes and an array of phototransistors, which are installed relatively parallel in a one-to-one correspondence mode of emission and reception, thereby forming an invisible infrared grating. The touch screen controller makes the diode arrays in the X and Y directions sequentially light up and emit infrared beams. When an obstacle such as a finger enters the beam grid, it blocks the beam, so that one or several photosensitive transistors detect the loss of light. After calculation In this way, the X and Y axis coordinates of the touched point are confir...
