Abstract

The invention relates to an infrared touch technology, and particularly discloses an infrared touch frame high-density scanning method and circuit, a touch frame and electronic equipment, and the method comprises the steps: enabling a controller to control an emitter of the infrared touch frame to sequentially send an infrared signal to each corresponding group of receivers for scanning; the controller determines coordinates of the occlusion area. According to the infrared touch frame high-density scanning method, high-precision and rapid scanning can be carried out, and the problem that a traditional scanning mode is long in time is solved.

Description

technical field [0001] The invention relates to infrared touch technology, in particular to an infrared touch frame high-density scanning method, circuit, touch frame and electronic equipment. Background technique [0002] Now that the touch screen technology is widely used, the scanning method related to the touch screen is becoming more and more important, and its scanning speed affects the recognition accuracy of the touch point on the touch screen to a great extent. [0003] Usually, infrared emitting tubes and infrared receiving tubes are closely arranged on the frame of the infrared paired tube touch screen, and the touch point is identified by scanning whether the infrared paired tube is blocked. Existing scanning methods mainly include global scanning and regional scanning, wherein global scanning is full lamp scanning, and in each scanning cycle, all pairs of lamps are scanned at least one scanning angle, and one time is completed The scanning process of touch poin...
