Abstract

The invention relates to infrared touch technology, and specifically discloses a high-density scanning method for an infrared touch frame, a circuit, a touch frame and electronic equipment. The signal is scanned; the controller determines the coordinates of the masked area. The high-density scanning method of the infrared touch frame of the present invention can perform high-precision and fast scanning, and avoids the problem of long time in traditional scanning methods.

Description

technical field [0001] The invention relates to infrared touch technology, in particular to a high-density scanning method, circuit, touch frame and electronic equipment of an infrared touch frame. Background technique [0002] Nowadays, the touch screen technology is widely used, and the scanning method involving the touch screen is more and more important, and the scanning speed greatly affects the recognition accuracy of the touch point on the touch screen. [0003] Usually, the infrared emitting tube and the infrared receiving tube 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 has any obstructions. Existing scanning methods mainly include global scanning and area scanning, wherein the global scanning is full lamp scanning. The scanning process of touch point recognition is called a scanning cycle; the sending and receiving of a pair of infrared tubes is called sc...
