Infrared touch screen scanning method and device and electronic equipment

Abstract

The invention provides an infrared touch screen scanning method and device and electronic equipment, and belongs to the field of touch control. The method comprises the steps that infrared transmitting tubes on a touch screen are partitioned, a plurality of transmitting tube regions are obtained, each transmitting tube region comprises at least one infrared transmitting tube, each infrared transmitting tube corresponds to one transmitting coverage region and one scanning receiving region, and the transmitting coverage regions are different from the scanning receiving regions; the emission coverage area of the first infrared emission tube at the specified position in any emission tube area is not overlapped with the scanning receiving area of the second infrared emission tube at the specified position in the emission tube area adjacent to the emission tube area; performing infrared scanning on each at least two transmitting tube areas at the same time to obtain scanning data; and processing scanning data obtained after infrared scanning to obtain coordinate information of the touch point. According to the method, the infrared touch scanning speed can be increased based on the same physical resolution, so that the touch response speed can be increased, touch points are not prone to being omitted, and the anti-interference capacity of system detection can be enhanced.

Description

technical field [0001] The present application relates to the field of touch control, in particular, to an infrared touch screen scanning method, device and electronic equipment. Background technique [0002] Touch screen, also known as "touch screen" and "touch panel", is an electronic system that can detect the existence and position of touch points in the display area.

Problems solved by technology

[0005] The purpose of the embodiments of the present application is to provide an infrared touch screen scanning method, device, and electronic equipment to solve the problem that it is difficult to balance touch response speed and touch resolution in the existing technology, and to improve the infrared touch scanning based on the same physical resolution. Speed, so as to improve the response speed of touch, but also enhance the anti-interference ability of system detection

In the embodiment of the present application, by partitioning the infrared emission tubes on the touch screen according to the above rules, the infrared emission tubes in each partition are turned on sequentially for scanning without interference, so that multiple partitions can be supported simultaneously without interfering with each other. Scanning, improve the speed of infrared scanning and scanning response speed, so as to solve the problem that the existing technology is difficult to take into account the touch response speed and touch resolution, and can improve the speed of infrared touch scanning based on the same physical resolution
