Abstract

The invention discloses a touch screen scanning method and apparatus. The method comprises the steps of determining a historical touch point of a touch operation in a touch screen; outwards extending the historical touch point for a set length according to a preset basic scanning direction to form a reference region; performing scanning according to the basic scanning direction in a scanning period, and determining a quasi touch region of the touch operation; removing false touch regions according to the position of the quasi touch region relative to the reference region, and locating a true touch region; and determining a touch point position, corresponding to the touch operation in the scanning period, in the true touch region through scanning of other scanning directions in the scanning period. Before scanning of other scanning directions, part of the false touch regions are removed, then the closer false touch regions in the reference region are further removed according to other scanning directions, and finally the touch point position is determined. The number of light paths in the scanning process is greatly reduced, the scanning time is correspondingly shortened, and extra scanning and operation time is shortened.

Description

technical field [0001] The present disclosure relates to the field of touch technology, and in particular to a touch screen scanning method and device. Background technique [0002] The touch screen is used to interact with the user by detecting the presence and position of a touch within the display area. For example, in a touch screen, a user only needs to touch a displayed graphic or text with a finger to realize a desired touch operation. [0003] Among the existing touch screen applications, infrared touch screens are more widely used due to their advantages of strong environmental adaptability, longer service life, and more identifiable touch points. [0004] Most infrared touch screens have a rectangular structure, which includes a display screen and a touch frame arranged on the display screen, and the touch frame includes a transmitting side and a receiving side. Specifically, in the touch frame, the long-side transmitting side and the long-side receiving side are...
