Embodiments of the present invention provide a touch point identification method and apparatus, and a display device, which relate to the technical field of electronics, and can reduce or eliminate delay errors to reduce the phenomena of touch point loss and line breakage. The method comprises: driving an optical path emitting structure on a touch screen in a horizontal edge direction and a vertical edge direction to complete a scanning period, wherein a plurality of scanning angles are formed in the vertical edge direction, and a plurality of scanning angles are formed in the horizontal edge direction; determining one direction with most touch areas, detected in the horizontal edge direction or the vertical edge direction as a benchmark direction, and the other direction as a reference direction; acquiring M intersections Mi of the touch areas in m scanning directions of the benchmark direction, and acquiring N intersections Nj of the touch areas in n scanning directions of the reference direction, wherein each scanning angle corresponds to a scanning direction, i is more than 0 and less than or equal to M, and j is more than 0 and less than or equal to N; and determining touch points according to the intersections W1 of Mi and Nj. The method and the apparatus provided by the embodiments of the present invention are used for touch point identification.
Description
technical field [0001] Embodiments of the present invention relate to the field of electronic technology, and in particular, to a touch point recognition method and device, and a display device. Background technique [0002] A touch screen is an electronic system that can detect the presence and location of a touch within a display area, which simplifies the method of human-computer interaction. In the current touch technology, infrared touch technology has the advantages of strong environmental adaptability, longer life, and more identifiable touch points. The appearance of the infrared touch screen is a rectangular structure, which consists of a long transmitting side and its corresponding long receiving side, a short transmitting side and its corresponding short receiving side. There are several infrared emitting devices on the transmitting side, and there are correspondingly several infrared receiving devices on the corresponding receiving side. Usually, one-to-many sca...
