Abstract

The invention provides a touch display panel and a touch feedback method thereof. The touch feedback method comprises inducing a touch operation on a touch display panel and obtaining position information of one or a plurality of touch points which are corresponding to the touch operation; selecting at least two vibration sources in a plurality of vibration sources and obtaining starting moments and duration time of the at least two vibration sources according to the position information of the touch points and the position information and the number of the vibration sources; starting the at least two selected vibration sources and enabling vibration waves sent from the at least two selected vibration sources to be superposed in the touch points, wherein the superposed amplitude is larger than the amplitude before superposition. According to the touch feedback method, the touch position of the touch display panel can be accurately fed back, the man-machine interaction effect can be improved, and the user usage experience is improved.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction based on touch operation, in particular to a touch display panel and a touch feedback method thereof. Background technique [0002] At present, due to the advantages of simplicity and convenience of touch operation, the application range of terminals with touch display panels is becoming more and more extensive, especially the application range in electronic products is rapidly developing from small-size to large-size. [0003] Compared with the traditional physical button operation, which uses the finger to sense whether the button has been pressed for feedback, the feedback of the touch operation is different. In the prior art, the touch operation is fed back through vibration. The principle is to form a vibration wave on the touch display panel, and the vibration wave is transmitted along the surface of the touch display panel. When the finger touches the surface, the vibrati...
