Abstract

The embodiment of the invention provides a tactile sensing and feedback substrate and a driving method thereof, and the tactile sensing and feedback substrate comprises a sensing and feedback layer which comprises a plurality of sensing and feedback units, each sensing and feedback unit is distributed according to a preset array, and one end of each sensing and feedback unit is connected with a voltage input end; a switching circuit layer which comprises a plurality of switching circuits, and each switching circuit is connected with one sensing and feedback unit and used for being opened or closed under the condition that it is detected that the first current exceeds the preset current so as to control the sensing and feedback unit to achieve vibration feedback. According to the tactile sensing and feedback substrate of the invention, the touch sensing and feedback substrate is improved, and the plurality of sensing and feedback units are distributed on the substrate according to the preset array, so that the vibration feedback is accurately generated at the touch operation position, the global vibration feedback is not carried out like the prior art, the feedback fineness is greatly improved, and the user experience is better.

Description

technical field [0001] The present disclosure relates to the field of displays, in particular to a tactile sensing and feedback substrate and a driving method thereof. Background technique [0002] Many of the current display screens have integrated touch functions, and the positioning function can be realized through touch. The technology used is a capacitive structure. In addition to the touch sensing function, the touch feedback also directly affects the user experience. [0003] At this stage, the touch feedback technology implemented by intelligent electronic devices uses motors, which are specifically divided into eccentric rotor motors and linear resonant motors. These motors are usually large in size, and only a few motors can be placed in each intelligent electronic device, so as to realize the touch feedback of the vibration effect. However, although the touch feedback can be realized through the motor, due to the large size of the motor, only the global vibratio...
