Abstract

The application discloses a deformation unit, a display panel, and a driving circuit for tactile feedback. The deformation unit for tactile feedback includes a substrate, a deformation member, and an electrode. The deformation member is located on the substrate. One end of the deformation member is fixedly connected to the electrode, and the other end is a free end. Under the action of the electrode, the deformation member is deformed, and the deformation member Using graphene material.

Description

technical field [0001] The present disclosure generally relates to the technical field of tactile feedback, and in particular, relates to a deformation unit, a display panel and a driving circuit for tactile feedback. Background technique [0002] Now more and more researchers are devoted to the research of tactile feedback technology, and have developed a variety of feedback technologies for two-dimensional screens, mainly including deformation, electrostatic force, vibration, electrical stimulation, piezoelectricity, etc. The tactile feedback device provides the user with effective tactile stimulation corresponding to the displayed object according to the position of the user's finger; the rendering and generation algorithm extracts the image texture of the display interaction interface, maps it with the interaction model of the hand to obtain the driving signal, and sends it to the tactile feedback device to generate the stimulus Complete the rendering of tactile informat...
