Abstract
A display panel is disclosed. The display panel includes a back plate, a plurality of pixel units formed on the back plate, and a plurality of deformation units for providing haptic feedback. Each deformation unit is on one or more corresponding pixel units of the plurality of pixel units, and when being applied a drive voltage, undergoes a deformation corresponding to a haptic feature of a visual object displayed by the corresponding pixel units. Thereby, there is provided a display panel with haptic feedback, which is simple in structure and easy to implement.
