ACTIVE DRIVING TYPE VISUAL-TACTILE DISPLAY DEVICE
First Claim
1. An active driving type visual and tactile display device comprising:
- a flat panel display device for visually displaying an image and a haptic part for generating a tactile sense using an electrostatic force, which are integrated, the haptic part comprising unit cells, each of which comprises first to third transistors, a capacitor, and a transparent electrode; and
a detector for generating an electrostatic force between the transparent electrode and the detector when it approaches the transparent electrode of the haptic part, so that the detector senses the electrostatic force to simultaneously recognize visual and tactile information.

Abstract
Provided is an active driving type visual and tactile display device, in which a flat panel display device for visually displaying an image and a haptic part for generating a tactile sense using an electrostatic force are integrated to generate textures according to an electrostatic force based on an image signal. As a result, visual and tactile senses may be simultaneously recognized. Since the display device enables a user to simultaneously see an image through a visual sense and perceive various textures through a tactile sense, the performance of a device is significantly improved. Therefore, various textures according to an image signal can be precisely realized by the generation of an electrostatic force per unit cell.
