Abstract

The invention discloses a touch stimulation device, and a touch display device and a driving method therefor. The touch stimulation device includes a protection film, a substrate film, a driving chip, a plurality of heating units, and a plurality of shape-changeable particles; the protection film and the substrate film are arranged oppositely; the plurality of heating units are arranged one side facing the protection film, of the substrate film, and heating surfaces of the heating units face the protection film; the plurality of shape-changeable particles are added between the heating units and the protection film; and the plurality of heating units are electrically connected to the driving chip which can control power-on / power-off of the heating units. The protection film and the substrate film are arranged oppositely, the plurality of heating units and the plurality of shape-changeable particles are arranged between the protection film and the substrate film, the shape-changeable particles are close to the protection film, and the heating units are close to the substrate film; power-on / power-off of the heating units are controlled by the driving chip; and during a touch control operation, microcosmic deformation of a surface of the protection film can provide abundant touch experiences for a user.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch stimulation device, a touch display device and a driving method thereof. Background technique [0002] With the rapid development of display technology, touch panels (Touch Panel) have gradually spread in people's lives. Compared with traditional displays that can only provide display functions, displays using touch screens can enable information interaction between users and the display control host. Therefore, touch screens can completely or at least partially replace common input devices, making existing displays Not only can display, but also touch control. [0003] Common touch screens are divided into resistive touch screens, capacitive touch screens, electromagnetic touch screens, and infrared blocking touch screens. Capacitive touch screens are most widely used in existing electronic terminals. Capacitive touch screens work by using the current ind...
