Abstract

The invention provides an infrared touch display screen and a touch method thereof. The infrared touch display screen comprises a display panel, a tactile feedback device and an infrared touch screen, wherein the tactile feedback device comprises a substrate, a first transparent electrode, a first insulating layer, multiple spacers, a second transparent electrode and a PEN membrane, and when an electric signal is applied to the first transparent electrode and the second transparent electrode, the PEN membrane is deformed. According to the infrared touch display screen and the touch method thereof, by applying the electric signal to the first transparent electrode and the second transparent electrode, the insulating layer is polarized under the action of a strong electric field, therefore, polarization charges are generated on the surface of the insulating layer, and the polarization charges generate a corresponding electrostatic field; under the action of the electrostatic field, corresponding inductive charges are generated on the surface of the PEN membrane, electrostatic force is generated between the polarization charges and the inductive charges, the PEN membrane is deformed under the action of the electrostatic force, and then the reality sense of man-machine interaction is achieved.

Description

technical field [0001] The invention belongs to the field of tactile feedback, and in particular relates to an infrared touch screen and a touch method thereof. technical background [0002] In the touch market, resistive and capacitive touch panels have always been the mainstream in the market, but the cost of capacitive touch panels increases exponentially with size, which still greatly limits its application in the large touch screen equipment market. [0003] The infrared matrix touch technology based on optics has gradually surfaced, and the infrared touch screen does not need to attach a layer of glass to the capacitive screen, thereby enhancing the light transmittance, and the infrared touch screen is not affected by current, voltage and static electricity, and is suitable for harsh environments. environmental conditions. Infrared Touch Screen Technology (Infrared Touch Screen Technology) is composed of infrared emitting and receiving sensing elements installed on th...
