AI Technical Summary

Technical Problem

Existing display devices are prone to generating high-frequency noise and heat when the touch module vibrates, due to friction between the touch module and the module frame and the display module. This affects the user experience and may also suppress the vibration amplitude of the touch sensor, reducing the intensity of touch perception.

Method used

The touch module is isolated from the module frame and the display module by a first isolation structure and a second isolation structure with a low Young's modulus, respectively, maintaining a certain distance to avoid friction-induced noise and heat. At the same time, the touch module is not completely fixed to ensure that the vibration amplitude does not decrease significantly.

Benefits of technology

It effectively reduces the generation of high-frequency noise and heat, improves the user experience, and maintains the intensity of tactile perception and the vibration effect of the tactile sensor.

Abstract

The display device provided by the present disclosure adopts a first isolation structure to isolate the touch module and the module frame, so that a certain distance is maintained between the touch module and the module frame, and a second isolation structure is adopted to isolate the display module and the touch module, and a certain distance is maintained between the display module and the touch module, so that high-frequency noise and heat generated by friction between the touch module and the display module and the module frame are avoided, and the user experience is affected. Moreover, the first isolation structure and the second isolation structure do not completely fix the touch module, so that the vibration of the touch module during the operation of the tactile sensor is not greatly inhibited, that is, the intensity of the tactile perception can be effectively ensured without reducing the vibration amplitude of the touch module.
