Problems solved by technology

[0002] Existing display panels only have a display function. If you want to increase the pressure touch function, you need to add a pressure touch unit. There will be a certain air gap between the force-sensing conductive layer and the middle frame in the existing display panel to form capacitance
The capacitance is sensitive to the distance between the force-sensing layer and the middle frame, and a slight deformation will cause a large change in capacitance, which seriously affects the realization of the touch function.
[0003] For example, when the mobile terminal falls or receives a collision, the air gap between the force-sensing conductive layer and the middle frame will change, and the touch function may fail
