Abstract

The invention discloses a display device. The display device comprises a first pressure sensing module, a second pressure sensing module opposite to the first pressure sensing module and an elastic component, wherein the elastic component comprises a first end face and a second end face opposite to the first end face; and the first end face is in contact with the first pressure sensing module and the second end face is in contact with the second pressure sensing module to ensure that the elastic component is compressed when the display device is pressed, and then the distance between a first pressure sensing layer and a second pressure sensing layer changes to realize pressure detection. According to the display device disclosed by the invention, the pressing deformation of a display panel in a capacitance change dependence module in the prior art is converted to deformation of the elastic component to be realized, so that the deformation requirement for the display panel is relatively low, or pressure detection also can be carried out on the display panel without deformation, so that the screen breakage probability of a display screen is reduced, the clearance deformation becomes uniform, and the influence on the display is decreased.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] In recent years, with the development of touch display technology, people's expectations for touch screens are not limited to the detection of the touch position, but also hope that the pressing force can be detected when touching, that is, the 3D Touch (Three Dimensional Touch) function can be realized. [0003] In the prior art, the 3D Touch function is realized mainly by pressing the display device, through the deformation of the display panel or the backlight module in the module of the display device, and sensing the capacitance change. However, with the trend of ultra-thin and high-resolution With the rapid development of the display device, the stability of the internal and external structure of the display panel is reduced, and the deformation of the display panel is likely to cause abnormal display, and may even ca...
