The display device includes: the display module comprises a light emitting layer group, a first switching driving layer 14 electrically connected with the light emitting layer group and a screen body protective layer 13 arranged between the light emitting layer group and the first switching driving layer 14; a first electrode layer 12 provided between the screen protective layer 13 and the light emitting layer group; a second electrode layer 16 prepared on the first transfer drive layer 14; a touch screen drive layer 15.
The first electrode layer 12, the screen protection layer 13 and the second electrode layer 16 form a pressure sensing capacitor, wherein the screen protection layer 13 serves as an insulating medium layer in the pressure sensing capacitor. When a user presses on the screen body of the display device, the pressure sensing capacitor converts the pressure into an electrical parameter, and then pressure detection is achieved. According to the embodiment shown here, the electrodes in the pressure sensing capacitor and the insulating medium layer between the electrodes are manufactured on the existing structure in the display device, so that the requirement of a full-screen display key is met, the power consumption of the display screen is kept unchanged, and the thickness of the display module is almost reduced. A special circuit is designed on the first switching driving layer 14, and the circuit can connect the outgoing line of the second electrode layer 16 to the corresponding pin of the chip, so that the first electrode layer 12 and the second electrode layer 16 are connected to the chip, and the normal work of the pressure sensing capacitor with the structure is ensured.
In an embodiment of the present invention, the light emitting layer group includes a driving layer 11 and a display light emitting layer (not shown) formed on the driving layer 11, wherein the first transfer driving layer 14 is electrically connected to the driving layer 11, and the first electrode layer 12 is disposed on a surface of the driving layer 11 close to the screen protection layer 13 and has a thin thickness, for example, the thickness may be less than 10 μm, and preferably 4-5 μm. According to this kind of structure, make full use of more the existing membranous layer structure of display module assembly, all structures of forced induction electric capacity have all utilized the existing membranous layer structure of display module assembly, do not increase display module assembly's thickness moreover hardly, when satisfying the full-face screen display button demand, keep display screen consumption and display module assembly thickness all unchangeable. In other embodiments of the present invention, the first electrode layer 12 may also be disposed on the surface of the screen protection layer 13 near the display light emitting layer.
In an embodiment of the present invention, the material of the screen protection layer 13 is an elastic insulating layer material. The screen body protective layer 13 made of the elastic insulating material serves as an insulating medium layer of the pressure sensing capacitor, so that the display device can generate obvious deformation when being subjected to fingers or other applied objects, the distance between the first electrode layer 12 and the second electrode layer is reduced, the pressure sensing capacitor formed by the first electrode layer 12, the insulating medium layer and the second electrode layer is enlarged, and pressure detection is more sensitive.

In the embodiment of the invention, the display luminescent layer and the screen body protective layer 13 jointly serve as an elastic insulating medium layer in the pressure sensing capacitor. Therefore, regardless of whether the screen body protection layer 13 has elasticity, when the display device is under pressure, the distance between the first electrode layer 12 and the second electrode layer is obviously reduced due to the existence of the elastic display luminescent layer, so that the capacitance value of the pressure sensing capacitor formed by the first electrode layer 12, the insulating medium layer formed by the screen body protection layer 13 and the display luminescent layer and the second electrode layer is obviously increased, and the display device is more sensitive to the pressure.

For example, when the first transfer driving layer 14 is a three-layer plate, the second electrode layer 16 may be disposed on a surface of the second film layer or the third film layer of the first transfer driving layer 14 in a direction away from the screen protection layer 13, which is not limited by the present invention.

It will be appreciated that in this case, the first interface drive layer 14 may not need to be electrically connected to the second electrode layer 16.
In an embodiment of the present invention, the second transfer driving layer 10 is made of a flexible material, and can be bent according to the space among the first transfer driving layer 14, the first electrode layer 12, and the screen protection layer 13, so as to fully utilize the space in the display module without increasing the thickness of the display module.
