The invention provides a display panel and a display apparatus. The display panel comprises a first substrate and a second substrate which are arranged oppositely, a first electrode located on one side of the first substrate, a second electrode located on one side of the second substrate, and a plurality of compressible support objects located between the first electrode and the second electrode, wherein a dielectric constant of each compressible support object is changed with change of a compression amount of the compressible support object; and projection of the compressible support objects, the first electrode and the second electrode in a direction perpendicular to the first substrate has an area in which the compressible support objects, the first electrode and the second electrode are overlapped. When a user presses the display panel, the compressible support objects in the pressed position are directly compressed; and the compression amount of the compressible support objects in the pressed position is greater than an overall deformation amount of the display panel, namely, a capacitance value change caused by the compression amount of the compressible support objects is greater than that caused by the overall deformation amount of the display panel, so that the pressure detection sensitivity of the display panel and the display apparatus provided by the invention is relatively high.
Description
technical field [0001] The present invention relates to the technical field of display devices, and more specifically, to a display panel and a display device. Background technique [0002] At present, touch display screens are more and more widely used in electronic devices. In order to further meet the needs of users, a touch display panel is disclosed in the prior art, and the touch display panel can detect the magnitude of the touch pressure when the user touches the display screen. [0003] Such as figure 1 as shown, figure 1 It is a schematic cross-sectional structure diagram of an existing touch display panel, which includes a first substrate 10 and a second substrate 11 disposed opposite to each other and a liquid crystal layer 12 between the first substrate 10 and the second substrate 11 , wherein the side of the first substrate 10 facing the second substrate 11 has a pressure driving electrode 101 , and the side of the second substrate 11 facing the first substr...
