Abstract

The invention discloses an organic light-emitting display panel and an organic light-emitting display device. The organic light-emitting display panel comprises a substrate, a cathode layer, an anode layer, a plurality of metal layers and an insulating medium, wherein the anode layer is located between the substrate and the cathode layer; the plurality of metal layers are located between the substrate and the anode layer; the insulating medium is located between the metal layers and the cathode layer; the anode layer comprises an anode region; the cathode layer is multiplexed as a first pressure-sensitive electrode; a second pressure-sensitive electrode is arranged on the metal layer or in a region not overlapping with the anode region of the anode layer; and the first pressure-sensitive electrode, the second pressure-sensitive electrode and the insulating medium located between the first pressure-sensitive electrode and the second pressure-sensitive electrode are used for sensing pressure. The organic light-emitting display panel and the organic light-emitting display device can achieve pressure sensing on the basis of an existing organic light-emitting display panel; the manufacturing cost is reduced; and the thickness of a pressure-sensitive display device is reduced.

Description

technical field [0001] The present application relates to the field of display technology, specifically to the field of organic light-emitting display technology, and in particular to an organic light-emitting display panel and an organic light-emitting display device. Background technique [0002] With the development of display technology, display devices with pressure-sensitive functions are more and more widely used. In existing pressure-sensitive display devices, the realization of the pressure-sensitive function usually requires adding a film structure between the backlight unit of the liquid crystal display and the array substrate, or adding a film structure around the organic light-emitting display to form a pressure-sensitive Capacitance, which converts pressure into changes in piezo-capacitance, so as to detect pressure by sensing the change in piezo-capacitance. [0003] In the process of making the above-mentioned pressure-sensitive display device, it is necessa...
