Abstract

The embodiment of the invention discloses a display panel, an integrated pressure induction display device and a driving method. The display panel comprises a substrate; multiple pixel circuits formed on the substrate; at least a driving line which is electrically connected with the multiple pixel circuits and is reused as a first pressure induction electrode; multiple first electrodes which are formed on the multiple pixel circuits are arranged in one-to-one correspondence with the pixel circuits and are electrically connected with the corresponding pixel circuits; and organic light-emitting layers and second electrodes formed on the first electrodes. The second electrodes are multiplexed as multiple second pressure detection electrodes; and the first pressure induction electrode and the second pressure detection electrodes are used for detecting a pressure induced by the display panel. By utilizing the technical scheme of the invention, the thickness of the organic light-emitting display panel with a pressure detection function can be reduced, and the manufacturing cost of the organic light-emitting display panel can be lowered.

Description

technical field [0001] Embodiments of the present invention relate to a touch pressure detection technology, and in particular, to a display panel, a display device integrated with pressure sensing, and a driving method. Background technique [0002] Organic light emitting display (Organic light emitting display), because of its technical advantages such as no need for backlight, high contrast ratio, thin thickness, wide viewing angle, and fast response speed, has become one of the key directions for the development of the display industry. [0003] At present, in order to further expand the application range of the organic light emitting display panel so that it has a touch pressure detection function in addition to the image display function, an additional touch pressure detection device is usually added to the organic light emitting display panel. Undoubtedly, this will increase the thickness of the organic light-emitting display panel, which is contrary to the developmen...
