Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0044] As mentioned in the background, with the development of portable electronic display devices, touch display devices provide a new human-computer interaction interface, which is more direct and humanized in use. Currently, the OLED touch display device is usually made by separating the OLED display screen and the touch screen, and then combining the two. The OLED touch display device with an external touch screen has disadvantages such as low light transm...

Abstract

The invention discloses a display panel and a display apparatus The display panel comprises a substrate and an anode layer and a cathode layer, arranged on the same side of the substrate and disposed oppositely along the direction perpendicular to the substrate, wherein the anode layer is arranged between the substrate and the cathode layer and comprises a plurality of anodes. The display panel also comprises a pixel drive circuit electrically connected with the anodes. In a display phase, the pixel drive circuit transmits driving current to the anodes. In a touch control phase, the pixel drive circuit controls the anodes to float. The display panel also comprises a touch control induction electrode layer arranged on the side, away from the anode layer, of the cathode layer. In the touch control phase, the cathode layer multiplexes as a touch control driving electrode layer. In the touch control phase, the anodes in the display panel are controlled to be floating, and the cathode layer multiplexes as a touch control driving electrode layer so that to cooperatively form a touch control detection structure with the touch control induction electrode layer. No externally hung touch screen is needed for the display panel, the light transmittance of the display apparatus is improved, the thickness of the display apparatus is reduced, and the trend of making the display apparatus light and thin is met.

Description

technical field [0001] The present invention relates to the technical field of touch display, and more specifically, to a display panel and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED, Organic Light-Emitting Diode) display technology, as a display technology with great development potential, is widely used in the field of high-performance display. Compared with liquid crystal display technology, since the self-luminous mode of each pixel is used instead of the backlight mode, it has the advantages of large viewing angle, low power consumption, high contrast, thin screen thickness, fast response time, and high luminous efficiency. [0003] With the development of portable electronic display devices, touch display devices provide a new human-computer interaction interface, which is more direct and humanized in use. Currently, the OLED touch display device is usually made by separating the OLED display screen and the touch screen, and the...
