Problems solved by technology

[0004] However, since the aperture ratio of OLED display devices with bottom-emitting OLED devices is limited by opaque structures such as TFT (Thin Film Transistor, thin film transistors), it is difficult for emissive OLED display devices to achieve high-resolution display requirements. Therefore, OLED display devices with top-emitting OLED devices are mostly used in the prior art
However, in the top-emitting OLED device, the light needs to be emitted from the cathode side, so the thickness of the cathode needs to be prepared thinner, resulting in excessive cathode resistance and voltage drop.
[0005] In addition, in the Integrated-touch-driver (ITD for short) technology, it is difficult to further realize the ultra-thinning of the ITD display device because touch electrodes need to be provided in the OLED display device.

The display panel includes: a base substrate; a light-emitting device layer arranged above the base substrate; a touch control structure layer arranged on the side of the light-emitting device layer away from the base substrate; the light-emitting device layer includes multiple A light-emitting device, the light-emitting device includes: a first electrode, a light-emitting functional layer, and a second electrode arranged away from the base substrate in sequence; the touch structure layer includes: a plurality of third electrodes; a plurality of the first electrodes At least one of the third electrodes among the three electrodes is in contact with the second electrode.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Compared with liquid crystal display devices, OLED (Organic Light-Emitting Diode) display devices have advantages such as self-illumination, fast response, wide viewing angle, high brightness, bright colors, and thinness, and are considered to be the next generation display technology. According to the different light emitting directions, the self-luminous elements in OLED display devices, that is, OLED devices, can be divided into bottom emission type (or called bottom emission type, that is, emitting light downward relative to the substrate) and top emission type (or called top emission type). type, that is, emit light upward relative to the substrate) two types. [0003] In traditional technology, OLED devices usually adopt the bottom emission type, in which the light emitted...
