Pixel structure and manufacturing method thereof, display panel

Abstract

The embodiment of the present invention discloses a pixel structure and its manufacturing method, and a display panel. The pixel structure includes: a substrate, an anode layer, a first auxiliary light-emitting layer, a light-emitting layer, a cathode layer, and at least one first resistance structure, wherein the light-emitting The layer at least includes a first light-emitting portion and a second light-emitting portion, the first light-emitting portion corresponds to the first sub-pixel, the second light-emitting portion corresponds to the second sub-pixel, and the turn-on voltage of the first sub-pixel is greater than the turn-on voltage of the second sub-pixel Voltage, the first resistance structure is located on the path from the first auxiliary light-emitting layer to the cathode layer and in the vertical direction of the second light-emitting part, at least partially overlaps with the second light-emitting part, does not overlap with the first light-emitting part, and at least one The absolute value of the difference between the resistance value of the first resistance structure and the second light-emitting part and the resistance value of the first light-emitting part is smaller than the first preset value, so as to reduce the color of the display panel including the pixel structure. The crosstalk phenomenon improves the display quality of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel structure and a manufacturing method thereof, and a display panel including the pixel structure. Background technique [0002] At present, OLED (Organic Light Emitting Diode) display devices usually include a plurality of sub-pixels, and adjacent sub-pixels emit light in different colors. For example, OLED display devices in the prior art include a plurality of periodically arranged red sub-pixels, green sub-pixels and blue sub-pixels to achieve different color display. [0003] Such as figure 1 As shown, the OLED display device in the prior art generally includes: a substrate 01: an anode layer 02 located on the surface of the substrate 01, the anode layer 02 is composed of a plurality of anode parts; 02 and the auxiliary light-emitting layer 03 of the substrate 01; the light-emitting layer 04 located on the surface of the auxiliary light-emitting layer 03, th...

[0004] However, when the above-mentioned OLED display device performs pure color display, there is a color crosstalk phenomenon, that is, when the OLED display device displays a pure red picture, there is not only red in the display picture, but also some sub-pixels adjacent to the red sub-pixel. The color of the pixels, such as green or blue, reduces the display quality of the OLED display device
