Pixel structure, manufacturing method thereof and display panel

Abstract

The embodiment of the invention discloses a pixel structure, a manufacturing method thereof, 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 resistor structure; the light-emitting layer at least comprises a first light-emitting portion and a second light-emitting portion; the first light-emitting portion corresponding to first sub pixels; the second light-emitting portion is corresponding to the second sub pixels; the turn-on voltage of the first sub pixels is larger than the turn-on voltage of the second pixels; the first resistor structures are located on a closed path from the first auxiliary light emitting layer to the cathode layer and are arranged at the vertical direction of the second light-emitting portion and are at least partially overlapped with the second light-emitting portion, and are not overlapped with the first light-emitting portion; and the absolute value of the difference value between the sum of the resistance values of the at least one first resistor structure and the second light-emitting portion and the resistance value of the first light-emitting portion is smaller than a first preset value, so that color crosstalk which occurs when a display panel comprising the pixel structure performs display can be alleviated, and the display quality of the display panel is improved.

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
