Problems solved by technology

[0005] With the improvement of the resolution of the display panel, more OLED units need to be placed on the display panel of the same size, so that the volume of the OLED unit becomes smaller and smaller. When the anode layer and the electroluminescence unit are aligned It is easy to displace the light-emitting layer and its corresponding pixel area, and the display panel composed of these dislocated OLED units will appear color mixing phenomenon when displaying

Abstract

The invention discloses an OLED (Organic Light Emitting Diode) unit, a manufacturing method of the OLED unit and a display panel and belongs to the technical field of display. The OLED unit comprises a first electrode layer, an electroluminescent unit and a second electrode layer, wherein the electroluminescent unit is located between the first electrode layer and the second electrode layer and comprises at least one luminous layer; each luminous layer corresponds to two pixel areas; the second electrode layer comprises the pixel areas; and each luminous layer is overlapped with the two pixel areas corresponding to a projection area in the second electrode layer. According to the unit, each luminous layer can correspond to the two pixel areas, the quantity of the luminous layers in the OLED unit is reduced, and the area of the luminous layers is increased, so that the alignment difficulty between the luminous layers and the pixel areas is reduced, and a color mixture phenomenon of the display panel is avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED unit, a manufacturing method thereof, and a display panel. Background technique [0002] An OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) unit is an organic diode with self-luminous characteristics, which is an important material for manufacturing a display screen. For example, a display panel is an important component of a display screen, and the display panel is composed of a large number of OLED units. [0003] At present, the structure of an OLED unit includes: an anode layer, an electroluminescence unit, and a cathode layer. The electroluminescence unit is located between the anode layer and the cathode layer. The electroluminescence unit includes a plurality of light-emitting layers. A pixel area of ​​the anode layer, the projected area of ​​the light emitting layer on the anode layer overlaps with the corresponding pixel area of ​​the light em...
