Problems solved by technology

Organic light-emitting diode display devices with RGB-SBS structure cannot reach the current efficiency and service life level of Tandem structure
The manufacturing process of the Tandem structure needs to double the evaporation chamber on the basis of the manufacturing process of the SBS structure, which increases the complexity of the process and the production cost, which is not conducive to mass production.

Abstract

The invention provides an organic light emitting diode display device. The organic light-emitting device comprises an anode layer, a cathode layer and a light-emitting layer arranged between the anodelayer and the cathode layer; the light-emitting layer comprises a first light-emitting layer and a second light-emitting layer which are arranged in a stacked mode; the first light-emitting layer comprises a first color light-emitting part, a second color light-emitting part and a third color light-emitting part which are arranged on the same layer; the second light-emitting layer is used for emitting light of a first color; and the second light-emitting layer is located on one side of the first light-emitting layer and covers the first light-emitting layer.

Description

technical field [0001] The present application relates to the display field, in particular to an organic light emitting diode display device, a manufacturing method thereof and a display panel. Background technique [0002] Currently, OLED (Organic Light-Emitting Diode) display devices used in vehicles mainly include red, green, and blue pixel juxtaposition (RGB-SBS, RGB Side By Side) and stacked (Tandem) structures. The organic light emitting diode display device of the RGB-SBS structure cannot reach the current efficiency and service life level of the Tandem structure. The manufacturing process of the Tandem structure needs to double the evaporation chamber on the basis of the manufacturing process of the SBS structure, which increases the complexity of the process and the production cost, which is not conducive to mass production. Contents of the invention [0003] In view of this, the purpose of the present application is to provide an organic light emitting diode dis...
