Abstract

The invention provides an organic light emitting diode device and a display device thereof, comprising an anode, a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer and a cathode stacked sequentially from bottom to top, the hole injection layer It is a compound hole injection layer, including stacking the first hole injection layer, the first red light hole injection layer, the second red light hole injection layer, the green light hole injection layer and the green light hole injection layer sequentially from bottom to top. The blue light hole injection layer of the same layer as the light hole injection layer. The present invention can also indirectly reduce the thickness of the single-cavity coating of the blue-light OLED by reducing the thickness of the single-cavity coating or the hole-transporting layer of the hole injection layer of the red-light OLED, thereby avoiding high coating caused by too thick a single-layer film. The problem of high efficiency or long production time effectively shortens the production time and saves evaporation materials.

Description

technical field [0001] The invention relates to the field of display elements, in particular to an organic light emitting diode device with reduced thickness and a display device thereof. Background technique [0002] The common top-emitting organic light-emitting diode (Top-Emitting Active Matrix Organic-Lighting Diode, Top-emitting AMOLED), according to the optical requirements, the thickness of the OLED component is more of the thickness of the red part > the thickness of the green part > the thickness of the blue part The thickness of the injection layer (Injection Layer, IL) or the transmission layer (Transporting Layer, TL) has a high proportion, especially the thickness of the blue and red layers is particularly thick, which will cause bottlenecks and difficulties in production, such as: [0003] (1) The thickness is thick. In order to match the production rhythm (tact time), a high evaporation rate is required, which will also cause more material consumption pe...
