Problems solved by technology

[0006] However, such OLED structures still have many problems
For example, the resonant cavity adjustment layer 150 participates in the transport of charges in the organic functional layer, which reduces the luminous efficiency; one primary color emitted by the light emitting layer 133 is enhanced, while the other primary color is weakened; the display panel composed of OLED elements in the prior art will Big role bias

Abstract

The invention provides a display panel and an OLED element of the display panel. The OLED element comprises a first electrode, an organic functional layer arranged on the first electrode, a second electrode arranged on the organic functional layer, a resonant cavity adjusting layer arranged on the second electrode, wherein the resonant cavity adjusting layer has inhomogenous thickness, and a half-transparent and half-reflecting layer arranged on the resonant cavity adjusting layer. The display panel and the OLED element of the display panel, which are provided by the invention, optimize a resonant cavity effect of the OLED element.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and an OLED element thereof. Background technique [0002] In recent years, OLED (Organic Light-Emitting Diode, organic light-emitting diode) technology has developed rapidly, and has become the most likely prospect technology to replace LCD (Liquid Crystal Display, liquid crystal display). [0003] OLEDs can be classified into red OLEDs, blue OLEDs, green OLEDs and white OLEDs according to the color of their light emission. White OLEDs are mostly made by mixing three colors (red, green, blue) of small molecules, polymers or phosphorescent materials into a multi-layer or single-layer structure. Most white OLEDs adopt a stacked structure or a structure with multiple dopants in a single light-emitting layer. [0004] Specifically, when photons are emitted from the light-emitting layer of the OLED element, destructive or constructive interference will occur in the...
