[0047] Different from the first embodiment, the location of the antireflection layer 22 in this embodiment is different. In this embodiment, the antireflection layer 22 is arranged between the anode layer 231 and the hole injection layer 2321, wherein the antireflection layer 22 The refractive index of the hole injection layer 2321 is lower than that of the hole injection layer 2321. In one embodiment, the refractive index of the hole injection layer 2321 ranges from 1.5 to 1.8, and the refractive index of the antireflection layer 22 ranges from 1.2 to 1.4.

[0048] The manufacturing process of the OLED display panel 20 of this embodiment is basically the same as that of the first embodiment, but it is different from the first embodiment. After 231 is prepared, the antireflection layer 22 is fabricated, and then the hole injection layer 2321, the hole transport layer 2322, the light emitting layer 2323, the electron transport layer 2324, the electron injection layer 2325, the ...

Abstract

The invention discloses an OLED display panel and an OLED display device. The OLED display panel comprises a device layer, an organic light-emitting layer arranged on the device layer, and an encapsulation layer covering the organic light-emitting layer, wherein the device layer and the encapsulation layer At least one anti-reflection layer is also included between them. In the present invention, the refractive index of the anti-reflection layer is low, which can reduce the total reflection angle of the light emitted by the organic light-emitting layer, so that most of the light emitted by the organic light-emitting layer is emitted in the same direction, without adding additional In the case of the transparent area, the brightness of the transparent display of the display panel is improved, and the aperture ratio of the display panel is also increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and an OLED display device. Background technique [0002] Organic light emitting diodes (organic light emitting diode, OLED) have many excellent characteristics such as self-illumination, low energy consumption, wide viewing angle, fast response, etc., and the panels made of OLEDs have the characteristics of simple structure and bendability. The industry is of great interest and is considered to be a very promising next-generation display technology. Transparent display is also a major direction of display technology development due to its application prospects in 3D display, vehicle display and other fields. [0003] At present, the pixels where the OLED devices used for transparent display are located are opaque, and a transparent display is realized by leaving a transparent area between pixels. However, the display panel formed by the aforementioned OL...
