Abstract

The invention discloses a double-faced OLED (organic light-emitting diode) display panel and a display device, aiming to solve the problem that external ambient light affects the contrast ratio of the display device after being reflected in the display device by a metal wire. The double-faced OLED display panel comprises a package substrate, an array substrate, a plurality of transparent OLED devices, a first 1 / 4 wave plate, a first polarizer, a second 1 / 4 wave plate and a second polarizer. The package substrate is opposite to the array substrate; each OLED device arranged on the package substrate is positioned between the package substrate and the array substrate, and has a first light emitting direction towards the package substrate and a second light emitting direction towards the array substrate; the first 1 / 4 wave plate and the first polarizer are disposed on the package substrate and are sequentially arranged along the first light emitting direction, and an included angle between optical axes of the first 1 / 4 wave plate and the first polarizer is + / -45 degrees; the second 1 / 4 wave plate and the second polarizer are disposed on the array substrate and are sequentially arranged along the second light emitting direction, and an included angle between optical axes of the second 1 / 4 wave plate and the second polarizer is + / -45 degrees.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a double-sided OLED display panel and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display device has the advantages of self-illumination, no need for backlight module and color filter, light weight, thin thickness, simple structure, durable and other application advantages, so it has been favored by the industry. focus on. [0003] Such as figure 1 The schematic diagram of the principle of the light emission of the OLED shown in the OLED 100 includes a hole injection layer (Hole Injecting Layer, HIL) 101 arranged between the anode (not shown) and the cathode (not shown), the hole transport layer (Hole Transporting Layer, HTL) 102 , organic light-emitting layer (Organic light-emitting layer, OLEL) 103 and electron transporting layer (Electron Transporting Layer, ETL) 104 . Application of a voltage by the...
