Abstract

The invention discloses a double-sided electroluminescent display panel and a display device. The display panel comprises a first absorption polarization structure arranged on a first light-emitting face of a transparent EL structure, and a first reflection polarization structure arranged on a second light-emitting face of an EL structure, wherein the homology axis of the first absorption polarization structure and the homology axis of the first reflection polarization structure are perpendicular to each other, the first absorption polarization structure is used for absorbing light of a first wave component and transmitting light of a second wave component, and the first reflection polarization structure is used for transmitting light of the first wave component and reflecting light of the second wave component. Through the common effect of the first absorption polarization structure and the first reflection polarization structure, the intensity of environment light can be weakened when the high emission ratio of self-illumination is ensured, the contrast ratio of the double-sided display panel is increased, the influences of environment light on the double-sided display panel are reduced, and the problem that an existing double-sided display panel is low in contrast ratio due to the transparent EL structure is solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a double-sided electroluminescent display panel and a display device. Background technique [0002] At present, Organic Light-Emitting Diode (OLED) display devices have attracted much attention from the industry due to their application advantages such as self-illumination, no need for a backlight module, light weight, thin thickness, simple structure, and durability. [0003] There are two types of OLED devices: non-transparent and transparent. Non-transparent OLED devices can only emit light from one side. Therefore, when preparing a double-sided OLED display device, it is necessary to bond two independent display devices, or to seal the substrates on which the OLED devices are respectively installed. Therefore, the cost of preparing a double-sided OLED display device using a non-transparent OLED device is relatively high, and the thickness of the double-sided OLED display dev...
