Problems solved by technology

The OLED panel using similar technology has the characteristics of full transparency, but because it transmits light from top to bottom, it also has the defect of low contrast
In addition, there is also the use of independent top-emitting and bottom-emitting OLED devices to achieve the purpose of double-sided display. The display contrast o

Abstract

The invention discloses a double-side display panel and a double-side display device, and the display panel comprises a plurality of pixel units which are arranged in an array, wherein each pixel unitcomprises a thin film transistor, a front display pixel, and a back display pixel. Each front display pixel comprises a first anode, a first light-emitting layer and a first cathode. Each back display pixel comprises a second anode, a second light-emitting layer and a second cathode. The first anodes and the second anodes are electrically connected with the drain electrodes of the thin film transistors. Through the above mode, the number of wires is effectively reduced in a manufacturing process of a panel, and the impact on the pixel density from the excessive wires is reduced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a double-sided display panel and a double-sided display device. Background technique [0002] Organic light-emitting diodes (OLEDs) have the advantages of wide color gamut, high contrast, self-illumination, thinness and foldability, and have attracted extensive attention in the fields of display and lighting applications. [0003] Making double-sided display panels using OLEDs is a trend in OLED applications. The double-sided display technology can effectively expand the display area of ​​the OLED panel and give full play to the thin and light advantages of the OLED panel. Existing double-sided display OLED panels mostly use transparent cathodes and transparent anodes, and a single sub-pixel emits light up and down. The OLED panel using similar technology has the characteristics of full transparency, but because it transmits light from top to bottom, it also has the ...
