Abstract

The invention provides a double-sided OLED display device and the manufacturing method for the same. The double-sided OLED display device is provided with a transparent anode (21), a reflection anode (22) covering some parts of the transparent anode (21), a transparent cathode (61), and a reflection cathode (62) covering some parts of the transparent cathode (61) wherein the reflection anode (22) and the reflection cathode (62) work together to block the light emitting layer (4) completely; the reflection anode (22) and the reflection cathode (62) are partially superposed at most in the vertical direction of the arrayed substrate (1) perpendicular to the reflection anode (22) and the reflection cathode (62) so that the light emitted from the light emitting layer (4) can be emitted out from one side of the transparent anode (21) and one side of the transparent cathode (61). In this manner, double-sided display is realized; and the problems of an existing double-sided OLED display device structure can be solved, such as relatively heavy structure, complicated technology and high manufacturing cost.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a double-sided OLED display device and a manufacturing method thereof. Background technique [0002] In the field of display technology, flat panel display devices such as liquid crystal display (Liquid Crystal Display, LCD) devices and organic light-emitting diode (Organic Light-Emitting Diode, OLED) display devices have gradually replaced CRT displays. [0003] OLE display devices have the characteristics of self-illumination, high brightness, fast response speed, wide viewing angle, low power consumption, and flexible display. They are known as "dream displays" and have been favored by major display manufacturers. The main force of the third generation display devices in the field. [0004] OLED display devices usually include sequentially stacked substrates, anodes, hole transport layers, light-emitting layers, electron transport layers, and cathodes. The principle of light...
