Abstract

This invention discloses a double display organic electroluminescence device. It contains at least one transparent conductive glass anode, a cathode opposite with anode and organic luminescence layer between said transparent conductive glass anode and cathode and applied with voltage to be excited to emit light, the said cathode is made of transparent conductive glass, so the double surface display of organic electroluminescence device is realized.

Description

(1) Technical field [0001] The present invention relates to an organic electroluminescent (Organic Light-Emitting Diode; OLED) device, and more particularly relates to an organic electroluminescent device capable of double-sided display. (2) Background technology [0002] Compared with the Liquid Crystal Display (LCD) which is gradually becoming the mainstream at present, the Organic Light-Emitting Diode (OLED) device has a great advantage: in terms of volume, since the OLED itself emits light, it does not Requires backlight and external lighting resources, so it is lighter than LCD. Generally, the thickness of an OLED panel is about 1mm to 2mm, which is usually one-third of the ordinary color LCD, and half thinner than most black and white LCDs. It can easily create a display of 3mm to 4mm. Moreover, OLED has excellent The flexibility, which can be folded and bent, makes its application range very wide; in terms of viewing angle, due to the different light sources of OLED ...
