Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Please refer to Fig. 3, the double-sided display organic electroluminescent (Organic Light-Emitting Diode; OLED) device 50 of the present invention includes at least one transparent conductive glass (Indium-Tin Oxide; ITO) anode 52, one is opposite to this transparent ITO anode The transparent ITO cathode 57, and the organic light emitting layer (Emitting Layer; EML) 55 disposed on the ITO anode 52 and the ITO cathode 57.

[0022] The double-sided display OLED device 50 further includes a hole injection layer (Hole Injecting Layer; HIL) 53 and a hole transporting layer (Hole Transporting Layer; HTL) 54 disposed between the ITO anode 52 and the organic light-emitting layer 55, Wherein the hole injection layer 53 is adjacent to the ITO anode, the hole transport layer is adjacent to the organic light emitting layer 55; the electron transporting layer (Electron Tr...

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 ...
