Embodiment

[0021] Figure 5An example of a top-emitting PLED according to the present invention is shown. The flexible substrate 1 consisted of a 125 micron thick PET sheet 1a laminated to a 25 micron thick aluminum foil 1b. A 120 nm thick transparent ITO anode 2 was formed on the plastic side of the flexible substrate 1 . On top of the ITO anode 2 is a bilayer organic stack 3 comprising an 80nm thick emissive layer 3a made of polyphenylenevinylene (Ph-PPV), and an emissive layer 3a made of polyethylenedioxythiophene (PEDOT). A 30 nm thick hole transport layer 3b was formed. The relatively transparent cathode 4 is a multilayer structure comprising, from the top, a layer 4a of tris-(8-quinoline)aluminum (Alq3) 52 nm thick, a layer 4b of translucent Ag 15 nm thick, and a layer 4b of 1.0 nm thick Calcium (Ca) layer 4c, and 0.6 nm thick lithium fluoride (LiF) layer 4d. In this case, Alq3 is provided as an index matching layer, Ag is provided as a conductive layer providing lateral conduc...

Abstract

The invention relates to an organic light-emitting-diode (OLED) formed on an opaque flexible baseboard which comprises one of the following materials: 1.laminated or metal-coated plastic layer; 2.metal layer sandwiched between two layers of plastic and or 3.metal foil. When OLED is formed on the metal surface of the flexible baseboard, the metal surface is coated with insulation layer which can be spin coated polymer or dielectric layer. The metal in the flexible baseboard as obstruct layer makes oxygen and vapor impregnate the OLED to minimum. Otherwise, as the OLED has opaque or semi-opaque upper electrode, the light can be passed through the upper electrode.

Description

technical field [0001] The present invention generally relates to organic electroluminescent components, and particularly relates to a flexible organic light emitting component (OLED). Background technique [0002] Recently, organic light-emitting devices (OLEDs) have attracted attention as a display device. OLEDs can replace liquid crystal displays (LCDs) because OLEDs can generate visibility through self-illumination. Therefore, they do not require backlighting (back-lighting) required by LCDs. Therefore, they can be Made into light, thin and flexible displays. A typical OLED is constructed by placing an organic luminescent material between a cathode layer that can inject electrons and an anode layer that can inject holes. When a voltage of appropriate polarity is applied between the cathode and the anode, holes injected from the anode combine with electrons injected from the cathode to release energy as light, thereby generating electroluminescence. Polymeric electrolum...
