摘要:
The present invention discloses a phenanthrene derivative having the following structure: wherein Ar1 and Ar2 independently are phenyl, nathphyl, heterocyclic group, polycyclic aromatic or polycyclic heterocyclic group with at least one conjugated substituent. The conjugated substituent can be an electron withdrawing group or electron donating group. The phenanthrene derivatives have semiconductor properties of electron transfer, electroluminescence (EL), and photoluminescence (PL). Intermolecular stacking can be avoided and electron-luminescent emission stability is enhanced when the derivatives are applied as a light-emitting material in organic EL devices due to the presence of the two stereo cyclopentane rings, such as a host compound or a dopant emitting blue light.

A full-color organic electroluminescence (OEL) display panel includes a substrate and a plurality of full-color OEL pixel devices in a matrix form as a display frame. Each of the pixel devices is composed of a plurality of sub-pixel regions, corresponding to R, G or B colors.

A method of fabricating a color organic electroluminescent display involves forming cathode electrodes on a substrate, and forming a first organic semiconductor layer having an electron-injection transporting property on the cathode electrodes. Solutions containing organic light-emitting material that can dissolve portions of the first organic semiconductor layer are patterned on the first organic semiconductor layer. Then, a solvent in the solutions is removed to form regions having second organic semiconductor layers and mixed organic semiconductor layers, wherein the second organic semiconductor layers are formed on the first organic semiconductor layer and are mostly composed of the organic light-emitting material, and the mixed organic semiconductor layers, composed of the organic light-emitting material and material constituting the first organic semiconductor layer, are embedded in the first organic semiconductor layer. Anode electrodes are formed over the first and second organic semiconductor layers. The present invention also provides a color organic electroluminescent display.

An organic electroluminescent stereoscopic image display apparatus includes a parallax layer and an organic electroluminescent device. The parallax layer is sited on the emission side of the organic electroluminescent device. The parallax layer transfers lights that are received by the right eye and left eye to be lights with different characteristics. A microretarder layer or a micropolarizer layer can be used as the parallax layer. The distance between the parallax layer and the organic electroluminescent device is minimized. So the view angle of the stereoscopic image display apparatus is increased.

A method of manufacturing a full-color organic electro-luminescent device on an indium-tin-oxide glass substrate. A pattern is formed on the indium-tin-oxide glass substrate by the photolithography and the etching process. The indium-tin-oxide glass substrate is cleaned. An insulation pad is formed over the indium-tin-oxide glass substrate. A low shadow mask and a high shadow mask are sequentially formed over the insulation pad by conducting dry film photo-resist processes. A hole-transport layer is formed over the indium-tin-oxide glass substrate by conducting a vapor-depositing process. Three vapor-depositing processes are simultaneously conducted to form red, green and blue light-emitting layers on the hole-transport layer using the low shadow mask and the high shadow mask as a barrier. An electron-transport layer and a metal layer are serially formed over the light-emitting layers by conducting vapor-depositing processes.
