Each of the pixel devices is composed of a plurality of sub-pixel regions, corresponding to R, G or B colors.

Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to an organic light-emitting device which provides an electroluminescence (EL) or photoluminescence (PL) device with high external quantum efficiency. The present invention forms a composite film layer with continuously changing refraction indices between an ITO transparent electrode and a substrate made of plastic or glass. The refraction index of the composite film layer is the same as the ITO electrode at the interface with the ITO electrode. It decreases along the direction perpendicular to the substrate in a linear or nonlinear way. The refraction index is the same as that of the plastic or glass at the interface with the substrate. This way can avoid reflection due to the difference in the refraction index across the interface. The excited light originally trapped in the ITO electrode can be guided outwards.

A transparent conductive electrode and an organic luminescent layer are formed in sequence on one of surfaces of the composite layer.

The titanium dioxide-silicon dioxide composite layer and silicon dioxide protecting layer are formed by ion-assisted electron gun evaporation in the temperature lower than 100° C., which does not result in the thermal loading to the small molecule and polymer organic electro-luminescent device.

Abstract: A method for fabricating a full-color organic electro-luminescent device starts with forming an indium tin oxide (ITO) layer on a glass substrate, and then forming a blue-light emitting layer on the ITO layer. By irradiating predetermined portions of the blue-light emitting layer with certain light sources, pixels that emit different light colors are formed on the irradiated portions of the blue-light emitting layer. An electrode layer is then formed on the corresponding pixels, wherein the electrode layer is further covered by a protection layer. During the operation of the full-color OEL device of the invention, a driving voltage is applied on the ITO layer, the anode, and the electrode layer, the cathode.
