  • Publication number: 20070024186
    Abstract: The present invention relates to a color filter conversion apparatus. More particularly, the present invention relates to a color filter conversion apparatus and the application thereof. A color conversion layer, a first photo resist, and a second photo resist are arranged on the substrate. In addition, a first organic light emitting element is arranged on the vertically extended region of the second photo resist and a second organic light emitting element is arranged on the vertically extended region of the first photo resist, the second photo resist and the color conversion layer. Thus, the times for evaporating processes are decreased. Furthermore, the transmittance through the photo resist for the light source produced by the organic light emitting element is raised and the converting efficiency of the color conversion layer can also be enhanced.

  • Publication number: 20070024184
    Abstract: A Full-color organic electroluminescent display device with low power consumption includes a first electrode provided on the surface of a color filter, a first organic light emitting unit for generating a first light and a fourth organic light emitting unit for generating a fourth light respectively provided on the surface of the first electrode. The first light passes through a first photo-resist and filtered for generating a first colored light. And, the fourth organic light emitting unit provides a second photo-resist and a third photo-resist on the vertical extension place thereof. The fourth light passes through the second photo-resist and filtered for generating a second colored light, passes through the third photo-resist and filtered for generating a third colored light. Thus, the first colored light, second colored light, and third colored light are used to be mixed and collocated for forming full-color light emitting.

  • Publication number: 20060220536
    Abstract: An organic electroluminescent device and method of manufacturing the same are provided. The device comprises a plurality of lower electrodes and at least one insulation layer crossing said lower electrodes. The insulation layer consists of parts of a bottom, a neck, and a top, wherein the action width of the top thereof is smaller than the bottom, which when such formed as a organic light emitting layer, the organic light emitting layer can touch the bottom of the insulation layer to prevent the short circuit from the abnormal contact of the opposite electrode and lower electrode. Further, a separator can be formed between each of the lower electrodes. The separator and the insulation layer can define each pixel position within the organic electroluminescent device. Wherein, the separator can isolate the horizontal light source of the organic light emitting layer to reduce the crosstalk noise for pixels each other.
