Abstract
A projector employing multiple organic electroluminescence (OEL) image panels, in which each image panel is made with multiple light-emitting OEL components. Each light-emitting OEL component represents one image element. The OEL component is capable of emitting individual prime colors, red (R), green (G) or blue (B), or producing white light which is then made to passes through color filters to produce RGB colors. The new structure for the projector provides the features of downsized dimensions, luminous efficiency and light-focusing capability.
