Abstract
An organic light-emitting device includes a substrate, a first electrode layer, a light-emitting layer, and a second electrode arranged in layers. The light-emitting layer includes primary pixels, each of which includes three or more subpixels. One of the subpixels is a white subpixel. The other subpixels includes a basic subpixel which has a light-emitting material necessary to synthesize the white light. The basic subpixels includes an original color zone and a synthesized color zone. The light-emitting material for the synthesized white light corresponding to the synthesized color zone of the basic subpixels and another kind of light-emitting material for the synthesized white light are layered or mixed to form the subpixel with the white light. The brightness and color of the image is enhanced, power consumes less, and the life span of the organic light-emitting device is extended.
