Title:
ORGANIC LIGHT EMITTING DISPLAY DEVICE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/028020
Kind Code:
A1
Abstract:
Provided are an organic light emitting display device and a manufacturing method therefor, and the organic light emitting display device comprising: a substrate layer (101), a first electrode layer (102), a light emitting layer (103), and a second electrode layer (104) which are sequentially laminated; the organic light emitting display device comprises a plurality of main pixels in a display region, each main pixel being defined to have at least three sub-pixels, wherein one sub-pixel is a white light sub-pixel, and at least one of the remaining sub-pixels is a basic sub-pixel comprising a light emitting material of a color necessary for synthesizing a white light; the basic sub-pixel comprises a natural color region and a combined light region, and in the combined light region, the corresponding light emitting material of a color necessary for synthesizing a white light is laminated or mixed with another light emitting material of a color necessary for synthesizing a white light, so as to form white light basic sub-pixels. The provided organic light emitting display device may improve the brightness and color saturation of a picture, conserve energy, and extend the service life of the organic light emitting display device.
