Patent ID: 8604687

Claim:
An organic light emitting diode (OLED) display device, comprising: an active array substrate, comprising: a first substrate; and a plurality of thin film transistors disposed on the first substrate so as to form an array; a display substrate, comprising: a second substrate disposed in parallel to the first substrate; a color filter layer disposed on the second substrate and having a plurality of color blocks; a first electrode layer disposed on the color filter layer; an organic material layer disposed on the first electrode layer for emitting white light, wherein the organic material layer comprises a plurality of light-emitting structures electrically insulated from each other; and a second electrode layer disposed on the organic material layer and comprising a plurality of electrode structures electrically insulated from each other; and a plurality of conductive members, wherein each of the conductive members electrically connects to a drain of one corresponding thin film transistor and one corresponding electrode structure; wherein, each of the thin film transistors corresponds to one of the color blocks, one of the light-emitting structures and one of the electrode structures; wherein a work function of each of the conductive members ranges between the work function of the drain of each of the thin film transistors and the work function of each of the electrode structures, and the organic material layer is a multi-layered stack structure.
