A picture element for an electro-luminescent display comprises a substrate, a first intermediate structure disposed above a first area of the substrate, at least one first color type electro-luminescent device disposed above the first intermediate structure, a second intermediate structure disposed above a second area of the substrate, and at least one second color type electro-luminescent device disposed above the second intermediate structure. The second intermediate structure is different from the first intermediate structure.

Methods of making combinational structures for electro-luminescent displays

Combinational structures for electro-luminescent displays

An OLED including an anode layer, a first mixing layer over the anode layer, a mixing layer on the first mixing layer, a second mixing layer on the mixing layer, and a cathode layer over the second mixing layer is provided. The mixing layer is a mixture of an organic light emitting material, a hole and an electron transport material, and a volume ratio of the hole transport material to the electron transport material thereof is X %. The first and second mixing layers are both mixtures of the hole and electron transport materials. A volume ratio of the hole transport material to electron transport material in the first mixing layer decreases gradually from 99% to X % starting from the surface adhered to the anode layer, and that of the second mixing layer increases gradually from X % to 99% starting from the surface adhered to the mixing layer.

Organic light emitting device with increased service life

An organic electroluminescent device, having a cathode, an indium-tin-oxide anode, an emitting layer, a hole transport layer, an electron transport layer, a hole injecting layer and a intermediate layer. The emitting layer is located between the cathode and the indium-tin-oxide anode. The hole transport layer is located between the emitting layer and the indium-tin-oxide anode, the electron transport layer is located between the emitting layer and the cathode, the hole injecting layer is located between the hole transport layer and the indium-tin-oxide anode, and the intermediate layer is located between the hole injecting layer and the hole transport layer.
