An organic light emitting display device according to an embodiment includes: a first anode electrode, a second anode electrode, and a third anode electrode, each anode electrode being spaced apart from each other; a bank disposed on edges of the first to third anode electrodes; a third hole transporting layer disposed on the first to third anode electrodes and the bank, and having a third hole mobility; a first hole transporting layer disposed on the third hole transporting layer and having a first hole mobility higher than the third hole mobility; and a second hole transporting layer disposed next to the first hole transporting layer on the third hole transporting layer and having a second hole mobility higher than the third hole mobility.

Organic light emitting display device

A controller, a data driver circuit, a display device, and a method of driving the same are provided. Color-specific data driving is performed through adaptive overdriving in consideration of differences in response times of color-specific subpixels. Differences in response times of color-specific subpixels due to different thicknesses of color-specific pigment layers are reduced.

Controller, data driver circuit, display device, and method of driving the same

An organic light emitting device and a method for manufacturing the same are provided. The organic light emitting device comprises: a substrate; a first electrode disposed on the substrate; a hole function layer disposed on the first electrode; a first emission layer disposed on the hole function layer; a second emission layer disposed on the first emission layer; an electron function layer disposed on the second emission layer; and a second electrode disposed on the electron function layer, wherein the hole function layer and the first emission layer are melted.
