ORGANIC LIGHT EMITTING DISPLAY DEVICE AND METHOD OF PROVIDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240130190 titled 'ORGANIC LIGHT EMITTING DISPLAY DEVICE AND METHOD OF PROVIDING THE SAME

Simplified Explanation

The abstract describes an organic light-emitting display device with multiple pixel electrodes and light-emitting layers, as well as a thickness compensation layer and a common electrode.

• The device includes a first to a third pixel electrodes and a pixel defining layer on a substrate.
• A first light-emitting layer is on the first pixel electrode, a second light-emitting layer is on the first to third pixel electrodes, and a third light-emitting layer is on the third pixel electrode.
• A thickness compensation layer, containing z-ITO with a zno content of about 50 wt % or more, and about 90 wt % or less, is on the third pixel electrode overlapping the third light-emitting layer.
• A common electrode is disposed on the first to third light-emitting layers.
