US 2024/0206291 A1 · ORGANIC LIGHT-EMITTING DIODE DISPLAY DEVICE

Abstract

An organic light-emitting diode display device can include a substrate including sub-pixels associated with one pixel, each sub-pixel having an emission area and a non-emission area; first conductive lines and a second conductive line over the substrate, wherein the second conductive line crosses over the first conductive lines to define the sub-pixels; a circuit portion in the non-emission area of each sub-pixel, and including a thin film transistor in each sub-pixel; an overcoat layer over the thin film transistors and including micro lenses in the emission area of each sub-pixel; and a light-emitting diode in the emission area of each sub-pixel over the overcoat layer, and connected to the corresponding thin film transistor. For a first sub-pixel among the sub-pixels, the overcoat layer can have a depressed pattern corresponding to the non-emission area of the first sub-pixel and overlapping one of the first conductive lines.
