Organic light-emitting display apparatus

摘要

A method of manufacturing a polysilicon (poly-Si) layer, a method of manufacturing an organic light-emitting display apparatus using the method, and an organic light-emitting display apparatus manufactured by using the method. The method includes forming an amorphous silicon (a-Si) layer on a substrate having first and second areas, thermally treating the a-Si layer to partially crystallize the a-Si layer into a partially crystallized Si layer, removing a thermal oxide layer through a thermal treatment, selectively irradiating the first areas with laser beams to crystallize the partially crystallized Si layer.

主权项

1. An organic light-emitting display apparatus comprising:
a substrate having a first area comprising a poly-Si layer and a second area comprising a partially crystallized Si layer; and a plurality of light-emitting devices on the substrate, wherein: each of the light-emitting devices comprises a thin film transistor (TFT), a light-emitting unit, and a capacitor, aligned in a longitudinal direction, and the light-emitting devices of the plurality of light-emitting devices that are adjacent to each other in the longitudinal direction are arranged such that the TFTs are adjacent to each other and/or the capacitors are adjacent to each other.
