Abstract
A method for manufacturing an OLED display panel is provided. The method includes steps of providing an array substrate; forming an OLED function layer including a first common layer, an organic light-emitting layer, and a second common layer on the array substrate; forming a first opening at a location near to the organic light-emitting layer using a first laser; forming a thin-film encapsulation layer on the OLED function layer; forming a second opening at a location corresponding to the first opening using a dry etching technique, the second opening passing through an inorganic layer of the thin-film encapsulation layer and at least one inorganic layer of the array substrate, and being connected to the first opening; and forming a perforated hole in the substrate at a location corresponding to the second opening using a second laser, thereby producing a through-hole in the OLED display panel.
