Abstract

The invention provides an array substrate and a manufacturing method thereof, and an organic light emitting display. The array substrate comprises a substrate, organic light emitting devices formed on the substrate, pixel definition layers arranged between the adjacent organic light emitting devices, and supporting columns formed on the pixel definition layers, wherein vertical sections of the supporting columns are arc surfaces. The array substrate is advantaged in that the vertical sections of the supporting columns are the arc surfaces, gradual buffering for external impact force can be realized, so anti-impact capacity of a display screen can be improved, and shedding or position offset phenomena of the supporting columns can be avoided.

Description

technical field [0001] The invention relates to the field of flat panel display technology, in particular to an array substrate, a manufacturing method thereof, and an organic light emitting display. Background technique [0002] Organic light-emitting display (English full name Organic Lighting Emitting Display, referred to as OLED) is an active light-emitting device. Compared with thin film transistor liquid crystal display (English full name Thin Film Transistorliquid crystal display, referred to as TFT-LCD), OLED has high contrast and wide viewing angle. , low power consumption, thinner volume and other advantages, it is one of the most concerned technologies in flat panel display technology. [0003] An organic light-emitting display usually includes an array substrate and a packaging cover that are arranged opposite to each other. There is a gap of a certain thickness between the array substrate and the packaging cover. In order to avoid deformation of the array substr...
