Abstract

The invention provides a method for manufacturing an OLED display panel. The method comprises the steps of: providing a support base; forming a substrate layer on the support base; forming a buffer layer on the substrate layer; forming a flexible polymer layer on the buffer layer; forming an OLED array layer on the flexible polymer layer; and using a laser to heat the support base to decompose the buffer layer, thereby separating the substrate layer from the flexible polymer layer.

Description

【Technical field】 [0001] The invention relates to the field of organic light emitting diode panels, in particular to a method for manufacturing an OLED display panel. 【Background technique】 [0002] Among flat panel display technologies, Organic Light-Emitting Diode (OLED) displays have many advantages such as thinness, active light emission, fast response speed, large viewing angle, wide color gamut, high brightness and low power consumption, etc., and have gradually become a new trend. A generation of display technology. [0003] In the manufacturing process of OLED display panels, laser lift-off (laser lift-off, LLO) is the step of separating the glass substrate from the flexible polyimide (PI) layer by using laser, in which the laser will destroy the glass and polyimide. Hydrogen bonding forces between the imide layers to achieve effective separation between the glass and polyimide layers. However, if the energy of the laser is too low, the polyimide layer and the glas...
