Manufacturing method of flexible AMOLED (active matrix/organic light emitting diode) display screen and conductive adhesive film layer

Abstract

The invention provides a manufacturing method of a flexible AMOLED (active matrix / organic light emitting diode) display screen and a conductive adhesive film layer. The flexible AMOLED display screen is provided with a flexible substrate (21), a plurality of bonding terminals (22), a conductive adhesive film layer (23) and an IC (integrated circuit) chip by layers from bottom to top; the conductive adhesive film layer (23) comprises a plurality of conductive thin films (231) and a plurality of insulation thin films (232), which are sequentially and alternatively staggered in the extending direction of the IC chip (24); the conductive thin films (231) are used for replacing the conductive particles which are dispersed in the existing anisotropic conductive adhesive thin films and only can be broken by larger stress to conduct the IC chip (24) and the bonding terminals (22). The manufacturing method can solve the problems of cracks of the flexible substrate and failure to conduct the IC chip and the bonding terminal due to the unbroken conductive particles in the bonding process of the prior art.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for manufacturing a flexible AMOLED display screen and a conductive adhesive film layer. Background technique [0002] In the field of display technology, organic light emitting diode display (Organic Light Emitting Diode, OLED) has thin, light, wide viewing angle, active light emission, continuously adjustable light color, low cost, fast response speed, low energy consumption, low driving voltage, Wide operating temperature range, simple production process, high luminous efficiency and flexible display, etc., are known as "dream display". According to the driving method, OLED screens can be divided into two categories: Passive Matrix (PM) OLED and Active Matrix (AM) OLED, namely direct addressing and thin film transistor (Thin Film Transistor, TFT) matrix. Two classes of addressing. [0003] In the production process of flexible (Flexible) AMOLED displays, Anisotropi...
