Problems solved by technology

[0005] like figure 1 As shown, the existing flexible OLED display device assembly method is to first bond the OLED body 100 and several chip-on-chip films 200, and then bond the flexible circuit board 300. Defective, the most costly but relatively fragile OLED body 100 will be scrapped during heavy work, resulting in waste of cost

Abstract

The present invention provides a flexible OLED display device assembling method. The method comprises the steps of firstly, connecting a crystal covering film (2) to a flexible circuit board (1) to form a peripheral circuit (12), screening out the qualified peripheral circuit (12) through examination, and finally connecting the qualified peripheral circuit (12) to an OLED body (3). In this way, the scrapping risk of the OLED body (3) during the module stage is reduced, and the assembly yield is improved. The production cost is saved.

Description

technical field [0001] The invention relates to the technical field of OLED display device manufacturing process, in particular to a method for assembling a flexible OLED display device. Background technique [0002] At present, the development of Liquid Crystal Display (LCD) has entered a mature stage, and Organic Light-Emitting Diode display device (Organic Light-Emitting Display, OLED) has become a new growth point of the display industry in the future. OLED has self-illumination (no need for backlight), low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide operating temperature range, and can realize flexible display and large-area full-color display, etc. Many advantages are called "dream display" by the industry. [0003] According to the driving mode, OLEDs can be divided into two types: passive driving and active driving, that is, direct addressing and thin film transistor (Thin Film Transis...
