Display panel and manufacturing method thereof

Abstract

The invention provides a manufacturing method of a display panel. The manufacturing method comprises steps as follows: multiple patterned first flexible substrates are formed on a first rigid substrate, and multiple patterned second flexible substrates are formed on a second rigid substrate; an array process is completed on each first flexible substrate to form multiple array areas, and a color film process is completed on each second flexible substrate to form multiple color film areas; the array areas and the color film areas are in one-to-one correspondence to form multiple liquid crystal boxes; the liquid crystal boxes are cut and separated along boundaries of the first flexible substrates and the second flexible substrates; the first rigid substrate and the first flexible substrates of the liquid crystal boxes are lifted off, and the second rigid substrate and the second flexible substrates of the liquid crystal boxes are lifted off. The flexible substrates matched with the shapesof the liquid crystal boxes independently are formed in advance, during cutting, the liquid crystal boxes are cut and separated along the boundaries of the flexible substrates, and accordingly, the phenomenon of incomplete cutting of the morphology of cutting edges of the flexible substrates can be prevented.

Description

technical field [0001] The invention belongs to the technical field of display panel manufacturing, and in particular relates to a display panel and a manufacturing method thereof, in particular to a flexible display panel and a manufacturing method thereof. Background technique [0002] With the gradual rise of wearable application devices such as smart glasses and smart watches, the demand for flexible display devices in the display industry is also increasing. Organic light emitting diode (Organic Light Emitting Display, OLED) display has the characteristics of self-illumination without backlight, thin thickness, wide viewing angle, fast response speed, etc., so it has the natural advantages of flexible display. However, the current OLED industry still has a high technical threshold, difficult manufacturing process, low yield, high cost, and high price. These difficulties hinder the wide application of OLED. [0003] Liquid Crystal Display (LCD) has a relatively long dev...

Problems solved by technology

[0005] Usually, in the basic manufacturing process of flexible liquid crystal display devices, after the cell forming process is completed, each liquid crystal cell needs to be cut separately, and the glass substrates on the CF (color film) side and the Array (array) side are peeled off, and then The process of polarizing the polarizer, bonding the chip and the flexible circuit board (IC&FPC bonding), and assembling the backlight module, among which the cutting process mainly adopts the cutter wheel cutting process in the traditional liquid crystal display device manufacturing process, and the cutter wheel needs to be on the glass substrate. However, the PI substrate has a certain degree of flexibility and the PI substrate and the glass substrate have limited adhesion. Therefore, the cutting edge of the PI substrate is likely to be unclean due to the cutting edge of the PI substrate, thus affecting the liquid crystal device. Performance has a fatal impact
