Embodiment 1

[0042] In order to solve the above problems, the present invention provides a method for manufacturing a flexible substrate, which includes the following steps:

[0043] Step A1, forming a first flexible layer 100 on the first hard substrate.

[0044] The first flexible layer 100 is divided into several first panel areas 110, each of which includes a cutting area 112 and a non-cutting area 113 separated by a first cutting line 111; the non-cutting area 113 It includes a first display area 1131 and a first sealing area 1132 surrounding the first display area 1131 .

[0045] The material of the hard substrate is preferably but not limited to glass, such as alkali-free glass. The material of the flexible layer includes organic polymer materials, preferably but not limited to PI, TAC; the usual thickness is about 50-100 μm. In order to realize the separation of flexible structures, it is often necessary to use a glass substrate as a support for the flexible substrate. The glass...

Embodiment 2

[0054] The present invention also provides a method for manufacturing a flexible display panel, which includes the following steps:

[0055] Step B1, providing the flexible substrate of Example 1.

[0056] Step B2, forming a color filter assembly on each non-cutting area 113 of the flexible substrate in step B1 to obtain a flexible color filter substrate.

[0057] Each of the non-cutting areas 113 includes a first display area 1131 and a first sealing area 1132 surrounding the first display area 1131 . Forming the color filter assembly on the non-cutting area 113 specifically includes the following steps:

[0058] In the non-cutting area 113, a black matrix is ​​formed on the first flexible layer on which the cutting compensation layer has been formed;

[0059] In the first display area 1131 , a color filter layer is formed on the first flexible layer on which the black matrix has been formed.

[0060] Preferably, it also includes:

[0061] In the non-cutting area 113, a t...

Embodiment 3

[0075] The present invention also provides a method for manufacturing a flexible display panel, which includes the following steps:

[0076] Step C1, providing the flexible substrate of Example 1;

[0077] Step C2, forming a display device in the first display area 1131 on each non-cutting area 113 of the flexible substrate in step C1, to obtain a flexible array substrate.

[0078] It should be noted that the display device includes an electronic component layer and a display material layer; wherein the electronic component layer includes thin film transistors, electrophoretic display components, organic light emitting diode display components, scanning lines, data lines, display electrodes, etc., The production process is such as coating, deposition, etching, high temperature treatment, etc.; the display material layer can be various films with realistic characteristics such as liquid crystal layer, organic light-emitting layer, electrochromic layer, electronic ink layer, cho...

Abstract

The invention discloses a manufacture method of a flexible substrate and a manufacture method of a flexible display panel. The method comprises the following steps: step A1, a first flexible layer is formed on a first hard substrate, the first hard substrate is divided into a plurality of first panel areas, and each first panel area comprises a cutting area and a non-cutting area which are divided by a first cutting line; step A2, a cutting compensation layer is formed in the first flexible layer, and the first flexible layer is divided into a plurality of first areas and a plurality of second areas, wherein the first cutting line is positioned in the first area; step A3, laser cutting is performed along the first cutting line; after cutting, the cutting compensation layer in the first area is removed through exposure and development, so that the flexible substrate is obtained. The cutting compensation layer is manufactured on the surface of the flexible substrate, the cutting compensation layer subjected to bulging deformation on the two sides of the first cutting line is removed through laser cutting and exposure and development, quantity production of flexible displays is realized, and the production yield is improved.

Description

technical field [0001] The present invention relates to the technical field of flexible display, in particular to a method for manufacturing a flexible substrate and a method for manufacturing a flexible display panel. Background technique [0002] A flexible display panel, also known as a rollable display, is a display device that can be bent and deformed by making a visible flexible panel with flexible materials. Flexible display panels are one of the hottest trends in display technology. Although it has not been popularized in the market yet, it is foreseeable that scroll-type PDAs or e-book readers are no longer far away, and large-format wall-mounted flexible display panels will soon become a reality. For example, all visual materials, including various books, newspapers, magazines and video files, can be presented through this display and can be viewed anytime and anywhere. Flexible electronic displays have incomparable advantages. Like newspapers, they can be unfold...
