Method for fabricating flexible substrate LCD (liquid crystal display) and flexible substrate LCD

Abstract

The invention discloses a method for fabricating a flexible substrate LCD (liquid crystal display) and the flexible substrate LCD. The fabricating method comprises the following steps of an alignment film fabricating step, a spacer printing step of printing colloidal particles on an upper flexible substrate or a lower flexible substrate, a frame sealing glue printing step of printing frame sealing glue with a predetermined shape on the upper flexible substrate or the lower flexible substrate and reversing a crystal pouring port, a substrate cladding and curing step, and a crystal pouring and sealing step, wherein each colloidal particle at least includes one globular spacer. The globular spacer and the flexible substrate surface are printed on the colloidal particles, and the upper and the lower flexible substrates are fixed together with the frame sealing glue when cladding the plate, so that the globular spacer is located in the colloidal particle and firmly connected with the upper and the lower flexible substrates, even when the liquid crystal rapidly diffuses, the phenomenon that the globular spacer is washed away due to the inefficient adhesive force can be avoided, and the problem of the irregular thickness of the LCD display screen is solved.

Description

technical field

[0001] The invention relates to a manufacturing method of a flexible substrate LCD and the flexible substrate LCD. Background technique

[0002] Existing LCDs generally include an upper substrate 100 and a lower substrate 200. The upper substrate 100 and the lower substrate 200 are fixedly connected by a sealant 300. In order to ensure a certain thickness of the box, a spacer is provided between the lower substrate 100 and the lower substrate 200. The spacer 400 is filled with a liquid crystal material 500 in the remaining space after removing the space occupied by the spacer 400 (see image 3 ).

[0003] The common practice of this LCD is to spray the spacer 400 (mostly spherical spacers) evenly on the surface of the substrate on the surface of the upper substrate 100 or the lower substrate 200 by spraying, On one side of the surface, use the printing method to print the sealant 300, reserve the opening for the crystal filling, and attach the side of the tw...
