Flexible Liquid Crystal Panel Substrate with Pre-Encapsulated Capsules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal display device manufacturing processes are unsuitable for flexible displays due to the use of glass substrates and hot press methods, which lead to increased manufacturing costs and complexity, and the adhesion of polarizing plates can deteriorate optical characteristics.
Innovation Solution
A first substrate sheet with a transparent electrode, a liquid crystal capsule mixed with a binder, and a removable releasing sheet is used, allowing for the encapsulation of liquid crystals on one substrate, simplifying the manufacturing process by eliminating the need for hot press and orientation film formation, and omitting the polarizing plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hot press process is used to assemble substrates, then the liquid crystal display device can be manufactured with glass substrates, but the manufacturing process becomes unsuitable for flexible display devices with plastic film substrates that are sensitive to heat
Solution Approach 1:
The liquid crystal is encapsulated and bonded to the first substrate in advance before the final assembly with the second substrate. This preliminary action eliminates the need for hot press processes during final assembly, making the device suitable for flexible plastic substrates while simplifying the manufacturing process.
Solution Approach 2:
The device is divided into separate modules: a first substrate with pre-encapsulated liquid crystal, and a second substrate. This segmentation allows each component to be manufactured independently using appropriate processes, with the first substrate being heat-sensitive and the second substrate being assembled later without requiring hot press.
2Productivity
If conventional manufacturing processes are used with multiple steps for substrate assembly and liquid crystal injection, then the display device can be manufactured, but the manufacturing process becomes long and complicated, reducing process yield ratio
Solution Approach 1:
The liquid crystal encapsulation and bonding processes are merged into a single integrated step on the first substrate. This combines multiple conventional steps (liquid crystal injection, sealing, bonding) into one process, significantly reducing manufacturing complexity and improving productivity.
Solution Approach 2:
The liquid crystal encapsulation is performed as a preliminary action on the first substrate before final assembly. This preliminary encapsulation step eliminates the need for subsequent complex sealing and bonding operations, reducing the total number of manufacturing steps and improving yield ratio.
3Reliability
If a polarizing plate is used in the liquid crystal display device, then the display can function, but errors in adhesion direction cause deterioration in optical characteristics and the adhesion process makes manufacturing complicated
Solution Approach 1:
The polarizing plate is completely removed from the device structure. Instead, the liquid crystal capsule itself provides the necessary optical functions, eliminating the adhesion complexity and potential defects associated with polarizing plate installation while maintaining optical characteristics.

AI summary
The present invention relates to a liquid crystal panel having the first substrate sheet. The object of the present invention can be accomplished by a liquid crystal capsule which is mixed with a binder and printed on one surface of the first substrate on which the transparent electrode is formed; a transparent adhesive applied to entirely cover the liquid crystal capsule and the binder printed on the first substrate; and a releasing sheet which is attached to entirely cover the transparent adhesive applied on the first substrate.
