Liquid Crystal Panel Cavity Design for Frameless Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid crystal display panels have a wide frame due to the arrangement of sealants, which reduces the screen-to-body ratio and does not meet consumer demands for a more aesthetically pleasing appearance.
Innovation Solution
A liquid crystal panel design featuring a substrate, electrode layer, insulating layer with a cavity, and alignment layers, where the liquid crystal layer is located within the cavity, eliminating the need for a sealant and thus reducing the frame width, achieved through a manufacturing method involving the formation of an electrode layer, sacrificial layer, insulating material layer, and alignment of spontaneous alignment liquid crystals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealant is used to connect the upper substrate and the lower substrate, then the structural integrity and reliability of the liquid crystal panel are improved, but the frame width increases, reducing the screen-to-body ratio
Solution Approach 1:
The invention extracts and eliminates the sealant from the liquid crystal panel structure. By using a cavity within the insulating layer to contain the liquid crystal, the sealant is no longer needed to surround the liquid crystal, thereby removing the source of the wide frame problem while maintaining structural integrity through the cavity-contained design
Solution Approach 2:
The invention applies the nesting principle by placing the liquid crystal layer inside a cavity formed within the insulating layer. This nested structure allows the liquid crystal to be contained without requiring an external sealant, integrating the containment function into the insulating layer itself and eliminating the need for additional sealing components that would increase frame width
2Reliability
If a sealant is arranged to surround the liquid crystal, then the liquid crystal is properly contained and maintained, but the frame becomes excessively wide, reducing aesthetic appeal and screen-to-body ratio
Solution Approach 1:
The invention merges the containment function with the insulating layer by forming a cavity within it. The insulating layer simultaneously provides electrical insulation and mechanical containment for the liquid crystal, eliminating the need for a separate sealant structure and thereby reducing frame width while maintaining proper liquid crystal containment
Solution Approach 2:
The invention transitions from a two-dimensional sealant arrangement (surrounding the liquid crystal in the plane) to a three-dimensional cavity structure (containing the liquid crystal within a volume). This dimensional change allows containment without requiring the sealant to extend to the edges, thus reducing frame width while maintaining containment effectiveness

Function Achieved in This Case
The design allows for a narrower or frameless liquid crystal panel, enhancing the screen-to-body ratio and aesthetic appeal by eliminating the need for a sealant, while maintaining the advantages of liquid crystal display panels such as small size and low radiation.
Implementation Method 1
filling a spontaneous alignment liquid crystal in the cavity; and aligning the spontaneous alignment liquid crystal to form a first alignment layer, a liquid crystal layer, and a second alignment layer that are located in the cavity
