Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Producing liquid crystal panels in various irregular shapes requires specialized production processes and components, leading to high production costs and inefficiencies.
Innovation Solution
A method involving a grinding process to shape common liquid crystal panels into irregular forms and a sealing process using a sealing resin to seal the edges, allowing for the efficient production of liquid crystal panels with non-rectangular outlines by removing and re-sealing sections of the sealing member, and optionally attaching a moisture barrier for added protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If specialized production processes and components are prepared for each irregular shape of liquid crystal panel, then various irregular shapes can be produced, but production costs increase significantly
Solution Approach 1:
The patent applies universality by using a common liquid crystal panel as a base for producing multiple different irregular shapes. Instead of creating specialized production lines for each shape, the invention uses one standardized panel that can be processed into various shapes through grinding and selective sealing member removal, making the production system multi-functional and cost-effective
Solution Approach 2:
The patent changes the shape parameter of the liquid crystal panel through a grinding process. By controlling the grinding depth and pattern on the front surface, different irregular shapes can be achieved from the same common panel without changing the underlying structure or requiring specialized components for each shape
2Adaptability or versatility
If existing production facilities are converted to produce irregular shaped panels, then specialized production is enabled, but production processes and components must be completely reprepared
Solution Approach 1:
The patent applies preliminary action by pre-forming a common liquid crystal panel with a rectangular shape and complete sealing members before any shape modification. This preliminary standardized panel serves as a universal starting point that simplifies subsequent processing, as the irregular shapes are created by removing material and selectively removing sealing members rather than building complex structures from scratch
Solution Approach 2:
The patent applies the extraction principle by selectively removing sections of the sealing member after grinding the panel into the desired irregular shape. This allows the sealing structure to adapt to the new shape without requiring complete redesign of the sealing system, extracting only the unnecessary portions while retaining the functional sealing capability
3Shape
If sections of the sealing member are removed to create irregular shapes, then non-rectangular outlines are achieved, but edge sealing must be redone to prevent liquid crystal leakage
Solution Approach 1:
The patent applies local quality by differentiating the treatment of the sealing member in different regions. Sections of the sealing member corresponding to removed panel areas are selectively removed, while sections in retained areas are preserved. The exposed edges are then locally re-sealed with fresh sealing resin, creating a heterogeneous sealing structure that adapts to the irregular shape while maintaining reliability
Solution Approach 2:
The patent applies discarding and recovering by removing the portions of the sealing member that are no longer needed after shape modification, and then recovering sealing functionality by applying new sealing resin to the exposed edges. This ensures that only the necessary sealing portions are retained while new sealing is applied where needed

AI summary
A method of producing a liquid crystal panel includes a grinding process and a sealing process. The grinding process includes grinding at least one common liquid crystal panel including a liquid crystal layer, a pair of boards that sandwich the liquid crystal layer, and a frame-shaped sealing member sandwiched between the boards along the non-rectangular outline to remove a section of the sealing member and to leave a rest of the sealing member. The grinding process further includes forming a sealing member removed processed edge section of the common liquid crystal panel. The sealing member removed processed edge section includes edges of the boards corresponding to the section of the sealing member removed from the common liquid crystal panel. The sealing process includes applying a sealing resin to the sealing member removed processed edge section to fill a space between the edges of the board.
