Color Resist Layer as Spacer in Narrow Frame Display Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Narrow frame display panels experience display unevenness near the sealant due to compression of spacers, leading to increased design costs.
Innovation Solution
A display panel design featuring a first and second substrate with a sealant and at least one color resist layer in an alternate arrangement between them, where the color resist layer supports the substrates instead of traditional spacers, reducing the need for spacers and thus lowering design costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If spacers are added into the sealant to support substrates, then substrate support is improved, but display unevenness occurs near the sealant due to spacer compression
Solution Approach 1:
The patent removes the spacer element from the sealant structure entirely. Instead of adding spacers to provide support, the invention uses the color resist layer itself to provide the necessary support function, eliminating the source of compression-induced display unevenness while maintaining substrate support capability
Solution Approach 2:
The color resist layer is given multiple functions: it serves both as the color filter layer and as the support structure for the substrates. This multi-functionality eliminates the need for separate spacer elements, thereby solving the display unevenness problem while maintaining structural support
2Strength
If spacers are added into the sealant to support substrates, then substrate support is improved, but design cost increases
Solution Approach 1:
The patent eliminates the spacer component from the design, reducing the number of parts and simplifying the manufacturing process. This reduction in components directly lowers design and production costs while maintaining the necessary substrate support function through the color resist layer
Solution Approach 2:
The invention merges the color resist layer and support structure into a single integrated component. By combining the color filter function and support function into one element, the patent reduces the total component count and simplifies the overall design, thereby reducing design costs

AI summary
A display panel includes a first substrate and a second substrate disposed separately; a sealant disposed between the first substrate and the second substrate; and at least one color resist layer disposed between the first substrate and the second substrate; wherein, the at least one color resist layer and the sealant are disposed in an alternate arrangement, and are disposed between the first substrate and the second substrate in order to support the first substrate and the second substrate. A display device is also disclosed. Through replacing the spacers in the sealant with the color resist layer to support the first substrate and the second substrate, a display uneven phenomenon near the sealant of a narrow frame display panel is solved. In addition, because the color resist layer replaces the spacer, the cost of the spacer is saved so as to reduce the design cost.
