Concave Groove Support Frame for Edge Pixel Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LCD splicing technologies face issues where the support frame's width limit blocks edge pixels in the display region, resulting in a smaller displayed image size and visual seams between adjacent panels, degrading user experience with potential rainbow patterns.
Innovation Solution
A support frame design featuring a concave groove with a light-transmitting structure that includes an engaging and light-transmitting portion, allowing light to reach edge pixels and preventing the light-transmitting portion from being stripped, ensuring proper display and reduced visual seams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the support frame width is reduced to enable 1 mm level splicing, then the splicing precision is improved, but the support frame cannot provide sufficient support to the display panel edge region
Solution Approach 1:
The support frame is segmented into two functional zones: a first support surface region providing mechanical support and a second light-transmitting region allowing light passage. This segmentation enables the frame to simultaneously achieve precise splicing (by reducing overall width) while maintaining support capability through the structured first support surface that extends to edge pixels.
Solution Approach 2:
Different regions of the support frame are assigned different properties: the first support surface has high structural integrity for support, while the second region has light-transmitting properties. This local differentiation allows the frame to provide targeted support to edge pixels without blocking light, resolving the contradiction between precision and strength.
2Strength
If the support frame blocks light to maintain structural integrity, then the strength is improved, but the edge pixels cannot display normally causing visual seams
Solution Approach 1:
The support frame is divided into a first support surface for structural integrity and a second light-transmitting region for light passage. This segmentation allows the frame to maintain strength where needed while transmitting light to edge pixels, eliminating visual seams without compromising structural integrity.
Solution Approach 2:
The first support surface acts as an intermediary structure that provides mechanical support while allowing light to pass through to the second region. This intermediary structure resolves the conflict between needing structural integrity and requiring light transmission for normal edge pixel display.
3Strength
If the support frame is made wider to support edge pixels, then the support capability is improved, but the splicing gap increases beyond 1 mm level
Solution Approach 1:
The support frame is segmented into a first support surface region and a second light-transmitting region, allowing the overall frame width to remain narrow (1 mm level for precise splicing) while the first support surface provides adequate support capability to edge pixels through its optimized structure.
Solution Approach 2:
The first support surface is designed with specific local properties to provide maximum support capability within the constrained width. This local optimization enables the frame to support edge pixels effectively without increasing the overall width, thereby maintaining 1 mm level splicing precision.
4Manufacturing precision
If the light-transmitting structure is made thinner to reduce frame width, then the splicing precision is improved, but the light-transmitting portion may be stripped
Solution Approach 1:
The light-transmitting structure is segmented into an engaging portion for attachment and a light-transmitting portion for optical function. This segmentation allows the engaging portion to be sufficiently thick for reliable attachment while the light-transmitting portion remains thin for precise splicing, resolving the contradiction between precision and reliability.
Solution Approach 2:
The engaging portion acts as an intermediary between the light-transmitting portion and the support frame body. It provides a robust attachment interface that prevents stripping while allowing the light-transmitting portion to remain thin for precise splicing, thus maintaining both reliability and precision.
