Modular Backplate Design for Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bar-shaped screens require different sizes of backplates, necessitating multiple sets of molds for production, resulting in high production costs due to the need for various mold sets for different sizes.
Innovation Solution
A backplate design featuring modular components that allow for adjustable accommodation chamber sizes by varying the length of transverse and longitudinal edge portions while maintaining constant width, enabling production with a single set of molds and facilitating adaptation to different-sized optical elements and displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different sizes of backplates are produced using multiple sets of molds, then various sizes of bar-shaped screens can be manufactured, but the production cost increases
Solution Approach 1:
The backplate is divided into a fixed portion and an adjustable edge portion. The edge portion can be adjusted in length to accommodate different screen sizes, while the fixed portion remains constant. This segmentation allows a single mold to produce backplates of various sizes by adjusting only the edge portion length, eliminating the need for multiple mold sets.
Solution Approach 2:
The backplate design incorporates an adjustable edge portion whose length can be dynamically changed to match different screen sizes. This dynamic adjustment capability allows the same backplate structure to adapt to various dimensions without requiring different molds, thereby reducing production costs while maintaining size adaptability.
2Adaptability or versatility
If multiple sets of molds are used for different backplate sizes, then various display sizes can be produced, but the product development cycle lengthens
Solution Approach 1:
By segmenting the backplate into fixed and adjustable portions, the design allows rapid adaptation to different display sizes using the same basic mold structure. This reduces the time required for mold development and product launches for different sizes.
Solution Approach 2:
The fixed portion of the backplate serves multiple functions across different display sizes, while only the edge portion needs adjustment. This universal design approach allows a single mold set to serve multiple product variants, significantly shortening the product development cycle for different sized displays.
3Ease of manufacture
If a fixed-size backplate is used, then mold production is simplified, but adaptability to different screen sizes is reduced
Solution Approach 1:
The backplate is segmented into a fixed portion that maintains manufacturing simplicity and an adjustable edge portion that provides size adaptability. This segmentation allows the majority of the backplate to be produced using a standard mold while only the edge portion requires adjustment for different sizes.
Solution Approach 2:
The adjustable edge portion introduces dynamic adaptability to an otherwise fixed backplate structure. This allows the backplate to accommodate different screen sizes while maintaining the simplicity of mold production for the fixed portion, effectively combining manufacturing ease with size versatility.

AI summary
A backplate and a display panel are disclosed. The backplate includes a first transverse edge portion, a second transverse edge portion disposed opposite to the first transverse edge portion, a first longitudinal edge portion, and a second longitudinal edge portion disposed opposite to the first longitudinal edge portion. The first longitudinal edge portion is connected to the first transverse edge portion and the second transverse edge portion, the second longitudinal edge portion is connected to the first transverse edge portion and the second transverse edge portion, and an accommodation chamber is defined by the first transverse edge portion, the second transverse edge portion, the first longitudinal edge portion, and the second longitudinal edge portion.
