Display Device Board Stacking for Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices require new design and manufacturing of internal parts when changing screen sizes, leading to increased costs due to the lack of sharing of internal components across different screen sizes.
Innovation Solution
A display device configuration that includes a display panel, board attachment components, and a main board that stores multiple display programs, allowing sharing of components and minimizing cost increases by stacking boards and attaching them in a specific order, with a control block that uses the same interface for various screen sizes and a signal transmission component that bypasses the power supply board to reduce noise and simplify manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If internal parts are newly designed for each screen size, then display device performance can be optimized for each size, but development cost and manufacturing complexity increase
Solution Approach 1:
The patent applies universality by designing a standardized mounting structure with universal mounting holes and attachment components that can accommodate multiple display panel sizes. The housing includes a standardized board mounting structure that allows the same internal parts to be used across different screen sizes, eliminating the need to redesign internal components for each display variant.
Solution Approach 2:
The patent segments the display device into modular components: a standardized control unit housing with fixed internal mounting structure, and variable display panels that can be attached to this standardized base. This segmentation allows the internal parts to remain constant while only the display panel changes, reducing overall system complexity.
2Ease of manufacture
If external panels are shared across products, then manufacturing cost decreases, but internal parts still require separate design and management
Solution Approach 1:
The patent merges the control unit housing design to incorporate a standardized board mounting structure that serves all display panel sizes. By combining the housing design with universal mounting features, the same internal parts can be used across different products, extending cost savings from panel sharing to internal component sharing as well.
3Adaptability or versatility
If board attachment components are redesigned for each screen size, then board compatibility improves, but production time and cost increase
Solution Approach 1:
The board attachment components are designed with universal mounting holes and attachment mechanisms that can secure multiple board sizes and types. The standardized mounting structure allows the same attachment components to be used across different display panel configurations, maintaining board compatibility while enabling high-volume standardized production.

AI summary
A display device is provided which suppresses cost increases attributable to design changes and so forth for things disposed on the inside of a product when a plurality of products of different screen size are developed, or when the screen size is changed. A display device 5 includes a display panel 11, a first board attachment component 13, a display panel board 18, a second board attachment component 21, a main board 22, a third board attachment component 23, and a power supply board 24. The main board 22 stores a plurality of display programs that produce an image to be displayed on the display panel 11, according to the screen size of the display panel 11. The first board attachment component 13, the display panel board 18, the second board attachment component 21, the main board 22, the third board attachment component 23, and the power supply board 24 are disposed in this order, starting from the display panel 11 side, on the rear side of the display panel 11.
