Inverted Coupled Display Units for Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high manufacturing costs of multiscreen display devices due to differences in structure among individual display units, leading to increased production expenses.
Innovation Solution
A coupled display device configuration featuring two liquid crystal display units with inverted positions, where each unit has a frame portion with linear sections that align to maintain display area integrity and reduce displacement, allowing for a common structure that lowers production costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple display devices with different structures are used according to placement position, then display quality and aspect are improved, but manufacturing cost increases
Solution Approach 1:
The patent applies inversion by arranging display devices in inverted positions (first position and second position that is inverted from the first position) while using a common structure. This allows the same display device to be used in multiple orientations, eliminating the need for different structured devices for different placements, thus reducing manufacturing cost while maintaining display quality
Solution Approach 2:
The patent makes the display device universal by designing it to function correctly in both normal and inverted positions. The frame portions and linear sections are configured to maintain proper display area definition regardless of orientation, allowing a single device design to serve multiple placement scenarios, thereby reducing the need for multiple specialized device variants
2Stability of the object's composition
If display devices are arranged in close proximity with depressions and projections, then coupling stability is improved, but structural complexity increases
Solution Approach 1:
The patent uses asymmetric frame portion configurations where the first frame portion has a first linear section and the second frame portion has a third linear section with specific directional orientations. This asymmetric linear section arrangement provides stable coupling between adjacent display devices while maintaining a relatively simple overall structure, avoiding the need for complex depression-projection mechanisms

AI summary
A coupled display device includes a first display unit and a second display unit arranged adjacent to each other and coupled. The first display unit includes a first display portion and a first frame portion including two first linear sections and two second linear sections perpendicular to the first linear sections. The second display unit includes a second display portion and a second frame portion including two third linear sections and two fourth linear sections. The first display unit is set in a first position. The second display unit is set in a second position that is inverted from the first position. The first linear sections and the third linear sections extend in an arrangement direction in which the first display unit and the second display unit are arranged. The second linear sections and the fourth linear sections extend in a direction perpendicular to the arrangement direction.
