Inclined Display Surfaces and Prism Sheets for Border Minimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with multiple modules suffer from visible borders when combined, obstructing users' viewing experience due to frame restrictions around each module.
Innovation Solution
The use of inclined display surfaces and prism sheets to refract display beams, minimizing the border between adjoining modules by directing beams back to a normal line, thereby centralizing images and reducing obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display modules are combined to enlarge display area, then the display area is increased, but visible borders appear between modules obstructing viewing
Solution Approach 1:
The patent introduces a new spatial dimension by tilting the display surface at an angle (e.g., 5-10 degrees) relative to the prism sheet. This dimensional change allows light beams to be directed at oblique angles, enabling the prism sheet to refract border light away from the viewing area and effectively hide borders without reducing display area.
Solution Approach 2:
The patent employs a prism sheet as an intermediary optical element positioned between the display module and the viewer. This intermediary component refracts light beams originating from the tilted display surface, redirecting border light away from the central viewing area and thereby eliminating visible borders while preserving the enlarged display area.
2Adaptability or versatility
If display modules are combined to increase design variety, then design flexibility is improved, but frames around modules create visual separation
Solution Approach 1:
The patent extracts and removes the problematic frame structure from the display module design. By eliminating the frame and tilting the display surface directly, the harmful visual separation caused by frames is removed while preserving the ability to combine multiple modules for diverse design configurations.
Solution Approach 2:
The patent applies dimensional change by tilting the display surface relative to the prism sheet, creating an oblique arrangement that eliminates frame visibility. This allows multiple modules to be combined with enhanced design flexibility while the tilted geometry prevents frame-induced visual separation.
3Object-affected harmful factors
If display surfaces are tilted to minimize borders, then border visibility is reduced, but manufacturing complexity increases
Solution Approach 1:
The patent applies parameter changes by specifying a controlled tilt angle range (5-10 degrees) for the display surface. This parameter optimization achieves effective border minimization through light refraction while keeping the manufacturing complexity manageable, as the moderate angle requires only simple structural adjustments rather than complex mechanisms.
Solution Approach 2:
The patent implements local quality by tilting only the display surface portion adjacent to the prism sheet interface, rather than the entire display module. This localized tilting achieves border minimization at the critical interface area while maintaining simplicity in other regions, thereby reducing overall manufacturing complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively minimizes the border between display modules, enhancing the viewing experience by creating a seamless integrated display surface when multiple modules are combined.
Implementation Method 1
When the inclined display beams reach the first prism sheet, the first prism sheet directs the inclined display beams back to an angle close to the direction of the normal line of the first prism sheet through refraction

AI summary
A display device including a first prism sheet, a second prism sheet disposed side by side with the first prism sheet, a first display module, and a second display module is provided. The first display module is disposed beneath the first prism and has a first display surface. At least a portion of the first display surface close to the second prism sheet is inclined toward the second prism sheet and forms a first angle with respect to the first prism sheet. The second display module is disposed beneath the second prism sheet and has a second display surface. At least a portion of the second display surface closed to the first prism sheet is inclined toward the first prism sheet and forms a first angle with respect to the second prism sheet.
