Transparent Plates With Deflection Portions For Seamless Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Array-type display apparatuses face challenges in reducing the visibility of non-display areas between devices, leading to discontinuities in images and lowered image quality due to frame structures and electrode requirements.
Innovation Solution
The use of transparent plates with light exit-side and corner deflection portions that inwardly bend light, and light entrance-side deflection portions that outwardly bend light, to minimize the visibility of non-display areas and enhance image continuity by strategically deflecting light to create a seamless image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a frame structure or holding member is used to support the display panel, then the structural stability is improved, but the non-display area increases and image continuity deteriorates
Solution Approach 1:
The patent removes the traditional frame structure and holding member that created non-display areas. Instead, the display panel is directly supported by mounting it to the rear surface of the rear projection screen, extracting the supporting function from a separate frame structure and integrating it into the screen assembly, thereby eliminating the non-display areas while maintaining structural stability
Solution Approach 2:
The patent merges the support function with the rear projection screen itself. The display panel is mounted directly to the rear surface of the screen, combining the screening function and support function into a single integrated structure, eliminating the need for separate frame structures and holding members that would create non-display areas
2Ease of operation
If electrode wiring is provided in the peripheral portion of the display device, then the display function is improved, but the non-display area increases and image continuity deteriorates
Solution Approach 1:
The patent moves the electrode wiring from the peripheral area (2D plane) to the rear surface dimension. By providing electrodes on the rear surface of the display panel rather than along the edges, the wiring is positioned in a different spatial dimension that does not create non-display areas in the front viewing area, thus maintaining image continuity while enabling display function
3Area of stationary object
If a narrow holding member is used to reduce the non-display area, then the non-display area is reduced, but the electrode still requires a peripheral non-display area of a few millimeters
Solution Approach 1:
The patent relocates electrode positioning from the peripheral edge (2D plane constraint) to the rear surface dimension. This dimensional change allows electrodes to be positioned without requiring peripheral non-display areas, achieving both minimal non-display area and proper electrode functionality without compromising manufacturing precision
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
Significantly reduces the visibility of non-display areas, resulting in improved image continuity and quality by ensuring that the entire display area appears as a single, continuous image.
Implementation Method 1
a light exit-side deflection portion for inwardly bending a traveling direction of at least part of light that has exited the display section and passed through the transparent plate
Implementation Method 2
corner deflection portions, provided at the corners of the viewer-side surface, for inwardly bending a traveling direction of at least part of light that has exited the corresponding display section and passed through the transparent plate
Implementation Method 3
light entrance-side deflection portions that outwardly bend light
