Prism Optical Element Between Display Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frames of multiple screens interfere with the viewing quality when spliced together, affecting the immersive and vivid visual experience of both flat and curved screens.
Innovation Solution
A display apparatus with a prism structure optical element is used between adjacent screens, covering their side edges and portions of the display areas, which refracts and reflects light to minimize the visibility of frames, improving display quality and preventing damage to the prism pillars.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple screens are spliced together to form a multi-screen display, then the display area and information processing capability are improved, but the frames between screens become visible and affect viewing quality
Solution Approach 1:
A prism structure optical element is introduced as an intermediary component between adjacent display screens. This optical element refracts and reflects light to redirect the image from one screen through the prism structure to the viewer's eye, effectively masking the frame between screens and eliminating the visual disruption caused by frame visibility.
Solution Approach 2:
The patent utilizes optical properties including refraction and reflection to manipulate light paths. By changing the direction of light through the prism structure, the visible boundary between screens is eliminated, creating a seamless visual experience where frames become imperceptible to the viewer.
2Object-affected harmful factors
If a prism structure optical element is placed between adjacent screens to mask frames, then frame visibility is reduced, but the prism structure may be damaged or scratched by viewer contact
Solution Approach 1:
The prism structure optical element is positioned in a spatial dimension between the display screens and the viewer, creating a protective barrier. This three-dimensional placement allows the optical element to serve dual functions: refracting light to mask frames while simultaneously protecting the underlying display components from direct viewer contact and potential damage.
Solution Approach 2:
The patent positions the optical element as a protective layer before viewer contact can reach vulnerable components. This preemptive placement acts as a cushioning barrier that prevents direct contact between the viewer and the display screens or internal components, protecting against scratches and damage before they can occur.
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
The solution effectively reduces the perception of frames between screens, enhancing the display quality by directing light to the viewer and preventing damage to the prism structure, thus providing a seamless viewing experience without compromising the visual quality.
Implementation Method 1
The prism structure optical element can direct a light emitted from a portion of the display area that is covered by the prism structure optical element to a viewer's eye
Implementation Method 2
Each of the first prism pillars has a first total reflecting surface and a first refracting surface, and the first total reflecting surface is located between the first refracting surface and the second region
