Overlay Panel Light Guides Conceal Display Bezel Artifacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display systems suffer from visually unpleasing bezel artifacts and inconsistent viewing experiences due to noticeable seams and physical strain caused by multiple display panels, which compromise user experience and engagement.
Innovation Solution
An overlay panel with light guides is introduced, featuring a front display portion and a guiding portion with light guides arranged in specific patterns to extend media content over bezel areas, providing a seamless and distortion-free viewing experience from various angles by aligning light guides with display pixels and transferring excitation to cover the bezel portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display panels are arranged side by side to create a large display, then the display area is increased, but noticeable bezel artifacts and seams appear at the edges
Solution Approach 1:
An overlay panel is introduced as an intermediary component between the display panels and the viewer. This overlay panel includes light guides that extend the displayed image content across the bezel areas, effectively mediating the visual transition between panels and concealing the bezel artifacts that would otherwise be visible at the edges.
Solution Approach 2:
The overlay panel utilizes optical properties including refractive index variations and light scattering to modify how light travels from the display panels through the overlay. By controlling the optical path and light distribution, the system creates a seamless visual appearance that masks the physical boundaries and color discontinuities at bezel edges.
2Object-affected harmful factors
If overlay strips with Fresnel lenses are used to cover bezel portions, then the bezel visibility is reduced, but faded seams remain visually perceptible
Solution Approach 1:
The overlay panel is constructed as a composite structure combining multiple materials with different optical properties, including transparent or translucent materials with specific refractive indices, light scattering particles, and potentially multiple layers. This composite construction enables simultaneous achievement of bezel concealment and seamless appearance by distributing and controlling light propagation through different material zones.
3Ease of operation
If conventional display systems are used, then the display setup is simple, but the viewing experience is inconsistent from different viewpoints
Solution Approach 1:
The overlay panel incorporates dynamic light management capabilities through its light guide structure and optical material properties. The system adaptively controls light distribution and scattering based on viewing angle, maintaining consistent image quality and bezel concealment across different observer positions without requiring complex active control mechanisms.
4Area of stationary object
If multiple display panels are used to create a large display, then the display size is increased, but physical strain and eye strain occur during viewing
Solution Approach 1:
The overlay panel creates a homogeneous visual field across the entire multi-panel display surface by uniformly concealing bezel artifacts and maintaining consistent light distribution characteristics. This homogenization of the visual appearance across panel boundaries eliminates distracting artifacts and provides a uniform viewing experience that reduces eye strain during extended viewing of large displays.
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 overlay panel enhances the viewing experience by concealing bezel artifacts, creating a seamless image across multiple panels, and maintaining high display resolution, thus improving user engagement and reducing physical strain.
Implementation Method 1
The plurality of light guides may be arranged such that an input portion of each light guide of the plurality of light guides may be aligned with a set of pixels or sub-pixels of a plurality of pixels present in the display portion of the display device. Furthermore, the plurality of light guides may be arranged such that an output portion of each light guide of the plurality of light guides may be coupled to the front display portion of the overlay panel.
Implementation Method 2
The arrangement of each light guide in the guiding portion may transfers excitation, caused by the set of pixels or sub-pixels, from the input portion to the output portion of each light guide at the front display portion.

AI summary
An overlay panel that includes a front display portion arranged over surface area of a display device. The overlay panel further includes a guiding portion that comprises light guides arranged in a specific pattern. The light guides are arranged such that an input portion of each light guide is aligned with pixels or sub-pixels of the display device and an output portion of each light guide is coupled to the front display portion. The arrangement of each light guide transfers an excitation, caused by the set of pixels or sub-pixels, from the input portion to the output portion and causes the front display portion to display an image that covers a bezel portion and the display portion of the display device. Each pixel in the image is scaled by an equal scaling factor with respect to each pixel in display portion.
