Digital Bezel Light Guide for 3D Display Effects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with image displays in the rim area are expensive to manufacture and fail to stimulate purchasing desire due to limited design effects, as they only display different images in the same plane.
Innovation Solution
A display device digital bezel with an optical pickup member that radiates images from the bezel area upwards, using light guides with a cladding layer and uneven scratched surfaces to create a three-dimensional effect, reducing manufacturing costs and enhancing design and promotional impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a second display panel is disposed in the rim area to display different images, then the bezel can display images, but the manufacturing cost increases and special three-dimensional effects cannot be achieved
Solution Approach 1:
The patent uses a light guide to optically copy and transfer the image from the bezel area to a elevated display surface. Instead of using a second display panel, the system projects the bezel image through the light guide to create a virtual image in three-dimensional space, achieving the display function without the complexity and cost of additional display hardware
Solution Approach 2:
The patent transforms the two-dimensional bezel image into a three-dimensional display by using the light guide to radiate the image upwards. The image is displayed not only on the bezel plane but also elevated in the vertical dimension, creating a prominent three-dimensional effect that enhances visual impact without requiring complex multi-panel structures
2Device complexity
If images are displayed only in the same plane on the bezel, then the structure remains simple, but the three-dimensional effect and purchasing desire stimulation are limited
Solution Approach 1:
The light guide radiates the bezel image upwards to create a virtual image elevated above the bezel surface. This adds a vertical dimension to the display, transforming a flat two-dimensional image into a three-dimensional visual experience that maintains structural simplicity while achieving prominent depth effects
3Shape
If a light guide is used to radiate the image upwards, then the three-dimensional effect is enhanced, but the light guide structure must be precisely manufactured
Solution Approach 1:
The patent optimizes the light guide parameters including its thickness (5-20mm), refractive index, and surface characteristics to achieve effective image radiation. By carefully selecting and adjusting these parameters, the system achieves prominent three-dimensional effects while maintaining manufacturability through standardized production processes for light guides
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 increases the three-dimensional effect of images on the bezel, improving design and promotional impacts while reducing manufacturing costs, thereby stimulating purchasing desire and enhancing advertising and game-event effects.
Implementation Method 1
Each light guide may include a cladding layer configured to surround an outer surface of the light guide so that the image incident on the light-incident surface is totally reflected and emitted to the light-emitting surface
Implementation Method 2
The light-emitting surface of each light guide may be formed into an uneven scratched surface to expand a viewing angle of the image incident on the light-incident surface

AI summary
A digital bezel of a display device includes: a display device including a bezel region for displaying an image different from an effective screen by dividing a frame portion of an effective screen of the display device; and an optical pick-up member, mounted in the bezel region, for picking up an image displayed in the bezel region in a straight line by a predetermined thickness to three-dimensionally highlight the image. As such, the three-dimensional effect of the image can be emphasized and manufacturing costs can be reduced.
