Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display assemblies struggle to create a visually seamless three-dimensional effect across multiple planes, often requiring multiple display panels or stereoscopic methods that are costly or require special viewer equipment.
Innovation Solution
A display assembly featuring a lens with varying thickness and an optically clear adhesive with varying thickness, which creates a three-dimensional appearance by altering the presentation of images and video in proximal viewing areas relative to the distal viewing area, making physical objects appear embedded in the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If multiple display panels are used to create perceived physical depth, then the three-dimensional effect is improved, but the manufacturing cost and device complexity increase
Solution Approach 1:
The patent applies local quality by creating varying adhesive thickness in specific regions between the lens and display panel. The adhesive layer has different thicknesses in different areas, which selectively alters light refraction in those local regions to create the perception of physical depth for specific elements while keeping the overall structure simple.
Solution Approach 2:
The patent changes the physical parameter of adhesive thickness to create depth perception. By varying the thickness of the optically clear adhesive layer in different regions, the optical path length changes, causing light to refract differently and creating the illusion that certain elements are at different depths from the viewer.
2Shape
If stereoscopic display methods are used to create three-dimensional effect, then the depth perception is improved, but the requirement for special viewer equipment increases
Solution Approach 1:
The display assembly performs the depth creation function itself through the varying adhesive thickness structure. The system is self-sufficient in creating the three-dimensional effect without requiring external assistance from special glasses or electronic shuttering devices, making it universally viewable with naked eyes.
Solution Approach 2:
The patent replaces complex mechanical or electronic stereoscopic systems with a simple optical structure based on light refraction through varying adhesive thickness. This substitution eliminates the need for mechanical shuttering mechanisms or electronic synchronization with special glasses.
3Shape
If images and video are processed to create depth illusion on multiple panels, then the three-dimensional appearance is improved, but the processing complexity and computational resources increase
Solution Approach 1:
The patent replaces complex image processing and computational algorithms with a passive optical structure. Instead of processing images to create depth illusions, the varying adhesive thickness physically refracts light to create the depth effect directly, eliminating the need for complex software processing.

Function Achieved in This Case
The solution provides a cost-effective and seamless three-dimensional experience without the need for multiple display panels or special viewer equipment, effectively embedding physical objects in the viewable display.
Implementation Method 1
An optically clear adhesive layer is provided on a surface of the lens surface. The optically clear adhesive layer is selectively applied. The digital data is re-rendered based on the selective application of the optically clear adhesive layer.
Implementation Method 2
A lens extends parallel to and in a spaced relationship with the display panel to define a distal viewing area. The lens has a varying lens thickness for altering the presentation of the images and video displayed on the display panel

AI summary
A display assembly for showing perceived depth is provided. The display includes a display panel for displaying images and video. A lens extends parallel to and in a spaced relationship with the display panel to define a distal viewing area. An optically clear adhesive is partially disposed between the display panel and the lens to define a plurality of proximal viewing areas. The lens has a varying lens thickness for altering the presentation of the images and video displayed on the display panel in the proximal viewing areas relative to the presentation of the images and video displayed on the display panel in the distal viewing area to create a three dimensional appearance of the images and video. A controller is configured to tailor the images and video presented in the distal viewing area relative to the images and video in the proximal viewing areas to enhance the three dimensional appearance.
