Multi-Panel Backlit Display for Dynamic Color and Shade Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display assemblies for art and advertising lack the ability to dynamically change the color or intensity of displayed images effectively, relying on static backlighting and limited color spectra.
Innovation Solution
A backlit display assembly comprising multiple panels with transparent and opaque sections, combined with a light source emitting RGB and white light, allows for dynamic color changes by controlling light passage through the panels, enabling a wide range of colors and shades to be displayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static backlighting is used in display assemblies, then the structure is simple and cost-effective, but the ability to dynamically change color or intensity of displayed images is limited
Solution Approach 1:
The display assembly is divided into multiple panels (first panel, second panel, third panel) with different optical properties (transparent, opaque, translucent). Each panel can be independently configured with specific color characteristics, allowing selective control of light passage to achieve dynamic color changes without requiring a completely complex system redesign
Solution Approach 2:
Different portions of the display assembly have different optical properties - some panels are transparent in certain regions and opaque in others. The light source emits different colors (RGB) that can be selectively filtered by different panel sections, enabling local color variation and dynamic color changing capabilities in specific areas of the display
2Illumination intensity
If multiple panels with different transparency are used, then color variety and intensity control are enhanced, but the structural complexity increases
Solution Approach 1:
The display assembly uses a nested structure where multiple panels are stacked together (first panel, second panel, third panel arranged in sequence). Each panel is positioned adjacent to the previous one, creating a layered configuration where light passes through multiple layers sequentially. This nested arrangement allows for sophisticated color and intensity control while maintaining a compact, integrated structure
Solution Approach 2:
The display assembly combines different panel materials with varying optical properties (transparent, opaque, translucent) to create a composite structure. This composite approach enables fine-tuned control over light transmission, color mixing, and intensity modulation by strategically selecting and arranging materials with complementary characteristics

Function Achieved in This Case
Enables selected elements in a sign or image to change colors or shades, providing enhanced viewing experiences with a wide range of colors and nuanced intensity control, while maintaining cost-effectiveness and flexibility in panel materials and lighting sources.
Implementation Method 1
light from the light source passes through the first transparent portion of both the first panel and the second panel
Implementation Method 2
a light source that includes at least a red light emitting diode, a green light emitting diode, and blue light emitting diode
Implementation Method 3
a second panel including a first transparent portion of a first color, a second transparent portion of a second color, and an opaque portion so that light from the light source does not pass through a corresponding portion of the first panel
