Solution Overview
Problem
Current electronic display technologies struggle to produce large, high-quality displays that mimic the organic and natural appearance of traditional images, as they are often too bright and unnatural, and are prohibitively expensive to scale up.
Innovation Solution
A multi-layered display apparatus comprising a mesh layer with selectively controllable LEDs and a screen layer that absorbs backlighting, combined with front projection, to create a composite image that is scalable, energy-efficient, and realistic, resembling traditional art pieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional LED/LCD, OLED, or QLED display technologies are used, then color, contrast, and resolution are enhanced, but the displays are prohibitively expensive to scale to large formats
Solution Approach 1:
The patent uses a camera to capture the reference image and creates a digital copy that is then projected onto the screen. This allows the display to replicate the appearance of traditional images without using expensive conventional LED/LCD, OLED, or QLED technologies for large formats
Solution Approach 2:
The patent replaces the mechanical assembly of multiple expensive LED panels with a projection system that uses optical mechanisms to display images on a large screen, significantly reducing manufacturing costs while maintaining display quality
2Illumination intensity
If digital images are displayed using traditional projectors or raster-based displays, then images can be shown, but they appear too bright, unnatural, and unrealistic compared to traditional images
Solution Approach 1:
The patent dynamically adjusts projection parameters including brightness, contrast, and color balance to match the reference image characteristics. The system modifies these parameters in real-time to eliminate the unnatural appearance of digital projections while maintaining visibility
Solution Approach 2:
The system captures the projected image with a camera, analyzes the actual appearance, and uses this feedback to automatically adjust projection parameters. This closed-loop control ensures the displayed image matches the natural appearance of traditional images by compensating for projector characteristics
3Area of stationary object
If multiple LED panels are assembled to create large format displays, then large displays can be produced, but manufacturing variations cause different colors and brightness levels across panels
Solution Approach 1:
The camera captures the entire large-format display and the system analyzes color and brightness variations across different panels. This feedback is used to automatically adjust projection parameters for each region, compensating for manufacturing variations and achieving uniform appearance across the entire large display
