Transparent Display Camera Region Diffraction Spot Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a camera region into display panels for improved screen ratio and aesthetics leads to light diffraction issues, causing unwanted spots in images due to the gaps between pixel units, which cannot be fully resolved by reducing pixel density without compromising display quality.
Innovation Solution
A transparent display region is incorporated within the main display area, equipped with an image acquisition component that captures multiple images of a moving object at intervals, merging them using an algorithm to eliminate or weaken diffraction spots, thereby enhancing the display effect while maintaining pixel density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If pixel units are disposed in the camera region to improve screen ratio and aesthetics, then the display area increases, but light diffraction occurs due to gaps between pixel units causing appearance of light spots
Solution Approach 1:
The camera region is segmented into multiple sub-regions with different pixel density arrangements. By dividing the uniform pixel grid into zones with varying densities, the patent creates regions where diffraction patterns differ, allowing algorithmic merging to eliminate spots while maintaining overall high display area
Solution Approach 2:
Different regions of the camera area are assigned different pixel densities and arrangements. The patent applies local quality by making pixel density non-uniform across the camera region, with some areas having higher density and others having lower density, thereby creating spatial variation in diffraction characteristics that enables spot elimination through image merging
2Object-affected harmful factors
If pixel density is reduced to eliminate diffraction spots, then light diffraction is reduced, but display quality deteriorates
Solution Approach 1:
The patent dynamically adjusts pixel density in different regions rather than using a static uniform density. By making pixel density variable and adaptive across the camera region, the system can maintain high display quality in critical areas while reducing diffraction in others, and use algorithmic processing to combine these dynamic variations for spot elimination
Solution Approach 2:
The patent changes the pixel density parameter spatially across the camera region. By varying this key parameter - creating non-uniform pixel distribution with different densities in different areas - the system achieves both high display quality where needed and reduced diffraction where pixel density is lowered, with algorithmic merging combining these effects

Function Achieved in This Case
This approach effectively reduces or eliminates diffraction spots in images, improving the display quality and user experience by merging images with different diffraction patterns, ensuring consistent and high-quality imaging across the display panel.
Implementation Method 1

Implementation Method 2
a slender gap is formed between neatly arranged pixel units, which is easy to cause diffraction of light, resulting in appearance of light spots
