Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display technologies face challenges in generating high-quality arc-shaped display screens, often resulting in a serrated phenomenon that reduces image quality, requiring customization and the use of shading stickers or cutting display panels.
Innovation Solution
A display apparatus and image processing method that includes a processor coupled to a display panel, which receives position and shape information, adjusts display data, and uses an anti-aliasing block with weighting values to scan and adjust pixel or sub-pixel gray levels, effectively eliminating serrations by performing arithmetic operations on the gray levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional technology uses shading stickers or cuts the display panel to generate arc-shaped display screens, then the display screen can achieve arc-shape, but the manufacturing complexity increases and customization is required for different customer needs
Solution Approach 1:
The patent replaces the mechanical approach of using physical shading stickers or cutting panels with a software-based image processing method. The processor applies anti-aliasing algorithms to generate arc-shaped display effects through digital image processing, eliminating the need for physical modifications and customization of hardware components.
2Shape
If conventional technology generates arc-shaped display screens by cutting or shading, then the arc-shape is achieved, but serrated phenomenon appears in the arc-shape portion reducing display quality
Solution Approach 1:
The patent replaces physical cutting or shading methods with digital anti-aliasing image processing. The processor applies weighting algorithms to pixel gray levels along the arc boundary, smoothly transitioning between colors to eliminate the serrated effect and produce high-quality arc-shaped displays without physical modifications.
Solution Approach 2:
The patent changes the gray level parameters of pixels along the arc boundary by applying weighting factors. The anti-aliasing block modifies pixel intensity values based on their position relative to the arc shape, creating smooth transitions that eliminate serrated phenomena and improve display precision.
3Shape
If conventional technology uses shading stickers to create arc-shapes, then the display screen achieves the desired shape, but the process requires customization for different customer needs increasing device complexity
Solution Approach 1:
The patent replaces the manufacturing process of applying custom shading stickers with a software-based anti-aliasing algorithm. The processor automatically generates arc-shaped displays through image processing, eliminating the need for manual customization and simplifying the manufacturing process for different arc configurations.
