Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Optical aberrations such as chromatic aberration and distortion in display systems, which require correction to ensure accurate image display, currently burden the graphic processing unit with resource allocation for correction calculations, increasing its loading and cost.
Innovation Solution
A display apparatus and method where the display driver, equipped with optical aberration correction capabilities, performs aberration correction on images before they are displayed, reducing the computational load on the graphic processing unit and allowing it to focus on other functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If optical aberration correction is performed by the graphic processing unit, then image display accuracy is improved, but the loading and cost of the graphic processing unit increase
Solution Approach 1:
The patent divides the optical aberration correction function into separate modules for different types of aberrations (distortion, chromatic aberration, etc.), allowing the graphic processing unit to handle only critical corrections while other corrections are performed by the display driver or optimized through lookup tables, thereby reducing its loading
Solution Approach 2:
The patent pre-calculates correction data and stores it in lookup tables during system initialization or manufacturing, so that during actual display operations, the graphic processing unit only needs to perform simple table lookups rather than complex real-time calculations, significantly reducing its computational loading
2Measurement precision
If optical aberration correction is performed by the graphic processing unit, then image display accuracy is improved, but the cost of the display apparatus increases
Solution Approach 1:
The patent separates correction functions between the graphic processing unit and display driver, allowing lower-cost graphic processing units to be used since they don't need to perform all correction calculations, while the display driver handles routine corrections
Solution Approach 2:
By pre-calculating and storing correction data in lookup tables, the patent eliminates the need for expensive real-time correction algorithms in the graphic processing unit, reducing overall system cost while maintaining correction accuracy
3Measurement precision
If the graphic processing unit performs aberration correction, then correction accuracy is maintained, but the performance of the display apparatus decreases due to increased loading
Solution Approach 1:
The patent divides correction tasks between the graphic processing unit and display driver, with the latter handling routine corrections that would otherwise burden the graphic processing unit, thereby improving overall system performance
Solution Approach 2:
By pre-computing correction data and storing it in lookup tables, the patent enables fast retrieval during display operations, maintaining correction accuracy while significantly improving processing speed and overall apparatus performance
