Display Edge Correction via Integrated Grayscale Data Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Full-screen and special-shaped display screens often experience contour jaggies at their edges due to round corners, which degrade the displaying effect and viewing experience, and existing edge correction algorithms are complex and resource-intensive, limiting their applicability to standard round corners only.
Innovation Solution
An image processing method that uses a pre-created correction data table to integrate displaying correction data and edge correction data for pixels at the edge portion, allowing for flexible edge correction on any shaped screen without increasing logic resource occupation, by determining pixel positions and applying appropriate correction data based on markers in the table.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If round corners are used to reduce bezel area, then the active area proportion increases, but contour jaggies occur at the edge portion
Solution Approach 1:
The patent applies local quality by differentiating correction processing between edge portion pixels and non-edge portion pixels. A marker is used to identify edge portion pixels, and different correction data are applied: integrated correction data (displaying correction data + edge correction data) for edge pixels, and only displaying correction data for non-edge pixels. This localized approach removes contour jaggies at edges while maintaining overall display quality.
2Object-generated harmful factors
If existing edge correction algorithms are used, then contour jaggies are removed, but logic resource occupation increases and applicability is limited to standard round corners
Solution Approach 1:
The patent merges displaying correction data and edge correction data into integrated correction data for edge portion pixels. This combination is stored in a correction data table along with markers that identify edge pixels. By pre-integrating the correction data and using markers for identification, the system avoids complex runtime calculations and reduces logic resource occupation while maintaining effectiveness for various screen shapes.
Solution Approach 2:
The patent performs preliminary action by pre-creating a correction data table that contains markers and integrated correction data for all pixels before actual display operation. This pre-processing step identifies edge portion pixels and stores their corresponding correction data in advance, eliminating the need for complex real-time edge detection and correction calculations during display, thus reducing logic resource occupation.
3Productivity
If integrated correction data are used for edge pixels, then correction processing efficiency improves, but data storage requirements increase
Solution Approach 1:
The patent segments the correction data storage by creating a correction data table that stores integrated correction data only for edge portion pixels (identified by markers), while non-edge pixels use standard displaying correction data. This segmentation approach allows efficient correction processing for edge pixels without unnecessarily increasing storage requirements for all pixels, as only edge pixels require the integrated correction data.

AI summary
Disclosed are an image processing method, apparatus, system and a display device, which can be allowed to perform correction processing on the grayscale of each of the pixels, without any limitation on the shape of the display panel, and have relatively high flexibility. In addition, because the pre-created correction data table has the pixel position, the marker and the correction data contained herein, the correction data are correction data integrated from displaying correction data and edge correction data if the pixel position belongs to the preset edge portion and the correction data are the displaying correction data if the pixel position is other than that belonging to the edge portion, the displaying correction data and the correction data integrated from the displaying correction data and the edge correction data are contained in the correction data table, so that the logic resource occupied in the system can be effectively reduced.
