Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display technologies face issues with jagged image edges due to irregular pixel distribution on stacked screens, leading to suboptimal display effects and user experience.
Innovation Solution
An image display method that involves obtaining initial sampling values for a first screen, correcting current region sampling values based on a mapping relationship with previous region correction values, and determining second data for a second screen to create an overlapped stacked display, thereby improving image accuracy and reducing memory usage.

Engineering Contradiction Analysis
1Adaptability or versatility
If image data is split into two parts for stacked screen display, then the display can be implemented on overlapping screens, but jagged image edges occur due to irregular pixel distribution
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing correction values for each region before the actual display process. The system divides the image into multiple regions, calculates correction values for each region based on the irregular pixel distribution, and stores these correction values in a lookup table. During display, these pre-computed correction values are applied to adjust the sampling data, thereby eliminating jagged edges without requiring complex real-time calculations.
Solution Approach 2:
The patent implements local quality by treating different regions of the image differently. Instead of applying a uniform correction approach, the system divides the image into multiple regions (e.g., first region, second region, third region) and calculates region-specific correction values based on the local pixel distribution characteristics. Each region's correction values are stored separately and applied only to that region's data, allowing precise local adjustments to compensate for irregular pixel distribution in each specific area.
2Manufacturing precision
If region sampling values include previous region correction values and current region sampling values, then image display quality is improved, but data processing complexity increases
Solution Approach 1:
The patent reduces data processing complexity by performing all necessary calculations and corrections in advance. The system pre-calculates correction values for each region based on the image data and stores them in a lookup table before the actual display process. During display, the system simply retrieves the pre-computed correction values and applies them to the sampling data, avoiding complex real-time calculations and reducing the processing burden during the actual image display.
Solution Approach 2:
The patent introduces an intermediary structure in the form of a lookup table that stores correction values. This lookup table acts as a mediator between the image data and the final display output. Instead of performing complex calculations during the display process, the system uses the lookup table to quickly retrieve pre-computed correction values, which are then applied to the sampling data. This intermediary structure simplifies the data processing workflow and reduces computational complexity during display.

AI summary
An image display method includes: obtaining image data of a target image, and obtaining an initial sampling value of a first screen according to the image data, wherein the initial sampling value includes region sampling values of at least two target regions in the first screen, and the region sampling values include a previous region correction value and a current region sampling value; correcting the current region sampling value in a target region sampling value, based on a mapping relationship between the previous region correction value and the target region sampling value, to obtain first data; and determining second data corresponding to a second screen according to the first data, to realize displaying of the target image in a stacked screen according to the first data and the second data, wherein the stacked screen is formed by the first screen and the second screen in an overlapped manner.
