Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display technologies result in jagged images at the edges of special-shaped displays due to rectangular pixels not matching the display's edges, leading to reduced image quality.
Innovation Solution
A display panel with a boundary line dividing it into a display region and a non-display region, where pixels are composed of sub-pixels with area uniformity, and shielding blocks or brightness adjustments are applied based on area uniformity within predetermined ranges to address jagged image issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional rectangular pixels are used in special-shaped displays, then the display structure can be simplified, but jagged images appear at the edge and image quality deteriorates
Solution Approach 1:
The patent applies different treatments to different regions of pixels based on their area uniformity. Pixels with area uniformity within a first predetermined range receive shielding blocks, while pixels with area uniformity outside this range have their brightness adjusted. This local differentiation resolves the contradiction by maintaining simple rectangular pixel structures while improving edge image quality through region-specific corrections.
Solution Approach 2:
The patent changes the brightness parameter of pixels based on their area uniformity. By adjusting the brightness of pixels with area uniformity outside the predetermined range, the patent compensates for the jagged edge effect without changing the physical pixel structure, thus maintaining structural simplicity while improving image quality.
2Manufacturing precision
If shielding blocks are added to pixels with area uniformity within a predetermined range, then jagged images at the edge are reduced, but device complexity increases
Solution Approach 1:
Shielding blocks are selectively applied only to pixels with area uniformity within a first predetermined range, rather than uniformly to all pixels. This local application reduces the overall complexity increase while effectively addressing jagged images at specific edge regions where the problem occurs.
Solution Approach 2:
The patent segments pixels into different categories based on their area uniformity. By dividing pixels into those within the predetermined range (receiving shielding blocks) and those outside the range (having brightness adjusted), the patent manages complexity through systematic classification and differentiated treatment.
3Manufacturing precision
If brightness of pixels is adjusted according to area, then jagged images are reduced, but manufacturing precision requirements increase
Solution Approach 1:
The patent uses brightness adjustment as a compensatory parameter change for pixels with area uniformity outside the predetermined range. This approach addresses jagged images through software/control层面的调整 rather than physical structure changes, but requires precise measurement of pixel area uniformity to determine which pixels need brightness adjustment.
Solution Approach 2:
The patent implements a feedback mechanism where pixel area uniformity is measured and used to determine subsequent treatment (shielding blocks or brightness adjustment). This feedback loop ensures that brightness adjustment is applied precisely to the right pixels, managing the increased measurement precision requirements through systematic control.
