Spliced Display Panel Brightness Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current spliced display screens experience brightness differences at splicing positions, affecting the overall display effect due to varying peak brightness parameters across adjacent display panels.
Innovation Solution
A display method and apparatus that segment image data into sub-image data for multiple display panels, calculate initial and target peak brightness parameters for each panel, and adjust display based on these parameters to minimize brightness differences between adjacent panels, using a formula that considers adjacent panel brightness to synchronize peripheral region brightness.

Engineering Contradiction Analysis
1Area of stationary object
If multiple display panels are spliced together to form a large-screen display, then the display area is increased, but brightness differences appear at splicing positions
Solution Approach 1:
The patent applies local quality by differentiating the treatment of central and peripheral regions of display panels. Peripheral regions adjacent to splicing positions receive adjusted peak brightness parameters to compensate for brightness differences, while central regions maintain original parameters. This localized adjustment ensures uniform brightness across splicing positions without affecting the overall display area.
Solution Approach 2:
The patent changes the peak brightness parameter (PBP) dynamically based on the position of each display panel. By calculating and applying position-specific PBP values to peripheral regions of panels at splicing positions, the system adjusts illumination intensity parameters to eliminate brightness differences while maintaining the expanded display area.
2Illumination intensity
If peak brightness parameters are adjusted to reduce brightness differences, then brightness uniformity is improved, but display complexity increases
Solution Approach 1:
The patent segments the display system into distinct regions (central and peripheral) and processes peak brightness parameters for each region separately. By dividing the calculation into manageable segments and applying different PBP adjustments only where needed (at splicing positions), the system achieves brightness uniformity without requiring complex system-wide recalculations.
Solution Approach 2:
The patent applies partial action by adjusting peak brightness parameters only for peripheral regions of display panels at splicing positions, rather than recalibrating the entire display system. This selective adjustment reduces computational complexity while effectively addressing brightness uniformity issues at critical locations.
