Panel Display Timing for High-Refresh Pixel Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High refresh rates in panel displays lead to insufficient charging duration for pixel rows, resulting in incomplete display of pixel values and reduced display effect.
Innovation Solution
Adjust the start moment and period of the input latch signal to increase the theoretical charging duration of pixel rows, allowing for complete display of pixel values by configuring M/N real-pixel rows and adjusting image stream data to (M/N)*Z resolution, with mixed-pixel rows displaying combined pixel values when necessary.

Engineering Contradiction Analysis
1Productivity
If the refresh rate of the panel is increased, then the display effect of the panel is improved, but the charging duration of a single pixel row is shortened
Solution Approach 1:
The patent divides the pixel rows into M/N real-pixel rows with N-1 virtual pixel rows between them. This segmentation allows the system to selectively charge only the real-pixel rows while the virtual rows serve as buffer zones, thereby maintaining adequate charging duration for real pixels even at high refresh rates.
Solution Approach 2:
Instead of charging all pixel rows equally, the patent applies partial charging action by focusing charging resources only on M/N real-pixel rows. This partial action ensures sufficient charging duration for the real pixels that need to display image data, while virtual pixel rows are not charged during this period.
2Productivity
If the refresh rate of the panel is increased, then the display effect is improved, but the actual charging duration becomes insufficient
Solution Approach 1:
The patent segments pixel rows into real and virtual categories, where only real-pixel rows receive charging and display image data. This segmentation ensures that the limited charging time at high refresh rates is dedicated to the rows that actually need to display information, maintaining display completeness.
Solution Approach 2:
Virtual pixel rows act as intermediary elements between real pixel rows. They are not charged but serve as buffer zones that help maintain the timing and synchronization of the display system, allowing real pixel rows to be charged adequately even at high refresh rates.
3Productivity
If the refresh rate configuration is updated to W*N, then the display effect is enhanced, but the system complexity increases
Solution Approach 1:
The patent introduces a real-pixel row determination module that segments pixel rows into real and virtual categories based on simple mathematical relationships (M/N real rows out of M total rows). This segmentation approach allows high refresh rate operation without requiring complex hardware modifications, as the distinction between real and virtual rows can be implemented through simple control logic.

AI summary
The present disclosure provides a panel display method, apparatus and system, a device and a storage medium. The method includes: when determining that a refresh rate configuration of a panel is W*N, determining M/N real-pixel rows for the panel, where N−1 pixel rows are presented between adjacent real-pixel rows of the real-pixel rows; where the panel comprises M pixel rows, and a resolution of the panel is M*Z; N≥2; acquiring image stream data with a refresh rate of W*N and M/N rows of pixel values; where an image resolution of the image stream data is (M/N)*Z; adjusting a start moment and a period of an input latch signal of the panel, so that the M/N real-pixel rows display the M/N rows of pixel values in the image stream data row by row, where a theoretical charging duration of a single real-pixel row is greater than or equal to 1/(W*M) second.
