Display Panel Data-Register Hold for Faster Row Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in improving the frame rate and reducing the size of image files due to the need to repeatedly update driving voltages for each pixel row, which complicates the update process.
Innovation Solution
The display panel employs a method where driving circuits and data registers maintain previously set driving voltages when subsequent rows have identical pixel values, disabling input terminals to avoid redundant updates, and utilizes a novel driving signal format to optimize the update process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driving voltages are updated for every pixel row in every frame, then the display quality is maintained, but the update rate is reduced and processing time increases
Solution Approach 1:
The patent extracts only the changed pixel data from the entire frame and transmits only these differences to the display panel. By comparing pixel values between frames and identifying only the changed regions, the system eliminates redundant transmission of unchanged pixel data, thereby improving update rate while maintaining display quality.
Solution Approach 2:
Instead of updating all pixel rows in every frame, the patent applies partial action by updating only those pixel rows that contain changed data. The system identifies specific changed pixel positions within rows and updates only those particular pixels, reducing the overall update workload while ensuring that all visible changes are properly displayed.
2Loss of information
If all pixel rows are updated in every frame, then complete image information is displayed, but the processing time and data transmission volume increase
Solution Approach 1:
The patent extracts only the essential changed information from the image data by comparing consecutive frames. It identifies and extracts only the pixel values that have changed, discarding redundant unchanged data, thereby reducing processing time while preserving all necessary image information for accurate display.
Solution Approach 2:
The patent uses a copying mechanism where unchanged pixel data from the previous frame is retained and reused. Instead of reprocessing all pixel data, the system copies previously processed pixel values and only reprocesses the changed portions, significantly reducing processing time while maintaining complete image information integrity.
3Manufacturing precision
If driving voltages are written to all data registers in each row, then accurate pixel control is achieved, but the complexity of the update process increases
Solution Approach 1:
The patent segments the pixel array into multiple rows and further segments each row into individual pixel units. By organizing the update process in a hierarchical segmented manner, the system can selectively update only the necessary pixel units in specific rows, maintaining precise pixel control while reducing overall update process complexity through modular organization.
Solution Approach 2:
The patent applies local quality by treating different pixel rows and individual pixels differently based on their change status. Changed pixels receive full update processing while unchanged pixels are skipped, allowing the system to maintain high pixel control accuracy for changed regions while reducing complexity through selective processing based on local change characteristics.

AI summary
An image display method, comprising: setting multiple first driving voltages on a first row of multiple pixel units according to a first driving signal by a driving circuit and multiple data registers; and setting multiple second driving voltages on a second row of the pixel units according to a second driving signal by the driving circuit and the data registers. Wherein setting the second driving voltages of the second row of the pixel units comprises: when one of the second driving voltages is equal to one of the first driving voltages, and both correspond to the same one of the data registers, disabling an input terminal of the same one of the data registers, so that the same one of the data registers maintains one of the first driving voltages as one of the second driving voltages.
