E-Ink Cursor Refresh Sequencing for Continuous Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
E-ink screens refresh images and cursors at discrete intervals, leading to discontinuous cursor movement due to long refresh times, which affects display quality and user experience.
Innovation Solution
Implement a method and electronic device with a controller to determine a target refresh signal based on cursor changes, allowing the display module to perform multiple refreshes using a sequence of signals to smoothly transition between images, ensuring continuous cursor movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the e-ink screen refreshes a frame of image according to a plurality of refresh unit time lengths, then the image can be displayed, but the cursor movement trajectory becomes discontinuous due to the relatively long refresh time length
Solution Approach 1:
The patent segments the cursor refresh process from the full image refresh process. Instead of refreshing the entire image frame at discrete intervals, the cursor is refreshed selectively at specific time points within the refresh unit time lengths. This segmentation allows the cursor to be updated more frequently than the full image, creating a continuous cursor movement trajectory while maintaining the power-efficient discrete refresh schedule of the e-ink display.
2Stability of the object's composition
If the cursor is refreshed at the corresponding time length with the image, then the display is synchronized, but the cursor movement appears discontinuous
Solution Approach 1:
The patent introduces dynamic, selective refreshing where the cursor refresh timing is not fixed but adapted based on cursor movement detection. When cursor movement is detected, the system dynamically inserts additional cursor refresh operations between full image refresh cycles. This dynamic approach maintains display synchronization while ensuring the cursor is updated at appropriate moments to reflect movement, creating smooth visual trajectories without requiring continuous full-frame refreshes.

AI summary
An image output control method includes receiving a first image sent by a graphics processor, receiving cursor information generated based on a cursor change, determining a target refresh signal according to the first image, a second image, and the cursor information, and outputting the target refresh signal to the display module. The target refresh signal includes at least one refresh signal of a plurality of refresh signals. The plurality of refresh signals are used to cause a display module to perform a plurality of refreshes to transition from displaying the second image to displaying the first image.
