Innovation Solution
A display device comprising pixel island groups, lenses, a positioning module, and a gate driving chip that allows for different scanning modes, enabling row-by-row scanning in the gaze area and simultaneous scanning of multiple rows in the non-gaze area, along with a data acquisition and processing unit to generate pixel values based on RGB image data.

Engineering Contradiction Analysis
1Manufacturing precision
If high-resolution display devices increase data transmission requirements to improve display quality, then the resolution and display quality are improved, but the refresh rate decreases
Solution Approach 1:
The display screen is segmented into multiple scanning zones (first scanning zone and second scanning zone) with different scanning strategies. The first scanning zone uses row-by-row sequential scanning while the second scanning zone uses simultaneous multi-row scanning, allowing the system to maintain high resolution in the focus area while improving overall refresh rate through differentiated scanning approaches.
Solution Approach 2:
Different scanning modes are applied to different regions of the display screen based on local requirements. The first scanning zone (where users typically focus) maintains traditional sequential scanning for high quality, while the second scanning zone (peripheral areas) uses simultaneous scanning for higher speed, optimizing the balance between quality and refresh rate locally.
2Manufacturing precision
If the display device scans sub-pixel units line by line to ensure display quality, then the display quality is maintained, but the data transmission amount increases and refresh rate decreases
Solution Approach 1:
The scanning process is segmented into two distinct modes: sequential row-by-row scanning for the first scanning zone and simultaneous multi-row scanning for the second scanning zone. This segmentation allows the system to reduce overall data transmission by processing multiple rows concurrently in the second zone while maintaining quality in the first zone.
Solution Approach 2:
The patent applies simultaneous scanning to the second scanning zone where full sequential scanning quality is less critical. By using partial sequential scanning (only in the first zone) and partial simultaneous scanning (in the second zone), the system achieves a compromise that reduces total data transmission while maintaining acceptable display quality.
3Quantity of substance
If the display device uses simultaneous scanning of multiple lines in the non-gaze area to reduce data transmission, then the data transmission amount is reduced, but the sub-pixel units on both sides of the gaze area cannot achieve simultaneous scanning
Solution Approach 1:
The display screen is divided into multiple independently controllable scanning zones that can operate with different scanning modes simultaneously. This segmentation enables the system to apply row-by-row scanning to some zones and simultaneous multi-row scanning to other zones, providing flexible adaptation to different display requirements and reducing overall data transmission.
Solution Approach 2:
The scanning system dynamically adjusts the scanning mode for different zones based on real-time requirements. The gate driving chip can independently control the scanning timing and mode for each zone, allowing the system to optimize data transmission by using simultaneous scanning in appropriate zones while maintaining quality in others.
