Solution Overview
Problem
Current 3D display technology on mobile devices suffers from low pixels per inch, limited information display, and small 3D viewing angles.
Innovation Solution
A 3D display substrate is designed with sub-pixels divided into multiple sub-portions and corresponding plano-convex lenses, allowing for adjustable grayscale to form multi-view 3D images without reducing original display resolution, and includes a driver and switcher for switching between 3D and 2D display modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If 3D display technology is applied on mobile devices using conventional methods, then 3D display function is achieved, but pixels per inch is low and display resolution is reduced
Solution Approach 1:
Each sub-pixel is divided into multiple sub-pixel sub-portions (e.g., 2x2=4 portions) that can be independently controlled. This segmentation allows the system to create multiple virtual pixels within the physical sub-pixel area, thereby increasing pixels per inch without reducing the actual display resolution. The driver independently drives each sub-pixel sub-portion to display different grayscale images, forming multi-view 3D display images.
Solution Approach 2:
The patent introduces a temporal dimension by rapidly switching between different grayscale configurations of sub-pixel sub-portions to create the perception of multiple pixels. By utilizing time-multiplexed display of different grayscale levels across sub-pixel sub-portions, the system achieves higher effective pixels per inch while maintaining the original physical display resolution.
2Loss of information
If conventional 3D display methods are used, then 3D display is achieved, but the amount of information displayed is small and viewing angles are limited
Solution Approach 1:
The driver dynamically adjusts the grayscale levels of different sub-pixel sub-portions based on the desired view direction. By rapidly switching grayscale configurations and utilizing the persistence of vision, the system creates multiple virtual viewing angles and increases the amount of displayable information. This dynamic control allows viewers to see different images from different angles, effectively expanding viewing angles and information capacity.
3Productivity
If sub-pixels are divided into multiple sub-portions for 3D display, then pixels per inch increases, but device complexity increases
Solution Approach 1:
The driver is designed with multi-functionality to handle both conventional 2D display modes and advanced 3D display modes. By implementing a unified control architecture that can dynamically switch between different display modes (2D, multi-view 3D, sequential 3D), the system achieves high pixels per inch without proportionally increasing device complexity. The same hardware infrastructure supports multiple display functions through software-controlled grayscale modulation.
