Quincunx Video Stream Generation for High-Resolution Light Modulating Backplanes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light modulating backplanes face limitations in achieving high resolution due to the size of pixel control circuits, leading to increased cost and power consumption, and require an efficient method to generate suitable video streams for high-resolution displays.
Innovation Solution
The generation of quad-quincunx video streams is achieved by creating specific types of quincunx fields from high-resolution video frames, utilizing configurable multi-electrode pixels and interlacing schemes that allow a single pixel control circuit to control multiple pixels across different frames, reducing the number of required pixel control circuits and enhancing effective resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional light modulating backplanes use one pixel control circuit per pixel to achieve high resolution, then resolution is improved, but the size of pixel control circuits increases leading to increased cost and power consumption
Solution Approach 1:
A single pixel control circuit is designed to control multiple dot electrodes across different frames by changing its output state. The pixel control circuit functions as both a control element for individual pixels and as a shared resource for multiple pixels through time-multiplexed control, reducing the total number of control circuits required while maintaining high resolution capability
Solution Approach 2:
The system uses interlaced scanning with alternating odd and even frames. Pixel control circuits are activated periodically to control different sets of dot electrodes in different frames. This periodic activation allows the same control circuit to serve multiple pixels at different time intervals, reducing the overall number of control circuits needed
2Device complexity
If the number of pixel control circuits is reduced to lower cost and power consumption, then device complexity is reduced, but achieving high resolution becomes difficult
Solution Approach 1:
The patent introduces the time dimension by using interlaced scanning with alternating odd and even frames. Instead of controlling all pixels simultaneously in space, the system controls pixels sequentially in time. This temporal dimension allows fewer control circuits to manage more pixels by activating them at different time intervals, thereby maintaining high resolution with reduced device complexity
Solution Approach 2:
The pixel control circuits dynamically change their control targets between odd and even frames. Rather than being statically assigned to fixed pixels, the control circuits adaptively control different dot electrodes in different frames based on the interlaced scanning pattern. This dynamic reconfiguration enables efficient resource utilization and maintains high resolution with fewer control circuits
