Quincunx Video Streams for 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 high resolution video streams.
Innovation Solution
The implementation of configurable multi-electrode pixels with interlacing schemes, such as bob and quincunx interlacing, allows a single pixel control circuit to control different pixels in different frames, effectively increasing the resolution while reducing the number of required pixel control circuits, and the generation of quincunx video streams from high resolution video frames using smoothing filters and pixel blocks.

Engineering Contradiction Analysis
1Measurement precision
If conventional light modulating backplanes use standard pixel control circuits for each pixel, then the display resolution can be maintained, but the size of pixel control circuits increases leading to higher cost and power consumption
Solution Approach 1:
A single pixel control circuit is designed to control multiple different pixels across different frames through interlacing schemes. The circuit can be configured to control either even or odd pixels in different fields, making it a universal controller that replaces what would traditionally require separate dedicated circuits for each pixel location.
Solution Approach 2:
The pixel control circuit employs dynamic reconfiguration capabilities where the same circuit can be assigned to control different pixels depending on the field or frame being displayed. This dynamic switching allows the system to adapt the circuit-pixel mapping based on temporal requirements rather than maintaining fixed static assignments.
2Use of energy by stationary object
If the number of pixel control circuits is reduced through interlacing schemes, then power consumption decreases, but the effective resolution must be maintained through complex video stream generation
Solution Approach 1:
The system performs preliminary processing of video frames by generating quincunx video streams with pre-calculated pixel values before display. By pre-computing the pixel values using smoothing filters and pixel blocks, the system prepares the data in advance, reducing the real-time processing burden and enabling the use of fewer control circuits.
Solution Approach 2:
The invention creates derived video streams that are copies or transformations of the original high-resolution video. By generating quincunx video streams as derived copies with specific sampling patterns, the system enables efficient display on reduced circuitry while maintaining visual quality through the copying and transformation of pixel data.

AI summary
A method to generate a quincunx video stream is disclosed. The method includes generating a first-type quincunx field from a first high resolution video frame. The first-type quincunx field has a plurality quincunx pixels, each of which has an associated pixel in the first high resolution video frame. The quincunx pixels are calculated using a smoothing filter and a pixel block containing the associated pixels and other high resolution pixels near the associated pixels. A second-type quincunx field is generated from a second high resolution video frame.
