Display Drive Method for Naked-Eye 3D Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Naked-eye 3D display technology faces a significant reduction in pixels per inch (PPI) due to light-blocking grating designs, resulting in reduced 3D effects and limited resolution enhancement, as sub-pixel size cannot be infinitely minimized.
Innovation Solution
A display driving method that calculates the proportion of each physical pixel unit overlapping a sampling region to determine the output signal of sub-pixels, allowing for enhanced resolution and display effects without increasing pixel size, by obtaining and processing input signals based on overlapping areas within rectangular sampling regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the size of sub-pixels is reduced to improve resolution, then the resolution of the display device is improved, but it becomes impossible to infinitely reduce the sub-pixel size due to technical limitations
Solution Approach 1:
The patent transitions from spatial dimension (reducing sub-pixel size) to temporal dimension (using multiple sampling points in time) to achieve higher resolution. By sampling at different time points and combining the information, the system effectively increases resolution without further reducing physical sub-pixel dimensions.
Solution Approach 2:
The patent divides a single pixel's information into multiple sampling points within the pixel time period. Each sampling point captures partial information, and through calculation combining multiple sampling results, the complete high-resolution information is reconstructed, effectively segmenting the information gathering process.
2Adaptability or versatility
If a light-blocking grating design is adopted for naked-eye 3D display, then 3D visual effects are achieved, but the pixels per inch (PPI) is significantly reduced by up to 50%
Solution Approach 1:
The patent merges information from multiple sampling points within the same pixel time period to compensate for the resolution loss caused by the grating structure. By combining multiple lower-resolution samples taken at different times, the system reconstructs a higher-resolution image that overcomes the PPI reduction from the grating design.
Solution Approach 2:
The patent performs multiple preliminary sampling actions within each pixel time period before the final image is displayed. These preliminary samples are taken at different time points and positions, and through calculation they are combined to produce the final high-resolution output, preparing the data in advance to overcome the grating's resolution limitation.
3Manufacturing precision
If multiple sampling points are set within the same pixel time period, then the resolution is enhanced without increasing pixel size, but the calculation complexity increases
Solution Approach 1:
The patent changes the temporal parameter by introducing multiple sampling points within the pixel time period. Instead of a single spatial sample, multiple temporal samples are taken and combined through calculation. This parameter change from single-point to multi-point sampling enhances resolution while the calculation complexity is managed through systematic processing of the additional data points.
