VR Display Panel with Variable Sub-Pixel Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual reality systems, the high power consumption of display panels is exacerbated by the dense distribution of sub-pixels in peripheral display areas, which reduces clarity and increases energy usage.
Innovation Solution
A display panel design with a denser sub-pixel distribution in the central display area and a sparser distribution in surrounding areas, along with an image processing method that divides and renders images accordingly, to balance display quality and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If sub-pixels are evenly distributed across the entire display area, then the manufacturing process is simple and consistent, but the power consumption is high and the display quality in peripheral areas is reduced
Solution Approach 1:
The patent applies local quality by dividing the display area into a central region and peripheral regions, with each region having different sub-pixel densities. The central region maintains high sub-pixel density for high-definition display where the user's gaze is focused, while peripheral regions use lower sub-pixel density to reduce power consumption. This resolves the contradiction by making sub-pixel distribution non-uniform, sacrificing manufacturing simplicity for improved energy efficiency while maintaining display quality where needed.
2Manufacturing precision
If sub-pixels are densely distributed in the central display area, then the display quality in the gaze zone is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent segments the display area into distinct regions (central region and peripheral regions) with different sub-pixel distribution characteristics. This segmentation allows the central region to have high sub-pixel density for high-definition display quality, while peripheral regions have lower density. The segmentation resolves the contradiction by localizing high manufacturing precision requirements to only the central area, reducing overall device complexity compared to uniformly high-density distribution across the entire display.
3Area of stationary object
If sub-pixels are densely distributed in peripheral display areas, then the overall display coverage is maximized, but the power consumption increases and clarity is reduced
Solution Approach 1:
The patent applies local quality by implementing different sub-pixel densities in different spatial regions. The peripheral regions use lower sub-pixel density, which reduces the number of sub-pixels required and consequently reduces power consumption and energy loss. This resolves the contradiction by accepting reduced display detail in peripheral areas (lower sub-pixel density) to achieve significant energy savings, while maintaining full display area coverage.
