Projection Display Pixel-Density Adaptation Across Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The disparity in display specifications between source and destination devices in projection systems often leads to display failures or poor effects, negatively impacting user experience.
Innovation Solution
The method involves adjusting the display pixel density of the source device based on the destination device's specifications to optimize projection display, using a projection management module to store and apply the necessary pixel density adjustments for seamless adaptation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the source device projects content using its native display pixel density, then the display content is clear on the source device, but the display effect deteriorates on the destination device with different screen specifications
Solution Approach 1:
The patent dynamically changes the display pixel density parameter based on the destination device's screen specifications. The system obtains the destination device's pixel density, calculates a corresponding pixel density for the source device, and applies this adjusted parameter to achieve clear display adaptation across different devices.
2Adaptability or versatility
If the display pixel density is adjusted to adapt to the destination device, then the display effect on the destination device is improved, but the display effect on the source device may deteriorate
Solution Approach 1:
The system dynamically adjusts the display pixel density based on the projection state. When projecting to a destination device, the pixel density is changed to adapt to that device's specifications. When not projecting or when the projection is disconnected, the pixel density reverts to the original value, ensuring the source device's display remains clear.
3Adaptability or versatility
If the pixel density is dynamically adjusted during projection, then the display effect on the destination device is optimized, but the system complexity increases
Solution Approach 1:
The system automatically obtains the destination device's screen specifications, calculates the appropriate pixel density, and applies the adjustment without user intervention. The entire process is self-service, reducing the perceived complexity for users while achieving optimal display adaptation.
