Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mirror displays experience a sense of disparity due to blanks generated between the content display area and the user reflection area, leading to an unsatisfactory user experience.
Innovation Solution
A display device with a mirror display comprising multiple blocks, a camera, and a processor that controls the reflectance and display of blocks to overlap the content with the mirror image, eliminating the blank area by adjusting reflectance levels and image processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If blocks are controlled in block units to display content and mirror image, then the display function is achieved, but blanks are generated between content and mirror image causing sense of disparity
Solution Approach 1:
The patent applies local quality by differentiating the reflectance control for blocks containing content boundaries versus other blocks. Specifically, when a block includes a content boundary, the processor controls it to have a higher reflectance than other blocks, enabling the mirror image to be displayed in the non-content area of such blocks. This local differentiation eliminates blanks between content and mirror image while maintaining the simplicity of block-unit control.
2Productivity
If reflectance is adjusted to eliminate blanks between content and mirror image, then display quality improves, but control complexity increases
Solution Approach 1:
The patent reduces control complexity by implementing a localized reflectance adjustment strategy. Instead of complex global optimization, the processor simply identifies blocks containing content boundaries and assigns them higher reflectance values, while other blocks use standard reflectance. This localized approach achieves blank elimination without requiring complex control algorithms.
Solution Approach 2:
The patent applies preliminary action by pre-identifying which blocks contain content boundaries before controlling their reflectance. The processor determines the content area first, then uses this information to selectively adjust reflectance of boundary-containing blocks. This preliminary identification simplifies the overall control process by avoiding real-time complex calculations.
3Productivity
If content size is adjusted to align with block boundaries, then visual coherence improves, but image processing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the display area into discrete blocks and aligning content boundaries with these block boundaries. The processor adjusts content size to ensure it fits within or aligns with the block grid structure. This segmentation approach simplifies the overall system by using the existing block architecture as the basis for content positioning, reducing the need for complex continuous positioning algorithms.
