Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic display products are limited by their fixed design structures, resulting in low gray levels and difficulty in achieving high contrast display images.
Innovation Solution
A display device comprising a display panel and a light transmittance adjusting layer that adjusts brightness of pixel regions, allowing for increased gray levels and improved contrast through a light adjusting unit with micro-electro-mechanical driving, such as a rotating shaft and electrostatic micro-motors, to control light transmittance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed design structure is used for the display panel, then the device structure is simple and easy to manufacture, but the gray level is limited and contrast is low
Solution Approach 1:
The patent introduces a light adjusting unit with a light adjusting layer that can dynamically change its light adjusting state between first and second states. This dynamic adjustment capability allows the display device to achieve multiple gray levels (first gray level and second gray level) beyond the fixed limitations of the display panel structure, thereby improving contrast while maintaining manufacturing simplicity
Solution Approach 2:
The light adjusting layer changes its optical parameters by switching between different light adjusting states. When in the first state, it provides a first light transmittance corresponding to a first gray level; when in the second state, it provides a second light transmittance corresponding to a second gray level. This parameter change approach enables multi-gray-level display without requiring complex fixed structures
2Manufacturing precision
If the gray level is increased to improve contrast, then the display effect is improved, but the device structure becomes more complex
Solution Approach 1:
The patent segments the light adjustment function into a separate light adjusting unit that operates independently from the display panel. This segmentation allows the display panel to maintain its simple fixed structure while the light adjusting unit provides the additional gray level control, thereby achieving high contrast without significantly increasing overall device complexity
Solution Approach 2:
The light adjusting layer acts as an intermediary between the light source and the display panel. By placing this intermediate layer that can dynamically adjust light transmittance, the system achieves multiple gray levels without modifying the fundamental structure of the display panel, thus avoiding significant complexity increases
