Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional opaque liquid crystal displays are used, then manufacturing and assembly are straightforward, but visual impact and transparency effect are insufficient
Solution Approach 1:
The display panel is segmented into multiple pixel units, where each pixel unit contains transparent pixel units interspersed among colored pixel units. This segmentation allows light to pass through specific regions, creating a transparent visual effect while maintaining the display function in other areas.
Solution Approach 2:
Different regions of the display panel have different optical properties. The transparent pixel units have high light transmittance for transparency effect, while colored pixel units have specific color filtering properties. The black matrix regions provide light blocking. This local differentiation of optical qualities enables both transparency and display functionality.
2Illumination intensity
If transparent pixel units are added to the color filter substrate, then transparency effect is improved, but manufacturing precision requirements increase
Solution Approach 1:
The transparent pixel units are integrated into the color filter substrate along with the colored pixel units, forming a unified pixel array. The black matrix serves as a common structural element that defines boundaries for both transparent and colored pixel units, providing alignment references that simplify manufacturing precision requirements.
Solution Approach 2:
The black matrix acts as an intermediary structure that separates and defines both colored and transparent pixel units. By using the black matrix as a reference framework, the positioning and alignment of transparent pixel units can be controlled more easily during manufacturing, reducing precision requirements.
3Illumination intensity
If transparent regions are created in the backlight module and TFT array substrate, then transparency effect is enhanced, but device complexity increases
Solution Approach 1:
The backlight module is segmented into regions corresponding to transparent pixel units and colored pixel units. The transparent regions in the backlight module allow light to pass through directly, while other regions contain backlight assemblies. This segmentation enables selective light transmission to match the pixel unit arrangement above.
Solution Approach 2:
Backlight assemblies are extracted from regions corresponding to transparent pixel units, creating transparent windows in the backlight module. This removal of components in specific areas allows light to pass through the entire stack without obstruction, achieving the transparency effect while maintaining backlight functionality in other areas.
