Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a transparent display device is designed to allow light transmission, then light transmittance is improved, but image quality and functionality deteriorate

Engineering Contradiction:

Improvelight transmittanceVSAvoidimage quality

Core Design Contradiction:

Illumination intensityVSReliability

Solution Approach 1:

The pixel structure is divided into multiple functional areas: sub-pixel area for light emission, window area for light transmission, pixel circuit area for electrical control, and light transmission area for additional optical path. This segmentation allows each area to optimize its specific function while contributing to overall transparency and image quality

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different regions of the display device are assigned different properties: the window area and light transmission area are optimized for light transmission with minimal obstacles, while the pixel circuit area contains necessary electrical components. This local differentiation enables simultaneous achievement of high transparency and functional reliability

Inventive Principle:

Principle #3Local quality

2Adaptability or versatility

If the pixel circuit area is expanded to include all necessary transistors and capacitors, then functionality is improved, but light transmittance deteriorates

Engineering Contradiction:

Solution Approach 1:

The pixel structure is divided into multiple functional areas: sub-pixel area for light emission, window area for light transmission, pixel circuit area for electrical control, and light transmission area for additional optical path. This segmentation allows each area to optimize its specific function while contributing to overall transparency and image quality

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The pixel circuit area is repositioned to the side of the light emission area rather than occupying the central emission region. By moving the circuit components to a lateral dimension, the design maintains all necessary electrical functionality while preserving the central area for optimal light transmission and image display
