Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light-transmitting display regions are used to enable under-screen photosensitive components, then integration of cameras and sensors is improved, but diffraction phenomenon increases affecting photosensitive quality
Solution Approach 1:
The patent applies local quality by differentiating the pixel arrangement in the light-transmitting display region from other regions. Specifically, the pixel electrode arrangement, transparent conductive layer pattern, and organic light-emitting layer configuration are optimized locally in the light-transmitting area to reduce diffraction, while maintaining standard arrangements in non-light-transmitting areas. This localized optimization allows the light-transmitting region to serve dual purposes: enabling under-screen camera integration while minimizing diffraction effects that would degrade image quality.
Solution Approach 2:
The patent employs parameter changes by adjusting key structural parameters in the light-transmitting display region, including pixel electrode shape and size, transparent conductive layer thickness and pattern, and organic light-emitting layer composition. These parameter modifications are specifically tailored to reduce diffraction phenomenon while maintaining light transmission efficiency, thereby resolving the contradiction between enabling component integration and preventing harmful diffraction effects.
2Adaptability or versatility
If notches or holes are provided on display screens for light entry, then photosensitive components can be integrated under the screen, but display area is reduced and all-screen display is not achieved
Solution Approach 1:
The patent extracts the light transmission function from traditional notch or hole structures and integrates it directly into the display panel's light-transmitting display region. By removing the need for separate notches or holes and instead creating a region where pixels are configured to transmit light, the patent achieves under-screen camera integration while maintaining full display area coverage, thus resolving the contradiction between component integration and display area preservation.
Solution Approach 2:
The patent applies universality by making the light-transmitting display region perform multiple functions simultaneously: it serves as both a display area that can show images and a light transmission path for under-screen photosensitive components. This multi-functional design eliminates the need for dedicated notches or holes, allowing the entire screen surface to contribute to both display and sensor integration, thereby resolving the contradiction between integration capability and display area.
3Object-affected harmful factors
If pixel arrangement is optimized to reduce diffraction, then photosensitive quality improves, but device complexity increases
Solution Approach 1:
The patent reduces device complexity by applying local quality - the optimized pixel arrangement is implemented only in the light-transmitting display region where diffraction occurs, while standard pixel arrangements are maintained in non-light-transmitting areas. This localized approach minimizes the scope of structural modifications needed, thereby reducing overall device complexity while still achieving the goal of reducing diffraction phenomenon in the critical light transmission path.
