A display panel design with a high light transmittance first area for integrating photosensitive assemblies and a transition area with divided sub-areas for pixel circuit units, reducing wiring complexity and increasing pixel density.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a notch or hole is formed in the display screen to integrate front camera and sensors, then photosensitive assembly integration is achieved, but the display area is reduced and full-screen display cannot be achieved
Solution Approach 1:
The display screen is segmented into a first display area with higher light transmittance and a second display area with lower light transmittance. The first display area is specifically designed to allow light passage for under-screen camera integration, while maintaining display functionality. This segmentation enables the front camera to be integrated beneath the screen without requiring a physical notch or hole, thereby preserving the full-screen display area while achieving photosensitive assembly integration.
2Quantity of substance
If pixel circuit units are placed in the first display area to drive pixel units, then pixel density is improved, but light transmittance is reduced and wiring complexity increases
Solution Approach 1:
The pixel circuit units are moved from the traditional planar arrangement within the first display area to a three-dimensional structure located in the gap between the substrate and the pixel electrode. This vertical placement in the Z-dimension allows the pixel circuits to be positioned without occupying horizontal display area, thereby maintaining high light transmittance in the first display area while still providing driving capability for high pixel density.
3Illumination intensity
If pixel circuit units are placed in the transition display area, then light transmittance of the first display area is improved, but wiring distance increases and wiring complexity increases
Solution Approach 1:
The transition display area is divided into multiple sub-areas, with each sub-area containing pixel circuit units specifically positioned to serve adjacent pixel units in the first display area. This localized arrangement ensures that while pixel circuits are outside the first display area, they are optimally positioned to minimize wiring distance and maintain efficient electrical connections, thereby reducing wiring complexity despite the spatial separation.
4Quantity of substance
If the transition display area is divided into sub-areas with pixel circuit units, then wiring space is optimized and pixel density is improved, but device complexity increases
Solution Approach 1:
The transition display area is divided into multiple sub-areas, with each sub-area containing pixel circuit units positioned to serve specific pixel units. This segmentation creates a modular structure that optimizes wiring space by organizing circuits in discrete functional units, thereby enabling higher pixel density while managing device complexity through systematic division rather than random arrangement.
