Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a transmission area is provided in the component area to allow light transmission, then light transmission is enabled, but display elements cannot be arranged in that area
Solution Approach 1:
The component area is segmented into multiple transmission areas and non-transmission areas, allowing different regions to serve different functions. Transmission areas enable light transmission for component operation, while non-transmission areas maintain display functionality, thus resolving the contradiction between light transmission and display area coverage.
Solution Approach 2:
Different regions of the component area are assigned different optical properties: transmission areas have high light transmittance for component operation, while non-transmission areas have display elements arranged for image display. This local differentiation allows both light transmission and display area requirements to be satisfied simultaneously.
2Area of stationary object
If display elements are arranged in the component area to extend display area, then display area is increased, but electronic components cannot be accommodated
Solution Approach 1:
The component area is divided into transmission areas (for component placement) and non-transmission areas (for display elements), enabling both electronic components and display elements to coexist in the same physical space without interfering with each other's functionality.
Solution Approach 2:
The component area serves dual functions: it accommodates electronic components in transmission areas while simultaneously providing display area through non-transmission areas. This multi-functionality resolves the contradiction between component accommodation and display area extension.
3Area of stationary object
If multiple pixel circuits are disposed in the component area, then display functionality is extended, but device complexity increases
Solution Approach 1:
Pixel circuits are selectively arranged only in non-transmission areas of the component area, while transmission areas remain free for component placement. This localized arrangement extends display area without requiring complex pixel circuit integration across the entire component area, thus managing device complexity effectively.

AI summary
A display panel includes a main display area, and a component area including a transmission area. The display panel includes a substrate including a groove disposed in the transmission area in a depth direction of the substrate; main display elements disposed above the substrate in the main display area; main pixel circuits electrically connected to the main display elements; and auxiliary display elements disposed above the substrate in the component area; and auxiliary pixel circuits electrically connected to the auxiliary display elements.
