Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in integrating optical components like cameras within display panels without compromising the screen-to-body ratio, as they often require space for the camera, reducing the effective display area.
Innovation Solution
A display panel design with a primary and secondary display region, where the secondary region has higher light transmittance to accommodate an optical component, and pixel circuits are arranged in intersecting rows and columns with via holes for signal connections, allowing for both display and camera functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If an optical component such as a camera is placed in a region under a display panel, then the screen-to-body ratio is greatly increased, but the light transmittance of the display panel is reduced
Solution Approach 1:
The display panel is divided into a first display region with lower light transmittance and a second display region with higher light transmittance. The second display region, where the optical component is located, has optimized light transmission properties to accommodate the camera while the first display region maintains normal display characteristics. This local differentiation resolves the contradiction by allowing high light transmittance specifically where needed for the optical component.
2Measurement precision
If pixel circuits are arranged in a dense grid pattern, then the display resolution is improved, but the space available for optical components is reduced
Solution Approach 1:
The display panel is segmented into distinct functional regions: a first display region for high-resolution pixel circuits and a second display region with higher light transmittance for optical components. This segmentation allows the pixel circuits to be densely arranged in the first region to achieve high resolution while the second region provides dedicated space for the optical component without compromising display quality.
3Reliability
If the light transmittance of the secondary display region is increased to accommodate the optical component, then the optical component operates more effectively, but the display functionality in that region is compromised
Solution Approach 1:
The second display region is specifically designed with higher light transmittance properties to optimize optical component operation. The pixel circuits in this region are configured to work harmoniously with the enhanced light transmission, ensuring that both the optical component functionality and display capabilities are maintained without compromising either aspect.

AI summary
A display panel includes a primary display region and a secondary display region. A light transmittance of the primary display region is less than a light transmittance of the secondary display region. The display panel includes first pixel circuits located in the secondary display region. The first pixel circuits are arranged in rows and columns. The display panel includes a substrate, a first conductive layer and a first signal line layer. The first pixel circuits include conductive patterns located in the first conductive layer. The first signal line layer includes first-type signal lines extending in a first direction. A conductive pattern of each first pixel circuit located in a same row in the first direction is electrically connected to a first-type signal line through a first via hole, and the first via hole is located on a side of the first pixel circuit in the first direction.
