Display Panel Middle Area Component Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels face limitations in increasing the screen-to-body ratio due to the arrangement of components like front cameras and receivers, which require non-display areas for signal lines, leading to a larger bezel size and hindering the achievement of a narrow bezel design.
Innovation Solution
The display panel incorporates a middle area between two subareas, allowing components to be positioned within the middle area, and uses separate driving circuits and signal lines for each subarea, ensuring they are insulated and do not occupy additional non-display areas, thereby reducing the bezel size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If front camera, receiver, or fingerprint recognition area are arranged in non-display areas, then these components can be properly positioned, but the screen-to-body ratio is limited and bezel size increases
Solution Approach 1:
The display panel is divided into a first subarea, a middle area, and a second subarea. The middle area is used to arrange components such as front camera, receiver, or fingerprint recognition area, while the first and second subareas are used for pixel display. This segmentation allows components to be positioned without occupying additional non-display areas, thereby improving screen-to-body ratio while maintaining component arrangement flexibility.
2Area of stationary object
If separate driving circuits and signal lines are used for each subarea, then signal lines are insulated and do not occupy additional non-display areas, but device complexity increases
Solution Approach 1:
The first driving circuit is integrated into the first subarea and the second driving circuit is integrated into the second subarea. Each driving circuit drives its corresponding driving signal lines within the same subarea. This merging of driving functions into respective subareas eliminates the need for additional non-display areas for signal line routing, reducing bezel size while managing complexity through functional integration.

AI summary
Disclosed are a display panel and a display device. A middle area is arranged between the first subarea and the second subarea so that components such as a camera and a receiver can be arranged at corresponding positions in the middle area. First driving signal lines only extend along the row direction of the pixels to the edge of the first subarea close to the middle area and second driving signal lines only extend to the edge of the second subarea close to the middle area. A first driving circuit is arranged in the first subarea to drive the first driving signal lines to operate and a second driving circuit is arranged in the second subarea to drive the second driving signal lines to operate.
