Notched Display Panel Edge Design for Screen Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designing irregularly shaped display panels with improved performance is challenging due to the need to accommodate devices like cameras and maintain screen ratio and display brightness, especially as the irregularly shaped regions become larger, making it difficult to form large-sized panels with uniform performance.
Innovation Solution
A display panel design featuring a display region with notches to accommodate devices, where the first edge is recessed to form a notch, allowing for a denser line arrangement and reducing the influence on display performance, with light-emitting control lines and scanning drivers configured to maintain signal transmission and control across the panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display panel is designed with irregular shape to accommodate function modules, then the screen ratio is improved, but the manufacturing precision deteriorates
Solution Approach 1:
The patent applies local quality by making the first edge recessed to form a notch, creating a non-uniform local structure that accommodates function modules while maintaining uniform line arrangement in other regions. This localized modification allows the display panel to achieve both high screen ratio and manufacturing precision by concentrating the irregularity only where necessary.
2Area of stationary object
If the irregularly shaped region is enlarged to improve screen ratio, then the display performance deteriorates
Solution Approach 1:
The patent uses local quality by confining the irregular shape to a specific local region (the notch on the first edge) rather than making the entire display panel irregular. This allows the majority of the display region to maintain uniform characteristics, ensuring consistent display brightness and performance while still achieving high screen ratio through the localized notch structure.
Solution Approach 2:
The patent applies segmentation by dividing the display panel into distinct regions: a regular display region with uniform performance characteristics and a notch region that accommodates function modules. This segmentation allows the main display area to maintain uniform brightness and performance while the notch area handles the irregular shape requirements, thus resolving the contradiction between screen ratio and display quality.
3Area of stationary object
If the first edge is recessed to form notch, then the screen ratio is improved, but the device complexity increases
Solution Approach 1:
The patent applies local quality by implementing the notch structure only on the first edge where it is most effective, while keeping other edges and regions simple and regular. This localized approach to creating the irregular shape minimizes the impact on overall device complexity while still achieving the goal of improved screen ratio, as the line arrangement complexity is confined to a small local area rather than affecting the entire panel.

AI summary
A display panel and a display device are provided. The display panel includes a display region; a non-display region; and at least one notch. The display region includes a first edge, a plurality of data lines, a plurality of scanning lines, and a plurality of light-emitting control lines. The plurality of data lines and the first edge extend along a column direction. The first edge is recessed toward the display region to form the at least one notch. The plurality of light-emitting control lines includes first light-emitting control lines and second light-emitting control lines. The non-display region includes a plurality of first light-emitting controllers in a cascade configuration disposed at one side of the first light-emitting control lines away from the at least one notch. An output terminal of each of the plurality of first light-emitting controllers is electrically connected to at least one of the first light-emitting control lines.
