Display Panel Pixel Layout With Shared Backup Emitters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Self-light-emitting display panels require a large number of backup light-emitting elements to maintain display effectiveness, increasing manufacturing costs and arrangement space due to the need for each light-emitting element to have a corresponding backup.
Innovation Solution
A display panel design where the number of main light-emitting elements exceeds the number of backup light-emitting elements, with backup elements strategically placed between main elements to ensure display continuity, reducing the overall number of backup elements required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each light-emitting element is configured with a backup light-emitting element, then the display reliability is improved, but the number of light-emitting elements increases and the manufacturing cost increases
Solution Approach 1:
Multiple main light-emitting elements are merged to share common backup light-emitting elements. Instead of assigning dedicated backups to each main element, the patent configures backup elements that can serve multiple main elements simultaneously, reducing the total quantity while maintaining reliability coverage.
Solution Approach 2:
The backup light-emitting elements are designed with multi-functionality to replace different main light-emitting elements based on failure patterns. A single backup element can serve multiple main elements in different spatial locations, making the backup system universal rather than dedicated to specific elements.
2Reliability
If each light-emitting element is configured with a backup light-emitting element, then the display reliability is improved, but the arrangement space increases
Solution Approach 1:
The patent merges the backup functions for multiple main light-emitting elements into shared backup elements, thereby consolidating the space required for backups. This reduces the total arrangement space while maintaining the ability to replace failed main elements.
Solution Approach 2:
The patent arranges main and backup light-emitting elements in a specific spatial pattern where backup elements are positioned to serve multiple main elements across different dimensions. This dimensional arrangement optimizes space utilization by allowing one backup element to cover multiple main elements in a two-dimensional layout.
3Measurement precision
If a large number of light-emitting elements are disposed, then the display resolution is improved, but the preparation cost increases
Solution Approach 1:
The patent merges backup functions across multiple main light-emitting elements, reducing the total number of elements that need to be prepared and assembled. This lowers preparation cost while maintaining the high resolution achieved through the dense arrangement of main elements.
Solution Approach 2:
Instead of creating dedicated backup copies for each main element, the patent uses shared backup elements that can function as replacements for multiple main elements. This reduces the copying overhead and preparation cost associated with having individual backups for each high-resolution pixel.

AI summary
Provided are a display panel and a display device. The display panel includes a substrate and multiple display units located on a side of the substrate. The display units include multiple light-emitting elements. The light-emitting elements include main light-emitting elements and backup light-emitting elements. The number of main light-emitting elements is greater than the number of backup light-emitting elements. The main light-emitting elements are arranged in a first direction. In a second direction, a backup light-emitting element is located between two main light-emitting elements. In the second direction, at least two main light-emitting elements are disposed adjacent to each other. When the display panel is driven to display an image, and when a dead pixel appears in a main light-emitting element, a backup light-emitting element emits light to replace the main light-emitting element in which the dead pixel appears for display.
