Display Panel Drive Circuit Grouping for Fingerprint Aperture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices with fingerprint recognition functions face challenges in efficiently configuring imaging apertures due to the compression of drive circuits, which can lead to uneven display effects and reduced light-emitting areas of organic light-emitting units.
Innovation Solution
A display panel design where drive circuits are divided into groups with adjusted spacing, allowing imaging apertures between adjacent groups, and vias are oriented to minimize area reduction and misalignment, ensuring even distribution of opening region reductions and maintaining desirable display effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If drive circuits are compressed to increase imaging aperture space, then space for imaging apertures is improved, but light-emitting areas of organic light-emitting units are reduced
Solution Approach 1:
The drive circuits are divided into multiple drive circuit groups arranged in a matrix, with imaging apertures positioned between adjacent groups. This segmentation allows the drive circuits to be compressed within groups while maintaining spacing between groups for imaging apertures, thus resolving the contradiction between compressing drive circuits and preserving light-emitting areas.
2Adaptability or versatility
If drive circuits are compressed to configure imaging apertures, then imaging aperture configuration is improved, but display uniformity deteriorates
Solution Approach 1:
The patent applies different spacing strategies to different regions: drive circuits within the same group are compressed to create space for imaging apertures, while drive circuits in adjacent groups maintain appropriate spacing. This local differentiation allows imaging aperture configuration while preserving display uniformity through controlled compression only where necessary.
3Area of stationary object
If drive circuits are arranged densely to improve space utilization, then space utilization is improved, but via alignment precision deteriorates
Solution Approach 1:
By segmenting drive circuits into groups with internal compression and external spacing, the patent creates distinct regions where via alignment can be precisely controlled within groups while maintaining overall space utilization efficiency through the compact group arrangement.

AI summary
Display panel and display device are provided. The display panel includes fingerprint recognition units, a substrate, drive circuits, and organic light-emitting units. A distance between two adjacent drive circuits in each drive circuit group is less than a distance between two adjacent drive circuits in two adjacent drive circuit groups along a first direction. The drive circuits from a first row to an i-th row is a first drive circuit, and the drive circuits from a j-th row to an M-th row is a second drive circuit. A first direction component, along the first direction, of each of vias that correspond to at least a portion of the first drive circuit pointing to a first corresponding electrically-connected anode, and a second direction component, along the first direction, of each of vias that correspond to at least a portion of the second drive circuit pointing to a second corresponding electrically-connected anode, are opposite components.
