Spliced Display Bezel Identity Identification for Image Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in seamlessly splicing multiple display panels to maintain image integrity, often requiring cropping or scaling that can distort the display effect due to inadequate alignment and identification of bezel portions.
Innovation Solution
The implementation of a display panel bezel system with identifiable bezel portions that use identity identifiers and information transmission devices to determine splicing regions, allowing for precise segmentation of images across multiple panels without significant cropping or scaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple display panels are spliced together without identity identification, then the device structure is simple, but image alignment precision deteriorates causing distortion
Solution Approach 1:
The bezel is divided into multiple independent bezel portions, each with its own identity identifier. This segmentation allows each panel to be individually identified and positioned, enabling precise image alignment across multiple spliced panels while keeping each bezel portion structurally simple and easy to manufacture.
Solution Approach 2:
Identity identifiers are introduced as intermediary elements between the bezel portions and the control system. These identifiers act as mediators that enable the control system to recognize and differentiate between adjacent panels, facilitating precise image segmentation and alignment without requiring complex mechanical alignment mechanisms.
2Manufacturing precision
If identity identifiers and identification devices are added to bezel portions, then image segmentation precision is improved, but device complexity increases
Solution Approach 1:
The identity identifier and identification device are merged into the bezel portion structure itself, rather than being separate additional components. This integration allows the bezel to perform both its structural function and its identification function simultaneously, achieving precise splicing region alignment without proportionally increasing device complexity.
Solution Approach 2:
The bezel portion is designed to serve multiple functions: providing structural support for the display panel and simultaneously serving as a carrier for the identity identifier. This multi-functionality reduces the need for separate identification components, thereby limiting the increase in device complexity while maintaining high alignment precision.
3Ease of operation
If bezel portions are made detachable for easy assembly, then ease of operation is improved, but connection reliability may deteriorate
Solution Approach 1:
The bezel portions are pre-equipped with connection interfaces and identity identifiers during manufacturing. This preliminary preparation allows for quick and accurate assembly by simply connecting the pre-configured interfaces, while the pre-installed identity identifiers ensure that the connection maintains proper alignment and identification, thus preserving connection reliability.

AI summary
A display panel bezel, a display terminal, a spliced display device and an image output control method are provided. The display panel bezel includes at least two bezel portions forming an accommodating space for mounting a display panel, wherein each bezel portion includes an identity identifier and an identification device configured to identify the identity identifier and obtain at least one identity identifier of at least one bezel portion of the at least two bezel portions connected to the bezel portion.
