Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
LED matrix display screens have limitations in presenting stage visual effects, such as monotonous colors, inability to fit special shapes, and poor performance with special-shaped objects, due to fixed row-column alignment of pixel light sources, which restricts customization and flexibility in display.
Innovation Solution
A special-shaped LED display screen with independently controllable pixel point light sources arranged in a non-matrix array, using defined trend lines for scanning and control, and a control method that includes a storage unit and main control unit to handle image and video data, allowing for customization of shape, size, and dot matrix density based on the environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pixel point light sources are arranged in a fixed row-column matrix alignment manner, then the LED display screen structure is simple and easy to manufacture, but the display screen cannot fit special shapes and has monotonous visual effects
Solution Approach 1:
The patent divides the display screen into independent pixel point light sources that can be individually controlled and positioned. Each pixel is treated as an independent unit that can be arranged flexibly according to special shape requirements, breaking away from the fixed matrix structure while maintaining individual pixel controllability for simplified manufacturing processes.
Solution Approach 2:
The patent implements a dynamic control system that can adaptively adjust the arrangement and control of pixel point light sources based on different display requirements. The control method dynamically maps pixel positions to coordinate systems, enabling the same hardware structure to support both regular matrix arrangements and special-shaped configurations without physical reconfiguration.
2Adaptability or versatility
If pixel point light sources are arranged in a non-matrix array for special shape customization, then the display screen fits special shapes better and enriches visual effects, but the control and data reading complexity increases
Solution Approach 1:
The patent introduces a coordinate system mapping mechanism as an intermediary layer between the physical pixel arrangement and the control system. This mapping layer translates complex non-matrix pixel positions into manageable coordinate data, allowing the control system to handle special-shaped arrangements without direct complexity increase in the hardware control architecture.
Solution Approach 2:
The patent changes the control parameters from fixed matrix row-column addresses to dynamic coordinate-based addressing. By transforming the control parameter system to use coordinate mappings that adapt to different pixel arrangements, the control method can accommodate special shapes while maintaining a unified control interface that doesn't significantly increase system complexity.
3Adaptability or versatility
If pixel point light sources are arranged in a non-matrix array, then the display diversity and flexibility are enhanced, but the existing video signal processing capability becomes inapplicable
Solution Approach 1:
The patent adds a coordinate mapping dimension between the physical pixel arrangement and the video signal processing system. By introducing this intermediate coordinate transformation layer, the system can process standard video signals while adapting them to non-matrix pixel arrangements, maintaining compatibility with existing video processing capabilities while achieving enhanced display flexibility.

AI summary
A special-shaped display screen includes a carrier, and a plurality of pixel point light sources. The plurality of pixel point light sources are provided on the carrier, each of the pixel point light sources is controllable independently, and at least a portion of the pixel point light sources are arranged in a non-matrix array. A special-shaped pixel light includes a special-shaped display screen, a storage unit, and a main control unit. A control method of a special-shaped pixel light includes the following steps: S1, the main control unit establishing a mapping rule according to orientation characteristics of the pixel point light sources; S2, storing the mapping rule into the storage unit; and S3, receiving a control signal and invoking relevant data in the storage unit to scan the pixel point light sources according to the mapping rule.
