Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional spliced display panels suffer from a splice slit that cannot be displayed, leading to reduced display effect and a complex internal structure, which hinders further performance improvement.
Innovation Solution
A spliced display device with a light complement module covering the splice slit, comprising driver chips and light-emitting units on a driver board, ensuring consistent light emission and simplifying the internal structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple panels are spliced to form a large-size display panel, then the display size is increased, but a splice slit appears between adjacent panels causing display area loss
Solution Approach 1:
The patent converts the harmful splice slit (which causes display area loss) into a beneficial light-emitting region by placing light-emitting units in the splice slit area. The driver board extends into the splice slit region, and light-emitting units are arranged on the driver board to cover the splice slit, transforming the previously wasted space into a functional display area that compensates for the lost display region.
2Area of stationary object
If multiple panels are mechanically spliced to form a large-size display, then the display size is increased, but the internal structure becomes complex
Solution Approach 1:
The patent merges the driver boards of adjacent panels by extending the driver board into the splice slit region. This integration reduces the number of independent driver boards and simplifies the internal structure. The light-emitting units are directly mounted on the extended driver board, eliminating the need for separate driving mechanisms for the splice slit area and reducing overall structural complexity.
3Area of stationary object
If panels are spliced with mechanical connection, then large-size display is achieved, but maintenance becomes difficult
Solution Approach 1:
The patent maintains the modular structure of spliced panels while improving maintainability through the integrated driver board design. Each panel can still be independently replaced, but the extended driver board that spans across splice slits allows for centralized control and easier identification of faulty modules. The standardized interface and integrated driving circuitry simplify the replacement and maintenance process compared to fully independent mechanical splicing.
