Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing one-sheet test devices are inadequate for testing substrates with varying numbers and sizes of panels, as they are designed for specific configurations, making it difficult to adapt and increasing manufacturing costs when panel variations occur.
Innovation Solution
A one-sheet test device comprising a signal supplier and connection board that generates multiple signal groups and dummy signals, allowing for flexible signal transmission to panels, including red, green, and blue data signals, gate signals, and power signals, with a connection controller to manage signal distribution based on the number of panels, enabling testing regardless of panel count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the test device is designed for specific panel configurations, then testing accuracy is improved, but adaptability deteriorates
Solution Approach 1:
The test device employs a universal test signal line that can be dynamically configured to connect to different numbers of panels (1-4 panels) through a switching mechanism. The connection board includes multiple switch elements that can be controlled to establish appropriate signal paths, allowing the same hardware to universally test various panel configurations without requiring separate dedicated test devices for each configuration.
Solution Approach 2:
The test device incorporates dynamic reconfigurability through controllable switch elements on the connection board. These switches can be dynamically adjusted based on the detected number of panels, transforming the static signal distribution into a dynamic adaptive system. The signal supplier and connection board work together to dynamically route test signals according to the actual panel configuration, enabling the device to adapt its testing capability in real-time.
2Adaptability or versatility
If the test device is redesigned for different panel configurations, then adaptability is improved, but manufacturing cost increases
Solution Approach 1:
Rather than manufacturing separate test devices for different panel configurations, the invention creates a single universal test device that can handle 1-4 panels through software-controlled switching. This eliminates the need for multiple specialized devices, reducing manufacturing costs while maintaining full adaptability. The connection board's switch elements provide a cost-effective mechanism to achieve multi-functionality without complex hardware redesigns.
Solution Approach 2:
The test device changes its operational parameters (signal routing configuration) based on the detected panel number rather than requiring physical redesign. By modifying the switching states of the connection board elements through control signals, the device adapts to different configurations parameter-wise, avoiding the cost of manufacturing multiple hardware variants while maintaining full adaptability.
3Adaptability or versatility
If multiple signal groups are generated for all possible panel configurations, then adaptability is improved, but device complexity increases
Solution Approach 1:
The test signal is segmented into multiple signal groups (first through fourth signal groups) that can be independently controlled and routed. The connection board divides the signal distribution into manageable segments, with each switch element controlling a specific signal path. This segmentation allows the complex task of adapting to 4 different panel configurations to be broken down into simpler, independently controllable switching decisions, reducing overall system complexity.
Solution Approach 2:
The connection board acts as an intermediary between the signal supplier and the panels, mediating the complex signal distribution task. Rather than the signal supplier directly managing all possible connections to all panel configurations, the connection board's switch elements serve as intermediate control points that simplify the routing logic. This intermediary structure reduces the complexity burden from the signal supplier and organizes the signal distribution into a more manageable hierarchical control system.

AI summary
A one-sheet test device for testing panels on a one-sheet substrate and a test method thereof, wherein the test device and method are capable of performing a one-sheet test regardless of the number of panels formed on the one-sheet substrate. The one-sheet test device includes a signal supplier and a connection board. The signal supplier is for generating a plurality of signal groups and a plurality of dummy signals for testing the panels. The connection board is for transmitting a first signal group of the signal groups to a first panel of the panels corresponding to the first signal group, and for transmitting a signal of at least one signal group of the plurality of signal groups to at least two of the panels when the number of panels is larger than the number signal groups. The one-sheet test device may include a connection controller for controlling the connection board.
