Lighting Jig Signal Segmentation for TFT-LCD Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current lighting jigs for TFT-LCD panels are prone to damage and instability due to their complex structure, which complicates the input of drive signals, clock signals, and thin film transistor switch signals, leading to abnormal lighting issues.
Innovation Solution
A lighting jig with a signal generator, data signal circuit board, and scanning signal circuit board that split and input signals to the panel through separate probe pieces, improving signal stability by reducing alignment-dependent transmission failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple drive signals (data signal, clock signal, TFT switch signal) are input through a single access point, then the structure becomes integrated, but the structure becomes complicated and prone to damage
Solution Approach 1:
The patent divides the signal input system into separate access points: a data signal access point for data signals and a scanning signal access point for clock and TFT switch signals. This segmentation prevents the structural complexity and reliability issues caused by integrating multiple signal types through a single access point, while maintaining functional integration through the lighting jig's coordinated operation.
2Device complexity
If multiple functions are integrated into the access point for data signal, then signal transmission is simplified, but the access point becomes easy to damage
Solution Approach 1:
The patent separates the access point for data signal and the access point for scanning signal into distinct physical components. The data signal access point only handles data signals, while the scanning signal access point handles clock and TFT switch signals. This functional segmentation reduces the stress and complexity on each access point, making them more durable and less prone to damage.
3Ease of operation
If a single access point handles all signal functions, then connection is simplified, but abnormal lighting occurs due to damage
Solution Approach 1:
The patent implements separate access points for different signal types, with the data signal access point receiving data signals and the scanning signal access point receiving clock and TFT switch signals. This segmentation maintains operational simplicity through the lighting jig's automated coordination while ensuring reliable lighting operation by preventing the signal interference and damage issues that arise from multi-function integration in a single access point.
