Display Panel Detection Device Using Segmented Shorting Bars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional detection devices fail to perform pure color detection on both RGB and RGBW display panels, as they are designed to detect only totally bright images and not individual red, green, and blue images separately.
Innovation Solution
A detection device with twelve signal source input terminals and corresponding shorting bars is designed, where each shorting bar connects to specific data lines on the display panel, allowing for input of detection signals to all pixels for bright images and specific pixel units for pure color detection, enabling the detection of diverse colors on both RGB and RGBW panels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional detection device with three shorting bars is used for RGB display panels, then the device can detect totally bright images, but it fails to detect individual red, green, and blue images separately
Solution Approach 1:
The detection device divides the detection function into separate channels by providing independent shorting bars for each color (red, green, blue, and white). Each shorting bar can be independently controlled to connect to specific pixel units, enabling separate detection of each color without interference from other colors. This segmentation allows the device to detect pure color images while maintaining the ability to detect bright images.
2Measurement precision
If a detection device with four shorting bars is used for RGBW display panels, then the device can detect totally bright images, but it fails to detect individual red, green, and blue images separately
Solution Approach 1:
The detection device segments the detection function by providing independent shorting bars for each color (red, green, blue, and white). Each shorting bar is independently controllable and connects to specific pixel units, enabling separate detection of each color. This allows the device to detect pure color images while maintaining bright image detection capability.
3Adaptability or versatility
If the same detection device is used for both RGB and RGBW display panels, then device versatility is maintained, but pure color detection cannot be performed on either panel type
Solution Approach 1:
The detection device achieves universality by incorporating four shorting bars that can detect all four color types (red, green, blue, and white). This configuration allows the same device to handle both RGB and RGBW display panels effectively. The device can detect totally bright images on any panel type while also being capable of detecting individual pure color images on RGBW panels and combining color detection on RGB panels.
4Ease of manufacture
If conventional detection devices are used, then device simplicity is maintained, but accurate image evaluation cannot be performed
Solution Approach 1:
The detection device segments the detection function into independent color channels with separate shorting bars for red, green, blue, and white. This segmentation enables accurate detection of pure color images while maintaining the ability to detect bright images. The independent control of each shorting bar allows precise evaluation of color accuracy and brightness without interference, achieving both simplicity and precision.

AI summary
The present disclosure proposes a detection device for a display panel. The detection device includes twelve signal source input terminals for inputting a detection signal, and twelve shorting bars corresponding to the signal source input terminals one on one. One end of the shorting bar is connected to the corresponding signal source input terminal, and the other end of the shorting bar is connected to a corresponding data line on the display panel.
