1、Concept

The RGB color mode is a color standard in the industry, which obtains a variety of colors through changes in the channels of three colors of red (R), green (G) and blue (B) and mutual superimposition among them. RGB represents the three channels of red, green and blue. This standard includes almost all the colors that human vision can perceive, and it is one of the most widely used color systems.
At present, most displays use the RGB color standard. On the display, colors are generated by shooting light emitters of the three colors of red, green and blue on the screen by electron guns. Currently, computers can generally display 32-bit colors, and there are more than 10 million types of colors.

2、Measuring Element

Measure the distance from the RGB border line to the panel edge on the LCD screen and the overall length and width of the RGB part.

3、Difficulty

1. As RGB is installed in the panel, it cannot achieve manual and contact measurement.
2. The light source of the ordinary projector or the imaging instrument cannot penetrate the panel, and clear imaging cannot be ensured if RGB is not lit.
3. As RGB imaging is relatively small, accurate measurement can be achieved under large magnification.

4、Solution

TZTEK VMS can be equipped with different typesof light sources to ensure that RGB can be clearly seen when the panel is not lit, and provide different magnification switching, so that its imaging effect can achieve relatively good measuring status and accuracy of measured data can be ensured.
It can automatically measure products in batches to meet efficient production needs.
