MD100N Display Measurement and Testing Solution


The Desktop-MD100N color and brightness inspection is considered as the Master in Display Test Systems and is an expert in capturing the high performance of contrast and color in display. It utilizes the advanced Optical spectral know-how and electronic signal processing technology replacing the Colormeter which has measurement inaccuracy problems. Also, MD100N spectroradiometer provides multi PC analysis softwares (uSpectrum/uFlicker) so users can customize the measuring list and analyze the big data simultaneously which simplifies workflow and speeds up work time.

LCD / OLED / microLED Display Test and measurement -MD100N measures the brightness and chroma value of the panel light easily and accurately that complies with the new display requirement. Key parameters include Luminance, CIE xy, Yxy, u’/v’, GAMMA correction and White Balance Adjustment with adequate speed and high precision. It’s precisely suitable for the display measurement of LCD, LED BLU, OLED, MiniLED, microLED that applies to smart phone, TV, Microdisplay, AR/VR ( Augmented Reality/ Virtual Reality) and even recommended wearable devices. Moreover, it can also be used in the panel production line.

UPRtek depends on our knowledgeable grating sensing and utilizes optimized measuring capabilities in display to provide the best color brightness measuring solution . It’s precisely the MD100N Desktop Spectroradiometer that realizes the demands and makes display industry interesting.


■What are the troblems form LCD (LED backlight) & OLED?

In the picture below,we can easily noticed that the radiation curve of these displays’ backlight are different. The main reason is each display has its own panel characteristic. Even a manufacturer produces the same batch of displays, it still has 5~10 nm offset at the peak wavelength which human eye cannot notice easily and it can lead to measurement error !



■Can panel characteristic errors cause chroma error?


Please refer to chart below. The wavelength has 1 nm offset and might lead to chroma error reaching to 0.0025. Imagine a panel characteristic causing a wavelength deviation from 5 to 10 nm, how much error do you think it can make?

The best choice is to use the display test solution-MD100N Desktop spectroradiometer to help you.


■What are the problems caused by differences in instrument capabilities?

Traditional Colormeter optical design uses RGB color filter sensor which simulates colors red, green and blue and estimates the color value which is close to spectral sensitivities of the human eye. However, the following disadvantages remain:

1) The value is not objective due to the following:

1st: The reflectance or transmittance rate is not included in the calculation.
2nd: There is no standard observer and perspective.
3rd : It calculates using RGB alone.

2) The processing of RGB color filter is difficult to control perfectly→The main reason is each RGB color filter sensor cannot perfectly match to CIE1931 XYZ color matching function.

Please refer the the table below. The wavelength shows error at ±2%→The maximum chroma error value is about 0.0066.


■What differences can you notice from the pictures below?

Due to the panel characteristics as described above, they will cause certain inevitable differences on displays, plus the limited capabilities of measuring instrument and inaccuracy from the measurement results, we obtained a non-incidental result from the picture below:

In the market, some existing measuring equipments have lower performance of measuring ability. So, they may not be able to effectively control and monitor display related products with quality issues. As a result, it leads to the worse coverage of quality and receives more complaints from end-users in the market.
