MK550T Display Measurement and Testing Solution

MK550T Handheld Spectroradiometer combines the advanced Optical spectral know-how and electronic signal processing technology to make the whole measuring system becomes faster and more accurate than common expensive instruments, and it is used in production line of display modules for global smart phone like what other Colormeters do. Excellent accuracy proformance from high brightness to low brightness helps to guard better color performance and image quality for display. It is perfect for OLED display to meet the inspection and adjustment requirement of GAMMA Correction.
MK550T spectroradiometer is lightweight, portable, with 3.5 UI colored touchscreen and stand-alone which means it can be operated without computer connection. At the same time, MK550T luminance meter is suitable for various display measurements of LCD, LED, BLU, OLED, MiniLED, microLED that are applied to smart phone, TV, Microdisplay, AR/VR ( Augmented Reality/ Virtual Reality) products and even recommended wearable devices.
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 MK550T 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?
Ans:Yes
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-MK550T 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.
Enhance your display test and measuring capacities, MK550T Photometric Brightness Measurement will be your best help!
Features:
■High accurate measurement performance
Make sure that the spectral sensitivities of x (λ) / y (λ) / z (λ) are comparable to the CIE1931 color matching function. Easily enhance the chroma accuracy and provide measurements result which closer to the human visual function.
■MK550T is the best assistant for improving display technology and display quality
The advanced spectral technology provides customers with better chroma accuracy and chroma reproducibility. It also fully supports the GAMMA correction task from high to low luminance range precisely for most display products. MK550 Spectroradiometer helps customers achieve success and deliver the most realistic visual experience of new display.
■Providing wide-range sensor options for various needs
Offer different options of receptor sizes to users. It fulfills the measuring requirement of next generation of display: OLED display on the consumer electronic products, display on AR/VR products and even wearable devices.
Availabe Receptor Size: Φ 10mm / Φ 5mmΦ 4mm / Φ 3mm
■One-stop Design
Connectiion to an additioanl heavy data analyzer or external sensor is unnecessary and inconvenient. MK550T is the innovative measuring solution that integrates multiple equipments into a portable device perfectly. What you see is waht you get. The real-time measurement data can be obtained rapidly under a standalone operation.
■Key measuring paremeters:
(1) Luminance Measuring Range: 0.001 ~ 5,000 cd/m-2
(2) Luminance Accuracy : +/- 3% @ 0.2~100 cd/m-2
(3) Color (x/y) : Accuracy +/- 0.003 @ 0.2 ~ 100 cd/m-2
(4) Flicker : JEITA / VESA / CONTRAST (Max/Min),RMS, Time Domain, FFT
(5) Spectrum : Visible spectral data / graphic
