MD100N Desktop Spectroradiometer

Cost effective display panel evaluation on production lines

Laboratory-level spectroradiometers are not feasible to use in production facilities – they are expensive, bulky and slow to measure.  The MD100N Spectroradiometer addresses those issues with cost-effective,  adaptable, flexible design with a high focus on accuracy/precision.

Introduction

Display Panel manufacturers know that it’s troublesome to maintain image quality consistency in their panels,  from product to product, batch to batch.

Additionally, there has been an influx of new display technologies and all the quality issues that ensue (Lv, color accuracy, contrast, gamma, metamerism, visual eye safety etc).

These manufacturers have laboratory-level light measurement instrumentation to address these inconsistencies, but they are often cost-prohibitive, bulky and painfully time-consuming to be used on production lines.

The MD100N is a spectroradiometer that is cost-effective, with fast measurement times, and a focus on Laboratory-level precision.  It can be used by manufacturers, OEM/ODM companies of any size and allows much more flexibility and versatility in Quality Control.

MD100N is used with laptop/PC running the uSpectrum or uFlicker software.

MD100N Desktop Spectroradiometer 

  • Diffraction grating can differentiate spectrum colors to 1nm intervals
  • Full Flicker metrics (JEITA, CONTRAST, VESA, RMS, FFT)
  • SDK interface allow own RD efforts to integrate with MD100N data.
  • MD100N must be used with accompanying PC/Laptop. USB  or RS232 cable connection.
  • Different receptor sizes for smaller displays (e.g. watches).
  • Supported by XYZ Matrix Calibration and Calman Studios

The Difference – Diffraction Grating

It’s possible to use a simple 3-color RGB colorimeter to evaluate panels.  Of course, there is a lot of room for error and deviations in measurement.

UPRtek spectroradiometers employ diffraction grating at 1nm intervals, which means over 400 distinguishable colors.  The measurement time is 10x faster than other laboratory-level equipment.

Laboratory-level precision and accuracy

Inaccuracies from simple RGB colorimeters – wavelength shift

Crushing Display Panel Flicker

Display panel flicker is another problem in non-LCD panels.  UPRtek provides metrics for the most commonly used standards to check flicker.

JEITA – Japanese Electronics and Information Technology (Japan)

VESA – Video Electronics Standards Association (USA)

CONTRAST  – calculated flicker ratio

RMS – calculated Root Mean Square of voltage variations

FFT – Fast Fourier Transform

The need for consistency & accuracy

Calibration Standards – Calman, XYZ Matrix Calibration

UPRtek spectroradiometers are supported by world leading calibration standards including Calman Studio and XYZ Matrix Calibration software.

SDK (Software Development Kit) support

The MD100N also offers SDK interface support to integrate with RD software efforts implemented by manufacturers.

MD100N and MK550T supported by Calman Studios

Display panels – all types and sizes

The proliferation and evolution of display panels (LED, OLED, HDR, wider gamut displays, mobile devices, wearable devices, AR/VR) has made it even more important to use convenient, versatile measuring instruments.

MD100N  has different receptor sizes to adapt to most screen sizes.

Full Screen View & Data Analytics

The MD100N is used with uSpectrum and uFlicker software, both of which are easily downloaded to a laptop/PC (free of charge).  They allow you to Operate the MD100N easily and display configurable data sets as you prefer.
