Introduction

Companies that manufacture, buy and sell display panels face a similar problem.  And that is the need for efficiently measuring Display Panel performance in various situations, like on production lines, R&D test labs, FAE offsite locations.

The choices are few. Use a Colorimeter that is portable but inaccurate or you can use laboratory-level equipment, which is accurate but slow, bulky and expensive.

With the MK550T handheld spectroradiometer, anyone has access to cost-effective, lab-level instrumentation that can measure more than10x faster than other precision instrumentation.

The MK550T is used in manufacturing R&D development. It is used on production lines interfacing with manufacturing production equipment.  It is used by Field Application Engineers for remote site OEM/ODM work.

MK550T – Boost versatility & flexibility in measurement capabilities through portable, fast performance.

    • Laboratory-Level precision – Diffraction Grating and proprietary technologies
    • Different receptor sizes (for small size displays – e.g. watches)
    • SDK allows manufacturers to integrate with their own RD efforts
    • Supports several 3rd party tuning tools
    • JEITA, Contrast, VESA, RMS, FFT Flicker metrics
    • Handheld versatility and can also mount on a stand, cable connect to PC for hands free operations.

Lab-Research level precision – Diffraction Grating

A 3-color sensor RGB colorimeter can perform  tasks to evaluate Display Panels but with significant room for error. Most Display Manufacturers find this unacceptable.

The MK550T uses a diffraction grating that is more accurate and discerning when distinguishing colors.

Infused with years of development effort in proprietary technologies, UPRtek delivers lab-level measurement accuracy that is being actively used in production lines of various Display Panel manufacturers.

UPRtek Diffraction Grating Technology vs RGB Colorimeter

Inaccuracies using 3-color RGB Colorimeter

MK550T has several receptor size options

(Ø10mm, Ø5mm, Ø2mm)

The MK550T comes in several receptor size models for large displays (display panels) and small displays (e.g. watches, cell phones).

Ensuring measurement accuracy

Measurement devices also have to abide by globally accepted standards.  This also helps to ensure optimal accuracy, accepted by the industry community. 

The MKT550 supports several 3rd party tuning tools to boost display performance accuracy: CalMan, UPRtek XYZ Matrix Calibration, Wavelength Shift Calibration Tool, Spectral Intensity Calibration Tool.

Additionally, MK550T provides SDK facilities to integrate with companies using their own RD software/hardware support.

Evaluating Flicker

MK550T can evaluate flicker for Display Panels with different metrics from globally recognized standards organizations.
