Measuring display characterisation with imaging colorimeter and photometer
Instrument Systems (IS) offers a variety of instruments for display and light measurement. Here’s a breakdown of some of their key product lines and their applications:
1. Lumicam:
- Type: Camera-based imaging colorimeter
- Applications:
- Production line color quality control: Measures color uniformity across the entire display surface, ideal for identifying and analyzing inconsistencies in brightness, hue, and saturation.
- Display inspection: Detects defects like mura (cloud-like unevenness), mura spots, and dead pixels.
- Automated visual inspection: Can be integrated into production lines for fast and consistent quality control.
2. LumiTop:
- Type: Array spectrometer
- Applications:
- Display characterization: Measures the complete light spectrum emitted by a display, providing detailed information about color gamut, white point, and spectral power distribution.
- R&D and troubleshooting: Analyzes the spectral properties of displays for research and development or diagnosing complex color issues.
- Compliance testing: Ensures displays meet industry color standards (e.g., Rec. 709 for HDTV).
3. DMS (Display Measurement System):
- Type: Goniophotometer system (various models available)
- Applications:
- Advanced characterization of viewing angle dependence: Measures color, luminance, and contrast from various angles, crucial for displays with critical viewing angles (e.g., automotive displays, curved displays).
- Light distribution analysis: Analyzes the way light is emitted from a display, important for backlight evaluation and uniformity.
- HDR (High Dynamic Range) display characterization: Some DMS models can handle the high luminance ranges of HDR displays.
4. DTS (Digital Test Systems):
- Type: Integrated systems combining hardware and software for specific measurement tasks
- Applications:
- Automated testing solutions: Can be customized for specific display testing needs, incorporating instruments like LumiTop or Lumicam for comprehensive characterization.
- Flicker analysis: Measures and analyzes display flicker, which can cause eye strain.
- Touchscreen testing: Evaluates the performance and accuracy of touchscreens on displays.
In essence:
- Lumicam excels in production line quality control through color uniformity analysis and defect detection.
- LumiTop focuses on in-depth display characterization through spectral measurements.
- DMS tackles advanced characterization, especially for displays with critical viewing angles.
- DTS provides customized solutions for various display testing needs.
By choosing the right instrument(s) from IS’s range, DS Technology & Services Sdn Bhd can ensure their displays meet the highest quality standards across various production stages.

LUMITOP X150
LumiTop X150 imaging colorimeter is built with Ultra-high resolutions (151 megapixels), and complements the innovative 3-in-1 concept of our LumiTop test systems. It was developed in response to the growing challenges in display development and production of OLED or µLED displays in terms of subpixel quality.
LUMITOP 2700
LumiTop 2700 imaging colorimeters from Instrument Systems are used together with a CAS spectroradiometer for measuring the luminance and color uniformity of displays in the production line. LumiTop 2700 camera has 6 megapixels resolution RGB sensor (CCD)
LUMITOP 4000
LumiTop 4000 as an advancement of the LumiTop 2700 can detect and analyze even smaller defects and inhomogeneities, and in combination with the 100 mm lens it permits single pixel analyses (limited field of view). The high-luminance mode extends the dynamic range, particularly with modulated displays and light sources (such as OLED displays).
