To ensure the end-product quality is up to a high standard it is advisable to test displays at multiple stages during the production process.
Typical display tests include:
- Color analysis, to ensure uniformity of color reproduction of displays
- White point, adjusting white on displays in production settings
- Gamma, adjusting the tonal transfer curve of the display
- Flicker, testing and adjusting flicker supporting contrast min/max, contrast RMS, JEITA, VESA methods
- Response time to determine a display’s reaction speed
The table below gives an overview of different display measurements and corresponding measurement devices.

How are you measuring?
With fibers and other accessories even more type of measurements are possible. Often used accessories are integrating spheres, cuvettes for fluids, light sources or filter holders.
A cosine corrector collects the light from the half space under 180 degrees. A typical application is the illuminance measurement of a lighting situation.
Consumers are used to enjoy top-quality displays in their mobile phones, tablets, laptops and even cars. Emerging technologies such as lighting surfaces for office and home illumination are expected to look equally perfect. Both displays and luminous surfaces are the main application areas for imaging colorimeters.
Measuring the luminance or color values at a specific location of the device under test is a typical use case when measuring displays. It can, however, also be meaningful to assess reflected light.
