Farewell to point spectrometers and RGB cameras in display and light source inspection

31 Jan 2022

WHY DOES SPECIM FX10 OUTPERFORM POINT SPECTROMETERS AND RGB CAMERAS?

FX10 works as a high-speed imaging spectroradiometer.

Most current display panels and light sources are based on LED backlights. They produce inconsistent spectra and therefore their accurate colour measurement is only possible by measuring the actual spectrum. Traditionally it is done by point spectrophotometers, which in production, limit the inspection to a few discrete points on the display surface, because of limited inspection time.

The challenge with current imaging photometers is, that they are based on RGB tricolour cameras. They suffer from limited colour gamut and measurement accuracy, as the broad band RGB filter responses do not match standard colour coordinates XYZ.

An advanced imaging solution is needed for rapid and accurate inspection of the entire surface.

SPECIM FX10 is the first camera on the market which can measure the spectral radiance image of entire display fast enough for quality inspection in production and assembly lines. Spectral data provides most accurate colorimetric and luminance values for the entire DUT surface for both narrow and broadband sources characterising display colour gamut, luminance level and uniformity.

SPECIM FX10 makes it possible to measure simultaneously in both visual and near infrared region (400-1000 nm) facilitating testing of systems like virtual reality solutions, that use LEDs in the 800-900 nm region.

Working as an on-line imaging spectroradiometer, SPECIM FX10 allows 100% inspection at production, minimising rework and complaints in later phases. As FX10 collects real spectral data from entire product flow, it enables analysing production quality statistics, and in case of issues, helps to find the root causes.
