GS-1164 4-Angle Display Color Spectroradiometer

The new GS-1164 4-angle spectroradiometer measures display color and luminance simultaneously at 0, 30, 45 and 60 degrees. The platform’s cutting edge spectrometer technology is superior to filter based colorimeters as it is not affected by filter matching errors. This technology delivers true spectral based measurement accuracy that is required for the higher color saturation and wider color gamut of OLED displays.


The GS-1164 is capable of accurate and repeatable measurements at speeds of more than 10X the speed of existing, status-quo spectrometers. This enables high throughput production testing with no tradeoffs in measurement accuracy or repeatability.

*1    Input source must be a stable light source
*2    Measure in normal mode with temperature 23±2 °C and relative humidity 50% or less
*3    Repeatability test is based on the status of shutter opening
*4    Input the 550nm monochromatic light and measure the stray light ratio at 550nm ± 40nm
*5    Testing condition: Sync mode at 60Hz. Sample speed depends on the measured sample. If the sample uses PWM, it will take longer
