Fourier optics viewing angle instruments are now widely used to check the viewing angle behaviors of displays in terms of luminance, contrast and color. In the present paper we introduce a new generation of EZContrast instruments that provides not only luminance and color at any incidence and azimuth angle but also the full spectral radiance in all the visible range. After a description of the new system we show that these new measurement capacities are useful in different situations: for the LCD emissions, each color behavior can be understood in all its details and color variations measured with an un‐precedent accuracy; for display components, their angular and spectral transmittance properties are useful for best understanding and more precise optical simulations.
