Abstract
Embodiments relate to determining characteristics of a display panel by using capturing images through multiple filters where the multiple filters include at least two filters that collectively enable replicating of a color matching function. At least two filters of the multiple filters have transmission profiles that correspond to the same color matching function (x color matching function) in different wavelength ranges. Image capturing devices capture the display panel through respective filters. The captured images are processed to the display characteristics of pixels or regions of the display panel.
