Abstract
A camera colorimeter system simultaneously lights up one or more pixel units on a display panel, each pixel unit including colored subpixels, for characterization of the display panel. The system includes optical elements that directs the light emitted by the simultaneously lit one or more pixel units to a filter and a corresponding imaging device. Each filter is configured to block wavelengths of light other than predetermined range of wavelengths, thereby ensuring that each imaging device captures a filtered spectrum of light that originates from subpixels of the same color. Using the filtered spectrum, the system reconstructs the full spectrum of light, which can subsequently be used to regenerate the display characteristics of each pixel unit (and corresponding colored subpixels). Thus, the camera colorimeter system can characterize a display panel in significantly less time as compared to conventional systems and methods.
