Physical pixel counts are not as effective as modulation transfer functions (MTFs) for characterizing the spatial imaging performance of displays. This study introduces a new method for measuring the MTF of a display by analyzing an image of a line reproduced on the display screen. The accuracy and consistency of this method is high for a wide range of pixel ratios, i.e., number of pixels of the measurement device per display pixel. The method is validated by using computer‐generated screen images of a model display with an RGB stripe subpixel arrangement.
