With the development of fast liquid crystal cells and with advent of backlight units with separate red, green and blue
light emitting diodes also first commercial color sequential display emerge. Another technique in commercial application
proposes implementing more than three subpixels and thus enhanced color gamut by using multiple color primaries. Also
the combination of both color mixture techniques is possible. It is thus desirable to have a simulation workbench at hand
that is flexible enough to adapt to the various possibilities of subpixel design and color sequences in display design to
evaluate the displayed image in advance. The combination of a multiprimary display model, which can emulate a
multiprimary display on a standard RGB LC display, and a spatio-temporal model, that describes LC pixel behavior to
arbitrary input signals over time, provides means for simulating the perceived image of a color-sequential display
behavior. This article describes the combined model and gives also simulation results that compare advanced displays to
conventional vertical stripe RGB LC display.
In this paper a model for the LCD moving image representation is presented. It is combined with a human visual system
perception model to analyze the influence a display has on the perceived image quality. Two main fields of moving
image representation are discussed: The spatial properties of a display, namely the pixel shape or spatial aperture, and the
temporal properties of a display given by the display response or temporal aperture. Both properties affect the image
quality: The LCD pixel shape leads to a higher sharpness impression but also to an enhancement of errors such as block
noise. The temporal LCD hold-type behavior combined with the slow response of the liquid crystal lead to a motion blur
in moving objects. Both effects are explained numerically and analytically and demonstrated with simulation results.
