“…color and intensity for each pixel, allowing the simulation of global as well as local backlight driving schemes. The temporal LC behavior is modeled as described in [6]: The output of the temporal LCD model is derived by concatenating the step response to the addressed gray level in each pixel, depending on the current state the pixel is in. The step response itself is oversampled, leading to a number of simulated frames per input frame.…”

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.

Abstract— In this paper, two models to evaluate the temporal behavior of liquid‐crystal displays are described: a model assuming a linear display behavior and a model that incorporates non‐linear effects. For the linear temporal model, it can be predicted that the response time starts to contribute to motion blur when it is longer than one‐sixth of the hold time and becomes dominant when it is longer than eight times the hold time. The non‐linear model can be used to visualize the appearance of effects that cannot be determined via linear system theory. Also, some means to reduce display artifacts are described and its impact is illustrated. Although the main focus in this article is on the temporal behavior of liquid‐crystal displays, the spatial properties defined by the pixel structure can be simulated as well. A formula for the spatio‐temporal display behavior is given, which can be evaluated numerically to simulate the perceived image for arbitrary image‐sequence input material.
