Generating Grayscales
The AG1 has a maximum frame rate frequency of 120 Hz. Using the higher frame
rate, combined with flat panel controllers designed for this faster display, it is
possible to generate usable grays through frame rate control and dithering. Many
video controllers use these methods with proprietary algorithms to generate
grayscales.
The response time of ICEBrite displays is much faster than LCDs, therefore not all
possible grayscales generated by the video controller are actually usable. Many of
the grayscales may flicker or swim. Careful testing is necessary to select
appropriate grayscales for an application, especially when the ICEBrite displays
are driven at less than their maximum frame rate.
