Good luck in your endeavor, though.
Actually your info is a bit old. Wikipedia also talks about FRC (Frame Rate Control / Temporal Dithering) which is used by many LCD panels (especially the larger ones) to achieve more colors. This switches the pixels between two brightness levels at high speed (which can be seen as flicker in some cases), to appear as an intermediate brightness pixel.

Supporting evidence:

Here is one of many (newer) wikipedia pages that talk about this:

While typically thought of as a mark of older systems like 16-bit game consoles, the flicker technique continues to be used on new systems, such as the temporal dithering used to fake true color on most new LCD monitors.
Flicker is also common on small LCD panels, such as those used in cheap cellphones.
