Display Screens With 4 Colours

     I've been wanting to mention this for awhile now.

It seems that there is going to be some changes taking place in
our displays, whether computer monitors or TV's. Currently, all
displays are 3 colors, red, blue, green. In the very near future,
they will be red, blue, green and black/white (same pixel).

When you turn down (all the way) red, blue and green, you get
dark red, dark blue and dark green, not black. If the colors are
turned up all the way, you get bright colors, but not white.
Introducing a 4th pixel that can be true black when turned all
the way on or, white (transparent- no color) when turned off, adds
additional contrast while reducing power requirements for brightness.
This new technology does not require different recording formats
or broadcasting, it's strictly internal to the display. How the
signal is used for 4 colors instead of 3.

The new displays will start out as computer monitors (predominately
LCD based), but eventually will be manufactured for entertainment
(TV's- CRT and Plasma). If I recall properly, Samsung is going to
be the first to produce these devices.

This technological change over isn't decades away, it's going to
start in less than a year. I predict, we'll be seeing the new TV's
for entertainment in 3 years or less

Certainly would help with gaming and action videos, to be able to control
the contrast pretty much per pixel.
Much more depth of colour.

** An equal mix of R,G and B pixels always produces white  -  you fool.

**  CRTs cannot produce black  -  the three colour dots ( or rectangles )
are surrounded by black already.

RGB (red, green, blue) displays I mean have been, and will
continue to be the preferred display option for many, many
years to come.....

Actually Phil I'm having second thoughts now after posting
the article I copied.... I will have to wander back to where
I found it and ask if the original poster is playing a prank...

I remember reading about this in some engineering rag recently. I
beleive that TI(iirc) is already using this technology in their DLP's
for projectors. Samsung also use this technology from memory in LCD's.

In saying this, i also remember that the RGBW technology is mainly
reserved for things like hi res PDA's screens etc, where the pixel
density is high and the light output is low due the small size of the
pixels. I cant see this having any real use in larger screens such as
tv's.
