Colour LCD

Hi Rune, You could try modulating it to get shades of RGB. Just out of curiosity, whats the pixel size?

Hello

I have bought a LM64C152 colour LCD screen. Is it possible to create more than 8 different colours on the screen?

There is three different pixel colours Red, Green and Blue but each colour is on or off because there is only one bit per pixel.

Thanks Rune Christensen M.Sc.E.E

Hello

Thanks for the idea.

You can find the datasheet at

PC displays dither the pixels. Consider your triads in groups of four, which you could call a "super-pixel". Then you could haven in effect 15 levels of each color (plus off, of course). (you could do it with 2x, 3x, or whatever).

They've been doing that on PCs for years. :-)

Good Luck! Rich

Just remember to keep the refresh rate above 25Hz or so. Otherwise the flicker will be annoying.

While this is all true, it is perhaps worth pointing out that it *is* common for LCD controllers to implement multiple colour "shades" by modulation of the pixels.

Hi Rune,

Since this is a _passive_ matrix color LCD, using shades does not make much sense. The colors are not that clear and stable as on a TFT. ALso, colors heavily depend on the ambient temperature and on the viewing angle.

Does this stmt have something to do with the fact that most people who are colorblind are males???
