I'm not necessarily talking about the ones that go into computer displays and cellphones, I'm talking about the older ones that have the larger pixels and the smaller resolutions.
There's this one thing I've been very curious about, but I can't seem to find any appreciable information on how it was done:
I had this toy computer thing that had what looked like a Passive Matrix LCD, but it was in color, instead of black and white. I read about color lcds having their pixels subdivided into red green and blue, but I could *swear* that it used a different method to make color on the screen, especially since the pixels were quite big, and the subdivided pixels would be quite obvious.
There was this one time where I left it in sunlight for a few hours, and when I came back, the display was completely black/navy blue. If I recall correctly, as the display faded back to normal, the color shifted from navy blue to red, and then back to normal.
Would anyone know what I'm talking about? I even remember my ti-83 being able to display blue pixels when the contrast was high enough, even though pixels were normally black on it.
