By Jeffrey R. Harrow, TechWeb News LCD screens have come a long way from the days when they were hard to look at for any length of time.
New screens are incredibly bright and detailed and infinitely easier on the eyes.
And with prices dropping, LCDs are increasingly appearing on desktops. But even as good as today's LCDs are, flat-panel displays are about to get better. One of the problems with LCDs is that pixels do not produce any light. In fact, each pixel selectively blocks light, which typically comes from behind the screen. The backlight is white, and the various red, green, and blue pixels are turned on and off to filter out the colors that don't belong at that spot on the screen.
