So what's the big deal with AMOLED and why is it better than the traditional screens we have today? As a basic, AMOLED technology can be used with capacitive or resistive touchscreens, a comparison we've previously explored, and even non-touchscreen devices. AMOLED, short for active matrix organic light-emitting diode, is a thin, bright display technology that doesn't require backlighting.

No Backlight = Richer Colors
Since there is no backlight, colors are brighter and blacks are truer because there is no light from the backlight to wash out the colors. This phenomenon is similar to the dark and bright rooms and how vivid the display is on the Microvision pico projector.

Technical
AMOLED works by having a thin film transistor (TFT) layer consisting of an array of OLED pixels that form a matrix. Upon activation with electrical energy, the OLED pixels will illuminate light to render whites and colors; blacks will be shown to the eye due to unactivated OLED pixels. According to Wikipedia, "The TFT array continuously controls the current that flows to the pixels, signaling to each pixel how brightly to shine."
