![]() This technology display light using a process called electrophosphorescence. The substrate is either plastic or glass that supports the display panel. An OLED display is comprised of a substrate, an anode, a conductive layer, an emissive layer, a cathode, and the cover. So all LEDs switched on the same time gives you white color and similarly switching off all the LEDs together gives black color. When you light them up together in different intensities, you will get more colors in the spectrum. OLED is a type of display in which each LED lights up one at a time. The Organic Light Emitting Diode commonly referred to as OLED. The LEDs used are in the primary shades namely Red, Blue, and Green and are grouped in triangle-shaped pixelated forms. These same LED lights are used in AMOLEDs, but of course in the smallest size possible. You might be familiar with the giant LED bulbs used in parties or even as indicators on televisions showing the on/off state. Thus a display monitor using the active matrix technology has a clearer output for fast-moving images compared to one using the old passive matrix technology. ![]() The improvement in response time is the major advantage of switching to this new technology. The major difference between the two technologies apart from the components used is the fact that in a passive matrix, the entire row of wires needed to be charged to modify each pixel whereas now the pixels can be altered directly. ![]()
