Have you heard of Active Matrix Organic Light-Emitting Diode (AMOLED)? It’s become one of the world’s leading display technologies. Most smartphones, in fact, now feature an AMOLED display. AMOLED displays are bright, energy efficient and support low-profile displays. What are AMOLED displays exactly?
AMOLED is a variant of organic light-emitting diode (OLED). OLED, of course, is a display technology that involves the use of organic self-illuminating pixels. OLED displays don’t require backlighting. The organic pixels used in OLED displays will illuminate themselves in response to an electrical current. As electricity flows through the organic pixels, they’ll produce light. AMOLED follows this same basic principle, but it uses an active matrix configuration.
An activate matrix configuration means the pixels are formatted as a grid. AMOLED displays still feature organic self-illuminating pixels — just like all OLEDs. The difference is that AMOLED displays feature these pixels printed in a grid-like pattern. There are rows and columns of pixels. Together, they form a grid. AMOLED displays have a grid or “active matrix” of pixels, which distinguishes them from traditional OLEDs.
Support for Thin Designs
One of the reasons AMOLED displays have become so popular is their support for thin designs. As previously mentioned, most smartphones feature an AMOLED display. Smartphones, of course, require the use of a thin display. They can’t feature large or thick displays. Otherwise, they would be bulky. This has prompted many manufacturers to use AMOLED displays in their smartphones.
No Backlighting Required
AMOLED displays don’t require backlighting. Backlighting is a lighting system that’s used in conjunction with a display. Liquid-crystal displays (LCDs) require backlighting, and there are many other display technologies that require backlighting. But AMOLED doesn’t require backlighting. AMOLED displays feature self-illuminating pixels. Their pixels will produce their own light when exposed to an electrical current, thereby eliminating the need for backlighting.
Another reason AMOLED displays are on the rise is their contrast. They offer a better contrast ratio than other displays. This is because each pixel in an OLED produces its own light. Therefore, some of the pixels can produce bright colors, whereas others can produce dark colors.
Low Energy Consumption
AMOLED displays consume less energy than many other types of displays. With their low energy consumption, AMOLED displays are commonly used in smartphones and other portable or mobile electronics that run on batteries. They still consume energy, but AMOLED displays are one of the most energy-efficient types of displays on the market.
