What Is Super-AMOLED (S-AMOLED)?


Overview of AMOLED Technology

AMOLED stands for Active Matrix Organic Light Emitting Diode, which is a display technology used in a wide range of electronic devices, including smartphones, tablets, and televisions. It is known for its vibrant colors, deep blacks, and excellent contrast ratio. Unlike traditional LCD displays, AMOLED does not require a backlight to illuminate the pixels. Instead, each pixel generates its own light, resulting in a more energy-efficient and thinner display.

AMOLED technology works by using an array of organic compounds that emit light when an electric current is passed through them. Each pixel in an AMOLED display is made up of these organic compounds sandwiched between two thin layers of electrodes. When a current is applied, electrons from the cathode layer flow through the organic compounds, creating light. The display can then control the brightness and color of each individual pixel by adjusting the amount of current passing through it.

One of the key advantages of AMOLED technology is its ability to display true blacks. Since each pixel can be turned off completely when displaying black, AMOLED panels can achieve an infinite contrast ratio, resulting in deeper blacks and more vibrant colors. This is in contrast to LCD displays, which require a backlight that can leak light through the pixels, making it challenging to achieve true blacks.

In addition to improved contrast ratio, AMOLED displays also offer faster response times and wider viewing angles compared to LCD panels. This is because the organic compounds used in AMOLED technology can switch on and off much faster than the liquid crystal molecules found in LCD displays. This fast response time makes AMOLED displays ideal for gaming and multimedia applications, where fast-moving images need to be displayed without blurring or ghosting.

Furthermore, AMOLED displays are flexible, allowing manufacturers to create curved and bendable screens. This flexibility opens up new possibilities for innovative design and form factors in devices such as smartphones and smartwatches. The lightweight and thin nature of AMOLED panels also contribute to the slim and sleek profiles of modern devices.
