What Is OLED?
OLED, or Organic Light-Emitting Diode, is a display technology where each pixel emits light independently. It’s used in devices like smartphones, TVs, and smartwatches for its ability to produce vibrant colors and deep blacks.
How OLED Works
OLED uses organic compounds that emit light when electric current passes through them. Each pixel contains multiple sub-pixels — red, green, blue, and often yellow — which combine to create a wide range of colors. Since pixels illuminate individually, OLED screens don’t require a backlight, making them thinner and more energy-efficient than traditional LCDs. But, their performance may degrade over time because organic materials are prone to wear.
Key Features Of OLED
Self-Emissive Pixels
OLED’s self-emissive nature allows for perfect black levels. Pixels can turn off completely when displaying black, achieving an infinite contrast ratio. For example, when watching space scenes in movies, you notice true black areas without any light bleed.
Wide Viewing Angles
Colors and brightness remain consistent even at extreme angles, unlike LCDs where the picture quality diminishes. This feature benefits group viewing experiences, such as family movie nights or presentations.
Thin and Flexible Displays
OLED panels are thinner and lighter due to the absence of a backlight. Some displays are even bendable, enabling innovations like foldable smartphones and curved monitors. Products like the Samsung Galaxy Z Fold showcase this versatility.
Vivid Colors and High Brightness
OLED delivers a broader color gamut and brighter visuals. It’s ideal for applications requiring striking visuals, such as photo editing or gaming. Yet, prolonged exposure to static images may lead to “burn-in”, causing permanent image retention.
What Is AMOLED?
AMOLED (Active Matrix Organic Light-Emitting Diode) is an advanced display technology combining OLED’s self-emissive properties with an active matrix backplane. This integration enables faster pixel response times and enhanced power efficiency, making it ideal for modern devices.
How AMOLED Works
AMOLED employs an active matrix to control individual pixels on the display. Each pixel emits light through organic compounds like in OLED, while thin-film transistors (TFTs) and capacitors drive and regulate the pixel’s illumination. The active matrix ensures precise control of each pixel’s brightness, resulting in smoother performance during high-speed animations and videos.
Unlike passive-matrix OLEDs, AMOLED excels in energy conservation. Only active pixels consume power, which is especially advantageous during dark-mode usage. If you’re watching a movie with dark scenes, the display reduces energy consumption significantly by lighting fewer pixels.
