What is an AMOLED Display Screen?
AMOLED stands for Active Matrix Organic Light Emitting Diode. It¨s a type of display technology where each pixel is made up of organic compounds that emit light when an electric current passes through them. Unlike LCD screens, which require a backlight, AMOLED displays are self-illuminating, meaning each pixel generates its own light.
Key Components of an AMOLED Screen Module
OLED Layer: Composed of organic materials that produce light.
Thin Film Transistor (TFT) Layer: Controls the current flowing to each individual pixel, ensuring precision and high responsiveness.
Substrate Layer: Provides structural support for the display.
Touch Sensing Layer: Enables user interaction with the display via touch gestures.

How Does an AMOLED Display Work?
AMOLED technology relies on two primary mechanisms:
1. Light Emission by Organic Compounds
When an electric current flows through the organic compounds in the OLED layer, they emit light. Each pixel in an AMOLED display consists of red, green, and blue subpixels, which combine to produce a full spectrum of colors.
2. Active Matrix Control
The TFT layer uses an active matrix system to control each pixel individually. This system allows for faster refresh rates, higher responsiveness, and lower power consumption compared to passive matrix displays.
Touch Functionality Integration
The AMOLED screen module includes a touch sensing layer, which registers user inputs like taps, swipes, and multi-touch gestures. Capacitive touch technology is commonly integrated, ensuring seamless interaction.

AMOLED Display vs LCD: What¨s the Difference?
Comparing AMOLED displays vs LCD screens highlights the key advantages of AMOLED technology:
1. Brightness and Contrast
AMOLED: Offers true blacks since pixels can be turned off completely, creating an infinite contrast ratio.
LCD: Requires a backlight, resulting in less vibrant blacks and overall lower contrast.
2. Power Efficiency
AMOLED: More energy-efficient as only active pixels consume power. Displays with more black or darker content use significantly less energy.
LCD: Always consumes power to light the backlight, regardless of the image displayed.
3. Viewing Angles
AMOLED: Superior viewing angles with minimal color distortion.
LCD: Limited viewing angles and color shifts at extreme angles.
4. Thickness and Flexibility
AMOLED: Can be made thinner and flexible, enabling curved and foldable displays.
LCD: Bulkier and rigid, with limited flexibility.
