AMOLED vs TFT: Difference and Comparison

AMOLED (Active Matrix Organic Light Emitting Diode) offers vibrant colors, deep blacks, and high contrast ratios. TFT (Thin Film Transistor), on the other hand, is a type of LCD (Liquid Crystal Display) technology known for good image quality but lower contrast ratios compared to AMOLED displays.

Key Takeaways

  1. AMOLED displays have better color reproduction, deeper blacks, and higher contrast ratios than TFT displays.
  2. TFT displays are more power-efficient than AMOLED displays.
  3. AMOLED displays have more flexibility in terms of design due to their ability to bend and curve, while TFT displays are more rigid.


AMOLED displays use organic compounds that emit light when an electric current is passed through them, while TFT displays use thin-film transistors to control the flow of liquid crystals. AMOLED displays offer better contrast ratios and more vibrant colours than TFT displays.

What is AMOLED?

AMOLED, which stands for Active Matrix Organic Light-Emitting Diode, is a display technology used in various electronic devices, particularly in smartphones, tablets, and smartwatches. It is known for its vibrant colors, high contrast ratios, and flexibility, making it a popular choice in the consumer electronics industry.

How AMOLED Works (H3)

1. Active Matrix

In AMOLED displays, each pixel is controlled by its own thin-film transistor (TFT) within an active matrix. This allows for precise control over each individual pixel, contributing to better image quality and responsiveness.

2. Organic Light-Emitting Diode

The organic compounds used in AMOLED displays emit light when an electric current is applied. Unlike traditional LCD (Liquid Crystal Display) technology, AMOLED does not require a separate backlight, resulting in thinner and more flexible displays.

Advantages of AMOLED

1. Contrast Ratio

AMOLED displays offer an exceptional contrast ratio, providing deep blacks and vivid colors. Each pixel emits its own light, allowing for precise control over brightness levels.

2. Color Reproduction

The organic compounds used in AMOLED displays are capable of emitting light across a wide spectrum. This results in vibrant and accurate color reproduction, enhancing the visual experience for users.

3. Flexibility

AMOLED technology allows for flexibility in display design. Manufacturers can create curved or flexible screens, enabling innovative form factors in devices like foldable smartphones.

4. Faster Response Time

The individual pixel control in AMOLED displays leads to faster response times compared to traditional LCDs. This is particularly beneficial in applications where quick screen transitions and smooth animations are crucial.

Challenges and Considerations

1. Burn-In

One challenge associated with AMOLED displays is the potential for burn-in, where static images displayed for extended periods may cause permanent damage to certain pixels.

2. Cost

Manufacturing AMOLED displays can be more expensive than other technologies, impacting the overall cost of devices that incorporate this display type.


AMOLED technology is widely used in various electronic devices, including smartphones, smartwatches, televisions, and virtual reality headsets. Its ability to provide vibrant colors, high contrast, and flexibility has contributed to its popularity in the consumer electronics market.


What is TFT? 

TFT stands for Thin Film Transistor. It is a type of transistor commonly used in liquid crystal displays (LCDs) and organic light-emitting diode (OLED) displays.

Structure and Function

Thin Film

The “thin film” in TFT refers to a layer of semiconductor material that is deposited on a substrate, using techniques like physical vapor deposition (PVD) or chemical vapor deposition (CVD). This thin film serves as the active channel through which electrical current flows.


The transistor in TFT is a crucial component that regulates the flow of electrical current. In TFT technology, amorphous or polycrystalline silicon is commonly used as the semiconductor material for the transistor.

Application in Displays

TFT technology is widely used in flat-panel displays, such as LCDs and OLEDs. In an LCD, each pixel is associated with an individual TFT, which acts as a switch to control the passage of light through the pixel. This enables precise control over the color and intensity of each pixel, contributing to high-resolution and vibrant displays.

Advantages of TFT

  • High Resolution: TFT technology allows for the creation of high-resolution displays.
  • Fast Response Time: TFT-based displays have fast response times, reducing motion blur.
  • Improved Image Quality: The precise control over individual pixels enhances image quality and color accuracy.
  • Versatility: TFT technology can be applied to various display types, including LCDs and OLEDs.

Main Differences Between AMOLED and TFT

  • Display Technology:
    • AMOLED: Uses organic compounds that emit light individually when an electric current is passed through them.
    • TFT: Employs thin film transistors for pixel control in LCD displays.
  • Image Quality:
    • AMOLED: Offers vibrant colors, deep blacks, and high contrast ratios.
    • TFT: Provides good image quality but lower contrast ratios compared to AMOLED displays.
  • Power Consumption:
    • AMOLED: Generally more energy-efficient, as pixels emit light individually and can be turned off to display true black.
    • TFT: Consumes more power, as the backlight is always on, even when displaying darker images.
