TFT vs AMOLED: Which is Better for Displays?


tft display vs amoled display







In today's tech-savvy world, we're surrounded by a vast array of electronic devices, each with its unique display technology. Two commonly used types are TFT (Thin-Film Transistor) and AMOLED (Active Matrix Organic Light Emitting Diode) displays. In this blog, we'll delve into what these displays are, explore their differences, consider their applications, and even guide you on where to find high-quality displays for wholesale purposes.


What is TFT Display and AMOLED Display?


TFT Display - The Basics

TFT, or Thin-Film Transistor, is a type of LCD (Liquid Crystal Display) technology. It consists of a matrix of thin-film transistors that control the individual pixels on the screen. TFT displays are known for their excellent color reproduction, sharpness, and reliability. They have been the go-to choice for various applications, from smartphones to computer monitors.


Is TFT Display Good for Eyes?

TFT displays are commonly used in many devices, including computers, televisions, and smartphones. However, like any digital screen, prolonged use can potentially cause eye strain or discomfort. This is not unique to TFT displays, but applies to all types of digital screens, including AMOLED and LCD.


The main factors that can affect eye comfort when using a TFT display (or any digital screen) include:

  1. Brightness and Contrast: Screens that are too bright or have high contrast can cause eye strain. It’s important to adjust the brightness and contrast to a comfortable level.

  2. Blue Light: All digital screens emit blue light, which can cause eye strain and disrupt sleep patterns if you’re exposed to it for too long, especially at night. Many devices now have a “blue light filter” or “night mode” option to reduce blue light emission.

  3. Screen Quality: Higher resolution screens with better color accuracy can be easier on the eyes. TFT screens can vary in quality, so a higher-quality TFT screen will generally be better for your eyes than a lower-quality one.

  4. Breaks: Regardless of the type of screen, it’s important to take regular breaks to rest your eyes. The 20-20-20 rule is often recommended: every 20 minutes, look at something 20 feet away for 20 seconds.


AMOLED Display - An Introduction

On the other hand, we have AMOLED, or Active Matrix Organic Light Emitting Diode, displays. These displays employ an organic compound layer that emits light when an electric current is applied. AMOLED screens are praised for their vivid colors, high contrast ratios, and energy efficiency. They have gained prominence in premium smartphones and high-end TVs.


Is AMOLED Display Good for Eyes?

AMOLED (Active Matrix Organic Light Emitting Diodes) displays are often considered better for the eyes compared to other types of displays like TFT or LCD. Here are a few reasons why:


  1. Better Contrast Ratio: AMOLED displays have a higher contrast ratio compared to other displays. This means they can display deeper blacks because each pixel is independently lit and can be turned off completely for black. This can reduce eye strain, especially in low light or dark conditions.

  2. Vibrant Colors: AMOLED displays are known for their wide color gamut, which can display more vibrant and accurate colors. This can make the viewing experience more pleasant and less straining on the eyes.

  3. Adjustable Brightness: AMOLED screens can adjust the brightness of each individual pixel, which can make the screen easier on the eyes in different lighting conditions.

  4. Less Blue Light: Some studies suggest that AMOLED displays emit less harmful blue light compared to LCD displays. Blue light can cause eye strain and disrupt sleep patterns.


Differences Between TFT and AMOLED Displays


  1. Contrast Ratio: AMOLED displays offer superior contrast ratios compared to TFT screens. This means deeper blacks and more vibrant colors, resulting in a visually stunning experience.

  2. Power Efficiency: AMOLED screens are more power-efficient because they only light up individual pixels when necessary. In contrast, TFT displays use a backlight, consuming energy even when displaying dark colors.

  3. Viewing Angles: AMOLED displays provide consistent image quality at various viewing angles, while TFT displays may experience color shifting and reduced visibility.

  4. Response Time: TFT displays typically have faster response times, which can be crucial for fast-paced applications like gaming.

  5. Durability: TFT displays are generally more durable and less susceptible to burn-in issues. AMOLED displays are known to be more vulnerable to permanent image retention.

TFT VS AMOLED Durability



AMOLED (Active Matrix Organic Light Emitting Diodes) displays are made from organic materials that emit light when electricity is applied. They are thinner, lighter, and more flexible than TFT (Thin Film Transistor) displays. This flexibility can make them more resistant to damage from drops or impacts.


AMOLED screens also have individual pixels that can be turned off, which not only saves battery life but also prevents issues like burn-in or image retention that can degrade the display over time. However, AMOLED screens can suffer from degradation of their organic materials over time, which can result in a loss of brightness and color accuracy. This is often referred to as "burn-in".


TFT displays, on the other hand, use a matrix of thin-film transistors to control the illumination of the display. They are generally less expensive to produce than AMOLED displays, but they are also heavier, thicker, and less flexible. This can make them more susceptible to damage from drops or impacts.


TFT screens can also suffer from issues like dead pixels, where individual pixels fail and become permanently stuck on a single color. This can result in noticeable spots on the display that can’t be repaired.


In terms of overall durability, both types of displays have their pros and cons. AMOLED displays are generally considered more durable due to their flexibility and the ability to turn off individual pixels, but they can suffer from burn-in over time. TFT displays are less flexible and more prone to damage, but they are also less expensive to replace if damaged.


Applications of TFT and AMOLED Displays


  • TFT Display Applications: TFT displays are commonly found in computer monitors, laptops, digital cameras, industrial control panels, and a wide range of consumer electronics. Their reliability and cost-effectiveness make them suitable for diverse applications.

  • AMOLED Display Applications: AMOLED displays are favored for premium smartphones, high-end televisions, and virtual reality headsets. Their superior visual quality and energy efficiency make them ideal for immersive and high-resolution applications.
