Smartwatches are one of the most popular wearables on the market today. They come in a wide range of styles and sizes, and they offer an impressive array of features, from fitness tracking to mobile payments. One of the key components of any smartwatch is its display. The type of display technology used in a smartwatch can have a significant impact on its performance, battery life, and overall user experience. In this article, we will compare two popular display technologies used in smartwatches: AMOLED and TFT.

Amoled vs TFT Display

AMOLED vs TFT display has been a popular topic of debate when it comes to choosing a smartwatch. With the advancement of technology, the options for smartwatches have increased significantly, and one of the most crucial aspects of a smartwatch is its display. The display is responsible for the user's experience, from the quality of the image to the readability in bright sunlight. Therefore, choosing the right display technology is essential for a satisfying user experience.

AMOLED (Active-Matrix Organic Light-Emitting Diode) and TFT (Thin Film Transistor) are two popular display technologies used in smartwatches. Both technologies have their own set of advantages and disadvantages, and each is better suited for specific use cases. Understanding the differences between the two can help consumers make informed decisions and choose the right smartwatch for their needs.

AMOLED displays are known for their superior image quality, with deep blacks, high contrast ratios, and wider viewing angles. This is because AMOLED displays do not require a backlight, unlike TFT displays. Instead, each pixel in an AMOLED display emits light individually, resulting in brighter colours and deeper blacks. On the other hand, TFT displays are more affordable and offer better outdoor visibility in bright sunlight. This is because TFT displays use a backlight to illuminate the screen, making it easier to read in direct sunlight. However, TFT displays have lower contrast ratios and narrower viewing angles compared to AMOLED displays.

When it comes to choosing between AMOLED and TFT displays in smartwatches, it ultimately depends on the user's priorities and preferences. Some may prioritise image quality and battery life, while others may prioritise cost or outdoor visibility. Ultimately, the right choice will depend on your specific needs and use case.

Overview

Technology is evolving both on micro and macro levels. When it comes to smartwatches, the display is one of the most important factors to consider. Two of the most common types of displays you'll come across are AMOLED and TFT.

So, which one should you choose? It really depends on your priorities. If you want a smartwatch with a beautiful, vibrant display and good battery life, a smart watch with an AMOLED display is likely the way to go. However, if you prioritise visibility in bright sunlight and don't mind sacrificing a bit of colour saturation, a TFT display may be a better choice.

As per the current trends, AMOLED displays are becoming popular in high-end smartwatches. Many top-end brands, such as Noise, use AMOLED displays to provide superior image quality and longer battery life.

On the other hand TFT displays are generally cheaper and consume less power than AMOLED displays. They also offer better visibility in bright light and have a longer lifespan. Additionally, TFT displays are compatible with a wider range of devices and have a faster response time, making them ideal for gaming and high-speed applications.

Moreover, with the increased development of more high-quality screens, you can also have a wider variety of shapes and sizes of smartwatches. For instance, Noise brings you round-shaped smartwatches under both AMOLED and TFT displays with other exciting deals. 

Overall, both AMOLED and TFT displays have their pros and cons when it comes to smartwatches. It's up to you to decide which one best fits your needs and preferences.

What is an AMOLED display?

AMOLED stands for Active-Matrix Organic Light Emitting Diode. This is a type of display technology that uses organic compounds to emit light and create colours. Each pixel on an AMOLED display is made up of three subpixels: red, green, and blue. When an electric current is applied to these subpixels, they emit light of different colours, which combine to create the full spectrum of colours needed to display images and text.

One of the key advantages of AMOLED displays is their high contrast ratio. This means that the difference between the darkest and lightest parts of an image is more pronounced, resulting in a more vibrant and lifelike image. AMOLED displays also offer wider viewing angles which means that colours and brightness remain consistent even when viewed from off-centre angles.

AMOLED displays are also known for their power efficiency. Because each pixel on an AMOLED display emits its own light, there is no need for a separate backlight. This means that when a pixel is displaying black, it is actually turned off, which saves power. Additionally, AMOLED displays can be designed to use less power when displaying content that is primarily dark or black.

What is TFT display?

TFT stands for Thin Film Transistor. This is a type of LCD (Liquid Crystal Display) technology that uses thin film transistors to control the pixels. TFT displays work by using a backlight to shine light through a series of polarising filters and liquid crystals. The liquid crystals rotate to block or allow light through to create the desired image.

TFT displays are known for their high brightness and colour accuracy. They are also relatively inexpensive to manufacture, which makes them a popular choice for lower-priced smartwatches. However, compared to AMOLED displays, TFT displays have a lower contrast ratio and narrower viewing angles. This can result in images that appear less vibrant and may be more difficult to see when viewed from off-centre angles.

TFT displays also tend to consume more power than AMOLED displays. Because TFT displays require a separate backlight, they consume more power when displaying bright colours or white backgrounds. This can lead to shorter battery life on devices with TFT displays.
