What is the difference between TFT and OLED displays?
Have you ever wondered why some computer monitors look more vibrant and beautiful than others? That’s because of different display technologies! Today, let’s take a look at the differences between TFT and OLED monitors and which one is best for us.

In the world of display technology, the competition between TFT and OLED is getting more and more intense. Each finland mobile database has its own advantages. OLED stands out with deep blacks and high contrast, while TFT still reigns supreme in brightness and longevity. Whether you are a professional or a casual user, understanding the differences between these two technologies will help you choose the right monitor for you. Let's see what the pros and cons of both technologies are!

Summary of key points
OLED displays offer superior picture quality with higher contrast and deeper blacks, while TFT displays offer better brightness and longer life.
TFT displays are 30-50% cheaper and more durable, with a lifespan of over 50,000 hours compared to OLED displays’ 30,000-40,000 hours.
OLED displays offer a wide viewing angle of up to 178 degrees without color distortion, while TFT displays start to distort beyond 160 degrees.
OLED displays consume less power when displaying dark images, while TFT displays consume constant power regardless of whether the image is bright or dark.
OLED displays are prone to burn-in and image retention, while TFT displays are more resistant to these issues.
Understanding display technology
TFT and OLED screens

TFT and OLED display work on completely different principles. TFT uses liquid crystal molecules controlled by transistors to modulate the light from the backlight, while OLED uses organic materials that glow when an electric current is passed through them .

The main difference is in how the light is illuminated: TFT displays require a backlight that passes through multiple layers, including a polarizing filter and a color filter, while OLED displays generate their own light at the pixel level via electroluminescence .

This technological difference has a direct impact on performance, with TFT displays offering superior brightness and longer lifespan at a lower cost, while OLED displays excel in contrast ratio and color accuracy through their self-illuminating pixel structure.

The main differences between TFT and OLED displays
The display technology between TFT (Thin-Film Transistor) and OLED (Organic Light-Emitting Diode) is very different in terms of the main working mechanism.

The key differences are as follows:

Light generation: TFT relies on a backlight shining through a liquid crystal, while each OLED pixel can generate its own light.
Power efficiency: OLED consumes less power when displaying dark images, while TFT consumes constant power.
Contrast ratio: OLED offers very high contrast and deeper blacks, while TFT has more limited contrast.
Color display: OLEDs deliver more vibrant colors with pixel-level control , while TFTs rely on color filters.
How does each technology work?
Display technologies work by completely different mechanisms, which affects their capabilities and limitations. TFT displays use liquid crystals that twist and untwist to control the passage of light from a backlight, while OLED displays use organic materials that glow when an electric current is passed through them.
