“Thin film transistor” and “light emitting diode” are two terms used to describe different parts of a liquid crystal display screen. It is possible for a LCD to use both TFT and LED technology at the same time. TFT technology handles how the pixels are displayed on the screen whereas LED refers to how the screen lights up. Most consumer LCD displays use TFT technology; however, some higher-end screens use Organic Light-Emitting Diode technology instead. LED are an improvement over fluorescent back-lighting technology.


This is a type of LCD with a thin film transistor attached to each pixel. All computer LCD screens are TFT since the early 2000s; older ones had slower response times and poorer color. Cost is now very good; power consumption is fairly good but dominated by the backlight. Has to be manufactured out of glass. The TFT layer is embedded in the screen itself, it reduces crosstalk between pixels. Crosstalk happens when a signal sends to a pixel also affects the pixel next to it. This makes the TFT technology the technology offering the best resolution and image quality. It also makes it a bit more expensive. Today TFTs have become the standard when producing LCD screens.


LED stands for a light emitting diode. As the name suggests, emits light rather than blocking it like LCD. Used for red/green/blue/white indicator lights everywhere. Some manufacturers advertise “LED” displays that are TFT screens with a white LED backlight, which is just confusing. Ones that are real LED screens are usually OLED.

What is the difference between TFT and LED?

TFT and LED screens both use LCD technology; the only distinction is in the backlighting. CCFL (cool compound fluorescent lamp) is used by TFT LCD Displays whereas LED is used for the other’s backlight.

When compared to TFT, LED uses less power since, as you are probably aware, it uses significantly less power than a CFL. Additionally, the CCFL configuration would be in an array behind the screen to provide uniform illumination. As a result, it uses more energy.

In the case of LED monitors, LEDs are positioned next to the screen’s edges.

The only negative effect of this would be that occasionally the corners would be brighter than the center. You might also believe that they use white LEDs, but in reality, they actually use blue LEDs that have been coated in phosphorous to appear white. The composition of this coating might fluctuate, which affects the color tone that different firms display.

TFT technology will eventually be implemented on more expensive gadgets as it advances. TFT displays were utilized by Samsung in the midrange Galaxy A13 and Galaxy A23 models in 2022. Those improvements may already be taking place. The most common display type currently found in contemporary cell phones is LCD.
