What is TFT vs LED panel?

TFT (Thin Film Transistor) and LED (Light Emitting Diode) refer to different aspects of display technology, and they are not mutually exclusive. In fact, they are often used together in modern display devices. Let's break down what each term means:

TFT (Thin Film Transistor):

TFT is a type of technology used in the construction of liquid crystal displays (LCDs).
In a TFT-LCD, each pixel is controlled by its own thin film transistor, allowing for more precise control over individual pixels.

TFT technology is commonly used in various types of displays, including computer monitors, televisions, and smartphone screens.

LED (Light Emitting Diode):

LED refers to the backlighting technology used in LCD displays.
In traditional LCD displays, a backlight is required to illuminate the pixels and make the image visible. LEDs have largely replaced older backlighting technologies like CCFL (Cold Cathode Fluorescent Lamp) due to their energy efficiency, longer lifespan, and better color reproduction.
LED backlighting can be implemented in different ways, such as edge-lit (lighting from the sides) or direct-lit (array of LEDs directly behind the display).

In summary, when people refer to a "TFT vs LED" panel, they might be comparing different types of display technologies, but it's important to note that TFT and LED are not mutually exclusive. TFT is a technology used in the construction of the display, while LED refers to the type of backlighting used to illuminate the display. In modern displays, TFT-LCD with LED backlighting is a common combination.
