What’s the Difference Between LED and LCD Displays?
Before we dive into the identification process, it’s essential to understand the fundamental differences between LED and LCD displays. Both technologies use liquid crystals to block or allow light to pass through, creating images on the screen. However, they differ significantly in terms of their backlighting mechanisms.
LCD (Liquid Crystal Display) technology uses a CCFL (Cold Cathode Fluorescent Lamp) or EL (Electroluminescent) backlight to illuminate the liquid crystals. This backlight is usually located at the bottom or sides of the screen, and the liquid crystals control the amount of light that passes through, creating images.
LED (Light Emitting Diode) displays, on the other hand, use an array of LEDs as the backlight source. These LEDs are typically located along the edges or behind the screen, providing more precise control over the lighting. This results in better contrast, color accuracy, and energy efficiency.
Advantages of LED Displays
LED displays have several advantages over LCD screens, including:
- Better contrast ratio: LEDs can produce true blacks, resulting in an almost infinite contrast ratio.
