Which technology is primarily used in modern flat-screen televisions?

Modern flat-screen televisions primarily utilize LCD (Liquid Crystal Display) technology for their screens. LCD technology works by using liquid crystals that modulate light to produce images. In conjunction with an LED (Light Emitting Diode) backlight, which provides the necessary illumination, LCD screens can achieve high levels of brightness and vibrant colors.

While LED technology is often mentioned, it is essential to clarify that it refers to the backlighting method for LCD screens, not the screen technology itself. Therefore, when discussing modern televisions, referring to LCD is more accurate since it encompasses a broader range of applications, including various types of backlighting, such as edge-lit and full-array.

Plasma technology, although once popular for large-screen televisions due to its excellent color accuracy and wide viewing angles, has become less common due to its limitations in energy efficiency and heavier weight compared to LCD and LED technologies. CRT (Cathode Ray Tube) is an outdated technology that has largely been phased out in favor of flat-screen options, as it is bulkier and less energy-efficient.

Thus, LCD stands as the core technology that characterizes modern flat-screen televisions, with LED acting as a supporting enhancement for brightness and image quality.
