What is the difference between hdtv and lcd tv




















The shade of color is controlled by changing the relative intensity of the light passing through each shutter. Additionally, LED TVs generally have better black levels and contrasts, as well as slightly better color accuracy. Image Courtesy: maxgadgets. Add new comment Your name. Plain text.

Electric current is passed through the individual crystals, which allows the crystals to pass or block light to create images. LCD crystals do not produce light. An external light source, such as fluorescent or LED light bulbs, is needed for the image created by the LCD to become visible to the viewer. LCD TVs can be made very thin, allowing them to be hung on a wall or placed on a small stand on top of a table, desk, dresser, or cabinet.

With some modifications, LCD technology is also used in video projectors. LCD TV technology is resolution agnostic. In other words, LCD TVs can display a variety of resolutions, from p up to 8K, and, in the future, even higher depending on how TV makers want to provide consumers. Vizio, on the other hand, uses the term Quantum. These labels refer to TVs that use quantum dot technology to improve color performance.

The dots are clustered in different sizes, with each size producing a specific color range when hit by the light from LEDs. The result is richer colors that can be displayed on an LCD TV screen, especially images at higher brightness levels.

It uses less energy and can be made almost paper-thin. However, the main drawback is an overall lack of brightness. LCD TVs can produce higher brightness levels. LCD and plasma TVs share one thing in common. Both are flat and thin and can be wall-mounted. However, inside those thin cabinets, these TVs employ different technologies to display images for TV viewing.

Plasma TVs use pixels made of self-emitting phosphors a backlight isn't required to produce images. The advantage over LCD TVs is that each phosphor can be turned on and off individually, producing deeper blacks.

In addition, plasma TVs are subject to burn-in if a static image is displayed on the screen for too long a time period. Although LCD TVs can produce bright, colorful images, one problem these TVs had from the outset is that the motion response isn't that natural.

Over the years, several technologies have been employed that have improved things to varying degrees. One option is to increase how often the screen refreshes the image on the screen. For example, 60 Hz means that the screen refreshes 60 times a second, Hz refreshes at times a second.
