LCD is short for liquid crystal display, and although LCD technology has been around for some time, it has only been in the last decade that the technology has become suitable for high-quality flat-panel televisions and high-quality screens. computer we see today. The most notable feature of displays that use LCD technology, of course, is the thinness of the unit, but the power behind that slim design is quite ample.
The screen of an LCD panel is made up of image elements, or pixels, as computer experts around the world know. The resolution of the flat panel is partially determined by the number of pixels on the screen. A typical LCD panel display can range from hundreds of thousands of pixels to millions of pixels and the higher the number of pixels, the better the resolution. LCD TVs come in many different shapes and sizes, but are generally designed to accommodate an aspect ratio of 16 to 9. This ratio makes them perfect for viewing widescreen displays such as DVDs as well as traditional television programs.
What are the differences between LCD and traditional TVs?
LCD televisions, flat panel computer monitors, and other devices have a number of built-in benefits, and it is these benefits that have made them a hit with technology buyers around the world. Some of the many benefits of LCD technology include:
Brighter Screen: LCD TV screens are brighter than traditional CRT TV screens, due to the special way they work. While a traditional CRT television or monitor uses a tube to create the screen, the LCT television uses pixels, which provide a brighter screen.
Flicker-free performance: The LCD TV screen or computer monitor will also be flicker-free, as the LCD screen will have a constant light source all over the screen. Once the pixel is on, it stays on. Compare this to the design of the CRT TV or monitor, which should periodically refresh the screen with a beam of light moving across the monitor or TV.
Low Power Consumption – Another big advantage of the LCD TV is its superior energy efficiency. LCD TVs will be up to 65% more energy efficient than traditional TVs, helping to protect the environment and save money.
Ultra-Thin Design: Obviously it’s the slim and elegant design that catches the eye and catches the attention of buyers. LCD screens can be as thin as 49mm (just over 19 inches), which means these TVs can be placed just about anywhere.
Wall Mountable Designs – Many LCD TVs are so slim that they can hang on the wall like you would a painting. Obviously, it is important to purchase a wall mount bracket suitable for supporting the weight of the unit.
A guide to some LCD TV terms
If you are looking for an LCD TV, you will probably hear a number of new and sometimes confusing terms. It is important to understand what these words mean to you, the television tech buyer.
Aspect Ratio: The aspect ratio of your TV helps determine its suitability for watching movies and TV shows in true widescreen format. While traditional television has always used a 4: 3 aspect ratio, i.e. 4 “wide and 3” high, the typical LCD television uses a 16: 9 aspect ratio, which provides a truer, perfect Widescreen image. to watch DVD and VHS movies. as well as traditional television programming.
Candle – One of those words you may hear from time to time is candle. Simply put, the candle is a standard unit of brightness and is equal to the number of candles that would be needed to produce the same intensity of light. Therefore, a rating such as 450 cd / m2 means that a concentration of 450 candelas in a square meter area would be needed to produce the same amount of light.
Contrast Ratio: The contrast ratio is simply the difference in light intensity between the darkest black and the brightest white on the screen. The higher the contrast ratio, the sharper and cleaner the image will be.
