###Liquid Crystal Display TVs: What Types Are Available?
####What is a Liquid Crystal Display TV?
Liquid crystal display (LCD) TVs are one of the most popular types of televisions available in the market today. They use liquid crystals to block or allow light to pass through a matrix of pixels, creating images on the screen. LCD TVs have been around for several decades and have evolved significantly over time, with improvements in technology leading to better picture quality and more features.
####How Do LCD TVs Work?
The basic principle behind an LCD TV is that it uses a layer of liquid crystals to control the amount of light that passes through each pixel. The liquid crystals are aligned between two polarized filters, which allows them to be switched on and off by an electric current. When an electric current is applied, the liquid crystals align themselves so that they either block or allow light to pass through the pixel.
####What Are Some Common Features Of LCD TVs?
There are many different features that can be found on modern LCD TVs. Some common features include high definition (HD) resolution, wide color gamut (WCG), 3D capability, smart TV functionality, and voice control. HD resolution means that the TV can display more detailed images than older standard definition (SD) resolutions could.
In addition to these basic features, some higher-end models may also come equipped with advanced technologies such as OLED panels or quantum dot LEDs for improved color accuracy and brightness levels.
####What Are The Different Types Of LCD Panels Used In These Devices?
LCD panels are used in all modern televisions but there are several different types available depending on their characteristics like response time speed etc., including TN panels known for low cost but slower response times; IPS panels offering good viewing angles but less bright displays; VA panel which has deep blacks due its ability to completely switch off individual pixels when black colors need displaying; PLS panel which offers excellent viewing angles combined with good contrast ratio while maintaining affordability
