Television is an electronic device that displays audio and visual content. It is a medium for transmitting and receiving signals for entertainment, information, and education.
A television receiving set is an electronic system that transmits pictures and sound over a wire or space.
Television is a medium for the transmission of audio and video signals for their reproduction on screens. Its primary function is the broadcasting of shows that serve as sources of entertainment, information, and education.
A standard TV turns the video signal into beams of tiny particles called electrons. Through a picture tube, it sends these beams to the back of the screen. In a series of rows, the beams "paint" the pixels on the screen to make the picture.
A video camera takes pictures and sounds for a TV show and saves them. It turns the sounds and pictures into electrical signals. A TV set gets the signals and turns them back into pictures and sounds. The microphone in the camera changes the sound into what is called an "audio signal," which is an electric signal. The TV signal is made up of the video signal and the audio signal.
Like a computer, a digital TV signal sends pictures and sounds as a series of numbers. A digital signal can carry more information than a standard signal, so it can make better pictures and sounds.
A TV set can get a TV signal in more than one way. Local TV stations send signals through the air as radio waves using antennas. Cable TV stations send their signals through cables that run under the ground. Satellites, which are spacecraft that travel high above Earth, can send signals to special antennas called satellite dishes.
The picture on a CD and a plasma TV is different. They don't use an electron beam and a picture tube. LCD and plasma TVs are much thinner and lighter than regular TVs because they don't have a picture tube.
Television technology has evolved, but the basic process involves turning video and audio signals into electrical signals, transmitting them to the TV set, and displaying them on the screen.
There are several types of televisions on the market today. LCD TVs, which use liquid crystals and polarizers to create images, are among the most popular. OLED TVs, which use organic light-emitting diodes, offer even better picture quality. QLED TVs use quantum dots to improve colour and brightness. Plasma Display Panels use ionized gas to light up pixels, while DLP TVs use millions of tiny mirrors to display images. Full HD and Ultra-HD TVs offer high-resolution pictures, and flat and curved screens are available.
Let’s look into the differences between the various types of televisions:
A liquid crystal display (LCD) TV is one of the most popular types of TV. They use a technology called "liquid crystal", which uses liquid crystals and polarizers to make pictures on the screen. LCD TVs have three polarised glass panels called substrates. In between the substrates are liquid crystals. Red, blue, and green are the colours of the panels. When an electric current goes through them, the crystals rotate and line up so that light can pass through the other substrate.
OLED TV - Organic Light Emitting Diode, or OLED, TVs are similar to LCD TVs and came on the market in 2012. The main difference between an OLED and an LCD is that OLEDs use organic light-emitting diodes instead of LEDs. When an electric current goes through these compounds, they light up. This makes for great picture quality and colour display.
Quantum Light Emitting Diode (QLED) TVs - are one of the most popular types of TVs on the market right now. Instead of LED lights, QLED TVs use quantum dots, which are tiny nanoparticles. When an electric field goes through them, the dots get charged, which makes the colours and brightness better.
Plasma Display Panels: In the early 2000s, when many people switched from regular cathode ray TVs to plasma TVs, plasma TVs became very popular. Plasma is an ionised gas that can respond to electricity. The grid-like shape of the TV screen is filled with Plasma, which lights up the pixels.
Digital Light Processing TVs, also called DLP TVs, came out in the 1980s. DLP TVs use a chip called the Digital Micromirror device (DMD), which is made up of millions of tiny mirrors called Pixels. When an electric field is put on these mirrors, they tilt either toward or away from the screen, which shows the images.
Full-High Definition, or Full HD, TVs have 1920 pixels across the width of the screen and 1080 pixels across the height. They are cheaper than TVs from the last generation, and they can take Full HD signals from broadcasters without having to change them to a lower resolution.
Ultra-HD or UHD TVs - Compared to a normal HD or TV, an Ultra-HD or UHD TV has a higher resolution and better picture quality. A picture with a higher number of pixels has a higher resolution and is sharper.
Flat TVs have a thin, flat screen that can run on any technology, such as Plasma, LED, 4K, 8K, etc. Most TVs made in the 21st century have flat display panels because they use less power, look sleek, and are easy to use.
Curved TVs have slightly curved screens, but they aren't very different from flat TVs. They have a concave surface to make the experience of watching more "immersive". Companies like LG and Samsung put these TVs on the market in 2013. Today, only a small number of companies make curved screens because flat screens are better.
When choosing a television, it's important to consider features like smart capabilities, the number of inputs, and the refresh rate. Smart TVs can connect to your home network and use web apps, while multiple inputs allow you to connect all of your entertainment devices. Refresh rate is the number of times per second that a screen is updated with new images, and a higher refresh rate can result in smoother motion. With these factors in mind, you can find a TV that fits your needs and budget.
Most TVs sold today are "smart TVs", which means they can connect wirelessly to your home network and have special processors built in to use web apps. A smart TV lets people stream movies, play music, or even check their social networks. Many newer models even work with Google Assistant and Amazon Alexa, so you can use simple voice commands to take control. Smart TVs are always getting smarter, and new features are always on the way.
Enough inputs: If your entertainment system has a lot of parts, your new TV needs to have enough inputs to support them all. A typical home theatre system might include a Blu-ray player, cable box, receiver, streaming media player, and video game system.
Refresh Rate: A TV's refresh rate is how many times an image is shown on the screen every second. Most TVs have refresh rates of either 60 or 120 Hz, which means that the picture on the screen is updated 60 or 120 times per second.
Remotes: Your new TV will come with a remote that lets you use all of the controls and menus. Many companies sell remotes that can also be used to control other products they make e.g. the remote for your Samsung TV will likely be able to control your Samsung Blu-ray player or soundbar.
There are several brands of television available, most of which are stocked by MHC World:
