Televisions is a tool or media that can broadcast sound and moving images, either in black and white or in color. Television is a group of media or communication tools that the public has widely owned.
Apart from the relatively cheap price of television currently circulating in the market, television can also attract viewers because it can present audio and moving images.
In contrast to radio, which only present sound, or newspaper, which only provide text and images on printed paper.
Along with the times, television now has several types of changes. Here are the seven types of TVs that are commonly sell on the market.
1. Tube Television
Tube television is a popular type of TV in the 2000s. This type of TV uses Cathode Ray Tube (CRT), so it can be said that tube TV is a type of television that still uses old technology.
Tube TV has a tube on the back that serves as a place for the screen and the projection. Later, the resulting image is an image that comes from electrons emitted through the projector.
TV tube usually has a large size and heavy so that it will take a lot of places. Moreover, the power used by tube TV is also quite immense compared to other types of TV.
But behind the shortcomings, tube TV has the advantage of a relatively low price. In addition, spare parts from tube TVs are cheap and easy to find.
Also, the view angle of the tube TV is better than other types of TV. Tube TV receptors are very good at receiving broadcasts, even in remote areas.
2. Plasma TV
Plasma TV is a type of television that uses plasma to produce images on the TV. Plasma is a kind of gas that can separate electrons from atomic nuclei. This type of TV consists of two pieces of glass with a mixture of gases in it.
The gas is collected and put in the plasma. When there is electricity, the gas will react and produce a pixel image on the screen. The advantage of Plasma TV is a good view angle like a tube TV. Also, the resulting image is more contrasted and clear. And the price is also relatively low.
The drawback is that the resulting image quality will decrease in a long time, so you are required to take better care of this type of television.
3. LCD TV
LCD TV (Liquid Crystal Display) is a type of television that the public has widely used. This type of TV contains liquid crystals. A liquid Crystal Display is a panel with a function to block or allow light to pass through.
The color brightness and the resulting contrast can be adjusted by increasing or decreasing the electric current. The liquid crystal does not have its light, so light is needed from outside to produce an image.
The screen design of this TV is flat, and this tv is also commonly used for computer screens. One of the advantages of this LCD TV is that it is pretty thin and light in weight.
This type of TV also only requires relatively low electrical power. Another plus is that the resulting image quality is better than tube TVs or plasma TVs.
The drawback is the view angle is not good, where the image quality decreases when viewed from a wider angle. In addition, the Refresh & Response Rate of this TV is lower than Tube TV & Plasma TV. And the price of this type of TV is generally higher when compared to tube and plasma TVs.
4. LED TV
LED TV is a television technology created from the development of previous television technology, namely LCD TV. So, LED TV is an upgrade from LCD TV.
However, the technology developed is not entirely derived from LCD TVs because there are still some differences. One of them is the backlight used. Previously, LCD TVs used fluorescent lamps for backlighting, while LED TVs used LED (Light Emitting Diodes) lamps.
The advantage of LED TVs is that they can save about 40 percent of energy compared to LCD TVs. In addition, this LED TV can also produce better images in terms of screen brightness and contrast. Also, LED TV is an environmentally friendly television because it does not contain mercury, which can pollute the environment.
The drawback is that the price offered is more expensive than the previous type of TV because it offers several advantages.
5. OLED TV
OLED TV (Organic Light Emitting Diode) is a type of television that comes from the development of LED TV. However, unlike LED TVs, to produce images, OLED TVs do not require a backlight.
OLED TVs also use materials such as organic carbon compounds with the help of LED lights, so they can produce images when an electric current flows.
In its development, OLED technology for TV is now working until it is called AMOLED (Active Matrix Organic Light Emitting Diode), which was initially a technology created for the needs of gadget screens.
Like LED TVs, OLED TVs also have the same advantages, such as thin and light designs. Also, OLED TVs have unlimited sizes, so they are usually mounted on the walls of buildings or malls.
The resulting images quality is also sharp and better than LED TVs. The drawbacks are the price of OLED TVs and expensive spare parts when there is damage to the OLED TV.
6. UHD TV
UHD (Ultra High Definition) TV is a type of TV that has a very sharp screen resolution, and the resulting image quality is outstanding. Ultra High Definition is a term for television with a size of 3840 x 2160.
The advantage of this TV is that the picture quality is better than other types of TVs so that it will spoil the eyes of the audience, and the size is also thin and light. On the other hand, the drawback is the same as OLED TVs, which are usually priced at a high price, more expensive than OLED TVs, of course.
7. Smart TV
A smart TV is a television that has the same technology and features as a smartphone. Some of the technologies are used for browsing, YouTube, video calls, and others. Besides, you can watch local broadcasts. With Smart TV, you can watch movies or foreign broadcasts.
However, to use the features built into Smart TV, you need to connect it with an internet connection.
Those are the seven types of TV that are currently on the market. When buying a television, choose the type of television that suits your needs.
