If you plan to buy a TV in the near future, then this TV buying guide is exactly what you need. It comprehensively describes the existing TV types, advantages and disadvantages, and purchase recommendations, and I believe it can help you very well.
What types of TVs are there in the market?
Perhaps we will see many TV manufacturers write a lot of fancy names on the introduction page, but in fact, there are only 3 types at present, LCD, OLED and LED. The three types have different application fields and groups, which is why the three types of TVs each occupy a good market share. Let’s take a look at their advantages and disadvantages.
LCD TV advantages
- Affordable price
- The screen size is conventional 16:9, 21:9 and 32:9
- High refresh rate, good gaming effect
- Anti-glare
SHARP LCD TVDisadvantages of LCD TV
- High energy consumption
- Insufficient purity of black tone
- Shorter service life than OLED and LED
- Brightness and contrast are much worse than the same type of OLED and LED TVs
The viewing angle of the screen is limited, and the screen image will be distorted in the blind spot area
Advantages of OLED TV
- High brightness and high contrast
- Accurate color value
- Self-luminescence is more energy-saving
- No blind spot area
- The fastest response time
4K OLED TVDisadvantages of OLED TV
- Fewer brands to choose from
- Small screen size
- There is a risk of screen burn-in
- The most expensive of the three types of TVs on OLED TV
Advantages of LED TV
- High brightness and high contrast
- Can be spliced in any size
- Long service life
- Can be arbitrarily matched with various devices for additional expansion
JYLED LED TVDisadvantages of LED TV
- Cannot be made into a screen that is too small
- LED TV has a long viewing distance and requires a large space
- LED TV usually needs to be spliced with LED panel tiles, which requires a certain degree of hands-on ability
Which type of TV should you choose?
Generally speaking, LCD TV is the most economical, and there are many brands and sizes available on the market. If the requirements for picture quality are not too demanding, LCD TVs can be given priority.
OLED TVs are still at a relatively high price at present, and the screen is not as large as LCD TVs and LED TVs. But for people who want to experience better picture quality, OLED TVs are also a good choice.
LED TVs, also known as LED video wall TVs, are made by splicing LED modules. The construction steps are relatively cumbersome, and the price of the screen fluctuates greatly depending on the selected model. In terms of the same distance and clarity, the price of LED TVs is comparable to that of OLED TVs, but if it is viewed at a longer distance, the advantage is very obvious, so it is suitable for people with larger houses and stronger economic strength.
What size TV should you buy?
Perhaps some people think that the larger the screen, the better the experience and the better the feeling. Of course, this is indeed one aspect, but the other aspect is that the larger the size of the TV screen, the higher its price. And if the screen is too large, it may require a longer viewing distance, which means you need to buy a large house. In other words, the larger the TV screen you buy, the more corresponding supporting expenses.
We observed the sales rankings of e-commerce platforms and found that the most popular TV screen sizes on the market are mainly: 55 inches, 65 inches, 75 inches and above.
55-inch TV
55 inches is a very clever TV size. It will not affect the viewing effect because of its small size, nor will it take up too much space because of its large size. Especially when used in a 50-square-meter living room, a 55-inch TV usually allows viewers to move around and watch comfortably at different angles.
Among the many TV sizes, the 55-inch TV has the highest cost-effectiveness and application range. It covers functions such as watching TV series, movies, and interactive games, so it is more easily accepted by consumers.
65-inch TV
For people who like larger and wider TV screens, a 65-inch TV may be a better choice. 65-inch TVs can often show more details than 55 inches, and with the improvement of TV technology, 65-inch TVs are usually not much more expensive than 55-inch TVs. The only thing you need to consider is whether the size of the entire space is large enough to accommodate a 65-inch TV.
75 inches and above
This is a good choice for people who have enough space and want to experience the cinema version. It is worth noting that because the size of a 75-inch TV is not only very large, but also very heavy, you usually need 3–5 people to cooperate in the installation. Once again, don’t try to install such a large screen by yourself, if you accidentally break it, it will not be worth it!
How to choose the resolution of the TV screen?
Modern TVs usually have FHD, 4K UHD and 8K UHD versions. The current mainstream TV screen resolution is mainly 4K UHD, and there are relatively few TVs with lower or higher resolutions. So, do you know the difference between TV screens with different resolutions?
In fact, this is easy to understand. Whether it is full HD, 4K, or 8K, their resolution is actually the pixels on the screen. For example, Full HD is composed of 1,920 x 1,080 pixels, with a total of 2,073,600 pixels, while 4K UHD is composed of 3,840 x 2,160 pixels, with a total of 8,294,400 pixels.
When we divide 8,294,400 by 2,073,600, we get the number 4, so the number of pixels on a 4K TV screen is four times that of a Full HD TV screen. By analogy, we can conclude that the number of pixels on an 8K TV is four times that of a 4K TV and 16 times that of a Full HD TV.
If we watch with the naked eye, we cannot distinguish the difference between 4K and 8K very well. Only when we zoom in on a part can we see the difference. Generally speaking, if you zoom in several times or watch it at a close distance, you will see significantly different results when watching it on a 4K or 8K screen.
It is worth mentioning that there are very few videos with 8K quality at present. If it is not necessary, it is more cost-effective to choose 4K. The main reason why there are too few 8K quality videos is that the transmission bandwidth is too low.
The current global transmission bandwidth is probably lower than most people think. Taking China, where the Internet is very developed, as an example, the current transmission bandwidth of most households is less than 5 megabits per second (even less than 2 megabits per second in some areas), which means that when we want to transmit a 110G 8K quality movie with a duration of only 2 hours, if we use a bandwidth of 5 megabits per second, it will take about 6.26 hours, which is much longer than the duration of the movie itself. Of course, this is just an estimate for concreteness. The actual size of 8K movies is much larger than the rough estimate, and the bandwidth is much smaller than the estimate.
