What brand is good for a 50 inch LCD TV?

It's all a bunch of laymen.

First of all, LCD is the same as LED and screen, but the backlight is different. The LCD uses a CCFL cold aurora tube, so the appearance is thicker, and the LED uses a light-emitting diode, so it is thinner and more power-efficient.

The world's professional production of LCD screens is Sharp, known as the father of liquid crystal, and the LCD screen was invented by Sharp. The LCD screen is only 52 inches, not 50 inches. LCD can buy Sharp.

Now LCD manufacturers have been clearing, ** will be cheaper, if you don't care much about the appearance, now buy an LCD is very cost-effective, the same look.

Secondly, PDP is plasma, high power consumption, low brightness, high dynamic contrast, that is, high refresh frequency, but the picture graininess is more obvious than that of the LCD screen, and ordinary signal sources at home cannot be seen. And the surface of the plasma TV is glass,If the indoor light is strong, the reflection is more obvious,Can't see clearly。

Now only Panasonic and Changhong produce PDP plasma, and Samsung has been doing it recently, but it is higher.

To sum up, choose for yourself.

High resolution is not necessarily clear,50Inch Panasonic,Changhong is doing,Samsung's 51 inches are also good,The key is to look at the color and sound quality Personally recommend Samsung We in this factory in 2001 with Samsung50Inch TV for monitoring Basically, open more than 20 hours a day There has been no problem at all。

50Inch TV length is about 111 cm,Width is about 62 cm,Normal50Inch LCD TV screen ratio is16:9,50Inch corresponds to the diagonal hypotenuse length,So according to the proportional matching and Pythagorean theorem,The screen length of the Pepitan 50-inch LCD TV is about 111 cm,The width of the screen is about 62 cm,So the specific size is meters。

LCD TV size calculation method:

Take a 32-inch LCD TV as an example: 1 inch = centimeter, calculated by the diagonal of the TV plane: 32 times centimeter, according to the common 4:

3 is a proportional calculation, generally length =, width =; If calculated according to the ratio of 16:9, it is generally 69=cm, and width=39cm.

The 50-inch diagonal is centimeters long, and there are two aspect ratios, 16:9 centimeters on the long side and 62 centimeters on the short side; The long side of 4:3 is 7707 cm long, and the short side is 7707 cm long.

In fact50The size of the LCD TV is already very large,It is recommended to place it in the living room of a large apartment,If the living room is not very large,But such a large LCD TV is placed,It often gives people a very incongruous feeling。

When choosing a 50-inch and 55-inch TV, there are several factors to consider:

1.Viewing distance: The viewing distance of the TV refers to the distance between the TV and the TV screen, which affects the experience and comfort.

Generally speaking,50The corresponding viewing distance of the inch TV is about meters,55The corresponding viewing distance of the inch TV is about meters。 If you're far away, you can choose a 55-inch TV, and if you're closer, you can choose a 50-inch TV.

2.Budget: A 55-inch TV will be higher than a 50-inch TV**, so you need to consider whether it is worth investing in according to your personal budget.

3.Space: If you have a smaller home, a 50-inch TV may be more suitable, while if you have a larger space, you can opt for a 55-inch TV.

4.Resolution: With the continuous update of TV technology, the resolution is also improving, generally speaking, the resolution of 55-inch TVs is higher than that of 50-inch TVs, such as 4K, etc.

5.Preference: The final choice of 50-inch or 55-inch TV also depends on your personal preferences and needs.

In general,50Inch and 55Inch TVs will differ in terms of viewing distance、Budget、Space、Resolution, and personal preference,It is recommended to choose according to individual circumstances,Also pay attention to brand、Quality、After-sales service and other considerations。

Personally, I feel that the 55-inch one will be a little better, first of all, the size is large, it looks clear and comfortable, there is an immersive feeling, and secondly, it looks atmospheric. But which one is better depends on the size and layout of the room.

In fact, there is really not much difference between the same brand, and there is not much difference between 50 and 55.

The length of the 50-inch LCD TV is about 80 centimeters long. The diagonal is about 135 cm.

The size of the TV screen is not named after the length and width of the TV, but after the length of the diagonal macro line of the screen. A 50-inch LCD TV means that the diagonal of the screen is 52 inches;

That's 52 centimeters when converted to centimeters. 50-inch display width and height of a few centimeters 16:9 LCD panel, its screen width is about 135cm wide, height is 80cm, but with the outer frame is not necessarily.

Maintenance Tips:

Try not to let the LCD TV work for too long or continue to display the same picture. Because the screen of the LCD TV is displayed by LCD pixels to form a picture, the LCD TV works for a long time, or the LCD TV is always displayed with lead to disturbance of the picture, which will overheat the LCD light-emitting tube and cause internal burnout;

When the user is not watching TV, he should turn off the monitor or turn down the brightness of the monitor in time. Users should try not to press the pause button while enjoying a CD to keep the screen displayed.

Avoid impacting the screen, because the LCD screen is very fragile, to avoid strong shocks and vibrations, the user reminds children not to practice the impact of the live Huai Dan movement in front of the TV.
