What are the advantages of LCD monitors? What are the advantages and disadvantages of LCD screens?

No radiation. The only plus.

There are a lot of disadvantages. Not as good as a flat one.

Advantages of liquid crystal display (LCD): First, it is thin and does not take up space. Second, there is no radiation, which is good for health.

Three, no flicker, good for the eyes. Fourth, the energy consumption is small, much smaller than the CRT display, saving energy. Fifth, it is completely flat and has no visual distortion.

At present, there are still disadvantages of LCD displays: First, there is a viewing angle, and the viewing range is smaller than that of CRT. Second, there is a response speed, which will produce a picture drag.

The advantages and disadvantages of LCD liquid crystal displays are actually unclear only this content, so I sorted it out in a general way;

Because compared with traditional displays, the display principle of LCD liquid crystal displays is very different. Compared with traditional displays, LCD displays inherently have the following absolute advantages:

1. Zero radiation, low energy consumption, low heat dissipation.

2. Slim and lightweight.

3. Accurately restore the image.

4. The display characters are sharp. The picture is stable and flicker-free.

5. The screen is easy to adjust.

With these natural advantages of liquid crystal display, Shenzhen Bar Intelligence has applied it in the bar commercial display, and through technical means to integrate with it, the product has been successfully applied to all walks of life in the city.

However, compared with the traditional display screen, the manufacturing cost of the LCD is limited, and the current LCD display is still relatively high, but compared with the value it generates, this can not be completely regarded as a disadvantage.

Thin, does not take up space. No radiation, good for health. No flicker, good for the eyes.

The advantage of LCD screens is that they protect the eyes. Prevent eye punctures from light.

It is clear that the screen is also very large, and the disadvantage is that it is easy to break.

Problem description: Is it specific Okay Please, masters.

Analysis: 1, in fact, the biggest advantage of LCD compared with traditional CRT is the power consumption and volume, for traditional CRT, its power consumption is almost 80W, and most of the power consumption of liquid crystal is up and down 40W, so calculated, LCD has obvious advantages in energy saving.

2. Compared with the traditional CRT, the liquid crystal also performs in environmental protection, because there is no high-voltage component like the CRT inside the liquid crystal display, so it will not exceed the X-ray standard due to high voltage, so its radiation index is generally lower than that of CRT.

3. Because the CRT display relies on the electromagnetic field generated by the deflection coil to control the electron beam, and because the electron beam cannot be absolutely positioned on the screen, the CRT display often has different degrees of geometric distortion and linear distortion. The LCD will not have any geometric distortion and linear distortion due to its principle, which is also a major advantage.

Disadvantage 1: The visual deflection angle is too small. The LCD display has a limited visual deflection angle, and it is often only from the front**, and there will be large brightness and color distortion when viewed from the side.

Now the LCD display on the market has a visual deflection angle of about 140 degrees, which is enough for personal use, but if several people are ** at the same time, the problem of distortion will appear.

Disadvantage 2: It is easy to produce image tailing. The response time is fast enough to ensure a coherent picture.

This is important when playing games and watching fast-action footage. At present, the response time of the general LCD display on the market has made a great breakthrough compared with before, generally about 40ms. However, the response time of some LCD products is not short enough, resulting in the phenomenon of image smearing when displaying moving images.

Disadvantage three: The brightness and contrast of the LCD display are not very good. Since liquid crystal molecules cannot emit light on their own, liquid crystal displays need to rely on external light sources to assist in emitting light.

Generally speaking, 140 lumens per square meter is sufficient. There is still a gap between the parameter standards of some manufacturers and the actual standards.

Disadvantage 4: LCD "dead pixels" problem. The material of the LCD screen is generally glass, which is easy to break, and each pixel is very small, which often causes individual pixels to be broken, commonly known as "bad pixels", which cannot be repaired, only to replace the entire display screen, and the replacement is often very expensive.

Disadvantage five: limited lifespan. LCD monitors are not as durable as regular monitors. It is generally considered that two to three years is a normal lifespan, so when buying, you should consider whether you are willing to replace the monitor again after two or three years.

In general, the advantages of traditional CRT displays in terms of color and fast image display are obvious, while the advantages of LCD in terms of shape, radiation-free, flicker-free and other aspects are also outstanding. Radish and cabbage have their own loves, and what kind of display products to buy depends on your specific needs.

Advantages of a well-branded monitor:

1. The quality of the screen is guaranteed;

2. After-sales guarantee;

3 Bright colors.

Ophthalmologists also believe that Xiangkong LCD screen is more conducive to protecting eyesight. "The refresh rate is at least higher than 85 Hz l seconds to be comfortable for the human eye to open, that is to say, the image has to flicker more than 85 times per second, and it is precisely because of the low refresh rate that ordinary displays will cause eye fatigue," Dr. Wang Wujun explained. ”

The difference between LCD screen and LCD screen is that the LCD screen is only a component, and the LCD screen is also called LCD module professionally, which refers to the display component used on the LCD screen or other instruments, and the picture tube in the CRT display is the same status. An LCD monitor is a display made of a lot of circuits around the LCD screen. LCD screens can be as small as 1 inch (for calculators) and as large as 65 inches (SHARP LCD TVs can be mass-produced), and can be mounted on electronic devices such as calculators, digital cameras or camcorders, or can be used as computer monitors or LCD TV displays, as long as there is a corresponding hardware circuit to support it.

The specific**is determined according to the size and performance of the screen,**often very different, I don't know what kind of screen you need, so I can't give you specific**. But it shouldn't be useful if you need a screen alone.,Just a screen can't play a display role.,It must be supported by hardware circuits.。

Like Sharp's best screen now, it can achieve 2 million pixels on a 7-inch area, which is unique. The general monitor or TV screen is about one million pixels.
