Whether a CRT monitor is more eyesight friendly than an LCD monitor

The cathode rays of CRT are very harmful to the human eye, while liquid crystals are almost harmless. The radiation of the display regardless of CRT and LCD front is very low, mainly concentrated on the side and back. If you are doing CAD, you need to use liquid crystal if you don't have high requirements for color, and if you are doing renderings, use CRT with color

No, the cathode rays of CRT are very harmful to the human eye, while liquid crystals are almost harmless.

The liquid crystal is much better for eyesight than the CRT one. Because there is no strobe.

Says who? Liquid crystal displays emit much less radiation than CRTs.

It's just that the display accuracy of CRT is higher than that of liquid crystal.

If you work with images a lot, it's recommended to choose CRT

The others are not much different either.

Just pay attention to it.

Rest your eyes for more This is the best way to protect yourself.

It's very simple: CRT has traveled a long road, so the display effect is better, but the radiation impact is a little higher, because the refresh rate problem will be uncomfortable for the eyes to see for a long time, and it is inconvenient to carry.

LCD radiation is small, there is no flickering problem, basically does not make the eyes tired, and it is easy to carry, but it is not a long walk, and the display effect is average.

LCD: **, short life, new technology, clear color, poor brightness, tail picture, small size, low power consumption, no radiation.

CRT: low price, long life, mature technology, clear color, good brightness, no tail in the picture, large volume, large power consumption, and radiation.

It is recommended that families who do not play games, or have small children choose LCD, game fans or do graphic design choose CRT.

1. Advantages.

CRT display: CRT flat display has the advantages of large viewing angle, no dead pixels, high color reproduction, uniform chromaticity, adjustable multi-resolution mode, extremely short response time, etc., which are difficult to exceed by LCD displays, and now CRT monitors are cheaper than LCD displays.

LCD Display: The body is thin and space-saving, compared with the bulkier CRT display, the LCD only needs one-third of the space of the former. It is a low-power consumption product that can achieve no heat at all (the main power consumption and heating part is in the backlight tube or LED), while the CRT display inevitably produces high temperature due to the imaging technology.

2. Disadvantages. CRT display: easy to flicker, the refresh rate of the CRT screen varies depending on the resolution, the number of colors, the higher the resolution, the lower the refresh rate. Generally speaking, the refresh rate of the screen should reach more than 75Hz, so that the human eye is not easy to feel the flicker of the screen.

LCD monitor: It is easy to produce image smearing (such as rapid shaking of the mouse pointer), which is due to the fact that ordinary LCD screens are mostly 60Hz (60 frames per second), while CRT is mostly 85Hz (85 frames per second). However, this problem mainly appeared in games when LCD was first popular (i.e., "screen tearing"), and has been basically solved since then, and if it still appears, it can be solved by "V-Sync".

1. CRT display has reached the highest level of development, so the room for further rise is very limited. In this way, the inherent shortcomings of this display become a disadvantage in its competition.

2. The size, weight and high power consumption of CRT are not in line with the current people's positive life concept. These deficiencies happen to be solved by LCD liquid crystal displays.

3. The LCD display is unanimously favored by people inside and outside the industry for its small size, thin body, light weight, low energy consumption and many other advantages. Therefore, this market was completely launched by LCD and became its world.

4. For users, the thinner LCD display can not only give a comfortable feeling visually, but also release more of their desktop space in the actual use effect, and get a more personal use environment.

5. CRT display is a kind of display that uses cathode ray tubes, and the current highest-level flat display has the advantages of large viewing angle, no dead pixels, high color reproduction, uniform chromaticity, adjustable multi-resolution mode, and extremely short response time.

6. LCD display is a kind of display that uses liquid crystal control transmittance technology to achieve color. For LCD monitors with stable images and no flicker, the refresh rate is not high but the image is relatively stable. The LCD display also uses the technical principle of liquid crystal to control the light transmittance of the base plate as a whole, so it is truly completely flat.

These advantages are also incomparable to CRT displays.

Advantages of liquid crystal display (LCD): 1. Thin, does not take up space. 2. No radiation, good for health.

3. No flicker, good for the eyes. 4. Low energy consumption, much smaller than CRT display, saving energy. 5. Completely flat, no visual deformation.

At present, there are still shortcomings of LCD displays: 1. There is a viewing angle, and the viewing range is smaller than that of CRT. 2. There is a response speed, which will produce a picture drag.

3. The color reproduction and realism are not as good as the CRT display. 4. The brightness is not as good as the CRT display. And the above points are reversed, which are the 5 disadvantages and 4 advantages of CRT displays.

However, with the continuous progress of manufacturing technology, LCD displays are getting better and better, and CRT displays will eventually be replaced by LCDs, which is the general trend. I still remember,When I was a child,When color TV first appeared,I often heard people say,Color TV is not good,It's good to hurt your eyes,It's better to be black and white,Don't hurt your eyes,Try not to watch color TV。 But how many of them still watch black-and-white TVs?

And the major manufacturers basically no longer produce black and white TVs. But at present, the life of the LCD display is still relatively short, generally only about five years, the principle of the LCD display is like an advertising light box, the LCD screen itself does not emit light, all rely on the back of the lamp to illuminate the screen, with the increase of time, the brightness of the lamp will become darker and darker, and finally do not glow, then it will be the end of its life! Due to the different principles, CRT monitors have a long lifespan and can generally be used for more than ten years!

Compared with CRT displays, LCD monitors have the following advantages: CRT monitors display brighter images and have higher contrast than LCD monitors.

The LCD monitor is slightly dim.

Disadvantages: CRT monitors are bulky and heavy. The LCD display is small in size and light in weight.

CRT displays are bright and dazzling. If you look closely at the screen, you will find that the screen is flickering and rippling, and it is easy for your eyes to get tired after using it for a long time.

The LCD display screen is stable and does not flicker, the backlight is independent, the brightness is low, and the damage to the eyes is small.

Pure flat (CRT) has much higher radiation than liquid crystal (LCD), and it does not hurt your eyes with LCD.

The LCD has a response delay, and the performance of the CRT is not as good as that of the game.

LCD looks more high-tech
