Which is more likely to hurt the eyes, desktop monitor or LCD monitor?

It hurts your eyes even more with an LCD screen!

According to a recent survey by the authoritative German computer magazine "Macwelt", although the radiation of liquid crystal displays is much smaller than that of ordinary displays, because of its high brightness, it is more likely to make our eyes tired, and may even cause symptoms such as headaches.

In the survey, the researchers tested 10 different brands of 19-inch LCD displays, both desktop and laptop. They found that all of the LCD screens tested had the problem of "too brightness". The researchers pointed out that when the brightness of the display reaches 100 cd per square meter, which is the unit of luminous intensity "kandela"), it already has a certain effect on the eyes.

The liquid crystal display they tested had a luminous intensity of more than 300cd per square meter, and some even reached 400cd-500cd.

Dr. Wei Haien, a German computer expert who led the survey, said that this problem exists not only in LCD computers, but also in LCD TVs. In order to increase the clarity, these LCD screens not only rely on the light pipe behind the screen to increase the brightness, but also generally use a special "polishing technology" to make the surface of the display look like a piece of glass, which looks very textured, and also improves the color contrast and saturation of the screen. However, it also reflects light like glass.

Especially when the light hits the screen, it increases the reflection of light. Consumers who use this kind of display can easily be "punctured" by the light and produce symptoms of tired eyes, which can also slowly cause health problems such as vision loss and headaches.

This has nothing to do with what kind of machine,It's mainly a display problem,The display is roughly divided into liquid crystal and flat 2 kinds,Of course, liquid crystal is better than pure flat in terms of eye protection,As for desktops and notebooks,If they are all LCD,Then the rest is just a matter of looking at the technical parameters of their display

Desktop hurts your eyes, if you want to buy it, it's good to buy LCD! ～～

I sue you. TV display, computer display, mobile phone display screen for a long time, damage to the eyes. So don't believe that. Fooled. Ad. The point is that you should pay attention to the reasonable use of time when using it.

It is only related to monitors, not desktops and laptops. Monitors generally do not have an energy-saving mode for desktops, while notebooks have an energy-saving mode. The energy-saving mode is generally harmful to the eyes.

But if you set the notebook to a non-energy-saving way, you're good to go. It mainly depends on the quality of the display!

Laptop screens are generally inferior to desktop screens, and in general, laptop screens hurt your eyes more.

The brightness should not be too high, it is not harmful to the eyes.

Laptops are all compressed. The screen is generally used as a defective product, and the color reproduction and effect are not as good as the display effect of desktop brand monitors. Although some laptops look and feel clearer than desktop screens, the gloss color is definitely not as good as desktop brand computers.

Desktops look much more comfortable. Of course, if you're an Apple computer or other notebook with excellent screen colors, then consider it differently.

It's all the same as liquid crystal, there's no difference, if the brightness is not suitable, it's still a problem that the adjustment is not in place.

Whether it's a desktop or a book, the brightness is not good for the eyes, and the brightness is average! The adjustment method is to adjust according to the sensitivity of your eyes, that is, how to look comfortable, how to adjust!

LCD screens have radiation, whether it is a computer or a TV, the radiation behind the screen is strong! This keyboard has radiation!

Discussion of which is harmful to the eyes between LCD monitors and watching ordinary CRT TV:

LCD monitors and ordinary picture tube TVs have the frequency problem of 'field, line' scanning: In particular, the field scanning frequency of analog color TV is 50Hz, that is, the TV screen turns on and off for 50 seconds, just like an incandescent bulb for 50 seconds, because of the inertia of the eyes, we are not easy to find. The frequency of the computer monitor is adjustable, and there is support for 60-120Hz display, which is generally adjusted to 85Hz for better use.

And this 'flickering' is certainly harmful, but the working principle of the display device must be supported by this frequency.

In addition, the use and adjustment of the current factors can not be ignored, otherwise it is also harmful to the eyes, but can be adjusted to the best:

1. The indoor contrast should be appropriate and not too strong, that is, not all black and sunlight, lights illuminating the screen, and using curtains and lighting;

2. Display contrast and brightness to suit the ambient brightness and brightness to suit your eyes

3. The brightness is 30% and the contrast ratio is 70%, which is moderate;

4. Adjust your sitting posture, it is better to look at the head-up monitor, and the LCD monitor is not good when you look at it from the side, and there is an 'angle' limit.

5. Distance from the monitor, depending on the size of the screen and personal eye condition, personal adjustment;

1. It is recommended to use CCFL backlight technology for many years, although CCFL does not have the low power consumption of LED, although CCFL does not have the brightness of LED, although CCFL does not have the high contrast of LED, but CCFL is much less harmful to human eyes than LED.

2. Although the IPS panel has an outstanding display effect, it is also the LCD panel that is the most harmful to the eyes. TN and VA panels cause little damage to the eyes. It is recommended that ordinary office, home, and programmer users choose the TN panel; Gaming, Movie, Graphic Design users choose the VA panel for better display.

3. There are 4 brands with the strongest display control circuit design strength, namely: Yizhuo, Iiyama, NEC, and Mitsubishi. These four are among the top in the field of professional display drawing; Therefore, it is important to have eye health on the computers that are commonly used.
