In order to understand which display is good for eyes, let’s first take a look at several types of monitors that are common on the market today, and make a comprehensive comparison of them while describing them.
ink screen (no stroboscopic, no blue light hazard)
If this kind of display device does not turn on the backlight, it will protect the eyes, and the device will save power, but the shortcomings are also obvious. Most of them are black and white, and the refresh rate is low. It can only be used to see text-like things.
If you have to have good colors, you can watch videos and play games, then forget it, the ink screen is not suitable, and the ink screen refreshes too fast, which will greatly affect the service life. It is really used to brush videos and play games, and it will be scrapped after a year. , including the ink screen display, too, is text-based.
Total reflection screen LCD display (no stroboscopic, no blue light hazard)
There is no mass production yet. Whether it is BOE, TCL or clearlink, they are still on concept advertisements. As for whether it protects the eyes or not, it depends on your layout of the ambient light. During the day, you can use the diffuse reflected sunlight by the window. It’s a little more troublesome at night.
According to past experience, it can be solved by the LED light bar at the top of the room. If the distance of the table lamp is too close, it will still hurt the eyes. The advantages of the total reflection display are obvious. It is an ordinary display and then relies on the reflected ambient light. The display screen is to protect the eyes, and then the refresh rate is high, and the color screen has the disadvantage of color deviation, the reflectivity is not as good as that of the ink screen, and the requirements for ambient light are higher. 15%, but the key is that you have no other choice, because only Fujitsu is the manufacturer in the market. Therefore, we can only adapt to its shortcomings.
At present, LED displays are mainly used for large or super-large screen displays, and are temporarily used less on small or micro screens. This is mainly due to technical barriers. Conventional small-pitch LED displays are usually P1.0-P2 .0, the price is already much more expensive than most LCD displays, but if you want a finer picture and the dot pitch of the display is below P1.0, then the price will double up. Therefore, for the time being, no LED manufacturer has mass-produced LED displays with extremely small pitches.
Generally used in outdoor large-screen advertising, we will not stare for a long time, but when passing by, we will be attracted, so relatively speaking, the LED display is quite good.
natural light display (no stroboscopic, no blue light hazard during the day, short-distance light hazard at night)
You may see some natural light displays on the e-commerce platform. In fact, the backlight and backlight panel of the ordinary display have been removed, but this can only be used during the day. It has to rely on strong light as the backlight.
single LCD projector (no stroboscopic, blue light hazard)
I bought a single LCD projector (no strobe) a few months ago. It has LED backlight. I tested it without protecting my eyes. After looking at it for a long time, my eyes get dry and I have a headache. The reason is nothing more than the blue light and the light distance is too short. After adding a layer of diffuser in front of the polarizer, the display effect of the screen was unexpectedly improved, and the brightness was also lower, but it was very uncomfortable to use for a long time (more than 2 hours), so I gave up. (Non-single LCD projectors may have stroboscopic hazards)
low blue light and no stroboscopic eye protection display (non-DC dimming has stroboscopic, blue light hazards, and short-distance light hazards)
Although manufacturers reduce blue light through LED materials, filters, color temperature, etc., but what about the light distance? Too short light distance will always hurt the eyes, and if you use it for a long time, you will be dizzy and unable to sleep. Healthy light is not only low in blue light, but also in light. The energy is also weakened by the spatial distance.
Summary: In fact, no matter what display is used for a long time, it will hurt the eyes, but some products are more harmful to the eyes, such as the low blue light eye protection display introduced at the end, if you want to do a good job For eye protection, it is still necessary to correct the habit of using eyes, and do not use the eyes excessively.
