Computer vision syndrome is becoming a real threat to the vision of core computer display users. It comes with varying degrees of discomfort ranging from blurry vision to headaches. Expectedly, the addition to our mobile phones is at the forefront of this. Today the topic of discussion is smartphone LCD/OLED displays and your eyes. I want to critically analyze the difference between the two displays, the advantages of one over the other, the effects of phone display on your vision, and how you can minimize the strain.

Smartphone LCD/OLED displays And Your Eyes
The mobile phone is so important to us that there is nothing to replace it with. So, we eat and play mobile phones, walk and play mobile phones, and won’t go to the toilet without it. Lying down to play, sitting and playing, falling asleep, and lingering on the phone.
The long-term consequence is that vision is becoming more and more blurred. Some people can no longer distinguish between people and livestock within ten meters. Even a small partner who regularly eats chickens plays a few games, and the whole person will be “airsick”.
Vision problems such as CVS are not unrelated to the screen of our mobile phones. It may be that when people pick a mobile phone, the quality of color and cost will grab more attention. However, the importance of the screen cannot be ignored.
To protect eyesight from the revolution, mobile phones display technology experts chose two types of screens. The OLED and the LCD.
Defining Mobile phones’ OLED & LCD Display technology.
What are the OLED screens in the flagship machines released by major mobile phone brands? Which are LCD screens?
- Apple: iPhone X is an OLED screen. Previous models were all LCD screens.
- Samsung: S7, S8, Note 8, and S9+ are very much OLED. After all, the OLED screen is Samsung’s home.
- Huawei: Huawei P20 Pro is an OLED screen, P20 is an LCD screen
- OPPO: OPPO R15 is an OLED screen
- Millet: Millet MIX 2S has an LCD screen
- One plus: One plus six has an OLED screen

As can be seen from the above list, Samsung, Apple, and Huawei have chosen OLED as the standard for their flagship phones; it is imperative that mobile phone screens focus on OLEDs.
Are OLED Smartphones Better than LCDs?
OLED and LCD screen structure comparison
The LCD screen is believed to be no stranger to everyone; mature technology and service life make it the most secure choice for most mobile phone brands. However, from the structural point of view, LCD panels that require backlight support are much more complicated.
By contrast, self-luminous OLED screens are simple and lightweight, with smaller thicknesses and flexible characteristics, making them more suitable for small wearable and curved screen devices.
Compare The Advantages and Disadvantages of OLED Screens With That Of LCD
1. Contrast
OLED screen benefits from its own light-emitting diodes advantages. Showing black is more extreme, with color domain and wide viewing angle characteristics. While the LCD itself does not shine, the screen is illuminated by the LED lights behind the screen can be achieved. Lights up when dark.
2. Afterglow, power consumption
Since the OLED saves the backlight group structure of the LCD and the pixels do not emit light when the display is black, the OLED saves more power under the same conditions of use. In addition, due to the self-luminous characteristics, the backlight of the OLED screen has less afterglow and is generally less dazzling under the same brightness.
3 smartphones LCD/OLED displays and your eyes: anti-shock, low-temperature performance
Compared to the LCD, the OLED screen is a non-vacuum all-solid-state device. By extension, the anti-vibration and low-temperature resistance (still at 40 degrees Celsius can work normally) characteristically, OLED is more excellent.
4. Burning screen and service life
At this point, LCD is better than OLED. The LCD screen does not emit light, and its low power consumption control characteristics make its life longer than that of OLEDs. As a self-illuminating, the OLED screen has severely limited its widespread use due to the screen life caused by screen aging.
It can be said that each has advantages and disadvantages. If we only protect the eyesight, macroscopically speaking, the OLED screen is still better than the LCD screen. Otherwise, it may not be attracted to competing brands. Although there are more finely divided LCD screens (TN panel, VA panel, and IPS panel), OLEDs are uniquely superior in performance, and they have become the trend of mobile screens with a more perfect visual experience on the mobile phone screen.
How can you reduce eye fatigue while using your Smartphone?
Improve “airsickness”, what are the few measures that can alleviate eye fatigue?
Before you use your phone in a dark environment, be sure to lower the screen brightness and turn on the phone’s night mode.
Apple’s mobile phone can also open the Night Shift function when the screen is turned down to a minimum.
For Android phones, you can set the power saving mode in the mobile phone home so that the phone can automatically reduce the screen brightness according to the external light.
Eyes exercise that can ease eye fatigue resulting from extensive mobile phone use.
Stare into the distance.
Find a grass or green tree 10 meters away. There is no open grass around. You can choose a picture with a wide field of vision. Because green has a short wavelength, imaging in front of the retina promotes eye relaxation. Also, eye ciliary muscle relaxation reduces eye fatigue. Don’t blink your eyes, and don’t always blink your eyes. Eliminate distractions, and concentrate on your gaze for 25 seconds to identify the contours of grass or leaves.
Then place the left palm slightly above 30 cm in front of the eyes, and look at palm lines from head to tail one by one for about 5 seconds. After reading the palm prints, gaze at the distant grass or leaves for 25 seconds, then look at the palm prints again. Repeat 20 times in 10 minutes, three times a day, and increase the number of training if the visual acuity is severe.
2. Crystal Gymnastics
You need to do this with both hands propped up. Let the eyeball turn 10 times in the order of upper, lower, left, and right, and then rotate counterclockwise and clockwise 10 times. Find a scene 3 meters away (such as wall paintings, etc.), while lifting your left hand slightly higher than the eyes straightened (about 30 cm), see the palm of the hand pattern, and then see the Qingyuan, try to move between the two, round-trip 20 times Quickly.
3. Ironing method
This method is best to sit, relax, close your eyes, then quickly rub the two palms, make it hot, and cover your eyes with both hands, hot after the two hands suddenly took off, both eyes also at the same time, Such 3 to 5 times, can promote eye blood circulation, increase metabolism.
