In recent years, some high-end brands have used OLED screens. With the continuous upgrading of technology, OLED screen technology has become more mature. Let’s take a look at why high-end mobile phones like to use OLED.

 

First of all, why do mobile phone manufacturers use OLED?

 

This is because OLED has low power consumption, high contrast, high response time, brilliant colors, good viewing effect, ultra-light and thin, and the most important factor is that it can be made into a curved or folded form, so under the vigorous promotion of SS, especially Apple After the use of OLED screens, it broke out completely. Now that SS is leading the OLED field, it is full of money, which can be described as scheming. Looking at the current mobile phone market, the flagship phones are almost all OLED screens, including forms such as four bends, punch holes, waterfalls, etc., not to mention folding machines that are in short supply in the market. These are all showing the advantages of OLEDs that can be used as curved screens. The incisive and vivid.

 

Next, does OLED hurt your eyes?

Everyone said that the OLED screen hurts the eyes because of the dimming method of the screen. Because the OLED screen is self-luminous, it uses the PWM dimming method (see the figure below), which means that the pixels are continuously switched on and off. Because this method will cause the so-called splash screen, there will be a saying that it hurts the eyes. If the frequency is fast enough, the human eye cannot distinguish it.

 

It is generally considered that the flicker frequency is higher than 1250Hz to be considered healthy, but the current frequency is not up to this standard, so it is best not to stare at the phone for a long time, especially in the dark environment, the screen flicker is lower and the damage to the eyes is more severe. Although there have been many improvement measures, including the improvement of dimming modes, they have not yet reached the above standards.

 

 

Therefore, as consumers, we have to relax a little while using mobile phones. Use your mobile phone in a planned way! Especially those who like to chase dramas and play games should pay more attention! After a long period, you can take a break and do eye exercises. In addition, the brightness of the mobile phone can be adjusted appropriately for different environments and scenes. Don't make your eyes look too hard. For example, you must adjust the corresponding brightness when using your mobile phone indoors and outdoors! Of course, most mobile phones can now be set to intelligently adjust the positive brightness!

 

Friends who use OLED screen phones protect their eyes while protecting their eyes! It is also very important to protect the screen of your favorite phone. The precautions are as follows:

 

1. The software icons we downloaded occasionally change positions! If you don’t change the position, it will take a long time. The phone screen will have an icon shape similar to a watermark! The icon keeps burning in the same position for a long time!

2、Don’t change the wallpaper too bright occasionally! The reason is similar to the icon!

3、It’s best to stick a screen protector too! Prevent physical damage! Because the cost of replacing an OLED screen is very high!

Too low brightness can easily cause eye discomfort. Mobile OLED screens can improve eye comfort by turning on the eye protection mode, adjusting the color of the screen, and increasing the brightness of the screen a little bit.
