Many mobile phone manufacturers today use OLED (Organic Light Emitting Diode) displays. Compared with LCD screens, OLED screens have a variety of advantages. For example faster refresh rates, better color saturation and virtual contrast, less power consumption, and longer service life.
In the past two years, smartphones with OLED displays from Apple's iPhone X to Samsung's Galaxy Note 8 have been brought into the market one after another.
In fact, this technology only improved in 2015. Before 2015, the screen that uses OLED does not last as long as the screen that uses LED (light-emitting diodes), normally 30,000 hours.
Benefits of OLED technology
OLED technology has obvious advantages over traditional LCD（liquid crystal）screen technology. OLED screen thickness can be controlled within 1mm, while LCD screen thickness is usually about 3mm. And the OLED screen is lighter than the LCD screen.
The liquid structure of the OLED screen guarantees the anti-decay performance of the screen and has a wide viewing angle which the LCD screen does not have. This can allow him to see the same screen over a very large area. Also, the images have no distortion.
Its response time is one-thousandth of the LCD screen. And the low-temperature-resistant OLED screen can work normally in an environment of -40℃. Then the screen that uses the OLED can be transformed into a curved screen, like casting a spell on the phone screen to people.
What is a burnt phone screen?
Screen burn is a phenomenon that a fixed image is displayed for a long time in a screen, the screen leaves an imprint of this image. Nevertheless, this imprint cannot be removed. This phenomenon normally happened to the OLED screen or plasma televisions.
And it leaves an imprint of the image on the screen, which affects sending and receiving messages, watching videos, etc.
It is only a solution to replace the screen, but the original screen is very expensive. So we should avoid the screen burn phenomenon.
How to avoid or mitigate this burnt screen phenomenon
1. Set the lock screen time:
A still image is displayed for a long time on a screen, which causes screen burn-in. We set lock screen time to let your phone screen rest in time. It can protect your screen and save power.
2. Change wallpaper frequently:
The most displayed image in mobile phone use is the mobile phone wallpaper. In order to avoid burning the screen, one should often change the phone wallpaper. The best wallpaper is dark-toned wallpapers and live wallpapers.
3. Enable the automatic brightness adjustment function:
The sensors of the smartphone will automatically adjust the brightness of the screen according to the phone's ambient lighting conditions. It can avoid unnecessary brightness, protect your eyes and extend your battery life.
4. Turn off adaptive backlight:
You choose a phone with the display setting of adaptive brightness function. Phones like Honor foldable phone, iphone 13, OnePlus 9 pro, etc. have the automatic brightness adjustment function, which can protect the mobile phone from screen burned.
5. Don't hold the power button to open an application for a long time:
Many people think that it is necessary to press the power button several times before opening other applications after using an app. This will cause flickering and lead to screen burn-in. So we shouldn't press the power button too long when we use OLED screens.
This article is a guideline for those who want to make OLED screen phones last longer. Hope it will help many people, especially those who have been using OLED phones.
