In Guangzhou, a female student’s phone screen got burned due to playing the same video continuously for six hours. This incident made it to the top of Baidu’s hot searches on February 14th.
According to a video released by the Yangcheng Evening News on February 13th, Ms. Guo forgot to turn off the standby phone screen while she was out during the day. When she returned home at night and scrolled through her phone, she noticed traces of the video on the screen, “Those three lines of text were really clear, just like a watermark.”
Ms. Guo expressed, “I was extremely panicked at that moment.”
Regarding this phenomenon, the video explained that OLED screens are composed of many pixels, each pixel emitting light independently. If a few pixels stay lit continuously, the screen will age rapidly and leave residual images.
After the video was released, some netizens commented that it was a case of screen burn-in on the phone.
The official account of Beijing Wuli Network Technology Co., Ltd., “Happy Life,” explained that screen burn-in, also known as screen burn, refers to the phenomenon of permanent image retention on the phone screen. This phenomenon is usually caused by displaying static images or high-contrast, high-brightness content for long periods.
The reasons for screen burn-in can be attributed to several factors: firstly, most modern smartphones use OLED or AMOLED technology for their screens. Each pixel on these screens can emit light independently. When a specific area of the screen displays the same color or pattern for a long time, the pixels in that area age due to continuous illumination, resulting in decreased brightness or color distortion, leading to screen burn-in.
Secondly, prolonged use of high brightness or high contrast display settings can also accelerate screen aging. Under high contrast settings, there will be greater differences between light and dark on the screen, causing some pixels to bear a heavier workload and accelerate aging.
Moreover, if users frequently keep the phone displaying the same interface or application for extended periods, especially those with fixed elements such as the navigation bar, status bar, etc., these fixed elements are likely to leave permanent marks on the screen.
So, how can one prevent screen burn-in? “Happy Life” suggests users take preventive measures such as changing wallpapers regularly, using dynamic wallpapers or screen protection programs, avoiding prolonged use of high brightness or high contrast settings, and refraining from letting the phone display the same interface or application for long periods.
