Everyone knows that OLED screen has a fatal flaw is easy to burn screen, so when iPhone X was first determined to use OLED screen, many of my friends are skeptical. So now iPhone X also listed for two months, it is in the prevention of burning screen this thing done how to do? Korean media Cetizen brought us the iPhone X, Samsung Note 8 and Samsung S7 Edge screen burn test comparison.
In Cetizen's test, the screen lit up for 510 hours, and the iPhone X's screen did not show any visible burn-in until 510 hours of on time.
During the test, the Cetizen looked at the screen every other time, and both Samsung phones were burned early. The latest Samsung Note 8 is the worst model to burn a screen, and this should be due to its super brightness. The maximum brightness of the screen is more than 1000nit. The S7 Edge is only 500nit.
Some friends may not know much about burn-in. OLEDs use organic materials to make them bendable. However, OLEDs also have the disadvantage of being less stable. When one pixel displays the same color for a long time, the pixel particles will Aging causes the residual image of the original image to appear for a long period of time while other contents are displayed in the future (note the photo interface below), and the process is irreversible. Therefore, we usually use the equipped OLED mobile phone, try to avoid turning on the maximum brightness and long time to display the same image.
In order to solve this problem, Samsung has added a pixel drifting method to the system. That is to say, a pattern displayed for a long time such as a virtual key is offset by a few pixels after a certain period of time to prevent the same pixel from working for a long time. However, Efforts are also limited to this, for third-party App fixed color blocks and buttons and did not burn screen optimization. In addition, Apple also added a pixel drift mechanism to the iPhone X system, but in addition, Apple obviously has other know-how to prevent screen burn-in, making the X-screen of the iPhone X outperforming the blue.In fact, this test to make Xiaobian think of Sony, before Sony's CMOS other people are using very well, but Sony itself is bad tuning. Do not know if this is the Samsung itself or Apple did too good?
