OLED筆電到底多久會燒屏？ 兩個月實測告訴你答案！ | 笔吧评测室

Notebooks that mention OLED screens What do you think of in the first place? Yes, I believe many people's reactions are "Burning screen" OLED on mobile phones has been popular for many years Everyone is normal And the OLED screen of the notebook It was only in these two years that large-scale distribution began Coupled with the Windows UI and mainstream usage habits, it is easy to burn the screen It is normal for everyone to worry But all along Few people can make it clear How long will the OLED laptop burn the screen And to what extent it will burn To find out the answer to this question It took us two months A total of 5 OLED notebooks were used Completed this costly test I hope everyone can give me a free compliment We'll start right away First, introduce the test conditions In order to avoid the suspicion of intentional blackout, We will not disclose the brand model of this test machine But the panels used in the machine are all like this This is a Samsung 15.6-inch OLED panel It is more common on laptops at mainstream prices It is still a slightly old E4 luminous material It is well known The Speed and Use Time of OLED Screen Burning The color manufacturer optimization of brightness display is closely related to many aspects This experiment We simulated two scenarios The brightness of one set is pulled to the highest level (about 400nit) Reloaded win11 Pure Edition to remove all vendor optimizations And use the Windows default light color mode Corresponding to the more extreme situation The other is to turn down the brightness to 300nit This is also the brightness commonly used in bright rooms The machine defaults to the original system Keep the manufacturer's own optimization settings (such as pixel offset compensation) and dark color mode Corresponds to the daily use conditions of most people The picture of the test is divided into several parts In the upper left corner are shortcuts to some commonly used software At the bottom left is the local video played in a loop On the right side are four solid color blocks of RGBW At the bottom is an unhidden status bar In addition, we also ran a script Let it make keyboard input every 30 seconds This prevents triggering automatic screen rest or screen saver Finally, we set up the two computers Burn for 30 days without interruption for 7 × 24 hours What will be the final result? I'll see you next month 30 days have passed Let's look at Unit 1 first That is, the pure version system + the one with the highest brightness The most obvious place to burn the screen is obviously the taskbar This is always a white highlighted area in the test Now there is a dark mark If you look closely, You can barely distinguish the icons fixed on the taskbar Another relatively obvious place Is a shortcut to the upper left corner of the screen The most conspicuous thing is NetEase Cloud It's easier to see if you move In addition, the pure green Xbox icon also has a little trace But apart from these two places, The burning screen in other areas is very weak Basically can't see it And Even Netease cloud and taskbar are obvious places If you don't shoot with a gray background, In fact, it is not easy to find Anyway, I think only in the case of 30 days There is indeed a burning screen But it basically does not affect the use Let's take a look at the original system Unit 2 with brightness of 300nit Arguably The original factory system will be optimized And the brightness is also low The burning screen should be lighter But the result was somewhat unexpected Machine 2 is the one with more obvious burning screen First of all, we can see that There is an obvious dimming in the green block on the right side of the screen This phenomenon is very slight on Flight 1 Then the Netease cloud icon in the upper left corner It's also the mark of machine 2. It's a little heavier However, because the original system uses a dark taskbar, Therefore, the burning screen at the bottom of the desktop is lighter than that of the No.1 machine Of course, if you look carefully, you can still find it Anyway, this result gives me a very abnormal feeling The original factory system and low brightness actually became negative optimization There is no way to confirm whether it is an individual difference or something else Generally, when we mention OLED burning screen, Will feel that the aging of pixels is irreversible But is it really completely irreversible? We tried to turn off two computers and put them away for a day Re-shoot Unexpectedly, Both of them have greatly reduced their screen burning The solid color block of machine 2 is not so obvious On both computers, the taskbar and the icon in the upper left corner were almost completely restored Under normal use, almost no abnormality can be seen That is to say The phenomenon of OLED screen burning is not completely irreversible After a period of rest, In fact, part of it can be restored Of course, only with the naked eye and camera It can't accurately quantify the burning degree So we invited out the color calibrator again In fact, before the screen burning started, We have already carried out color correction and measurement on four solid color block areas of No.1 machine At that time, its color standard was like this After 30 days of high-intensity screen burning, Will there be some changes in their colors? According to the measured data, The color standard has indeed declined But the degree is not large The maximum E has only increased by less than 0.5 Belonging to a level that is basically imperceptible to the naked eye At the same time, the maximum brightness of the screen is slightly attenuated The maximum brightness of several color blocks decreased by 10 ~ 20nit It seems that aging still has some effects In general After a high strength test of 7 × 24 hours × 30 days, Both OLED laptops have a certain degree of screen burning phenomenon But after a day's rest, Their situation has improved again Whether observed by naked eyes, Or according to the data of the color calibrator This degree of screen burning does not affect daily use So it seems that this video can draw a successful conclusion? Obviously not I don't think just 30 days of testing is long enough Moreover, the burning degree of these two computers is upside down There is no reasonable explanation So I bought three more of the same computers Plus an IPS screen game book Repeated this test Simultaneously The two computers in front also followed It burned for another 30 days 60 days of data were obtained The experiment went on here It's really costly I hope everyone can see this and give it to a three-company Thanks a lot Another month has passed Let's first look at three machines used to do repeated tests These three computers burn screens to the same extent The icons in the upper left corner are slightly imprinted You can vaguely see solid color blocks on the right side If you look closely, Flight 3 is a little more serious This is also an unusual result Because the test conditions of Unit 3 and Unit 4 are exactly the same The No.5 machine corresponds to a more extreme scene Combined with the results of screen burning for 30 days in the previous units 1 and 2, We can come to the conclusion that First There are obvious individual differences in the burning speed of OLED screen Second Original factory system optimization And reducing the brightness from 400nit to 300 The effect on relieving screen burning is limited Can't even offset individual differences Of course, after a day's rest, All three computers have recovered On the whole, They all belong to the level that does not affect the use That is to say Even individuals with poor physique like No.3 machine It is also possible to withstand the stress test at the level of 30 days Don't worry too much As for the IPS screen notebook as a reference, Its situation is more in line with cognition Because of the display principle of LCD, It is not easy to burn the screen After 30 days of high intensity display, You can only see a shallow trace on the taskbar And after standing still for a day, It disappears completely Visible compared with OLED The durability of LCD screen will really be longer If special attention is paid to service life, LCD is still the first choice Finally, let's look at the highlights The performance of two "old comrades" who have been exercising for 60 days The taskbar burning screen of No.1 machine is already very obvious Belong to the level that can be seen at a glance The solid color block on the right side also has a visible burning screen Similarly, the icon mark on the left side becomes clearer and more distinguishable And even under normal use It is also easy to find Then there is Unit 2 Its taskbar burning screen is still relatively shallow It seems that dark mode can really slow down the aging of the taskbar area Its left icon mark is at about the same level as that of No.1 machine The solid color block on the right side is still darker than the No.1 machine Especially in green areas It is obvious that the color has darkened At the same time, the left video playback window also appeared traces It can be said that the burning screen is obvious But as we said earlier, The burning screen of OLED will recover after standing for a period of time After a day's cold machine trimming, The state of Unit 1 is much healthier again The icon on the left and the solid color block on the right are faded Only the afterimage of the bottom taskbar is obvious Machine 2 is taskbar health However, traces on solid color blocks and icons are still visible Personally, I think it belongs to the kind that needs to be carefully looked To the extent that it can be discovered Having said subjective performance Let's look at the data of the color calibrator First of all, the most obvious is brightness attenuation The brightness of the four blocks of Unit 1 has dropped by nearly 50nit Sensitive people should be able to detect it Color standard After 60 days The average E of all four color blocks exceeds 1 The maximum E is over 2.5 Although it is still at a good level, But the trend of deterioration is obvious For users who value color standards, You may need to re-calibrate the color Seeing here, everyone thinks Can these two computers burn screens for 60 days still work? Personally, I think Although both computers burned out some irrecoverable traces, But on the whole The influence on perception is still relatively small There is nothing wrong with daily use Of course, it's only me who says no This time, I'm going to use a third-party testing organization I sold the No.1 machine with the most serious burning screen in the taskbar to my trumpet on the idle fish At the same time, the "Inspection Treasure" service of idle fish is checked Theoretically speaking Inspection treasure will carry out professional testing on computers There are 13 items in the screen alone Common problems like burning screens Should be able to check out... Right? And guess what? The inspection report display screen is all right There is no aging at all Instead, an inconspicuous little bump on the C plane was detected Although this is only a machine test, Can not reflect the general situation But at least it shows that A computer that burns the screen continuously for 60 days in extreme scenes You can't see it at a glance From burning marks to completely unusable There should be a long way to go Well, after watching so many tests, I believe everyone's eyes are tired Synthesize all the data of this test I have come to the following conclusions For your reference First OLED does burn screen in Windows environment But the burning speed is not fast In the test It only takes 30 days Two OLED computers will appear in the afterimage visible to the naked eye against a gray background But after a day's rest in the cold machine, Most of the marks will recover After 60 days of high-intensity screen burning, Only in this way can there be obvious traces that cannot be eliminated But as long as you don't stare at it The impact is still small Even the third-party testing agency of salted fish can't find it Second Although the traces of OLED burning screen do not look obvious, However, there will be a large attenuation in color and brightness It can be seen from the data of the color calibrator After 30 days of testing, The change of data is not big But after 60 days, The color standard and brightness have obviously decreased It can already be regarded as two screens Therefore, if you have high requirements for color accuracy, brightness and other indicators, That's for OLED screens Regular color correction may be necessary Third Screen burning speed of OLED There are obvious individual differences Whether it's the first two machines, Or the next three retest computers There are some unusual data Or under the same conditions One burns the screen faster than the other Or one with low brightness Instead, burning the screen is more obvious There are indications that Individual differences between screens It has a great influence on the burning speed of OLED screen This level can even offset the effects of reduced brightness and software optimization Finally, if you are already using a computer with OLED screen, And if you want to prolong the service life as much as possible, I can give a few suggestions in combination with this test First, under the Windows environment, The most high-risk area is the taskbar at the bottom So using a dark theme is a good choice In addition, we can also turn on "Auto Hide Taskbar" However, some people may not be used to this function It is recommended to set according to your own preferences Another place where the screen is easy to burn This is the static picture of wallpaper and desktop icons There is no particularly good method for this Only at regular intervals Let's say two or three months Just change the position of the icon Change wallpaper (dynamic wallpaper can also be used) In fact, for the life of OLED, You don't have to worry too much We burned for 60 days in this experiment There are some obvious traces Considering the usage habits of most people, It takes a few hours to close the cover or rest the screen The life of OLED may be increased exponentially I think for at least a year There is no need to worry about burning the screen at all (please consider LCD for longer-term use with limited test data) And If you pay attention to forums such as Post Bar, you can find that The burning screen of notebook seems to be a problem of "much thunder and little rain" It has been used for several years to burn the screen. It is very rare With the progress of technology in the past two years, The life of OLED should be longer So I think we should never demonize OLED For users who are not prepared to regard computers as "heirlooms", Buy when you should As long as it is allowed to play its due value in a reasonable life That's enough
