The answer in front had said the dominant position of OLED, I am told from another angle when OLED has visible defect, why to meet still sell like hot cakes.
Say to burn screen first, this is mixed very easily together screen quality problem is obscure. Say from technical angle, because red green La Zi is different like element glow time,OLED burns screen is, attenuation speed is so abhorrent, bring about with for a long time hind occurrence picture colour is inhomogenous, even double image.
The key came, appear the premise that burns screen is use time longer, those mobile phones are firm in one's hand, OLED screen appears colour is inhomogenous, have perpendicular line even (following graphs) , this does not make burn screen, be screen gives quality issue, what also nevers mention it, look for manufacturer to change.
Since respecting is used long just can burn screen, so this " long " how long? Somebody did a test technically with IPhone X (never mention it the egg of family idle aches, IPhone X changes a screen to be about thousands of RMB, be equivalent to buying a new homebred mobile phone, if screen is burned outside protect, that was sent greatly fortunately, so the test checks or very be necessary, lest flower treats unjustly money ah) .
The result shows, shine continuously screen carries a picture changeless more than 510 hours, IPhone X can appear the phenomenon that burn screen. Average person use mobile phone won't shine of idle continuously screen still carries a picture 510 hours changeless, this data is equivalent to 21 days not extinguish screen, although the lamp in the home is very few also,24 hours often shine, so from probability statistic angle for, burning screen is small probability incident, small to manufacturer be out of pocket won't let in the repair inside the expiration period.
Additional, the time that we change a mobile phone is 21 months commonly, be less than two years of time, before OLED screen begins ageing, the mobile phone has been thrown into the drawer to eat ash, burn the defect with screen and brief life to do not have the opportunity that erupt at all.
Because calculate,allow this just about, mobile phone manufacturer just can use OLED screen.
One reminds before the end, as a result of the characteristic of OLED screen, do not buy as far as possible those who use OLED screen is secondhand mobile phone, proceed with these mobile phones that have certain age, big probability can let you " in colour " .
