Puas yog OLED zoo dua rau koj lub qhov muag?

Raws li lub sijhawm tshuaj ntsuam txuas ntxiv nce thoob ntiaj teb, kev txhawj xeeb txog qhov cuam tshuam ntawm cov thev naus laus zis ntawm qhov muag kev noj qab haus huv tau nce siab. Ntawm cov kev sib cav, ib lo lus nug sawv tawm: Puas yog OLED (Organic Light-Emitting Diode) thev naus laus zis zoo dua rau koj ob lub qhov muag piv rau cov ntxaij vab tshaus LCD? Cia's dhia rau hauv kev tshawb fawb, cov txiaj ntsig, thiab cov lus ceeb toom ntawm OLED cov lus.

OLED cov ntxaij vab tshaus muaj npe nrov rau lawv cov xim zoo nkauj, cov xim dub sib sib zog nqus, thiab siv zog ua haujlwm. Tsis zoo li LCDs, uas tso siab rau lub teeb pom kev zoo, txhua pixel hauv OLED vaj huam sib luag emits nws lub teeb. Qhov kev tsim tshwj xeeb no muaj ob qho txiaj ntsig zoo rau qhov muag kev nplij siab:

Lower Blue Light Emission

Cov kev tshawb fawb qhia tias ntev raug rau ** xiav lub teeb **—tshwj xeeb hauv 400-450nm wavelength ntau yam—tuaj yeem cuam tshuam kev pw tsaug zog thiab pab txhawb rau qhov muag digital. OLED cov ntxaij vab tshaus tawm lub teeb xiav tsawg dua li cov LCDs ib txwm muaj, tshwj xeeb tshaj yog thaum pom cov ntsiab lus tsaus. Raws li daim ntawv tshaj tawm xyoo 2021 los ntawm *Harvard Health Publishing*, OLED's muaj peev xwm mus dim ib tug pixels (es tsis txhob siv ib tug uniform backlight) txo tag nrho cov xiav lub teeb tso zis ntau txog 30% nyob rau hauv tsaus hom.

Flicker-Free Performance

Ntau cov ntxaij vab tshaus LCD siv PWM (Pulse Width Modulation) los kho qhov ci ntsa iab, uas ua rau lub teeb rov qab sai sai rau thiab tawm. Qhov flickering no, feem ntau imperceptible, tau txuas rau mob taub hau thiab qhov muag qaug zog hauv cov tib neeg rhiab heev. OLED cov ntxaij vab tshaus, txawm li cas los xij, tswj qhov ci los ntawm kev kho pixel luminance ncaj qha, tshem tawm flicker feem ntau.

Thaum OLEDs tuav cov lus cog tseg, lawv qhov cuam tshuam rau qhov muag kev noj qab haus huv nyob ntawm cov qauv siv thiab kev siv thev naus laus zis:

PWM hauv Ib txhia OLEDs Ironically, tej yam OLED cov lus (xws li, nyiaj txiag smartphones) tseem siv PWM rau qis-brightness chaw txuag lub hwj chim. Qhov no tuaj yeem rov qhia cov teeb meem flickering.

Brightness Extreme:OLED cov ntxaij vab tshaus teem rau qhov siab tshaj plaws nyob rau hauv qhov chaw tsaus ntuj yuav ua rau pom kev, tawm tsam lawv cov txiaj ntsig xiav-lub teeb.

Burn-In Risks:Cov ntsiab lus zoo li qub (piv txwv li, navigation bars) ntawm OLEDs tuaj yeem degrade pixels lub sijhawm, ua rau cov neeg siv kom ci ntsa iab.—tej zaum yuav ua rau qhov muag tsis zoo.

Cov kws tshaj lij pom

Dr. Lisa Carter, kws kho qhov muag ntawm lub Vision Health Institute, piav qhia:

“OLEDs yog ib kauj ruam rau pem hauv ntej rau qhov muag kev nplij siab, tshwj xeeb tshaj yog nrog lawv txo qis lub teeb xiav thiab tsis muaj flicker. Txawm li cas los xij, cov neeg siv yuav tsum tseem ua raws li txoj cai 20-20-20: txhua 20 feeb, saib ib yam dab tsi 20 taw deb li 20 vib nas this. Tsis muaj kev tshuaj ntsuam tshuab tuaj yeem hloov cov cwj pwm noj qab haus huv.”

Lub caij no, cov kws tshuaj ntsuam thev naus laus zis qhia txog kev nce qib hauv OLED hom kev saib xyuas qhov muag:Samsung's “Eye Comfort Shield”dynamically kho lub teeb xiav raws li lub sijhawm ntawm hnub.LG's “Kev nplij siab saib”muab lub teeb xiav qis nrog cov tshuaj tiv thaiv glare.

OLED cov ntxaij vab tshaus, nrog rau lawv qhov zoo sib xws thiab txo lub teeb xiav, muab qhov zoo dua rau qhov muag pom kev zoo dua li LCDs.—yog tias lawv siv lub luag haujlwm. Txawm li cas los xij, yam xws li teeb ci ci, kev ua haujlwm tsis muaj flicker, thiab tus cwj pwm ergonomic tseem ceeb heev.
