The energy efficiency standard for monitors, GB 21520-2023, will officially come into effect on June 1, 2024. This standard replaces GB 21520-2015, "Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Computer Monitors." Cov kev hloov pauv tseem ceeb thiab cuam tshuam yog raws li hauv qab no:
Dav dav ntawm Daim Ntawv Thov: Cov qauv no siv tau rau kev siv dav dav - lub hom phiaj thiab kev lag luam saib nrog lub vijtsam kab pheeb ces kaum loj tsis pub tsawg dua 40cm, siv los ntawm AC lossis DC, thiab siv cov kua siv lead ua kua (LCD) lossis cov teeb pom kev organic-emitting diode (OLED) cov lus qhia. Nws kuj tseem siv tau rau cov khoom siv sib xyaw ua ke uas siv los ntawm AC lossis DC, siv lub teeb -emitting diodes (LEDs) raws li cov qauv duab, nrog lub pixel suab siab dua 0.30mm thiab tsis siab tshaj 2.60mm, thiab qhov siab tshaj plaws tsis tshaj 3000 cd / m².
Cov Khoom Siv Tshwj Xeeb: Laptops, TVs, thiab ntau yam kev lag luam saib yog txhua yam raws li tus qauv no.
Hom Tsis Siv Tau: Cov kws tshaj lij- lub hom phiaj saib xyuas, dual- tshuaj ntsuam xyuas, thiab cov saib uas tsuas yog txhawb nqa roj teeb.
Yog vim li cas rau Kev Kho: Nrog kev nce qib hauv thev naus laus zis, kev ua lag luam sib faib ntawm kov- qhib cov khoom siv, siab- daws teeb meem, loj- cov khoom lag luam loj loj tau maj mam nce. OLED cov lus tau nkag mus rau hauv kev ua lag luam, thiab cov lus qhia LED tab tom txhim kho sai, tsim nyog rau kev lag luam tus qauv. Nyob rau tib lub sijhawm, cov tebchaws loj tsim tau tsim cov qauv kev siv hluav taws xob rau cov khoom siv. Txhawm rau txhim kho tag nrho cov khoom siv hluav taws xob ntawm kev ua lag luam, Tuam Tshoj suav nrog ntau hom kev qhia hauv nws cov qauv.
Kev kho ntau yam:
High-Kev Ua Tau Zoo Cov Lus Qhia Txog Kev Ua Haujlwm: Cov kev xav tau rau siab - cov lus qhia ua tau zoo tau raug kho thiab hloov kho, thiab cov kev xav tau rau siab -kev ua tau zoo OLED thiab LED cov khoom siv sib xyaw ua ke tau ntxiv.
Lub Xeev Cov Lus Txhais thiab Kev Xav Tau Lub Hwj Chim: Cov ntsiab lus ntawm "tawm lub xeev" thiab "lub xeev pw tsaug zog" tau hloov kho, thiab cov kev xav tau ntawm lub zog rau LCD thiab OLED cov lus tau raug kho dua. Piv txwv li, lub zog noj ntawm LCD thiab OLED cov lus qhia hauv lub xeev pw tsaug zog yuav tsum tsawg dua lossis sib npaug li 0.50W, thiab lub zog noj ntawm siab -kev ua tau zoo LCD thiab OLED cov lus qhia hauv lub xeev pw tsaug zog yuav tsum tsawg dua lossis sib npaug li 0.80W. Rau LCD thiab OLED cov lus qhia nrog lub xeev tawm, kev siv hluav taws xob hauv lub xeev tawm yuav tsum tsawg dua lossis sib npaug rau 0.40W, thiab rau siab -kev ua tau zoo LCD thiab OLED cov lus pom nrog lub xeev tawm, lub zog siv hauv lub xeev tawm yuav tsum tsawg dua lossis sib npaug rau 0.60W.
Kev Ntsuas Kev Hloov Kho: Qhov ntsuas qhov deb tau hloov pauv los ntawm "1m ntawm lub ntsuas hluav taws xob thiab lub ntsuas hluav taws xob" mus rau "3 npaug ntawm qhov screen qhov siab ntawm lub ntsuas hluav taws xob thiab lub ntsuas ntsuas." Cov kev cai hais txog DC fais fab mov tau ntxiv. Cov qauv kev sim thiab kev siv hluav taws xob zoo-txoj kev sim ntsuas rau OLED saib thiab LED tag nrho- hauv- ib lub PC tau ntxiv, thiab cov qauv ntsuas rau kab rov tav saib lub kaum sab xis, qhov kev daws teeb meem, xim gamut, thiab qhov sib piv ntawm siab -kev ua tau zoo LCDs, OLED saib, thiab kev ua haujlwm siab {1} {1} {8} PCs tau muab.
Lub Zog Efficiency Index Hloov Kho: Lub zog txuag hluav taws xob rau ntau hom kev saib xyuas tau raug hloov kho thiab tsim.
Siab zog Efficiency Requirements
Energy Efficiency Index Tsim: Cov khoom lag luam raug cais raws li cov txheej txheem tso saib thiab seb lawv puas siab - kev soj ntsuam kev ua tau zoo, thiab cov kev xav tau ntawm kev siv hluav taws xob hluav taws xob tau teev tseg nyias rau txhua pawg. Rau LCD saib, ib qho kev siv hluav taws xob sib cais tus nqi txwv tau teem rau 8K LCD saib.
Qhov taw qhia sib piv: Lub zog ua haujlwm qib 2 qhov ntsuas ntawm lub ntsuas hluav taws xob ntsuas tus qauv yog 10% siab dua qib 1 qhov ntsuas ntawm GB 21520-2015. Rau kev ua haujlwm siab LCD saib, lub zog ua haujlwm qib 2 qhov ntsuas ntawm lub zog saib xyuas tus qauv yog 26% siab dua qib 1 qhov ntsuas ntawm GB 21520-2015.
Kev cuam tshuam rau kev lag luam
Nyob rau hauv qab ntawm "dual carbon" cov hom phiaj thiab siab - cov khoom tsim tau zoo, kev tsim thiab kev siv cov qauv kev siv hluav taws xob rau cov neeg saib xyuas ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev txhim kho kev siv hluav taws xob hauv kev saib xyuas cov khoom thiab tswj xyuas cov khoom lag luam. Lawv kuj tseem ua lub hauv paus rau kev siv lub zog txuag hluav taws xob thiab lub zog -txuag cov ntawv pov thawj cov khoom.
