Cov ntsiab lus xws li "zog-txuag kev ntsuam xyuas tus nqi," "siab- cov khoom ua tau zoo," thiab "tus qauv zaub" raug tshem tawm.
Cov kev hloov pauv hauv kev xeem yuav tsum tau ua
Lub zog ua kom muaj zog rau ntau theem ntawm LCD cov lus tau raug kho dua tshiab, thiab cov kev xav tau ntawm kev siv hluav taws xob rau ntau qib ntawm OLED cov lus qhia thiab LED cov khoom siv sib xyaw ua ke tau ntxiv.
Cov kev txiav txim siab rau siab -kev ua tau zoo LCD zaub, siab -kev ua tau zoo OLED zaub, thiab siab -kev ua tau zoo LED kev sib xyaw ua ke tau ntxiv.
Kev txwv fais fab rau lub xeev pw tsaug zog tau raug kho dua, thiab kev siv hluav taws xob tsis zoo rau OLED cov lus qhia thiab LED cov khoom siv sib xyaw ua ke tau ntxiv.
Kev Txhim Kho Kev Xeem
Cov kev cai rau lub hwj chim mov voltage thiab tag nrho cov harmonic distortion (THD) raug nyob rau hauv AC zog tej yam kev mob tau nce, thiab lub hwj chim mov voltage yuav tsum tau nyob rau hauv DC hwj chim tej yam kev mob tau ntxiv.
Qhov raug thiab ntsuas ntau yam ntawm lub luminance meter thiab lub zog ntsuas hluav taws xob tau raug txhim kho, thiab cov kev xav tau rau cov khoom siv ntsuas hluav taws xob tsim tau ntxiv.
Cov kev xav tau rau qhov kev xeem sib txuas sib txuas ua ke, kuaj cov teeb liab yuav tsum tau, thiab DC fais fab mov ntsuas qhov system tau ntxiv.
Cov kev xav tau tshwj xeeb rau kev teeb tsa nrog cov roj teeb, ua -hauv cov neeg hais lus, lossis tsim- hauv cov khoos phis tawj tau qhia meej, thiab cov teeb liab ua ntej thiab ntsuas qhov nrug ntawm lub ntsuas hluav taws xob thiab cov zaub tau raug hloov kho.
Cov kev xeem uas yuav tsum tau muaj rau OLED cov lus qhia thiab kev sib xyaw ua ke ntawm LED zaub terminals tau ntxiv.
III. Scope of Application of the New Standard
GB 21520-2023 siv rau cov khoom hauv qab no:
Planetary thiab nkhaus dav dav -Lub hom phiaj thiab kev lag luam qhia nrog lub vijtsam kab pheeb ces kaum qhov loj tsis pub tsawg tshaj 40 cm, siv los ntawm AC lossis DC, thiab siv cov kua siv lead ua kua (LCD) lossis cov teeb pom kev organic-emitting diode (OLED) qhia;
