Thaum xaiv lub vijtsam LED sab hauv tsev, cov ntsiab lus tseem ceeb hauv qab no yuav tsum tau xav txog:
1. Real Pixels vs. Virtual Pixels
Tiag tiag Pixels: Txhua pixel muaj peb qhov tseeb LEDs (liab, ntsuab, thiab xiav), uas ua rau muaj qhov tshwm sim muaj tseeb dua.
Virtual Pixels: Los ntawm kev txhais tau tias, tus naj npawb ntawm pixels tau nce los ntawm kev sib koom pixels nyob ib sab, yog li ua tiav qhov pom kev zoo dua. Virtual pixels tuaj yeem txo cov nqi rau qee qhov, tab sis cov nyhuv tso saib yuav ua rau me ntsis qis dua rau cov pixels tiag.
2. Chip Quality
Qhov tseem ceeb: LED nti yog qhov tseem ceeb ntawm lub vijtsam LED, cuam tshuam ncaj qha rau qhov ci, xim, thiab lub neej ntev ntawm cov zaub.
Cov Kev Cai Xaiv: Xaiv cov chips los ntawm qhov zoo-cov npe paub nrog kev ntseeg tau zoo kom ntseeg tau tias muaj kev ruaj ntseg thiab ua haujlwm ntev ntawm LED zaub screen.
3. Daim ntawv ntim khoom
Tib Lub Teeb: Lub kaum sab xis me me, qhov ci ci dua, tus nqi qis dua, tab sis tsis zoo sib xws.
Sub-Nto Mount: Ib qho kev txhim kho ntawm ib lub teeb, tab sis tseem yog cov khoom hloov pauv.
Nto Mount (SMT) Pob (3-in-1 SMT thiab 3-in-1 SMT): Lub kaum sab xis pom dav, lub teeb pom kev zoo sib xws, yooj yim rau automate soldering, thiab yog cov khoom lag luam tseem ceeb rau cov ntxaij vab tshaus LED, tab sis tus nqi kuj siab.
Kev pom zoo xaiv: Xaiv hom pob tsim nyog raws li koj cov peev nyiaj thiab kev siv qhov xwm txheej. Rau siab - daim ntawv thov kev thov, SMT ntim tau pom zoo.
4. Dot Ceev
Lus Txhais: Dot ntom yog hais txog tus naj npawb ntawm LED pixels ib cheeb tsam, cuam tshuam ncaj qha rau kev daws teeb meem thiab qhov pom tseeb ntawm lub vijtsam.
Kev txiav txim siab: Vim yog qhov tsim hluav taws xob siab ntawm sab hauv tsev puv - xim LED chips thiab lub siab ceev ntawm kev tswj Circuit Court, qhov ntom ntom tsis tuaj yeem siab dhau. Qhov sib npaug yuav tsum raug ntaus ntawm qhov pom qhov deb thiab pom cov nyhuv thaum xaiv.
5. Txoj kev tsav tsheb
Kev tsav tsheb tsis tu ncua: Sab hauv tsev puv - xim LED zaub feem ntau siv kev tsav tsheb tam sim no los xyuas kom ruaj khov LED teeb emission.
Scanning Method: Feem ntau suav nrog 1/4 scan, 1/8 scan, thiab lwm yam. Nrog rau tib lub nti, ib qho kev ua kom zoo dua scanning ua rau ntau circuitry thiab brightness ntau dua.
Kev Pom Zoo Kev Xaiv: Xaiv txoj kev ntsuas qhov tsim nyog raws li koj qhov kev siv scenario thiab pob nyiaj siv. Rau siab - daim ntawv thov yuav tsum tau, 1/4 scan los yog ntau dua precision scanning txoj kev yog pom zoo.
6. Zaub Performance
Brightness thiab Contrast: xyuas kom meej tias cov zaub tuaj yeem pom cov ntsiab lus hauv cov teeb pom kev zoo sab hauv.
Xim Accuracy: Xaiv cov zaub nrog cov xim raug siab kom ntseeg tau tias qhov tseeb ntawm cov ntsiab lus pom.
Saib lub kaum sab xis: Xyuas kom cov zaub tswj qhov pom kev zoo los ntawm ntau lub kaum ntse ntse.
7. Tom qab-Kev Pabcuam Muag
Hom Lub Npe: Xaiv lub npe zoo -paub hom kom paub meej cov khoom zoo thiab tom qab- kev muag khoom.
Kev Pabcuam Kev Pabcuam: Nkag siab seb tus neeg muag khoom puas muab kev txhawb nqa thiab tom qab- kev muag khoom kom cov teeb meem tuaj yeem daws tau sai thaum siv.
8. Kev txhim kho thiab tu
Txoj Kev Txhim Kho: Xaiv txoj kev teeb tsa tsim nyog raws li kev siv cov xwm txheej, xws li phab ntsa -mounted lossis recessed.
Maintenance Ease: Xav txog qhov yooj yim ntawm kev saib xyuas ntawm cov zaub, xws li seb nws puas yooj yim rau disassemble thiab huv.
Hauv cov ntsiab lus, thaum xaiv cov khoom siv sab hauv LED, nws yog ib qho tsim nyog yuav tsum ua tib zoo xav txog ntau yam, suav nrog cov pixels tiag tiag thiab virtual, nti zoo, daim ntawv ntim, dot ceev, txoj kev tsav tsheb, cov nyhuv tso tawm, tom qab - kev muag khoom, thiab kev teeb tsa thiab kev saib xyuas. Los ntawm kev ntsuam xyuas cov yam ntxwv no, koj tuaj yeem xyuas kom meej tias koj xaiv lub siab - LED zaub zoo uas ua tau raws li koj xav tau.
