Nyob Sab Hauv Tsev Hloov Teeb Meem LED P10.4 Pixel Pitch Nrog 3840 HZ Rov Ua Dua

Cov Lus Qhia Tseem Ceeb ntawm Led zaub

1. Dab tsi yog LED?

LED yog sanded rau Lub Teeb Emitting Diode, ib hom semiconductor uas siv los muab thiab txais cov hluav taws xob teeb liab rau hauv duab hluav taws xob sab hauv lossis duab ci ci, siv cov yam ntxwv ntawm cov khoom sib xyaw. Qhov no yog siv rau cov khoom siv hauv tsev, cov chaw taws teeb tswj, hluav taws xob xov hluav taws xob, ntau yam khoom siv thev naus laus zis.

2. Dab Tsi yog Cov Nqaij Npav, Pixel Density, LED QTY, thiab Pixel Kho Kom Zoo Nkauj yog dab tsi?

Pixel Pitch yog qhov kev ncua deb ntawm cov neeg nyob ze pixels.

Pixels ceev yog qhov ntau ntawm pixels ib square meter.

LED QTY yog qhov ntau ntawm LED teeb ib square.

Xws li lub Pixel Kev Kho Mob yog qhov kev piav qhia ntawm lub teeb meem ntawm lub pixel, piv txwv li, peb siv 1 lub teeb liab, 1 lub teeb ntsuab, thiab 1 lub teeb xiav los sau lub pixel, cov teeb tsa pixel yog 1R1G1B.

3. Dab tsi yog LED Hom, Module qhov loj me thiab Module daws teeb meem?

LED Hom yog qhov kev piav qhia ntawm LED teeb, piv txwv li, hom, hom duab nyob hauv lub cev, qhov loj me ntawm lub teeb, thiab lwm yam.

Module me me yog ntsuas ntawm lub module.

Module daws teeb meem yog tus naj npawb ntawm pixels ib module.

4. Dab tsi yog Tsav Txoj Kev, tsav tsheb IC thiab Fais fab mov

Tsav Txoj Kev: ib txwm peb siv zoo li qub, 1/4 scan, 1/8 scan, 1/16 scan, qhov tom kawg ua rau tsis tshua pom kev tsawg dua li qub. Peb ib txwm siv qhov zoo nkauj sab nraum zoov, thiab siv ntau hom scan hauv sab hauv.

Tsav tsav tsheb IC yog cov ntsiab lus siv dav dav rau ntau hom IC, uas tau siv los tswj cov teeb txawb LED, thiab ua tus choj ntawm kev tswj hwm thiab lub teeb txawb.

Kev siv fais fab: ib hom khoom siv uas siv los hloov los ntawm 220V AC mus rau 5V DC. Nws ib txwm pom zoo li lub thawv nyob hauv lub txee.

5. Dab tsi yog saib lub kaum ntse ntse?

Saib lub kaum sab xis yog lub kaum sab xis siab kawg uas qhov ntsuas pom tau tuaj yeem pom nrog qhov ntsuas pom tau zoo. Nws suav nrog kab rov tav pom lub kaum ntse ntse thiab lub kaum sab xis ntsug.
