Kev nkag siab txog dab tsi tiag tiag ua rau tus nqi coj zaub vaj huam sib luag pab koj ntsuas cov nqe lus kom raug, txheeb xyuas qhov chaw ua lag luam zoo - tawm, thiab tsim ib qhov project pob nyiaj siv uas qhia txog tus nqi tag nrho. Phau ntawv qhia no npog cov ntsiab lus tseem ceeb yam tsis muaj qhov tseeb.
Yog vim li cas tus nqi sib txawv heev
Ob lub teeb ci vaj huam sib luag nqe nqe lus rau tib lub suab pixel suab thiab qhov loj tuaj yeem sib txawv, thiab cov laj thawj tsis tshua pom los ntawm sab nraud. Cov khoom zoo, kev tsim khoom precision, calibration qauv, warranty kev pab them nqi, thiab tom qab - muag kev txhawb nqa muaj peev xwm cuam tshuam rau qhov chaw muag khoom tus nqi av. Tus nqi qis dua ntawm cov vaj huam sib luag coj teeb pom kev zoo feem ntau qhia txog qhov txo qis hauv ib lossis ntau qhov ntawm cov qhov ntev no - kev nkag siab uas pab koj txheeb xyuas seb qhov kev lag luam tawm -tawm puas tau rau koj daim ntawv thov.
Qhov no tsis txhais hais tias qis dua - cov nqi vaj huam sib luag yeej ib txwm tsis zoo, lossis tus nqi siab dua lav kev ua haujlwm zoo dua. Nws txhais tau hais tias tsis tshua muaj nqe lus hais txog kev ua lag luam tsim nyog cov lus nug tshwj xeeb, tsis lees txais ntawm lub ntsej muag tus nqi.
Tus nqi tseem ceeb tsav tsheb
Pixel Pitch
Pixel pitch (qhov chaw - mus rau - nruab nrab ntawm qhov nrug ntawm pixels uas nyob ib sab, ntsuas hauv millimeters) yog tus thawj tsav tsheb ntawm coj screen zaub vaj huam sib luag nqi ib square meter. Cov pitches zoo dua yuav tsum muaj cov khoom siv LED ntau dua hauv ib cheeb tsam, kev tsim PCB ntau dua, thiab siab dua - tsav tsheb zoo ICs - txhua qhov uas ntxiv tus nqi. Txoj kev sib raug zoo tsis yog -linear: zoo heev pitches (P1.2 thiab hauv qab) nqa cov nqi tseem ceeb tshaj li nruab nrab -ntau pitches.
| Pixel Pitch Range | Tus nqi txheeb ze ib m² | Daim ntawv thov |
|---|---|---|
| P1.2 – P1.9 | Siab | Zoo- suab sab hauv tsev: chav tswj, tshaj tawm |
| P2 – P3 | Nruab nrab -siab | Sab hauv video phab ntsa, boardrooms |
| P4 – P6 | Nruab nrab | Cov chaw loj hauv tsev, semi- sab nraum zoov |
| P8 – P10 | qis | Kev ua si sab nraum zoov, chaw ntau pob |
| P10+ | qis | Sab nraum zoov billboards, tsev facades |
Cov no yog cov piv txwv sib piv - tus nqi tiag tiag hauv txhua pawg tseem sib txawv raws li cov hauv qab no.
LED Component Zoo
Cov qib thiab cov lus qhia tshwj xeeb ntawm cov pob LED siv nyob rau hauv ib lub vaj huam sib luag yog ib qho ntawm cov khoom sib txawv loj tshaj plaws - thiab ib qho ntawm qhov pom tsawg tshaj plaws ntawm daim ntawv spec ib leeg.
