Lub suab qws qaim qhia qhov pixel ntom ntom ntog hauv lub vijtsam LED, uas cuam tshuam txog cov duab daws teeb meem. Nws hais txog PX (PHXmm), raws li qhov kev ncua deb (hauv millimetres) nruab nrab ntawm ob lub pixels los ntawm qhov nruab nrab ntawm ib lub pixel txog rau nruab nrab ntawm ib lub pixel uas nyob ib sab. X mm yog qhov kev ncua deb ntawm ob lub LED hauv LED npo. Piv txwv li, P4 (Ph4) yog qhov deb ntawm 4 hli ntawm ob lub LEDs (kab rov tav thiab ntsug).
1.Video Kev Daws Teeb Meem
Feem ntau cov nqaim nqaim dav dav yuav muaj qhov chaw tsis tshua muaj pes tsawg ntawm pixels, uas ua rau lub suab pixel sib txawv nrog qhov sib txawv video daws teeb meem raws tib qhov loj me.
P6.67 320mmx160mm 48dotsx24dots
P10320mmx160mm 32dotsx16dots
Yog li no, nqaim zog pixel pitch txhim kho qhov kev daws teeb meem vim nws muaj ntau LEDs (ntau pixels). Ntau tus pixels ua tiav cov ciam teb ciam teb thiab cov ncauj lus kom ntxaws ntxaws thiab coj cov khoom pom zoo tshaj plaws pom kev. Qhov nqaim pixel ntxig ntxiv kuj tso cai rau tus saib kom ze rau qhov ze ntawm lub vijtsam thiab txaus siab rau cov duab pom meej uas tsis muaj qhov cuam tshuam ntawm pom tus neeg ib tus pixels.
Txawm li cas los xij, nws tsis yog qhov kev xaiv zoo tshaj plaws rau txhua qhov xwm txheej los ntawm xaiv txoj kev nqaim pixel me me.
2.Ntsuas Qhov Loj
Yog tias qhov kev daws teeb meem ib yam, qhov nqaim ntawm lub suab me me muaj qhov me dua.
Forexample, 1080P (1920x1080 pixels) daws teeb meem. P1.5LED npo, lub dimension yuav 2.44x1.372m; P3.91, LED npo, lub dimension yuav 7.5mx4m.
Yog tias yuav tsum muaj tib lub vijtsam dim, lub pixel me me tau muaj kev daws teeb meem ntau dua (ntau dua pixels).
Piv txwv, 3x2m npo. P2.604 LED npo, qhov kev daws teeb meem yuav yog 1152x768pixels; P4.81 LED npo, qhov kev daws teeb meem yuav yog 624x416pixels.
Cov num sib txawv yuav tsum muaj ntsuas txawv raws li qhov xav tau ntawm qhov project. Txawm hais tias nqaim pixel pitch coj cov kev daws teeb meem ntau dua, lub me me pixel pitch tsis tuaj yeem ntsib qee qhov kev thov tiag tiag thiab xws li kev ua yeeb yam loj.
Dhau li ntawm qhov ntev ntawm lub vijtsam, saib qhov deb kuj tseem yog qhov tseem ceeb.
3.Saib Kev Deb
Cov vijtsam LED yog lub TV tsis zoo uas peb tuaj yeem saib hauv qhov ze txawm tias qis dua 1 meter (3.28ft). Rau ib qho screen LED, nws muaj qhov pom tsawg kawg.
Saib lub vijtsam LED ntawm qhov nrug deb, tus saib yuav txaus siab rau cov duab lossis yeeb yaj kiab tiag tiag. Txwv tsis pub, cov duab thiab cov yeeb yaj kiab zoo yuav tsis zoo uas tus saib yuav yooj yim cuam tshuam los ntawm qhov tsis pom tus neeg lub pixels.
Pixel Suab | Yam tsawg kawg nkaus nrug deb |
1.2 hli | 1.2m(3.94t) |
1.5 hli | 1.5m (4.92ft) |
1.7 hli | 1.7m (5.58ft) |
2.0 hli | 2m (6.56ft) |
2.5 hli | 2.5m (8.2ft) |
3 hli | 3m (9.84ft) |
4 hli | 4m (13.12ft) |
5hli | 5m (16.4ft) |
6 hli | 6m (19.68ft) |
8 hli | 8m (26.24ft) |
10 hli | 10m (32.8ft) |
Txheeb xyuas qhov kev ncua deb ntawm kev tshuaj ntsuam mus rau qhov ze ze rau LED qhov project qhov project, tom qab ntawd xaiv ib qho uas me dua qhov deb. Tus me, zoo dua.
Ntawm couse, qhov kev txiav txim siab dua txhais tau tias cov nqi ntau dua.
4.Txoj Haujlwm Nyiaj Siv
Yog li nws yuav zoo dua los xaiv cov pixel pitch tsim nyog raws li cov phiaj xwm peev nyiaj. Lub sijhawm no, koj yuav tsum tau txiav txim siab txog tus qauv ua lub tsev, tus nqi nruab thiab lwm yam nqi tshwj tsis yog tus nqi coj screen.
Zoo siab txais tos hu rau peb nrog koj qhov kev coj screen project!
