Muaj ntau lub tswv yim rau kev txhim kho LED zaub hauv tsev, thiab cov txheej txheem kev teeb tsa ntawm ntau lub tuam txhab LED zaub kuj txawv. Cov hauv qab no qhia txog 4 qhov sib txawv thiab ntau hauv tsev LED zaub tsim qauv. Tom qab ntawd sau nws qhov zoo thiab qhov tsis zoo ib qho los ntawm ib qho. Kuv vam tias nws yuav pab tau koj.
Sab hauv LED zaub tsim qauv
1. Dot matrix unit daws
Thawj qhov kev npaj tsim tau tsim los ntawm sab hauv tsev pseudo-xim dot matrix npo.
Qhov zoo: Tus nqi kom zoo dua ntawm cov khoom siv raw yog qhov loj tshaj plaws, kev tsim khoom thiab kev siv tshuab yog yooj yim, thiab qhov zoo yog ruaj khov.
Disadvantages: tsis zoo xim sib xws, loj jigsaw phenomenon, tsis pom zoo nyhuv.
2. Ib txoj kev teeb pom kev zoo
Txhawm rau daws qhov teeb meem xim ntawm lub vijtsam dot matrix, tsab xov xwm no rub tawm cov tswv yim ntawm cov khoom siv sab nraum zoov, thiab hloov cov pixel multiplexing sab nraum zoov (tseem hu ua pixel sib koom, virtual pixel) thev naus laus zis rau lub vijtsam sab hauv tsev tib lub sijhawm.
Qhov zoo: Xim sib xws yog zoo dua li dot matrix hom.
Qhov tsis zoo: Cov xim sib xyaw xim tsis zoo, qhov pom lub kaum ntse ntse tsis loj, thiab cov xim tsis zoo thaum saib kab rov tav. Cov txheej txheem kho mob yog qhov nyuaj, thiab cov kev cai antistatic siab heev.
3. Sub-nto mounting tov
Qhov tseeb, qhov no yog kev txhim kho ntawm ib qho kev daws teeb meem, thiab nws tseem tab tom txhim kho.
Qhov zoo: cov duab xim sib xws, saib lub kaum ntse ntse thiab lwm qhov ntsuas thawj zaug tsis txawv ntau los ntawm kev daws teeb meem ib leeg, tab sis tus nqi qis dua, cov duab pom tau zoo, thiab kev daws teeb meem theoretical tuaj yeem ncav cuag ntau dua 17,200.
Qhov tsis zoo: Kev ua haujlwm yog qhov nyuaj dua, thiab cov kev cai antistatic siab heev.
4. Patch txoj kev npaj
Qhov kev daws teeb meem no yog siv lub patch-type luminous raj raws li cov khoom siv.
Qhov zoo: Cov xim sib xws, lub kaum ntse ntse thiab lwm yam tseem ceeb qhia tau yog qhov zoo tshaj plaws hauv cov kev daws teeb meem uas twb muaj lawm, tshwj xeeb tshaj yog cov xim sib xyaw ntawm peb-hauv-ib qhov chaw mount yog zoo heev.
Disadvantages: teeb meem kev ua thiab tus nqi siab.
