M'dziko lazowonetsera za LED, "khadi lotumiza" (lomwe limadziwikanso kuti khadi lotumizira kapena transmitter) limagwira ntchito yofunikira popereka zowoneka bwino kwambiri. Kachipangizo kakang'ono koma kamphamvu kameneka kamakhala ngati mlatho pakati pa zomwe zili mkati ndi chophimba cha LED, kuwonetsetsa kuti zithunzi, makanema, ndi zithunzi zanu zikuwonekera bwino komanso mosasinthasintha. Mu bukhuli, tiwona kuti khadi yotumiza ndi chiyani, momwe imagwirira ntchito, komanso chifukwa chake ili yofunikira kuti chiwonetsero cha LED chiwoneke bwino.
1. Kodi Send Card ndi Chiyani?
Khadi lotumiza ndi gawo lamagetsi paziwonetsero za LED zomwe zimatembenuza mavidiyo kapena zithunzi za data kuchokera ku chipangizo choyambira (monga kompyuta kapena media player) kukhala mawonekedwe omwe chiwonetsero cha LED chingathe kukonza. "Imatumiza" zomwe zili ku khadi yolandirirayo, yomwe imayang'anira ma module a LED, kuwonetsetsa kuti pixel iliyonse ikuwonetsa molondola komanso mosazengereza.
2. Ntchito Zofunika Kwambiri pa Send Card
Khadi lotumiza limagwira ntchito zingapo zofunika zomwe zimakhudza mwachindunji mtundu ndi kudalirika kwa zowonetsera za LED:
a. Kusintha kwa Data
Khadi lotumiza limatenga zomwe zili kunja, ndikuzisintha kukhala mawonekedwe oyenera kuti chiwonetsero cha LED chiwerengedwe ndikuwonetsa. Kusinthaku kumawonetsetsa kuti zomwe zili m'gululi zikuwonekera momwe akufunira, mitundu, ndi mtundu wake.
b. Kutumiza kwa Signal
Pambuyo potembenuza deta, khadi yotumizayo imatumiza ku khadi (ma) omwe amalandira kudzera pazingwe. Kutumiza kumeneku ndikofunikira kwambiri pazowonetsera za LED, makamaka pakuyika kwakukulu komwe makhadi olandila angapo amakhudzidwa pakugawa malo owonetsera.
c. Sonyezani kulunzanitsa
Kwa zowonera zopanda msoko, khadi yotumiza imagwirizanitsa zomwe zili m'magawo osiyanasiyana a chiwonetsero cha LED. Kuyanjanitsa uku kumathetsa zovuta monga kung'ambika kapena kusanja, makamaka pakukhazikitsa kwakukulu kwa LED komwe makhadi olandila angapo amayang'anira magawo osiyanasiyana a skrini.
d. Kuwala ndi Kusintha kwa Mitundu
Makhadi ambiri amalola ogwiritsa ntchito kusintha kuwala, kusiyanitsa, ndi mitundu. Kusinthasintha kumeneku ndikofunikira kuti musinthe mawonekedwe kuti agwirizane ndi malo osiyanasiyana, monga malo akunja kapena m'nyumba okhala ndi zowunikira zosiyanasiyana.
3. Mitundu ya Makhadi Otumiza
Kutengera kugwiritsa ntchito komanso kukula kwa chiwonetsero cha LED, mitundu ingapo yamakhadi otumizira ilipo:
a. Standard Send Cards
Makhadi otumizira okhazikika ndi abwino kwa zowonera zazing'ono mpaka zapakatikati za LED komanso ntchito zoyambira. Amapereka magwiridwe antchito ofunikira monga kutumiza deta ndi kulunzanitsa koma mwina sangagwirizane ndi masinthidwe apamwamba pakuyika kwakukulu.
b. Makhadi Apamwamba Othandizira
Kwa mawonedwe akuluakulu a LED kapena zowonetsera zapamwamba, makhadi otumizira apamwamba amapereka mphamvu zogwirira ntchito zapamwamba ndi chithandizo cha mitengo yapamwamba ya deta. Nthawi zambiri amagwiritsidwa ntchito m'malo omwe amafunikira matanthauzidwe apamwamba, monga kutsatsa kwakunja, zisudzo, ndi mabwalo amasewera.
c. Makhadi Opanda Ziwaya
Makhadi ena otumiza amabwera ndi njira zolumikizirana opanda zingwe, zomwe zimakhala zopindulitsa pakuyika komwe kulibe ma cabling. Amapereka kusinthasintha ndikulola ogwiritsa ntchito kuwongolera ndikusintha zomwe zili kutali.
4. Momwe Mungayikitsire Send Card mu Chiwonetsero cha LED
Kuyika kirediti kadi ndikosavuta koma kumafuna kusamalitsa kuti muwonetsetse kuti zikuyenda bwino. Nazi njira zoyambira:
Pezani kagawo kakadi yotumiza pa chowongolera kapena chosewerera media.
Lowetsani khadi yotumiza molimba m'malo osankhidwa. Onetsetsani kuti ndiyolumikizidwa bwino kuti mupewe kusokoneza masaini.
Lumikizani zowonetsera ku khadi yotumiza pogwiritsa ntchito zingwe zomwe zimagwirizana (nthawi zambiri Ethernet kapena HDMI).
Konzani makonda kudzera pa mapulogalamu operekedwa ndi wopanga khadi yotumiza. Sitepe iyi imawonetsetsa kuti zosintha zowonetsera, monga kuwala ndi kusanja, zisinthidwa malinga ndi zomwe mukufuna.
Yesani chiwonetserochi kuti muwonetsetse kuti mbali zonse za chophimba cha LED zikugwira ntchito bwino, popanda ma pixel akufa, kuchedwa, kapena kusagwirizana kwamitundu.
5. Nkhani Wamba ndi Tumizani Makhadi ndi Kuthetsa Mavuto
Ngakhale ndi odalirika, kutumiza makhadi nthawi zina kumatha kukumana ndi zovuta. Nazi zovuta zingapo zomwe zimachitika komanso njira zothetsera mavuto:
a. Palibe Chiwonetsero kapena Black Screen
Yang'anani kugwirizana pakati pa khadi lotumiza, kompyuta, ndi makadi olandira.
Onetsetsani kuti khadi yotumizayo yalowetsedwa bwino komanso kuti zingwe zonse zalumikizidwa bwino.
b. Zithunzi Zosakwanira Kapena Mitundu Yopotoka
Sinthani zowonetsera pa pulogalamu yamakhadi otumizira, kuyang'ana kwambiri kuwala, kusiyanitsa, ndi mitundu.
Yang'anani ngati firmware yotumiza khadi ili ndi nthawi, popeza opanga nthawi zina amatulutsa zosintha kuti athetse zovuta zomwe zimadziwika.
c. Kuchedwa kapena Kuchedwa kwa Signal
Tsimikizirani kuti khadi yotumizira ikugwirizana ndi kukula ndi mtundu wa chiwonetsero chanu cha LED.
Pa zowonetsera zazikulu, ganizirani kugwiritsa ntchito makadi otumiza ochita bwino kwambiri kuti mugwiritse ntchito deta yokwera bwino bwino.
6. Kusankha Khadi Lotumiza Loyenera la Chiwonetsero Chanu cha LED
Posankha khadi yotumizira, ganizirani zotsatirazi kuti muwonetsetse kuti ikugwirizana ndikugwira ntchito:
Kukula kwa Screen ndi Kukhazikika: Zowonetsa zowoneka bwino nthawi zambiri zimafunikira makadi otumiza ochita bwino kwambiri.
Malo Oyikirako: Zowonetsa panja zingafunike kutumiza makadi okhala ndi zowonjezera zoteteza nyengo kapena zoteteza.
Zofunikira Zowongolera: Ngati mukufuna kuwongolera zowonetsera kutali, yang'anani makhadi otumizira omwe ali ndi njira zolumikizira opanda zingwe.
Mtundu wa Zinthu: Pamavidiyo oyenda mwachangu kapena zinthu zotsogola, sungani ndalama zanu mumakhadi otumizira omwe amathandizira mitengo yokwera kwambiri kuti musewere bwino.
7. Malingaliro Omaliza
Mu makina owonetsera a LED, khadi yotumiza ndiye ngwazi yosadziwika yomwe imatsimikizira kuti zomwe muli nazo zimaperekedwa monga momwe mukufunira. Potembenuza ndi kutumiza deta moyenera, imasunga kukhulupirika kwa zowoneka pazithunzi zonse, kupititsa patsogolo kuwonera kwa omvera. Kaya muyike kachiwonetsero kakang'ono m'nyumba kapena khoma lalikulu lakunja la LED, kusankha ndi kukonza khadi yotumizira yoyenera ndikofunikira kuti mugwire bwino ntchito.
