Emhlabeni wezibonisi ze-LED, "ikhadi lokuthumela" (elibuye laziwe njengekhadi lokuthumela noma ikhadi lokudlulisela) lidlala indima ebalulekile ekuletheni okubonakalayo kwekhwalithi ephezulu. Le divayisi encane kodwa enamandla isebenza njengebhuloho phakathi komthombo wokuqukethwe nesikrini se-LED, iqinisekisa ukuthi izithombe zakho, amavidiyo, nezithombe ziboniswa ngokucacile nangokungaguquguquki. Kulo mhlahlandlela, sizohlola ukuthi liyini ikhadi lokuthumela, lisebenza kanjani, nokuthi kungani libalulekile ekusebenzeni okuhle kwesibonisi se-LED.
1. Liyini i-Send Card?
Ikhadi lokuthumela liyingxenye ye-elekthronikhi ekubonisweni kwe-LED eguqula idatha yevidiyo noma yesithombe isuka kudivayisi engumthombo (njengekhompyutha noma isidlali semidiya) ibe yifomethi isibonisi se-LED esingase siyicubungule. Empeleni "ithumela" idatha yokuqukethwe ekhadini elamukelayo, elibe selihlela idatha yamamojula e-LED ngamanye, liqinisekisa ukuthi iphikseli ngalinye liboniswa ngokunembile futhi ngaphandle kokulibala.
2. Imisebenzi Esemqoka Yekhadi Lokuthumela
Ikhadi lokuthumela liphethe imisebenzi embalwa ebalulekile ethinta ngokuqondile ikhwalithi nokuthembeka kwezibonisi ze-LED:
a. Ukuguqulwa Kwedatha
Ikhadi lokuthumela lithatha okuqukethwe emithonjeni yangaphandle, likuguqule libe yifomethi efanele ukuze isibonisi se-LED sifundwe futhi siboniswe. Le nqubo yokuguqulwa iqinisekisa ukuthi okuqukethwe kuvela ekulungisweni okuhlosiwe, imibala, kanye nekhwalithi.
b. Ukudluliselwa Kwesiginali
Ngemva kokuguqula idatha, ikhadi lokuthumela liyidlulisela ekhadini elitholayo ngamakhebuli. Lokhu kudlulisela kubalulekile ekubonisweni kwe-LED, ikakhulukazi ekufakweni okukhulu lapho amakhadi okwamukela amaningi ebandakanyeka ekuhlukaniseni indawo yokubonisa.
c. Bonisa Ukuvumelanisa
Ngokubukwa okungenamthungo, ikhadi lokuthumela livumelanisa okuqukethwe kuzo zonke izingxenye ezihlukene zesibonisi se-LED. Lokhu kuvumelanisa kuqeda izinkinga ezifana nokudabula noma ukunensa, ikakhulukazi ekusetheni okukhulu kwe-LED lapho amakhadi atholayo amaningi aphatha izingxenye zesikrini ezihlukene.
d. Ukukhanya Nokulungiswa Kombala
Amakhadi amaningi okuthumela avumela abasebenzisi ukuthi balungise ukukhanya, ukugqama, nezilungiselelo zombala. Lokhu kuvumelana nezimo kubalulekile ekulungiseni isibonisi ezindaweni ezihlukahlukene, njengezikhala zangaphandle noma zasendlini ezinezimo ezihlukene zokukhanya.
3. Izinhlobo zokuthumela amakhadi
Ngokuya ngohlelo lokusebenza nosayizi wokuboniswa kwe-LED, izinhlobo ezimbalwa zamakhadi okuthumela ziyatholakala:
a. Amakhadi Ajwayelekile Wokuthumela
Amakhadi okuthumela ajwayelekile alungele izikrini ze-LED ezincane ukuya kosayizi omaphakathi kanye nezinhlelo zokusebenza eziyisisekelo. Zinikeza imisebenzi ebalulekile njengokudlulisa idatha nokuvumelanisa kodwa zingase zingasekeli ukulungiselelwa okuthuthukisiwe kokufaka okukhulu.
b. Amakhadi Okuthumela Asebenza Kakhulu
Ngezibonisi ezinkulu ze-LED noma izikrini ezinokulungiswa okuphezulu, amakhadi okuthumela asebenza kahle kakhulu anikeza amandla okucubungula aphakeme nokusekelwa kwamanani edatha aphezulu. Avame ukusetshenziswa ezindaweni ezidinga okuqukethwe okunencazelo ephezulu, njengokukhangisa kwangaphandle, amakhonsathi esiteji, nezinkundla zemidlalo.
c. Amakhadi Okuthumela Angenantambo
Amanye amakhadi okuthumela eza nezinketho zokuxhuma okungenantambo, ezinenzuzo ekufakweni lapho ukufaka ikhebula kungenzeki. Zinikeza ukuguquguquka futhi zivumela abasebenzisi ukuthi balawule futhi babuyekeze okuqukethwe bekude.
4. Ulifaka Kanjani Ikhadi Lokuthumela Esibukweni Se-LED
Ukufaka ikhadi lokuthumela kuqondile kodwa kudinga ukunakwa ngokucophelela ukuze kuqinisekiswe ukusebenza okufanele. Nazi izinyathelo eziyisisekelo:
Thola indawo yekhadi lokuthumela kusilawuli noma isidlali semidiya.
Faka ikhadi lokuthumela ngokuqinile endaweni ebekiwe. Qiniseka ukuthi ixhumeke ngokuvikelekile ukuze ugweme ukuphazamiseka kwesignali.
Xhuma isibonisi ekhadini lokuthumela usebenzisa izintambo ezihambisanayo (ngokuvamile i-Ethernet noma i-HDMI).
Lungiselela izilungiselelo ngesofthiwe ehlinzekwa ngumkhiqizi wekhadi lokuthumela. Lesi sinyathelo siqinisekisa ukuthi izilungiselelo zokubonisa, ezifana nokukhanya nokulungiswa, zilungiswa ngokucaciswa kwakho.
Hlola isibonisi ukuze uqinisekise ukuthi zonke izingxenye zesikrini se-LED zisebenza kahle, ngaphandle kwamaphikseli afile, ukunensa, noma ukungahambisani kombala.
5. Izinkinga Ezivamile Ngamakhadi Okuthumela kanye Namathiphu Okuxazulula Inkinga
Ngaphandle kokuthembeka kwawo, ukuthumela amakhadi kwesinye isikhathi kungahlangabezana nezinkinga. Nazi izinkinga ezimbalwa ezivamile nezindlela zokuxazulula inkinga:
a. Asikho Isibonisi noma Isikrini Esimnyama
Hlola ukuxhumana phakathi kwekhadi lokuthumela, ikhompuyutha, namakhadi okwamukela.
Qinisekisa ukuthi ikhadi lokuthumela lifakwe ngokuqinile nokuthi zonke izintambo zixhumeke ngokuphephile.
b. Ikhwalithi Yesithombe Engalungile noma Imibala Ehlanekezelwe
Lungisa izilungiselelo zokubonisa kusofthiwe yekhadi lokuthumela, ugxile ekukhanyeni, ukugqama, nezilungiselelo zombala.
Hlola ukuthi i-firmware yekhadi lokuthumela isesikhathini yini, njengoba abakhiqizi ngezikhathi ezithile bekhipha izibuyekezo ukuze baxazulule izinkinga ezaziwayo.
c. Ukubambezeleka noma Ukubambezeleka Kwesiginali
Qinisekisa ukuthi ikhadi lokuthumela liyahambisana nosayizi wesibonisi sakho se-LED nohlobo.
Ezikrinini ezinkulu, cabanga ukusebenzisa amakhadi okuthumela asebenza kahle kakhulu ukuze uphathe idatha yokucaca okuphezulu ngokushelela.
6. Ukukhetha Ikhadi Lokuthumela Elilungile Lokuboniswa Kwakho Kwe-LED
Lapho ukhetha ikhadi lokuthumela, cabangela izici ezilandelayo ukuze uqinisekise ukuhambisana nokusebenza:
Usayizi Wesikrini Nokulungiswa: Izibonisi ezinokulungiswa okuphezulu ngokuvamile zidinga amakhadi okuthumela asebenza kahle kakhulu.
Indawo Yokufaka: Izibonisi zangaphandle zingase zidinge ukuthumela amakhadi anesimo sezulu esingeziwe noma izici zokuzivikela.
Izidingo Zokulawula: Uma udinga ukulawula isibonisi ukude, bheka amakhadi okuthumela anezinketho zokuxhuma okungenantambo.
Uhlobo Lokuqukethwe: Kumavidiyo anyakazayo noma okuqukethwe okunamandla, tshala ekhadini lokuthumela elisekela amanani aphezulu edatha ukuze udlale kahle.
7. Imicabango yokugcina
Kusistimu yokubonisa ye-LED, ikhadi lokuthumela liyiqhawe elingaqashiwe eliqinisekisa ukuthi okuqukethwe kwakho kulethwa ngokunembile njengoba kuhlosiwe. Ngokuguqula nokudlulisa idatha kahle, igcina ubuqotho bezithombe kuso sonke isikrini, ithuthukisa umuzwa wokubuka wababukeli. Ukuthi ukusetha isibonisi esincane sasendlini noma udonga olukhulu lwe-LED lwangaphandle, ukukhetha nokulungisa ikhadi elifanele lokuthumela kubalulekile ekusebenzeni kahle.
