Sanibonani nonke, siyi-CJTOUCH Ltd., esebenza ngokukhethekile ekukhiqizeni nasekuhleleni imibukiso ehlukahlukene yezimboni .Enkathini yanamuhla yokuthuthuka ngokushesha kobuchwepheshe bolwazi, izimpawu zedijithali ze-LED, njengethuluzi elikhulayo lokukhangisa nolwazi lokusabalalisa ulwazi, kancane kancane liba yingxenye ebalulekile yazo zonke izigaba zokuphila. Lesi sihloko sizokwethula ngokuningiliziwe ukusebenza komkhiqizo, ukucaciswa kobuchwepheshe, izinzuzo kanye nokubi kwezimpawu zedijithali ze-LED, kanye namacala athile okufaka isicelo ekuthengiseni, ezokuthutha, ezemfundo nakweminye imikhakha.
Izimpawu zedijithali ze-LED wuphawu lukagesi olusebenzisa ubuchwepheshe be-LED (light-emitting diode) ukuze kuboniswe ulwazi. Izinkomba zayo zokusebenza eziyinhloko zihlanganisa:
1. Ukukhanya
Ukukhanya kwezimpawu zedijithali ze-LED kuvame ukukalwa "ngama-nits". Izibonisi ze-LED ezinokukhanya okuphezulu zibonakala ngokucacile elangeni eliqondile futhi zifanele ukusetshenziswa ngaphandle. Ngokuvamile, izimpawu ze-LED zangaphandle zidinga ukukhanya okungaphezu kuka-5,000 nits, kuyilapho izimpawu zasendlini zidinga ukukhanya okuphakathi kuka-1,000 no-3,000 nits.
2. Qhathanisa
Ukugqama kubhekisela esilinganisweni sokukhanya phakathi kwezingxenye ezikhanya kakhulu nezimnyama kakhulu zesibonisi. Ukugqama okuphezulu kwenza izithombe zicace kakhudlwana futhi umbhalo ucace. Ukungafani kwezimpawu zedijithali ze-LED kuvamise ukuba phakathi kuka-3,000:1 no-5,000:1, okunganikeza umuzwa omuhle wokubuka.
3. Ukusetshenziswa kwamandla
Izimpawu zedijithali ze-LED zinokusetshenziswa okuphansi kwamandla, ikakhulukazi uma kuqhathaniswa nezibonisi ze-LCD zendabuko. Ukusetshenziswa kwayo kwamandla kuncike kakhulu ekukhanyeni nasesikhathini sokusebenzisa. Ngokuvamile, izimpawu ze-LED zisebenzisa phakathi kwama-watts angu-200-600 ngemitha-skwele ngayinye, kuye ngosayizi wesikrini nokulungiselelwa kokukhanya.
4. Isinqumo
Ukulungiswa kusho inombolo yamaphikseli isibonisi esingaboniswa. Izimpawu zedijithali ze-LED ezinokulungiswa okuphezulu zingabonisa izithombe ezicacile nombhalo. Izinqumo ezijwayelekile zifaka i-P2, i-P3, i-P4, njll. Uma inombolo encane, iphakama ukuminyana kwe-pixel, efanele ukubukwa eduze.
5. Izinga lokuvuselela
Izinga lokuvuselela libhekisela enanini lezikhathi isibonisi esibuyekeza ngayo isithombe ngomzuzwana, ngokuvamile nge-Hertz (Hz). Izinga eliphezulu lokuvuselela linganciphisa ukucwayiza kwesithombe futhi lithuthukise umuzwa wokubuka. Izinga lokuvuselela lezimpawu zedijithali ze-LED ngokuvamile lingaphezulu kuka-1920Hz, elifanele ukudlala okuqukethwe kwevidiyo.
Izinzuzo kanye Nobubi be-LED Digital Signage
Izinzuzo
Ukubonakala okuphezulu: Izimpawu zedijithali ze-LED zingagcina ukubonakala okuhle ngaphansi kwezimo ezihlukahlukene zokukhanya futhi zifanele ukusetshenziswa ngaphandle nangaphakathi.
Ukuvumelana nezimo: Okuqukethwe kungabuyekezwa nganoma yisiphi isikhathi futhi kusekela amafomethi wemidiya amaningi (njengevidiyo, izithombe, umbhalo, njll.) ukuze kuhambisane nezidingo zokukhangisa ezihlukene.
Ukonga amandla nokuvikelwa kwemvelo: Ubuchwepheshe be-LED bunokusetshenziswa kwamandla okuphansi nempilo ende yesevisi, okunciphisa imvamisa yokushintshwa futhi kunciphisa izindleko zokulungisa.
Heha ukunaka: Okuqukethwe okunamandla nemibala egqamile kungaheha ukunaka kwezethameli futhi kuthuthukise ukusebenza kahle kokukhangisa.
Ukubi
.Ukutshalwa kwezimali kokuqala okuphezulu: Izindleko zokuqala zokuthenga nokufaka izimpawu zedijithali ze-LED ziphezulu uma kuqhathaniswa, okungase kube umthwalo kumabhizinisi amancane.
.Izidingo zobuchwepheshe: Kudingeka ochwepheshe abangochwepheshe ukuze kufakwe futhi kulungiswe, okwandisa inkimbinkimbi yokusebenza.
.Umthelela wendawo: Izimpawu ze-LED zangaphandle zingadinga izinyathelo zokuvikela ezengeziwe ngaphansi kwezimo zezulu ezimbi kakhulu (njengemvula enkulu, umoya onamandla, njll.)
Amacala okusebenza wezimpawu zedijithali ze-LED
1. Imboni yokudayisa
Embonini yokudayisa, izimpawu zedijithali ze-LED zisetshenziswa kakhulu ukukhangisa, ukuboniswa komkhiqizo nokukhuthazwa komkhiqizo. Isibonelo, izitolo ezinkulu eziningi nezitolo ezinkulu zifaka izikrini zokubonisa ze-LED emnyango naseduze namashalofu ukuze zibuyekeze ulwazi lokuphromotha ngesikhathi sangempela futhi zihehe ukunaka kwamakhasimende.
2. Imboni yezokuthutha
Embonini yezokuthutha, izimpawu zedijithali ze-LED zisetshenziselwa ukubonisa ulwazi lwethrafikhi yesikhathi sangempela, izibuyekezo zesimo somgwaqo kanye neziqondiso zokuzulazula. Isibonelo, izikhungo zokulawulwa kwethrafikhi emadolobheni amaningi zizosetha izikrini zokubonisa ze-LED emigwaqweni emikhulu nemigwaqo emikhulu ukuze zinikeze izimo zethrafikhi zesikhathi sangempela namathiphu okuphepha.
3. Imboni yezemfundo
Embonini yezemfundo, izimpawu zedijithali ze-LED zisetshenziselwa ukukhangisa kwekhampasi, ukuhlela izifundo kanye nezaziso zomcimbi. Izikole eziningi zenza izikrini zokubonisa i-LED ekhempasini ukuze zibuyekeze izindaba zesikole nolwazi lomcimbi ngesikhathi futhi zandise ukubamba iqhaza kothisha nabafundi.
Njengethuluzi lesimanje lokusabalalisa ulwazi, izimpawu zedijithali ze-LED zidlala indima ebaluleke kakhulu ezimbonini ezihlukahlukene ngokukhanya kwazo okuphezulu, ukugqama okuphezulu kanye nokuguquguquka. Nakuba kunezinselelo ezithile ekutshalweni kwezimali kokuqala kanye nezidingo zobuchwepheshe, umphumela wokukhangisa kanye nokusebenza kahle okulethwayo ekusatshalalisweni kolwazi kuwusizo ngokungangabazeki. Ngokuthuthuka okuqhubekayo kobuchwepheshe, amathuba okusetshenziswa kwezimpawu zedijithali ze-LED azoba banzi.
