Izinzuzo zezikrini zokukhangisa ze-LED

Ubuchwepheshe be-LED (Light Emitting Diode) basungulwa ngo-1962. Nakuba lezi zingxenye ekuqaleni zazitholakala kuphela ngokubomvu, futhi zazisetshenziswa ngokuyinhloko njengezinkomba kumasekhethi kagesi, ububanzi bemibala namathuba okusebenzisa kwanwebeka kancane kancane kwaze kwaba seqophelweni lapho kungenzeka khona namuhla ithuluzi elibaluleke kakhulu kokubili emkhakheni wokukhangisa nokukhanyisa kwasekhaya.Lokhu kungenxa yezinzuzo eziningi nezibalulekile ezinikezwa ama-LED.

Ukusimama kobuchwepheshe be-LED

Iphuzu lokuqala elivuna imikhiqizo ye-LED umthelela wabo ophansi kwezemvelo - into ebaluleke kakhulu emashumini ambalwa eminyaka adlule.Ngokungafani namalambu e-fluorescent, awanayo i-mercury, futhi akhiqiza ukukhanya okuphindwe kahlanu kune-halogen noma izibani ze-incandescent ukuze zisetshenziswe amandla afanayo.Ukuntuleka kwezingxenye ze-UV kusho nokuthi ukukhanya okukhiqizwayo kuhlanzeke kakhudlwana, kunomphumela omuhle ongaseceleni wokuthi azizihehi izinambuzane.Okunye okufanele ukuqashelwe wukungabi khona kwesikhathi sokufudumala kwama-LED - cishe ziro phansi kuya ku-40° - okusho ukuthi ukukhanya okugcwele kuyenzeka ngokushesha nje lapho ekhanyisa.Okokugcina, isimo esiqinile salobu buchwepheshe sisho imikhiqizo yokugcina enganakekelwa kancane, inciphisa izindleko zayo futhi yandise ubude bayo bempilo.

Izinzuzo zobuchwepheshe be-LED emkhakheni wokukhangisa

Ngokuphathelene nezibonisi ze-LED nezikrini ezinkulu emhlabeni wokukhangisa, lobu buchwepheshe busetshenziswa noma nini lapho isikrini sidinga ukudonsa ukunaka kwababukeli kumkhiqizo othile noma ibhizinisi, noma ukuxhumana ngolwazi oluthile (ngokwesibonelo ukuba khona kwekhemisi eduze, inombolo yezindawo zokupaka mahhala endaweni yokupaka izimoto, izimo zethrafikhi emgwaqweni onguthelawayeka, noma amaphuzu omdlalo wezemidlalo).Kunzima ukweqisa zonke izinzuzo ezitholakala ngokusebenzisa lobu buchwepheshe.

Ngempela, izikrini ezinkulu ze-LED zigcwalisa ngokuphelele umgomo oyinhloko wakho konke ukukhangisa: ukudonsa ukunaka nokuvusa isithakazelo.Ubukhulu, imibala egqamile, egqamile, imvelo eguquguqukayo yezithombe namagama inamandla okudonsa ngokushesha ukunaka kwalabo abadlulayo abaphazamiseke kakhulu.Lolu hlobo lokuxhumana manje selubandakanya kakhulu kunamabhodi ezikhangiso endabuko, amile, futhi okuqukethwe kungashintshwa ngendlela ofisa ngayo ngoxhumo lwe-Wi-Fi.Udinga nje ukwakha okuqukethwe ku-PC, ukulayishe nge-software ezinikele futhi ukuhlele njengoba kudingekile, okungukuthi nquma ukuthi yini ozoyibonisa futhi nini.Le nqubo ivumela ukuthuthukiswa okuphawulekayo kokutshalwa kwezimali.

Amanye amandla ezibonisi ze-LED ukuthi kungenzeka wenze ngendlela oyifisayo umumo nosayizi wazo, okusho ukuthi ubuhlakani bomkhangisi bungavezwa ngokukhululekile, kugqanyiswe ukusebenza komlayezo wabo nokuthola ikhanvasi efanelekile yokuwushayela.

Okokugcina, ukuqina okukhulunywe ngakho ngaphambilini kwemishini ye-LED kunweba ububanzi bawo bokusetshenziswa okungenzeka, njengoba lezi zikrini zingafakwa ngaphandle kokuvikelwa ngisho nalapho kungenzeka zichayeke emanzini kanye nesimo sezulu esibi futhi zimelana nomthelela.

Izikrini ze-LED: ithuluzi elinamandla kakhulu lokuthengisa

Uma sicabanga ngomthelela isikrini se-LED - uma sisetshenziswa ngempumelelo - esingaba nawo ebhizinisini ngokubonakala kanye ne-ROI, kusobala ngokunembile ukuthi simelela kanjani ithuluzi elicishe lidingeke lezokuxhumana kanye nelokumaketha, konke okubaluleke kakhulu njengewebhu eku-inthanethi. ubukhona.Udinga kuphela ukucabanga mayelana nokushesha, ukusebenza kahle kanye nokuguquguquka okukhethekile okungenzeka ngakho ukwazisa noma yikuphi ukuphromotha noma ulwazi ngemikhiqizo emisha, izinsizakalo noma imizamo ethile eqondiswe kulokho okuhlosiwe okukhulunywa ngakho.

Ebhizinisini lendawo, kungenzeka ukukhombisa abadlula ngendlela ukuthi ujabulisa kangakanani umsebenzi, noma ukunaka elinikezela kumakhasimende alo, ngemilayezo yomuntu siqu nezithombe ezidonsa ngokushesha ukunaka kwalabo abaseduze kwesikrini se-LED esifakwe endaweni yayo. izakhiwo.

Emabhizinisini angenazo izitolo ezinkulu, isikrini se-LED singaba uhlobo lwewindi lesitolo elibonakalayo ukukhombisa imikhiqizo ethengiswa ngaphakathi, noma ukukhombisa amasevisi ahlinzekwayo.

Ezingeni likazwelonke, bavame ukuba khona ngaphandle kwezitolo ezinkulu kanye nezikhungo zokuthenga, behlinzeka ngolwazi mayelana namaphromoshini, amahora okuvula njll. kwedolobha, isifunda noma izwe lonke.Amaphosta amakhulu ebhodi lokukhangisa noma amabhanela, enziwe ukuthi asetshenziswe kanye nje, ngokwazi ukuthi imibala yawo izofiphala lapho echayeka elangeni noma esimweni sezulu, ngaleyo ndlela avulela ithuluzi lesimanjemanje, eliphumelelayo nelinenzuzo yezokuxhumana: isikrini sokukhangisa se-LED.

Ekuphetheni, ukusetshenziswa kwezikrini ze-LED, i-totems nezindonga ze-LED kunikeza izinzuzo eziningi, futhi hhayi nje ngokwemibandela yezezimali - nakuba lezi zibonakala ngokushesha - kodwa futhi kusukela ekubukeni kwemvelo nokudala.
