Kwihlabathi eliguquguqukayo lobuchwephesha obubonakalayo, izikrini zokubonisa i-LED ziye zaba yinto yonke, ziphucula indlela ulwazi oluboniswa ngayo kunye nokudala amava antywilayo. Olunye uqwalaselo olubalulekileyo ekusekweni kwemiboniso ye-LED kukumisela ubungakanani obufanelekileyo bezicelo ezahlukeneyo. Ubungakanani besikrini se-LED sidlala indima ebalulekileyo ekuqinisekiseni unxibelelwano olusebenzayo, ukubonakala, kunye nefuthe elipheleleyo. Kweli nqaku, sihlolisisa izinto ezinempembeleloUmboniso we-LEDUbungakanani kunye nokubonelela ngemibono yokwenza izigqibo ezinolwazi.
Ingqwalasela yokuqala nephambili xa kumiselwa ubungakanani beIsikrini se-LEDngumgama wokujonga. Ubudlelwane phakathi kobungakanani besikrini kunye nomgama wokujonga kubalulekile ekufezekiseni impembelelo yokubona eyona ilungileyo. Umzekelo, kwiindawo ezinkulu ezinje ngamabala emidlalo okanye amabala ekonsathi apho abaphulaphuli behleli kude nescreen, umboniso omkhulu ubalulekile ukuqinisekisa ukubonakala okucacileyo komxholo. Ngokuchaseneyo, kwiindawo ezincinci ezifana neendawo zokuthengisa okanye amagumbi okulawula, ubungakanani beskrini obuphakathi bunokwanela.
Enye into ephambili kukusetyenziswa okujoliswe kuko kwesiboniso se-LED. Ngeenjongo zentengiso nentengiso, izikrini ezinkulu zidla ngokukhethwa ukuba zitsale umdla wabadlula ngendlela kwaye zidlulise imiyalezo ngempumelelo. Ngokwahlukileyo, kwimiboniso yolwazi kwizikhululo zeenqwelomoya, kwizikhululo zikaloliwe, okanye kwizicwangciso zeshishini, ibhalansi phakathi kobukhulu kunye nokuba kufutshane ibalulekile ukuze kube lula ukufundeka lula ngaphandle kokuphazamisa umbukeli.
Isisombululo somboniso we-LED yinkalo ebalulekileyo ehambelana nobukhulu. Isikrini esikhulu esinesisombululo esiphezulu siqinisekisa ukuba umxholo ubonakala ubukhali kwaye udlamkile, nakwimigama ekufutshane yokujonga. Oku kubaluleke kakhulu kwizicelo apho imifanekiso eneenkcukacha okanye okubhaliweyo kuboniswa, njengakumaziko omyalelo okanye kumagumbi enkomfa. Ukubetha ibhalansi elungileyo phakathi kobukhulu kunye nesisombululo kubalulekile ukugcina ukucaca okubonakalayo.
Kufuneka ibe yintoni ubungakanani beskrini esikhokeleyo?
Kubaluleke kakhulu ukwazi ubungakanani besikrini ngelixa ukhetha isisombululo sesikrini.
Injongo apha kukuthintela imifanekiso engacacanga kakuhle okanye izigqibo eziphezulu ngokungeyomfuneko (kwezinye iimeko zinokuhluka ngokuxhomekeke kwiprojekthi). Yipixel pitch emisela isisombululo sesikrini kwaye inike umgama phakathi kwee-LED kwiimilimitha. Ukuba umgama phakathi kwe-LED uyancipha, isisombululo siyanda, ngelixa ukuba umgama ukhula, isisombululo siyancipha. Ngamanye amazwi, ukuze ufumane umfanekiso ogudileyo, isikrini esincinci kufuneka sibe kwisisombululo esiphezulu (ubuncinci be-43,000 pixels bufunekayo ukubonisa ividiyo eqhelekileyo ukuze ungalahleki iinkcukacha), okanye ngokuchaseneyo, kwisikrini esikhulu. , isisombululo kufuneka sincitshiswe ukuya kwi-43,000 pixels. Akufanele ilibale ukuba izikrini ze-Led ezibonisa ividiyo kumgangatho oqhelekileyo kufuneka zibe neepikseli ezibonakalayo ze-43,000 (zokwenyani), kunye nesisombululo esiphezulu sesikrini se-LED kufuneka sibe neepikseli ezibonakalayo ze-60,000 ubuncinane (zokwenene).
Isikrini esikhulu seLed
Ukuba ufuna ukubeka isikrini esikhulu kumbono omfutshane (umzekelo, iimitha ezi-8), sincoma ukuba usebenzise isikrini se-LED nge-pixel ebonakalayo. Inombolo yepixel enenyani ibalwa ngokuphinda-phinda inani lephikseli elibonakalayo ngo-4. Oku kuthetha ukuba ukuba iscreen se-led sineepixels ezingama-50,000 ezibonakalayo (zokwenene) kukho ama-200,000 enyani yepixels zizonke. Ngale ndlela, kwiscreen esinepikseli ebonakalayo, umgama omncinci wokujonga uyancitshiswa ube sisiqingatha xa kuthelekiswa nescreen esinepixel yokwenyani.
Ijongwa Njani iDistaOwona mgama ukufutshane wokujonga ongumgama woyena umbonileyo ukufutshane kwikhusi ubalwa nge hypotenuse.
Ndingayibala njani i-hypotenuse? I-hypotenuse ibalwa ngethiyori yePythagorean ngolu hlobo lulandelayo:
H² = L² + A²
H: Umgama wokujonga
L: Umgama ukusuka kumgangatho ukuya kwesikrini
H: Ubude beskrini ukusuka emgangathweni
Umzekelo, umgama wokubukela womntu oyi-12m ngaphezu komhlaba kunye ne-5m kude nesikrini ubalwa ngolu hlobo:
H² = 5² + 12²? H² = 25 + 144 ? H² = 169 ? H = ?169 ? 13m
Izinto zokusingqongileyo akufuneki zingahoywa xa kumiselwa ubungakanani bomboniso we-LED. Kwiisetingi zangaphandle, ezinje ngeebhilibhodi zedijithali okanye izikrini zesitediyamu, iisayizi ezinkulu zihlala ziyimfuneko ukutsala umdla wabaphulaphuli abaninzi. Ukongeza, iziboniso zangaphandle kufuneka zixhotyiswe ukumelana neemeko zemozulu ezahlukeneyo, zichaphazele ngakumbi ukhetho lobungakanani kunye nezixhobo.
Ukuqukumbela, ubungakanani obufanelekileyo bezikrini zokubonisa i-LED sisigqibo esinamacala amaninzi esixhomekeke kwizinto ezifana nokujonga umgama, ukusetyenziswa okujoliswe kuyo, isisombululo, umlinganiselo wenkalo, kunye nokuqwalaselwa kokusingqongileyo. Ukuqwalaselwa ngokucophelela kwezi zinto kuqinisekisa ukuba ubukhulu obukhethiweyo buhambelana neemfuno ezithile zesicelo, ukuhambisa amava abonakalayo anempembelelo. Njengoko itekhnoloji iqhubela phambili, ukufumana ulungelelwaniso olufanelekileyo phakathi kobukhulu kunye nokusebenza kuya kuba yimfuneko ekusebenziseni amandla apheleleyoIzikrini zokubonisa i-LEDkumashishini ahlukeneyo.
