Kwilizwe elinamandla leTekhnoloji yokuBonakazelayo, izikrini zokubonisa ezi-LED ziye zaba yiminqweno yendlela eboniswayo kwaye idala amava angenayo. Enye into ebalulekileyo ekuqwalaselweni kwezinto zokukhokelela kukuchonga ubungakanani obulungileyo kwizicelo ezahlukeneyo. Ubungakanani besikrini esibonisa i-LED esidlala indima ebaluleke kakhulu ekuqinisekiseni unxibelelwano olusebenzayo, ukubonakala, kunye nefuthe elipheleleyo. Kweli nqaku, sinenza izinto eziphazamisayoUmboniso we-LEDUbungakanani kwaye unike ukuqonda izigqibo ezinolwazi.
Owokuqala nowokuqala ukuqwalaselwa xa kusenziwa isigqibo seIsikrini se-LEDngumgama wokujonga. Ubudlelwane phakathi kobungakanani besikrini kunye nokujonga umgama kubalulekile ekufezekiseni impembelelo yokubonakalayo. Umzekelo, kwiindawo ezinkulu ezinjengemidlalo okanye iikona zekonisare apho abaphulaphuli bahlala kude nescreen, umboniso omkhulu kubalulekile ukuqinisekisa ukubonakala ngokucacileyo komxholo. Kwelinye icala, kwizithuba ezincinci ezifana nendawo yokuthengisa indawo okanye amagumbi okulawula, ubungakanani besikrini obuphakathi banokwanela.
Enye into ephambili kukusetyenziswa okucetywayo kwesibonisi se-LED. Ngeenjongo zentengiso kunye neenjongo zentengiso, izikrini ezikhulu zihlala zikhethwa ukubamba ingqalelo yabantu abadlulayo kunye nokuhambisa imiyalezo ngokufanelekileyo. Ngokwahlukileyo koko, ngenxa yokuboniswa kolwazi kwizikhululo zeenqwelo moya, izikhululo zolondolozo, okanye useto lwendibaniselwano, ibhalansi phakathi kobungakanani kunye nokusondela kubalulekile ukuqhubela phambili ukufundelwa ngokulula ngaphandle kombukeli.
Isigqibo somboniso we-LED sisikhundla esibalulekileyo esihambelana nobungakanani. Isikrini esikhulu esinesisombululo esiphezulu siqinisekisa ukuba umxholo ubonakala ubukhali kwaye uvutha, nokuba ujonge imigama. Oku kubaluleke kakhulu kwizicelo apho kuboniswa imifanekiso okanye isicatshulwa esineenkcukacha, njengamaziko emiyalelo okanye amagumbi enkomfa. Ukubetha ibhalansi efanelekileyo phakathi kobungakanani kunye nesisombululo kubalulekile ukugcina ingcaciso ebonakalayo.
Yintoni efanele ibe yisayizi ye-LED?
Kubaluleke kakhulu ukwazi ubungakanani be-screen ngelixa ukhetha isisombululo sekrini.
Injongo apha kukuthintela imifanekiso eneenkcukacha ezingafanelekanga okanye izisombululo ezingeyomfuneko (kwezinye iimeko kungahluka ngokuxhomekeka kwiprojekthi). Yipikseli ye-pixel egqiba isisombululo sescreen kwaye inika umgama phakathi kwee-LEDs kwiimilimitha. Ukuba umgama phakathi kwee-LED uyancipha, isisombululo siyanda, ngelixa umgama onyukayo, isisombululo siyancipha. Ngamanye amagama, ukuze ufumane umfanekiso ogudileyo, isikrini esincinci kufuneka sibe sesisombululo esiphezulu (ubuncinci be-43,000 kufuneka sibonise ividiyo esemgangathweni ukuze singaphulukanisi iinkcukacha), okanye isikrini esikhulu, isisombululo kufuneka sincitshiswe kwiiphikseli ezingama-43,000. Ayifanele ilibale ukuba izikrini ze-LED zibonisa ividiyo kumgangatho oqhelekileyo kufuneka ubuncinci zibe ngama-43,000 amaphiko asemzimbeni
Isikrini esikhulu se-LED
Ukuba ufuna ukubeka isikrini esikhulu kwimbono emfutshane (umzekelo, iimitha ezisi-8), sicebisa ukuba sisebenzise isikrini se-LED nge-pixel ebonakalayo. Inombolo ye-pixel ye-pixel ibalwa ngokuphindaphindiweyo i-pixel ye-pixel nge-4. Oku kuthetha ukuba isikrini se-LED sinamaphiko asezimzimbeni angama-50 000 (000) pixels epheleleyo. Ngale ndlela, kwisikrini nge-pixel ebonakalayo, umgama omncinci uncitshisiwe kwisiqingatha xa kuthelekiswa nesikrini nge-pixel yokwenene.
Ukubukela njani ukubukela umgama osondeleyo wokujonga owona mgama umboniseli okufutshane kwisikrini kubalwa nge-hypoteuse.
Ndingabala njani ngokuhlwaya? I-hypotenuse ibalwa yi-Pythagorean Theorem ngolu hlobo lulandelayo:
H² = l² + A²
H: Ukujonga umgama
L: umgama ukusuka kumgangatho ukuya kwiscreen
H: Ukuphakama kwesikrini ukusuka kumgangatho
Umzekelo, umgama ojonga umntu ongu-12m ngaphezulu komhlaba kunye ne-5m kude nescreen kubalwa njenge:
H² = 5º + 12º? H² = 25 + 144? H² = 169? H =? 169? I-13m
Izinto zokusingqongileyo akufuneki zilibale xa kumiselwa ubungakanani besibonisi se-LED. Kwiseto esingaphandle, njengamabhakidi yedijithali okanye izikrini zebala, ubungakanani obukhulu zihlala ziyimfuneko ukubambisa ingqalelo yabaphulaphuli abakhulu. Ukongeza, imiboniso yangaphandle kufuneka ikufanelwe ukumelana neemeko ezahlukeneyo zemozulu, ixhaphaze ngakumbi ukhetho lobungakanani kunye nezixhobo.
Ukuqukumbela, ubungakanani obufanelekileyo kwizikrini zokubonisa i-LED sisigqibo esininzi esixhomekeke kwizinto ezifana nokujonga umgama, ukusetyenziswa kwenjongo, ukusombulula imeko, kunye nokuqwalaselwa kwendalo. Ukuqwalaselwa ngononophelo kwezi zinto kuqinisekisa ukuba i-aprigs ekhethiweyo kunye neemfuno ezithile zesicelo, ehambisa amava abonakalayo afanelekileyo. Njengoko itekhnoloji iyaqhubeka ukuqhubela phambili, ukufumana ibhalansi efanelekileyo phakathi kobungakanani kunye nokusebenza kuya kuba yinto ebalulekileyo ekuhlanganiseni amandla apheleleyoIzikrini zokubonisa ezi-LEDkwimizi-mveliso eyahlukeneyo.
