Emhlabeni oguqukayo wobuchwepheshe obubuchwepheshe, izikrini zokubonisa eziholwayo ziye zaqala, ukuthuthukisa indlela imininingwane ethulwa futhi kwakha okuhlangenwe nakho okugxilile. Ukucatshangelwa okubucayi kokuhambisa ama-LED ekhombisa ukunquma usayizi ofanele wezinhlelo zokusebenza ezahlukahlukene. Usayizi wesikrini sokubonisa esiholayo udlala indima ebaluleke kakhulu ekuqinisekiseni ukuxhumana okusebenzayo, ukubonakala, nomthelela ophelele. Kulesi sihloko, singena ezintweni ezinethonyaUkuboniswa kwe-LEDusayizi futhi unikeze imininingwane yokuthola izinqumo ezinolwazi.
Ukucatshangelwa kokuqala nokubaluleke kakhulu lapho kunqunywa usayizi weIsikrini se-LEDibanga lokubuka. Ubudlelwano phakathi kosayizi wesikrini nokubuka ibanga kubalulekile ekufezekiseni umthelela omuhle wokubona. Isibonelo, ezindaweni ezinkulu ezinjengezinkundla zemidlalo noma amakhonsathi ama-Arenas lapho izilaleli zihlala kude nesikrini, isibonisi esikhudlwana kubalulekile ukuze kuqinisekiswe ukubonakala okucacile kokuqukethwe. Ngakolunye uhlangothi, ezikhaleni ezincane ezifana nezindawo zokuthengisa noma amakamelo okulawula, usayizi wesikrini olinganiselayo ungahle akwanele.
Enye into esemqoka ukusetshenziswa okuhlosiwe kwesibonisi se-LED. Ngokukhangisa kanye nezinhloso zokuphromotha, izikrini ezikhudlwana zivame ukukhethwa ngokuthola ukunakwa kwabadlulayo futhi zidlulise imiyalezo ngempumelelo. Ngokuphambene nalokho, ukuthola imibukiso yezikhumulo zezindiza, iziteshi zezitimela, noma izilungiselelo zebhizinisi, ibhalansi phakathi kosayizi nokusondela kubalulekile ukwenza lula ukufundwa okulula ngaphandle kokubuka isibukeli.
Ukulungiswa kwesibonisi se-LED kuyisici esibucayi esihlobene nosayizi. Isikrini esikhudlwana esinokuxazululwa okuphezulu siqinisekisa ukuthi okuqukethwe kubonakala kubukhali futhi kuyabonakala, ngisho nasekubukeni okusondelene nabo. Lokhu kubaluleke kakhulu kwizicelo lapho kuboniswa khona izithombe ezinemininingwane noma umbhalo, njengasezikhungweni zomyalo noma amakamelo engqungquthela. Ukushaya ibhalansi efanele phakathi kosayizi nokuxazululwa kubalulekile ukuze ulondoloze ukucaca okubonakalayo.
Yini okufanele ibe ngosayizi wesikrini?
Kubaluleke kakhulu ukwazi ubukhulu besikrini ngenkathi ukhetha ukulungiswa kwesikrini.
Inhloso lapha ukuvikela izithombe ezinemininingwane engesihle noma izinqumo eziphakeme ngokungadingekile (kwezinye izikhathi kungahluka ngokuya ngephrojekthi). Kuyindlela yePixel enquma ukulungiswa kwesikrini futhi inikeze ibanga phakathi kwama-LED kuma-millimiteters. Uma ibanga phakathi kwama-LEDs liyancipha, isixazululo siyanda, kanti uma ibanga liyanda, isixazululo siyancipha. Ngamanye amagama, ukuze uthole isithombe esibushelelezi, isikrini esincane kufanele sibe sesixazululweni esiphakeme (amaphikseli okungenani angama-43,000 adingekayo ukubonisa ividiyo ejwayelekile ukuze ungalahlisi imininingwane), noma okuphambene nalokho, isixazululo kufanele sincishiswe amaphikseli angama-43,000. Akufanele ikhohlwe ukuthi izikrini eziholwa zibonisa ividiyo ngekhwalithi ejwayelekile kufanele zibe namaphikseli okungenani angama-43,000 (okungokoqobo), nosayizi wesikrini esinezixazululo esiphakeme kufanele okungenani ube namaphikseli angama-60,000 omzimba (angempela).
Isikrini esikhulu se-LED
Uma ufuna ukubeka isikrini esikhulu ukubona okufushane (ngokwesibonelo, amamitha ayi-8), sincoma ukuthi usebenzise isikrini se-LED nge-pixel ebonakalayo. Inombolo ye-pixel ebonakalayo ibalwa ngokuphindaphinda inombolo ye-pixel ebonakalayo ngo-4. Lokhu kusho ukuthi uma isikrini se-LED sinamaphikseli angama-50 000 omzimba (wangempela, kunamaphikseli angama-200,000 angokoqobo aphelele. Ngale ndlela, esikrinini ene-pixel ebonakalayo, ibanga eliphansi lokubuka lincishiswa libe yisigamu ngokuqhathaniswa nesikrini nge-pixel yangempela.
Kubukwa kanjani ibanga eliseduzane lokubuka eliseduze okuyibanga lesibukeli esiseduze esikrinini kubalwa yi-hypotenuse.
Ngingawabala kanjani i-hypotenuse? I-hypotenuse ibalwa yiPythagorean theorem ngale ndlela elandelayo:
H² = l² + A²
H: Ukubuka ibanga
L: ibanga ukusuka phansi kuya esikrinini
H: Ukuphakama kwesikrini kusuka phansi
Isibonelo, ibanga lokubuka komuntu 12m ngaphezulu komhlaba kanye ne-5m kude nesikrini kubalwa njenge:
H² = 5² + 12²? H² = 25 + 144? H² = 169? H =? 169? 135O
Izici zezemvelo akumele zinganakwa lapho zinquma usayizi wesibonisi se-LED. Kuzilungiselelo zangaphandle, njengamabhodi edijithali noma izikrini ze-instaum, amasayizi amakhulu ngokuvamile adingekayo ukubamba ukunaka kwezithameli ezikhudlwana. Ngokwengeziwe, ukuboniswa kwangaphandle kumele kuhlonyelwe ukumelana nezimo zezulu ezahlukahlukene, kuthonya okunye ukukhethwa kosayizi nezinto zokwakha.
Ekuphetheni, usayizi ofanele wezikrini zokubonisa eziholwayo yisinqumo esiminyene esincike ezintweni ezifana nokubuka ibanga, ukusetshenziswa okuhlosiwe, ukulungiswa, isilinganiso esithile, isilinganiso sezemvelo, kanye nokucatshangelwa kwemvelo. Ukucatshangelwa ngokucophelela kwalezi zinto kuqinisekisa ukuthi usayizi okhethiwe uqondanisa nezidingo ezithile zohlelo lokusebenza, ukuletha okuhlangenwe nakho okubonakalayo okunomthelela. Njengoba ubuchwepheshe buqhubeka buqhubekisela phambili, ukuthola ibhalansi efanele phakathi kosayizi nokusebenza kuzoba lubalulekile ekuhlanganiseni amandla aphelele weIzikrini zokubonisa ze-LEDngaphesheya kwezimboni ezahlukahlukene.
