Emhlabeni oguquguqukayo wobuchwepheshe obubonakalayo, izikrini zokubonisa ze-LED sezigcwele yonke indawo, okuthuthukisa indlela ulwazi okwethulwa ngayo nokudala ukuzizwisa okujulile. Okunye okucatshangelwayo okubalulekile ekukhipheni izibonisi ze-LED ukunquma usayizi ofanele wezinhlelo zokusebenza ezahlukahlukene. Usayizi wesikrini esibonisiwe se-LED udlala indima ebalulekile ekuqinisekiseni ukuxhumana okusebenzayo, ukubonakala, kanye nomthelela uwonke. Kulesi sihloko, sihlolisisa izici ezinomthelelaIsibonisi se-LEDusayizi futhi unikeze imininingwane ekwenzeni izinqumo ezinolwazi.
Ukucatshangelwa kokuqala nokubalulekile lapho kunqunywa usayizi we-Isikrini se-LEDyibanga lokubuka. Ubudlelwano phakathi kosayizi wesikrini nebanga lokubuka bubalulekile ekuzuzeni umthelela wokubuka ofanele. Isibonelo, ezindaweni ezinkulu ezifana nezinkundla noma izinkundla zekhonsathi lapho izethameli zihlezi kude nesikrini, isibonisi esikhulu sibalulekile ukuze kuqinisekiswe ukubonakala okucacile kokuqukethwe. Ngokuphambene, ezindaweni ezincane ezifana nezindawo zokuthengisa noma amagumbi okulawula, usayizi wesikrini omaphakathi ungase wanele.
Esinye isici esibalulekile ukusetshenziswa okuhlosiwe kwesibonisi se-LED. Ngezinjongo zokukhangisa nezokukhangisa, izikrini ezinkulu zivame ukuncanyelwa ukuze zibambe ukunaka kwabadlulayo futhi zidlulise imilayezo ngempumelelo. Ngokuphambene, ekubonisweni kolwazi ezikhumulweni zezindiza, eziteshini zesitimela, noma kuzilungiselelo zebhizinisi, ibhalansi phakathi kosayizi nokusondelana ibalulekile ukuze kube lula ukufunda ngaphandle kokucindezela isibukeli.
Ukulungiswa kwesibonisi se-LED kuyisici esibalulekile esihlobene nosayizi. Isikrini esikhudlwana esinokulungiswa okuphezulu siqinisekisa ukuthi okuqukethwe kubonakala kubukhali futhi kugqamile, ngisho nasemabangeni aseduze okubuka. Lokhu kubaluleke kakhulu ezinhlelweni zokusebenza lapho kuboniswa khona izithombe ezinemininingwane noma umbhalo, njengasezikhungweni zemiyalo noma emagumbini enkomfa. Ukushaya ibhalansi efanele phakathi kosayizi nokulungiswa kubalulekile ukugcina ukucaca okubonakalayo.
Kufanele Ube Yini Usayizi Wesikrini We-Led?
Kubaluleke kakhulu ukwazi osayizi besikrini ngenkathi ukhetha ukulungiswa kwesikrini.
Inhloso lapha ukuvimbela izithombe ezinemininingwane engalungile noma izinqumo eziphakeme ngokungadingekile (kwezinye izimo zingahluka kuye ngephrojekthi). Ukuphakama kwe-pixel okunquma ukulungiswa kwesikrini futhi kunikeza ibanga phakathi kwama-LED ngamamilimitha. Uma ibanga phakathi kwama-LED liyancipha, ukulungiswa kuyanda, kanti uma ibanga landa, ukulungiswa kuncipha. Ngamanye amazwi, ukuze uthole isithombe esibushelelezi, isikrini esincane kufanele sibe ekulungisweni okuphezulu (kudingeka ubuncane bamaphikseli angu-43,000 ukuze ubonise ividiyo evamile ukuze ungalahlekelwa imininingwane), noma okuphambene nalokho, esikrinini esikhulu. , ukulungiswa kufanele kwehliswe kube amaphikseli angu-43,000. Akufanele kukhohlwe ukuthi izikrini ze-Led ezibonisa ividiyo ngekhwalithi evamile kufanele okungenani zibe namaphikseli abonakalayo angu-43,000 (angempela), futhi usayizi wesikrini se-LED wokucaca okuphezulu kufanele okungenani abe namaphikseli abonakalayo angu-60,000 (angempela).
Isikrini esikhulu se-LED
Uma ufuna ukubeka isikrini esikhulu endaweni emfishane (isibonelo, amamitha angu-8), sincoma ukuthi usebenzise isikrini se-LED esine-virtual pixel. Inombolo yephikseli ebonakalayo ibalwa ngokuphindaphinda inombolo yephikseli ebonakalayo ngo-4. Lokhu kusho ukuthi uma isikrini esiholayo sinamaphikseli aphathekayo angu-50,000 (angempela), kukhona amaphikseli abonakalayo angu-200,000 esewonke. Ngale ndlela, esikrinini esinephikseli ebonakalayo, ibanga elincane lokubuka liyancishiswa libe yingxenye uma kuqhathaniswa nesikrini esinephikseli yangempela.
Uyibuka kanjani i-DistaIbanga lokubuka eliseduze okuyibanga lesibukeli esiseduze ukuya esikrinini libalwa nge-hypotenuse.
Ngingayibala kanjani i-hypotenuse? I-hypotenuse ibalwa nge-theorem ye-Pythagorean kanje:
H² = L² + A²
H: Ibanga lokubuka
L: Ibanga ukusuka phansi kuya esikrinini
H: Ubude besikrini ukusuka phansi
Isibonelo, ibanga lokubuka lomuntu elingu-12m ngaphezu komhlabathi kanye no-5m kude nesikrini libalwa ngokuthi:
H² = 5² + 12²? H² = 25 + 144 ? H² = 169 ? H = ?169 ? 13m
Izici zemvelo akumele zishaywe indiva uma kunqunywa usayizi wesibonisi se-LED. Ezilungiselelweni zangaphandle, njengamabhodi ezikhangiso edijithali noma izikrini zenkundla, osayizi abakhulu bavame ukudingeka ukuze ubambe ukunaka kwezithameli eziningi. Ukwengeza, izibonisi zangaphandle kufanele zihlonyiselwe ukumelana nezimo zezulu ezihlukahlukayo, zibe nomthelela ekukhethweni kosayizi nezinto zokwakha.
Sengiphetha, usayizi olungile wezikrini zokubonisa ze-LED yisinqumo esinezinhlangothi eziningi esincike ezintweni ezifana nebanga lokubuka, ukusetshenziswa okuhlosiwe, ukulungiswa, ukubukeka kwesilinganiselo, nokucatshangelwa kwemvelo. Ukucatshangelwa ngokucophelela kwalezi zici kuqinisekisa ukuthi usayizi okhethiwe uhambisana nezidingo ezithile zohlelo lokusebenza, okuletha okuhlangenwe nakho okubonakalayo okunomthelela. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, ukuthola ibhalansi efanele phakathi kosayizi nokusebenza kuzobaluleka ekusebenziseni amandla apheleleIzikrini zokubonisa ze-LEDezimbonini ezahlukene.
