Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe eminyakeni yamuva, ukuboniswa kwe-LED kuye kwabonwa futhi kwasetshenziswa ezimbonini ezihlukahlukene. Okuqukethwe okubonisiwe kuya ngokuya kuba nencazelo ephezulu. Ungafinyelela kanjani isibonisi se-LEDisibonisi esiphezulu ? Okokuqala, umthombo wesithombe nevidiyo udinga i-HD egcwele. Okwesibili, isibonisi se-LED siyadingeka ukusekela i-HD egcwele. Okwesithathu ukunciphisa ukuphakama kwephikseli yesibonisi se-LED. Okwesine inhlanganisela yesibonisi esiholayo nephrosesa yevidiyo. Njengamanje, izibonisi ze-LED ezinombala ogcwele nazo ziya ekuboniseni okunokucaca okuphezulu.
1, Thuthukisa isilinganiso sokungafani sesibonisi se-LED esinemibala egcwele. Isilinganiso sokuqhathanisa singenye yezinto ezibalulekile ezithinta imiphumela yokubuka. Ngokuvamile, lapho umehluko uphezulu, isithombe sicaca futhi umbala ugqamile. Ukugqama okuphezulu kusiza kakhulu ukucaca kwesithombe nokusebenza kwezinga elimpunga. Kweminye imibhalo nevidiyo enokugqama okukhulu okumnyama nokumhlophe, isibonisi se-LED esinombala ohluke kakhulu sinezinzuzo ngokugqama okumnyama nokumhlophe, ukucijile, nobuqotho. Ukugqama kunomthelela omkhulu kumthelela wokuboniswa wevidiyo eguquguqukayo. Ngenxa yokuthi ukukhanya nobumnyama ezithombeni eziguquguqukayo kuyashesha uma kuqhathaniswa, lapho umehluko uphezulu, kuba lula emehlweni abantu ukuhlukanisa inqubo enjalo yenguquko. Eqinisweni, ukuthuthukiswa kwesilinganiso sokungafani sesikrini esigcwele sombala we-LED ikakhulukazi ukuthuthukisa ukugqama kwesibonisi se-LED esinemibala egcwele kanye nokunciphisa ukukhanya okungaphezulu kwesikrini. Kodwa-ke, ukukhanya akukona okuphakeme ngangokunokwenzeka, kuphezulu kakhulu, kodwa kuyoba okuphambene, hhayi kuphela okuthinta isibonisi se-LED. ukuphila, kodwa futhi kubangele ukungcoliswa ukukhanya. Imojuli ye-LED ye-RGB yesibonisi se-LED kanye neshubhu ekhipha ukukhanya kwe-LED kucutshungulwa okukhethekile, okunganciphisa ukubukeka kwephaneli ye-LED futhi kuthuthukise ukugqama kwesibonisi se-RGB LED.
2, Thuthukisa izinga elimpunga lodonga lwevidiyo ye-LED enombala ogcwele. Ileveli empunga isho ileveli yokukhanya engahlukaniswa kusukela kokumnyama kakhulu kuye kokucwebezela kakhulu ekugqameni kombala owodwa oyinhloko wesibonisi se-LED esinombala ogcwele. Uma iphakama ileveli empunga yesibonisi se-LED esinombala ogcwele, umbala ucebile kanye nombala ogqamile. Ukuthuthukiswa kwezinga elimpunga kungathuthukisa kakhulu ukujula kombala, ukuze izinga lokubonisa lombala wesithombe likhule ngokwejometri. Ileveli yokulawula isikali esimpunga se-LED ngu-14bit~20bit, okwenza imininingwane yeleveli yesithombe nemithelela yokubonisa yemikhiqizo yesibonisi ephezulu ifinyelele ileveli yomhlaba. Ngokuthuthuka kobuchwepheshe behadiwe, isikali esimpunga se-LED sizoqhubeka nokuthuthuka siye ekunembeni okuphezulu kokulawula.
3, Yehlisa ukuphakama kwephikseli yesibonisi se-LED esinemibala egcwele. Ukunciphisa ukuphakama kwephikseli yesibonisi se-LED esinemibala egcwele kungathuthukisa kakhulu ukucaca kwaso. Ukuba kuncane kokuphakama kwechashazi lesibonisi se-LED esinemibala egcwele, kwenza isibonisi sibe sihle. Nokho, intengoizibonisi ze-LED ezine-pitch encane isehlangothini oluphezulu. Ngenhlanhla, imakethe manje ithuthukela ekubonisweni kwe-LED ene-pitch encane.
4, isibonisi se-LED esihlanganiswe nephrosesa yevidiyo. Iphrosesa yevidiyo ye-LED ingasebenzisa ama-algorithms athuthukile ukuze iguqule isignali ngekhwalithi yesithombe ephansi, yenze uchungechunge lokucubungula olufana nokususa phakathi, ukulola umphetho, isinxephezelo sokunyakaza, njll., ukuze kuthuthukiswe imininingwane yesithombe futhi kuthuthukiswe ikhwalithi yesithombe. I-algorithm yokucubungula isikali sesithombe sephrosesa yevidiyo isetshenziswa ukuze kuqinisekiswe ukuthi ngemva kokukalwa kwesithombe, ukucaca kanye nezinga elimpunga lesithombe kugcinwa ngokwezinga elikhulu. Ngaphezu kwalokho, iphrosesa yevidiyo nayo idinga ukuba nezinketho ezicebile zokulungiswa kwesithombe nemiphumela yokulungisa, futhi icubungule ukukhanya kwesithombe, ukugqama, kanye nesikali esimpunga ukuze kuqinisekiswe ukuthi isikrini sikhipha isithombe esithambile nesicacile.
