Embonini yokubonisa ye-LED, isilinganiso esijwayelekile sokuvuselela kanye nezinga eliphakeme lokuqabuleka okumenyezelwe ngumkhakha kuvame ukuchazwa njengamanani okuvuselela ama-1920HZ kanye nama-3840hz ngamanani ngokulandelana. Izindlela ezijwayelekile zokuqalisa ziyi-Drayivu e-Double-Latch ne-Pwm drive ngokulandelana. Ukusebenza okuthize kwesixazululo kungokuhamba ngale ndlela:
[I-Double Latch Driver IC]: I-1920HZ Rate Rate, i-135BIT EBRICE SCAGE SCALE, YOKWENZA ISITOLO SAMAHHALA SAMAHHALA, UMSEBENZI WOKUQALA WOKUQHAWULA KOKUSHINTSHA;
[PWM Driver IC]: Izinga lokuvuselela le-3840hz, okungu-14-164bit Grayscale okuboniswayo, umsebenzi owakhelwe ngaphakathi Ghost Ukuqedwa, ukuqala kwe-voltage ephansi, kanye nemisebenzi yokususa iPixel.
Isikimu sokushayela se-Latter PWM sinokubonisa okumpunga okuthe xaxa esimweni sokuphinda kabili isilinganiso sokuvuselela. Imisebenzi ehlanganisiwe yesekethe kanye nama-algorithms asetshenzisiwe kumkhiqizo kunzima futhi kube nzima ngokwengeziwe. Ngokwemvelo, umshayeli we-chip wamukela indawo enkulu ye-wafer yendawo kanye nezindleko eziphakeme.
Kodwa-ke, enkathini ye-post-ubhubhane, isimo somhlaba wonke singazinzile, ukwehla kwamandla emali ngokweqile, abakhiqizi bezomnotho bangaphandle bafuna ukulungisa izingcindezi zezindleko, futhi empeleni basebenzise isilinganiso samapharamitha angama-320hz, ukushintshana ngezinga lokuvuselela ama-2880hz, nalolu hlobo lwe Izinga lokuvuselela livame ukubizwa ngokuthi isilinganiso sokuqabuleka kwama-3k ukuze sifune ukuqamba amanga okuvuselela ngaphezulu nge-3000hz ukufanisa i-PWM ngesikimu sokushayela sidida abathengi.
Ngoba imvamisa ukulungiswa kwe-1920x1080 ku-Display field ibizwa nge-2K Resolution, futhi isinqumo se-3840x2160 sivame ukubizwa ngokuthi ukulungiswa kwe-4K. Ngakho-ke, isilinganiso sokuvuselela ama-2880hz ngokwemvelo sididekile ngezinga lokuvuselela ama-3k, kanye namapharamitha wekhwalithi yesithombe esingatholwa ngokuvuselela kwangempela kwama-3840hz akuwona umyalo wobukhulu.
Lapho usebenzisa i-Chip Ejwayelekile Yomshayeli we-LED njengohlelo lokusebenza lwesikrini sokuskena, kunezindlela ezintathu eziphambili zokuthuthukisa izinga lokuvuselela okubukwayo lesikrini sokuskena:
1. Yehlisa inani lamasimu aphansi wesithombe seGrey-Scale:Ngokunikela ngokunikela ngobuqotho besilinganiso esimpunga, isikhathi sokuskena ngakunye ukuqedela ukubala okungamampunga kufinyeziwe, ngakho-ke inani lezikhathi isikrini likhanyiswa ngaphakathi kwesikhathi esisodwa sefreyimu ethile.
2. Fushanisa ububanzi be-pulse obuncane ukulawula ukukhishwa kwe-LED:Ngokunciphisa isikhathi se-LED ekhanyayo yekhamu khale, finyeza umjikelezo wokubalwa kwe-grayscale kwiskena ngasinye, futhi wandise inani lezikhathi isikrini sikhanyiswe kaninginingi. Kodwa-ke, isikhathi sokuphendula sama-hips omshayeli wendabuko asikwazi ukwehliswa ngenye indlela, kuzoba nezimo ezingajwayelekile njengokungalingani okumpunga okuphansi noma umbala ophansi ophansi.
3. Khawulela inani lama-chips okushayela axhumeke ochungechungeni:Isibonelo, ekusetshenzisweni kokuskena okungu-8, inani lama-Chips okushayela elixhunywe ochungechungeni ludinga ukukhawulwa ukuze kuqinisekiswe ukuthi idatha ingadluliselwa kahle ngaphakathi kwesikhathi esinqunyelwe sokushintshana okusheshayo.
Isikrini sokuskena sidinga ukulinda imininingwane yomugqa olandelayo ukuthi ubhalwe ngaphambi kokushintsha umugqa. Lesi sikhathi asikwazi ukufinyezwa (ubude besikhathi bulingana nenombolo yama-chip), ngaphandle kwalokho isikrini sizobonisa amaphutha. Ngemuva kokudonswa lezi zikhathi, i-LED ingavulwa ngempumelelo. Isikhathi sokukhanyisa sincishisiwe, ngakho-ke kungakapheli isikhathi sefreyimu (1/60 sec), inani lezikhathi zonke izikena zingavinjelwa ngokujwayelekile lilinganiselwe, futhi izinga lokusetshenziswa kwe-LED aliphezulu (bheka isibalo esingezansi). Ngaphezu kwalokho, ukwakheka nokusetshenziswa kwesilawuli kuba yinkimbinkimbi ngokwengeziwe, futhi i-bandwidth yokucubungula idatha yangaphakathi idinga ukukhuliswa, okuphumela ekunciphiseni ukuqina kwehadiwe. Ngaphezu kwalokho, inani lamapharamitha abasebenzisi abadinga ukuwabheka ngokwanda. Uziphathe ngokungafanele.
Isidingo sekhwalithi yesithombe emakethe siyanda usuku nosuku. Yize ama-chips amanje wokushayela anezinzuzo zobuchwepheshe be-S-PWM, kusene-bhodlela elingeke liphulwe ngokusebenzisa izikrini zokuthwebula. Isibonelo, inqubo yokusebenza ye-S-M-Driver ye-S-CHIP ikhonjiswa kwisibalo esingezansi. Uma i-chip ye-S-PWM yezobuchwepheshe ekhona isetshenziselwa ukuklama isikrini esingu-1: 8 sokuskena, ngaphansi kwemibandela ye-16-bit scale kanye ne-PWM kubalwa imvamisa ye-16mhz, izinga lokuvuselela elibonakalayo lingaba ngu-30hz. Ku-14-bit grayscale, izinga lokuvuselela elibonakalayo lingaba ngu-120hz. Kodwa-ke, isilinganiso sokuqabuleka okubukwayo sidinga okungenani ngaphezulu kwe-3000hz ukufeza izidingo zeso lomuntu ngekhwalithi yesithombe. Ngakho-ke, lapho inani lesidingo senani lokuvuselela elibukwayo lingama-3000hz, ama-chip we-LED driver anemisebenzi engcono ayadingeka ukuze ahlangabezane nesidingo.
Ukuvuselelwa kuvame ukuchazwa ngokuya ngezikhathi ze-Integer N Izilinganiso Uhlaka lwe-Video Source 60fps. Ngokuvamile, ngo-1920HZ izikhathi ezingama-32 isilinganiso samafreyimu angama-60fps. Iningi lazo lisetshenziswa ekubonisweni okuqashisayo, okungukukhanya okuphezulu kanye nenkundla yokuvuselela ephezulu. Ibhodi leyunithi libonisa kumabhodi angama-32 aholwa yiyunithi yeyunithi yamazinga alandelayo; I-3840hz izikhathi ezingama-64 Izinga lamafreyimu angama-60fps, futhi iningi lazo lisetshenziswa kumabhodi eyunithi amayunithi angama-64-scan e-LED ngokukhanya okuphansi kanye nezinga lokuvuselela eliphakeme ekubonisweni kwe-Indoor LED.
Kodwa-ke, imodyuli ebonisiwe ngesisekelo sohlaka lwe-1920HZ DRIVE inyuswa ngenkani ibe ngu-2880hz, oludinga indawo yokusebenza ye-480HZ, idinga ukuhlukana nomkhawulo ophezulu wokusebenza kwehadiwe, futhi idinga ukudela inani lesikali sehadiwe. Ukuhlanekezela nokungazethembi.
