Kwishishini lokubonisa i-LED, izinga lokuhlaziya eliqhelekileyo kunye nezinga eliphezulu lokuhlaziya elibhengezwe lishishini lihlala lichazwa njenge-1920HZ kunye ne-3840HZ amazinga okuhlaziya ngokulandelanayo. Iindlela eziqhelekileyo zokuphunyezwa zi-double-latch drive kunye ne-PWM drive ngokulandelanayo. Ukusebenza okuthe ngqo kwesisombululo ikakhulu ngolu hlobo lulandelayo:
[I-IC yomqhubi we-latch ephindwe kabini]: ireyithi yokuhlaziya ye-1920HZ, i-13Bit ibonisa isikali esingwevu, umsebenzi wokuphelisa isiporho, umsebenzi wokuqalisa umbane ophantsi ukususa ipixels ezifileyo kunye neminye imisebenzi;
[I-IC yomqhubi we-PWM]: 3840HZ izinga lokuhlaziya, i-14-16Bit grayscale display, eyakhelwe-ngaphakathi umsebenzi wokuphelisa isiporho, ukuqalisa kombane ophantsi, kunye nemisebenzi yokususa ipixel efileyo.
Iskimu sokuqhuba se-PWM samva sinokucaca ngakumbi kwisikali esingwevu kwimeko yokuphinda kabini isantya sokuhlaziya. Imisebenzi yesekethe edibeneyo kunye ne-algorithms esetyenziswe kwimveliso inzima ngakumbi. Ngokwemvelo, i-chip yomqhubi ithatha indawo enkulu yeyunithi ye-wafer kunye neendleko eziphezulu.
Nangona kunjalo, kwixesha lasemva kobhubhani, imeko yehlabathi ayizinzanga, ukunyuka kwamaxabiso kunye nezinye iimeko zoqoqosho zangaphandle, abavelisi be-LED bafuna ukuphelisa uxinzelelo lweendleko, kwaye baqalise i-3K yokuhlaziya iimveliso ze-LED, kodwa ngokwenene sebenzisa i-1920HZ yokuvuselela i-gear-edge trigger driver. chip Iskimu, ngokunciphisa inani leendawo zokulayishwa kwe-grayscale kunye nezinye iiparameters ezisebenzayo kunye nezalathisi zokusebenza, ngokutshintshiselana ne-2880HZ yezinga lokuhlaziya, kwaye olu hlobo lwezinga lokuhlaziya lubizwa ngokuba yi-3K yezinga lokuhlaziya ukubanga ngobuxoki izinga lokuhlaziya ngasentla. I-3000HZ ukufanisa i-PWM kunye nexabiso le-3840HZ lokwenene lokuhlaziya Inkqubo yokuqhuba idibanisa abathengi kwaye ikrokrelwa ukuba idibanise uluntu ngeemveliso ezinqabileyo.
Kuba ngokuqhelekileyo isisombululo se-1920X1080 kwindawo yokubonisa ibizwa ngokuba yi-2K isisombululo, kwaye isisombululo se-3840X2160 sikwabizwa ngokuba yi-4K isisombululo. Ke ngoko, inqanaba lokuhlaziya le-2880HZ libhidekile ngokwendalo ukuya kwinqanaba lokuhlaziya i-3K, kwaye iiparamitha zomgangatho womfanekiso onokuthi uphunyezwe yi-3840HZ yokuhlaziya ayingomyalelo wobukhulu.
Xa usebenzisa i-chip ye-LED yomqhubi jikelele njengesicelo sesikrini sokuskena, kukho iindlela ezintathu eziphambili zokuphucula izinga lokuhlaziya elibonakalayo kwesikrini sokuskena:
1. Nciphisa inani lemimandla engwevu yomfanekiso:Ngokuncama imfezeko yomfanekiso ongwevu-scali, ixesha lokuskena ngalunye ukugqibezela ukubala kwegreyi-scale liyafinyezwa, ukuze inani lamaxesha isikrini silayitiwe ngokuphindaphindiweyo ngaphakathi kwexesha lesakhelo esinye sinyuswe ukuphucula isantya sokuhlaziya umbono.
2. Nciphisa obona bubanzi buncinci be-pulse ukulawula ukuqhutywa kwe-LED:ngokunciphisa ixesha lentsimi elikhanyayo le-LED, nciphisa umjikelo wokubala kwe-grayscale kwiskena ngasinye, kwaye ukwandisa inani lamaxesha isikrini silayita ngokuphindaphindiweyo. Nangona kunjalo, ixesha lokuphendula kwiitshiphusi zomqhubi zemveli alinakuncitshiswa Kungenjalo, kuya kubakho izinto ezingaqhelekanga ezinje ngokungalingani okuphantsi okanye ukuphoswa kombala ongwevu.
3. Nciphisa inani letshiphusi zomqhubi eziqhagamshelwe kuthotho:Umzekelo, ekusetyenzisweni kwe-8-line scanning, inani leetshiphusi zomqhubi ezidityaniswe kuluhlu kufuneka zikhawulelwe ukuze kuqinisekiswe ukuba idatha inokuhanjiswa ngokuchanekileyo ngaphakathi kwexesha elilinganiselweyo lotshintsho olukhawulezayo lokuskena phantsi kwezinga eliphezulu lokuhlaziya.
Isikrini sokuskena kufuneka silinde idatha yomgca olandelayo ukuba ibhalwe ngaphambi kokutshintsha umgca. Eli xesha alinakuncitshiswa (ubude bexesha bulingana nenani leetships), ngaphandle koko isikrini siya kubonisa iimpazamo. Emva kokutsala la maxesha, i-LED inokuvulwa ngokufanelekileyo. Ixesha lokukhanyisa lincitshisiwe, ngoko ke ngaphakathi kwexesha lesakhelo (1/60 sec), inani lamaxesha apho zonke izikena zinokukhanyiswa ngokuqhelekileyo zilinganiselwe, kwaye izinga lokusetyenziswa kwe-LED aliphezulu (jonga umfanekiso ongezantsi). Ukongezelela, ukuyila kunye nokusetyenziswa komlawuli kuya kuba nzima ngakumbi, kwaye i-bandwidth yedatha yangaphakathi kufuneka inyuswe, okubangelwa ukuhla kozinzo lwe-hardware. Ukongeza, inani leeparamitha ekufuneka abasebenzisi babeke iliso liyanda. Ukuziphatha ngokungaqhelekanga.
Imfuno yomgangatho wemifanekiso kwimarike iyanda imihla ngemihla. Nangona iitshiphusi zomqhubi zangoku zineengenelo zetekhnoloji ye-S-PWM, kusekho i-bottleneck engenakophulwa ekusetyenzisweni kwezikrini zokuskena. Ngokomzekelo, umgaqo wokusebenza we-chip yomqhubi we-S-PWM okhoyo uboniswe kumzobo ongezantsi. Ukuba i-chip ye-S-PWM yomqhubi weteknoloji ekhoyo isetyenziselwa ukuyila isikrini sokuskena se-1: 8, phantsi kweemeko ze-16-bit grey scale kunye ne-PWM yokubala i-frequency ye-16MHz, izinga lokuhlaziya elibonakalayo malunga ne-30Hz. Kwi-14-bit grayscale, izinga lokuhlaziya elibonakalayo limalunga ne-120Hz. Nangona kunjalo, izinga lokuhlaziya elibonakalayo kufuneka libe ngaphezulu kwe-3000Hz ukuhlangabezana neemfuno zeliso lomntu kumgangatho wesithombe. Ke ngoko, xa ixabiso lemfuno yenqanaba lokuhlaziya elibonakalayo liyi-3000Hz, iitshiphusi zomqhubi we-LED ezinemisebenzi engcono ziyafuneka ukuhlangabezana nemfuno.
Uhlaziyo ludla ngokuchazwa ngokwenani elipheleleyo n amaxesha esakhelo somthombo wevidiyo 60FPS. Ngokubanzi, i-1920HZ ngamaxesha angama-32 umlinganiselo wesakhelo se-60FPS. Uninzi lwazo lusetyenziswe kwisiboniso sokurenta, esinebala elikhanyayo kunye nokuhlaziya okuphezulu. Ibhodi yeyunithi ibonisa kwiibhodi zeyunithi ze-32 zokuskena ze-LED zamanqanaba alandelayo; I-3840HZ ngamaxesha angama-64 umlinganiselo wesakhelo se-60FPS, kwaye uninzi lwazo lusetyenziswa kwi-64-scan iibhodi zeeyunithi ze-LED ezinokukhanya okuphantsi kunye nezinga eliphezulu lokuhlaziya kwimiboniso ye-LED yangaphakathi.
Nangona kunjalo, imodyuli yokubonisa ngesiseko se-1920HZ isakhelo se-drive inyuswe ngenkani ukuya kwi-2880HZ, efuna indawo yokucubungula i-hardware ye-4BIT, idinga ukunqumla umda ophezulu wokusebenza kwe-hardware, kwaye idinga ukunikela ngenani le-gray scales. Ukugqwetheka kunye nokungazinzi.
