Mu nganda zayobowe na LED zerekana, igipimo gisanzwe cyo kugarura no kugarura byinshi byatangajwe n'inganda zisobanurwa nk 1920hz na 384hz llsh ibiciro. Uburyo busanzwe bwo kubishyira mubikorwa ni disiki ebyiri-latch na pwm drive. Imikorere yihariye yigisubizo ahanini ukurikije:

Gahunda yo gutwara ya PWM ifite imvi nyinshi mugihe cyo gukuba kabiri igipimo cyo kuzungura. Imikorere yumuriro uhuriweho na algorithms ikoreshwa mubicuruzwa nibyinshi. Mubisanzwe, umushoferi Chip yegutse ahantu hanini mukarere hamwe nigiciro cyo hejuru.
Ariko, mubihe bya nyuma bya nyuma, uko isi igenda idahungabana, ifaranga hamwe nubundi buryo bwo kuvugurura imikino ya Gray-Extred. Ubwoko bwibipimo byinshi bikunze kuvugwa nkigipimo cya 3k cyongeye guhita umusoro ku ya 3000hz kugirango uhuze na PWM hamwe na 3840hz Umuyoboro wa 3840Hz ukekwaho kuba abaguzi kandi ukekwaho kubabaza abaguzi nibicuruzwa bya Shoddy.
Kuberako mubisanzwe imyanzuro ya 1920x1080 mumwanya werekana yitwa 2k Icyemezo, hamwe nigikorwa cya 3840x2160 nacyo gikunze kwitwa 4k. Kubwibyo, igipimo cya 2880hz gisanzwe kitiranya urwego rwa 3k, nibipimo byiza byishusho bishobora kugerwaho na 3840hz Realresh ntabwo ari gahunda yubunini.
Mugihe ukoresheje Chip ya LIGS LILS nka ecran ya ecran ya ecran, hari uburyo butatu bwingenzi kugirango utezimbere igipimo cyo kugarura ubuyanja:
1. Kugabanya umubare wibishusho-igipimo cyimigabane-imirima:Mu gutamba ubusugire bw'ishusho-igishushanyo, igihe cya buri scan kugirango ndangize kubabara imvi, kugirango inshuro imwe ecran yaka inshuro nyinshi murwego rumwe rwigihe cyo kugarura icyerekezo.
2. Mugabanye ubugari ntarengwa bwa pulse kugenzura kugenzura ibiyobowe:Mugabanye igihe cyagenwe cyakozwe muri rusange, gabanya uruziga rwa Grayscale Kubara buri scan, kandi wongere umubare wigihe ecran yacanye inshuro nyinshi. Ariko, ikibazo cyo gusubiza chip ya shoferi gakondo ntigishobora kugabanuka ukundi, hazaba ibintu bidasanzwe nkubusa cyangwa ibara ryijimye rito.
3. Gabanya umubare wa chip yashoferi uhujwe murukurikirane:Kurugero, mugukoresha umurongo 8-umurongo, umubare wa chice wumushoferi uhujwe nuruhererekane rukeneye kugirango amakuru ashobora kwanduzwa neza mugihe gito cyo gusiba byihuse.
Skingning ecran ikeneye gutegereza amakuru yumurongo ukurikira wandikwa mbere yo guhindura umurongo. Iki gihe ntigishobora kugabanywa (uburebure bwigihe nigereranijwe numubare wa chip), ubundi ecran izerekana amakosa. Nyuma yo gukuramo ibi bihe, iyobowe irashobora gufungura neza. Igihe cyoroshye cyagabanutse, rero mugihe gito (1/60 sec), inshuro zidashobora gucanwa mubisanzwe, kandi igipimo cyo gukoresha gisanzwe, kandi igipimo cyo gukoresha hejuru). Mubyongeyeho, igishushanyo no gukoresha umugenzuzi kibagoye cyane, kandi umurongo wakabumizo wimbere mugutunganya amakuru akeneye kwiyongera, bikaviramo kugabanuka mubikoresho byiza. Byongeye kandi, umubare wibipimo abakoresha bakeneye gukurikirana kwiyongera. Kwitwara neza.
Icyifuzo cyibishushanyo mbonera kumasoko biriyongera umunsi kumunsi. Nubwo ibinyomoro byo mukisho cyo muri iki gihe gifite ikoranabuhanga rya S-PWM, haracyariho icupa ridashobora gucika mu nshingano za scanning. Kurugero, ihame rishinzwe ibikorwa rya Chip ya S-PWM ihari ryerekanwe kumashusho hepfo. Niba chip ya tekinoroji ya S-PWM ikoreshwa mugushushanya 1: 8 gusikana, mubihe bya 16-bit imvi zijimye na pwm kubara inshuro za 16mz, igipimo cyo kugarura ibiboneka ni nka 30hz. Muri 14-bit graycale, igipimo cyo kugarura ubuyanja ni 120hz. Ariko, igipimo cyo kugarura ibiboneka kigomba kuba byibuze hejuru ya 3000hz kugirango wuzuze ibisabwa nijisho ryumuntu kugirango ubone ishusho nziza. Kubwibyo, mugihe agaciro kasabwa nigipimo cyo kuvugurura 3000hz, cyayoboye imirongo mibora hamwe nibikorwa byiza birakenewe kugirango dushyire mubikorwa icyifuzo.
Kuvugurura mubisanzwe bisobanurwa ukurikije integer n time ingano igipimo cya videwo isoko ya 60fps. Muri rusange, 1920hz ni inshuro 32 igipimo cya 60fps. Benshi muribo bakoreshwa muburyo bwo gukodesha, bukaba ari umucyo mwinshi no kugarura ubuyamba. Inama y'Ubutegetsi yerekana incakanango 32 yayoboye IHURIRO RY'IMITERERE Y'INZEMA RUKURIKIRA; 38040hz inshuro 64 igipimo cya 60fps, kandi benshi muribo bakoreshwa ku kibaho cya 64-scan gikozwe kumucyo hamwe numucyo wo hasi no kugarura ubuyambano hejuru.
Ariko, kwerekana module hashingiwe ku gice cya kabiri cyo gutwara abantu 1920hz, gisaba umwanya wo gutunganya ibyuma, gikeneye gucamo ibice byo hejuru y'imikorere y'ibyuma, kandi gikeneye gutamba umubare w'iminzani. Kugoreka no guhungabana.
