Intangiriro
Mu buryo bwihuse bwihuta bwitumanaho rya digitale, kwerekana LED murugo byahindutse uburyo bwingenzi mubucuruzi, ibigo byuburezi, amazu yo gusengeramo, hamwe n’ahantu ho kwidagadurira. Kuva hejuru - iherezo ryibyumba byubuyobozi hamwe nibicuruzwa byamamaye bigurishwa kugeza kuri sitidiyo yamamaza imenyekanisha hamwe na centre ya komisiyo ishinzwe imbaraga, ibi byerekanwa bitanga umucyo utagereranywa, amabara meza, hamwe nubunini buke. Nyamara, gushora imari mu nzu LED ntabwo ari imwe - ingano - ihuza - byose. Kimwe mu byemezo bikomeye uzahura nabyo mugihe cyamasoko nogutegura icyiciro ni uguhitamo pigiseli ikwiye.
Pixel ikibanza giteganya neza neza, kureba neza, ingengo yimishinga, hamwe ninyungu rusange kubushoramari. Guhitamo ikibanza kinini cyane kubireba ibidukikije bizavamo ingano, ishusho ya pigiseli idashobora gukurura abumva. Ibinyuranye, guhitamo ikibuga cyiza neza bitari ngombwa birashobora kuzamura cyane ibiciro byumushinga udatanze uburambe bugaragara bwo hejuru.
Kuyobora ubwinshi bwibisobanuro bya tekinike biboneka ku isoko muri iki gihe birashobora kumva bikabije kubayobozi b'ibigo, abahuza AV, na ba nyir'ubucuruzi kimwe. Aka gatabo karambuye gasesengura ibyingenzi bya pigiseli, uburyo bwibanze bwo kumenya neza icyerekezo cyiza cya LED cyo mu nzu, hamwe n’ibintu byingenzi by’ibidukikije, ubukungu, n’ikoranabuhanga ugomba gusuzuma kugira ngo bigerweho neza -.
1. Gusobanukirwa Ikibanza cya Pixel: Icyo aricyo n'impamvu bifite akamaro
Kugira ngo ufate umwanzuro ubimenyeshejwe, umuntu agomba kubanza gusobanukirwa nubusobanuro bwa tekiniki hamwe na fiziki yibanze ya pigiseli. Mubyerekeranye na tekinoroji ya LED igezweho, pigiseli yerekana intera igaragara yapimye muri milimetero kuva hagati ya pigiseli imwe (cyangwa LED pigiseli ya LED) kugeza hagati ya pigiseli yegeranye. Ibipimo bikunze kugaragazwa ninyuguti "P" - urugero, P1.2, P2.5, cyangwa P4.
Amategeko shingiro yintoki agenga pigiseli yoroheje aroroshye: ntoya ya pigiseli ya pigiseli ntoya, niko hafi ya pigiseli yegereye undi, bikavamo ubunini bwa pigiseli ihanitse kandi ikarishye cyane. Ibinyuranye, pigiseli nini isobanura pigiseli nkeya kuri metero kare, ubusanzwe ikwiranye nibidukikije aho abayireba bahagaze kure cyane ya ecran ya ecran.
Isano Hagati ya Pixel Ikibanza no Gukemura
Bitandukanye n’amazi gakondo - yerekana kristu (LCD) cyangwa urumuri kama - rwohereza diode (OLED) ya ecran izana imyanzuro ihamye, itajenjetse, moderi yo mu nzu ya LED yubatswe yubatswe hamwe no guteranya akabati kamwe ka LED cyangwa amatafari hamwe nkibice bya puzzle. Muri rusange imiterere ya ecran ntabwo igenwa gusa nuburinganire bwumubiri bwerekanwe ubwayo, ahubwo ni ihuriro rikomeye ryubunini bwa ecran yumubiri hamwe na pigiseli yatoranijwe.
Iyo ugabanije pigiseli ya pigiseli, wongera cyane umubare wa pigiseli wapakiwe mubice bimwe bifatika. Ubucucike buri hejuru butuma ibishushanyo bigoye, inyandiko nziza, hamwe na - ibisobanuro byerekana amashusho gukora neza nta pigiseli igaragara cyangwa impande zegeranye. Gusobanukirwa iyi sano ni ngombwa kuko kwerekana ibintu byinshi - byo gukemura kuri ecran hamwe na pigiseli nini ya pigiseli isesagura ubudahemuka bwibikoresho byawe, mugihe ushyize hasi - ibyakemuwe kuri ultra - byerekana neza ikibanza gishobora gukurura ibibazo, kugoreka ibihangano, no gukoresha amafaranga adakoreshwa neza.
2. Amabwiriza yibanze hamwe namategeko ya Thumb yo kumenya ikibanza cya Pixel
Guhitamo pigiseli iburyo ntabwo ari ikibazo cyo gukeka; ishingiye ku mahame yashyizweho ya optique, imbonankubone ya acuity yumuntu, hamwe no kureba intera. Kuberako amaso yumuntu afite aho agarukira kubijyanye nuburyo burambuye ashobora gukemura intera runaka, hariho imibare itandukanye yimibare aho pigiseli imwe ihagarara itandukanijwe nijisho ryonyine.
Intera igaragara (Intera ntarengwa)
Intera ntarengwa ntarengwa aho umuntu ufite icyerekezo gisanzwe cya 20/20 ashobora kureba ecran ya LED atabonye pigiseli imwe izwi nkintera ya acuity. Inganda zemewe cyane zo kubara iyi ntera nziza yo kureba muri metero ni:
$$ \\ inyandiko {Pixel Pitch (muri mm)} \\ inshuro 1.16=\\ inyandiko {Intera ntarengwa yo kureba (muri metero)} $$
Ubundi, iyo ukorera mubice byubwami, urundi ruganda rusanzwe ni 10x Itegeko, ryerekana ko milimetero 1 yikibanza cya pigiseli ihwanye na metero 8 kugeza kuri 10 zo kureba intera kugirango isobanuke neza. Kurugero, P2.5 yo mu nzu LED yerekana muburyo bwiza cyane kubareba bahagaze byibura metero 2,5 (hafi metero 8). Niba abayireba begereye kurenza iyi mibare yabazwe, uburambe bugaragara buragabanuka nkuko pigiseli imwe igaragara cyane, igasenya kwibeshya kwishusho ikomeza, idafite ikidodo.
Impuzandengo Ihumure Reba Intera
Mugihe formulaire ya acuity igaragara ibara intera ntarengwa mbere yuko pigiseli ibaho, ihumure ryo kureba intera akenshi ni metero ngirakamaro cyane kubidukikije nyabyo - ibidukikije. Muri dinamike, ndende - umwanya wumuhanda nka lobbi yibigo cyangwa amaduka acururizwamo, abareba bahora bimuka kandi bahindura imyanya. Gushushanya ecran ishingiye gusa kumurongo ntarengwa irashobora gutera umunaniro wamaso no kutamererwa neza mugihe abantu bahagaze hafi mugihe kinini. Abakora umwuga w'inganda bakunze gusaba kugwiza pigiseli ya milimetero kuri milimetero 2 kugeza kuri 2,5 kugirango babone intera ikora neza aho inyandiko n'amashusho bisa nkaho bihujwe rwose, karemano, kandi byoroshye mumaso yumuntu.
3. Ibyingenzi byingenzi bidukikije nibisabwa bigira ingaruka kumahitamo yawe
Mugihe imibare yimibare namategeko ya optique bitanga intangiriro yizewe, ntabwo bavuga inkuru yose. Ahantu hose mu nzu hafite ibintu byihariye biranga umubiri, ibyubatswe byubatswe, hamwe nibikorwa bisabwa bigomba kugira uruhare runini muguhitamo kwanyuma kwa pigiseli kugirango ubone LED yo mu nzu.
Kureba Intera n'Abategera hafi
Imyitwarire yabateze amatwi nubushoferi bwibanze bwa pigiseli yo gutoranya. Reba ikibazo cyambere cyo gukoresha umwanya. Muri sitidiyo yerekana kuri tereviziyo cyangwa icyumba kinini cyo kugenzura -, abakoresha na kamera akenshi baba bashyizwe mumaguru kure yubuso bwa ecran. Kuba hafi bisaba ultra - pigiseli nziza - mubisanzwe kuva kuri P0.9 kugeza P1.8 - kugirango harebwe niba ifoto ya - hejuru ya kamera itababazwa no kurangaza moiré kandi ko abashoramari bashobora gusoma amakuru yuzuye, amadirishya menshi atiriwe bahura nijisho ryamaso.
Ku rundi ruhande, mu cyumba kinini cya hoteri y’amahoteri, inzu nini y’amasosiyete, cyangwa inzu yo gusengeramo, abaterana ubusanzwe bicaye icumi cyangwa se metero amagana uvuye kuri stage. Muri ibi bihe, guhitamo ultra - ikibuga cyiza ntigishobora kubyara umusaruro kandi kirasesagura amafaranga. Icyerekezo cya P3 cyangwa P4 cyo mu nzu kizatanga ishusho idafite ishusho, yuzuye kubateze amatwi ku giciro gito, kuko amaso yumuntu adashobora gukemura itandukaniro ryiza rya pigiseli kuva kure uko byagenda kose.
Ubwoko bwibirimo nibisabwa
Imiterere yibirimo uteganya gutangaza bigira uruhare runini muguhitamo pigiseli. Ibaze ubwawe: Niki kizerekanwa kuri ecran buri munsi?
Ibyatanzwe - Ibirimo Biremereye: Niba ibyerekanwa byawe bizerekana urupapuro rukomeye, urupapuro rwimari rwimari rwimari, igishushanyo mbonera cyububiko, cyangwa itegeko rirambuye - na software - igenzura, ukeneye ubunini bwa pigiseli ndende. Inyandiko ntoya izahinduka, igoreka, kandi idasomeka kuri ecran ya ecran.
Video ya Cinematike na Iyamamaza: Niba iyerekanwa ryeguriwe cyane cyane amashusho yimbere yikirere, imirongo yubuhanzi, hejuru - ingaruka zamamaza ibicuruzwa, cyangwa ibyabaye bizima, ibibanza binini cyane bya pigiseli birashobora kubabarira bidasanzwe kuko amaso yabantu asanzwe avanga ama frame- yimuka yerekana amashusho hamwe no guhinduranya amabara.
Umwanya ugaragara Umwanya nubunini bwa ecran
Ibipimo bifatika byumwanya wawe uhari, ubushobozi bwo gupakira ibintu, hamwe nuburyo bwo gushiraho bishyiraho inzitizi zikomeye kubyo wahisemo. Kuberako LED yerekanwe yubatswe kuva mubunini busanzwe bwabaministre (nka 500mm x 500mm cyangwa 600mm x 337.5mm kugirango igumane ibipimo 16: 9 byuzuye), kugera kumyanzuro yihariye biterwa cyane na pigiseli ya pigiseli. Niba ufite umwanya muto ugereranije - vuga, metero 3 z'ubugari - kandi ukeneye kwerekana imiterere yuzuye ya HD (1920x1080), uhatirwa guhitamo guhitamo ultra - nziza ya pigiseli nziza. Kugerageza kugera kuri HD yuzuye hejuru yumubiri muto ufite ikibuga cya P4 ntibishoboka mumubiri kuko ubunini bwabaminisitiri busabwa kubamo pigiseli 1920 kuri 4mm intera yatuma ecran iba nini cyane mubyumba.
4. Kuringaniza Ingengo yimari, Kubungabunga, no Kuramba mu Ikoranabuhanga
Kuyobora ibisobanuro byerekana LED mu nzu byanze bikunze bikuzana mu masangano yikoranabuhanga ryateye imbere nubukungu bwumvikana. Kubona ahantu heza hagati yimikorere nishoramari ryimari nibyingenzi kugirango bigende neza, birambye.
Ikiguzi Ingaruka Zibyiza bya Pixel
Ni itegeko ridahinduka ryinganda zikora LED ko uko pigiseli igabanuka, igiciro kuri metero kare cyiyongera cyane. Ultra - yerekana neza (nka P0.9 cyangwa P1.2) ipakira inshuro enye LED nyinshi mubice bimwe bisa neza na P2.5. Ubu bwiyongere bukabije bwibice bigize ubwinshi butuma inganda zikora, igipimo cyo gutakaza umusaruro, hejuru - tekinoroji yo kwishyiriraho (SMT) umuvuduko wo gushyira, hamwe nibisabwa na IC.
Kubwibyo, abaguzi bagomba kwirinda kwifata. Ntugahagarike kumwanya muto wa pigiseli iboneka gusa kuko ihagarariye ikoranabuhanga rishya ku isoko. Suzuma intera yawe yo kureba hamwe nibikenewe neza. Niba abakwumva batigera begera metero 4 kuri ecran, kugura P1.2 yerekanwe hejuru ya P2.5 birashobora gukuba kabiri cyangwa gatatu ingengo yimari yawe idatanga inyungu zifatika kumiterere.
Gukwirakwiza Ubushyuhe, Gukoresha Imbaraga, no Kwizerwa
Ubucucike bwibigize nabwo bugira ingaruka kumikorere yibikorwa hamwe nubushyuhe bwumuriro bwerekana.
