Ungawabheka kanjani amaphikseli afile ku-TV lapho uthenga futhi usekhaya

Ungawabheka kanjani amaphikseli afile ku-TV – indlela yokubona iphikseli efile nezibani ezingenasici lapho uthenga esitolo nezindlela zokuhlola nokuhlola ekhaya. Ukuboniswa kuma-TV kuwumklamo oyinkimbinkimbi kakhulu, ovame ukuphuka khona kanye efekthri noma esitolo. Ngenxa yalokhu, kufanelekile ukwazi ngenkinga enkulu yawo wonke ama-matrics kuma-TV – amaphikseli aphukile. Lesi sihloko sizoxoxa ngokuthi kuyini, ukuthi ungawabona kanjani, futhi ngaphansi kwaziphi izimo ongazilungisa ngokwakho. Sizophinde sibone ukuthi singayibheka kanjani i-TV ukuthi iyasebenza yini uma uthenga i-TV entsha noma esetshenzisiwe nokuthi iwaranti izosebenza ngaphansi kwaziphi izimo. Hhayi njalo ukungasebenzi kahle ngesikrini kubhekwa njengesizathu sokulungisa mahhala esitolo.

Iyini i-pixel efile ku-Smart TV, ibukeka kanjani ngokujwayelekile

Isibonisi ngasinye sibonisa isithombe sisebenzisa amaphikseli – lawa ama-LED angawodwana akhanya ngokukhanya okuthile. Inombolo yabo enkulu idala umphumela wesithombe esinyakazayo. Zisebenza ngokuzimela komunye nomunye futhi zilawulwa isilawuli. Iphikseli ngalinye linamaphikseli amancane – lawa ama-RGB ama-RGB anemibala ebomvu, eluhlaza okwesibhakabhaka noluhlaza okwesibhakabhaka. Uma ugqamisa le mibala emithathu ngokuhlukile, ungathola noma yimuphi umbala ku-spectrum ebonakalayo kumuntu. Uma ukhanyisa yonke imibala emithathu, uthola umhlophe, futhi uma ucisha – umnyama. Sakheka kanjalo isithombe.
Uma i-pixel yonakalisiwe, ngeke ikhubaze yonke idivayisi, kodwa izodala ichashazi elimnyama esikrinini endaweni eyodwa. Ezinye izinkinga ngephikseli zingayibangela ukuthi ikhanye ngombala owodwa kuphela noma ingavali ngisho noma isithombe simnyama. Ngenxa yalokhu, lapho ubuka amavidiyo, kuzoba nesici sombala ngesikhathi esisodwa, kubukeka kanjena:

Yiziphi izinhlobo zamaphikseli afile aku-TV

I-pixel ingasebenza ngendlela engalindelekile ngenxa yezizathu ezihlukahlukene, kusukela ekongeni izindleko zokukhiqiza kuye kokonakala ngokomzimba ngesikhathi sokuthunyelwa. Kanjalo nje, amaphikseli awakwazi ukuphuka ngisho nangemva kweminyaka eminingi yomsebenzi. Kunezinhlobo ezintathu eziyinhloko zamaphikseli afile, okuyilezi:

1. Indawo emhlophe (igama elidume kakhulu iphikseli eshisayo). I-pixel enjalo inezinkinga nesilawuli, ayiqondi imiyalo yokunikezwa kwamandla kagesi futhi ikhiqiza ubuningi bamanje. Ngenxa yalokhu, i-pixel ishisa kakhulu, futhi lokhu kukhiqiza isithombe esimhlophe. Iphikseli elinjalo lihlala likhanya ngokumhlophe qwa.
2. ichashazi elimnyama . Lena iphikseli efile, ingashisa noma ingatholi imiyalo evela kusilawuli futhi ihlale icishiwe.
3. Ichashazi lombala (igama lesibili liyi-pixel emile). Okunjalo kwakheka lapho elinye lamaphikseli alo (isibani esibomvu, esiluhlaza noma esiluhlaza okwesibhakabhaka) sihluleka. Kulokhu, i-pixel ayikwazi ukuhlanganisa imibala ye-RGB ngokujwayelekile, yingakho ihlale ikhanya ngombala owodwa, noma isichazamazwi sayo sishintshelwa kwenye yephalethi (isibonelo, kufanele kube nokukhanya okuluhlaza, kodwa khomba kuphuzi). Lolu hlobo lomonakalo lungalungiswa uwena.

Ungalihlonza kanjani iphikseli ephukile kuma-TV anamatrices ahlukene

Kuyafaneleka ukucabangela ukuthi kunezinhlobo ezimbili eziyinhloko zama-matrices, okuyizibonisi ze-LCD kanye ne-OLED. Emgogodleni wawo, asebenza ngendlela efanayo, kodwa ama-OLED asathambekele ekushisweni kwe-pixel, okuyilapho isithombe sangemuva sihlala esikrinini uma siphakelwa ku-TV isikhathi eside kakhulu. Isici esinjalo sibonakala ngokubeka isithombe esisodwa kwesinye. Izikrini ze-LCD azinaso lesi sici, ngakho zihlala isikhathi eside. Kunezinhlobo eziningi zama-matrices e-LCD (ama-matrices e-crystal liquid), kodwa izinhlobo zawo azithinti indlela amaphikseli afile atholakala ngayo, anqunywe futhi alungiswe. Uma i-TV ine-IPS, QLED noma i-Nano Cell matrix, lokhu kusho ukuthi i-matrix ye-LCD.

Okubalulekile! Abanye abakhiqizi noma izitolo kwesinye isikhathi bhala uhlobo lwesikrini se-LED. Njengendlela yokukhanyisa ngemuva, empeleni, lawa amatrices ajwayelekile e-IPS.

Ngokuqhubekayo esihlokweni, sizohlaziya indlela yokuhlonza nokulungisa amaphikseli aphukile ku-TV ekhaya noma ukuyibuyisela ngaphansi kwewaranti.

Mangakhi amaphikseli afile avunyelwe ezinhlotsheni ezahlukene ze-matrix

Uma amaphikseli aphukile evela ku-TV, ungayibuyisela esitolo ngaphansi kwewaranti (yebo, uma ingakaphelelwa yisikhathi). Kodwa akuzona zonke iziphambeko zikamatikuletsheni ezithathwa njengamacala ewaranti; kwezinye izimo, ukulungiswa kungase kunqatshelwe. Ngenxa yobunkimbinkimbi bokwenza izikrini, abalawuli baqhamuke nezinga elilawula ukushiyeka okuthile kokukhiqiza futhi livumela inani elincane lamaphikseli afile ukuthi abhekwe njengejwayelekile futhi angekho ngaphansi kwewaranti. Njengoba sitholile ngaphambili, kunezinhlobo ezintathu zamaphikseli afile. Ngamunye wabo ulawulwa ngendlela ehlukile. Wonke ama-TV ahlukaniswe abe amakilasi amane obuchwepheshe, uma izinga eliphezulu liphakeme, kuba ngcono i-matrix kanye nezidingo zawo eziqinile. Nawa amaleveli lapho omatikuletsheni bahlukaniswa khona kuma-TV esimanje:

1. Ikilasi lokuqala – akufanele kube namaphikseli afile nhlobo, noma inombolo yawo encane, inombolo ebalulekile ibhekwa njengesici futhi ihlanganiswe isiqinisekiso. Kwenzeka kuphela kumamodeli abiza kakhulu.
2. Isigaba sesibili amatrices ekhwalithi ephezulu, okuyinto evamile ukuba namaphikseli afile ayishumi nambili. Okujwayelekile kwamagajethi abizayo.
3. Isigaba sesithathu siwuhlobo lwekilasi oluthandwa kakhulu, olunikezwe amamodeli amaningi wesabelomali. Amaphikseli amancane afile avunyelwe, angabonakali empilweni yangempela.
4. Ikilasi lesine ngomatikuletsheni abashibhile anamaphikseli afile abonakalayo. Amaphikseli angasebenzi angu-262 esigidini ngasinye avunyelwe. Akuvamile ukubonakala.

Kunethebula elihlukile elibonisa inani eliqondile lamaphikseli afile okungenzeka ukuthi afile ezigabeni ezahlukahlukene zemishini:

Ukuze unqume inani lawo wonke amaphikseli ku-matrix, udinga ukuphindaphinda ukulungiswa kwesikrini ngokuma ngokulungiswa okuvundlile. Ibhalwe njengamavelu amabili, ahlukaniswa yinkanyezi noma uphawu “X”. Ngokwesibonelo, 1280×720, 1920*1080 nokunye. Kunezinqumo ezintathu eziyinhloko kuma-TV, okungukuthi:

1. I- HD – ukulungiswa okuphezulu, okungamaphikseli angu-1280 x 720, okusho ukuthi lawa ma-TV anamaphikiseli angu-912,600.
2. I- FullHD iwuhlobo oludume kakhulu, olunamachashazi avundlile angu-1920 namachashazi aqondile angu-1080. Le TV inamaphikseli angu-2,073,600.
3. I- 4K iyi-TV yekhwalithi ephezulu kakhulu enokulungiswa okuphezulu kakhulu okwamanje. Inamachashazi avundlile angu-3840 kanye namachashazi aqondile angu-2160. Uma uphindaphinda inani, ungathola ukuthi kukhona amaphikseli ayizigidi ezingu-8.3. Ama-TV ashibhile awahlomekile ngaleli zinga, ngakho-ke kaningi ama-TV abe esekilasini lesibili nangaphezulu.
