Ungazijonga njani ipixels ezifileyo kwiTV xa uthenga nasekhaya

Indlela yokukhangela ipikseli efileyo kwiTV – indlela yokubona i-pixel efileyo kunye nezibane ezingabonakaliyo xa uthenga evenkileni kunye neendlela zokuvavanya kunye nokukhangela ekhaya. Iziboniso kwiiTV ziyilo elinzima kakhulu, elihlala liqhekeza ngqo kwi-factory okanye kwivenkile. Ngenxa yoko, kuyafaneleka ukwazi malunga nengxaki ephambili yazo zonke iimatriki kwiiTV – iipikseli ezaphukileyo. Eli nqaku liza kuxubusha ukuba yintoni na, indlela yokuyichonga, kwaye phantsi kweziphi iimeko onokuzilungisa ngokwakho. Siza kuphinda sibone indlela yokujonga i-TV ukuze isebenze xa uthenga iTV entsha okanye esetyenzisiweyo kunye nokuba yeyiphi imeko esebenzayo kwiwaranti. Akusoloko ukungasebenzi kakuhle kwesikrini kuthathwa njengesizathu sokulungiswa kwasimahla kwivenkile.

Yintoni i-pixel efileyo kwi-Smart TV, ikhangeleka njani ngokubanzi

Umboniso ngamnye ubonisa umfanekiso usebenzisa ipixels – ezi zii-LED ezikhanyisa ngesibane esithile. Inani labo elikhulu lidala umphumo womfanekiso ohambayo. Basebenza ngokuzimeleyo omnye komnye kwaye balawulwa ngumlawuli. Ipixel nganye ineepixels ezincinci- ezi ziibhalbhu zeRGB ezinemibala ebomvu, eluhlaza kunye nebhlowu. Ukuba ugqamisa le mibala mithathu ngokwahlukileyo, unokufumana nawuphi na umbala kwibala elibonakalayo emntwini. Ukuba ukhanyisa yonke imibala emithathu, ufumana umhlophe, kwaye ukuba ucima – umnyama. Ngaloo ndlela umfanekiso uyakhiwa.
Ukuba i-pixel yonakele, ayiyi kucima isixhobo sonke, kodwa iya kudala ichaphaza elimnyama kwisikrini kwindawo enye. Eminye imiba enepixel inokubangela ukuba ikhazimle kuphela kumbala omnye okanye ingacimi nokuba umfanekiso umnyama. Ngenxa yoko, xa ubukele iividiyo, kuya kubakho isiphene sombala ngexesha elinye, kubonakala ngathi:

Zeziphi iintlobo zeepikseli ezifileyo kwiTV

I-pixel inokuziphatha ngokungalindelekanga ngenxa yezizathu ezahlukeneyo, ukusuka ekugcinweni kweendleko zokuvelisa ukuya kwiziphene zomzimba ngexesha lokuhambisa. Kanye ngolo hlobo, ipixels ayinakophuka nasemva kweminyaka emininzi yomsebenzi. Kukho iintlobo ezintathu eziphambili zeepikseli ezifileyo, ezizezi:

1. Indawo emhlophe (igama elidumileyo li-pixel eshushu). I-pixel enjalo ineengxaki kunye nomlawuli, ayiyiqondi imiyalelo yokubonelela nge-voltage kwaye ivelise ubuninzi bangoku. Ngenxa yoku, i-pixel itshisa ukuya phezulu, kwaye oku kuvelisa umfanekiso omhlophe. I-pixel enjalo ihlala ikhanya emhlophe eqaqambileyo.
2. ichaphaza elimnyama . Le ipikseli efileyo, inokutshisa okanye ingafumani imiyalelo evela kumlawuli kwaye ihlale icimile.
3. Ichaphaza lombala (igama lesibini yipixel ebambekileyo). Oko kwenziwa xa enye yee-subpixels zayo (ibhalbhu yokukhanya ebomvu, eluhlaza okanye eluhlaza okwesibhakabhaka) ingaphumeleli. Kule meko, i-pixel ayikwazi ukudibanisa imibala ye-RGB ngokuqhelekileyo, yiyo loo nto ihlala ikhanya ngombala omnye, okanye i-accent yayo itshintshelwe kwenye yeepalethi (umzekelo, kufuneka kubekho ukukhanya okuluhlaza, kodwa khomba ityheli). Olu hlobo lomonakalo unokulungiswa ngokwakho.

Uchonga njani ipixel eyaphukileyo kwiiTV ezinematriki ezahlukeneyo

Kuyafaneleka ukuqwalasela ukuba kukho iindidi ezimbini eziphambili zematriki, ezizezi ziboniso ze-LCD kunye ne-OLED. Embindini wabo, basebenza ngendlela efanayo, kodwa ii-OLED zisathambekele ekutshisweni kwepixel, kuxa i-afterimage ihlala kwiscreen ukuba yondliwa kwiTV ixesha elide. Eso siphene sibonakala ngokubeka umfanekiso omnye komnye. Izikrini ze-LCD azinalo olu phawu, ngoko zomelele ngakumbi. Kukho iintlobo ezininzi ze-LCD matrices (i-crystal ye-liquid matrices), kodwa iindidi zazo azichaphazeli indlela iipikseli ezifileyo ezifunyenwe ngayo, zinqunywe kwaye zilungiswe. Ukuba iTV ine-IPS, i-QLED okanye i-Nano Cell matrix, ke le yi-matrix ye-LCD.

Kubalulekile! Abanye abavelisi okanye iivenkile ngamanye amaxesha dwelisa uhlobo lwesikrini se-LED. Njengendlela yokukhanyisa ngasemva, enyanisweni, ezi ziimatriki ze-IPS eziqhelekileyo.

Ukuqhubela phambili kwinqaku, siya kuhlalutya indlela yokuchonga kunye nokulungisa iipikseli ezaphukileyo kwiTV ekhaya okanye ukuyibuyisela phantsi kwewaranti.

Zingaphi iipixels ezifileyo ezivumelekileyo kwiindidi ezahlukeneyo zematrix

Ukuba iipikseli eziphukileyo zivela kwiTV, ungayibuyisela kwivenkile phantsi kwewaranti (ngokuqinisekileyo, ukuba ingekaphelelwa lixesha). Kodwa ayizizo zonke iziphene ezinematriki ezithathwa njengeemeko zewaranti; kwezinye iimeko, ukulungiswa kunokwaliwa. Ngenxa yobunzima bokwenza izikrini, abalawuli baye beza nomgangatho olawula ukusilela kokuvelisa kunye nokuvumela inani elincinci leepikseli ezifileyo ukuba lithathwe njengesiqhelo kwaye lingaxhomekeke kwiwaranti. Njengoko sifumene ngaphambili, kukho iintlobo ezintathu zeepikseli ezifileyo. Ngamnye kubo ulawulwa ngokwahlukileyo. Zonke iiTV zohlulwe zibe ziindidi ezine zetekhnoloji, kokukhona iklasi iphezulu, kokukhona i-matrix engcono kunye neemfuno zayo zingqongqo.
