Ngamanje ama-TV e- LCD aqinile empilweni yethu. Zinama-panel e-LCD, okukhiqizwa ngawo okuthuthukiswa nsuku zonke. Kodwa, naphezu kwalokhu, inkinga yokubukeka kwamaphikseli aphukile esikrinini isalokhu ihlala iphuthumayo.
Ngesikhathi sokuthenga kwe-TV, kunengozi yokuthi uzothola imodeli ngesici esichaziwe. Ukuze ugweme lokhu, kutuswa ukuhlola umqapha wamaphikseli aphukile.
Ihlola isikrini samaphikseli aphukile
I-pixel yincenye encane kunazo zonke zesibonakaliso sokubonisa noma isithombe sedijithali; kubonakala njengento engabonakali enomumo ojikelezayo noma ohlangene. Ngalo, isithombe sakhiwe esikrinini. I-pixel iqukethe ama-subpixel angu-3 emibala emithathu: ebomvu, eluhlaza okwesibhakabhaka nohlaza. Sibonga kubo isibonakaliso sihlukanisa inani elimangalisayo lamathoni ahlukene.
I-pixel ephukile ingazibonakalisa njengephuzu elibonakalayo emlandweni wombala othile. Kunezizathu ezinjalo zokubukeka kwazo:
- ukwehluleka kwe-transistor yokulawula;
- i-subpixel ixhomeke endaweni eyodwa.
Isizathu sokuqala singasuswa kuphela ngosizo lwemishini efanelekile, okungukuthi ngosizo lensiza. Lokhu ngeke kubuyiselwe i-pixel ephukile, kodwa kuyokwenza ingabonakali kancane emehlweni.
Kwesibili, i-pixel ephukile ingabuyiselwa ngokusebenzisa izinhlelo ezikhethekile.
Kodwa, ukuze kungadingeki ukuthi ubheke izindlela zokuxazulula le nkinga, kunconywa ukuba i-matrix ihlolwe ngesikhathi sephikseli ephukile ngesikhathi sokuthenga i-TV.
I-TV noma ukuhlola isheke ngamaphikseli aphukile? Lokhu kungenziwa ngosizo lwezinhlelo ezifanele ngokuxhuma i-TV ku-unit unit noma laptop. Kodwa uma uthenga esitolo, le ndlela inzima ngempela.
Indlela elula kakhulu ukubonisa izithombe ezingemuva zombala esikrinini se-TV. Ngakho, ukudalula iphuzu elimnyama esikrinini, isizinda esimhlophe siphumelele. Ukuthola iphuzu elimhlophe, sebenzisa isizinda esimnyama.
Ukuqhuba ukuhlolwa okunjalo, udinga ukubhala isethi yezithombe ezinemibala enemibala egudini le-flash flash. Indlela engcono kakhulu ukurekhoda amavidiyo wokuhlola.
Le ndlela ifanele ukuhlola izikrini zezinhlobonhlobo ze-TV ezahlukene. Ngokuyinhloko, ngale ndlela ungahlola amaphikseli aphukile ku-Samsung TV.
Ukuhlolwa okuphelele kwesikrini sethelevishini kuzokusiza ukuvimbela ukuthengwa kwemishini engcono empofu eneziphambeko.
