Adam Kos Izikrini ze-OLED zingatholakala ngosayizi "wesikhwama" uma kwenzeka kumakhalekhukhwini wethu, futhi zikhiqizwa ngamadiagonal amakhulu ngempela afanele amathelevishini. Uma kuqhathaniswa nesikhathi lapho lobu buchwepheshe buqala ukusabalala emhlabeni wonke, kodwa lezo diagonal ezinkulu ziye zaba ishibhile kakhulu, naphezu kokunyuka kwamanani kwamanje. Ngakho-ke yimuphi umehluko phakathi kwe-OLED ocingweni, esabiza kakhulu, ne-OLED ku-TV?
Ama-OLED angama-organic light-emitting diode. Ukunikeza kwabo okuthembekile kokumnyama kubangela ikhwalithi yesithombe iyonke edlula ama-LCD omdabu. Ukwengeza, azidingi izibani zangemuva ze-OLED ezivela kuzibonisi ezisekelwe ku-LCD, ukuze zibe mncane kakhulu.
Igalari yezithombe
Njengamanje, ubuchwepheshe be-OLED bungatholakala nakumadivayisi aphakathi nendawo. Umkhiqizi oyinhloko wama-OLED amancane wamafoni yi-Samsung, asiwatholi kuphela emafonini e-Samsung Galaxy, kodwa futhi kuma-iPhone, ama-Google Pixels noma amafoni e-OnePlus. I-OLED yamathelevishini yenziwa, isibonelo, ngabakwa-LG, abanikeza izixazululo ze-Sony, i-Panasonic noma i-Philips, njll. Kodwa i-OLED ayifani ne-OLED, nakuba ubuchwepheshe bufana, izinto zokwakha, indlela ezikhiqizwa ngayo, njll. kungaholela ekwehlukeni okukhulu.
Kungaba njalo okuthakaselayo
U-Vratislav Holub Okubomvu, okuluhlaza, okuluhlaza okwesibhakabhaka
Isibonisi ngasinye sakhiwe ngezinto ezincane zesithombe ezibizwa ngamaphikseli. Iphikseli ngalinye lakhiwe amanye amaphikseli amancane, ngokuvamile umbala owodwa ngamunye oyinhloko obomvu, oluhlaza okotshani noluhlaza okwesibhakabhaka. Lona umehluko omkhulu phakathi kwezinhlobo ezahlukene ze-OLED. Kumaselula, amaphikseli amancane avamise ukudalwa ngokwehlukana abomvu, aluhlaza okotshani, naluhlaza okwesibhakabhaka. Amathelevishini asebenzisa isangweji se-RGB esikhundleni, abese esebenzisa izihlungi zemibala ukuze akhiqize okubomvu, okuluhlaza okotshani, okuluhlaza okwesibhakabhaka kanye nokumhlophe.

Kalula nje, yonke i-subpixel ku-TV imhlophe, futhi isihlungi sombala kuphela esinquma ukuthi uzowubona muphi umbala. Lokhu kungenxa yokuthi yilokhu okwenza kube nokwenzeka ukunciphisa imiphumela yokuguga kwe-OLED kanjalo nokutubeka kwe-pixel. Njengoba yonke iphikseli iyafana, yonke iminyaka yobudala (futhi iyasha) ngokulinganayo. Ngakho, ngisho noma lonke iphaneli likamabonakude liba mnyama ngokuhamba kwesikhathi, liba mnyama ngokulinganayo yonke indawo.

Icishe ilingane nephikseli
Okubalulekile ngempela kuma-diagonals amakhulu kangaka ukuthi ukukhiqizwa okulula, okuyiqiniso futhi okushibhile. Njengoba ungase uqagele, amaphikseli ocingweni mancane kakhulu kunalawo aku-TV. Njengoba amaphikseli e-OLED abe esekhiqiza ukukhanya kwawo, uma emancane, ukukhanya kuyancipha. Ngokukhanya kwazo okuphezulu, ezinye izinkinga eziningi nazo ziyavela, njengempilo yebhethri, ukukhiqizwa kokushisa okweqile, imibuzo mayelana nokuzinza kwesithombe, futhi ekugcineni, impilo yonke yamaphikseli. Futhi konke lokhu kwenza ukukhiqizwa kwayo kubize kakhulu.
Yingakho futhi ama-OLED kumaselula asebenzisa ukuhlelwa kwephikseli yedayimane, okusho ukuthi esikhundleni segridi yesikwele elula yamaphikseli amancane abomvu, aluhlaza okwesibhakabhaka, kunamaphikseli amancane abomvu naluhlaza okwesibhakabhaka kunombala oluhlaza. Amaphikseli amancane abomvu naluhlaza okwesibhakabhaka abelwane ngawo nalawo aluhlaza angomakhelwane, iso lakho elizwela kakhulu kuwo. Kodwa omakhalekhukhwini baseduze namehlo ethu, ngakho ubuchwepheshe obuyinkimbinkimbi buyadingeka. Amathelevishini siwabuka kude kakhulu, futhi noma ngabe ama-diagonal amakhulu, asiwuboni umehluko ekusetshenzisweni kobuchwepheshe obushibhile ngamehlo ethu.
Kahle futhi kuchazwe kalula
