Ekufuneni amava okugqibela okubonakalayo namhlanje, itekhnoloji yokubonisa ye-OLED (Organic Light-Emitting Diode) ikhawuleza ibe sisisombululo esithandwayo kwizikrini zezixhobo ze-elektroniki, ngenxa yokusebenza kwayo okugqwesileyo. Ngokungafaniyo nezikrini ze-TFT LCD zemveli, i-OLED isebenzisa umgaqo wokuzikhupha apho i-pixel nganye ivelisa ukukhanya kwayo, isusa imfuneko yemodyuli yokukhanya kwangasemva. Olu phawu luvumela phantse umlinganiselo wokungafani ongapheliyo, amaxesha okuphendula ngokukhawuleza, kunye nomgangatho womfanekiso ocacileyo nocacileyo—iingenelo ezenza ukuba ithandwe kakhulu ngabathandi bezikrini eziphezulu kunye nabasebenzisi abaziingcali.
Okwangoku, iteknoloji ye-OLED yahlulwe kakhulu kwi-PMOLED (Passive Matrix OLED) kunye ne-AMOLED (Active Matrix OLED). Nangona i-AMOLED isetyenziswa kakhulu kwii-elektroniki zabathengi ezifana nee-smartphone, i-PMOLED iyaqhubeka nokuba nendima ebalulekileyo kwizikrini ezincinci ukuya kweziphakathi ngenxa yendlela yayo yokuqhuba eyahlukileyo kunye nokusebenza kwayo okugqwesileyo. Ifanelekile ngokukodwa kwizicelo ezibandakanya izixhobo ezinxitywayo, iiphaneli zolawulo lwemizi-mveliso, kunye neenkqubo ezifakiweyo.
Ubuchwepheshe bokuqhuba busembindini wokufikelela kwizikrini ze-OLED ezikumgangatho ophezulu. Umzekelo, i-SSD1306 driver IC esetyenziswa kakhulu: idibanisa ubuchwepheshe obuninzi obuphambili obungapheleli nje ekusoyiseni imida yezinto kunye neenkqubo kodwa buphucula kakhulu ukwenziwa ngokwezifiso kwemisebenzi yesikrini:
I-Matrix Scanning Drive: Iqhuba ngokufanelekileyo izikrini ze-OLED ezinesisombululo esiphezulu, ilawula ngokulula amashumi amawaka ee-pixels.
I-Constant Current Pixel Drive: Iqinisekisa ulwalamano oluchanekileyo phakathi kokukhanya kunye nombane, ivumela ulawulo oluchanekileyo lwe-grayscale kunye nokukhanya kwizikrini ze-OLED.
Iteknoloji yokutshaja kwangaphambili kunye nokukhupha izibane ngaphambi kokuba zitshajwe: Ijongana nemiba yokukhanya okungalinganiyo kunye nokukhanya okubangelwa yi-parasitic capacitance kwiiphaneli ze-OLED.
Ukucinezelwa kweVolthi ebuyela umva: Kunciphisa ngokufanelekileyo incoko eqhubekayo kwaye kuphucula umahluko kunye nokufana kwizikrini ze-OLED.
Isekethe Yokunyusa Ipompo Yokutshaja: Ibonelela ngevolthi ephezulu efunekayo ekuqhubeni i-OLED, nto leyo eyenza kube lula ukuyila amandla angaphandle.
Ukubhala Okuvunyelanisiweyo Kwisakhelo: Kuthintela ukukrazulwa kwesikrini kwaye kuqinisekisa ukusebenza kakuhle nokuzinzileyo kwesiboniso.
Iindlela ezahlukeneyo zokubonisa: Ixhasa ukubonisa okungaphelelanga, ii-animations eziskrolayo, uhlengahlengiso lomahluko lwamanqanaba angama-256, kunye nezinye iziphumo—zonke zinokucwangciswa ngemiyalelo ukuhlangabezana neemfuno zobuchule kwii-apps ezahlukeneyo ze-OLED.
Nangona iteknoloji ye-OLED isajongene nemingeni yokwandisa ubungakanani bayo ukuya kubukhulu obukhulu kunye nokunciphisa iindleko, izibonelelo zayo ekusebenzeni kombala, isantya sokuphendula, kunye nokusebenza kakuhle kwamandla sele zibonakala. Ngokuqhubeka nokuhlaziywa kobuchwepheshe kunye nokuvuthwa kwekhonkco leshishini, i-OLED kulindeleke ukuba ithathe indawo yemiboniso yekristale yolwelo yendabuko kwiindawo ezikhulayo, inike abasebenzisi amava okubona anzulu nasebenzayo.
Ukukhetha i-OLED akupheleli nje ekukhetheni iteknoloji yokubonisa—kukwamkela ikamva elicacileyo neliqaqambileyo.
