Ukuphonononga iTekhnoloji yokuBonisa i-OLED

Ekufuneni amava abonayo okugqibela namhlanje, i-OLED (i-Organic Light-Emitting Diode) iteknoloji yokubonisa ngokukhawuleza iba sisisombululo esikhethiweyo kwizikrini ze-electronic device, ngenxa yokusebenza kwayo okugqwesileyo. Ngokungafaniyo nezikrini ze-LCD ze-TFT zendabuko, i-OLED isebenzisa umgaqo-siseko wokuzikhupha apho ipikseli nganye ivelisa ukukhanya kwayo, isusa isidingo semodyuli yokukhanya ngasemva. Olu phawu luvumela umlinganiselo womahluko ophantse wangenasiphelo, amaxesha okuphendula ngokukhawuleza, kunye nobukhali, umgangatho womfanekiso ocacileyo-izinto ezilungileyo eziwenza uthandwe kakhulu ngabathandi bomboniso ophezulu kunye nabasebenzisi abaziingcali.

Okwangoku, itekhnoloji ye-OLED yahlulwe kakhulu kwi-PMOLED (Passive Matrix OLED) kunye ne-AMOLED (I-Active Matrix OLED). Ngelixa i-AMOLED isetyenziswa kakhulu kubathengi be-elektroniki njengee-smartphones, i-PMOLED iyaqhubeka nokubamba ukubaluleka okubalulekileyo kwiziboniso ezincinci ukuya kweziphakathi ngenxa yendlela eyahlukileyo yokuqhuba kunye nokusebenza okugqwesileyo. Ilungele ngokukodwa izicelo ezibandakanya izixhobo ezinxitywayo, iipaneli zolawulo lwamashishini, kunye neenkqubo ezifakwe ngaphakathi.

Itekhnoloji yokuqhuba ilele entliziyweni yokufezekisa iziboniso ze-OLED ezikumgangatho ophezulu. Thatha i-SSD1306 yomqhubi we-IC esetyenziswa ngokubanzi njengomzekelo: idibanisa itekhnoloji ephezulu engaphezulu engapheleli nje ngokunempumelelo kwimathiriyeli kunye nemida yenkqubo kodwa iphucula kakhulu ukwenziwa kwemisebenzi yokubonisa:

I-Matrix Scanning Drive: Ngokufanelekileyo iqhuba imiboniso ye-OLED enesombululo ephezulu, ilawula ngokulula amashumi amawaka eepikseli.

I-Pixel yangoku ye-Pixel Drive: Iqinisekisa ubudlelwane phakathi kokukhanya kunye nokwangoku, ivumela i-grayscale echanekileyo kunye nolawulo lokukhanya kwizikrini ze-OLED.

Ukutshaja kwangaphambili kunye neTekhnoloji yokukhupha kwangaphambili: Ukujongana nemiba yokukhanya okungalinganiyo kunye nokukhanya okubangelwa yi-parasitic capacitance kwiipaneli ze-OLED.

I-Reverse Voltage Suppression: Inciphisa ngokufanelekileyo i-crosstalk kwaye iphucule umahluko kunye nokufana kwimiboniso ye-OLED.

I-Charge Pump Boost Circuit: Inika amandla ombane aphezulu afunekayo ekuqhubeni i-OLED, ukwenza lula uyilo lwamandla angaphandle.

Ubhalo oluNxibeleniswayo lwesakhelo: Ikhusela ukukrazuka kwesikrini kwaye iqinisekisa ukusebenza ngokugudileyo kunye nokuzinza okubonakalayo okubonakalayo.

Iindlela zokuBonisa ezahlukeneyo: Ixhasa imiboniso engaphelelanga, i-animations yokuskrola, ulungelelwaniso lomgangatho wama-256, kunye nezinye iziphumo-zonke ziqwalaselwe ngemiyalelo yokuhlangabezana neemfuno zokudala kuzo zonke izicelo ze-OLED ezahlukeneyo.

Nangona itekhnoloji ye-OLED isajongene nemingeni ekunyuseni ubungakanani obukhulu kunye nokunciphisa iindleko, izibonelelo zayo ekusebenzeni kombala, isantya sokuphendula, kunye nokusebenza kakuhle kwamandla sele kubonakala. Ngokuqhubeka kokuphindaphindwa kwetekhnoloji kunye nokuvuthwa kwekhonkco leshishini, i-OLED kulindeleke ukuba ithathe indawo yokubonisa ikristale yolwelo lwemveli kumasimi asakhulayo, inika abasebenzisi amava okuntywila ngakumbi kunye asebenzayo.

Ukukhetha i-OLED ayikuko nje ukukhetha itekhnoloji yokubonisa-kukwamkela ikamva lokucaca kunye nokuqaqamba.
