Gushakisha ikoranabuhanga rya OLED Ecran

Mu gushaka ubunararibonye buhebuje muri iki gihe, ikoranabuhanga ryo kwerekana OLED (Organic Light-Emitting Diode) ririmo guhinduka igisubizo gikunzwe cyane ku bikoresho by'ikoranabuhanga, bitewe n'imikorere yaryo myiza. Bitandukanye na ecran za TFT LCD zisanzwe, OLED ikoresha ihame ryo kwishyiramo aho buri pixel ikora urumuri rwayo, bigatuma hatabaho gukenera module y'urumuri rw'inyuma. Iyi miterere ituma habaho ikigereranyo cy'itandukaniro kitagira iherezo, igihe cyo gusubiza vuba, n'ubwiza bw'ishusho butyaye kandi bugaragara - ibyiza bituma ikundwa cyane n'abakunzi ba ecran bo ku rwego rwo hejuru n'abayikoresha babigize umwuga.

Muri iki gihe, ikoranabuhanga rya OLED rigabanyijemo ibice bibiri: PMOLED (Passive Matrix OLED) na AMOLED (Active Matrix OLED). Nubwo AMOLED ikoreshwa cyane mu bikoresho by'ikoranabuhanga nka telefoni zigendanwa, PMOLED ikomeje kugira akamaro kanini mu bikoresho bito kugeza ku biciriritse bitewe n'uburyo bwayo bwo gutwara ibintu budasanzwe n'imikorere myiza cyane. Ikwiriye cyane cyane porogaramu zirimo ibikoresho byo kwambara, imashini zigenzura ibikoresho mu nganda, na sisitemu zishyirwamo ibikoresho.

Ikoranabuhanga ryo gutwara imodoka ni ryo shingiro ryo kugera ku mashusho meza ya OLED. Dufate urugero rwa SSD1306 driver IC ikoreshwa cyane: ihuza ikoranabuhanga rigezweho ritagabanya gusa imbogamizi ku bikoresho no ku mikorere ariko nanone rikongera cyane ubushobozi bwo guhindura imikorere ya ecran:

Matrix Scanning Drive: Itwara neza ecran za OLED zifite ubushobozi bwo hejuru, igenzura byoroshye pixel ibihumbi mirongo.

Disiki ya Pixel y'Umuriro Uhoraho: Igenzura isano iri hagati y'urumuri n'umuriro, bigatuma habaho kugenzura neza urumuri n'urumuri kuri ecran za OLED.

Ikoranabuhanga ryo gushyira umuriro mbere y'uko usohoka: Rikemura ibibazo by'urumuri rudahuye n'urumuri ruterwa n'ubushobozi bwa parasite mu ma paneli za OLED.

Guhagarika Voltage: Bigabanya neza uburyo bwo kuvugana hagati y'amajwi kandi bikongera uburyo bwo gutandukanya amashusho no kuyahuza mu mashusho ya OLED.

Umuyoboro wo kongera ingufu za charge pump: Utanga ingufu nyinshi zikenewe kugira ngo OLED igende neza, byoroshya imiterere y'ingufu zo hanze.

Kwandika mu buryo bwa "Frame Synchronized": Birinda gucika kwa ecran kandi bigafasha kwerekana neza kandi neza.

Uburyo butandukanye bwo kwerekana amashusho: Ishyigikira kwerekana ibice, animasiyo yo gusimbuka, guhindura itandukaniro ry’urwego rwa 256, n’izindi ngaruka—byose bishobora guhindurwa binyuze mu mabwiriza kugira ngo bihuze n’ibikenewe mu guhanga udushya muri porogaramu zitandukanye za OLED.

Nubwo ikoranabuhanga rya OLED rigihura n’imbogamizi mu kwagura ingano nini no kugabanya ikiguzi, ibyiza byaryo mu mikorere y’amabara, umuvuduko wo gusubiza, no gukoresha ingufu neza biragaragara. Hamwe n’impinduka zikomeje mu ikoranabuhanga no mu iterambere ry’uruhererekane rw’inganda, OLED byitezwe ko izasimbura ecran zisanzwe za crystal zikozwe mu mazi mu nzego zigenda zizamuka, igaha abayikoresha ubunararibonye bwiza kandi bunoze bwo kureba.

Guhitamo OLED si uguhitamo ikoranabuhanga ryo kwerekana gusa—ni ukwitabira ahazaza h’ubuhanga n’ubuhanga.
