Wake waphawula ukuthiI-LCDIsikrini sibukeka sikhanya uma sibukwa ngqo, kodwa imibala iyashintsha, iyanyamalala, noma inyamalale uma sibukwa nge-engeli? Lesi simo esivamile sivela ekwehlukeni okuyisisekelo kobuchwepheshe bokubonisa, ikakhulukazi phakathi kwezikrini ze-LCD zendabuko kanye nezinto ezintsha ezifana ne-OLED.izibonisi.
Izikrini ze-LCD zithembele kumakristalu acwebezelayo ukulawula ukudlula kokukhanya, zisebenza njengezivalo ezincane. Uma zibukwa ngqo, lawa “ma-shutter” avumelana kahle ukuze akhiqize imibala enembile nokukhanya. Kodwa-ke, uma zibukwa nge-engeli, indlela yokukhanya edlula ungqimba lwekristalu olucwebezelayo iyaphambuka, okuholela ekungalungi kombala kanye nokukhanya okunciphile. Lokhu kuvame ukubizwa ngokuthi “umphumela wokuvala.” Phakathi kwezinhlobo ze-LCD, amaphaneli e-TN abonisa ukushintshashintsha kombala okubi kakhulu, amaphaneli e-VA asebenza kangcono ngokwesilinganiso, kuyilapho amaphaneli e-IPS—ngenxa yokulungiswa kwekristalu olucwebezelayo—anikeza ama-engeli okubuka abanzi kakhulu ngokuphambuka okuncane.
Ngokuphambene nalokho, izikrini ze-OLED ziletha imibala efanayo ngisho noma zisezingeni eliphezulu kakhulu. Lokhu kungenxa yokuthi iphikseli ngayinye kusibonisi se-OLED ikhipha ukukhanya kwayo, isusa isidingo semojuli yokukhanya kwangemuva kanye nengqimba yekristalu eliwuketshezi. Ngenxa yalokho, izikrini ze-OLED zigwema imikhawulo ye-engeli yokubuka etholakala kubuchwepheshe be-LCD. Le nzuzo yenze i-OLED yaba ukukhetha okuthandwayo kwama-smartphone aphezulu kanye namathelevishini aphezulu. Amaphaneli e-OLED esimanje angafinyelela ama-engeli okubuka afinyelela kuma-degree angu-178, agcine ukuthembeka kombala cishe kungakhathaliseki ukuthi umbukeli umi kuphi.
Ngenkathi i-OLEDizibonisiIhamba phambili ekubukeni kwama-engeli, intuthuko kubuchwepheshe be-LED-backlit iyaqhubeka nokubhekana nezinselele ezifanayo. Ubuchwepheshe be-Mini-LED, isibonelo, buthuthukisa izibonisi ze-LED zendabuko ngokufaka ukulawulwa kokukhanya kwangemuva okuhle, okusiza ekunciphiseni ukushintsha kombala kuma-engeli aqondile. Ngaphezu kwalokho, ubuchwepheshe be-quantum dot buthuthukisa ukuhambisana kombala kuwo wonke ama-engeli okubuka abanzi ngokusebenzisa ama-nanomaterials akhipha ukukhanya. Uhlobo ngalunye lokubonisa luhilela ukuguquguquka: ngenkathi amaphaneli e-VA engase abambezeleke ekusebenzeni kokubuka, avame ukusebenza kangcono kunamanye ngesilinganiso sokuqhathanisa.
Kubathengi, ukuhlola ukusebenza kwesikrini kusuka kuma-engeli amaningi kusalokhu kuyindlela esebenzayo yokulinganisa ikhwalithi yephaneli. Izibonisi ezinokushintshashintsha kombala okuncane ngokuvamile zingcono kakhulu, ikakhulukazi emsebenzini wokubambisana noma ukwabelana ngemidiya. Izikrini ze-IPS ne-OLED zivame ukunconywa ezimweni ezinjalo. Ukukhanya kwemvelo nakho kudlala indima—ukukhanya okuphezulu noma okuseceleni kungabhebhethekisa ukuphambuka kombala okubonakalayo. Ukusebenzisa izikhundla ezifanele zokuhlala nokwenza ngcono ukukhanya okuzungezile akugcini nje ngokuqinisekisa ukunemba kombala okungcono kodwa futhi kukhuthaza induduzo yamehlo.
Ngakho-ke ngesikhathi esizayo isikrini sakho sibukeka sihlukile kune-engeli ethile, khumbula—kungase kungabi yiphutha, kodwa isikhumbuzo sobuchwepheshe obusemuva kwesibonisi sakho kanye nokubaluleka kokusethwa kokubukwa okuhle kakhulu.
