Emhlabeni ohlale uvela wobuchwepheshe, impikiswano phakathi kwe-LCD nobuchwepheshe bokubonisa i-OLED iyisihloko esishisayo. Njengomshisekeli wezobuchwepheshe, ngivame ukuzithola ngibambe iqhaza kule mpikiswano, ngizama ukunquma ukuthi ibuphi ubuchwepheshe bokubonisa obunikeza umuzwa ongcono kakhulu wokubonwayo, isikhathi eside, kanye nenani lemali. Kulo mhlahlandlela obanzi, sizohlola ubunkimbinkimbi bazo zombili izibonisi ze-LCD ne-OLED, sihlaziye ukusebenza kwazo ngokwekhwalithi yesithombe, ukunemba kombala, isilinganiso sokungafani, kanye neminyaka yokuphila. Sizophinde sihlole ukusebenza kahle kwazo kwamandla, siqhathanise ukuthi iyiphi kulezi ezimbili evumelana nemvelo. Ngaphezu kwalokho, sizoxoxa ngezindleko zakho zombili lezi zobuchwepheshe, sikusize unqume ukuthi ubuchwepheshe be-OLED obuphezulu bukufanele yini ukutshalwa kwezimali okwengeziwe phezu kwe-LCD ethengekayo. Ekugcineni, umgomo wethu uwukukunikeza ulwazi nemininingwane edingekayo ukuze wenze isinqumo unolwazi ngokuthi ibuphi ubuchwepheshe bokubonisa obufanele izidingo zakho. Sithembe ukuthi sizokuqondisa kule maze yezobuchwepheshe, njengoba sihlola ubuhle nobubi be-LCD nezibonisi ze-OLED.
1. Ukuqonda Ubuchwepheshe: I-LCD nezibonisi ze-OLED
Uma kukhulunywa ngobuchwepheshe bokubonisa, izinhlobo ezimbili zezinhlobo ezisetshenziswa kakhulu i-Liquid Crystal Display (LCD) kanye ne-Organic Light Emitting Diodes (OLED). Umehluko omkhulu phakathi kwalokhu okubili usendleleni ezikhipha ukukhanya.Ama-LCD ancike ekukhanyeni kwangemuvaukukhanyisa amakristalu abo oketshezi, ngenkathiAma-OLED akhipha ukukhanya ngokusebenzisa izinhlanganisela eziphilayo ngazinye.
Nazi izici ezibalulekile zento ngayinye:
* Ama-LCDszithengeka kakhulu futhi zinikeza ukubonakala okungcono elangeni eliqondile. Baphinde basebenzise amandla amancane lapho bebonisa izithombe ezikhanyayo, okuzenza zibe yinketho edumile kumadivayisi afana namakhompyutha aphathekayo nama-smartphone.
* Ama-OLED, ngakolunye uhlangothi, baziwa ngezilinganiso zabo eziphakeme zokungafani nekhono lokubonisa abamnyama bangempela. Lokhu kungenxa yokuthi iphikseli ngayinye kusibonisi se-OLED ikhanya ngokuzimele, okuvumela ukulawula okunembile kwekhwalithi yesithombe. Baphinde banikeze ama-engeli wokubuka abanzi kanye namazinga okuvuselela ngokushesha kunama-LCD.
Kodwa-ke, akukhona nje ngobuchwepheshe uqobo, kodwa nokuthi busetshenziswa kanjani. Isibonelo, ikhwalithi yesibonisi se-LCD ingahluka kakhulu ngokuya ngezinto ezifana nohlobo lwesibani sangemuva esisetshenzisiwe, ikhwalithi yamakristalu awuketshezi, kanye nedizayini ephelele yesibonisi. Ngokufanayo, ukusebenza kwesibonisi se-OLED kungase kuthonywe izici ezifana nekhwalithi yezinto eziphilayo ezisetshenziswayo kanye nokusebenza kahle kwesakhiwo se-pixel.
2. Ukuhlola Ikhwalithi Yesithombe: I-LCD Vs OLED
Enye yezinto ezibaluleke kakhulu okufanele icatshangelwe lapho uqhathanisa izibonisi ze-LCD ne-OLED ikhwalithi yesithombe. Izibonisi ze-OLED zaziwa ngekhono lazo lokuletha amaleveli amnyama ajulile, angathuthukisa kakhulu isilinganiso sokungafani. Lokhu kungenxa yokuthi iphikseli ngayinye kusibonisi se-OLED ingacishwa iyodwa, okuholela kumnyama wangempela kanye nezinga elimangalisayo lemininingwane ezigcawini ezimnyama. Ngakolunye uhlangothi, izibonisi ze-LCD zisebenzisa i-backlight ukuze zikhanyise amaphikseli azo, okungaholela kumazinga amnyama alula kanye nokuhluka okuncane.
Esinye isici okufanele sicatshangelwe ukunemba kombala nokugcwala. Izibonisi ze-OLED ngokuvamile zinikeza i-gamut yombala ebanzi kune-LCDs, okusho ukuthi zingabonisa imibala eminingi nemibala enembe kakhudlwana. Lokhu kungaholela esithombeni esigqamile nesifana nesempilo. Kodwa-ke, abanye abasebenzisi bangathola imibala kusibonisi se-OLED igcwele ngokweqile. Ngokuphambene, izibonisi ze-LCD zivame ukuba nemibala ebukeka njengemvelo kakhudlwana, kodwa kungenzeka zingabi namandla noma zinembile njengalezo ezikusikrini se-OLED.
Ekugcineni, ake sixoxe ngama-engeli wokubuka. Izibonisi ze-OLED zine-engeli yokubuka ecishe iphelele, okusho ukuthi ikhwalithi yesithombe ihlala ingaguquki kungakhathaliseki ukuthi isikrini usibuka ukuliphi izinga. Lokhu kuyinzuzo ephawulekayo ngaphezu kwezibonisi ze-LCD, ezingahlupheka ngenxa yokushintsha kombala nokugqama uma ibukwa nge-engeli. Nawa amaphuzu abalulekile okufanele uwakhumbule:
* Izibonisi ze-OLED zinikeza amazinga amnyama ajulile kanye nezilinganiso eziphezulu zokungafani.
* Izibonisi ze-OLED ngokuvamile zine-gamut yombala ebanzi kune-LCDs.
* Izibonisi ze-OLED zinama-engeli wokubuka acishe aphelele.
* Izibonisi ze-LCD zivame ukuba nemibala ebukeka njengemvelo.
* Izibonisi ze-LCD zingahlushwa amashifu ombala nokugqama uma zibukwa nge-engeli.
3. Ukuhlaziya Ukunemba Kombala: Ukuqhathanisa I-LCD ne-OLED
Ukungena endaweni yokunemba kombala, into ebalulekile kubuchwepheshe bokubonisa, sithola umehluko ohlukile phakathi kwe-LCD ne-OLED. Izibonisi ze-OLED zaziwa ngekhono lazo lokukhiqiza amaleveli amnyama amsulwa, aphumela esilinganisweni esiphezulu sokungafani nemibala egqamile. Lokhu kungenxa yokuthi iphikseli ngayinye kusibonisi se-OLED ikhanya iyodwa, okuvumela ukulawula okunembile phezu kombala nokukhanya. Ngakolunye uhlangothi, izibonisi ze-LCD zisebenzisa i-backlight ukuze zikhanyise amaphikseli azo, okungaholela ekumeleleni okunembe kakhulu kombala, ikakhulukazi kumathoni amnyama. Kodwa-ke, ama-LCD asezingeni eliphezulu anobuchwepheshe obuphambili njenge-Quantum Dot angaqhudelana eduze nama-OLED ngokunemba kombala. Sengiphetha, ngenkathi zombili lezi zobuchwepheshe zinokufaneleka kwazo, izibonisi ze-OLED zivame ukuba nesandla esingaphezulu ngokuya ngokunemba kombala ngenxa yendlela yazo eyingqayizivele yokukhanyisa kwephikseli.
4. Ukuhlola Isikhathi Sokuphila: OLED Vs LCD
Nakuba kokubili izibonisi ze-OLED ne-LCD zinamandla azo ahlukile, isikhathi sokuphila salobu buchwepheshe isici esibalulekile okufanele sicatshangelwe. Izibonisi ze-OLED zaziwa ngemibala yazo egqamile kanye nokumnyama okujulile, kodwa zivame ukwehla ngokuhamba kwesikhathi, ikakhulukazi amaphikseli aluhlaza. Lokhu kungaholela entweni eyaziwa ngele-'burn-in', lapho izithombe ezimile zigxivizwa unomphela esikrinini. Ngakolunye uhlangothi, izibonisi ze-LCD zinesikhathi eside sempilo futhi azijwayele ukushiswa. Kodwa-ke, bangase bahlupheke ngenxa yokwehluleka kwe-backlight noma ukuwohloka kombala ngokuhamba kwesikhathi. Ngakho-ke, ngokwesikhathi sokuphila, i-LCD ingase ibe nomphetho omncane phezu kwe-OLED, kodwa ukukhetha phakathi kwakho kokubili ekugcineni kuncike ezidingweni ezithile zomsebenzisi namaphethini okusebenzisa.
