I-LED vs LCD Display: Umehluko Oyinhloko, Izinzuzo, futhi Ikuphi Okungcono?

1. Iyini i-LED, i-LCD?

I-LED imele i-Light-Emitting Diode, idivayisi ye-semiconductor eyenziwe ngezinhlanganisela eziqukethe izakhi ezifana ne-Gallium (Ga), i-Arsenic (As), i-Phosphorus (P), ne-Nitrogen (N). Lapho ama-electron ehlangana futhi nezimbobo, akhipha ukukhanya okubonakalayo, okwenza ama-LED asebenze kahle kakhulu ekuguquleni amandla kagesi abe amandla okukhanya. Ama-LED asetshenziswe kabanzi ekuboniseni nasekukhanyiseni.

I-LCD, noma i-Liquid Crystal Display, igama elibanzi lobuchwepheshe bokuboniswa kwedijithali. Amakristalu oketshezi ngokwawo awakhiphi ukukhanya futhi adinga isibani sangemuva ukuze siwakhanyisele, njengebhokisi lokukhanya lokukhangisa.

Kalula nje, izikrini ze-LCD ne-LED zisebenzisa ubuchwepheshe bokubonisa obubili. Izikrini ze-LCD zakhiwe ngamakristalu awuketshezi, kuyilapho izikrini ze-LED zakhiwe ngama-diode akhipha ukukhanya.

2. Umehluko Phakathi kwe-LED ne-LCD Display

Umehluko 1: Indlela Yokusebenza

Ama-LED angama-semiconductor light-emitting diode. Ubuhlalu be-LED benziwe buncane bufinyelele ezingeni le-micron, ngobuhlalu obuncane be-LED obufana nobunye busebenza njengephikseli. Iphaneli yesikrini yakhiwe ngokuqondile lobu buhlalu be-LED bezinga le-micron. Ngakolunye uhlangothi, isikrini se-LCD empeleni siyisibonisi sekristalu esiwuketshezi. Umgomo wayo oyinhloko wokusebenza uhilela ukuvuselela ama-molecule e-crystal ewuketshezi anamanje kagesi ukuze akhiqize amachashazi, imigqa, nezindawo, ngokuhambisana ne-backlight, ukwakha isithombe.

Umehluko 2: Ukukhanya

Isivinini sokuphendula sesici sokubonisa se-LED esisodwa sishesha izikhathi ezingu-1,000 kune-LCD. Lokhu kunikeza izibonisi ze-LED inzuzo enkulu ekukhanyeni, okuzenza zibonakale ngokucacile ngisho nasekukhanyeni okukhanyayo. Nokho, ukukhanya okuphezulu akusiyo inzuzo ngaso sonke isikhathi; kuyilapho ukukhanya okuphakeme kungcono ekubukeni ukude, kungaba sobala kakhulu uma ubuka eduze. Izikrini ze-LCD zikhipha ukukhanya ngokukhanya kwe-refract, okwenza ukukhanya kube lula futhi kunciphise kancane emehlweni, kodwa kube nzima ukubuka ekukhanyeni okukhanyayo. Ngakho-ke, ezibukweni ezikude, izikrini ze-LED zifaneleka kakhulu, kuyilapho izikrini ze-LCD zingcono ekubukeni eduze.

Umehluko 3: Isibonisi sombala

Mayelana nekhwalithi yombala, izikrini ze-LCD zinokusebenza kombala okungcono kanye nekhwalithi yesithombe ecebile, ecace kakhulu, ikakhulukazi ekunikezelweni kwe-grayscale.

Umehluko 4: Ukusetshenziswa kwamandla

Isilinganiso sokusetshenziswa kwamandla kwe-LED kuya ku-LCD cishe singu-1:10. Lokhu kungenxa yokuthi ama-LCDs avula noma avale yonke isendlalelo se-backlight; ngokuphambene, ama-LED angakhanyisa amaphikseli athile kuphela esikrinini, okuwenza awonge kakhulu amandla.

Umehluko 5: Qhathanisa

Ngenxa yemvelo yokuzikhanyisa yama-LED, ahlinzeka ngokuhlukile okungcono uma kuqhathaniswa nama-LCD. Ukuba khona kwe-backlight kuma-LCD kwenza kube nzima ukuzuza abamnyama bangempela.

Umehluko 6: Izilinganiso zokuvuselela

Izinga lokuvuselela isikrini se-LED liphezulu ngoba siphendula ngokushesha futhi sidlala ividiyo ngokushelela, kuyilapho isikrini se-LCD singadonsa ngenxa yokunensa kokuphendula.

Umehluko 7: Ama-engeli wokubuka

Isikrini se-LED sine-angle yokubuka ebanzi, ngoba umthombo wokukhanya ufana kakhulu, kungakhathaliseki ukuthi iyiphi i-engeli, ikhwalithi yesithombe inhle kakhulu, isikrini se-LCD nge-engeli enkulu, ikhwalithi yesithombe izowohloka.

Umehluko 8: Ubude bempilo

Impilo yesikrini se-LED yinde, ngenxa yokuthi ama-diode alo akhipha ukukhanya aqinile futhi akulula ukuguga, kuyilapho isistimu yokukhanyisa isikrini se-LCD nezinto zekristalu eyi-liquid zizowohloka kancane kancane ngokuhamba kwesikhathi.

3. Yikuphi Okungcono, i-LED noma i-LCD?

Ama-LCD asebenzisa izinto ezingaphili, eziguga kancane futhi eziphila isikhathi eside. Ama-LED, ngakolunye uhlangothi, asebenzisa izinto eziphilayo, ngakho-ke ubude bawo bokuphila bufushane kunezikrini ze-LCD.

Ngakho-ke, izikrini ze-LCD, ezakhiwe ngamakristalu awuketshezi, ziphila isikhathi eside kodwa zisebenzisa amandla engeziwe ngenxa yokukhanya kwangemuva okuvuliwe konke/kokucisha konke. Izikrini ze-LED, ezakhiwe ngama-diode akhipha ukukhanya, zinesikhathi esifushane sokuphila, kodwa i-pixel ngayinye ingumthombo wokukhanya, enciphisa ukusetshenziswa kwamandla ngesikhathi sokusetshenziswa.
