I-LED vs LCD Isiboniso: Umahluko ongundoqo, izinto eziluncedo, kwaye yeyiphi eNgcono?

1. Yintoni i-LED, i-LCD?

I-LED imele i-Light-Emitting Diode, isixhobo se-semiconductor esenziwe kwiikhompawundi eziqulethe izinto ezifana ne-Gallium (Ga), i-Arsenic (As), i-Phosphorus (P), kunye ne-Nitrogen (N). Xa ii-electron ziphinda zidityaniswa nemingxuma, zikhupha ukukhanya okubonakalayo, nto leyo eyenza ii-LED zisebenze kakuhle ekuguquleni amandla ombane abe ngamandla okukhanya. Ii-LED zisetyenziswe ngokubanzi kwimiboniso kunye nokukhanyisa.

I-LCD, okanye iLiquid Crystal Display, ligama elibanzi letekhnoloji yokubonisa idijithali. Iikristale zolwelo ngokwazo azikhuphi kukhanya kwaye zifuna isibane esingasemva ukuze zikhanyise, kufana nebhokisi yokukhanya yentengiso.

Ukubeka ngokulula, izikrini ze-LCD kunye ne-LED zisebenzisa itekhnoloji yokubonisa ezimbini ezahlukeneyo. Izikrini ze-LCD zenziwe ngeekristale zolwelo, ngelixa izikrini ze-LED zenziwe ngeediode ezikhupha ukukhanya.

2. Umahluko phakathi kwe-LED kunye ne-LCD Display

Umahluko 1: Indlela yokuSebenza

Ii-LED zii-semiconductor light-emitting diode. Amaso e-LED enziwe amancinci ukuya kwinqanaba le-micron, kunye nentsimbi nganye encinci ye-LED esebenza njengepikseli. Iphaneli yesikrini iqulunqwe ngokuthe ngqo ngala maso e-LED akwinqanaba le-micron. Kwelinye icala, isikrini se-LCD ngokuyimfuneko sisiboniso sekristale engamanzi. Umgaqo wayo oyintloko wokusebenza ubandakanya ukuvuselela iimolekyuli zekristale zamanzi kunye nombane wangoku ukuvelisa amachaphaza, imigca, kunye neendawo eziphezulu, ngokubambisana ne-backlight, ukwenza umfanekiso.

Umahluko 2: Ukuqaqamba

Isantya sokuphendula sento enye yokubonisa i-LED ngamaxesha angama-1,000 ngokukhawuleza kune-LCD. Oku kunika i-LED ibonisa inzuzo ebalulekileyo ekukhanyeni, ibenza babonakale ngokucacileyo nakukukhanya okukhanyayo. Nangona kunjalo, ukukhanya okuphezulu akusoloko kuyinzuzo; ngelixa ukuqaqamba okuphezulu kubhetele xa kujongwe kude, kunokuqaqamba kakhulu xa kujongwe ngokusondeleyo. Izikrini ze-LCD zikhupha ukukhanya ngokukhanyela ukukhanya, zenza ukukhanya kube thambile kwaye kungabi nzima emehlweni, kodwa kunzima ukujonga ekukhanyeni okuqaqambileyo. Ngoko ke, kwimiboniso ekude, izikrini ze-LED zifanelekile ngakumbi, ngelixa izikrini ze-LCD zingcono ukubukela ngokusondeleyo.

Umahluko 3: Umboniso Wombala

Ngokumalunga nomgangatho wombala, izikrini ze-LCD zinombala ongcono kunye nobutyebi, umgangatho wemifanekiso ecacileyo, ngakumbi kwi-grayscale enikezelayo.

Umahluko 4: Ukusetyenziswa kwamandla

Umlinganiselo wokusetyenziswa kwamandla we-LED ukuya kwi-LCD malunga ne-1:10. Oku kungenxa yokuba ii-LCDs zivula okanye zicime umaleko wonke we-backlight; ngokuchaseneyo, ii-LED zinokukhanyisa iipikseli ezithile kuphela kwiscreen, zizenze zibe namandla ngakumbi.

Umahluko 5: Ukuchasana

Enkosi kubume obuzikhanyisayo bee-LEDs, zibonelela ngokuthelekisa ngcono xa kuthelekiswa neeLCDs. Ubukho be-backlight kwi-LCDs kwenza kube nzima ukufikelela kumnyama wokwenyani.

Umahluko 6: Amaxabiso okuhlaziya

Izinga lohlaziyo lwesikrini se-LED liphezulu kuba liphendula ngokukhawuleza kwaye lidlala ividiyo ngokutyibilikayo, ngelixa isikrini se-LCD sinokutsala ngenxa yokuphendula kancinci.

Umahluko 7: Ii-engile zokujonga

Isikrini se-LED sinombono obanzi wokujonga, kuba umthombo wokukhanya ufana ngakumbi, kungakhathaliseki ukuba yiyiphi i-angle, umgangatho womfanekiso ulungile kakhulu, isikrini se-LCD kwi-angle enkulu, umgangatho womfanekiso uya kuhla.

Umahluko 8: Ixesha lokuphila

Ubomi bescreen se-LED bubude, kuba iidiode zayo ezikhupha ukukhanya zomelele kwaye akulula ukuguga, ngelixa inkqubo yokukhanya kwesikrini se-LCD kunye nezinto zekristale ezinolwelo ziya kuthotywa ngokuthe ngcembe ngokuhamba kwexesha.

3. Yeyiphi eNgcono, iLED okanye iLCD?

I-LCDs zisebenzisa izinto ezingaphiliyo, eziguga ngokucothayo kwaye zibenobomi obude. Ii-LED, ngakolunye uhlangothi, zisebenzisa izinto eziphilayo, ngoko ke ubomi babo bufutshane kunezikrini ze-LCD.

Ke ngoko, izikrini zeLCD, ezenziwe ngeekristale zolwelo, zinobomi obude kodwa zisebenzisa amandla amaninzi ngenxa yokukhanya kwe-backlight yonke / yonke into. Izikrini ze-LED, ezenziwe ngee-diode ezikhupha ukukhanya, zinobomi obufutshane, kodwa ipikseli nganye ngumthombo wokukhanya, ukunciphisa ukusetyenziswa kwamandla ngexesha lokusetyenziswa.

Ukuba ufuna ukufunda ngokunzulu ulwazi lweshishini le-LED,qhagamshelana nathi ngokuukufumana ngaphezulu
