Sekuyisikhathi sokukhuluma ngesinye sezihloko ezizibuza kakhulu?Siyini lesi sihloko?Uyini umehluko phakathi kwezikrini ze-LED nezikrini ze-LCD?Ngaphambi kokubhekana nalolu daba, uma senza izincazelo zalobu buchwepheshe obubili sizoluqonda kangcono udaba.
Isikrini se-LED: Ubuchwepheshe obungandiswa noma buncishiswe ngokuhlanganiswa kwezibani ze-LED zekhwalithi ephezulu nokulawulwa kwama-chips kagesi.I-LCD: Amakristalu oketshezi ahlukaniswa ngogesi wesikrini.Umehluko omkhulu phakathi kwe-LED ne-LCD waziwa ngokuthi ubuchwepheshe bokukhanyisa.
I-LCD nama-TV e-LED uma kuqhathaniswa nama-TV amashubhu amadala;ubucwepheshe obubukeka obuncane nobusesitayeleni obunekhwalithi yesithombe ecace kakhulu.Ikhwalithi yesistimu yokukhanyisa ithinta ikhwalithi yesithombe.
Umehluko ohlukanisa izikrini ze-LED nezikrini ze-LCD!
Nakuba izikrini ze-LCD zisebenzisa izibani ze-fluorescent, ubuchwepheshe bokukhanyisa i-LED busebenzisa ikhwalithi yokukhanya futhi budlulisela isithombe ngokuphelele, ngenxa yalesi sizathu, izibonisi ze-LED zivame ukuba phakathi kwemikhiqizo ethandwayo.
Njengoba ama-diode akhipha ukukhanya kubuchwepheshe be-LED asuselwa ku-pixel, umbala omnyama ubonakala njengomnyama wangempela.Uma sibheka amanani okuqhathanisa, izofinyelela ezinkulungwaneni ezi-5 kuya ku-5 million.
Ezibonisini ze-LCD, ikhwalithi yemibala ilingana nekhwalithi yekristalu yephaneli.
Ukusetshenziswa kwamandla kubaluleke kakhulu kithi sonke.
Lapho sisebenzisa amandla amancane ekhaya, emsebenzini nangaphandle, kulapho kuzuza khona wonke umuntu.
Izikrini ze-LED zisebenzisa amandla angaphansi kwama-40% kunezikrini ze-LCD.Uma ucabangela unyaka wonke, wonga amandla amaningi.
Ezikrinini ze-LED, iseli eliletha isithombe esincane kunazo zonke libizwa ngokuthi i-pixel.Isithombe esiyinhloko sakhiwe ngokuhlanganiswa kwamaphikseli.Isakhiwo esincane kunazo zonke esakhiwe ngokuhlangana kwamaphikseli sibizwa ngokuthi i-matrix.Ngokuhlanganisa amamojula efomini le-matrix, ikhabhinethi eyenza isikrini iyakhiwa.Yini engaphakathi endlini?Uma sihlola ingaphakathi lendlwana;Imojula iqukethe iyunithi yamandla, ifeni, izintambo ezixhumayo, inqola eyamukelayo nekhadi lokuthumela.Ukukhiqizwa kweKhabhinethi kufanele kwenziwe ngochwepheshe abawazi kahle umsebenzi futhi abangochwepheshe.
I-LCD TV ikhanyiswa nge-fluorescence futhi uhlelo lokukhanyisa luhlinzekwa emaphethelweni esikrini, ama-TV e-LED akhanyiswa izibani ze-LED, ukukhanya kwenziwa ngemuva kwesikrini, futhi ikhwalithi yesithombe inkulu kuma-TV we-LED.
Ngokuya ngoshintsho ekubukeni kwakho, amathelevishini e-LCD angabangela ukwehla nokwenyuka kwekhwalithi yesithombe.Uma usukuma ubuka i-LCD, utshekisa noma ubheka phansi esikrinini, ubona isithombe simnyama.Kungase kube khona umehluko omncane lapho ushintsha umbono wakho kuma-TV we-LED, kodwa ngokuvamile alukho ushintsho kukhwalithi yesithombe.Isizathu sihlobene ngokuphelele nesistimu yokukhanyisa kanye nekhwalithi yesistimu yokukhanya eyisebenzisayo.
Ama-TV e-LED anikeza imibala egcwele kakhulu ngenxa yobuchwepheshe obusetshenzisiwe, futhi ayakwazi ukusebenzisa ugesi omncane.Izikrini ze-LED zivame ukusetshenziswa esimweni sezulu sangaphandle, ezindaweni zokusebenza, izindawo zokuzivocavoca, izinkundla kanye nokukhangisa kwangaphandle.Ngaphezu kwalokho, ingafakwa kubukhulu obufunwayo nobude.Uma ufuna ukusizakala ngobuchwepheshe be-LED, kufanele usebenze nezinkampani ezinezinkomba ezinhle.
