Uyazi ukuthi yini umehluko we-LCD, i-LED ne-OLED?

Isikrini esibonisiwe sibizwa ngokunye kokusungulwa okukhulu kwekhulu lama-20.

Akuningi kakhulu.Ukuphila kwethu kuyakhazimula ngenxa yokubukeka kwayo.

Ngokuthuthuka kwesayensi nobuchwepheshe, izikrini zokubonisa azisakhawulelwe ekusetshenzisweni kwezikrini ze-TV.

Izentengiso ezinosayizi omkhuluI-LED ibonisa izikrinisiqale ukungena ezimpilweni zethu, njengezitolo ezinkulu, ama-cinema, kungabonakala ezindaweni ezahlukahlukene njengezindawo zemidlalo zasendlini, futhi ngalesi sikhathi, i-LCD, i-LED, i-OLED namanye amagama ochwepheshe nawo ahlala ezindlebeni zethu, nakuba abaningi. abantu bakhuluma ngazo, kodwa abantu abaningi bazi okuncane ngazo.

Ngakho-ke, uyini umehluko phakathi kwe-Lcd, i-led ne-oled?

LCD,IZIKHOMBISO ze-LEDFuthi OLED

1, LCD

I-LCD imfushane nge-Liquid Crystal Display ngesiNgisi.

Kukhona ikakhulukazi i-TFT, UFB, TFD, STN nezinye izinhlobo.Isakhiwo sawo sihlanganisa ibhola lepulasitiki, ibhola lengilazi, i-glue yohlaka, i-glass substrate, i-polarizer engenhla, ungqimba oluqondisayo, i-crystal ewuketshezi, iphethini ye-ITO eqhubayo, iphoyinti lokuqhuba, i-IPO electrode kanye ne-polarizer ephansi.

Uma sithatha isikrini sokukhangisa se-LCD njengesibonelo, samukela i-TFT-LCD eyaziwa kakhulu, okuwukubonisa kwekristalu okuwuketshezi lwefilimu elincanyana.Isakhiwo salo esiyisisekelo ukubeka ibhokisi lekristalu eliwuketshezi kuma-substrates amabili engilazi afanayo, usethe i-transistor yefilimu encane (okungukuthi i-TFT) engilazini engezansi ye-substrate, usethe isihlungi sombala engilazini engenhla ye-substrate, isiqondiso sokujikeleza kwama-molecule e-crystal ewuketshezi kulawulwa isignali. kanye nokushintsha kwamandla kagesi ku-transistor yefilimu ezacile, ukuze kufezwe injongo yesibonisi ngokulawula ukuthi ukukhanya okumhlophe kwephikseli ngayinye kukhishwa noma cha.

Umgomo wokuboniswa kwekristalu eliwuketshezi ukuthi i-liquid crystal izokwethula izici zokukhanya ezihlukile ngaphansi kwesenzo sama-voltages ahlukene.Isikrini sokubonisa i-liquid crystal sakhiwe ngamaqoqo amaningi e-liquid crystal.Esikrinini se-monochrome liquid crystal display, i-liquid crystal iyiphikiseli (iyunithi encane kakhulu engaboniswa esikrinini sekhompyutha), esikrinini sokubonisa ikristalu eliwuketshezi, iphikseli ngalinye liqukethe amakristalu aketshezi abomvu, aluhlaza okwesibhakabhaka.Ngesikhathi esifanayo, kungacatshangwa ukuthi kukhona irejista ye-8-bit ngemuva kwe-crystal ngayinye ye-liquid, futhi inani lerejista linquma ukukhanya kweyunithi ngayinye ye-crystal liquid, noma kunjalo, inani lerejista alikho ngokuqondile. ishayela ukukhanya kwamayunithi amathathu ekristalu ewuketshezi, kodwa ifinyelelwa “ngephalethi.Akunangqondo ukuhlomisa i-pixel ngayinye ngerejista ebonakalayo.Eqinisweni, kufakwe umugqa owodwa kuphela wamarejista.Lawa marejista axhunywe kulayini wamaphikseli ngamunye ngokushintshana futhi alayishwe kokuqukethwe kulo mugqa, ashayele yonke imigqa yamaphikseli ukuze aveze isithombe esiphelele.

2, IZIkrini ze-LED

I-LED imfushane nge-Light Emitting Diode.Iwuhlobo lwe-semiconductor diode, engaguqula amandla kagesi abe amandla okukhanya.

Lapho ama-electron ehlanganiswa nezimbobo, ukukhanya okubonakalayo kungasakazwa, ngakho kungasetshenziswa ukwenza ama-diode akhipha ukukhanya.Njengama-diode avamile, ama-diode akhipha ukukhanya akhiwe ngokuhlangana kwe-pn futhi abe nokuqhutshwa kwe-unidirectional.

Umgomo wayo lapho i-voltage ephozithivu yengezwa ku-diode ekhipha ukukhanya, izimbobo ezijovelwe endaweni engu-N ukusuka endaweni ye-P kanye nama-electron afakwe endaweni ye-P esuka endaweni engu-N, ngaphakathi kwama-microns ambalwa eduze nendawo ye-PN, ihlanganiswe. nama-electron esifundeni esingu-N nezimbobo esifundeni esingu-P ngokulandelanayo ukuze kukhiqizwe ukukhishwa kwe-fluorescence ezenzakalelayo.

Izimo zamandla zama-electron nezimbobo ezintweni ezihlukene ze-semiconductor zihlukile.Lapho ama-electron nezimbobo kwakwakhe, inani lamandla akhishwe lihlukile.Lapho amandla engeziwe ekhishwa, iba mfushane ubude begagasi bokukhanya okukhishwayo.Okuvame ukusetshenziswa ama-diode akhipha ukukhanya okubomvu, ukukhanya okuluhlaza noma ukukhanya okuphuzi.

I-LED ibizwa nge-Fourth generation Light Source, enezici zokonga amandla, ukuvikelwa kwemvelo, ukuphepha, impilo ende yesevisi, ukusetshenziswa kwamandla okuphansi, ukushisa okuphansi, ukukhanya okuphezulu, ukungangeni kwamanzi, okuncane, ukushaqeka, ukufiphala okulula, i-concentrated light beam, ukulungiswa okulula. , njll, ingasetshenziswa kabanzi emikhakheni ehlukahlukene njengenkomba,Isibonisi se-LED, umhlobiso, ukukhanya kwangemuva, ukukhanya okuvamile, njll.

Isibonelo, isikrini sokubonisa se-LED, isikrini se-LED sokukhangisa, isilambu sethrafikhi, ilambu lemoto, ukukhanya kwe-LCD, ukukhanya kwasendlini neminye imithombo yokukhanyisa.

3, OLED

I-OLED imfushane nge-Organic Light-Emitting Diode.Eyaziwa nangokuthi i-organic electric laser display, i-organic light emitting semiconductor.

Le diode yatholwa elabhorethri ngo-1979 nguprofesa waseShayina waseMelika uDeng Qingyun.

I-OLED iqukethe iyunithi yokubonisa ye-OLED yangaphandle nezinto ezikhipha ukukhanya eziboshelwe kuyo, okuhlanganisa i-cathode, ungqimba olukhishwayo, ungqimba olubambayo, i-anode nesisekelo.Iyunithi ngayinye yokubonisa ye-OLED ingalawula ukukhiqiza ukukhanya kwemibala emithathu ehlukene.

Ubuchwepheshe bokubonisa i-OLED bunesici sokuzikhanyisa, kusetshenziswa i-organic material coating ne-glass substrate.Uma kukhona ukujikeleza kukagesi, lezi zinto eziphilayo zizokhipha ukukhanya, futhi i-engeli ebonakalayo yesikrini sokubonisa se-OLED inkulu, futhi ingonga ukusetshenziswa kwamandla.Kusukela ngo-2003, lobu buchwepheshe bokubonisa busetshenziswe kubadlali bomculo be-MP3.

Kulezi zinsuku, ummeleli ovelele wohlelo lwe-OLED yisikrini somakhalekhukhwini.Isikrini se-OLED singabonisa ukugqama okuhle kwesithombe, futhi isithombe esibonisiwe sizocaca kakhulu futhi sibe ngokoqobo.Ngenxa yezici zekristalu ewuketshezi, isikrini se-LCD asikusekeli ukugoba.Ngokuphambene, i-OLED ingenziwa ibe isikrini esigobile.

Umehluko Phakathi Kwabathathu

1, Ku-gamut yombala

Isikrini se-OLED singabonisa imibala engapheli futhi asithintwa amalambu angemuva, kodwa Isikrini se-LED esinokukhanya okungcono kanye ne-engeli yokubuka.

Amaphikseli anezinzuzo ezinhle lapho ebonisa izithombe ezimnyama, okwamanje, umbala we-gamut wesikrini se-LCD uphakathi kwamaphesenti angama-72 nangama-92, kuyilapho owesikrini esiholayo ungaphezulu kwamaphesenti ayi-118.

2, Ngokwentengo

Izikrini ze-LED ezinosayizi ofanayo zibiza ngaphezu kokuphindwe kabili kunezikrini ze-LCD odongeni lwevidiyo olunephikseli elincane le-pitch led, kuyilapho izikrini ze-OLED zibiza kakhulu.

3, Ngokuphathelene nobuchwepheshe obuvuthiwe bokukhanya nokungenamthungo.

Isikrini se-LED singcono kakhulu kunesikrini se-LCD kanye ne-OLED ngokugqama nangokungenamthungo, ikakhulukazi odongeni lwevidiyo enosayizi omkhulu wesikrini sokukhangisa noma ukusetshenziswa kwezimpawu zedijithali zasendlini.

Nakuba i-LCD noma i-OLED yodonga olukhulu lwevidiyo yedijithali edinga ukuhlukaniswa, igebe phakathi kwamaphaneli lizothinta ukusebenza nomuzwa wombukeli.

4, Mayelana nokusebenza kwevidiyo kanye ne-engeli yesibonisi

Ukubonakaliswa okuqondile ukuthi i-angle ebonakalayo yesikrini se-LCD incane kakhulu, kuyilapho isikrini se-LED siyenelisa ekubekweni nasekusebenzeni okuguquguqukayo ngokuthuthukiswa kobuchwepheshe bokubonisa okuholela, ngaphezu kwalokho, ukujula kwesikrini se-LED kulungile ngokwanele ikakhulukaziI-YONWAYTECH isixazululo sokubonisa sephikseli emincane yephikseli.
