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 ngokulandelana futhi alayishwe kokuqukethwe kulo mugqa, ashayele yonke imigqa yamaphikseli ukuze aveze isithombe esiphelele.
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 uma ebonisa izithombe ezimnyama zonke, 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 ekwendlaleni nasekusebenzeni okuguquguqukayo ngokuthuthukiswa kobuchwepheshe bokubonisa okuholela, ngaphezu kwalokho, ukujula kwesikrini se-LED kulungile ngokwanele ikakhulukaziI-YONWAYTECH isixazululo sokubonisa sephikseli emincane yephikseli.
