Ngaba uyazi ukuba yintoni umahluko phakathi kwe-LCD, i-LED kunye ne-OLED?
Isikrini sokubonisa sibizwa ngokuba sesinye sezona zinto ziqanjiweyo zenkulungwane yama-20.
Ayininzi kakhulu. Ubomi bethu bunobuqaqawuli ngenxa yenkangeleko yabo.
Ngophuhliso lwenzululwazi kunye neteknoloji, izikrini zokubonisa azisekho kuphela ekusebenziseni izikrini zeTV.
Ubungakanani obukhulu bentengisoI-LED ibonisa izikriniqalisa ukungena ebomini bethu, njengeendawo zokuthenga, ii-cinema, kunokubonwa kwiindawo ezahlukeneyo ezifana neendawo zemidlalo yangaphakathi, kwaye ngeli xesha, i-LCD, i-LED, i-OLED kunye namanye amagama aqeqeshiweyo ahlala ezindlebeni zethu, nangona amaninzi. abantu bathetha ngazo, kodwa abantu abaninzi banolwazi oluncinane ngazo.
Ke, yintoni umahluko phakathi kwe-Lcd, i-led kunye ne-oled?
LCD,IZIMBONISO ze-LEDKwaye OLED
1, LCD
I-LCD imfutshane kwiLiquid Crystal Display ngesiNgesi.
Kukho ubukhulu becala TFT, UFB, TFD, STN kunye nezinye iintlobo. Ubume bayo bubandakanya ibhola yeplastiki, ibhola yeglasi, iglue yesakhelo, i-glass substrate, i-polarizer ephezulu, i-directional layer, i-crystal ye-liquid, iphethini ye-ITO eqhubayo, i-conduction point, i-IPO electrode kunye ne-polarizer ephantsi.
Ukuthatha isikrini sentengiso ye-LCD njengomzekelo, yamkela eyona TFT-LCD eyaziwayo, eyifilimu ebhityileyo ye-transistor liquid crystal display. Ubume bayo obusisiseko kukubeka ibhokisi yekristale elulwelo kwiinxalenye ezimbini zeglasi ezihambelanayo, usete ifilimu ecekethekileyo ye-transistor (eyi-TFT) kwiglasi esezantsi ye-substrate, usete isihluzo sombala kwiglasi esezantsi yeglasi, isalathiso sokujikeleza kweemolekyuli zekristale zamanzi zilawulwa ngumqondiso. kunye nokutshintsha kwamandla ombane kwi-transistor yefilim ebhityileyo, ukuze kuphunyezwe injongo yokubonisa ngokulawula ukuba ukukhanya kwepikseli nganye kukhutshwa okanye hayi.
Umgaqo wokuboniswa kwekristale yolwelo kukuba ikristale yolwelo iya kubonisa iimpawu ezahlukeneyo zokukhanya phantsi kwesenzo sombane ohlukeneyo. Isikrini sokubonisa ikristale yolwelo yenziwe ngamalungu amaninzi ekristale engamanzi. Kwisikrini sokubonisa ikristale elulwelo lwemonochrome, ikristale elulwelo yipixel (eyona yunithi incinci inokuboniswa kwiscreen sekhompyuter), kwiscreen sombala wekristale yolwelo, ipixel nganye ineekristale zolwelo ezibomvu, eziluhlaza kunye naluhlaza. Ngexesha elifanayo, kunokuqwalaselwa ukuba kukho irejista ye-8-bit emva kwekristale nganye yolwelo, kwaye ixabiso lerejista limisela ukukhanya kweeyunithi ezintathu zekristale zamanzi, nangona kunjalo, ixabiso lerejista alikho ngokuthe ngqo. qhuba ukuqaqamba kweeyunithi ezintathu zekristale zolwelo, kodwa zifikelelwa nge “palette. Akukho ngqiqweni ukuxhobisa ipixel nganye ngerejista ebonakalayo. Enyanisweni, umgca omnye kuphela weerejista uxhotyiswe. Ezi rejista ziqhagamshelwe kumgca ngamnye weepikseli ngokujika kwaye zilayishwe kwimixholo yalo mgca, qhuba yonke imigca yepixel ukubonisa umfanekiso opheleleyo.
I-LED imfutshane kwi-Light Emitting Diode. Luhlobo lwe-semiconductor diode, enokuguqula amandla ombane abe ngamandla okukhanya.
Xa ii-electron zidityaniswe nemingxuma, ukukhanya okubonakalayo kunokukhutshwa, ngoko kusenokusetyenziswa ukwenza ii-diode ezikhupha ukukhanya. Njenge-diodes eqhelekileyo, ii-diode ezikhupha ukukhanya zenziwe nge-pn junction kwaye zine-conductivity ye-unidirectional.
Umgaqo wayo xa i-voltage echanekileyo yongezwa kwi-diode ekhupha ukukhanya, imingxuma efakwe kwindawo ye-N ukusuka kwindawo ye-P kunye nee-electron ezifakwe kwindawo ye-P ukusuka kwindawo ye-N, ngaphakathi kwee-microns ezimbalwa kufuphi ne-PN junction, ixutywe. ngee-electron ezikummandla we-N kunye nemingxunya ekummandla we-P ngokulandelelanayo ukuvelisa i-fluorescence ephumayo ezenzekelayo.
Amandla ee-electron kunye nemingxuma kwizinto ezahlukeneyo ze-semiconductor zihlukile. Xa ii-electron kunye nemingxuma zixutywe, umthamo wamandla okhutshiweyo uyahluka. Okukhona amandla akhutshwayo, kokukhona bufutshane ubude bokukhanya okukhutshiweyo. Ngokuqhelekileyo zisetyenziselwa iidiode ezikhupha ukukhanya okubomvu, ukukhanya okuluhlaza okanye ukukhanya okuphuzi.
I-LED ibizwa ngokuba nguMthombo wokuKhanya wesizukulwana sesine, oneempawu zokonga amandla, ukhuseleko lokusingqongileyo, ukhuseleko, ubomi benkonzo ende, ukusetyenziswa kwamandla aphantsi, ubushushu obuphantsi, ukukhanya okuphezulu, ukungangeni kwamanzi, okuncinci, ukothuka, ukuncipha lula, ukukhanya okugxininisiweyo, ukugcinwa okulula. , njalo njalo, inokusetyenziswa ngokubanzi kwiinkalo ezahlukeneyo ezifana nesalathiso,Umboniso we-LED, umhlobiso, ukukhanya kwe-backlight, ukukhanya ngokubanzi, njl.
Umzekelo, isikrini se-LED, iSkrini se-Advertising ye-LED, isibane somqondiso wethrafikhi, isibane semoto, ukukhanya kwe-LCD, ukukhanya kwendlu kunye neminye imithombo yokukhanyisa.
3, OLED
I-OLED imfutshane ye-Organic Light-Emitting Diode. Ikwaziwa ngokuba yi-organic electric laser display, i-organic light emit semiconductor.
Le diode yafunyanwa kwibhubhoratri ngo-1979 nguprofesa waseTshayina waseMelika uDeng Qingyun.
I-OLED iqulethe iyunithi yokubonisa ye-OLED yangaphandle kunye nezinto ezikhupha ukukhanya ezifakwe kuyo, kuquka i-cathode, i-emission layer, i-conductive layer, i-anode kunye nesiseko. Iyunithi nganye yokubonisa i-OLED inokulawula ukuvelisa ukukhanya kwemibala emithathu eyahlukeneyo.
Itekhnoloji yokubonisa i-OLED inophawu lokuzikhanyisa, isebenzisa i-organic material coating kunye ne-substrate yeglasi. Xa kukho ukujikeleza kombane, ezi zixhobo eziphilayo ziya kukhupha ukukhanya, kwaye i-angle ebonakalayo ye-OLED isikrini sokubonisa inkulu, kwaye inokugcina ukusetyenziswa kwamandla. Ukususela ngo-2003, le teknoloji yokubonisa isetyenziswe kubadlali bomculo weMP3.
Kule mihla, ummeli obalaseleyo wesicelo se-OLED sisikrini sefowuni ephathwayo. Isikrini se-OLED sinokubonisa umahluko ogqibeleleyo wemifanekiso, kwaye umfanekiso wokubonisa uya kucaca ngakumbi kwaye ube yinyani. Ngenxa yeempawu zekristale yolwelo, isikrini se-LCD asixhasi ukugoba. Ngokwahlukileyo, i-OLED inokwenziwa isikrini esigobileyo.
Umahluko Phakathi KweziThathu
1, Kwi-gamut yombala
Isikrini se-OLED sinokubonisa imibala engapheliyo kwaye asichatshazelwa zizibane zangasemva, kodwa isikrini se-LED esinokukhanya okungcono kunye ne-angle yokujonga.
Iipixels zineenzuzo ezinkulu xa ubonisa yonke imifanekiso emnyama, okwangoku, umbala we-gamut wesikrini se-LCD uphakathi kwe-72 kunye ne-92 yeepesenti, ngelixa i-led screen ingaphezulu kwe-118 ekhulwini.
2, Ngokwexabiso
Izikrini ze-LED ezinobukhulu obufanayo zixabisa ngaphezu kwephindwe kabini njengee-LCD kwi-pixel encinci ye-pitch led video wall, ngelixa izikrini ze-OLED zibiza kakhulu.
I-3, Ngokubhekiselele kwitekhnoloji evuthiweyo yokukhanya kunye nokungenamthungo.
Isikrini se-LED singcono kakhulu kunesikrini se-LCD kunye ne-OLED ngokuqaqamba kunye nokungenamthungo, ngakumbi kudonga olukhulu lwevidiyo olukhokelela kwiscreen sentengiso okanye ukusetyenziswa kweempawu zedijithali zangaphakathi.
Ngelixa i-LCD okanye i-OLED yobungakanani obukhulu bodonga lwevidiyo yedijithali efuna ukucandwa, umsantsa phakathi kweepaneli uya kuba nefuthe ekusebenzeni kunye nokuziva kombukeli.
I-4, Ngokubhekiselele ekusebenzeni kwevidiyo kunye ne-angle yesiboniso
Ukubonakaliswa okuthe ngqo kukuba i-angle ebonakalayo yesikrini se-LCD incinci kakhulu, ngelixa isikrini se-LED sanelisayo ekubekweni kunye nokusebenza okuguquguqukayo kunye nophuhliso lwetekhnoloji yomboniso okhokelwayo, ukongeza, ubunzulu besikrini se-LED bulunge ngokwaneleyo ngakumbiYONWAYTECH iphikseli emxinwa yephikseli ekhokelela kwisisombululo somboniso.
