I. isimiso sokuqamba se-LCD
I-crystal ewuketshezi
Isikrini sibukeka njengesikrini esisodwa kuphela, empeleni, sakhiwe izingcezu ezine ezinkulu (isihlungi, i-polarizer, ingilazi, isibani esibandayo se-cathode fluorescent), lapha ukuze sikunikeze incazelo emfushane.
Isihlungi: isizathu sokuthi kungani iphaneli ye-TFT LCD ingakhiqiza ukuguqulwa kombala ikakhulukazi isihlungi sombala.Iphaneli ebizwa ngokuthi i-liquid crystal panel ingenza ama-molecule ekristalu ewuketshezi ame emgqeni ngokushintsha kwamandla kagesi okushayela i-IC, ukuze kuboniswe isithombe.Isithombe ngokwaso simnyama nokumhlophe, futhi singashintshwa sibe iphethini yombala ngesihlungi.
Ipuleti le-polarizing: ipuleti le-polarizing lingaguqula ukukhanya kwemvelo kube izakhi ezihlukanisayo eziqondile, ukusebenza kwazo ukuhlukanisa ukukhanya komugqa okungenayo okunezingxenye ze-polarizing, ingxenye eyodwa ukwenza kudlule, enye ingxenye ukumuncwa, ukubonakaliswa, ukuhlakazeka neminye imiphumela ukuyenza. kufihliwe, nciphisa isizukulwane samaphuzu agqamile/amabi.
Isibani se-cold cathode fluorescent: sibonakala ngevolumu encane, ukukhanya okuphezulu nokuphila isikhathi eside.Yenziwe ngengilazi eklanywe ngokukhethekile futhi ecutshunguliwe, izibani ezibandayo ze-cathode fluorescent zingasetshenziswa ngokuphindaphindiwe ngemva kokukhanyisa okusheshayo futhi zingakwazi ukumelana nokusebenza kokushintsha okungafika ku-30,000.Ngenxa yokuthi i-cathode fluorescent ebandayo isibani SISEBENZISA impushana ye-phosphor enemibala emithathu, ngakho amandla ayo akhanyayo ayanda, ukuncipha kokukhanya kuyancipha, ukusebenza kokushisa kombala kuhle, ngaleyo ndlela kukhiqiza inani lokushisa liphansi kakhulu, livikela ngempumelelo isibonisi sethu sekristalu ewuketshezi impilo.
Izimbangela kanye nokuvinjelwa kwamachashazi akhanyayo/amabi ekristalu ewuketshezi
1. Izizathu zomkhiqizi:
Indawo ekhanyayo/embi yaziwa nangokuthi indawo ekhanyayo ye-LCD, okuwuhlobo lomonakalo obonakalayo we-LCD.Ibangelwa ikakhulukazi ukucindezelwa kwamandla angaphandle noma ukuwohloka okuncane kwepuleti lokubonisa langaphakathi lendawo ekhanyayo.
Iphikseli ngayinye esikrinini se-LCD inemibala emithathu eyinhloko, ebomvu, eluhlaza okwesibhakabhaka, eluhlaza okwesibhakabhaka, ehlanganisa ukukhiqiza imibala ehlukahlukene.Thatha i-LCD engu-15-intshi njengesibonelo, indawo yesikrini se-LCD yayo ingu-304.1mm*228.1mm, ukulungiswa kungu-1024* 768, futhi iphikseli ngayinye ye-LCD yakhiwe ngeyunithi yombala eyinhloko ye-RGB. Amaphikseli ekristalu ewuketshezi “angamabhokisi ekristalu ewuketshezi” akhiwe ngokuthela ikristalu ewuketshezi esikhunjeni esingaguquki.Inombolo yanjalo "amabhokisi ekristalu ewuketshezi" kusibonisi se-LCD esingu-15 intshi ngu-1024*768*3 = 2.35 million!Bungakanani usayizi webhokisi le-LCD?Singakwazi ukubala kalula: ubude = 0.297mm, ububanzi = 0.297/3 = 0.099mm!Ngamanye amazwi, izigidi ezingu-2.35 “amabhokisi ekristalu ewuketshezi” anendawo engu-0.297mm*0.099mm kuphela ahlelwe ngokuminyene ngaphansi kwendawo engu-304.1mm*228.1mm, kanye neshubhu lokushayela elishayela ibhokisi lekristalu eliwuketshezi lihlanganisiwe. ngemuva kwebhokisi le-crystal liquid.Ngokusobala, izidingo zenqubo yokukhiqiza yomugqa wokukhiqiza ziphakeme kakhulu, kubuchwepheshe bamanje kanye nobuciko, futhi azikwazi ukuqinisekisa ukuthi i-batch ngayinye ekhiqizwa isikrini se-LCD ayiyona amaphuzu akhanyayo / amabi, abakhiqizi ngokuvamile bagwema amaphuzu akhanyayo / amabi ingxenye yephaneli ye-LCD, awekho amaphuzu agqamile/amabi noma izindawo ezikhanyayo ezimbalwa kakhulu/iphaneli ye-LCD embi yabakhiqizi abanamandla, futhi ukukhanya/amaphoyinti amabi ngaphezulu kwesikrini se-LCD ngokuvamile sinikeza abakhiqizi abancane abancane ekukhiqizeni i-LCD eshibhile.
Ngobuchwepheshe, indawo ekhanyayo/embi i-pixel engenakulungiseka kuphaneli ye-LCD ekhiqizwa ngesikhathi sokukhiqiza.Iphaneli ye-LCD yakhiwe ngamaphikseli ekristalu ewuketshezi angaguquki, ngalinye linama-transistors amathathu ahambisana nezihlungi ezibomvu, eziluhlaza kanye neziluhlaza okwesibhakabhaka ngemuva kwe 0.099mm liquid crystal pixel
I-transistor engalungile noma i-short circuit yenza le pixel ibe iphuzu elikhanyayo/elibi.Ngaphezu kwalokho, iphikseli ye-LCD ngayinye iphinde ihlanganiswe ngemuva kweshubhu lomshayeli elihlukile ukuze iyishayele. ayikwazi ngokuvamile ukushintsha umbala futhi izoba iphoyinti lombala elingashintshi, elizobonakala ngokucacile kweminye imibala engemuva.Leli iphuzu elikhanyayo/elibi le-LCD.Ibala elikhanyayo/elibi wuhlobo lokulimala komzimba okungenakugwenywa ngo-100% ekukhiqizweni nasekusetshenzisweni kwesikrini se-LCD.Ezimweni eziningi, ikhiqizwa ekukhiqizweni kwesikrini.Inqobo nje uma umbala owodwa noma eminingi eyinhloko eyakha iphikseli eyodwa yonakalisiwe, kukhiqizwa izindawo ezikhanyayo/ezimbi, futhi ukukhiqizwa nokusetshenziswa kungase kubangele umonakalo.
Ngokomhlangano wamazwe ngamazwe, i-liquid crystal display inamaphoyinti angu-3 angaphansi agqamile/amabi kububanzi obuvunyelwe, nokho-ke umthengi mancane amathuba okuthi azimisele ukuthenga imonitha enephuzu elikhanyayo/elibi lapho ethenga ikristalu ewuketshezi, ngakho-ke umenzi wekristalu ewuketshezi. enephuzu elikhanyayo/elibi ngokuvamile lithengisa kanzima kakhulu.Ingabe abakhiqizi bamaphaneli babhekana kanjani namabala amathathu noma ngaphezulu agqamile/amabi ngenxa yenqubo yokukhiqiza?Ukuze bathole inzuzo, abanye abakhiqizi ngeke bazibhubhise lezi zikrini ze-LCD, futhi ezimweni eziningi, izosebenzisa okokusebenza okuchwepheshile ukwelapha izindawo ezimbi/ezimbi, ukuze kuzuzwe umphumela wokungabi bikho kwamachashaza amabi/amabi ebusweni emehlweni. yokukhiqiza, ukuze kuzuzwe inhloso yokunciphisa izindleko.Lolu hlobo lomkhiqizo lunenzuzo enanini, kodwa luzokhiqiza izindawo ezikhanyayo/ezimbi ngemva kokusetshenziswa.Okwamanje emakethe imibukiso eminingi eshibhile yekristalu ewuketshezi injalo.kucutshunguliwe, ngakho-ke awufuni ukuthenga i-liquid display display eshibhile, ukuthenga amabhrendi angaziwa. Ngiyajabula ukuthenga isibonisi esingagqami - esingabizi kakhulu.Ngoba ngemva kwesikhashana, izinto ongafuni ukuzibona zingase zigcine ukwenzeka.
2. Izizathu zokusetshenziswa
Amanye amaphuzu e-LCD akhanyayo/amabi angase abangwe ukusetshenziswa kwenqubo, vele akutshele mayelana nokusetshenziswa okuvamile kwezinye izinyathelo zokuphepha:
(1) ungafaki amasistimu amaningi ngesikhathi esisodwa;Ukufakwa kwamasistimu amaningi kwinqubo yokushintsha kuzodala izinga elithile lomonakalo ku-LCD.
(2) gcina i-voltage namandla evamile;
(3) ungathinti inkinobho ye-LCD nganoma yisiphi isikhathi.
Zonke lezi zici ezintathu zithinta ngokuqondile noma ngokungaqondile ukusebenza okuvamile kwama-molecule "e-liquid crystal box", okungase kuholele ekukhiqizeni amaphuzu akhanyayo / amabi.Eqinisweni, izindawo ezikhanyayo / ezimbi zabathengi ohlelweni lokusetshenziswa zingaqondwa. ngokuhlola onjiniyela.Ngisho nezindawo ezikhanyayo/ezimbi zabathengi zingaqondwa uma abakhiqizi bengalimazi abathengi ngaphandle konembeza.
Izinga likazwelonke ngu-335, okusho ukuthi izindawo ezintathu ezikhanyayo, noma amabala amathathu amnyama, afaneleka njengokujwayelekile.
