Marka hore, filter alxanka isticmaalaya crystal dareere ahiftiinwaalka waxaa loo yaqaan Shaandheynta alxanka LCD, oo loo yaqaan ADF;Nidaamkeeda shaqadu waa: calaamadda arc marka la iibinayo qaansada waxaa loo beddelaa calaamadda micro-ampere ee hadda jirta ee tuubbada nuugista sawir-qaadista, oo laga beddelay iska-caabiyaha muunadda oo loo beddelo signalka korantada, oo ay weheliso awood, waxay ka saartaa qaybta DC ee qaansada, iyo ka dib waxay ku kordhisaa signalka danabka iyada oo loo marayo wareegga cod-weyneeye hawlgalka, signalka la kordhiyeyna waxa doorta laba-shabakad T, oo loo diro wareegga kontoroolka wareegga wareegga filter-hoose si uu u soo saaro amarka wadista wareegga darawalka LCD.Wareegga wadista LCD wuxuu ka beddelaa waalka iftiinka ka soo baxa iftiinka wuxuuna u beddelaa xaalad mugdi ah, si looga fogaado waxyeellada iftiinka arc ee isha alxanka.Korontada ilaa 48V waxay ka dhigaysa dareeraha crystal isla markiiba madow, ka dibna damiya danab sare muddo aad u gaaban gudahood, si looga fogaado danab sare in si joogto ah loo marsado crystal dareere ah, waxyeelo u gaar ah chip crystal dareere ah, iyo koronto isticmaalka.Qulqulka DC-ga ee dareeraha dareeraha wadista dareeraha, kaas oo soosaarkiisu la siman yahay wareegga shaqada, wuxuu u kaxeeyaa waalka iftiinka crystal-ka dareeraha ah inuu shaqeeyo.
Marka labaad, qaab dhismeedka iyo mabda'a shaqada ee crystal dareere ah.Crystal dareere ah ayaa ka duwan kan caadiga ah adag, dareere iyo xaaladda gaseous ee gobolka, waa in heerkul gaar ah labada dareere iyo crystal labada sifo ee xaaladda maaddada, oo joogto ah. Habaynta molecular ee xeryahooda organic, sida caadiga ah loo isticmaalo crystal dareere ah wajiga of crystal dareere ah, heerka kelli waa usha dheer dheer, dhererka ku saabsan 1 ~ 10nm, hoos ficil ee hadda kala duwan, molecules crystal dareere samayn doona wareeg joogto ah 90o habayn, taasoo keentay kala duwanaansho xagga gudbinta ah, si ay korontadu u shiddo oo ay u damiso marka ay kala duwan yihiin iftiinka iyo mugdiga.Karistaanka dareeraha ah ee ADF waa habka wadista oo si toos ah ugu dabaqa korantada wadista heerka pixel, si bandhiga dareeraha ah ee dareeraha ah uu si toos ah ugu dhigmo calaamadda danabka codsatay.Fikradda aasaasiga ah ee danabka la dabaqay ayaa ah in si joogto ah loo isticmaalo beer koronto oo aan lahayn beer koronto oo u dhaxaysa lammaanaha elektiroonigga ah ee u dhigma, farqiga gudbinta waxaa lagu soo bandhigayaa cabbirka goobta korontada ee codsatay.
Saddexaad, muhiimadda nambarka hadhka iyo wareegyada la xidhiidha. Lambarka shading waxaa loola jeedaa inta ay le'eg tahay ADF waxay shaandhayn kartaa iftiinka, lambarka hadhka weyn, ayaa yareynaya gudbintaADF, Marka loo eego baahiyaha alxanka ee kala duwan, dooro lambarka hadhka saxda ah, waxay u oggolaan kartaa alxanka inuu ilaaliyo muuqaal wanaagsan inta lagu jiro shaqada, wuxuu si cad u arki karaa barta alxanka wuxuuna hubin karaa raaxada wanaagsan, wuxuu ku habboon yahay hagaajinta tayada alxanka.Lambarka hadhka ayaa ah tilmaame farsamo oo muhiim ah oo ku jira ADF, marka loo eego waraaqaha u dhexeeya saamiga gudbinta ee ADF iyo lambarka hadhka ee heerka qaran ee ilaalinta indhaha alxanka, iftiinka muuqda, ultraviolet iyo saamiga gudbinta infrared ee nambar kasta oo hadhka waa inuu buuxiyaa shuruudaha heerka.
Afar, isku-xidhka isku-darka crystal dareeraha ah.Daaqadda ADF waxay ka kooban tahay muraayado dahaaran, laba qaybood oo dareere ah oo nalka iftiinka crystal ah iyo gabal muraayad ilaalin ah (fiiri sawirka 2), dhammaantood waxay ka tirsan yihiin walxaha galaaska, oo si fudud loo jebin karo, haddii xiriirka u dhexeeya uusan adkeyn, hal mar. Dareeraha alxanka wuxuu ku firdhiyaa isku-darka kristanta dareeraha ah, waxay keeni kartaa isku-dhafka crystal dareeraha ah inuu dillaaco, wuxuu dhaawici doonaa indhaha alxanka, sidaas darteed, adkeynta isku-xidhka isku-dhafka dareeraha dareeraha ah waa tilmaame badbaado oo muhiim ah ADF.Tijaabooyin badan ka dib, isticmaalka shisheeye A, B laba qaybood oo koollo ah, marka loo eego habka saamiga 3: 2 ee jawiga vacuum ka dib markii la walaaqo, jawiga nadiifinta heerka 100 iyadoo la adeegsanayo mashiinka dhejiska tooska ah ee bixinta iyo isku xidhka, si loo hubiyo in Astaamaha indhaha ee isku dhafka dareeraha dareeraha ee ADF ilaa en379-2003 iyo shuruudaha caadiga ah ee laxiriira, si loo xalliyo habka isku dhafka kristal dareeraha.
