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 kala duwan heerkulka gaar ah labada dareere iyo crystal laba sifo oo ka mid ah xaaladda maaddada, oo joogto ah. habaynta molecular ee xeryahooda organic, caadi ahaan loo isticmaalo crystal dareere wajiga of crystal dareere ah, xaaladda kelli waa usheeda 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 shido 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 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 codsado beer koronto oo aan lahayn garoon koronto oo u dhexeeya lammaanaha electrodes ee u dhigma, farqiga u dhexeeya gudbinta ayaa la soo bandhigay iyadoo loo eegayo cabbirka goobta korontada ee codsatay.
Saddexaad, muhiimadda nambarka hadhka iyo wareegyada la xidhiidha. Lambarka shading waxa loola jeedaa inta ay le'eg tahay ADF waxay shaandhayn kartaa iftiinka, lambarka hadhka ee weyn, ayaa yareeya 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.Nambarka 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.
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 tuubada nuugista sawir-qaadista, oo laga beddelay iska-caabiyaha muunadda oo loo beddelo signalka korantada, oo ay weheliso awoodda, 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-ka hooseeya si uu u soo saaro amarka wadista wareegga darawalka LCD.Wareegga darawalka 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 waxay damisaa tamarta sare muddo aad u yar gudaheed, si looga fogaado in danabka sare si joogto ah loogu shubo crystal dareere ah, waxyeelo u geysata chip crystal dareere ah, iyo koronto isticmaalka.Korantada DC ee dareeraha dareeraha wadista dareeraha, kaas oo soosaarkiisu la siman yahay wareegga shaqada, wuxuu u kaxeeyaa waalka iftiinka crystal dareeraha si uu u shaqeeyo.
Afar, isku xidhka isku darka crystal dareere 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, si sahlan loo jebiyo, haddii xiriirka u dhexeeya uusan adkeyn, hal mar. Dareeraha alxanka wuxuu ku firdhiyaa isku-darka kristanta dareeraha ah, waxay sababi kartaa isku-darka kristanta 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.
