Waxaan ognahay muddo dheer in ay jiraan saddex nooc oo maaddada ah: adag, dareere iyo gaas.Xarunta cufnaanta molecules dareeraha ah ayaa loo habeeyaa iyada oo aan wax joogto ah lahayn, laakiin haddii unugyadani ay dheer yihiin (ama siman yihiin), jihayntoodu waxay noqon kartaa mid joogto ah. Waxaan markaa u qaybin karnaa heerka dareeraha qaabab badan. Dareeraha aan lahayn jihada caadiga ah waxaa loogu yeeraa dareere si toos ah, halka dareeraha jihada jihada loo yaqaan 'liquid crystal', ama dareeraha dareeraha ah ee gaaban Kiristaalo dareere ah, kuwaas oo la helay 1888 by dhir-yaqaanka Australiyaanka ah ee Reinitzer, waa iskudhisyo organic ah oo leh nidaamyo molecular oo joogto ah oo u dhexeeya adkaha iyo dareeraha. Guud ahaan inta badan la isticmaalo qaab-dhismeedka dareeraha dareeraha ee dareeraha nematic dareeraha, qaabka molecular Bar dheer, ballac ah oo ku saabsan 1 nm ilaa 10 nm, hoos beeraha korantada ee kala duwan, dareeraha crystal molecules samayn doonaa habayn doonaa xeerar wareegey 90 digrii, wax soo saarkaKala duwanaanshaha gudbinta iftiinka, sidaas darteed awoodda ON / OFF ee hoos timaada farqiga u dhexeeya iftiinka iyo hooska, pixel kasta sida waafaqsan mabda'a xakamaynta, waxay samayn kartaa sawirka.
Mabda'a muraayadda dareeraha dareeraha ah waa crystal dareere ah oo hoos yimaada ficilka tamarta kala duwan waxay noqon doontaa iftiinka sifooyinka kala duwan ee hadda jira.LCD-ga physics-ku waxa uu u qaybsan yahay laba qaybood, mid waa Passive Passive (sidoo kale loo yaqaan Passive), LCD-ga noocan ahi laftiisu ma iftiimo, waxa uu u baahan yahay ilayska dibadeed, marka loo eego booska ilayska, waxana loo qaybin karaa milicsi iyo gudbinta nooca laba nooc.LCD dadban oo leh qiimo jaban, laakiin dhalaalka iyo isbarbardhigga maaha mid weyn, laakiin xagal wax ku ool ah waa yar yahay, ka yar midabka LCD Passive Pasive ee midabka, markaa midabku maaha mid dhalaalaya oo ku filan.Nooc kale ayaa ah isha korantada, gaar ahaan TFT (Thin FilmTransitor).LCD kasta dhab ahaantii waa transistor ayaa laga yaabaa inuu iftiimiyo, markaa si adag u hadla maaha LCD.Shaashadda LCD waxay ka kooban tahay khad badan oo LCD ah, muraayadda monochrome LCD, crystal dareere ah waa pixel, halka midabka dareeraha crystal-ka uu ka kooban yahay casaan, cagaar iyo buluug saddex LCD ah.Isla mar ahaantaana waxaa loo malayn karaa in ka dambeeya LCD kasta diiwaan 8-bit ah, qiyamka diiwaanka ayaa go'aamiya dhalaalka ee saddexda unug LCD siday u kala horreeyaan, laakiin qiimaha diiwaanku si toos ah uma wado iftiinka saddexda unug crystal dareere ah, laakiin "palette" si aad u booqato. Maaha wax macquul ah in la haysto diiwaanka jireed ee pixel kasta.Dhab ahaantii, hal saf oo diiwangelin ah ayaa qalabaysan, kuwaas oo ku xidhan saf kasta oo pixels markooda oo raraya waxa ku jira safkaas.
crystals-ka dareeraha ah waxay u egyihiin dareere, laakiin qaab-dhismeedkooda molecules-ku waxay u dhaqmaan sida kuwa adag. Sida biraha ku jira goobta magnetic, marka la hoos geeyo koronto dibadeed, molecules-yadu waxay sameeyaan habayn sax ah; molecules-ka dareeraha ah ee dareeraha ah ayaa u oggolaan doona iftiinka inuu dhex maro; Waddada iftiinka ee dhexmara crystal dareeraha ah waxaa lagu go'aamin karaa habaynta molecules-ka ka kooban, sifo kale oo adag. Sida molecules.Dabeecadda, faasasyada dhaadheer ee molecules-ulaha u eg ayaa qiyaas ahaan barbar socda. Liquid Crystal Display (LCD) marka hore waxay ka kooban tahay kiristaalo dareere ah oo ay tahay in lagu shubo inta u dhaxaysa laba diyaaradood oo lagu dhejiyay boosaska si ay si habboon u shaqeeyaan. Meelaha labada diyaaradood waa siman midba midka kale (90 darajo), taas oo ah, haddii molecules ku jira hal diyaarad ay la siman yihiin waqooyi-koonfur, molecules diyaaradda kale waxay la siman yihiin bari-galbeed, iyo molecules u dhexeeyalaba diyaaradood ayaa lagu qasbay inay u leexdaan 90-degree. Sababtoo ah iftiinku wuxuu u socdaalaa jihada molecules, sidoo kale waxaa lagu leexiyaa 90 darajo marka uu dhex maro crystal dareeraha. Laakiin marka danab lagu dhejiyo crystal dareeraha, molecules ayaa dib u habeynaya si toos ah, u oggolaanaya iftiinka inuu si toos ah u soo baxo iyada oo aan wax maroojin ah. Muuqaalka labaad ee LCDS waa in ay ku tiirsan yihiin filtarrada kala-soocida iyo iftiinka laftiisa.Iftiinka dabiiciga ah ayaa si aan kala sooc lahayn u kala baxa jihooyinka oo dhan. Xadadkani waxay sameeyaan shabag xannibaya dhammaan iftiinka aan la simanayn xadadkan.Xariiqda shaandhada dabaylaha ahi waa mid la siman kan hore, markaa si buuxda ayuu u xannibaa iftiinka dabaylaha. Kaliya haddii xadhkaha labada filtarrada ay si dhammaystiran u siman yihiin, ama haddii nalka laftiisa la maroojiyey si uu u dhigmo shaandhada labaad, iftiinka ayaa soo geli kara. .LCDS waxa ay ka kooban tahay laba filtar oo toosan, markaa waa in ay caadiyan xannibaan iftiin kasta oo isku dayaya in uu dhex galo molecules-ka dareeraha ah, oo ugu dambayntii dhex mara filterka labaad. Haddii, dhanka kale, danab lagu dabaqay crystal dareeraha ah, molecules-yada ayaa dib isu habeyn doona si iftiinku mar dambe maroojin doono, sidaas darteed Tusaale ahaan, Synaptics TDDI, waxay isku daraysaa kontaroolayaasha taabashada iyo muujinta darawalada hal jajab, yaraynta tirada qaybaha iyo fududaynta naqshadeynta. The ClearPad 4291waxay taageertaa nashqad khad isku-dhafan oo isku-dhafan oo ka faa'iidaysanaysa lakabka jira ee muraayadda dareeraha ah (LCD), taas oo meesha ka saaraysa baahida dareemayaasha taabashada discrete. architecture.Labada xal waxay ka dhigaan muraayadaha taabashada khafiifka ah waxayna soo bandhigaan iftiin dhalaalaya, iyagoo gacan ka geysanaya hagaajinta guud ahaan bilicda casriga ah iyo naqshadaha tablet-ka. kooxaha elektrodes-ka dahaaran iyo daah-furnaanta, jirka crystal dareere, electrode, galaas, filtarrada polarized iyo milicsiga.
