Takaziva kwenguva yakareba kuti kune mhando nhatu dzezvinhu: yakasimba, mvura uye gasi. Pakati pehuwandu hwemamolekemu emvura inorongwa pasina nguva dzose, asi kana mamorekuru aya akareba (kana kuti flat), maitiro awo anogona kunge ari nguva dzose. . Mafoni, makarukureta zvinhu zvekristaro yemvura.Makristasi eLiquid, ayo akawanikwa muna 1888 nenyanzvi yezvemiti yekuAustria Reinitzer, makomisheni ane organic anogara akaronga mamolecular pakati pezvakaoma nezvinwiwa. yebhaa refu, hupamhi hunosvika 1 nm kusvika 10 nm, pasi pemasimu akasiyana emagetsi emazuva ano, mamorekuru emvura achaita kuronga mitemo inotenderedzwa 90 degrees, inogadzirwa.ing musiyano wekutenderera kwechiedza, saka simba ON / OFF pasi pemutsauko pakati pechiedza nemumvuri, pixel yega yega maererano nemutemo wekutonga, inogona kuumba mufananidzo.
Iyo musimboti wekuratidzwa kwekristaro yemvura ikristaro yemvura pasi pechiito chevoltage yakasiyana ichave mwenje weazvino maitiro akasiyana.LCD mufizikisi yakakamurwa kuita mapoka maviri, imwe iPassive Passive (inozivikanwawo sePassive), uye iyi mhando yeLCD pachayo haipenye, inoda kunze kwechiedza sosi, zvichienderana nenzvimbo yemwenje sosi, uye inogona kukamurwa kuita kuratidza uye kutapurirana mhando mbiri.Passive LCD ine mutengo wakaderera, asi kupenya uye kusiyanisa hakuna hombe, asi inoshanda Angle idiki, shoma Passive LCD color saturation yemuvara, saka ruvara rusina kupenya zvakakwana.Imwe mhando isimba remagetsi, kunyanya TFT (Thin FilmTransitor).Imwe neimwe LCD ndeyechokwadi transistor inogona kupenya, saka kunyatsotaura haisi LCD.LCD skrini inoumbwa neakawanda LCD mutsara array, mune monochrome LCD kuratidza, yemvura kristaro ipixel, nepo muruvara rwekristaro yerunyoro inoratidzira pixel yega yega ine tsvuku, yegirinhi uye yebhuruu matatu maLCD pamwechete.Panguva imwecheteyo inogona kufungidzirwa seseri kweLCD imwe neimwe 8-bit register, register values inotaridza kupenya kweatatu LCD unit zvakateerana, asi kukosha kwerejista hakufambisi zvakananga kupenya kweatatu liquid crystal cell, asi. ne “palette” yekushanya.Hazvisi chokwadi kuva nerejista yemuviri yepixel yega yega.Muchokwadi, mutsara mumwe chete wemarejista akashongedzerwa, ayo akabatana kune yega yega mutsara wemapikseli achitendeuka uye anotakura zviri mukati memutsara iwoyo.
Makristasi emvura anotaridzika uye anonzwa semvura, asi chimiro chawo checrystalline molecular inoita seyakasimba.Sesimbi dziri mugineti, kana ichiiswa kune imwe nzvimbo yemagetsi yekunze, mamorekuru anoumba kurongeka chaiko;Kana kurongeka kwemamorekuru kuchidzorwa nemazvo. , the liquid crystal molecules inobvumira chiedza kuti chipfuure;Nzira yechiedza kuburikidza nekiristaro yemvura inogona kutariswa nekurongeka kwemamorekuru anoiumba, humwe hunhu hwezvakaoma.Liquid crystals iorganic compounds inoumbwa netsvimbo refu- semamorekuru.Pamuzvarirwo, mademo marefu emamorekuru aya akafanana netsvimbo akada kufambirana.Liquid Crystal Display (LCD) inotanga ine Liquid crystals inofanira kudirwa pakati pendege mbiri dzakaiswa mitsetse kuti dzishande zvakanaka. perpendicular kune mumwe nemumwe (90 madhigirii), kureva kuti, kana mamorekuru ari mundege imwe anoenderana kuchamhembe-kumaodzanyemba, mamorekuru pane imwe ndege anoenderana kumabvazuva-kumadokero, uye mamorekuru pakatindege mbiri dzinomanikidzwa kupinda 90-degree twist.Nekuti chiedza chinofamba chichienda kune mamorekuru, zvakare chakamonyaniswa ne90 madhigirii sezvachinopfuura nemumvura crystal.Asi kana magetsi akaiswa kune crystal yemvura, mamorekuru anorongazve. vertically, kubvumira chiedza kuti chiyerere chakananga kunze pasina kumonyoroka.Chinhu chechipiri cheLCDS ndechekuti vanovimba nepolarizing filters uye chiedza pachacho.Chiedza chechisikigo chinosiyana zvisina tsarukano kumativi ose.Mitsetse iyi inoumba mambure anovharira chiedza chose chisingafambirane nemitsetse iyi.Iyo polarized filter line iri perpendicular kune yekutanga, saka inovhara zvachose chiedza chepolarized.Chete kana mitsetse yemasefa maviri yakanyatsoenderana, kana kuti chiedza pachacho chakamonyaniswa kuti chienderane nesefa yechipiri yepolarized, chiedza chinogona kupinda. .LCDS inoumbwa nemasefa maviri akadai vertically polarized filters, saka anowanzo kuvharira chero chiedza chiri kuedza kupinda.Zvisinei, nokuti mafirita maviri akazadzwa nemakristasi emvura akamonyoroka, mushure mekunge chiedza chapfuura nepasefa yekutanga, chakamonyoroka 90 degrees. neiyo liquid crystal molecules, uye pakupedzisira inopfuura nepasefa yechipiri. Kana, kune rumwe rutivi, voltage yaiiswa kune yemvura crystal, mamorekuru aizozvironga zvakare nenzira yekuti chiedza hachichazomonyaniswa, saka yaizovharwa nesefa yechipiri.Synaptics TDDI, semuenzaniso, inobatanidza zvinobata bata uye inotaridza madhiraivha kuita chip chimwe chete, kuderedza huwandu hwezvikamu uye kurerutsa magadzirirwo.The ClearPad 4291inotsigira hybrid multipoint inline design iyo inotora mukana weiyo iripo layer mune liquid crystal display (LCD), kubvisa kudiwa kwema discrete touch sensors.ClearPad 4191 inotora danho rinopfuura, uchishandisa maelectrodes aripo muLCD, nokudaro kuwana nzira iri nyore. Magadzirirwo ese ari maviri anoita kuti zviratidziro zvekubata zvitete uye zviratidzike kupenya, zvichibatsira kuvandudza kunaka kwese kwe smartphone uye piritsi dhizaini.Kune inotaridza TN (Twisted Nematic) liquid crystal display, chimiro chayo chine zvikamu zvinotevera: polarized sefa, girazi, maviri. mapoka emagetsi emagetsi akavharidzirwa uye akajeka, muviri wekristaro wemvura, electrode, girazi, polarized sefa uye kufungisisa.
