Mashandiro anoita mvura

Liquid Crystal inoratidza (LCDs) yave chikamu chakakosha chehupenyu hwedu hwezuva nezuva, kubva kuSmartphones uye terevhizheni kuenda kuComputer Monitors uye Digital Sign. Izvi zvinoratidza zvinopa mifananidzo yakakwira-gadziriso ine mavara ehupenyu uye akanakisa kutarisa angles. Asi wakambozvibvunza here kuti iyo LCD Molecules inoshanda sei kugadzira zvinonetsa zvakadaro?

Pamwoyo weLCD iine mamaira ezvemvura, ayo akasarudzika mukukwanisa kwavo kuzviitira chikamu chakati pavanenge ari kuiswa munda yemagetsi. Aya mamorekuru anoumbwa kwenguva refu, tsvimbo-kunge midziyo ine ese maviri mvura uye yakasimba-senge zvivakwa. Muhurumende yavo yepanyama, mhandara yemanyorerwo emolileculy yakasarudzika, inoguma nekuonekwa kwasviba kana mwenje uchipfuura nepakati pavo.

Kuti unzwisise kuti LCD Molecules Shanda sei, ngatitariseizve chimiro chekutanga cheLCD Panel. Iyo ine maviri mahwendefa mahwendefa ane mutete wezvemvura yekremesi yemvura yakadzika pakati pavo. Iyo nzvimbo yemukati yeiyo imwe neimwe girazi mapuranga inobatanidzwa neyemagetsi yakajeka, iyo inobvumira munda wemagetsi kuti aiswe kune iyo yemvura yekristmas.

Iyo yemvura yekristaro mamalecules muLCD kazhinji yemhando mbiri: dzakamanikidzwa nemamisiti (tn) uye vertical alignment (VA). Mune TN LCD, mamorekuru anoenderana nekona chaiyo, kazhinji maGiredhi 90, pakati pemateti maviri emagirazi apo pasina munda wemagetsi unoiswa. Iyi gadziriro yakamonyana inobvumidza mwenje kuti ipfuure nepamhepo crystal layer uye usvike muoni. ( Ona Vhidhiyo pano )

Kana munda wemagetsi uchiiswa kuTN LCD, iyo mamaira emanyoreti ezvemvura anotanga kusanzwisisana, achizvinyudza mumunda wemagetsi. Izvi zvinogadziriswa zvinoshandura polarization yechiedza ichipfuura nepamhepo crystal layer, zvinobudirira kuvharira kubva pakusvika kune vanoona. Nekudzora munda wemagetsi, huwandu hwechiedza hunopfuura nepakati peLCD dzinogona kuve dzakanyatsorongwa, zvichikonzera mumazinga akasiyana ekujeka.

Kune rimwe divi, VA LCDs inoshanda zvakasiyana. Mune va LCD, iyo mamaira emhando yemanyoreti anotanga kuwiriraniswa nemutsara, perpendicular kune mahwendefa egirazi. Kana munda wemagetsi uchiiswa, mamorekuru akaiswa, achibvumira mwenje kuti ubudise nepamhepo crystal layer. Zvakafanana neTN LCDs, danho remhombwe rinogona kudzorwa nekugadzirisa munda wemagetsi, nekudaro kudzora kupenya.

Kuti uwedzere kuwedzeredza kuita kweLCDS, zvimwe zvikamu zvakadai semafirita emavara uye masisitimu ekudzokera kumashure anoiswa. Mafirita emavara anoshandiswa kugadzira iyo yaunoda ruvara rweGamut nekusarudza kuseya chiedza kupfuudza kuburikidza neyechivharo crystal layer. Systemsing masisitimu, kazhinji inoumbwa ne leds, ipa kuvhenekerwa kwekuvhenekerwa kweLCD Panel.

Mune pfupiso, LCD mamorekuru vanoshanda nekunyorera kuwirirana kwezvinhu zvemvura makristuru kuburikidza nekushandiswa kwemunda yemagetsi. Iyi yekudzorwa inodzora inobvumira iyo LCD kuti itongere chikamu chechiedza, zvichikonzera kuratidzwa kwemifananidzo nemavhidhiyo. Iko kugona kwekunyatso kudzora kutarisisa kwemanyorerwo emolilecules yakaita kuti LCDS imwe yeakakurumbira show matekiniki, kupa maono emhando yepamusoro mumhando dzakasiyana siyana.
