Hababka Hawlgelinta LCD
Maroojin Nematic (TN), Super maroojin Nematic (STN), Magdhawga Filimka STN (FSTN), iyo Midabka STN (CSTN) waa ereyada loo isticmaalo in lagu qeexo afar nooc oo ah Bandhigyada Dareereyaasha ah, mid kastaana maroojinayo jihada iftiinka dhex mara dareeraha. Qaab dhismeedka Crystal Display si ka duwan si uu u saameeyo isbarbardhigga iyo midabaynta.Waxaan sidoo kale is barbar dhignaa midabaynta, xaglaha daawashada, iyo kharashyada u dhexeeya tignoolajiyada.
Super maroojin Nematic (STN) LCDs
In kasta oo laga yaabo in LCD-yada qalloocan ee Nematic-yada loo kaxeeyo qaab waqti badan la isku daray si loo kordhiyo tirada macluumaadka la soo bandhigay, haddana way xaddidan yihiin marka la eego isbarbardhigga oo yaraada iyo xagal daawashada xaddidan.Si loo gaaro bandhigyo badan oo la isku daray, tignoolajiyada supertwist ayaa la isticmaalay.
Super maroojin Nematic LCD's waxay leeyihiin leexasho ka weyn 90 laakiin ka yar 360 digrii.Hadda inta badan bandhigyada STN waxaa lagu sameeyaa maroojin inta u dhaxaysa 180 iyo 270 darajo.Xaglaha qalloocan ee sare waxay sababaan qaloocyada marinka jaranjarada kuwaaso isu soo dhawaada koronto-dhaliyeyaasha.Heerarka sare waxay u oggolaanayaan in la gaaro heerar ka badan 32.
Bandhigga noocan oo kale ah, walxaha LC-gu waxay maraan wax ka badan 90 ° oo saxan ilaa saxan;Qiimaha caadiga ah wuxuu u dhexeeyaa 180 ilaa 270 °.Polarizers-ka kiiskan laguma rakibin isbarbar dhigga LC ee dusha sare ee halkii xagal.Unuggu, sidaas darteed, kuma shaqeeyo mabda'a "hagitaan" iftiin, sida ku jira LCD-yada Maroorsan ee Nematic, laakiin taa beddelkeeda mabda'a birefringence.Booska polarizers, dhumucda unugyada, iyo birefringence ee LC ayaa si taxadar leh loo doortay si ay u keento midab gaar ah ee gobolka "off".Caadi ahaan, kani waa jaale-cagaar si loo kordhiyo saamiga isbarbardhigga.LC-ga unugga ku jira waa "la-maroojin" taasoo siin doonta awoodda isticmaalka xadiga badan ee isku dhufashada.Marka maroojintu korodho, molecules-yada LC ee dhexda lakabka waxay la jaanqaadaan goobta korantada ee codsatay isbeddello yaryar oo danab ah.Tani waxay dhalinaysaa gudbinta aad u kacsan vs. qalooca danab, taasoo u oggolaanaysa ilaa 240-line isku dhufasho.
Tignoolajiyada STN waxay ku timaadaa laba midab, Green STN iyo Silver STN.STN-cagaarku waxa uu leeyahay jilayaal madow/violet madow oo asal ahaan cagaar ah.STN-Silver wuxuu leeyahay xarfo buluug madow / madow oo asal ahaan qalin ah.Waxay ku taallaa waddada badhtankeeda ilaa qiimaha, laakiin waxay leedahay tayada muuqaal aad u wanaagsan.Kala duwanaanshuhu wuxuu la mid yahay tignoolajiyada TN.
Filimka Magdhawga ah ee Super Maroojin Nematic (FSTN) LCDs
Horumarkii ugu dambeeyay ayaa ahaa soo bandhigida bandhigyada Filimka Magdhowga ah ee Super Twisted Nematic (FSTN).Tani waxay ku daraysaa filimka dib u dhigista bandhigga STN kaas oo magdhow u ah midabka lagu daray saamaynta birefringence.Tani waxay u oggolaaneysaa bandhig madow iyo caddaan ah in la soo saaro oo bixiya kala duwanaansho sare iyo xagal daawasho ballaaran.
Farsamada FSTN waxay ku timaadaa hal midab, jilayaal madow oo asal ahaan caddaan / cawl ah.Saddexda teknooloji ee halkan ku taxan, waa tan ugu qaalisan, laakiin waxay leedahay xaglo daawasho oo wanaagsan oo ka duwan tignoolajiyada STN ee kor ku xusan.
