YLCD vs TFT Technology
Liquid Crystal Display lossis LCD yog ib qho cuab yeej siv los tso saib cov duab hluav taws xob ntawm lub vijtsam nyias thiab tiaj tus uas siv lub teeb pom kev zoo ntawm Liquid Crystals. Lub tshuab LCD tsis tawm lub teeb ncaj qha. LCD thev naus laus zis pom nws cov kev siv loj hauv ntau yam kev siv xws li computer saib, TV, dav hlau cockpit qhia thiab ntau qhov chaw. LCD thev naus laus zis tau siv los ntawm cov cuab yeej siv ntau yam xws li Video Players, Clocks, Watches, thiab Calculators thiab lwm yam. LCD thev naus laus zis tsis siv phosphors uas txhais tau tias yuav tsis muaj cov duab hlawv. LCD thev naus laus zis yog lub zog txuag hluav taws xob uas muaj kev nyab xeeb pov tseg piv rau CRT thev naus laus zis. Lub tshuab LCD ua rau siv hluav taws xob tsawg dua uas tso cai rau nws siv rau hauv cov khoom siv uas siv roj teeb rau lawv txoj haujlwm. Cov thev naus laus zis LCD tso cai rau siv ntau lub pixels nrog cov kua siv lead ua kua nyob rau hauv pem hauv ntej ntawm lub reflector rau kev tsim cov duab uas muaj xim lossis monochrome. LCD thev naus laus zis tau dhau los ntawm CRT thev naus laus zis uas tau tshwm sim los ntawm qhov tseeb tias cov xov tooj ntawm cov khoom siv siv LCD siv ntau dua piv rau cov khoom uas tau tsim los ntawm kev pab ntawm CRT technology.
TFT thev naus laus zis lossis Thin Film Transistor thev naus laus zis yog qhov sib txawv ntawm Liquid Crystal Display (LCD) uas ua rau siv cov Thin Film Transistor Technology uas txhim kho cov duab zoo dua piv rau Liquid Crystal Display Technology yooj yim. TFT tsis yog ib qho kev siv tshuab uas cais los ntawm LCD tab sis nws yog ib qho kev hloov pauv ntawm LCD thev naus laus zis. Hloov chaw ntawm kev siv cov wafers, TFT thev naus laus zis ua rau kev siv cov txheej txheem txuas ntxiv ntawm cov kua siv lead ua kua nrog ib txheej ntawm cov xim lim iav rau kev tswj cov xim raws li hluav taws xob tam sim no dhau ntawm TFT iav thiab xim lim iav. Kev ua haujlwm ntawm TFT thev naus laus zis tau pib xyoo 1960 txog xyoo 1980 tab sis cov no tsuas yog tsim los siv rau xyoo 2002 thaum cov nqi ntawm TFT thev naus laus zis mus txog qib qis ua rau nws zoo tagnrho rau kev thov hauv ntau yam khoom siv.
Nyob rau hauv cov thev naus laus zis qub ntawm kev nthuav tawm los ntawm LCD, cov teeb liab uas tau xa mus rau cais pixels tau tsis meej pem nrog cov teeb liab uas mus rau ib puag ncig pixels ua rau cov duab plooj thiab lwm yam teeb meem. TFT thev naus laus zis tau txo qhov teeb meem no vim tias hla cov cim tsis cuam tshuam rau qhov zoo ntawm cov zaub. Qhov zoo ntawm cov duab tau nce tso cai rau TFT-LCD coj kom zoo dua cov cuab yeej LCD yooj yim. Lub sijhawm teb ntawm LCD thev naus laus zis kuj yog qhov teeb meem. Lub sij hawm teb tsawg tso cai rau tsim cov duab nrawm thiab meej uas txav tau yooj yim thaum lub sij hawm teb siab ua rau qhov muag plooj thiab txo qhov zoo ntawm kev txav ceev ntawm cov ntxaij vab tshaus. Lub sij hawm teb rau TFT tsawg dua li ntawm LCD ua rau nws zoo dua rau kev saib cov khoom hauv kev txav. Cov kua dej tuaj yeem hloov tau yooj yim dua thiab ua rau lub vijtsam haum rau saib cov yeeb yaj kiab ua yeeb yaj kiab thiab cov xwm txheej kis las yam tsis muaj qhov muag plooj lossis txo qis hauv qhov zoo. LCD zaub siv transistor rau kev tsim cov duab thaum TFT yog ib txoj hauv kev tsim lub LCD. TFT ua tau zoo dua cov zaub zoo-ntseeg piv rau cov duab ntawm LCD. Txhua lub LCD zaub tau siv TFT thev naus laus zis niaj hnub no kom tau txais txiaj ntsig zoo dua.
