Cov xov tooj ntawm tes, tseem hu ua cov ntxaij vab tshaus, yog siv los tso saib cov duab thiab xim.Lub vijtsam loj yog ntsuas diagonally, feem ntau yog ntiv tes, thiab hais txog qhov ntev ntawm lub vijtsam.Cov khoom siv tshuaj ntsuam Nrog kev maj mam nrov ntawm lub xov tooj ntawm tes xim xim, cov khoom siv ntawm lub xov tooj ntawm tes tau dhau los ua qhov tseem ceeb.
Cov ntxaij vab tshaus ntawm cov xov tooj ntawm tes sib txawv vim qhov sib txawv LCD zoo thiab kev tshawb fawb thiab kev tsim kho tshuab.Muaj kwv yees li TFT, TFD, UFB, STN thiab OLED.Feem ntau, cov xim ntau koj tuaj yeem tso saib, cov duab ntau dua, thiab cov khaubncaws sab nraud povtseg ntau dua.
Cov khoom siv tshuaj ntsuam
Nrog rau qhov maj mam nrov ntawm lub xov tooj ntawm tes xim npo, cov khoom siv ntawm lub xov tooj ntawm tes screen tau dhau los ua qhov tseem ceeb.Cov ntxaij vab tshaus ntawm cov xov tooj ntawm tes sib txawv vim qhov sib txawv LCD zoo thiab kev tshawb fawb thiab kev tsim kho tshuab.Muaj kwv yees li TFT, TFD, UFB, STN thiab OLED.Feem ntau, cov xim ntau koj tuaj yeem tso saib, cov duab ntau dua, thiab cov khaubncaws sab nraud povtseg ntau dua.
Ntxiv rau cov pawg no, lwm cov LCDS tuaj yeem pom ntawm qee lub xov tooj ntawm tes, xws li Nyiv lub SHARP GF screen thiab CG (nruam crystalline silicon) LCD.GF yog ib qho kev txhim kho ntawm STN, uas tuaj yeem txhim kho qhov ci ntawm LCD, thaum CG yog qhov ua tau zoo thiab siab zoo LCD, uas tuaj yeem ncav cuag qhov kev daws teeb meem ntawm QVGA (240 × 320) pixels.
Fold TFT npo
TFT (Thin Film field effect Transistor) yog ib hom active matrix kua siv lead ua zaub (LCD).Nws tuaj yeem "qhib" tswj tus kheej pixels ntawm lub vijtsam, uas tuaj yeem txhim kho lub sijhawm tshuaj tiv thaiv zoo heev.Feem ntau, cov tshuaj tiv thaiv lub sij hawm ntawm TFT yog ceev ceev, txog 80 milliseconds, thiab lub pom lub kaum sab xis yog loj, feem ntau muaj peev xwm ncav cuag 130 degrees, feem ntau yog siv nyob rau hauv high-end khoom.Lub thiaj li hu ua nyias zaj duab xis teb nyhuv transistor txhais tau hais tias txhua lub LCD pixel taw tes ntawm lub LCD yog tsav los ntawm cov zaj duab xis transistor integrated nyob rau hauv lub rov qab.Yog li muaj peev xwm ua tiav kev kub ceev, siab ci, siab sib piv cov ntaub ntawv screen.TFT belongs rau lub active matrix kua siv lead ua zaub, uas yog tsav los ntawm lub "active matrix" nyob rau hauv technology.Cov txheej txheem yog siv cov transistor electrode ua los ntawm nyias zaj duab xis technology, thiab siv cov txheej txheem scanning "kub rub" los tswj qhov qhib thiab qhib ntawm txhua qhov chaw pom.Thaum lub teeb ci irradiates, nws thawj zaug ci ntsa iab los ntawm sab polarizer thiab ua lub teeb nrog kev pab los ntawm cov kua siv lead ua kua molecules.Lub hom phiaj ntawm cov zaub yog ua tiav los ntawm shading thiab kis lub teeb.
Tft-lcd Cov kua siv lead ua kua yog cov yeeb yaj kiab nyias nyias transistor hom kua siv lead ua zaub, tseem hu ua "xim tiag" (TFT).TFT kua siv lead ua kua yog muab nrog ib tug semiconductor hloov rau txhua pixel, txhua pixel tuaj yeem tswj tau ncaj qha los ntawm cov mem tes, yog li txhua qhov ntawm tus kheej yog tus kheej, thiab tuaj yeem tswj tau tsis tu ncua, tsis tsuas yog txhim kho cov tshuaj tiv thaiv ceev ntawm lub vijtsam zaub, tab sis kuj tuaj yeem ua tau. tswj cov xim xim kom raug, yog li cov xim ntawm TFT kua siv lead ua muaj tseeb dua.TFT kua siv lead ua kua zaub yog tus cwj pwm los ntawm qhov ci ci zoo, qhov sib txawv siab, kev nkag siab zoo ntawm txheej, xim ci, tab sis kuj tseem muaj qee qhov tsis zoo ntawm kev siv hluav taws xob thiab tus nqi.TFT kua siv lead ua thev naus laus zis tau nrawm rau kev txhim kho ntawm lub xov tooj ntawm tes xim tshuaj ntsuam.Ntau lub cim tshiab ntawm cov xov tooj ntawm tes xim xim txhawb nqa 65536 xim zaub, thiab qee qhov txawm txhawb 160,000 xim zaub.Lub sijhawm no, qhov zoo ntawm qhov sib txawv siab thiab nplua nuj xim ntawm TFT yog qhov tseem ceeb heev.
