LCD zaub screen yog cov khoom siv tshaj plaws hauv peb lub neej txhua hnub thiab kev ua haujlwm.Nws tuaj yeem pom hauv computers, TVs, mobile devices, thiab ntau yam khoom siv hluav taws xob.Cov kua siv lead ua kua module tsis tsuas yog muab cov txiaj ntsig zoo pom, tab sis kuj xa cov ntaub ntawv los ntawm nws lub ntsiab interface.Kab lus no yuav tsom mus rau lub ntsiab interface thiab cov khoom piav qhia ntawm Tft Display.
Lub ntsiab interface ntawm Tft Display yog siv los ntawm kev sib txawv interface technologies.Qee qhov kev sib txuas thev naus laus zis suav nrog RGB, LVDS, EDP, MIPI, MCU, thiab SPI.Cov thev naus laus zis interface no ua lub luag haujlwm tseem ceeb hauv kev tsim thiab ua haujlwm ntawm LCD cov ntxaij vab tshaus.
RGB interface yog ib qho ntawm feem ntau LCD zaub screen interfaces.Nws tsim cov duab los ntawm pixels ntawm peb xim: liab (R), ntsuab (G), thiab xiav (B).Txhua pixel sawv cev los ntawm kev sib txawv ntawm peb cov xim yooj yim, uas ua rau muaj xim zoo nkauj.RGB interfaces muaj nyob rau ntawm ntau lub computer saib thiab cov ntxaij vab tshaus TV.
Lub LVDS (Low Voltage Differential Signaling) interface yog ib qho kev sib txuas siv tshuab siv rau cov khoom siv ua kua siv lead ua kua.Nws yog ib tug low-voltage differential teeb liab technology interface.Ib txoj kev xa xov hluav taws xob digital video tsim los kov yeej qhov tsis txaus ntawm kev siv hluav taws xob siab thiab siab EMI electromagnetic cuam tshuam thaum xa cov ntaub ntawv broadband siab me ntsis ntawm qib TTL.LVDS tso zis interface siv lub viav vias tsis tshua muaj hluav taws xob (txog 350mV) txhawm rau xa cov ntaub ntawv sib txawv ntawm ob lub PCB kab lossis ib khub ntawm cov kab sib npaug, uas yog, qhov sib txawv ntawm cov teeb liab sib txawv.Kev siv LVDS tso zis interface tso cai rau cov teeb liab kis tau los ntawm cov kab sib txawv PCB lossis cov kab sib npaug ntawm tus nqi ntawm ntau pua Mbit / s.Vim yog siv cov kev siv hluav taws xob tsawg thiab tsis tshua muaj kev tsav tsheb tam sim no, tsis muaj suab nrov thiab kev siv hluav taws xob tsawg tau tiav.Nws yog tsuas yog siv los ua kom cov ntaub ntawv sib kis ceev ntawm lub vijtsam thiab txo qhov cuam tshuam ntawm electromagnetic.Los ntawm kev siv LVDS interface, LCD cov ntxaij vab tshaus tuaj yeem xa cov ntaub ntawv ntau ib txhij thiab ua tiav cov duab zoo dua.
EDP (Embedded DisplayPort) interface yog lub cim tshiab ntawm Tft Display interface thev naus laus zis rau cov khoos phis tawj thiab ntsiav tshuaj.Nws muaj qhov zoo ntawm qhov siab bandwidth thiab cov ntaub ntawv hloov pauv siab, uas tuaj yeem txhawb nqa kev daws teeb meem siab, siab refresh npaum li cas thiab kev ua haujlwm zoo dua xim.Nws yog tsuas yog siv los ua kom cov ntaub ntawv sib kis ceev ntawm lub vijtsam thiab txo qhov cuam tshuam ntawm electromagnetic.Los ntawm kev siv LVDS interface, LCD cov ntxaij vab tshaus tuaj yeem xa cov ntaub ntawv ntau ib txhij thiab ua tiav cov duab zoo dua.Lub EDP interface ua rau lub vijtsam LCD muaj qhov pom kev zoo dua ntawm cov khoom siv txawb.
MIPI (Mobile Industry Processor Interface) yog tus qauv sib txuas rau cov khoom siv txawb.MIPI interface tuaj yeem xa cov ntaub ntawv zoo video thiab cov duab nrog kev siv hluav taws xob tsawg thiab bandwidth siab.Nws yog dav siv nyob rau hauv LCD cov ntxaij vab tshaus ntawm mobile pab kiag li lawm xws li smartphones thiab ntsiav tshuaj.
MCU (Microcontroller Unit) interface feem ntau yog siv rau qee lub zog qis, tsis muaj kev daws teeb meem Tft Displays.Nws yog feem ntau siv hauv cov khoom siv hluav taws xob yooj yim xws li lub laij lej thiab cov ntse saib.MCU interface tuaj yeem tswj cov zaub thiab ua haujlwm ntawm LCD zaub screen zoo thaum muaj kev siv hluav taws xob tsawg.Cov ntaub ntawv xa tawm muaj xws li 8-ntsis, 9-ntsis, 16-ntsis thiab 18-ntsis.Cov kev sib txuas tau muab faib ua: CS /, RS (xaiv xaiv), RD /, WR /, thiab tom qab ntawd cov ntaub ntawv kab.Qhov zoo yog: yooj yim thiab yooj yim tswj, tsis muaj moos thiab synchronization teeb liab yuav tsum tau.Qhov tsis zoo yog: nws siv GRAM, yog li nws nyuaj rau ua tiav lub vijtsam loj (QVGA lossis siab dua).
SPI (Serial Peripheral Interface) yog ib qho yooj yim thiab feem ntau siv tshuab interface siv los txuas qee lub khoos phis tawj me me, xws li smartwatches thiab portable devices.SPI interface muab ceev ceev thiab cov pob me me thaum xa cov ntaub ntawv.Txawm hais tias nws cov zaub zoo kuj tsis tshua muaj, nws yog qhov tsim nyog rau qee cov khoom siv uas tsis muaj qhov xav tau siab rau cov teeb pom kev zoo.Nws tso cai rau MCU thiab ntau yam khoom siv peripheral sib txuas lus hauv kev sib pauv cov ntaub ntawv.SPI muaj peb qhov kev sau npe: tswj kev sau npe SPCR, tus lej sau npe SPSR thiab cov ntaub ntawv sau npe SPDR.Cov khoom siv peripheral feem ntau suav nrog lub network tswj, Tft Display tsav tsheb, FLASHRAM, A / D converter thiab MCU, thiab lwm yam.
Txhawm rau ua kom tiav, lub ntsiab interface ntawm LCD npo npo npog ntau yam kev sib txuas thev naus laus zis xws li RGB, LVDS, EDP, MIPI, MCU thiab SPI.Sib txawv interface technologies muaj ntau daim ntawv thov nyob rau hauv txawv Tft Displays.Kev nkag siab txog cov yam ntxwv thiab kev ua haujlwm ntawm LCD npo interface thev naus laus zis yuav pab peb xaiv cov khoom siv ua kua siv lead ua kua uas haum rau peb cov kev xav tau, thiab siv tau zoo dua thiab nkag siab cov ntsiab lus ua haujlwm ntawm LCD cov ntxaij vab tshaus.
