Kuunzwa kweiyo LVDS interface yeTFT-LCD LCD skrini

Iyo LVDS Interface Tsanangudzo

Iyo LVDS interface tsananguro inoreva iyo LVDS yekuisa yekupedzisira interface pini padivi reLCD panhivi, iyo inogona kazhinji kudzidzwa kuburikidza nekubvunza iyo yekutanga fekitori data yeLCD skrini (inowanzodaidzwa kuti iyo skrini yekutsanangurwa bhuku).Kunyangwe zvimiro zvakasiyana zvechirungu zveLCD screen interface basa zvakasiyana, Asi hazvina kuoma kuona izvozvo, tichitonga nehurongwa hwemabhii ayo akakosha nenhamba, Semuyenzaniso, imwe CLAA170EA02 modhi yeLCD skrini, Tarisa patafura yekutsanangura tafura yakapihwa ne mugadziri, Sezvinoonekwa kubva muchikamu chipfupi muChirungu, NeRXO uye RXE, Imwe neimwe chiteshi ine nhamba "0″ ~ "3" yeboka data chiratidzo, Uye ine 1 seti yewachi zviratidzo (RXOC kana RXEC), Izvi zvinoratidza kuti iyo LCD skrini ine 30-pini, mbiri, 8-bit skrini, Hazvina zvakare kuoma kuona basa repini, Kureva, “RXO0-” inomiririra seti yekutanga yedata 1-, “RXO0 +” zvinoreva seti yekutanga. yedata: 1 +;"RXE0-" inoratidza seti yechipiri yedata 1-, "RXE0 +" inoratidza seti yechipiri yedata 1 +, Iyo yese, zvichingodaro.Iyo LVDS interface inoratidzira LVDS ipfupi Chirungu "Low Voltage Differential Signaling" zvinoreva iyo yakaderera-kudzvinyirira chiratidzo chekusiyanisa.LVDS inokunda zvakaipira kuendesa Broadband yakakwira simba rekushandisa uye EMI electromagnetic kupindira muTTL level modhi, uye idhijitari vhidhiyo chiratidzo chekufambisa modhi.Iyo LVDS yekubuda interface inoshandisa yakaderera voltage swing (inenge 350mV) kufambisa iyo data nemusiyano pawaya mbiri dzePCB kana tambo dzekuenzanisa.Iyo LVDS interface inotumira chiratidzo pane inosiyanisa PCB kana bhavhari tambo pachiyero chemazana emamegbit pasekondi.Nekuda kweiyo yakaderera voltage uye yakaderera ikozvino dhiraivha modhi, ine zvakanakira yakaderera ruzha uye yakaderera simba kushandiswa.MuLCD ruvara rweTV, LVDS mutsara inoshandisa tambo tambo kazhinji, yakamonyoroka peya mutsara chaizvo.Iyo LVDS interface yedunhu chikamu LCD ruvara TV kana ruvara kuratidza pane yekutanga decoding yemasaini ekuisa (seTV, AV, nezvimwewo), kuti uwane iyo RGB chiratidzo, maitiro ayo ekugadzirisa akanyanya kufanana neyakajairwa ruvara TV, uye zvino kuburikidza neRGB-LVDS shanduko, inoburitsa LVDS chiratidzo, inotumirwa kuLCD skrini.Sezvo iyo TFT iri muLCD skrini inongoziva iyo TTL (RGB) chiratidzo, iyo LVDS inotumirwa kuLCD skrini inoda decoding chiratidzo cheTTL.Zvinogona kuoneka kuti LVDS interface yedunhu inosanganisira zvikamu zviviri: iyo LVDS yekubuda interface yedunhu padivi reamai (LVDS transmitter), uye LVDS yekupinda interface yedunhu (LVDS inogamuchira) padivi reLCD panhi.Iyo LVDS inotumira terminal inoshandura chiratidzo cheTTL kuita chiratidzo cheLVDS, yobva yaendesa chiratidzo kuLVDS decoding IC padivi reLCD padivi kuburikidza netambo yemutsara kana tambo inochinjika pakati pedhiraivha pani uye LCD pani), ichishandura serial chiratidzo kuita. chiratidzo chakafanana cheiyo TTL level, uye wozoitumira kune iyo LCD nguva yekutonga uye mazinga edhiraivha.
