Isiguquli se-LVDS 20pin ukuya ku-20pin seDuPont EDP sihlanganisa intambo ye-LVDS yesibonisi se-LCD TV

Ulwazi oluyisisekelo lwesixhumi sezintambo zezintambo ze-LVDS Izinga lesixhumi esibonakalayo se-lvds:

I-interface ye-LVDS iyindinganiso yokusebenzelana evamile ye-LCD Panel, ithatha i-8-bit Panel njengesibonelo, okuhlanganisa amasethi angu-5 emigqa yokudlulisela, lapho amasethi angu-4 eyimigqa yedatha, emele i-Tx0 + / Tx0-… Tx3 + / Tx3-.Kukhona futhi isignali yewashi, emele i-TxC + / TxC-.Okuhambisanayo kunamasethi angu-5 emigqa yokwamukela ekugcineni kwePhaneli.Uma kuyi-6-bit Panel, kukhona amasethi ama-3 kuphela emigqa yedatha nesethi eyodwa yemigqa yewashi.I-interface ye-LVDS, eyaziwa nangokuthi i-RS-644 bus interface, iwukudluliswa kwedatha kanye nobuchwepheshe bokuxhumana obavela kuphela ngeminyaka yawo-1990.I-LVDS iyisiginali yokuhlukanisa i-voltage ephansi, umnyombo walobu buchwepheshe ukusebenzisa idatha yokudlulisa ehlukanisiwe ngesivinini esiphansi kakhulu, ingafinyelela iphuzu ukuya kwelinye noma iphuzu lokuxhumanisa, ngokusetshenziswa kwamandla okuphansi, izinga lephutha lekhodi ephansi, i-crosstalk ephansi kanye izici eziphansi zemisebe, indawo yayo yokudlulisela ingaba uxhumano lwe-PCB yethusi, noma ikhebula lebhalansi.I-LVDS ibilokhu isetshenziswa kabanzi kumasistimu anezidingo eziphezulu zobuqotho besignali, i-jitter ephansi kanye nokumodela ngokubambisana.Njengamanje, ukucaciswa kobuchwepheshe okudumile kwe-LVDS kunamazinga amabili: izinga le-ANSA / TIA / EIA-644 le-TIA / EIA (Telecommunications Industry Alliance / Electronics Industry Alliance), kanye ne-IEEE 1596.3 standard.NgoNovemba 1995, indinganiso ye-ANSI / TIA / EIA-644 yethulwa, ikakhulukazi eholwa izinkampani ze-semiconductor zaseMelika.NgoMashi 1996, i-IEEE yashicilela indinganiso ye-IEEE 1596.3.Lawa mazinga amabili agxile ezicini zikagesi zesixhumi esibonakalayo se-LVDS, ukuxhumanisa kanye nokucaciswa kokuqedwa komugqa, futhi inqubo yokukhiqiza, i-transmission medium kanye ne-voltage yokuphakelwa kwamandla akucaci.I-LVDS ingasetshenziswa kusetshenziswa i-CMOS, i-GaAs noma obunye ubuchwepheshe, nge-voltage yokuhlinzeka kusuka ku-+ 5V kuya ku-+ 3.3V noma ngisho nangaphansi;i-transmission medium yayo ingaba uxhumano lwe-PCB noma ikhebula elikhethekile.Izinga elijwayelekile elinconywayo lokudluliswa kwedatha ngu-655Mbps, futhi ngokombono, emugqeni wokudlulisa ongaboli, izinga lokudlulisela kwe-LVDS lifika ku-1.923Gbps.—Izinga le-OpenLDI lisetshenziswa kakhulu kumalaptop, iningi lamalaptop abonisa i-LCD kanye nebhodi lomsingathi phakathi koxhumano. isikhombimsebenzisi samukela indinganiso ye-OpenLDI.Isisekelo se-OpenLDI interface standard yi-Low Voltage Differential Signaling (LVDS) interface, enezici zesilinganiso, ukusetshenziswa kwamandla aphansi, isivinini esikhulu, izindleko eziphansi, ukuphazamiseka okuphansi kwe-clutter, kungasekela ukulungiswa okuphezulu nokunye.Isixhumi esibonakalayo se-LVDS sisetshenziswa kabanzi kwezokuxhumana, kwezokuxhumana, kwezobuchwepheshe zabathengi, ezezimoto, amathuluzi ezokwelapha, futhi sisekelwe yi-AMP, 3M, Samsung, Sharp, Silicon Graphics, nezinye.Ukuze kungene isikhala sedeskithophu, i-NS yethule i-chipset entsha ye-OpenLDI ejwayelekile i-DS90C387 kanye nokwesekwa kwe-DS90, okuqondiswe ngqo kwizibonisi ze-LCD.
