Hoʻākoakoa ka mea hoʻololi LVDS 20pin a i 20pin DuPont EDP i ke kaula LVDS hōʻikeʻike TV LCD

ʻIke kumu o ka uea uea LVDS connector ʻO ke kūlana interface lvds:

ʻO ka interface LVDS ka maʻamau interface maʻamau o ka LCD Panel, e lawe ana i ka Panel 8-bit ma ke ʻano he laʻana, me 5 mau set o nā laina hoʻoili, kahi 4 mau set he mau laina ʻikepili, e hōʻike ana iā Tx0 + / Tx0-… Tx3 + / Tx3-. Aia kekahi hōʻailona uaki, e hōʻike ana iā TxC + / TxC-. ʻO ka mea pili he 5 mau set o nā laina loaʻa ma ka hopena Panel. Inā he Panel 6-bit, aia wale nō 3 mau set o nā laina ʻikepili a me hoʻokahi set o nā laina uaki. ʻO ka interface LVDS, i ʻike ʻia hoʻi ʻo ka interface bus RS-644, he ʻenehana hoʻoili ʻikepili a me ka interface i ʻike wale ʻia i nā makahiki 1990. He hōʻailona ʻokoʻa haʻahaʻa haʻahaʻa ʻo LVDS, ʻo ke kumu o kēia ʻenehana ka hoʻohana ʻana i ka ʻikepili hoʻoili ʻokoʻa haʻahaʻa haʻahaʻa loa, hiki ke hoʻokō i ka pilina kiko i ke kiko a i ʻole ke kiko i ke kiko, me ka hoʻohana ʻana i ka mana haʻahaʻa, ka helu hewa code haʻahaʻa, ka crosstalk haʻahaʻa a me nā ʻano radiation haʻahaʻa, hiki i kāna medium hoʻoili ke pili keleawe PCB, a i ʻole ke kaula kaulike. Ua hoʻohana nui ʻia ʻo LVDS i nā ʻōnaehana me nā koi kiʻekiʻe no ka pono o ka hōʻailona, ​​​​ka jitter haʻahaʻa a me ke ʻano hoʻohālike like. I kēia manawa, ʻelua mau kūlana o ka ʻike loea LVDS kaulana: ke kūlana ANSA / TIA / EIA-644 o TIA / EIA (Telecommunications Industry Alliance / Electronics Industry Alliance), a me ke kūlana IEEE 1596.3. I Nowemapa 1995, ua hoʻolauna ʻia ke kūlana ANSI / TIA / EIA-644, i alakaʻi nui ʻia e nā hui semiconductor ʻAmelika. I Malaki 1996, ua paʻi ka IEEE i ke kūlana IEEE 1596.3. Ke nānā nei kēia mau kūlana ʻelua i nā ʻano uila o ka interface LVDS, ka pilina a me nā kikoʻī hoʻopau laina, a ʻaʻole maopopo ke kaʻina hana, ka medium hoʻoili a me ka voltage lako mana. Hiki ke hoʻokō ʻia ka LVDS me ka hoʻohana ʻana iā CMOS, GaAs a i ʻole nā ​​​​ʻenehana ʻē aʻe, me ka voltage lako mai + 5V a i + 3.3V a i ʻole haʻahaʻa; hiki i kāna medium hoʻoili ke lilo i pilina PCB a i ʻole ke kaula kūikawā. ʻO ka wikiwiki o ka hoʻoili ʻikepili maʻamau i ʻōlelo ʻia he 655Mbps, a ma ke kumumanaʻo, ma kahi laina hoʻoili ʻole palaho, ʻo ka wikiwiki o ka hoʻoili ʻana o LVDS a hiki i ka 1.923Gbps.—- Hoʻohana nui ʻia ke kūlana OpenLDI i nā kamepiula lawe lima, ʻo ka hapa nui o nā hōʻike LCD kamepiula lawe lima a me ka papa kikowaena ma waena o ka pilina pili e hoʻohana i ke kūlana OpenLDI. ʻO ke kumu o ke kūlana interface OpenLDI ʻo ia ka Low Voltage Differential Signaling (LVDS) interface, nona nā ʻano o ka wikiwiki, ka hoʻohana ʻana i ka mana haʻahaʻa, ka wikiwiki kiʻekiʻe, ke kumukūʻai haʻahaʻa, ka hoʻopilikia haʻahaʻa, hiki ke kākoʻo i ka hoʻonā kiʻekiʻe a pēlā aku. Hoʻohana nui ʻia ka interface LVDS i nā kelepona, nā kamaʻilio, nā mea uila mea kūʻai aku, nā kaʻa, nā mea lapaʻau, a ua kākoʻo ʻia e AMP, 3M, Samsung, Sharp, Silicon Graphics, a me nā mea ʻē aʻe. I mea e komo ai i ka hakahaka pākaukau, ua hoʻolauna ʻo NS i kahi chipset maʻamau OpenLDI hou DS90C387 a me ke kākoʻo DS90, no nā hōʻike LCD.
