ʻO ka hōʻailona TTL kahi hōʻailona maʻamau e hiki ai iā TFT-LCD ke ʻike, a ʻo ka LVDS TMDS i hoʻohana ʻia ma hope ua hoʻopaʻa ʻia ma kona kumu.ʻO ka laina hōʻailona TTL he 22 (ka liʻiliʻi, helu ʻole a me ka mana) i māhele ʻia i ka hōʻailona ʻekolu kala RGB, ʻelua HS VS kahua hoʻonohonoho hoʻonohonoho, hoʻokahi ʻikepili hiki ke hōʻailona DE he hōʻailona uaki CLK, kahi ʻokoʻa ka waihoʻoluʻu ʻekolu kumu o RGG e like me i ka helu o nā bits o ka pale, a me nā laina ʻikepili like ʻole (6 bits, A me 8-bit point) 6-bit pale a me 8-bit pale tri-color ʻo R0-R5 (R7) G0-G5 (G7) B0- ʻO ka hōʻailona tricolor B5(B7) he hōʻailona kala, ʻo ka misalignment ka mea e hōʻike ai i ka maʻi kala.
ʻO nā hōʻailona ʻē aʻe 4 (HS VS DE CLK) nā hōʻailona hoʻomalu, a ʻo ka hoʻopili hewa ʻana e hoʻomālamalama ʻole nā kiko pale a hōʻike pono ʻole.Ma muli o ka pae hōʻailona TTL e pili ana i 3V, he hopena maikaʻi loa ia i ka hoʻouna ʻana i ka lōʻihi o ke kiʻekiʻe kiʻekiʻe, a ʻilihune hoʻi ke kūʻē ʻana i ka hoʻopilikia.No laila aia ka pale LVDS interface, ʻoiai ke hoʻohana nei ka XGA ma luna o ka helu hoʻonā o ka pale i ke ʻano LVDS.
Hoʻokaʻawale ʻia ʻo LVDS i nā kahawai hoʻokahi, nā ʻāpana ʻelua, 6 mau ʻāpana, 8 mau ʻāpana, nā hakina, ke kumu a me ka mahele TTL.Hana ʻo LVDS (hōʻailona ʻokoʻa haʻahaʻa haʻahaʻa) ma o ka hoʻohana ʻana i kahi IC i hoʻolaʻa ʻia e hoʻopili i ka leka TTL hoʻokomo i kahi hōʻailona LVDS, 6 mau ʻāpana me 4 mau ʻokoʻa, 8 mau ʻāpana no 5 mau ʻokoʻa, nā inoa laina data d0-D0-D1-D2-CK- CK-Ck-Inā he pale 6-bit, ʻaʻohe D3 - ʻO ka D3 me ka hoʻonohonoho o nā hōʻailona, i hoʻopaʻa ʻia ma kā mākou papa kamepiula.Ma ka ʻaoʻao ʻē aʻe o ka pale, aia kekahi decoding IC me ka hana like, e hoʻohuli ana i ka hōʻailona LVDS i kahi hōʻailona TTL, a hoʻopau ka pale me ka hōʻailona TTL, no ka mea, ʻo ka pae hōʻailona LVDS e pili ana i 1V, a ʻo ke keakea ma waena o hiki i nā laina a me nā laina ke hoʻopau i kekahi i kekahi.No laila ikaika loa ka mana anti-jamming.
He kūpono ia no ka hoʻohana ʻana ma nā pale me ka helu code kiʻekiʻe ma muli o ka hoʻonā kiʻekiʻe.Ma muli o ke kiʻekiʻe loa o ka helu hoʻonā kiʻekiʻe 1400X1050 (SXGA) 1600X1200 (UXGA), ua hoʻomaikaʻi maikaʻi ʻia ka helu helu hōʻailona, e hilinaʻi ana i nā hoʻoili LVDS āpau, no laila ke hoʻohana nei lākou i kahi pānaʻi LVDS ʻelua ala e ho'ēmi i ka helu o kēlā me kēia LVDS.Paʻa paʻa hōʻailona
