Hoʻolauna ʻia ka pilina LVDS o ka pale LCD TFT-LCD

ʻO ka wehewehe ʻana o ka LVDS Interface

ʻO ka wehewehe ʻana o ka interface LVDS e pili ana i ka hana pine interface hopena hoʻokomo LVDS ma ka ʻaoʻao LCD panel, hiki ke aʻo ʻia ma o ka nānā ʻana i ka ʻikepili hale hana mua o ka pale LCD (i kapa pinepine ʻia ʻo ka puke kikoʻī pale). ʻOiai he ʻokoʻa nā kūlana Pelekania like ʻole o ka hana interface pale LCD, akā ʻaʻole paʻakikī ke ʻike i kēlā, e hoʻoholo ana ma ke ʻano o kāna mau leka koʻikoʻi a me nā helu, No ka laʻana, kahi pale LCD kumu hoʻohālike CLAA170EA02, e nānā i ka papa wehewehe interface i hāʻawi ʻia e ka mea hana, e like me ka mea i ʻike ʻia mai kahi kolamu pōkole ma ka ʻōlelo Pelekania, me RXO a me RXE, loaʻa i kēlā me kēia kahawai ka helu "0" ~ "3" hōʻailona ʻikepili hui, a he 1 set o nā hōʻailona uaki (RXOC a i ʻole RXEC), Hōʻike kēia he pale 30-pin, pālua, 8-bit ka pale LCD, ʻaʻole paʻakikī hoʻi ke ʻike i kāna hana pine, ʻo ia hoʻi, ʻo "RXO0-" ke hōʻike nei i ka set mua o ka ʻikepili 1-, ʻo "RXO0 +" ʻo ia hoʻi ka set mua o ka ʻikepili: 1 +; Hōʻike ʻo "RXE0-" i ka lua o ka hoʻonohonoho ʻikepili 1-, hōʻike ʻo "RXE0 +" i ka lua o ka hoʻonohonoho ʻikepili 1 +, ke koena, a pēlā aku. ʻO nā hiʻohiʻona o ka interface LVDS ʻo LVDS kahi ʻōlelo Pelekane pōkole "Low Voltage Differential Signaling" ʻo ia hoʻi ka hōʻailona ʻokoʻa haʻahaʻa haʻahaʻa. Lanakila ʻo LVDS i nā hemahema o ka hoʻouna ʻana i ka hoʻohana ʻana i ka mana kiʻekiʻe broadband a me ka hoʻopilikia electromagnetic EMI i ke ʻano pae TTL, a he ʻano hoʻouna hōʻailona wikiō kikohoʻe. Hoʻohana ka interface output LVDS i kahi swing voltage haʻahaʻa loa (ma kahi o 350mV) e hoʻouna i ka ʻikepili ma o ka ʻokoʻa ma nā uea PCB ʻelua a i ʻole nā ​​​​kaula kaulike. Hoʻouna ka interface LVDS i ka hōʻailona ma kahi PCB ʻokoʻa a i ʻole ke kaula kaulike ma ka wikiwiki o nā haneli megbits i kekona. Ma muli o ke ʻano haʻahaʻa voltage a me ke ʻano hoʻokele haʻahaʻa, loaʻa iā ia nā pono o ka walaʻau haʻahaʻa a me ka hoʻohana ʻana i ka mana haʻahaʻa. Ma ke TV kala LCD, hoʻohana ka laina LVDS i ke kaula kaulike, ʻo ia ka laina pālua wili. ʻO ka ʻāpana kaapuni LVDS interface ʻo LCD kala TV a i ʻole ka hōʻike kala ma ka wehewehe mua ʻana o nā hōʻailona hoʻokomo (e like me ke TV, AV, a pēlā aku), no ka loaʻa ʻana o ka hōʻailona RGB, ʻo kāna kaʻina hana like ia me ke TV kala maʻamau, a laila ma o ka hoʻololi RGB-LVDS, hoʻopuka i ka hōʻailona LVDS, i hoʻouna ʻia i ka pale LCD. ʻOiai ʻo ka TFT ma ka pale LCD e ʻike wale i ka hōʻailona TTL (RGB), pono ka LVDS i hoʻouna ʻia i ka pale LCD e wehewehe i ka hōʻailona TTL. Hiki ke ʻike ʻia he ʻelua ʻāpana o ka kaapuni interface LVDS: ka kaapuni interface output LVDS ma ka ʻaoʻao motherboard (LVDS transmitter), a me ka kaapuni interface input LVDS (LVDS receiver) ma ka ʻaoʻao panel LCD. Hoʻololi ka terminal hoʻouna LVDS i ka hōʻailona TTL i ka hōʻailona LVDS, a laila hoʻouna i ka hōʻailona i ka LVDS decoding IC ma ka ʻaoʻao panel LCD ma o ke kaula lālani a i ʻole ke kaula palupalu ma waena o ka panel drive a me ka panel LCD), e hoʻololi ana i ka hōʻailona serial i kahi hōʻailona like o ka pae TTL, a laila hoʻouna iā ia i ka LCD timing control a me ke kaapuni drive.
