ʻO ka wehewehe LVDS Interface

ʻO ka wehewehe ʻana o ka LVDS e pili ana i ka LVDS input end interface pin function ma ka ʻaoʻao LCD panel, hiki ke aʻo maʻamau ma o ka nīnau ʻana i ka ʻikepili hale hana mua o ka pale LCD (i kapa pinepine ʻia ka puke kikoʻī pale). ʻOiai ʻokoʻa nā kūlana English o ka LCD pale interface hana, akā ʻaʻole paʻakikī ke ʻike i kēlā, e hoʻoholo ana ma ke ʻano o kāna mau leka kī a me nā helu, No ka laʻana, kekahi CLAA170EA02 hiʻohiʻona LCD pale, E nānā i ka papa kuhikuhi wehewehe interface i hāʻawi ʻia e ka mea hana, E like me ka hiki ke ʻike ʻia mai kahi kolamu pōkole ma ka ʻōlelo Pelekania, Me RXO a me RXE, Loaʻa i kēlā me kēia kahawai ka helu "0″ ~ 1 hōʻailona hōʻailona o ka pūʻulu "0″ ~ 1. (RXOC a i ʻole RXEC), Hōʻike kēia i ka pale LCD he 30-pin, pālua, 8-bit pale, ʻAʻole paʻakikī hoʻi e ʻike i kāna hana pin, ʻo ia hoʻi, "RXO0-" hōʻike i ka hoʻonohonoho mua o ka ʻikepili 1-, "RXO0 +" ʻo ia hoʻi ka hoʻonohonoho mua o ka ʻikepili: 1 +; "RXE0-" hōʻike i ka lua o ka ʻikepili 1-, "RXE0 +" hōʻike i ka lua o ka ʻikepili 1 +, ʻO ke koena, a pēlā aku. Hōʻike ka LVDS interface i ka LVDS he pōkole English "Low Voltage Differential Signaling" ʻo ia hoʻi ka hōʻailona ʻokoʻa haʻahaʻa haʻahaʻa. Ua lanakila ʻo LVDS i nā pōʻino o ka hoʻouna ʻana i ka broadband kiʻekiʻe ka mana mana a me ka EMI electromagnetic interference ma ke ʻano pae TTL, a he ʻano hoʻoili hōʻailona wikiō kikohoʻe. Hoʻohana ka LVDS output interface i ka haʻahaʻa haʻahaʻa haʻahaʻa (e pili ana i 350mV) e hoʻouna i ka ʻikepili ma ka ʻokoʻa ma nā uea PCB ʻelua a i ʻole nā kaula kaulike. Hoʻouna ka LVDS interface i ka hōʻailona ma kahi PCB ʻokoʻa a i ʻole ke kaula kaulike ma ka helu o nā haneli megbits i kekona. Ma muli o ka haʻahaʻa haʻahaʻa a me ke ʻano haʻahaʻa haʻahaʻa o kēia manawa, loaʻa iā ia nā pōmaikaʻi o ka haʻahaʻa haʻahaʻa a me ka hoʻohana haʻahaʻa haʻahaʻa. I ka LCD kala TV, LVDS laina hoʻohana 'ana i ke kaula kaulike ka hapanui, he wili laina laina maoli. ʻO ka LVDS interface circuit circuit LCD color TV a i ʻole ka waihoʻoluʻu hōʻike ma ka decoding mua o nā hōʻailona hoʻokomo (e like me TV, AV, etc.), no ka loaʻa ʻana o ka hōʻailona RGB, ʻo kāna kaʻina hana e like me ka TV kala maʻamau, a laila ma o ka hoʻololi ʻana o RGB-LVDS, hoʻopuka i ka hōʻailona LVDS, hoʻouna ʻia i ka pale LCD. Ma muli o ka ʻike ʻana o ka TFT i ka pale LCD i ka hōʻailona TTL (RGB), pono ka LVDS i hoʻouna ʻia i ka pale LCD e wehe i ka hōʻailona TTL. Hiki ke ʻike ʻia he ʻelua ʻāpana ka LVDS interface interface: ka LVDS output interface circuit ma ka ʻaoʻao motherboard (LVDS transmitter), a me ka LVDS input interface circuit (LVDS receiver) ma ka ʻaoʻao LCD panel. Hoʻololi ka LVDS transmitting terminal i ka hōʻailona TTL i ka hōʻailona LVDS, a laila hoʻouna i ka hōʻailona i ka LVDS decoding IC ma ka ʻaoʻao LCD panel ma o ke kaula laina a i ʻole ke kaula maʻalahi ma waena o ka panel drive a me ka panel LCD), e hoʻololi ana i ka hōʻailona serial i hōʻailona like o ka pae TTL, a laila e hoʻouna iā ia i ka mana LCD manawa a hoʻonohonoho i ka kaapuni kaʻa.
