Chosinthira cha LVDS cha 20pin mpaka 20pin DuPont EDP chimasonkhanitsa chiwonetsero cha TV cha LCD chingwe cha LVDS

Chidziwitso choyambira cha cholumikizira cha LVDS cholumikizira waya Muyezo wa mawonekedwe a LVDS:

Mawonekedwe a LVDS ndi muyezo wodziwika bwino wa LCD Panel, potengera chitsanzo cha 8-bit Panel, kuphatikiza ma seti 5 a mizere yotumizira, pomwe ma seti 4 ndi mizere ya data, yomwe ikuyimira Tx0 + / Tx0-… Tx3 + / Tx3-. Palinso chizindikiro cha wotchi, chomwe chikuyimira TxC + / TxC-. Chofananacho chili ndi ma seti 5 a mizere yolandirira kumapeto kwa Panel. Ngati ndi Panel ya 6-bit, pali ma seti atatu okha a mizere ya data ndi seti imodzi ya mizere ya wotchi. Mawonekedwe a LVDS, omwe amadziwikanso kuti RS-644 basi interface, ndi ukadaulo wotumizira deta ndi mawonekedwe womwe unangowonekera m'ma 1990. LVDS ndi chizindikiro chosiyana cha voltage yochepa, chinsinsi cha ukadaulo uwu ndikugwiritsa ntchito deta yosiyana ya voltage yotsika kwambiri, imatha kukwaniritsa kulumikizana kwa point to point kapena point to point, ndi kugwiritsa ntchito mphamvu zochepa, kuchuluka kwa zolakwika za code kochepa, crosstalk yochepa komanso mawonekedwe otsika a radiation, njira yake yotumizira ikhoza kukhala kulumikizana kwa PCB yamkuwa, kapena chingwe cholumikizira. LVDS yakhala ikugwiritsidwa ntchito kwambiri m'makina omwe ali ndi zofunikira kwambiri pakusunga chizindikiro, kugwedezeka kochepa komanso kugwirizanitsa. Pakadali pano, ukadaulo wotchuka wa LVDS uli ndi miyezo iwiri: muyezo wa ANSA / TIA / EIA-644 wa TIA / EIA (Telecommunications Industry Alliance / Electronics Industry Alliance), ndi muyezo wa IEEE 1596.3. Mu Novembala 1995, muyezo wa ANSI / TIA / EIA-644 unayambitsidwa, makamaka motsogozedwa ndi makampani aku America a semiconductor. Mu Marichi 1996, IEEE idasindikiza muyezo wa IEEE 1596.3. Miyezo iwiriyi imayang'ana kwambiri mawonekedwe amagetsi a LVDS interface, kulumikizana ndi mafotokozedwe oletsa mzere, ndipo njira yopangira, njira yotumizira ndi magetsi sizikumveka bwino. LVDS ikhoza kukhazikitsidwa pogwiritsa ntchito CMOS, GaAs kapena ukadaulo wina, ndi magetsi operekera kuyambira + 5V mpaka + 3.3V kapena kutsika; njira yake yotumizira ikhoza kukhala kulumikizana kwa PCB kapena chingwe chapadera. Mlingo wovomerezeka wotumizira deta ndi 655Mbps, ndipo m'malingaliro, mu mzere wotumizira wopanda kuwonongeka, kuchuluka kwa kutumiza kwa LVDS mpaka 1.923Gbps.—-Muyezo wa OpenLDI umagwiritsidwa ntchito kwambiri m'ma laputopu, ma laputopu ambiri LCD display ndipo bolodi lolowera pakati pa mawonekedwe olumikizirana limagwiritsa ntchito muyezo wa OpenLDI. Maziko a muyezo wa mawonekedwe a OpenLDI ndi mawonekedwe a Low Voltage Differential Signaling (LVDS), omwe ali ndi mawonekedwe a liwiro, kugwiritsa ntchito mphamvu zochepa, liwiro lapamwamba, mtengo wotsika, kusokoneza pang'ono, amatha kuthandizira mawonekedwe apamwamba ndi zina zotero. Mawonekedwe a LVDS amagwiritsidwa ntchito kwambiri mu kulumikizana kwa mafoni, kulumikizana, zamagetsi zamagetsi, magalimoto, zida zamankhwala, ndipo athandizidwa ndi AMP, 3M, Samsung, Sharp, Silicon Graphics, ndi ena. Kuti alowe mu desktop, NS yayambitsa chithandizo chatsopano cha OpenLDI standard chipset DS90C387 ndi DS90, makamaka paziwonetsero za LCD.
