Ihe ntụgharị LVDS 20pin ruo 20pin DuPont EDP na-achịkọta ihe ngosi LCD TV LVDS cable

Ihe ọmụma bụ isi nke eriri eriri njikọ LVDS ọkọlọtọ lvds interface:

The LVDS interface bụ nkịtị interface ọkọlọtọ nke LCD Panel, na-ewere 8-bit Panel dị ka ihe atụ, gụnyere 5 tent nke nnyefe ahịrị, ebe 4 tent bụ data ahịrị, na-anọchi anya Tx0 + / Tx0-… Tx3 + / Tx3-. Enwekwara mgbama elekere, na-anọchite anya TxC +/TxC-. Nke kwekọrọ na ya nwere 5 tent nke ahịrị ịnata na njedebe Panel. Ọ bụrụ na ọ bụ 6-bit Panel, enwere naanị ahịrị data 3 yana otu ahịrị elekere. Ihe interface LVDS, nke a makwaara dị ka interface ụgbọ ala RS-644, bụ nnyefe data na teknụzụ interface nke pụtara naanị na 1990s. LVDS bụ a ala voltaji dị iche iche mgbaàmà, isi nke a technology bụ iji nnọọ obere voltaji swing elu ọsọ dị iche iche nnyefe data, nwere ike nweta n'ókè na-atụ ma ọ bụ na-atụ aka njikọ, na obere ike oriri, obere koodu njehie ọnụego, obere crosstalk na ala radieshon àgwà, ya nnyefe usoro nwere ike ịbụ ọla kọpa PCB njikọ, ma ọ bụ itule eriri. A na-eji LVDS eme ihe n'ọtụtụ ebe na sistemụ nwere nnukwu ihe achọrọ maka iguzosi ike n'ezi akara, obere jitter na imekọ ihe. Ugbu a, nkọwa nka nka LVDS na-ewu ewu nwere ụkpụrụ abụọ: ọkọlọtọ ANSA / TIA / EIA-644 nke TIA / EIA (Telecommunications Industry Alliance / Electronics Industry Alliance), na ọkọlọtọ IEEE 1596.3. Na Nọvemba 1995, ewebata ọkọlọtọ ANSI / TIA / EIA-644, nke ụlọ ọrụ semiconductor America na-edu. Na Maachị 1996, IEEE bipụtara ọkọlọtọ IEEE 1596.3. Ụkpụrụ abụọ a na-elekwasị anya na njirimara eletriki nke interface LVDS, njikọ njikọ na njedebe ahịrị, na usoro mmepụta, nnyefe nnyefe na voltaji ọkụ ọkụ adịghị anya. Enwere ike itinye LVDS site na iji CMOS, GaAs ma ọ bụ teknụzụ ndị ọzọ, yana voltaji ọkọnọ sitere na + 5V ruo + 3.3V ma ọ bụ ọbụna ala; usoro nnyefe ya nwere ike ịbụ njikọ PCB ma ọ bụ eriri pụrụ iche. Ọkọlọtọ na-atụ aro data nnyefe ọnụego bụ 655Mbps, na na tiori, na a n'efu nnyefe akara, LVDS nnyefe ọnụego ruo 1.923Gbps.—-OpenLDI ọkọlọtọ na-ọtụtụ ebe na-eji na laptọọpụ, ọtụtụ laptọọpụ LCD ngosi na ndị ọbịa osisi n'etiti interface interface nakweere ụkpụrụ OpenLDI. Ndabere nke ọkọlọtọ OpenLDI interface bụ Low Voltage Differential Signaling (LVDS) interface, nke nwere njirimara nke ọnụego, obere ike oriri, oke ọsọ, ọnụ ala, obere nkwụsịtụ, nwere ike ịkwado mkpebi dị elu na ihe ndị ọzọ. A na-eji interface LVDS eme ihe na nkwukọrịta, nkwukọrịta, ngwa eletrọnịkị ndị ahịa, ụgbọ ala, ngwa ahụike, yana AMP, 3M, Samsung, Sharp, Silicon Graphics na ndị ọzọ kwadoro ya. Iji banye na oghere desktọpụ, NS ewebatala ọhụrụ OpenLDI ọkọlọtọ chipset DS90C387 na nkwado DS90, kpọmkwem maka ngosipụta LCD.
