Tsawg Voltage Differential Signaling siv cov khub sib txawv rau kev tiv thaiv suab nrov zoo.

Ib leeg-channel vs dual-channel LVDS - thaum twg koj xav tau dual?

Ib qho channel rau kev daws teeb meem qis dua; dual channel rau 1280 × 800 thiab siab dua.

Hom connector hom: FFC / FPC thiab JST ntawm 7 nti panels

Cable ntev kom zoo dua: LVDS khiav mus txog 1-2 meters ntseeg tau

Kev txhawb nqa kev daws teeb meem: yooj yim tuav 1024 × 600 thiab 1280 × 800

Cov txheej txheem twg thiab SoCs tso tawm LVDS ib txwm muaj

Ntau Rockchip, NXP i.MX, thiab muaj SoCs txhawb LVDS.
