LCD LVDS interface yog dab tsi?

LVDS interface yog ib qho kev sib txuas lus sib txuas hauv LCD zaub interface. Nws Lub Npe Tag Nrho yog Tsawg Voltage Differential Signaling, uas yog qhov qis-voltage differential signaling technology interface. Nws yog txoj kev xa xov hluav taws xob digital video tsim los ntawm American NS (National Semiconductor Corporation) kom kov yeej qhov tsis txaus ntawm kev siv hluav taws xob loj thiab loj EMI electromagnetic cuam tshuam thaum xa cov ntaub ntawv broadband siab me ntsis los ntawm TTL qib hom.

Hauv LCD interface, LVDS tso zis interface siv lub viav vias qis heev (txog 350mV) los xa cov ntaub ntawv sib txawv ntawm ob lub PCB kab lossis ib khub ntawm cov kab sib npaug, uas yog, qhov sib txawv ntawm cov teeb liab sib txawv. Siv lub LVDS tso zis interface, lub teeb liab yuav kis tau ntawm tus nqi ntawm ob peb puas Mbit / s ntawm qhov sib txawv PCB kab los yog sib npaug cable. Vim yog txoj kev tsav tsheb tsis tshua muaj hluav taws xob thiab qis tam sim no, tsis muaj suab nrov thiab siv hluav taws xob tsawg tau tiav. Tam sim no, LVDS tso zis interface yog dav siv hauv LCD ntawm 17in thiab siab dua.
