Kev tsom xam ntawm industrace kev lag luam interface tshuab: qhov sib txawv ntawm LUVDS thiab HDMI thiab xaiv

1. Lub hauv paus rau phau ntawv

Hauv cov khoom siv tshuab hluav taws xob niaj hnub, LCD) ua pa tawm (LCD) pab li cov tseem ceeb tivthaiv rau tib neeg - tshuab sib cuam tshuam. Kev xaiv ntawm cov thev naus laus zis rau kev ua tau zoo thiab kev ntseeg tau. LVDs (tsawg - voltage sib txawv kos npe) thiab HDMI (siab - Txhais tau cov ntsiab lus multimedia) yog ob qho kev sib txuas lus sib cuam tshuam rauMuaj LCD, Txhua tus nrog cov yam ntxwv tshwj xeeb thiab siv cov xwm txheej.

1. Kev sib piv ntawm cov ntsiab lus techniples

2. 1.LVDS Interface Technical

Lvds siv lub teeb liab sib kis tshuab los xa cov ntaub ntawv los ntawm ib nkawm kev sib txuam ntawm cov paib, thiab muaj cov yam ntxwv hauv qab no:

Tsawg khiav hauj lwm voltage (feem ntau 1.2v),

Tus nqi sib kis tau txog li 1gbps lossis ntau dua,

Muaj zog tiv thaiv - Kev cuam tshuam lub peev xwm,

Tsawg siv hluav taws xob,

Luv kis tau deb (feem ntau tsis muaj ntau tshaj 10 meters).

2. 2.hdmi interface technical

HDMi yog cov digital interface tsim tshwj xeeb rau high - Txhais video thiab audio. Nws cov yam ntxwv tseem ceeb muaj:

Siv tmds encoding thev naus laus zis,

Txhawb synchronous kev sib kis ntawm video thiab audio,

Bandwidth txog 48 gbps (HDMI 2.1),

Txhawb nqa HDCP cov ntsiab lus tiv thaiv,

Kev nrug deb yog txwv los ntawm cov paib kev ua haujlwm (feem ntau 515 meters).

1. Kev sib piv ntawm cov kev ua tsis tau zoo

2. 1.Qhov kev coj ua

Hom phiaj xwm: Lvds tsuas kis cov ntaub ntawv video, thaum HDMI tuaj yeem kis suab, video, thiab tswj cov cim.

Qhov siab tshaj plaws: LVDs txhawb 1080p @ 60Zp @ 60Hz, thaum hdmi txhawb nqa txog 8k @ 60Hz.

Kev nrug deb: LVDs yog qhov tsim nyog rau kev ncua deb (<1m), thaum hdmi tuaj yeem ncav cuag li 15m (siv cov cable zoo).

2. 2.Txoj kev pom zoo

Kev lag luam hluav taws xob: LVDs 1.2V, HDMI 5V.

Kev Siv Fais Fab: LVDs feem ntau <100mw, HDMI kwv yees li 300mw.

Kev cuam tshuam Kuj: LVDs Outperforms HDMI.

3. 3.Mechanical Cwj Pwm

Txuas Hom: LVDs feem ntau siv 30 - lossis 50 - Pin Ribbon cable, thaum HDMI siv tus qauv 19 - tus pin interface.

Kev sib txuas kev ntseeg tau: LVDs yog qhov haum rau kev vibrating ib puag ncig.

1. Kev Ntsuam Xyuas Daim Ntawv Qhia Txog Kev Ntsuam Xyuas

2. 1.Ttepical applications ntawm LVDs

Muaj Panels,Kev Tu Mob TFT Cov cuab yeej siv, hauv - Tsheb Qhia Tawm, Aerospace cov twj paj nruag, sab nraum zoov muaj cov lus qhia.

Qhov Zoo:

Kev ruaj khov ua haujlwm nyob hauv cheeb tsam nrog kev cuam tshuam hluav taws xob muaj zog hauv hluav taws xob,

Haum rau cov xwm txheej yuav tsum tau ntev - sij hawm ua lag luam tas mus li,

Kev koom ua ke system yooj yim thiab kev sib hloov,

2. 2. Luam ntawm HDMI

Kev Tswj Xyuas Txhua - Nyob rau hauv - Ib lub khoos phis tawj, digital signage system, kev soj ntsuam Chaw Loj cov ntxaij, kev cob qhia cov khoom siv, siab - Daws Teeb Duab Testing Cov Khoom Siv

Qhov Zoo:

Qhov yooj yim system xaim hluav taws xob (audio thiab yees duab sib kis los ntawm ib Cable ib Cable) txhawb cov kev daws teeb meem siab - cov lus qhia txog kev daws teeb meem siab.

Ntsaws thiab ua si, zoo sib xws.

1. Kev Xaiv Xaiv

2. 1.environmental yam

Qhov kub thiab txias ntau: LVDs muaj ntau qhov dav dav - Kub ua tau.

Kev co kev cai: LVDS kev sib txuas yog cov txhim khu kev qha ntau dua.

EMC yuav tsum: LVDs muaj kev cuam tshuam muaj zog.

2. 2.System yuav tau

Kev daws teeb meem: HDMI yog nyiam rau cov ntawv thov siab dua.

Suab Yuav Tsum Tau Xaiv: HDMI yuav tsum tau xaiv thaum yuav tsum muaj audio-audio.

Scalability: HDMI yooj yim dua rau cov ntawv thov - Screen.

3. 3.Cost txiav txim siab

Cov nqi kev txhim kho: LVDs yuav tsum muaj kev tsim qauv ntau dua.

Cov khoom siv cov nqi: HDMI cables yog kim dua.

Tus nqi kho cov nqi: LvDDs yog ruaj khov thiab txhim khu kev qha.

1. Tag

LVDs thiab HDMI yog ob qhov tseem ceeb interface technologies rauMuaj LCD Zaub, Txhua tus nrog nws tus kheej qhov zoo thiab cov ntawv teev haum haum. LVDs tseem xav xaiv cov kev xaiv Harsh kev muaj teeb meem vim nws txoj kev ntseeg siab, thiab siv hluav taws xob muaj zog; HDMI, ntawm qhov kev sib tw, muaj cov txiaj ntsig tseeb hauv cov nqe lus ntawm cov kev daws teeb meem siab, audio - kev sib koom ua ke, thiab plert - thiab - Kev ua si ua haujlwm. Cov kws ua choj yuav tsum xav txog cov ntawv thov cov chaw ib puag ncig, cov kab ke yuav tsum tau, thiab muaj nqi rau kev xaiv thaum ua kev xaiv. Thaum tsim nyog, ib tug hybrid interface Soluth tuaj yeem tau txais los sib npaug nrog kev ua haujlwm thiab kev ntseeg tau.
