Nrog rau kev tsim kho tshiab ntawm kev siv thev naus laus zis, ntau thiab ntau cov khoom siv hluav taws xob tau paub rau txhua tus, thiab tib neeg muaj kev vam khom rau cov khoom siv hluav taws xob ntau dua. Niaj hnub no, kev tshaj tawm tau nkag mus rau lub sijhawm tshiab ntawm digital thiab audio-visual, thiab tus yuam sij rau kev lag luam nce qib thiab kev nthuav dav ntawm kev lag luam kuj tseem raug kaw hauv "fifth tiam media" sab nraum zoov LCD advertising tshuab. Feem ntau, koj tuaj yeem ntsib qhov teeb meem tsis muaj suab nrov ntawm lub tshuab luam ntawv sab nraum zoov LCD? Yog li, koj yuav tsum ua li cas thaum lub tshuab luam ntawv sab nraum zoov LCD tsis muaj suab nrov?
1. Tshawb xyuas cov khoom siv
Qhib lub hau rov qab ntawm lub LCD advertising player, thiab siv lub multimeter los xyuas seb lub hwj chim amplifier ntawm lub rooj tsav xwm tsav tsheb puas muaj zog thiab zoo li qub? Yog hais tias lub hwj chim amplifier yog powered ntawm ib txwm, cov kauj ruam tom ntej yog los xyuas seb cov kab txuas ntawm tus neeg hais lus puas zoo li qub?
2. Hloov khoom siv
Yog hais tias lub hwj chim amplifier ntawm lub LCD advertising tshuab tsav tsheb yog txawv txav, hloov lub rooj tsav tsheb; yog tus hais lus txawv txav, hloov tus hais lus. Tsis tas li ntawd, yog tias qhov sib txuas ntawm cov neeg hais lus ntawm lub tshuab LCD tshaj tawm tsis ruaj khov, nws yog qhov yooj yim tshaj kom poob. Yog hais tias nws ntog, siv ib tug soldering hlau los solder nws zoo. Yog hais tias lub suab nrov ua suab nrov, nws txhais tau hais tias lub rooj tsav tsheb ntawm lub tshuab tshaj tawm raug puas tsuaj, thiab lub rooj tsav xwm tsav tsheb raug hloov tam sim ntawd.
