Kev hem ntawm hluav taws xob zoo li qub rau LCD saib
Peb tau txais cov lus nug los ntawm qee cov neeg siv khoom txog cov teeb meem saum toj no, thiab tau sau cov ntsiab lus hauv qab no:
Cov lus teb rau cov lus nug saum toj no yog qhov tseeb: nws muaj kev cuam tshuam kiag li!
Ntawm no yog ib qho kev piav qhia txog kev phom sij thiab kev tiv thaiv hluav taws xob zoo li qub rau cov khoom siv hluav taws xob:
Kev phom sij:
① Cov hluav taws xob zoo li qub nyiam cov plua plav, hloov cov impedance ntawm circuits, cuam tshuam cov khoom lag luam thiab kev ua neej.
② Cov teb hluav taws xob lossis cov dej ntws tuaj yeem ua rau cov rwb thaiv tsev lossis cov khoom siv hluav taws xob puas tsuaj, ua rau lawv ua haujlwm tsis tau (ua kom puas tsuaj tag nrho).
③ Thaum tshav kub kub tsim los ntawm hluav taws xob tam sim no lossis cov dej ntws tuaj yeem ua rau cov khoom puas tsuaj, ua rau lawv ua haujlwm ntxiv, tab sis ua rau lawv lub neej luv.
Kev tiv thaiv:
1. Kev tiv thaiv hluav taws xob zoo li qub ntawm qhov chaw ua haujlwm. Static- cov khoom siv rhiab heev yuav tsum tau ua haujlwm hauv qhov chaw ua haujlwm tiv thaiv- zoo li qub.
2. Kev tiv thaiv hluav taws xob zoo rau cov neeg ua haujlwm. Cov neeg ua haujlwm yuav tsum hnav cov khaub ncaws ua haujlwm zoo li qub, cov hnab looj tes, tiv thaiv- khau ua haujlwm zoo li qub, tiv thaiv- lub kaus mom zoo li qub, lub dab teg, thiab pob taws.
3. Kev tiv thaiv hluav taws xob zoo li qub thaum khaws cia thiab kev thauj mus los. Static- cov khoom siv rhiab heev yuav tsum tsis txhob muab khaws cia lossis thauj thaum nyob hauv lub xeev them nyiaj.
Txhawm rau ua tiav cov haujlwm saum toj no, txoj hauv kev yooj yim yog kom txo qhov voltage ntawm cov khoom raug them mus rau hauv tus qauv tsim - xav tau tus nqi nyab xeeb. Qhov no xav kom tus nqi (Q) thiab tsis kam (R) hauv cov qauv hauv qab no me me, thiab cov electrostatic capacitance (C) loj.
