LCD teeb pom kev zoo

LCD teeb pom kev zoo

Thaum nws tawm mus rau qhov teeb meem ntawm qhov teeb meem, nws yog qhov tsim nyog kom faib cov kua siv lead ua kua los ntawm lwm lub kaum, uas yog, kev xa, kev xav, thiab cov hlab ntsha hloov hluav taws xob. Txij li cov kua siv lead ua kua yog ib qho kev pom lub teeb pom kev zoo-tso tawm, nws yog ib qho tseem ceeb kom muaj ib lub teeb ci sab nraud rau cov kua siv lead ua kom pom. Cov kua nplaum yuav kis tau zoo yuav tsum tau rov qab, cov kua pleev ua kom haum lub teeb pom kev zoo, thiab cov yeeb-yaj-kiab muaj zog yuav tsum muaj lub teeb ntom nti lossis teeb nruab nrig. Cov nraub qaum sab nraud yog lub teeb tawm ntawm lub teeb tawm (LED), electroluminescent (EL) thiab txias cathode fluorescent (CCFL / CCFT).

<1>. Ob lub luag haujlwm ntawm kev siv tshuab nrig yog:

1. Cov kua siv lead ua kua yuav siv tau los ntawm kev kuaj pom los yog tsis muaj lwm lub teeb;

2. Txhim kho qhov ci ci ntawm qhov teeb ci tom qab thiab txhim kho cov duab ntxig.

<>. Kev faib tawm:

Cov kev siv feem ntau yog siv raws li nram qab no:

1) LED backlight:

Tshwj xeeb feature

· Lub neej ntev,> 100,000 xuab moos;

· Kev hloov yooj yim ntawm kev ci ntsa iab;

· Nws yog ib txoj kev siv ntau tshaj li kev siv;

· Muaj plaub qhov sib txawv (qhia hauv qab) uas tsim nyog rau cov kev xav tau nruab hnub;

· Lwm hom kev teeb tsa tuaj yeem tsim los ntawm tus neeg muas zaub.

Lus Cim: "A" yuav tsum txuas nrog rau + 3.8V ~ + 4.2V, tsis yog txuas ncaj qha mus rau + 5V, vim qhov teeb meem nram qab no ntev

> 4.2V yuav ua rau nws ntxeev siab, uas yuav cuam tshuam rau cov zaub tsis zoo. Lub sijhawm no, koj yuav tsum nqis tes rau koj txoj kev kho mob + 5V.

2) EL-electroluminescence

Tshwj xeeb feature

· Muaj lub teeb ci ntsa iab thiab teeb pom kev zoo;

· Backlight board yog nyias nyias, feem ntau tsawg dua 1 hli, yog li nws muaj me ntsis ntxim rau cov thickness ntawm tag nrho LCM;

· Pib thaum pib ci ntsa iab siab hauv kev tsav tsheb, thiab ib nrab ntawm nws txoj kev ci ci yog 5,000-8,000 teev;

· Ntau hom xim, feem ntau yog siv dawb, xiav ntsuab, daj;

· EL backlight xav tau tshwj xeeb inverter zog mov, nws qhov input voltage 5V, cov zis yog 90-110V,

AC voltage ntawm 400-600HZ.

3) CCFL-Txias Cathode Fluorescent Teeb

Tshwj xeeb feature

· High brightness thiab qis zog siv;

· Tsim kom muaj qhov nraub qaum tsim nyog rau qhov chaw saib loj;

· Kev tu tsiaj xim zoo nkauj heev;

· Brightness adjustable;

· Qhov nruab nrab qis nruab nrab ib nrab yog 20,000 xuab moos;

· Yuav tsum muaj tus qauv inverter.
