LCM muab cov neeg siv nrog tus qauv LCD zaub tsav tsheb interface (4-ntsis, 8-ntsis, VGA thiab lwm yam sib txawv). Cov neeg siv ua haujlwm raws li qhov xav tau ntawm kev sib txuas los tswj lub LCD kom pom tseeb. Piv nrog rau iav, LCM yog ib qho khoom siv LCD ntau dua. Rau me me - loj LCD zaub, LCM tuaj yeem txuas tau yooj yim rau ntau lub microcontrollers (xws li ib qho -chip microcomputers); Txawm li cas los xij, rau qhov loj - qhov loj lossis xim LCD zaub, nws feem ntau yog ib feem ntawm kev tswj hwm cov peev txheej lossis tsis tuaj yeem tswj tau tag nrho. Piv txwv li, 320 × 240 256- xim xim LCM qhia ntawm 20 teb / thib ob (uas yog, puv npo refresh zaub 20 zaug hauv 1 thib ob). Tus nqi ntawm cov ntaub ntawv xa hauv ib ob yog siab li: 320 × 240 × 8 × 20=11.71875Mb lossis 1.465MB. Yog tias tus qauv MCS-51 series ib leeg-chip microcomputer siv los ua cov txheej txheem, piv txwv tias cov lus qhia MOVX tau siv ntau zaus kom xa cov ntaub ntawv no tsis tu ncua, xav txog qhov chaw nyob hauv lub sijhawm suav, tsawg kawg yog 421.875MHz moos yuav tsum ua kom tiav cov ntaub ntawv xa mus. Nws tuaj yeem pom tias cov ntaub ntawv ua tiav ntau npaum li cas.
Qhov kev daws teeb meem ntawm fax kuj hu ua scanning ntom. Qhov siab dua qhov kev daws teeb meem, qhov tseeb scanning ntau dua. Nws tuaj yeem muab faib ua kev daws teeb meem ntsug thiab kab rov tav kev daws teeb meem. Vertical daws teeb meem yog hais txog tus naj npawb ntawm pixels tso tawm ib millimeter ntawm txoj kab ntsug kab rov tav, thiab kab rov tav kev daws teeb meem yog hais txog cov pixels tso tawm ib millimeter ntawm kab rov tav kab rov tav. Raws li cov qauv thoob ntiaj teb rau peb hom fax tshuab, kab rov tav kev daws teeb meem yog 8 pixels / mm, yog li qhov kev daws teeb meem ntawm lub tshuab fax feem ntau yog 8 pixels / mm × ntsug pixels / mm. Feem ntau, peb tshem tawm qhov kev daws teeb meem kab rov tav thiab tsuas yog qhia qhov kev daws teeb meem raws li kev daws teeb meem ntsug. Muaj peb hom kev daws teeb meem ntsug: tus qauv 3.85 pixels / hli, nplua 7.7 pixels / hli, thiab super nplua 15.4 pixels / hli.
