1. Dot-matrix LCD cov ntxaij vab tshaus yog arrays teem raws li cov cai. Graphic dot-matrix LCD modules muaj ntau. Lub dot matrix LCD npo yog tsim los ntawm ntau cov duab dots (sib npaug rau ib pixel ntawm cov zaub). Piv txwv li, 12864 dot matrix LCD npo muaj 128 dots kab rov tav thiab 64 dots vertically, ua rau tag nrho ntawm 128 * 64 dots. Los ntawm kev tswj cov ntsiab lus no, koj tuaj yeem tso saib cov duab lossis cov ntawv koj xav pom, thiab koj tuaj yeem tso saib cov ntawv nyeem ntawm ntau lub teb chaws ntawm qhov xav tau, scroll nce thiab nqis, sab laug thiab sab xis ntawm qhov screen, animation functions, thiab lwm yam. Qhov zoo ntawm dot matrix npo: txheeb ze rau ntu cov duab npo tuaj yeem ua ke ntawm qhov xav tau, tso saib cov ntsiab lus tuaj yeem nplua nuj dua, thiab cov duab qis-pixel kuj tsis du.
2. Segment LCD tseem hu ua cwj mem-segment LCD. Segment LCD yog hais txog ib qho LCD uas tuaj yeem tso saib lossis tsis tso cov ntawv tas li lossis cov duab kos ntawm qhov chaw ruaj khov ntawm lub vijtsam. Nws tsuas yog siv tau rau cov cim yooj yim thiab cov lej. Zaub, vim hais tias lub hwj chim noj tsawg heev, nws yog siv los hloov lub LED digital raj (muaj 7 cwj mem, siv los tso saib tus naj npawb 0 ~ 9), xws li lub laij lej, hluav taws xob moos, cua txias chaw taws teeb tswj, thiab lwm yam. , cov ntsiab lus tso saib yog txhua tus lej, kuj yooj yim dua. Qhov zoo ntawm ntu ntu code npo: kuj pheej yig dua li dot matrix npo, cov duab yog smoother.
