1. Dot matrix LCD cov ntxaij vab tshaus yog teem raws li ib qho kev txiav txim thiab cov cai. Feem ntau, muaj graphic dot matrix LCD modules. Muaj ntau lub ntsiab lus hauv nws. Los ntawm kev tswj cov ntsiab lus no, cov ntawv nyeem lossis cov duab tuaj yeem tso tawm, thiab lub vijtsam tuaj yeem txav tau nce thiab nqis, sab laug thiab sab xis, thiab cov haujlwm animation tuaj yeem ua tiav. Piv txwv li, 12864 dot matrix LCD npo muaj 64 ntsug dots thiab 128 kab rov tav dots. Muaj tag nrho ntawm 128 * 64 dots.
⒉ Lub vijtsam LCD tawg kuj tseem hu ua cwj mem-seg LCD, uas yog hais txog lub vijtsam LCD ruaj khov uas qhia lossis tsis tso tawm ntawm txoj haujlwm.

Cov ntsiab lus tso tawm yog txhua tus lej thiab nws yooj yim heev. Piv nrog rau ntu code, qhov sib txawv tseem ceeb ntawm dot matrix LCD npo yog tias ntu code LCD ntse qhia cov cim thiab cov lej, thaum lub dot matrix LCD npo tsis tuaj yeem tso saib cov lej xwb tab sis kuj tso saib cov cim thiab cov duab. Qhov tawg code LCD npo kuj tseem pheej yig dua hauv nqe. ntau ntau. Raws li pom hauv daim duab hauv qab no, koj tuaj yeem pom
