Tus kheej hais lus, feem ntau lub vijtsam ntawm dot matrix kua tuaj yeem tso saib cov duab, suav cov cim thiab cov cim. Dab tsi tshwm sim tuaj yeem ua tiav los ntawm koj lub software thiab tuaj yeem hloov pauv. Lub screen code tawg tuaj yeem tso saib cov duab, cov cim Suav thiab cov cim, tab sis txoj haujlwm ntawm lub vijtsam tawg los tso saib cov duab thiab cov cim suav yog kho. Tsuas yog"8" los" meter" hloov tau. Raws li kev ua haujlwm tiag tiag ntawm Hangzhou Lihuang, saib cov yeeb yam tshwj xeeb?
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 Cov kab lus tawg LCD tseem hu ua tus cwj mem-sab LCD, uas yog hais txog lub vijtsam LCD ruaj khov uas qhia lossis tsis tso tawm ntawm txoj haujlwm. Nws tsuas yog siv tau rau cov duab yooj yim ntawm cov lej thiab cov cim. Nws yog tsuas yog siv los hloov LED cov raj (yog muaj 7 tus cwj mem ntu, siv los tso saib cov lej 0-9), xws li moos, landlines, tshuab xam zauv, thiab lwm yam. Cov ntsiab lus tso tawm yog txhua tus lej thiab nws yooj yim heev. Piv nrog rau ntu ntu, qhov sib txawv tseem ceeb ntawm dot matrix LCD npo yog tias Yin code LCD ntse qhia cov cim thiab cov lej, thaum lub dot matrix LCD npo tuaj yeem tso saib tsis tau tsuas yog cov lej tab sis kuj suav nrog cov cim thiab cov duab. Qhov tawg code LCD npo kuj tseem pheej yig dua hauv nqe. ntau ntau.
