1. Ua kom pom lub kaum sab xis dav ntawm cov cuab yeej hluav taws xob tsheb
Lub dot matrix LCD kua siv lead ua zaub ua ke nrog AD hloov dua siab tshiab thev naus laus zis thiab ib leeg-chip thev naus laus zis tuaj yeem siv rau kev tswj hwm ntawm ntau yam khoom siv sib txawv. Piv txwv li, cov twj paj nruag tsheb, cov cuab yeej hluav taws xob tsheb, cov cuab yeej maus taus, thiab lwm yam. Qhov no yog vim lub dot matrix LCD kua siv lead ua zaub tuaj yeem ua kom pom lub kaum sab xis dav ntawm cov cuab yeej hluav taws xob tsheb, kom cov neeg siv muaj lub kaum sab xis saib zoo dua los saib xyuas qhov chaw nyob ib puag ncig. .
2. Txhim kho qhov sib piv dub thiab dawb ntawm cov ntsuas hluav taws xob tsheb
Lub dot-matrix LCD kua siv lead ua kua zaub tau ua lub luag haujlwm loj hauv kev tsim thiab ua cov ntsuas tsheb hluav taws xob, vim tias nws zoo heev txhim kho qhov sib piv dub thiab dawb ntawm hluav taws xob tsheb meters. Vim tias cov dot matrix LCD tuaj yeem teeb tsa nrog cov qauv sib txawv thiab qhov sib txawv, cov neeg siv tuaj yeem paub qhov txawv ntawm cov ntsiab lus pom los ntawm cov meters sib txawv txawm nyob hauv qhov tsaus ntuj.
3. Txhim kho cov xim nplua nuj ntawm hluav taws xob tsheb ntsuas
Lub dot-matrix LCD kua siv lead ua zaub nws tus kheej tsis muaj xim, tab sis nws tuaj yeem tso cov xim sib txawv thiab cov ntsiab lus los ntawm ib qho kev pab cuam ib leeg. Qhov sib txawv ntawm cov khoom siv hluav taws xob ntawm qee lub tsheb hluav taws xob tau tso tawm los ntawm kev teeb tsa ntawm ib lub tshuab hluav taws xob microcomputer, uas yog qhov tsim nyog rau kev txhim kho cov nplua nuj ntawm cov xim ntau dua li lwm hom ntawm cov ntxaij vab tshaus.
