Segment code LCD lossis ntu code LCD npo tsuas yog ib txoj hauv kev rau cov neeg siv ntawm cov ntxaij vab tshaus LCD hu rau qee hom LCD npo, tab sis hauv kev lag luam LCD, nws feem ntau hu ua qauv LCD npo kom paub qhov txawv ntawm qhov taw tes. Array LCD npo, yog li ntu LCD npo tsis yog ib qho kev qhia nruj heev lossis kev faib tawm. Lub npe ntu ntawm cov kua siv lead ua kua siv lead ua los ntawm cov ntawv thov thaum ntxov ntawm lub vijtsam LCD, feem ntau yog siv los hloov LED cov raj (nws yog tsim los ntawm 7 ntu ntu, siv los tso saib tus lej 0 ~ 9), xws li kev suav Yeej, cov ntsiab lus tso tawm ntawm cov khoom siv, moos thiab watches, thiab lwm yam yog cov lej thiab kuj yooj yim. Niaj hnub no, cov ntxaij vab tshaus LCD uas tsis yog-dot-matrix feem ntau yog hu ua ntu LCD cov ntxaij vab tshaus.
Kev faib tawm
LCD muab faib ua hom: TN hom LCD, HTN hom LCD, STN hom LCD, FSTN hom LCD thiab ntau lwm yam, kuj ua raws li cov pixels ntawm dot matrix LCD npo, thiab cov pixels ntawm ntu LCD npo. Nws yog dawb nyob rau hauv kev npaj thiab tsos. Qhov feem ntau zoo ib yam li"8" teb ntawm ib lub raj digital. Ib"8" yog tsim los ntawm 7 strokes, uas yog, 7 pixels. Lub" 8" hauv"M" font yog tsim los ntawm 16 pixels. Ntawm chav kawm, tus cwj mem ntu ntawm ntu LCD npo tuaj yeem ua rau txhua yam, tsuav yog lub peev xwm tsav tsheb ntawm cov tsav nti tso cai. Piv txwv li: lub tuam txhab' lub logo, lwm yam qauv, ntawv nyeem, thiab lwm yam.
Tus nqi tsim khoom ntawm cov khoom siv lead ua kua yog qhov tsawg. Tus nqi tsav tsheb ntawm ntu LCD kuj tsawg heev, thiab ntau dua classic HT1621 series nti yog qhov kev xaiv zoo. HT1621 tuaj yeem tsav 32x4=128 strokes, uas yog sib npaug rau 16" 8" cov cim. Lub interface ntawm HT1621 yog serial, nrog CS,
WR, RD (RD kuj siv tau), DATA ob peb pins. HT1621 tseem tuaj yeem tsav lub buzzer, uas tuaj yeem tawm suab nrog lub siab thiab qis.
txoj cai ua haujlwm
TN-hom LCD cov ntxaij vab tshaus feem ntau muaj peb hom: kev sib kis tag nrho, ib nrab kis, thiab kev xav. Cov kua siv lead ua kua yuav tsis nquag tawm lub teeb, thiab nws yuav tsum tau muab tso rau sab nraud nrog lub teeb ci. Lub teeb ci ntawm lub pob tshab kua siv lead ua los ntawm qab cov kua siv lead ua kua; lub teeb pom kev ntawm cov kua siv lead ua kua los ntawm lub hauv ntej ntawm cov kua siv lead ua kua, uas yog pom los ntawm cov polarizer ntawm cov kua siv lead ua kua screen, thiab tom qab ntawd mus txog cov neeg soj ntsuam' lub qhov muag; lub semi-transmissive kua siv lead ua yog nyob nruab nrab ntawm ob Nyob rau hauv lub meantime, muaj ob lub teeb los ntawm qab cov kua siv lead ua kua thiab reflected lub teeb ntawm pem hauv ntej. Yog li ntawd, lub pob tshab kua siv lead ua yuav tsum tau siv lub backlight, lub reflective kua siv lead ua tsis xav tau kev siv lub backlight, thiab semi-transmissive kua siv lead ua yuav siv ib tug backlight los yog tsis. Nws yog tsis yooj yim sua los soj ntsuam cov zaub nyob rau hauv qhov tsaus ntuj ntawm ib tug LCD npo uas tsis siv lub backlight.
Segment LCD muaj ob peb yam tseem ceeb xws li tus nqi qis, tus nqi tsav qis, kev ua haujlwm yooj yim, dawb hom, thiab lwm yam, yog li nws kuj tau siv dav. Xws li cov teb hauv qab no: * Cov cuab yeej, ntsuas: roj ntsuas, ntsuas dej, tsheb npav, suav cov roj xa hluav taws xob-* Cov khoom siv hauv chaw ua haujlwm: fax tshuab, punch phaib, lub sijhawm tuaj koom. Cov khoom siv tswj kev nkag-* Cov khoom siv sib txuas lus: ntau daim npav IC Xov Tooj, Xov Tooj Hauv Xov Tooj, Xov Tooj Hauv Xov Tooj, IP xov tooj - * Cov txhab nyiaj hauv tuam txhab: POs tshuab - * Kev them se: lub tshuab tswj se ★ cov khoom siv kho mob: lub cev saib xyuas thiab ntau yam khoom siv kho mob - * Cov cuab yeej tswj kev lag luam : Tsis siv neeg tswj - - * Ntau yam txiv neej-tshuab interfaces, Handheld li, thiab lwm yam.
