Ib qho taw qhia yog ib lub cuab yeej uas qhia qee cov ntaub ntawv. Nws yog siv rau kev pom kev tswj ntawm qee yam xwm txheej, teeb liab, txheej txheem. Muaj ntau ntau hom kev ntsuas: hluav taws xob, khoom siv hluav taws xob, thiab lwm yam. Cov khoom siv hluav taws xob tau txais txiaj ntsig.

Tus ntsuas hluav taws xob yog lub cuab yeej uas tso cai rau koj los tso saib cov ntaub ntawv. Cov cuab yeej zoo li no tau nruab rau txhua yam khoom siv hauv tsev, hauv cov khoom siv hauv tsev, thiab lwm yam. Qhov taw qhia pab tus neeg teb xov tooj hauv kev tsim khoom lossis cov neeg nyob hauv tsev, hauv lub tsheb, nrawm, thiab qhov tseem ceeb tshaj plaws, pom qhov ntsuas qhov xav tau (piv txwv li, lub roj teeb qhia), tshwj xeeb tshaj yog cov uas nws tsis tuaj yeem txiav txim siab nrog nws lub siab. Nyob rau hauv rooj plaub uas yuav tsum tau muaj qhov tseeb ntawm kev ntsuam xyuas, cov ntsuas ntau tus lej raug siv, thiab thaum nws txaus los pom qhov tsis muaj lossis muaj lub teeb liab, cov ntsuas ntawm ib hom yog siv.

Muaj ntau yam kev xaiv. Ntxiv nrog rau cov cim tshwj xeeb, xws li tshuab hu xov tooj, hluav taws xob digital lossis matrix, cov khoom siv hluav taws xob hauv tsev feem ntau siv. Yog li, piv txwv li, lub teeb pom kev zoo lossis lub teeb ci semiconductor LED tuaj yeem ua haujlwm litso saib cov khoom hauv ceeb toom lossis cov tswj vaj huam sib luag.

Thiab qhov qhia tshwj xeeb matrix-hom ntsuas tuaj yeem siv rau cov hom phiaj hauv tsev, piv txwv li, los tsim cov ntawv tshaj tawm. Ntawd yog, nyob ntawm kev siv, ob lub teeb thiab lub diode, thiab cov hluav taws xob matrix tuaj yeem muaj lub hom phiaj dav dav. Nws lub npe yog qhov taw qhia. Qhov no tso cai rau peb kos cov lus xaus hauv qab no: qhov ntsuas tau txiav txim siab tsis yog ntau los ntawm nws lub hom phiaj thiab cov qauv tsim, tab sis los ntawm kev siv hauv ib lub cuab yeej lossis khoom siv.

Kev faib cov ntsuas ntsuas

1. Los ntawm kev teem caij - pab pawg thiab tus kheej.

2. Los ntawm imaging method:

- passive: kua siv lead ua kua, electrochromic, electrophoretic, ferro-ceramic;

- nquag: LED, cathodoluminescent, roj paug, incandescent.

3. Los ntawm qhov xwm txheej ntawm cov ntaub ntawv tso tawm:

- tus lej - qhia cov ntaub ntawv tus lej;

- ib leeg - qhia lub xeev nrog xim, ci;

- nplai - ua nyob rau hauv daim ntawv ntawm ob peb ib qho kev ntsuas, qhia txog qib lossis tus nqi ntawm tus nqi (piv txwv li, tus nqi ntsuas);

- mnemonic - hauv daim duab geometric lossis duab;

- alphanumeric - qhia cov ntaub ntawv hauv daim ntawv ntawm cov tsiaj ntawv, lej thiab cov cim;

- nraaj - xa cov ntaub ntawv cim thiab cov duab;

- ua ke - ua ke ob lossis ntau txoj kev xaiv.

4. Raws li tus tsim ntawm cov ntaub ntawv teb:

- Kev paub. Rau hom nosuav nrog lub tshuab nqus tsev, tso pa tawm, cov ntsuas hluav taws xob.

- Synthesizing signs. Cov no suav nrog matrix, ntu, xya ntu ntsuas.

5. Raws li lub peev xwm ntawm cov ntaub ntawv: ib zaug them thiab ntau tus nqi.

Roj teeb qhia
Roj teeb qhia

6. Raws li txoj kev imaging: dynamic (multiplex) thiab static.

7. Los ntawm xim: ib xim thiab puv xim.

8. Raws li txoj kev ntawm cov ntaub ntawv kis tau tus mob: analog thiab discrete.

Peb tau teev cov hom kev ntsuas tseem ceeb, tab sis muaj ntau qhov tsis sib xws (tag nrho qhov ntev, ci ntsa iab ntawm cov ntsiab lus, saib cov ces kaum, lub sijhawm teb, qhov hluav taws xob, thiab lwm yam) uas faib cov khoom siv rau hauv pawg.

Summarizing, cia peb hais tias qhov taw qhia yog ib qho khoom siv uas qhia txog qib, tus nqi ntawm ntau cov ntaub ntawv, xws li voltage, tam sim no, kub, roj teeb, thiab lwm yam. Cov ntsuas tau yooj yim heev rau kev ua haujlwm ntawm tus neeg nrog. ntau yam khoom siv, lawv txuag sijhawm, pab kom tsis txhob muaj xwm txheej ceev, thiab lwm yam.
