LCD Module: Cov Hom Pej Xeem (Common Parameters)

Cov yam ntxwv hluav taws xob:

Yuav kom pom cov ntsiab lus yuav tsum tau taws, qhov AC tsav hluav taws xob yuav tsum raug tso rau ntawm lub vas sab electrode ntawm lub LCD thiab cov hom electrode. Yuav kom paub meej cov zaub nyhuv thiab ua kom lub neej ua haujlwm ntawm cov kua siv lead ua kua, nws yog ib qho tsim nyog yuav tsum siv lub caij hloov siab tam sim no (AC) hloov qhov ncaj qha tam sim no (DC).

Tus LCD yuav ua tau zoo li qub lossis muaj zog. Lub pob zeb zoo li qub zoo sib xws, kev teeb tsa zoo, cov lus teb ceev ceev thiab kev tswj tau yooj yim. Txawm li cas los xij, vim txhua ntu nyias nyob nyias, cov electrodes loj loj. Yog li, kev tsav tsheb yog feem ntau yog siv.

LCD tsav waveforms tau piav nyob rau hauv peb txoj kev:

parameter

Piav qhia

LCD tsav hluav taws xob (VLCD)

Qhov kev tsav tsheb ntawm lub LCD yog qhov txawv ntawm lub voj voos hluav taws xob ntaw nruab rau lub lit feem thiab qhov feem ntau voltage (peak-to-peak)

Lub voj voog tub ceev xwm (Duty)

Yuav kom txo cov xov tooj ntawm cov electrodes ntawm lub LCD, siv ntau lub tsheb tsav, thiab qhov voltage ntawm LCD yog AC waveform. Lub Dudu ntawm lub LCD yog qhov sib piv ntawm qhov feem ntawm qhov pib qhov siab tshaj uas siab tshaj qhov pib qhov hluav taws xob hauv ib lub voj voog.

Kev Ntsig Siab (Kev Ntseeg)

Tus tsav lub dav hlau ntawm lub LCD yog li ntawm ntau theem. Yuav kom tiv thaiv qhov sib txawv ntawm qhov tsis sib haum, ib qho voltage yog siv rau cov electrode coj los siv rau cov uas tsis yog teeb pom kev pixel, uas tau txo qhov kev cuam tshuam ntawm kev cuam tshuam los ntawm lub teeb pom kev pixel thiab tiv thaiv qhov sib txawv ntawm kev tsis sib luag. tseem ceeb. Qhov piv ntawm cov nqi hluav taws xob tsis zoo ntawm qhov tsis pom kev hauv pixel (tsis yog cov raug xaiv) hauv LCD kom zoo npaum li cov teeb pom kev zoo ntawm lub teeb pom kev zoo pixel (qhov taw tes xaiv) qhov siab (1 / n) yog hu ua kev sib haum siab.

Thaum twg yuav tsum muaj cov khoom siv dej ua kua, cov tsav tsheb nres, lub voj voog, thiab kev sib haum xeeb yuav tsum yog tus neeg tsav tsheb.

Cov yam ntxwv kub:

Cov khoom siv ua kua dej ua kom muaj kub dua thiab feem ntau muab cais ua ob hom: hom kub thiab dav hom kub. Qhov tshwj xeeb daim ntawv thov yog raws li nram no:

Hom kub ntau

Kev khiav hauj lwm kub

cia kub

Qhov kub thiab txias li cas

0 ° C - 50 ° C

-10 ° C - 60 ° C

Kub dav hom

-20 ° C - +70 ° C

-30 ° C - +80 ° C

Ntxiv mus, yog tias qhov chaw tshwj xeeb yuav tsum muaj ntau yam khoom siv ua kua, xws li cov khoom siv tub rog lossis kev tshawb fawb tshawb fawb, tshwj xeeb yuav tsum tau ua.

Ua hauj lwm foundations:

Qhov sib piv ntawm cov kua siv lead ua kua hloov nrog cov kev hloov ntawm qhov pom, uas yog lub siab tshaj plaws ntawm qhov kev taw qhia thiab qhov dav hlau ntawm cov kua siv lead ua kua. Yog hais tias cov nplaim ntawm cov kua siv lead ua kua tau pom tias yog lub ntsej muag moos, qhov pom lub kaum yuav muab faib ua plaub yam raws li tus neeg saib xyuas pom kev pom: 12:00, 3:00, 6:00, thiab 9 : 00, tab sis feem ntau yog siv yog 6 Point thiab 12 o'clock saib cov khoom muag.
