Tsav Txoj Kev Ntawm LCD Segment Code Screen
Oct 20, 2022| 1. Txoj kev tsav zoo li qub
Txoj kev tsav tsheb zoo li qub yog txoj hauv kev yooj yim tshaj plaws kom tau txais cov khoom zoo tshaj plaws, thiab nws yog qhov tsim nyog rau kev tsav tsheb ntawm cov cwj mem-qib kua siv lead ua cov khoom siv. Nyob rau hauv cov qauv electrode ntawm hom kua siv lead ua kua zaub ntaus ntawv, thaum muaj ntau tus lej sib xyaw ua ke, lub nraub qaum electrodes BP ntawm txhua qhov me me txuas ua ke. Nyob rau hauv lub voj voog ntawm txoj kev tsav tsheb zoo li qub, lub teeb liab mem tes ntawm lub oscillator yog siv ncaj qha mus rau sab nraum qab electrode BP ntawm cov kua siv lead ua kua zaub ntaus ntawv tom qab kev faib ntau zaus; thiab cov teeb liab mem tes ntawm ntu electrode yog tsim los ntawm kev sib txuas ntawm cov teeb liab xaiv cov teeb liab thiab lub sijhawm pulse.
Thaum ib yam khoom pixel raug xaiv rau cov zaub, lub pulse voltage theem sib txawv ntawm ob lub electrodes ntawm cov zaub pixel yog 1800, thiab ib tug 2V voltage mem tes ib theem yog generated ntawm lub pixel zaub, thiaj li hais tias cov zaub pixel. nthuav qhia cov yam ntxwv; Thaum ib yam khoom pixel tsis yog zaub Thaum xaiv, cov theem ntawm cov mem tes voltages ntawm ob lub electrodes ntawm cov duab pixel yog sib npaug, thiab qhov sib xyaw ua ke voltage mem tes ntawm cov duab pixel yog 0V, yog li paub txog cov khoom siv. Qhov no yog txoj kev tsav static. Txhawm rau txhim kho qhov sib piv, qhov voltage ntawm cov mem tes yuav raug kho kom haum.
Qhov zoo / qhov tsis zoo ntawm static drive:
Qhov kom zoo dua yog tias kev sib txuas ntawm LED cov khoom sib txuas yog yooj yim heev, thiab tag nrho cov LEDs tuaj yeem txuas nrog hauv cov kab nrog tsuas yog 5-6 kab, uas yooj yim rau kev debugging thiab txij nkawm. Cov zaub ci ci yog qhov zoo, thiab cov khoom siv tsav tsheb tsim nyog tuaj yeem siv los tsav LEDs hauv qab 2 meters, uas yog tsim los ua cov ntxaij vab tshaus sab nraum zoov loj.
Qhov tsis zoo yog tias txhua lub LED yuav tsum tau ua {{0}} tus tsav tsheb ICs, thiab cov khoom siv PCB yuav tsum tau ua. Lub zog noj yog me ntsis loj (5 npaug ntawm lub scan tsav). Tus nqi yog me ntsis siab dua (qhov nruab nrab tus nqi ntawm cov zaub tsav tsheb ib ntsis yog 0.4-1 yuan siab dua li ntawm tus tsav tsheb scan).
2. Dynamic tsav txoj kev
Qhov kom zoo dua yog tias cov zaub tsav tsheb yog qhov yooj yim, 2 ICs tuaj yeem tsav 8 LEDs hauv qab 10", thiab tus nqi qis dua. LEDs ntawm ntau qhov ntau thiab tsawg tuaj yeem txuas ncaj qha mus rau lub rooj tsav xwm loj, pawg tsav tsheb, thiab nthuav dav, txawm tias tsis muaj siv lub rooj tsavxwm PCB, kev siv hluav taws xob tsawg, lub sijhawm sib koom scanning zaub hom tau txais, thiab lub zog siv tsuas yog 1/5 ntawm cov zaub zoo li qub.
Qhov tsis zoo yog tias muaj ntau qhov sib txuas ntawm LED thiab cov tsav tsheb (tag nrho ntawm 8 ntxiv rau LEDs). Thaum tus lej lej loj, kev sib txuas thiab kev saib xyuas tsis yooj yim.
Qhov txawv ntawm ob:
Cov yam ntxwv ntawm kev tsav tsheb zoo li qub yog qhov sib txawv siab, siab ci, thiab cov lus teb ceev ceev. Cov yam ntxwv ntawm kev tsav tsheb dynamic yog tias kev tsav tsheb ntawm txhua qhov khoom me me yog staggered thiab tsav nyob rau hauv ib ntus los ntawm kev faib sijhawm, thiab tib lub caij tsav tsheb tuaj yeem siv tau!
