Dab tsi yog cov haujlwm ntawm TFT-LCD kua siv lead ua module?
Oct 19, 2022| Lub TFT-LCD kua siv lead ua kua module yog nruab nrog ib tug semiconductor hloov rau txhua pixel, thiab nws cov kev ua tau zoo ib yam li cov loj-scale integrated circuit. Vim tias txhua lub pixel tuaj yeem tswj tau ncaj qha los ntawm cov dot pulses, txhua qhov ntawm nws tus kheej muaj kev ywj pheej thiab tuaj yeem tswj tau tsis tu ncua, thiab txhua tus muaj cov haujlwm sib txawv. Tom ntej no, cia peb kawm txog cov haujlwm ntawm TFT-LCD kua siv lead ua module.
Cov haujlwm ntawm txhua feem ntawm TFT-LCD kua siv lead ua module tau piav qhia raws li hauv qab no:
1. Storage capacitor: lub peev xwm yog li ntawm 0.5pF, thiab nws cov ncej txuas nrog cov pob tshab kua siv lead ua electrode / pob tshab electrode, vim tias lub peev xwm ntawm cov kua siv lead ua kua electrode thiab pob tshab electrode yog hais txog { {3}}.1 pF. Qhov hluav taws xob tsis tuaj yeem tuav kom txog thaum lub vijtsam hloov tshiab tom ntej (piv txwv li, thaum lub sijhawm hloov tshiab yog 60 Hz, lub sijhawm tuav yog li 16ms), yog li kev saib xyuas yuav tsum tau ua nrog kev pab ntawm cov khoom ntim cia.
2. TFT: nyias zaj duab xis transistor, ib tug switching ntaus ntawv uas txiav txim seb cov kua siv lead ua kua yog them (lub nyias zaj duab xis transistor tsuas yog qhib los yog off. Cov kua siv lead ua kua thiab cov khoom ntim cia, thiab cov nqi them hluav taws xob yog txiav txim siab los ntawm LCD tsav Circuit Court).
3. iav hauv qab phaj: Nws yog siv rau kev sib cais.
4. Polarizing iav phaj: lub phaj polarizing, sab hauv polarizing iav phaj 1 yog kab rov tav qhib. Sab nrauv polarizing iav phaj 2 yog qhov qhib ntsug.
5. Lub pob tshab kua siv lead ua electrode txuas nrog lub hauv paus ntawm txhua nyias zaj duab xis transistor, thiab tsim ib lub charger electrode nrog cov pob tshab electrode. kom them cov kua siv lead ua kua hauv txhua pixel.
6. Xim lim: tseem hu ua xim lim, yog ib daim iav tsim los ntawm ntau cov transistors, LCD npo kua siv lead ua xim duab, qhov no feem ntau ua tiav los ntawm kev ntxiv cov xim lim ntawm cov pob tshab electrode thiab cov iav polarizing ntawm.
