Pixel zaub tswj

Tib yam kab ntawm txoj kab npoo kab rov tav ntawm TFT yog txuas nrog ua ke, ib kab, ib kab, muaj ntau txoj kab, muaj ntau txoj kab tswj, hu ua GATE kawg.

Hom GATE: qhib rau kab, qhib tsuas muaj kab ib zaug.

Tib sab ntawm longitudinal TFT ntws (DATA) txuas ua ke, kab, kab, ntau npaum li cas muaj ntau cov ntaub ntawv (teeb liab), hu ua SOURCE kawg. Tus SOURCE xaus rau ntawm txhua kab ntawv. Txhua qhov TFT ntawm lub npoo txuas nrog lub pixel electrode (teeb liab electrode), lwm qhov electrode ntawm tag nrho cov pixels, txawm ua ke, hu ua cov electrode COM, ua sab hauv ntawm lub iav, vim lub peev xwm tsim los ntawm cov pixel electrode me me, ces tus nqi yuav muab cia rau hauv me me, tsis muaj peev xwm kov tsis tau vim hais tias hluav taws xob los ntawm lub qhov poob tawm, qhov cuam tshuam rau lub sij hawm cia cov duab, yog li tsim, ntxiv ib daim card capacitor thiab pixel electrode.
