Lub hauv paus ntsiab lus ntawm segmented LCD yog dab tsi? COM thiab SEG kab sawv cev li cas?

Qhov tseeb, kev sib raug zoo ntawm kev tsav tsheb waveforms thiab kua siv lead ua kua yog qhov yooj yim heev. Tsuas yog nco ntsoov tias cov kua siv lead ua kua tsis tuaj yeem ntxiv qhov ncaj qha tam sim no. Tag nrho cov waveforms yog siv los tsim AC tsav voltage teeb liab. Txawm hais tias cov waveforms ntawm COM thiab SEG zoo li nyuaj, lawv ua tau yooj yim heev. COM yog ib ntus. Lub scanning pulse sequence tshwm dua thiab dua. Txawm hais tias nws tuaj yeem teeb lossis tsis yog nyob ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm COM thiab SEG waveforms.

Piv txwv li, 3V 1/2bias tsav nti COM thiab SEG yuav teeb cov kua siv lead ua kua tsuas yog thaum COM yog 3V thiab SEG yog 0V lossis thaum COM yog 0V thiab SEG yog 3V, thiab nws yuav tsis teeb nyob rau hauv lwm yam xwm txheej.

Bias yog hais txog qhov sib txawv coefficient ntawm cov kua siv lead ua kua. Cias muab, nws qhia tus naj npawb ntawm cov kauj ruam ntawm kev tsav tsheb voltage. 3v 1/2bias muaj peb qhov voltages: 3v 1.5v 0v. 3v 1/3bias muaj plaub qhov voltages: 3v 2v 1v 0v, tab sis lawv yog tag nrho 3v kua siv lead ua blocks. Teeb tsa, tam sim no koj paub dab tsi 1/2bias thiab 1/3bias tuaj yeem suav. Qhov loj dua tus lej tsis zoo, qhov pom tseeb qhov txawv ntawm lub teeb thiab tsis yog lub teeb, uas txhim kho qhov sib piv ntawm lub teeb thiab tawm.

Tsis muaj cov ntaub ntawv tshwj xeeb hauv cheeb tsam no. Qhov tseeb, nyeem cov lus qhia tshwj xeeb ntawm LCD tsav tsheb chips yog txoj kev ceev tshaj plaws.
