Tom qab cov kua siv lead ua kuazaub screenyog polarized, cov kua siv lead ua kua molecules yuav poob ib ntus ntawm cov yam ntxwv kho qhov muag. Nyob rau hauv ib txwm tsav tsheb zoo voltage thiab tsis zoo voltage, lub deflection lub kaum sab xis ntawm cov kua siv lead ua kua molecules ntawm tib pixel yog inconsistent, uas ua rau tib pixel nyob rau hauv lub yav dhau los thav duab (zoo voltage) Nws yog inconsistent nrog lub brightness tshwm nyob rau hauv lub tom ntej no ncej ( negative voltage).
Liquid crystal polarization txoj kev txhim kho:
1.In FPC tsim, siv 2.2uF, 25V rau lub capacitors ntawm VGH, VGH 1, thiab VGH 2 pins kom lub sij hawm tawm thiab txo qhov kev pheej hmoo ntawm cov seem seem;
2.Lub hwj chim-tawm ib ntus ntawm lub fixture thiab lub ntsiab board ntawm tag nrho cov tshuab raws li IC fais fab tuag specification;
(Saib rau IC specifications rau txawv qauv)
3.Power off sequence Spec: AVEE(VSN)->AVDD(VSP)->VDDI(IOVCC);
4.Power off sequence Spec: VCI-> IOVCC
3. Lub roj teeb ntawm lub xov tooj ntawm tes txais yuav lub roj teeb uas tsis tuaj yeem tshem tau los tiv thaiv lub zog tsis zoo ntawm lub tshuab tag nrho;
4. FPC tooj liab to yog nyob rau hauv tag nrho kev sib cuag nrog lub motherboard GND;
. Nco ntsoov xyuas tag nrho cov kev ua los ntawm kev tsim mus rau kev tshuaj ntsuam tawm (nrog rau ncaj qha rub tawm USB cable thaum lub cuab yeej tsis tau qhib)
Lub high voltage peb xav tau yog powered tawm ua ntej, thiab ces powered tawm tom qab uas tsis muaj voltage;
Disen Electronics Co., Ltd.yog ib qho kev sau los ntawm kev tshawb fawb thiab kev tsim kho, tsim, tsim, muag, muag thiab kev pabcuam raws li ib qho ntawm cov tuam txhab high-tech, tshwj xeeb hauv kev lag luam, tsheb zaub, kov npo thiab kho qhov muag lamination khoom R & D thiab kev tsim khoom, cov khoom siv dav siv hauv kev kho mob. Cov cuab yeej siv, cov khoom siv tes ua lag luam, Internet ntawm Tej yam terminals, thiab lub tsev ntse.Peb muaj kev nplua nuj R & D thiab kev tsim khoom hauvTFT LCD, kev lag luam, tsheb zaub, kov npo, thiab lamination tag nrho, thiab peb yog tus thawj coj hauv kev lag luam zaub.
