1. Kev teeb tsa
OLED installation feem ntau siv 3 txoj hauv kev:
1. Vim tias nws yog nyias nyias, feem ntau yog ob-sided daim kab xev los yog npuas daim kab xev yog glued rau PCB.
2. Yog tias qhov yuav tsum tau muaj kev nyab xeeb siab, koj tuaj yeem muab cov txheej txheem hlau nyob ib ncig ntawm lub vijtsam, thiab siv cov ncej hlau los nias OLED ntawm PCB. 3. Thaum ua cov qauv, tawm ntawm OLED daim npav qhov zoo.
Koj tuaj yeem tiv tauj peb lub tuam txhab rau kev tsim tshwj xeeb, ROHM LCD yuav muab cov neeg siv khoom tsim nyog.
2. Kev khoov ntawm FPC
FPC feem ntau tuaj yeem khoov tau, tab sis nws tsis tuaj yeem folded ntau dhau. Nws yog feem ntau ntsib cov neeg siv khoom uas tsim thawj zaug quav FPC ntawm lub kaum sab xis rau vuam lossis ntsaws, ua rau muaj kev sib cuag tsis zoo nrog FPC tom qab lub sijhawm, ua rau tsis muaj qhov tsis pom kev, thiab lwm yam, yog li thaum khoov- nco ntsoov xav txog qhov chaw seem.
Thaum pab cov neeg siv khoom hauv kev txhim kho, yuav muaj ntau yam teeb meem zoo sib xws. ROHM LCD tau tsim tshwj xeeb hauv kev tsim cov ntxaij vab tshaus LCD rau ntau xyoo, thiab yuav qhia cov neeg siv khoom ntawm cov ntsiab lus ntawm kev saib xyuas hauv txhua qhov kev nthuav dav kom ntseeg tau tias cov neeg siv khoom yuav tsis rov txhim kho rau cov teeb meem zoo sib xws.
3. Lub zog
OLED npo yuav tsum muaj ob qhov ua haujlwm voltage, VDD thiab VCC (los yog VPP). Ntawm lawv VDD yog qhov ua haujlwm voltage ntawm IC logic feem, feem ntau 2.8 ~ 3.3V.
vCC (los yog VPP) yog qhov hluav taws xob backlight zoo ib yam li LCD, siv los teeb tsa pixels.
Nyob rau hauv lub xeev kaw los yog standby lub xeev, nws yog tsim nyog los xyuas kom meej tias VCC (los yog VPP) yog 0, txwv tsis pub nws yuav tsim mA-level to tam sim no.
Tshwj xeeb, nws yuav tsum raug sau tseg tias thaum siv DCDC qauv zoo ib yam li daim duab hauv qab no kom tau txais VCC (lossis VPP)), CE davhlau ya nyob twg ntawm DCDC nti tsis tuaj yeem ua qhov tso tawm 0, thiab qhov kaw ntawm CE davhlau ya nyob twg tsuas yog tuaj yeem ua tau. ua cov zis VOUT=VIN. Lub hwj chim yuav tsum tau muab tua ua ntej VIN.
4. CROSSTALK
Txij li thaum lub passive OLED yog tsav los ntawm kab scanning voltage, thaum tus naj npawb ntawm pixels teeb los ntawm kab thiab kab kuj loj, qee kab yuav ci dua thiab qee kab yuav tsaus dua.
Muaj 2 txoj hauv kev los daws qhov teeb meem no:
1. Thaum tsim cov qauv, sim siv cov ntawv dawb ntawm cov keeb kwm yav dhau los dub, uas yuav pab tau zoo.
2. Yog tias koj xav siv nws tiag tiag, koj tuaj yeem sim txo qhov screen brightness (txo tus nqi ntawm lub brightness register) los kho qhov pom kev.
Rau cov ntxaij vab tshaus xim, CROSTALK feem ntau yuav tshwm sim vim muaj cov qauv nplua nuj. Lub hauv paus ntsiab lus tsim los kuj yog nyob ntawm qhov tsaus ntuj. Tshwj xeeb, nws yog cov nyhuv tso saib: tua tag nrho peb cov xim ntawm cov xim tom qab RGB> tua ob xim hauv RGB> tua ib qho xim hauv RGB.
5. Hlawv npo
Cov duab ntev ntev ntawm daim duab tas yuav ua rau cov duab khaws cia (tseem hu ua hlawv-hauv). Kev daws: Teeb lub vijtsam txuag kom cov ntsiab lus hloov pauv.
