Xaiv txoj caiPCB (Printed Circuit Board)kom phim ibLCD (Crystal Display)suav nrog ntau qhov kev txiav txim siab tseem ceeb los xyuas kom muaj kev sib raug zoo thiab kev ua haujlwm zoo. Ntawm no yog ib daim ntawv qhia step-by-step los pab koj los ntawm cov txheej txheem:
1. Nkag siab koj lub LCD cov lus qhia
• Hom Interface: Txiav txim seb hom kev sib cuam tshuam koj lub LCD siv, xws li LVDS (Low-Voltage Differential Signaling), RGB (Liab, Ntsuab, Xiav), HDMI, lossis lwm yam. Xyuas kom PCB tuaj yeem txhawb nqa qhov kev sib tshuam no.
• Kev daws teeb meem thiab Loj: Txheeb xyuas qhov kev daws teeb meem (xws li 1920x1080) thiab lub cev loj ntawm LCD. PCB yuav tsum tau tsim los tswj cov kev daws teeb meem tshwj xeeb thiab kev teeb tsa pixel.
• Voltage thiab Fais fab Requirements: Paub meej tias qhov voltage thiab hwj chim yuav tsum tau rau lubLCD vaj huam sib luagthiab backlight. PCB yuav tsum muaj cov khoom siv hluav taws xob tsim nyog kom haum rau cov kev xav tau no.
2. Xaiv txoj cai Controller IC
• Compatibility: Xyuas kom lub PCB muaj xws li ib tug maub los IC uas yog sib xws nrog koj LCD cov specifications. Tus maub los IC yuav tsum muaj peev xwm tswj tau lub LCD qhov kev daws teeb meem, refresh npaum li cas, thiab interface.
• Nta: Xav txog cov yam ntxwv ntxiv uas koj xav tau, xws li kev ntsuas ua ke, kev ua haujlwm ntawm lub vijtsam (OSD), lossis cov yam ntxwv tshwj xeeb ntawm kev tswj xim.
3. Txheeb xyuas PCB Layout
• Connector Compatibility: Xyuas kom lub PCB muaj qhov tseeb connectors rau lub LCD vaj huam sib luag. Xyuas kom tseeb tias cov pinout thiab connector hom phim lub LCD interface.
• Teeb liab Routing: Paub meej tias PCB layout txhawb cov teeb liab routing rau LCD cov ntaub ntawv thiab cov kab tswj. Qhov no suav nrog kev tshuaj xyuas kab dav dav thiab kev taug kev los tiv thaiv teeb meem kev ncaj ncees.
4.Review Fais Fab Tswj Xyuas
• Kev Tsim Khoom Siv Hluav Taws Xob: Ua kom lub PCB suav nrog cov kev tswj xyuas hluav taws xob tsim nyog los muab cov hluav taws xob tsim nyog rau ob qho tib si.LCDthiab nws backlight.
• Kev Tswj Teeb Meem: Yog tias lub LCD siv lub teeb rov qab, xyuas tias PCB muaj cov kab hluav taws xob tsim nyog rau kev tswj lub teeb ci thiab lub zog.
5.Xav txog tej yam Environmental
• Kev Kub Kub: Xyuas kom PCB tuaj yeem ua haujlwm nyob rau hauv qhov kub thiab txias uas yuav tsum tau ua rau koj daim ntawv thov, tshwj xeeb tshaj yog tias nws yuav siv rau hauv qhov chaw hnyav.
• Durability: Yog hais tias lub LCD yuav siv nyob rau hauv rugged tej yam kev mob, xyuas kom meej lub PCB yog tsim los tiv thaiv lub cev kev nyuaj siab, kev co, thiab tej zaum yuav raug rau cov khoom.
6.Saib cov ntaub ntawv thiab kev txhawb nqa
• Cov ntaub ntawv thiab Phau Ntawv Qhia: Tshuaj xyuas cov ntaub ntawv thiab phau ntawv qhia rau ob qho tib si LCD thiab PCB. Xyuas kom lawv muab cov ntaub ntawv tsim nyog rau kev sib koom ua ke thiab kev daws teeb meem.
• Kev Pabcuam Kev Pabcuam: Xav txog qhov muaj kev txhawb nqa los ntawm PCB cov chaw tsim khoom lossis tus neeg muag khoom yog tias koj ntsib teeb meem thaum koom ua ke.
7.Prototype thiab Test
• Tsim Ib Tus Qauv: Ua ntej cog lus rau qhov kawg tsim, tsim ib qho qauv los sim kev sib koom ua ke ntawm LCD nrog PCB. Qhov no pab txheeb xyuas thiab daws cov teeb meem uas yuav tshwm sim.
• Ntsuam xyuas kom meej: Tshawb xyuas cov teeb meem xws litso saibartifacts, xim raug, thiab tag nrho kev ua tau zoo. Xyuas kom lub PCB thiab LCD ua hauj lwm ua ke seamlessly.
Piv txwv txheej txheem:
1.Xaiv lub LCD's Interface: Piv txwv tias koj lub LCD siv LVDS interface nrog 1920x1080 daws teeb meem.
2.Xaiv lub Rooj Tswjhwm Saib Tau Zoo: Xaiv aPCBnrog LVDS maub los IC uas txhawb nqa 1920x1080 daws teeb meem thiab suav nrog cov khoom sib txuas tsim nyog.
3. Txheeb xyuas cov kev xav tau ntawm lub zog: Tshawb xyuas PCB lub zog hluav taws xob kom ntseeg tau tias lawv phim lub LCD qhov hluav taws xob thiab cov kev xav tau tam sim no.
4. Tsim thiab Kev Ntsuas: Sib sau cov khoom sib txuas, txuas lub LCD rau PCB, thiab sim ua kom pom qhov ua tau zoo thiab ua haujlwm zoo.
Los ntawm kev ua tib zoo xav txog cov xwm txheej no, koj tuaj yeem xaiv aPCBuas phim koj LCD cov kev xav tau thiab ua kom ntseeg tau thiab ua tau zoo ntawm cov zaub.
DISEN Electronics Co., Ltd.tsim nyob rau hauv 2020, nws yog ib tug kws LCD zaub, kov vaj huam sib luag thiab zaub kov integrate kev daws teeb meem chaw tsim tshuaj paus uas tshwj xeeb nyob rau hauv R & D, manufacturing thiab marketing txuj thiab customized LCD thiab kov cov khoom.
