PCB cov laug cam rau TFT LCDs yog cov ntawv luam tawm tshwj xeeb hauv hluav taws xob tsim los cuam tshuam thiab tswj hwmTFT (nyias-zaj duab xis transistor) lcd qhiaCov. Cov rooj tsavxwm no feem ntau los tswj cov zaub ua haujlwm thiab ua kom muaj kev sib txuas lus zoo ntawm LCD thiab cov seem ntawm cov kab ke. Ntawm no yog ib tug txheej txheem cej luam ntawm cov hom PCB cov laug cam feem ntau siv nrog TFT LCDs:
1. LCD Cov Chaw Tswj Xyuas
•Lub hom phiaj:Cov rooj tsavxwm tswj lub interface ntawm TFT LCD thiab cov chav ua haujlwm tseem ceeb ntawm lub cuab yeej. Lawv coj kev hloov pauv hloov dua siab tshiab, kev tswj lub sijhawm ntev, thiab kev tswj hwm hwj chim.
•Nta:
•Maub los ICS:Kev sib xyaw ua ke cov txheej txheem uas cov txheej txheem video teeb tsa thiab tswj cov zaub.
•Connectors:Ports rau txuas rau LCD Vaj Huam Sib Luag (piv txwv li, LVDs, RGB) thiab cov cuab yeej tseem ceeb (piv txwv li HDMI, VGA).
•Lub zog hluav taws xob:Muab lub zog tsim nyog rau ob qho tib si ntawm cov zaub thiab nws cov backlight.
2. Tsav tsheb txiag
• Lub Hom Phiaj:Cov tsav tsheb tswj hwm cov haujlwm ntawm TFT LCD ntawm qib ntxiv, tsom mus rau tsav tus neeg lub pixels thiab tswj hwm cov zaub ua haujlwm.
•Nta:
• Tus tsav ICS:Cov cim tshwj xeeb uas tsav lub pixels ntawm tft zaub thiab tswj hwm tus nqi tshiab.
•Interface sib haum:Cov laug cam tsim los ua haujlwm nrog kev mob ntsws tshwj xeeb LCD panels thiab lawv cov paib cim cov paib.
3. Interface cov laug cam
• Lub Hom Phiaj:Cov rooj tsav xwm no pab txhawb kev sib txuas ntawm TFT LCD thiab lwm cov kev ua haujlwm, hloov cov cim thiab cov kev qhia sib txawv ntawm cov sib txawv.
•Nta:
•Teeb Liab Hloov Dua:Cov cim hloov ntsiab lus ntawm cov qauv sib txawv (piv txwv li, LVDs rau RGB).
•Hom Txuas:Nrog rau ntau txuas txuas kom phim rau ob qho tib si TFT LCD thiab cov txheej txheem tso zis kev cuam tshuam.
4. BacklLiver tsav tsheb
•Lub hom phiaj:Mob siab rau kev faib tawm thiab tswj lub backlight ntawm traft lcd, uas yog qhov tseem ceeb rau kev pom pom.
•Nta:
•Backlight Tswj ICS:Tswj lub ci ci thiab lub zog ntawm lub backlight.
•Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob:Muab cov voltage uas yuav tsum tau thiab tam sim no rau lub backlight.
5. Kev Cai PULBs
•Lub hom phiaj:Kev tsim qauv qauv PCBs raug txiav rau TFT cov ntawv thov TFT, feem ntau yuav tsum muaj rau cov cim tshwj xeeb lossis tshwj xeeb.
•Nta:
•Ua qauv tsim:Cov txheej txheem kev cai thiab Circuital kom tau raws li kev xav tau ntawm TFT LCD thiab nws daim ntawv thov.
•Kev sib xyaw:Tuaj yeem sib txuas tus maub los, cov neeg tsav tsheb, thiab kev tswj hwm lub zog rau hauv ib lub rooj tsavxwm.
Kev txiav txim siab tseem ceeb rau kev xaiv lossis tsim qauv PCB rau TFT LCD:
1. Interface sib xws:Xyuas kom cov PCB yuam kev TFT LCD lub interface hom (piv txwv li, LVDs, RGB, Mipi DSI).
2. Kev daws teeb meem thiab Refresh tus nqi:Tus PCB yuav tsum tau pab txhawb LCD kev daws teeb meem thiab tus nqi hloov kho kom ntseeg tau tias kev ua yeeb yam zoo.
3. Fais fab yuav tsum:Kuaj xyuas tias PCB muab qhov tseeb ntawm cov hluav taws xob thiab cov dej khov rau ob qho tib si TFT LCD thiab nws Backlight.
4. Connector thiab txheej:Xyuas kom meej tias cov txuas thiab pcb pcbout sib phim lub cev thiab hluav taws xob cov cai ntawm traft LCD.
5. Thermal tswj:Xav txog cov thermal yuav tsum muaj ntawm traft lcd thiab xyuas kom tus qauv PCB suav nrog kev ua cua sov txaus.
Piv txwv li kev siv:
Yog tias koj ua haujlwm TFT rau hauv qhov project kev cai, koj yuav pib nrog lub hom phiaj tswj hwm LCD uas txhawb nqa koj cov zaub daws teeb meem thiab kev sib cuam tshuam. Yog tias koj xav tau ntau yam kev ua haujlwm tshwj xeeb lossis tsim cov qauv kev cai, cov khoom siv tsav tsheb tsim nyog, thiab cov txuas txuas rau koj tus TFT txoj cai.
Los ntawm kev nkag siab no sib txawv ntawm cov pcb cov laug cam sib txawv thiab lawv cov kev ua haujlwm, koj tuaj yeem xaiv qhov tsim nyog rau koj tus lej TFT rau koj cov kev ua tau zoo thiab kev ua yeeb yam zoo hauv koj daim ntawv thov.
