Amabhodi we-PCB we-TFT LCD angama-pried ephrintiwe ephrintiwe eklanyelwe ukuxhumeka nokulawulaI-TFT (Thin-Film-Film Transistor) Ekhombisa LCD. Lawa mabhodi ajwayele ukuhlanganisa ukusebenza okuhlukahlukene ukuphatha ukusebenza kokubonisa futhi aqinisekise ukuxhumana okufanele phakathi kwe-LCD kanye nohlelo lonke. Nakhu ukubuka konke kwezinhlobo zamabhodi we-PCB asetshenziswa kakhulu nge-TFT LCDS:
1. Amabhodi e-LCD alawulayo
•INJONGO:Lawa mabhodi aphatha isikhombimsebenzisi phakathi kwe-TFT LCD kanye neyunithi eliphambili ledivayisi. Baphatha ukuguqulwa kwesiginali, ukulawulwa kwesikhathi, kanye nokuphathwa kwamandla.
•Izici:
•I-Controller ICS:Imibuthano ehlanganisiwe ecubungula amasiginali wevidiyo futhi ilawula isibonisi.
•Izixhumi:Amachweba okuxhuma kwiphaneli ye-LCD (isib. Ama-LVD, RGB) kanye nedivayisi eyinhloko (isib. HDMI, VGA).
•Imibuthano yamandla:Nikeza amandla adingekayo womabili okuboniswa kanye nokukhanya kwawo.
2. Amabhodi Okushayela
Inhloso:Amabhodi okushayela alawule ukusebenza kwe-TFT LCD ezingeni eliphakeme kakhulu, egxile ekushayeleni amaphikiseli athile nokuphatha ukusebenza kwe-Display.
•Izici:
• I-Driver ICS:Ama-chips akhethekile ashayela amaphikseli okuboniswa kwe-TFT futhi aphathe amanani okuvuselela.
•Ukuvumelana okubonakalayo:Amabhodi aklanyelwe ukusebenza ngamaphaneli athile we-TFT LCD nezidingo zazo ezihlukile zesiginali.
3. Amabhodi ezibonakalayo
Inhloso:Lawa mabhodi enza lula ukuxhumana phakathi kwe-TFT LCD kanye nezinye izinto zohlelo, ukuguqula kanye nezimpawu zomzila phakathi kwezindawo ezahlukahlukene.
•Izici:
•Ukuguqulwa kwesiginali:Iguqula amasiginali aphakathi kwamazinga ahlukene (isib. Ama-LVD kuya ku-RGB).
•Izinhlobo zesixhumi:Kubandakanya izixhumi ezahlukahlukene ukufanisa zombili i-TFT LCD kanye nezindawo zokuphuma zohlelo.
4. Amabhodi Wokushayela Emuva
•INJONGO:Kunikezelwe amandla futhi kulawulwa ukukhanya kwe-TFT LCD, okubalulekile ukuze kuboniswe ukubonakala.
•Izici:
•Ukulawulwa kwe-Backlight ICS:Phatha ukugqama namandla e-backlight.
•Imibuthano Yokunikeza Amandla:Nikeza nge-voltage edingekayo futhi yamanje kuya emuva.
5. Ama-PCB
•INJONGO:Ama-PCB aklanywe ngokwezifiso ahlelwe kwizicelo ezithile ze-TFT LCD, evame ukudingeka ukuboniswa okuhlukile noma okukhethekile.
•Izici:
•Idizayini eyenziwe nge-coentical:Ukuhlelwa ngokwezifiso kanye nokujikeleza ukuze kuhlangatshezwane nezidingo ezithile ze-TFT LCD kanye nesicelo sayo.
•Ukuhlanganiswa:Ungahlanganisa isilawuli, umshayeli, kanye nemisebenzi yokuphatha amandla ebhodini elilodwa.
Ukucatshangelwa okusemqoka kokukhetha noma ukuklama i-PCB ye-TFT LCD:
1. Ukuvumelana okubonakalayo:Qinisekisa ukuthi i-PCB ifana nohlobo lwe-TFT LCD (isib., LVD, RGB, Mipi DSI).
2. Ukulungiswa kanye nokuqabula isilinganiso:I-PCB kumele isekele ukulungiswa kwe-LCD kanye nokuvuselela isilinganiso ukuze kuqinisekiswe ukusebenza kahle kokubonisa.
3. Izidingo zamandla:Bheka ukuthi i-PCB ihlinzeka ngama-voltages afanele kanye nemisinga ye-TFT LCD kanye nokukhanya kwayo.
4. Isixhumi nesakhiwo:Qinisekisa ukuthi izixhumi kanye nesakhiwo se-PCB zifana nezidingo zomzimba nezikagesi ze-TFT LCD.
5. Ukuphathwa kwe-Thermal:Cabanga ngezidingo ezishisayo ze-TFT LCD futhi uqinisekise ukuthi i-PCB Design ifaka ukushiyeka okuvuthayo okwanele.
Isibonelo sokusetshenziswa:
Uma uhlanganisa i-TFT LCD kwiphrojekthi yangokwezifiso, ungaqala ngebhodi elijwayelekile le-LCD alawulwa yi-LCD elisekela ukulungiswa kwesibonisi sakho kanye nesibonisi. Uma udinga ukusebenza okuthile okuqondene noma izici zangokwezifiso, ungahle ukhethe noma uhlele noma uhlele i-PCB yangokwezifiso efaka isilawuli esidingekayo i-ICS, iziqebele zemishayeli, nezixhumi ezihambelana nezidingo zakho ze-TFT LCD.
Ngokuqonda lezi zinhlobo ezahlukahlukene zamabhodi e-PCB kanye nokusebenza kwazo, ungakhetha kangcono noma udwebe i-PCB efanelekile yokubonisa kwakho kwe-TFT LCD, ukuqinisekisa ukuhambisana nokusebenza okuhle kuhlelo lwakho lokusebenza.
