•Iimbonakalo:
•Umlawuli ICs:Iisekethe ezidityanisiweyo ezenza imiqondiso yevidiyo kwaye zilawule isiboniso.
•Iziqhagamshelo:Iizibuko zokuqhagamshela kwipaneli ye-LCD (umzekelo, i-LVDS, i-RGB) kunye nesixhobo esingundoqo (umzekelo, i-HDMI, i-VGA).
•IiSekethi zaMandla:Nika amandla afunekayo kuzo zombini isiboniso kunye nesibane saso sangasemva.
2. Iibhodi zabaqhubi
• Injongo:Iibhodi zomqhubi zilawula ukusebenza kwe-TFT LCD kwinqanaba legranular ngakumbi, ligxile ekuqhubeni ipixels nganye kunye nokulawula ukusebenza komboniso.
•Iimbonakalo:
• Ii-ICs zomqhubi:Iichips ezikhethekileyo eziqhuba iipixels zomboniso weTFT kwaye zilawule amazinga okuhlaziya.
•Ukuhambelana kojongano:Iibhodi ezilungiselelwe ukusebenza kunye neepaneli ze-LCD ze-TFT kunye neemfuno zabo zomqondiso ezizodwa.
3. Iibhodi zonxibelelwano
• Injongo:Ezi bhodi ziququzelela uxhulumaniso phakathi kwe-TFT LCD kunye namanye amacandelo enkqubo, ukuguqula kunye nemiqondiso yomzila phakathi kojongano oluhlukeneyo.
•Iimbonakalo:
•Uguqulo loMqondiso:Iguqula imiqondiso phakathi kwemigangatho eyahlukeneyo (umzekelo, i-LVDS ukuya kwi-RGB).
•Iintlobo zesiqhagamshelo:Ibandakanya izihlanganisi ezahlukeneyo ukuze zitshatise zombini i-TFT LCD kunye nojongano lwemveliso yenkqubo.
4. Iibhodi zomqhubi we-Backlight
•Injongo:Ukunikezelwa kwamandla kunye nokulawula ukukhanya kwe-backlight ye-TFT LCD, ebalulekileyo ekuboniseni ukubonakala.
•Iimbonakalo:
•Ulawulo lwesibane sangasemva ICs:Lawula ukuqaqamba kunye namandla isibane esingasemva.
•IiSekethe zoBonelelo lwaMandla:Nika i-voltage efunekayo kunye nekhoyo kwi-backlight.
5. PCBs Custom
•Injongo:IiPCB eziyilwe ngokwesiqhelo ezenzelwe usetyenziso oluthile lwe-TFT LCD, esoloko ifuneka kwimiboniso eyodwa okanye ekhethekileyo.
•Iimbonakalo:
•Uyilo olulungiselelweyo:Uyilo olulungiselelweyo kunye neesekethe ukuhlangabezana neemfuno ezithile ze-TFT LCD kunye nokusetyenziswa kwayo.
•Udibaniso:Inokudibanisa umlawuli, umqhubi, kunye nemisebenzi yokulawula amandla kwibhodi enye.
Iingqwalasela eziphambili zokuKhetha okanye ukuYila iPCB ye-TFT LCD:
1. Ukuhambelana koMsebenzi:Qinisekisa ukuba iPCB ihambelana nohlobo lojongano lwe-TFT LCD (umz., LVDS, RGB, MIPI DSI).
2. Isisombululo kunye nenqanaba lokuhlaziya:I-PCB kufuneka ixhase ukusonjululwa kwe-LCD kunye nezinga lohlaziyo ukuze kuqinisekiswe umboniso wokusebenza okugqwesileyo.
3. IiMfuno zaMandla:Khangela ukuba iPCB ibonelela ngeevoltheji ezichanekileyo kunye nemisinga yazo zombini i-TFT LCD kunye nesibane sayo sangasemva.
4. Isiqhagamshelo kunye noYilo:Qinisekisa ukuba iziqhagamshelo kunye noyilo lwePCB luhambelana neemfuno zomzimba nezombane ze-TFT LCD.
5. Ulawulo lweThermal:Qwalasela iimfuno ezishushu ze-TFT LCD kwaye uqinisekise ukuba uyilo lwePCB lubandakanya ukuchithwa kobushushu okwaneleyo.
Umzekelo wokusetyenziswa:
Ukuba udibanisa i-TFT LCD kwiprojekthi yesiko, unokuqala ngebhodi yesilawuli ye-LCD yenjongo jikelele exhasa isisombululo somboniso wakho kunye nojongano. Ukuba ufuna ukusebenza okuthe ngqo okanye iimpawu zesiko, ungakhetha okanye uyile iPCB yesiko edibanisa isilawuli esiyimfuneko ii-ICs, iisekethe zomqhubi, kunye nezihlanganisi ezilungiselelwe iimfuno ze-TFT LCD yakho.
Ngokuqonda ezi ntlobo zahlukeneyo zeebhodi zePCB kunye nokusebenza kwazo, unokukhetha ngcono okanye uyile iPCB efanelekileyo kumboniso wakho we-TFT LCD, uqinisekise ukuhambelana nokusebenza okugqwesileyo kwisicelo sakho.
