Likheo tsa PCB bakeng sa li-LFD tse hatisitsoeng li ngotsoe hantle ka bongata ba potoloho tse hatisitsoeng tse etselitsoeng ho fetoloa le ho laolaTRS (transtistor ea lifilimi e tšesaane) lcd. Litoropo tsena li hokahanya likarolo tse fapaneng ho sebetsana le ts'ebetso ea pontšo le ho netefatsa puisano e nepahetseng pakeng tsa LCD le sistimi e setseng. Kakaretso ea mefuta ea mefuta ea mekhahlelo ea PCB e sebelisoa ka tatellano ea li-LFD:
1. Li-controller Boards
•Morero:Mabatomo ana a sebetsana le sebopeho pakeng tsa TFD LCD le karolo e kholo ea sesebelisoa. Ba sebetsana le phetoho ea lipontšo, taolo ea nako le taolo ea matla.
•Likaroloana:
•Likarolo tsa tsamaiso:Liporete tse kopaneng tse sebelisang lipontšo tsa video le ho laola pontšo.
•Lihokela:Likomo tsa ho hokahana le phanele ea LCD (mohlala, LVD, RGB) le sesebelisoa sa mantlha (mohlala, HDMI, vGA).
•Lipotolooa tsa Matla:Fana ka matla a hlokahalang bakeng sa lipontšo le ho mokokotlo oa ona.
2. Likopano tsa mokhanni
• Morero:Maboto a khanno a laola ts'ebetso ea TFT LCD Boemong ba granular, e shebisisa ho khanna lipeiseng ka bomong le ho tsamaisa tšebetso ea poxels.
•Likaroloana:
• Litšoantšo tsa mokhanni:Li-Chips tse khethehileng tse tsamaisang li-pixels tsa lipontšo tsa TFT.
•Setsi sa Intermaciated:Litoropo li etselitsoe ho sebetsa le li-panels tse khethehileng tsa maqhubu a monate le litlhoko tsa bona tse ikhethang tsa matšoao.
3. Metato ea linomoro
• Morero:Likhetla tsena li tsamaisa kamano lipakeng tsa li-LFD LCD le likarolo tse ling tsa sistimi, ho fetolela matšoao a tsamaeang pakeng tsa mefuta e fapaneng.
•Likaroloana:
•Signal Phetoho:E fetola lipontšo lipakeng tsa litekanyetso tse fapaneng (mohlala, LVDs ho RGB).
•Mefuta ea Khokahano:Ho kenyelletsa lichintoctory tse fapaneng ho tsamaisana le li-icd tse boletsoeng ka holimo le mefuta ea tsamaiso ea tsamaiso.
4. Mekotla ea mokhanni oa mokokotlo
•Morero:Inehetse ho matla le ho laola khanya ea morao-rao ea TFD LCD, e leng ea bohlokoa bakeng sa ho bonts'a ponahalo.
•Likaroloana:
•Setsi sa Taolo ea Backlight Is:Laola khanya le matla a mokokotlo.
•Litefiso tsa Phepelo:Fana ka Voltage e hlokahalang le ea hajoale ho ea morao.
5. Li-PCB tsa moetlo
•Morero:Li-PCbs tse entsoeng ka tloaelo li tsamaisa likopo tse ikhethang tsa TFD, hangata li hlokahala bakeng sa lipontšo tse ikhethang kapa tse ikhethang.
•Likaroloana:
•Moralo oa Taishene:Meelelo ea moetlo le potoloho ea ho etsa litlhoko tse ikhethileng tsa LFT LFD le ts'ebeliso ea eona.
•Khokahano:E ka kopanya molaoli oa molaoli, mokhanni, mekhahlelo ea matla a matla a sebetsa boto e le 'ngoe.
Ke ile ka nahana ka ho khetha kapa ho rala pocb bakeng sa tcd:
1. TLHOKOMELISO E RATANG:Etsa bonnete ba hore pcb e tsamaisana le mofuta oa sehokelo sa TFD LCD (mohlala, Lvds, RGB, mipi dsi).
2. TLHOKOMELISO LE LEBAKA:PCB e tlameha ho tšehetsa tharollo ea LCD le theko ea ho phomola ho netefatsa ts'ebetso ea pontšo ea pontšo.
3. Litlhokahalo tsa matla:Lekola hore PCB e fana ka liforeithara tse nepahetseng le maqhubu a marang-rang bakeng sa bobeli le mokokotlo oa ona.
4. Khokahano le sebopeho:Etsa bonnete ba hore li-amctors le PCB li tsamaisana le litlhoko tsa 'mele le tsa motlakase tsa TFT LCD.
5. Tsamaiso ea Maqhubu:Nahana ka litlhokahalo tsa futhumatsang tsa tcd LCD le ho netefatsa moralo oa PCB ho kenyelletsa ho se tsebe letho.
Mohlala oa Phepelo:
Haeba u kopanya letheba la LCD LFD projeke ea tloaelo, u ka qala ka boto ea Molao-motheo e akaretsang e tšehetsang qeto ea hau ea pontšo ea pontšo ea hau. Haeba o hloka ts'ebetso e itseng e sebetsang kapa likarolo tsa moetlo, o kanna oa khetha pcb ea moetlo e kenyelletsang litlhokahalo tsa mokhanni.
Ka ho utloisisa mefuta ena e fapaneng ea liboto tsa PCB le lits'ebetso tsa bona, u ka khetha ponahalo e nepahetseng bakeng sa pontsho ea hau ea TFT LCD bakeng sa ts'ebeliso ea hau.
