Ho khetha se nepahetsengPCB (Boto e hatisitsoeng ea potoloho)ho bapisa leLCD (Pontšo ea Crystal ea Mokelikeli)e kenyelletsa lintlha tse 'maloa tsa bohlokoa ho netefatsa tšebelisano le ts'ebetso e nepahetseng. Mona ke tataiso ea mohato ka mohato ho u thusa ho etsa ts'ebetso ena:
1. Utloisisa Litlhaloso tsa LCD ea Hau
• Mofuta oa Sehokahanyi: Etsa qeto ea mofuta oa interface eo LCD ea hao e e sebelisang, joalo ka LVDS (Low-Voltage Differential Signaling), RGB (Red, Green, Blue), HDMI, kapa tse ling. Netefatsa hore PCB e ka tšehetsa sebopeho sena.
• Qeto le Boholo: Lekola qeto (mohlala, 1920x1080) le boholo ba 'mele ba LCD. PCB e lokela ho etsoa ho sebetsana le qeto e itseng le tlhophiso ea pixel.
• Litlhoko tsa Motlakase le Matla: Netefatsa litlhoko tsa motlakase le matla bakeng saPhanele ea LCDle backlight. PCB e lokela ho ba le lipotoloho tse nepahetseng tsa phepelo ea motlakase ho tsamaisana le litlhoko tsena.
2. Kgetha IC Controller
• Tšebelisano: Netefatsa hore PCB e kenyelletsa IC controller e tsamaellanang le lintlha tsa LCD tsa hau. Molaoli oa IC o tlameha ho khona ho laola qeto ea LCD, sekhahla sa ho nchafatsa, le sebopeho.
• Likarolo: Nahana ka likarolo tse ling tseo u ka li hlokang, joalo ka sekala se hahelletsoeng ka hare, tšebetso e hlahang skrineng (OSD), kapa likarolo tse itseng tsa taolo ea mebala.
3. Sheba Sebopeho sa PCB
• Tšebelisano ea Sehokelo: Netefatsa hore PCB e na le likhokahanyo tse nepahetseng bakeng sa phanele ea LCD. Netefatsa hore mefuta ea pinout le sehokelo e lumellana le sebopeho sa LCD.
• Tsamaiso ya Matshwao: Netefatsa hore sebopeho sa PCB se tshehetsa ho tsamaisa matshwao ka nepo bakeng sa data le mela ya taolo ya LCD. Sena se kenyelletsa ho lekola bophara ba trace wide le litsela ho thibela mathata a mats'oao.
4.Hlahloba Tsamaiso ea Matla
• Moralo oa Phepelo ea Motlakase: Etsa bonnete ba hore PCB e kenyelletsa lipotoloho tse loketseng tsa taolo ea matla ho fana ka li-voltages tse hlokahalang ho bobeliLCDle backlight ea eona.
• Backlight Control: Haeba LCD e sebelisa lebone la morao-rao, hlahloba hore na PCB e na le li-circuits tse loketseng ho laola khanya le matla a backlight.
5.Nahana ka Lintlha tsa Tikoloho
• Temperature Range: Netefatsa hore PCB e ka sebetsa ka har'a mocheso o fapaneng o hlokahalang bakeng sa kopo ea hau, haholo-holo haeba e tla sebelisoa libakeng tse thata.
• Ho tšoarella nako e telele: Haeba LCD e tla sebelisoa maemong a matsutla-tsutla, etsa bonnete ba hore PCB e etselitsoe ho mamella khatello ea maikutlo, ho sisinyeha, le ho pepesehela lintho tse ka bang teng.
6.Hlahloba Litokomane le Tšehetso
• Datasheets le Manuals: Hlahloba li-database le libuka tsa LCD le PCB ka bobeli. Etsa bonnete ba hore ba fana ka tlhahisoleseding e hlokahalang bakeng sa ho kopanya le ho rarolla mathata.
• Tšehetso ea Theknoloji: Nahana ka boteng ba tšehetso ea tekheniki ho tsoa ho moetsi oa PCB kapa mofani oa thepa haeba u ka kopana le mathata nakong ea kopanyo.
7.Prototype le Test
• Theha Sets'oants'o: Pele u itlama ho moralo oa ho qetela, etsa mohlala ho leka ho kopanya LCD le PCB. Sena se thusa ho tseba le ho rarolla mathata a ka bang teng.
• Hlahloba ka ho Fetisisa: Sheba lintlha tse kangpontsholintho tsa khale, ho nepahala ha mebala, le ts'ebetso ka kakaretso. Netefatsa hore PCB le LCD li sebetsa 'moho ntle ho nako.
Mokhoa oa ho etsa mohlala:
1. Etsa qeto ea LCD's Interface: Ha re re LCD ea hau e sebelisa sebopeho sa LVDS se nang le qeto ea 1920x1080.
2.Khetha Boto ea Taolo e Tšoanang: Khetha aPCBe nang le IC controller ea LVDS e tšehetsang qeto ea 1920x1080 mme e kenyelletsa likhokahano tse nepahetseng.
3. Netefatsa Litlhoko tsa Motlakase: Sheba li-circuits tsa motlakase tsa PCB ho netefatsa hore li lumellana le matla a LCD le litlhoko tsa hona joale.
4.Build and Test: Bokella likarolo, kopanya LCD ho PCB, 'me u leke bakeng sa ts'ebetso e nepahetseng ea pontšo le tshebetso.
Ka ho hlahloba ka hloko lintlha tsena, u ka khetha aPCBe tsamaellanang le litlhoko tsa LCD ea hau mme e netefatsa ts'ebetso e tšepahalang le ea boleng bo holimo.
DISEN Electronics Co., Ltd.e thehiloe ka 2020, ke setsebi sa LCD se bonts'ang, Touch panel le Display touch integrate solutions manufacturer ea sebetsanang ka ho khetheha le R&D, tlhahiso le maemo a ho bapatsa le LCD e ikhethileng le lihlahisoa tsa touch. Lihlahisoa tsa rona li kenyeletsa TFT LCD panel, TFT LCD module with capacitive and resistive touchscreen (support optical bonding le air bonding), le boto ea taolo ea LCD le boto ea taolo ea ho ama, pontšo ea indasteri, tharollo ea pontšo ea bongaka, tharollo ea PC ea indasteri, tharollo ea tloaelo ea pontšo,Boto ea PCBleboto ea molaolitharollo.
