Kusankha choyeneraPCB (Bungwe Losindikizidwa Lozungulira)kufananiza ndiLCD (Chiwonetsero cha Crystal chamadzimadzi)imaphatikizapo zinthu zingapo zofunika kuti zitsimikizire kuti zimagwirizana komanso kuchita bwino. Nawa kalozera watsatane-tsatane kuti akuthandizeni kuchita izi:
1. Mvetserani Zofunikira za LCD Yanu
• Mtundu wa Chiyankhulo: Dziwani mtundu wa mawonekedwe omwe LCD yanu imagwiritsira ntchito, monga LVDS (Low-Voltage Differential Signaling), RGB (Red, Green, Blue), HDMI, kapena ena. Onetsetsani kuti PCB ikhoza kuthandizira mawonekedwe awa.
• Kusamvana ndi Kukula kwake: Yang'anani kusamvana (monga 1920x1080) ndi kukula kwake kwa LCD. PCB iyenera kupangidwa kuti igwirizane ndi kusamvana ndi ma pixel.
• Zofunikira za Voltage ndi Mphamvu: Tsimikizirani voteji ndi zofunikira zamagetsi paLCD panelndi backlight. PCB iyenera kukhala ndi mabwalo oyenera operekera mphamvu kuti agwirizane ndi izi.
2. Sankhani Right Controller IC
• Kuyang'ana: Onetsetsani kuti PCB ili ndi chowongolera IC chomwe chikugwirizana ndi zomwe LCD yanu ikufuna. Woyang'anira IC ayenera kukhala wokhoza kuyang'anira kusamvana kwa LCD, kutsitsimula, ndi mawonekedwe.
• Zomwe Zilipo: Ganizirani zina zomwe mungafunikire, monga ma sikelo omangidwa mkati, mawonekedwe a on-screen display (OSD), kapena kasamalidwe ka mitundu.
3. Onani Mapangidwe a PCB
• Kugwirizana kwa Cholumikizira: Onetsetsani kuti PCB ili ndi zolumikizira zolondola pagawo la LCD. Onetsetsani kuti mitundu ya pinout ndi cholumikizira ikufanana ndi mawonekedwe a LCD.
• Mayendedwe a Signal: Tsimikizirani kuti masanjidwe a PCB amathandizira kuyatsa koyenera kwa ma data a LCD ndi mizere yowongolera. Izi zikuphatikizapo kuyang'ana m'lifupi mwake ndi njira kuti mupewe zovuta za kukhulupirika kwa chizindikiro.
4.Review Power Management
• Power Supply Design: Onetsetsani kuti PCB ikuphatikiza mabwalo oyenera owongolera mphamvu kuti apereke ma voltages ofunikira ku onse awiriLCDndi backlight yake.
• Kuwongolera Kuwala Kwam'mbuyo: Ngati LCD imagwiritsa ntchito nyali yakumbuyo, onetsetsani kuti PCB ili ndi mabwalo oyenerera kuti athe kuwongolera kuwala ndi mphamvu za backlight.
5.Ganizirani Zinthu Zachilengedwe
• Kutentha kosiyanasiyana: Onetsetsani kuti PCB ikhoza kugwira ntchito mkati mwa kutentha komwe kumafunikira pa ntchito yanu, makamaka ngati idzagwiritsidwa ntchito m'madera ovuta.
• Kukhalitsa: Ngati LCD idzagwiritsidwa ntchito m'malo ovuta, onetsetsani kuti PCB idapangidwa kuti izitha kupirira kupsinjika kwa thupi, kugwedezeka, komanso kukhudzana ndi zinthu.
6.Review Zolemba ndi Thandizo
• Ma Datasheets ndi Maupangiri: Unikaninso zinsinsi ndi zolemba za LCD ndi PCB. Onetsetsani kuti akupereka zidziwitso zofunikira pakuphatikiza ndi kuthetsa mavuto.
Thandizo Laukadaulo: Ganizirani za kupezeka kwa chithandizo chaukadaulo kuchokera kwa opanga PCB kapena ogulitsa ngati mukukumana ndi zovuta pakuphatikiza.
7.Prototype ndi Mayeso
• Pangani Prototype: Musanapange kupanga komaliza, pangani chithunzithunzi kuti muyese kuphatikiza kwa LCD ndi PCB. Izi zimathandiza kuzindikira ndi kuthetsa mavuto omwe angakhalepo.
• Yesani Bwinobwino: Yang'anani zinthu mongachiwonetserozojambulajambula, kulondola kwamitundu, komanso magwiridwe antchito onse. Onetsetsani kuti PCB ndi LCD zimagwira ntchito limodzi mosavutikira.
Ndondomeko Yachitsanzo:
1.Tsimikizirani mawonekedwe a LCD: Tiyerekeze kuti LCD yanu imagwiritsa ntchito mawonekedwe a LVDS ndi 1920x1080 resolution.
2.Sankhani Bungwe Lolamulira Logwirizana: Sankhani aPCByokhala ndi IVDS controller IC yomwe imathandizira 1920x1080 resolution ndipo imaphatikizapo zolumikizira zoyenera.
3.Verify Power Requirements: Yang'anani mabwalo amagetsi a PCB kuti muwonetsetse kuti akugwirizana ndi magetsi a LCD ndi zosowa zamakono.
4.Build and Test: Sonkhanitsani zigawozo, gwirizanitsani LCD ku PCB, ndikuyesani momwe mungagwiritsire ntchito bwino ndi ntchito.
Poganizira mozama zinthu izi, mutha kusankha aPCBzomwe zimagwirizana ndi zofunikira za LCD yanu ndikuwonetsetsa kuti chiwonetserochi chikuwoneka chodalirika komanso chapamwamba.
Malingaliro a kampani DISEN Electronics Co., Ltd.kukhazikitsidwa mu 2020, ndi katswiri wowonetsa LCD, Touch panel ndi Display touch integrate solutions opanga omwe amagwiritsa ntchito R&D, kupanga ndi kutsatsa mulingo ndi LCD makonda ndi zinthu zogwira. Zogulitsa zathu zikuphatikizapo gulu la TFT LCD, gawo la TFT LCD lokhala ndi capacitive ndi resistive touchscreen (thandizo lothandizira kuwala ndi mpweya wa mpweya), ndi bolodi loyang'anira LCD ndi bolodi loyang'anira kukhudza, chiwonetsero cha mafakitale, njira yowonetsera zamankhwala, njira ya PC ya mafakitale, njira yowonetsera mwambo,Chithunzi cha PCBndigulu lolamulirayankho.
