PCB mabhodhi eTft LcDs ane nyanzvi yakadhindwa wedunhu matunhu akagadzirirwa kuti inyore uye kutongaTft (yakatetepa-firimu transistist) LCD inoratidza. Aya mabhodhi anowanzo batanidza akasiyana masangano ekutarisira kushanda kwekuratidzira uye nechokwadi chekutaurirana kwakakodzera pakati peLCD uye zvimwe zvehurongwa. Heano kuongorora kwemhando dzePCB mabhodhi anowanzo shandiswa neTft LCDs:
1. LCD Controller Mabhodhi
•Chinangwa:Aya mabhodhi anotarisira iyo interface pakati peTft LCD uye iyo huru yekugadzirisa chikamu chechishandiso. Ivo vanobata kushandurwa chiratidzo, kudzora nguva, uye maneja masimba.
•Zvimiro:
•Controller Mics:Yakabatanidzwa matunhu anogadzirisa masaini evhidhiyo uye kudzora kuratidzwa.
•Vanobatanidza:Zvitoro zvekubatanidza kune iyo LCD Panel (semuenzaniso, LVDS, RGB) uye iyo huru mudziyo (semuenzaniso, HDM, VGA).
•Simba Matunhu:Ipa simba rinodiwa kune ese aratidziro uye ayo kumashure.
2. Mabhodhi vatyairi
• Chinangwa:Mabhodhi emutyairi anodzora kushanda kweiyo tft LCD pane imwe nhanho yekudonha, kutarisa nezvekutyaira pixels imwe neimwe uye kugadzirisa maitiro ekuratidzira.
•Zvimiro:
• Driver Driver:Nyanzvi dzakakosha dzinofambisa mapikisheni eiyo tft kuratidza uye kugadzirisa rizororo rizero.
•Interface kuwirirana:Mabhodhi akagadzirirwa kushanda neye chaiyo tft LCD mapaneru uye yavo yakasarudzika chiratidzo zvinodiwa.
3. Mabhodhi emukati
• Chinangwa:Aya mabhebhi anofambisa kubatana pakati peTft LCD uye zvimwe zvikamu zvehurongwa, zvichishandura uye kuendesa masaini pakati pemasangano akasiyana.
•Zvimiro:
•Signal Shanduko:Inoshandura masaini pakati pezvikamu zvakasiyana (semuenzaniso, lvds to rgb).
•Connector mhando:Inosanganisira dzakasiyana siyana dzinobatanidza kuti dzifanane neiyo tft LCD uye iyo system yeSystem inobuda.
4. Backlight vatyairi mabhodhi
•Chinangwa:Kuzvitsaurira kusimba uye kudzora iyo backlight yeTft LCD, iyo yakakosha kuratidza kuoneka.
•Zvimiro:
•Backlight Kudzora Tics:Bata kupenya uye simba rekusvika kumashure.
•Magetsi Suppty Dunhu:Ipa iyo inodiwa voltage uye ikozvino kune iyo yekumberi.
5. Tsika pcbs
•Chinangwa:Tsika-Yakagadzirirwa PCBS yakagadziriswa kune chaiyo tft lcd application, kazhinji inodiwa kuti azivikanwe kana akasarudzika ekuratidzira.
•Zvimiro:
•Dhizaini yakagadziridzwa:Tsika layyuts uye kutenderera kuti usangane chaizvo zvinodiwa zveTft LCD uye application yayo.
•Kubatanidzwa:Inogona kusanganisa controller, mutyairi, uye masimba mashandiro emasimba emabasa mune imwe bhodhi.
Kufunga Key kwekusarudza kana kugadzira PCB yeTft LCD:
1. Enterface kuwirirana:Ita shuwa PCB inoenderana neTft LCD's InterFAce mhando (semuenzaniso, LVD, RGB, Mipi DSI).
2. Resolution uye zororo rezororo:Iyo PCB inofanirwa kutsigira iyo LCD's resolution uye zororo rekuzorodza kuti uve nechokwadi chekuratidzira kwekuratidzira.
3. Zvinodiwa nePower:Tarisa kuti PCB inopa voltage chaiyo uye mafungu eiyo tft lcd uye kwayo kumashure.
4. Kubatanidza uye chimiro:Ita shuwa kuti kubatana uye PCB chimiro chinoenderana nezvinodiwa zvemuviri uye zvemagetsi zveTft LCD.
5. Inodzidzisa manejimendi:Funga nezve izvo zvinowanzoitika zvinodiwa neTft LCD uye ona kuti PCB Dhizaini inosanganisira yakakwana kupisa kupisa kwekupisa.
Muenzaniso weShizha:
Kana iwe uri kuunganidza tft lcd mune chirongwa chetsika, unogona kutanga uine general-chinangwa LCD Controller Board iyo inotsigira yako yekugadzirisa resolution uye interface. Kana iwe uchida mamwe maitiro ezvekuita kana tsika
Nekunzwisisa aya marudzi akasiyana ePCB mabhodhi uye mashandiro avo, iwe unogona kusarudza zviri nani kana kugadzira iyo PCB yeTft yako yeTft kuratidza, ichisanganisira kuwirirana uye kuita chiitiko chakakwana mukushandisa kwako.
