Looxyada PCB ee TFT LCDs waa loox wareegyo daabacan oo khaas ah oo loogu talagalay in lagu xakameeyoTFT (Thin-Filim Transistor) LCD bandhigyo. Looxyadani waxay caadi ahaan isku daraan hawlo kala duwan si loo maareeyo hawlgalka bandhiga oo loo hubiyo xidhiidhka saxda ah ee u dhexeeya LCD iyo nidaamka intiisa kale. Waa kuwan dulmar ku saabsan noocyada looxyada PCB ee sida caadiga ah loo isticmaalo TFT LCDs:
1. Guddiyada Xakamaynta LCD
•Ujeedada:Looxyadani waxay maamulaan is-dhexgalka u dhexeeya TFT LCD iyo unugga farsamaynta ee aaladda. Waxay qabtaan beddelka calaamadaha, xakamaynta wakhtiga, iyo maamulka awoodda.
•Astaamaha:
•Xakamaynta ICs:Wareegyo isku dhafan oo ka shaqeeya calaamadaha muuqaalka oo xakameeya bandhigga.
•Xidhiidhiyayaasha:Dekadaha loogu xidho guddida LCD (tusaale, LVDS, RGB) iyo aaladda ugu muhiimsan (tusaale, HDMI, VGA).
•Wareegyada Korontada:Sii awoodda lagama maarmaanka u ah labadaba bandhigga iyo iftiinka dambe.
2. Guddiyada Darawalka
Ujeedo:Looxyada darawaladu waxay maamulaan shaqada TFT LCD si heer sare ah, iyagoo diiradda saaraya wadista pixels-ka gaarka ah iyo maaraynta waxqabadka bandhigga.
•Astaamaha:
• Darawalka ICs:Chips gaar ah oo kaxeeya pixels ee bandhigga TFT oo maamula heerarka soo kicinta.
•Waafaqsanaanta Interface:Looxyada loogu talagalay inay la shaqeeyaan muraayadaha TFT LCD gaar ah iyo shuruudaha calaamadaha gaarka ah.
3. Looxyada Interface
Ujeedo:Looxyadani waxay fududeeyaan xidhiidhka ka dhexeeya TFT LCD iyo qaybaha kale ee nidaamka, beddelidda iyo marinka calaamadaha u dhexeeya is-dhexgalka kala duwan.
•Astaamaha:
•Beddelka ishaarka:U beddelaa calaamadaha u dhexeeya heerar kala duwan (tusaale, LVDS ilaa RGB).
•Noocyada Xiriiriyaha:Waxa ku jira xidhiidhiyayaal kala duwan oo ku habboon labada TFT LCD iyo nidaamka wax-soo-saarka interfaces.
4. Looxyada Darawalka iftiinka dambe
•Ujeedada:U heellan in lagu koro oo xakameeyo nalka dambe ee TFT LCD, kaas oo lagama maarmaan u ah muuqaalka muuqaalka.
•Astaamaha:
•Xakamaynta iftiinka dambe ee ICs:Maamul dhalaalka iyo xoogga iftiinka dambe
•Wareegyada Bixinta Korontada:Bixi tamarta loo baahan yahay iyo hadda iftiinka dambe.
5. PCB-yada gaarka ah
•Ujeedada:PCB-yada gaarka ah ee loo qaabeeyey ee ku habboon codsiyada gaarka ah ee TFT LCD, oo inta badan looga baahan yahay bandhigyo gaar ah ama khaas ah.
•Astaamaha:
•Naqshad La Haboon:Qaababka gaarka ah iyo wareegyada si loo buuxiyo shuruudaha gaarka ah ee TFT LCD iyo codsigeeda.
•Is dhexgalka:Waxay isku dari kartaa kontaroolaha, darawalka, iyo hawlaha maaraynta awooda hal guddi
Tixgelinta Muhiimka ah ee Doorashada ama Naqshadaynta PCB ee TFT LCD:
1. Waafaqsanaanta Interface:Hubi in PCB-gu uu la mid yahay TFT LCD-ga is-dhexgalka (tusaale, LVDS, RGB, MIPI DSI).
2. Xallinta iyo Heerka Cusbooneysiinta:PCB-gu waa in uu taageeraa xallinta LCD-ga iyo heerka dib-u-cusboonaysiinta si loo hubiyo waxqabadka bandhigga ugu fiican.
3. Shuruudaha Korontada:Hubi in PCB-gu bixiyo tamarta saxda ah iyo qulqulka labada TFT LCD iyo iftiinkeeda dambe.
4. Xidhiidhiyaha iyo Qaabaynta:Hubi in isku xidhayaasha iyo qaabaynta PCB ay ku habboon yihiin shuruudaha jidheed iyo korantada ee TFT LCD.
5. Maamulka kulaylka:Tixgeli shuruudaha kulaylka ee TFT LCD oo hubi in naqshadaynta PCB ay ku jirto daadinta kulayl ku filan.
Tusaalaha Isticmaalka:
Haddii aad ku dhex darayso TFT LCD mashruuc caado ah, waxa laga yaabaa in aad ku bilowdo guddi kontorool LCD ujeedo-guud ah kaas oo taageeraya xallinta bandhiggaaga iyo is-dhexgalkaaga. Haddii aad u baahan tahay hawlo gaar ah oo gaar ah ama astaamo gaar ah, waxaad dooran kartaa ama aad qaabayn kartaa PCB caado ah oo ka kooban kontaroolaha lagama maarmaanka ah ICs, wareegyada darawalka, iyo xirayaasha ku habboon shuruudaha TFT LCD.
Markaad fahamto noocyadan kala duwan ee looxyada PCB-ga iyo hawlahooda, waxaad si fiican u dooran kartaa ama u qaabayn kartaa PCB-ga ku habboon bandhigaaga TFT LCD, adiga oo hubinaya in ku habboonaanta iyo waxqabadka ugu wanaagsan ee codsigaaga.
