Hordhaca interface LVDS ee shaashadda TFT-LCD ee LCD

Qeexida Interface-ka LVDS

Qeexida Interface-ka LVDS waxa ay tilmaamaysaa shaqada LVDS-ga xidhidhiyaha dhamaadka-interface-ka ee dhinaca dhinaca LCD-ga, kaas oo guud ahaan lagu baran karo la talinta xogta warshada asalka ah ee shaashadda LCD (badanaa loo yaqaan buugga sifaynta shaashadda). In kasta oo heerarka kala duwan ee Ingiriisiga ee shaqada interface screen LCD ay kala duwan yihiin, laakiin ma adka in la arko taas, iyadoo la eegayo nidaamka xarfaha iyo lambarada muhiimka ah, Tusaale ahaan, shaashad LCD ah oo CLAA170EA02 gaar ah, Fiiri shaxda qeexitaanka interface ee ay bixiso soo saaraha, Sida laga arki karo tiir gaaban oo Ingiriis ah, RXO iyo RXE, Kanaal kastaa wuxuu leeyahay lambarka "0″ ~ "3″ xogta kooxda, wuxuuna leeyahay 1 set oo ah calaamadaha saacadaha (RXOC ama RXEC), Tani waxay muujinaysaa in shaashadda LCD ay tahay 30-pin, dual, 8-bit screen, Sidoo kale ma adka in la arko shaqadiisa pin, Taas oo ah, "RXO0-" waxay u taagan tahay xogta ugu horreysa 1- , "RXO0 +" macnaheedu waa xogta ugu horreysa: 1 +; "RXE0-" waxay tilmaamaysaa xogta labaad ee 1-, "RXE0 +" waxay muujinaysaa xogta labaad ee 1 +, Inta kale, iyo wixii la mid ah. Interface-ka LVDS waxa uu leeyahay LVDS waa Ingiriis gaaban oo gaaban “Sonaamijka Kaladuwanaanta Korantada Hoose” oo macnaheedu yahay calaamada kala duwanaanta cadaadiska hoose. LVDS waxay ka gudubtaa faa'iido darrada gudbinta isticmaalka awoodda sare ee broadband iyo EMI faragelinta korantada ee qaabka heerka TTL, waana habka gudbinta calaamadaha fiidiyoowga dhijitaalka ah. Isku-xidhka wax-soo-saarka LVDS wuxuu isticmaalaa lulid koronto oo aad u hooseeya (qiyaastii 350mV) si uu xogta ugu gudbiyo farqi u dhexeeya laba fiilood oo PCB ah ama laba xargo oo dheelitiran. Interface-ka LVDS waxa uu ku gudbiyaa calaamada PCB-ga kala duwan ama fiilada dheelitirka oo ah qiyaas boqollaal megbits ilbiriqsikii. Sababo la xiriira koronta yar iyo habka wadista hadda hooseeya, waxay leedahay faa'iidooyinka qaylada hoose iyo isticmaalka tamarta yar. TV-ga midabka LCD, laynka LVDS waxa uu isticmaalaa fiilo dheeli tiran inta badan, dhab ahaantii waa xariiq lammaane qalloocan. Qaybta wareegga wareegga LVDS ee TV-ga midabka LCD ama muujinta midabka marka ugu horreysa ee dejinta calaamadaha soo-gelinta (sida TV, AV, iwm.), si loo helo calaamadda RGB, nidaamkeedu asal ahaan wuxuu la mid yahay TV-ga midabka caadiga ah, iyo ka dib iyada oo loo marayo beddelka RGB-LVDS, soo saarista calaamadda LVDS, oo loo diro shaashadda LCD. Mar haddii TFT-ga ku jira shaashadda LCD uu aqoonsanayo calaamadda TTL (RGB), LVDS ee loo soo diro shaashadda LCD waxay u baahan tahay inay dejiso calaamadda TTL. Waxaa la arki karaa in wareegga LVDS interface ay ku jiraan laba qaybood: wareegga wax soo saarka LVDS ee dhinaca Motherboard-ka (LVDS transmitter), iyo LVDS input interface circuit (LVDS receiver) ee dhinaca LCD-ga. Terminalka gudbinta LVDS wuxuu u beddelaa calaamadda TTL ee calaamadda LVDS, ka dibna u gudbiya calaamadda LVDS-ka-dejinta IC ee dhinaca guddida LCD iyada oo loo marayo fiilada safka ah ama fiilada dabacsan ee u dhexeeya guddiga wadista iyo guddiga LCD), u beddela signalka taxanaha ah calaamad is barbar ah oo ah heerka TTL, ka dibna u diraya kontoroolka wakhtiga LCD iyo darajooyinka wareegga wadista.
