Te whakataki i te atanga LVDS o te mata LCD TFT-LCD

Te Whakamāramatanga o te Atanga LVDS

Ko te whakamāramatanga atanga LVDS e pā ana ki te mahi pine atanga pito whakauru LVDS i te taha o te papa LCD, e taea ana te ako mā te tirotiro i ngā raraunga wheketere taketake o te mata LCD (e kiia ana ko te pukapuka whakatakotoranga mata). Ahakoa he rerekē ngā paerewa Ingarihi o te mahi atanga mata LCD, ehara i te mea uaua ki te kite i tēnā, i runga i te raupapa o ōna reta me ngā tau matua, Hei tauira, he mata LCD tauira CLAA170EA02, tirohia te ripanga whakamāramatanga atanga i homai e te kaihanga, e kitea ana i roto i te pou poto i te reo Ingarihi, me RXO me RXE, kei ia hongere te tau "0" ~ "3" tohu raraunga rōpū, ā, kotahi te huinga tohu karaka (RXOC, RXEC rānei), e whakaatu ana tēnei he mata 30-pine, takirua, 8-bit te mata LCD, ehara hoki i te mea uaua ki te kite i tana mahi pine, arā, ko te "RXO0-" e tohu ana i te huinga tuatahi o ngā raraunga 1-, ko te tikanga o "RXO0 +" ko te huinga tuatahi o ngā raraunga: 1 +; Ko te "RXE0-" e tohu ana i te huinga tuarua o ngā raraunga 1-, ko te "RXE0 +" e tohu ana i te huinga tuarua o ngā raraunga 1 +, Ko te toenga, me ērā atu. Ko te atanga LVDS he kupu poto nō te reo Pākehā "Low Voltage Differential Signaling" e tohu ana i te tohu rerekētanga pēhanga-iti. Ka wikitoria te LVDS i ngā ngoikoretanga o te tuku i te whānui whānui i te whakamahinga hiko nui me te pokanoa hiko EMI i roto i te aratau taumata TTL, ā, he aratau tuku tohu ataata mamati. Ka whakamahia e te atanga putanga LVDS he nekehanga ngaohiko tino iti (tata ki te 350mV) hei tuku raraunga mā te rerekētanga i runga i ngā waea PCB e rua, i ngā taura taurite rānei. Ka tukuna e te atanga LVDS te tohu i runga i te PCB rerekētanga, i te taura taurite rānei i te tere o ngā rau megbits ia hekona. Nā te iti o te ngaohiko me te aratau taraiwa iahiko iti, he iti te haruru me te iti o te whakamahinga hiko. I roto i te pouaka whakaata tae LCD, ka whakamahia e te raina LVDS te taura taurite, he raina takirua miro. Ko te wāhanga ara iahiko atanga LVDS, arā, ko te pouaka whakaata tae LCD, ko te whakaaturanga tae rānei, ka wetewetehia tuatahitia ngā tohu whakauru (pēnei i te pouaka whakaata, te AV, me ētahi atu), kia whiwhi ai i te tohu RGB, he rite tonu te tukanga tukatuka ki te pouaka whakaata tae noa, kātahi ka tukuna mā te whakawhiti RGB-LVDS, te tohu LVDS putanga, ki te mata LCD. Nā te mea ko te tohu TTL (RGB) anake te tohu ka kitea e te TFT i roto i te mata LCD, me wetewete te tohu TTL e tukuna ana ki te mata LCD. Ka kitea ko te ara iahiko atanga LVDS kei roto i ngā wāhanga e rua: ko te ara iahiko atanga putanga LVDS i te taha papahoahoa (te tuku LVDS), me te ara iahiko atanga whakauru LVDS (te kaiwhiwhi LVDS) i te taha o te papa LCD. Ka hurihia e te pūwhakawhiti LVDS te tohu TTL ki te tohu LVDS, kātahi ka tukuna te tohu ki te IC wetewete LVDS i te taha o te papa LCD mā te taura rarangi, te taura ngāwari rānei i waenganui i te papa taraiwa me te papa LCD), ka hurihia te tohu raupapa ki te tohu whakarara o te taumata TTL, kātahi ka tukuna ki te mana wā LCD me te whakarārangi i te ara iahiko taraiwa.
