Cov tsav tsheb npav tsav npav LCD feem ntau hu ua A / D (analog / digital) pawg thawj coj, uas nyob rau hauv kev txiav txim zoo qhia lub luag haujlwm tseem ceeb ntawm pawg tsav tsheb. Txhawm rau tso cov duab ntawm LCD npo, yuav tsum muaj ib lub teeb liab video yuav tsum muaj. Pawg tsav tsheb LCD yog cov txheej txheem ua haujlwm uas ua tiav kev hloov pauv los ntawm cov teeb liab sib piv rau cov teeb liab digital (lossis los ntawm ib lub cim hluav taws xob mus rau lwm lub teeb liab digital), thiab tib lub sijhawm hauv cov duab tswj chaw tswj tau nqis los tsav lub LCD screen rau tso saib duab.
LCD tsav board feem ntau muaj lub ntsiab tswj nti, MCU microcontroller, ROM nco, fais fab module, fais fab interface, VGA video teeb liab tawm tswv yim interface, OSD pawg thawj coj saib interface, high voltage board interface, LVDS / TTL tsav screen teeb liab interface thiab lwm yam.
Lub hauv paus ntsiab lus ntawm LCD screen tsav tsheb board Lub teeb liab video xa los ntawm daim npav tso saib ntawm lub koos pij tawj lub computer yog xa mus rau lub ntsiab tswj nti ntawm lub rooj tsav tsheb los ntawm VGA video teeb liab tawm tswv yim kev cuam tshuam ntawm cov tsav tsav. Lub hauv paus tswj tseem ceeb yog nyob ntawm cov ntaub ntawv hais txog cov tshuaj ntsuam LCD hauv MCU microcontroller. Tswj lub vijtsam LCD los qhia cov duab. Tib lub sijhawm, MCU microcontroller paub txog kev tswj lub zog thiab ua haujlwm ntawm lub tshuab tag nrho. Yog li no, tus tsav tsheb LCD tseem hu ua LCD motherboard.
Yog tias LCD tsav lub rooj tsav xwm puas ntsoog, nws yuav ua rau ua tsis tiav xws li tsis ua haujlwm khau raj, lub vijtsam dub, vijtsam dawb, plooj plooj npo, cuam tshuam kev cuam tshuam, thiab khawm tsis ua haujlwm, uas suav nrog qhov loj ntawm LCD tsis ua haujlwm.
Kev sib xyaw sib xyaw loj thiab cov khoom siv hauv chip tau dav siv hauv cov tsav tsheb tsav hauv LCD, thiab cov txheej txheem ntawm cov khoom siv hauv Circuit Court yog qhov uas tsis sib thooj, uas ua rau nws nyuaj nrhiav cov khoom tshwj xeeb lossis cov kab khiav. Nyob rau hauv cov xwm txheej tsis-lub Hoobkas, nws qhov rov kho dua yog qhov tsawg. Yog tias lub rooj tsav tsheb tsis xwm yeem vim kev puas tsuaj rau lub zog mov thiab VGA video input interface Circuit part, ntev npaum li peb muaj kev paub hauv Circuit Court, peb tuaj yeem daws nws yooj yim. Rau cov uas tshwm sim los ntawm sab hauv MCU microcontroller Cov ntaub ntawv puas tsuaj los ntawm pawg tsav tsheb tsis tuaj yeem ua haujlwm ib txwm. Nyob rau hauv qhov ua ntej ntawm muaj cov ntaub ntawv cov ntawv (tsav tsheb), peb tuaj yeem siv LCD programmer los tswj hwm MCU microcontroller los kho cov kev ua tsis zoo los ntawm cov khoom siv firmware puas tsuaj. Hauv cov tsav tsheb thaum ntxov, nws yog qhov tsim nyog yuav tsum tawg ntawm MCU microcontroller rau kev ua haujlwm, uas yog qhov nyuaj heev. Cov tsav tsheb tam sim no feem ntau pib siv MCU microcontrollers uas txhawb ISP (Online Programming), yog li peb tuaj yeem npaj cov ntaub ntawv hauv MCU microcontroller online los ntawm ISP cov cuab yeej. Piv txwv, dot screen driver version ntawm 814-50-5 peb siv yog qhov tseeb LCD saib uas tuaj yeem ua tiav hom haujlwm no.
Hauv kev saib xyuas ntawm LCD saib, thaum cov tsav tsheb tsav tsis, yog hais tias LCD saib thaum chiv thawj siv cov tsav dav dav tsav dav dav, koj tuaj yeem nrhiav ncaj qha rau lub motherboard coj los hloov. Tau kawg, koj tseem yuav tsum tau sau rau hauv MCU thiab LCD tshuaj ntsuam. Sib ntsib tus tsav tsheb; yog hais tias lub rooj tsav tsheb yog hom muaj npe niam xov tooj, peb feem ntau siv cov" chaw tsav dav dav" ntawm kev ua lag luam los hloov nws rau kev tswj kho;
& quot; Pawg tsav tsheb tsav thoob ntiaj teb" tseem hu ua" tsav dav hlau thoob ntiaj teb" ;. Tam sim no, muaj ntau ntau hom ntawm" chav tsav dav dav" nyob rau kev ua lag luam. Txawm hais tias cov khoom siv coj los siv hauv no" universal tsav pawg" muaj qhov tsis sib haum nrog" thawj tsav lub rooj tsav", ntev li ntev tau lub koos pij tawj siv los sau LCD rau hauv" tsav dav tsav" Qhov kev pabcuam tsav tsheb sib thooj rau lub vijtsam (lub vijtsam LCD tsav tsav CD yuav xa thaum koj yuav tus programmer), thiab tom qab ntawd koj tuaj yeem tsav cov duab LCD sib txawv los ntawm kev hloov cov xov hlau. Nws muaj lub zog ntau yam, thiab tus nqi tu yog tsis siab. Nws yog qhov yooj yim rau cov neeg siv txais.
Txij li ntawm LCD screen muaj ntau lub teeb liab cuam tshuam, tseem muaj ntau lub teeb liab kab (TTL / LVDS teeb liab kab) nruab nrab ntawm cov tsav tsheb tsav dav dav thiab cov tshuaj ntsuam LCD.
Siv cov" tsav npav tsav dav dav" los hloov cov tsav tsheb LCD tsav hauv peb kauj ruam: tshuaj ntsuam, kab hloov, thiab teeb tsa.
Shenzhen Yongsheng Innovation Technology Co., Ltd.' s cov khoom tseem ceeb yog: LCD tsom kwm, LCD cov ntxaij vab tshaus, LCD nti, cov khoom lag luam, cov khoom siv kho mob, cov chaw tsav tsheb, cov thawj cov laj thawj, thiab lwm yam.
