kua siv lead ua kua

Oct 19, 2017

thaum ntxov xws li hauv xyoo 1888, tib neeg yuav nrhiav tau cov kua ua kua ua kua, xws li lub tshuab hlau nplua hlau, nrog rau kev siv hluav taws xob sab nraud thaum cov neeg phem yuav ua kom muaj kev sib haum xeeb. Yog hais tias qhov kev npaj ntawm cov khoom tsim nyog tsim nyog, kua crystal molecules yuav tso cai los ntawm. Nyob rau hauv txheej txheej kawg nkaus yog cov khoom siv fluorescent los ntawm kev sib txuas ntawm lub teeb los ntawm nws cov txheej txheem. Ib txheej ntawm lub teeb backlighting los ntawm thawj txheej polarization filtering txheej rau hauv muaj tom qab kaum ntawm txhiab tus siv lead ua kua kua siv lead ua. Ua kua dej qab ntsev txheej ntawm crystalline mob yog nyob hauv lub pob zeb me me, ib los yog DuoGe ntawm tes los ua ib qho pixel ntawm qhov screen. Thaum cov kua siv lead ua los ntawm electrode khoom hluav taws xob, cov kua siv lead ua kua yuav ua rau muaj kev sib ntxub, uas yuav yog ib lub teeb los ntawm kev xav txog cov cai, thiab tom qab ntawd tom qab zaum ob lim dej lim ntawm qhov screen, uas yog lub tshuab tso digital LCD. Cov kua Crystal Display (LCD) Lus Askiv Ua Kua Crystal Display tag nrho hu ua, yog ib yam ntawm cov tshuab siv digital, muaj peev xwm los ntawm Cov Kua Crystal thiab xim lim teeb ci, hauv cov duab vaj huam sib luag tsim duab. Nws yog ib hom siv LCD tswj tag nrho cov cuab yeej siv kom pom cov xim xim. Dej siv lead ua kua yog lub hwj huam siv tsawg heev ntawm cov khoom ntaus. Hauv hnab tshos los siv ntau dua. Kev siv tshuab ua kua ua kua yog tsim tawm sai sai nyob rau hauv xyoo tas los, txhua yam ntawm LCD cov chav kawm ntawv ntawm ntau, nws tus tshwj xeeb tsav nti kuj sib txhawb, ua LCD hauv kev tswj system yog dav siv nyob rau hauv lo lus ntawm lub rooj muab zoo heev. Txhua yam ntawm LCD cov chav kawm ntawv ntawm ntau tus neeg, nws tus tshwj xeeb nti nti kuj sib txhawb, ua LCD hauv kev tswj qhov siv dav siv lo lus ntawm lub rooj muab tau yooj yim heev. LCD yuav muab faib ua ib hom LCD, hom cim LCD thiab teev nti LCD. Ntawm lawv, tib hom LCD thiab cov ua cim hom LCD tsuas yog siv rau cov cim thiab Cov zauv yooj yim, thiab tsis tuaj yeem ua tau teeb thiab suav pom yam yuav tsum tau ua; Thiab teev matrix LCD tsis tuaj yeem tso saib cov cim, Cov zauv, tuaj yeem tso tau txhua yam ntawm cov duab kos, cov duab kos thiab cov cim, thiab paub muaj peev xwm paub txog qhov nce thiab nqis los yog li ntawd dov, ua haujlwm animation, muab faib qhov rai, rov qab, eeb, thiab lwm yam functions, siv ntau heev. Tom qab 20 Kev tshawb fawb DuoNian, kev sib tw thiab kev txhim kho, kev vaj huam sib luag rau kev lag luam tau nkag lub luag haujlwm hauv lub xyoo tshiab, ua cov ntsiab lus ntawm cov khoom muag, tam sim no cov kev sib tw ntawm cov vaj huam sib luag tiaj tus muaj plaub hom:

(1) field-emission ca vaj huam sib luag (FED)

(2) plasma ca cov vaj huam sib luag (PDP)

(3) cov yeeb yaj kiab organic electroluminescent (OEL)

(4) thin film transistor LCD tiaj tus vaj huam sib luag zaub (tft-lcd)

LCD tiab pav ca, tshwj xeeb tft-lcd, tsuas yog ib qho hauv lub ci ci, qhov sib piv, kev siv fais fab thiab lub neej, ntim thiab qhov hnyav kev ua haujlwm hauv ib txoj kev txhuas kom dhau nrog thiab ntau tshaj CRT zaub ntaus ntawv, nws qhov ua tau zoo , qhov khoom loj zuj zus tuaj, muaj kev kawm siab, cov khoom nyhav qis, qis rau chav loj hlob, lub xyoo pua tshiab yuav pib ua khoom loj, yog 21st century lub ntiaj teb kev loj hlob ntawm lub qhov rais.

Qhov kev tsim no yog qhov kev tshawb nrhiav hauv AT89S51 dot-matrix LCD monitor ACM12864 thiab ib lub voj voog microcomputer interface thiab qhov haujlwm ntawm qhov chaw ntawm lub cajmeem, kom paub cov kev cai ntawm kev ua haujlwm, muaj zog tiv thaiv kev ua haujlwm, kev ruaj ntseg. Qhov kev tsim cov qauv no yog AT89S51 series microcontroller li cov tub ntxhais ntawm cov kua siv coj los ua kua (LCD), thiab qhia txog qhov tseem ceeb, cov txheej txheem nris txheej txheem, cov tswv yim tsim thiab kev ua haujlwm software. Txuas rau pem hauv ntej ib qho cuab yeej ua tau raws li tus qauv ntawm cov npo LCD raws li ib qho kev sib txuas ntawm lub tshuab hlwb hlau microcomputer tsim, thiab muab lub tshuab hluav taws xob hauv nruab nrab ntawm microcontroller thiab software raws li, thiab raws li kev xaiv ntawm ib qho ntawm ib qho me me chip microcomputer, kev tsim kho vajtse thiab cov qauv software, cov lus sib dhos lus thiab cov ncauj lus kom ntxaws.
