Xav paub seb lub iav coj zaub yog dab tsi thiab nws ua haujlwm li cas? Tshawb nrhiav qhov kho qhov muag physics, RGB xim sib xyaw, thiab cov iav ntse ntse tom qab nws.
Taw qhia
Rau cov neeg soj ntsuam xws li, ib qho screen uas tam sim hloov los ntawm daim iav tsom mus rau lub ntsej muag digital zoo li ib yam dab tsi tawm ntawm cov yeeb yaj kiab science. To taub dab tsi ib daim iav coj zaub yog yuav tsum tau saib rau hauv kev sib xyaw ua ke ntawm cov khoom siv kho qhov muag thiab semiconductor engineering uas ua rau qhov kev hloov pauv no ua tau. Kab lus no rhuav tshem cov khoom siv sab hauv thiab cov qauv kev tshawb fawb uas tso cai rau ob lub hom phiaj no ua haujlwm tau zoo.
Optical Physics ntawm Ib -Txoj Kev Daim iav
Cov khawv koob ntawm cov thev naus laus zis no feem ntau yog nyob ntawm qhov tshwj xeeb pem hauv ntej iav vaj huam sib luag, uas ua raws li ib nrab -reflective lossis ib qho - daim iav.
Cov iav kho qhov muag no yog tsim los nrog ib qho tsis txaus ntseeg, ib nrab pob tshab txheej ntawm cov hlau, feem ntau yog txhuas lossis nyiaj, tso rau ntawm nws qhov chaw. Cov txheej no tso cai rau cov iav kom ua tiav qhov sib npaug ntawm kev xav thiab kev sib kis. Thaum lub teeb tsoo rau pem hauv ntej ntawm iav los ntawm chav ci ci, ib feem ntawm nws rov qab los, ua rau saum npoo zoo li daim iav txheem rau leej twg sawv ntawm nws xub ntiag.
Txawm li cas los xij, thaum lub teeb ci tom qab lub iav muaj zog dua li lub teeb pom kev ntawm sab hauv, lub teeb sab hauv dhau los ntawm semi- pob tshab txheej. Los ntawm kev tso lub siab - siv lub teeb pom kev zoo- emitting matrix ncaj qha tom qab lub substrate no, lub kaw lus tuaj yeem xaiv tawm ntawm chav tsev qhov kev xav, tso cai rau cov ntsiab lus digital kom pom meej hauv lub khob.
Tus kheej -Emissive LED Matrix
Tsis zoo li ib txwm LCD thev naus laus zis uas tso siab rau qhov tsis tu ncua, teeb pom kev zoo, cov tshuab no siv tus kheej -emissive LED qauv.
Hauv qhov kev teeb tsa no, txhua tus neeg pixel yog nws tus kheej lub teeb, ua los ntawm ib pawg me me ntawm liab, ntsuab, thiab xiav (RGB) diodes. Los ntawm kev sib xyaw cov hluav taws xob tam sim no xa mus rau txhua lub diode, lub pixel tuaj yeem tsim ntau lab ntawm cov xim sib txawv. Thaum lub pixel xav tau kom pom cov xim dub, nws tig tawm tag nrho.
Cov yam ntxwv no tseem ceeb heev rau daim iav tso saib. Thaum ib feem ntawm lub vijtsam pom cov xim dub, nws emits xoom lub teeb, uas txhais tau hais tias thaj chaw sib haum xeeb ntawm lub iav pem hauv ntej tseem ua haujlwm raws li daim iav ntshiab, tsis muaj kev cuam tshuam. Cov nyhuv ntab tshwm sim vim tias tsuas yog cov xim xim, lub teeb ci ntawm cov yeeb yaj kiab tawg los ntawm iav, thaum cov chaw tsaus nti tseem muaj kev cuam tshuam tag nrho.
Tswj System Architecture thiab teeb liab ua
Txhawm rau tso saib synchronized, cov ntsiab lus video kua dej, qhov pom kev pom nyob ntawm ntau-theem hluav taws xob tswj network.
Media Controller:Lub khoos phis tawj lossis huab -raws li media player uas tshaj tawm cov ntaub ntawv video lossis daim ntawv thov sib tham sib.
Xa daim npav:Ib qho kev tivthaiv uas ntes cov teeb liab video, resizes nws kom haum rau qhov tseeb pixel daws teeb meem ntawm cov zaub, thiab hloov nws mus rau hauv cov ntaub ntawv pob khoom.
Tau Txais Daim Npav:Nyob rau hauv lub chassis zaub, daim npav no txiav txim siab cov pob khoom tuaj thiab xa cov lus qhia meej rau tsav ICs.
Tsav ICs:Cov noICs(Integrated Circuits, uas yog microchips uas tswj cov hluav taws xob tam sim no ntws mus rau cov khoom siv hluav taws xob) tig tus kheej diodes rau thiab tawm ntau txhiab zaus hauv ib ob.
Core Technical Cheebtsam tawg
Txhawm rau kom nkag siab yuav ua li cas cov tshuab no tau muab tso ua ke, xav txog cov txheej txheem kho vajtse tseem ceeb uas pom nyob rau hauv cov qauv kev lag luam:
| Txheej / Txheej | Lub cev qhov chaw | Lub luag haujlwm tseem ceeb hauv System |

Cov ntsiab lus thiab cov lus pom zoo
Hauv cov ntsiab lus, daim iav coj zaub yog ib qho kev sib xyaw ua ke ntawm kev kho qhov muag physics thiab kev tsim khoom semiconductor siab heev. Los ntawm kev ua kom zoo dua ntawm ib qho - txoj kev iav thiab tus kheej - emissive xwm ntawm RGB pixels, cov ntxaij vab tshaus no tso saib cov ntsiab lus tiag tiag yam tsis tau poob lawv cov khoom ua haujlwm zoo.
Yog tias koj tab tom npaj yuav ib qho ntawm cov kab ke no, peb pom zoo kom nrhiav cov qauv uas siv siab - tsav ICs zoo nrog tus nqi tshiab. Qhov no tiv thaiv lub vijtsam los ntawm flickering thaum tib neeg thaij duab lossis yeeb yaj kiab ze ntawm daim iav, uas yog ib txwm muaj nyob rau hauv cov chaw muag khoom thiab cov rooj sib tham duab.
Cov lus nug nquag nug (FAQ)
Yuav ua li cas tshwm sim thaum cov zaub qhia ib daim duab dawb kiag li?
Thaum lub vijtsam pom cov duab dawb huv, tag nrho cov RGB diodes tau qhib ntawm lawv qhov kev siv siab tshaj plaws. Lub teeb hla lub iav yuav kov yeej lub ambient chav reflections, ua rau cov seem ntawm cov zaub kom zoo li tus qauv, ci digital screen uas tsis muaj daim iav pom.
Tus nqi transparency ntawm daim iav iav yog dab tsi?
Txawm hais tias feem pua ntawm qhov sib txawv ntawm cov chaw tsim khoom, cov iav kho qhov muag siv hauv cov lus qhia no feem ntau sib npaug kom tso cai rau ib feem ntawm lub teeb kom dhau mus thaum xav txog qhov seem. Qhov nyiaj tshuav no ua kom daim iav zoo li nkig thaum lub vijtsam kaw, tab sis cov ntsiab lus digital tseem pom meej thaum nws qhib.
Cov duab no puas xav tau cov ntaub ntawv video tshwj xeeb?
Txheem video tawm tswv yim zoo li MP4 lossis MOV yuav ua si zoo kawg nkaus. Txawm li cas los xij, kom tau txais txiaj ntsig zoo tshaj plaws, cov neeg tsim cov ntsiab lus feem ntau siv cov keeb kwm dub tob. Qhov no tawm hauv cov cheeb tsam dub uas muaj kev cuam tshuam tag nrho, ua rau cov xim xim lossis cov ntawv nyeem zoo li lawv ntab rau ntawm iav.
