Niaj hnub no, LCD advertising tshuab tau tawg txhua qhov chaw. Cov lag luam me thiab nruab nrab kuj tseem maj nrawm kom tau ib daim ntawm lub ncuav qab zib. Kev ua lag luam muaj cov kev xav tau siab dua thiab siab dua rau LCD zaub. Tom ntej no, Rongda Caijing cov kws tshaj lij yuav qhia koj cov duab tiag tiag ntawm cov tshuab luam ntawv LCD. Tam sim no.
Tsev tshaj tawm tshuab
Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis, kev ua tau zoo ntawm niaj hnub semiconductor lub teeb-emitting diodes tau mus txog qib tshiab, thiab nws cov kev hloov pauv photoelectric tau mus txog ntau dua 10cd / w. Tshwj xeeb tshaj yog qhov tshwm sim ntawm xiav ultra-ci LED li ua rau lub spectrum ntawm LED li npog qhov ntau ntawm lub teeb ntuj. .
Lub hauv paus ntsiab lus ntawm kev pom ntawm cov xim puv LCD advertising tshuab zaub yog tib yam li cov xim TV. Nws paub txog kev kho dua tshiab thiab kev tsim tawm ntawm cov duab xim los ntawm qhov sib txawv ntawm lub teeb siv ntawm peb xim liab, ntsuab thiab xiav. Lub purity ntawm liab, ntsuab thiab xiav ncaj qha cuam tshuam qhov pom kev ntawm cov duab xim luam tawm. Txawm li cas los xij, peb-xim piv ntawm lub teeb dawb tsis yog ib qho yooj yim superposition ntawm peb xim.
Ua ntej, nyob rau hauv lub premise ntawm kev ua kom lub purity ntawm lub optical zaus, qhov piv ntawm qhov siv ntawm lub teeb liab, ntsuab thiab xiav yuav tsum nyob ze rau 3: 6: 1;
Qhov thib ob, vim qhov kev xav ntawm tib neeg lub zeem muag rau liab, lub teeb liab yuav tsum tau tawg mus rau hauv qhov chaw;
Thib peb, vim yog qhov sib txawv ntawm qhov tsis sib txawv ntawm cov lus teb ntawm tib neeg lub zeem muag rau lub teeb siv ntawm peb xim liab, ntsuab thiab xiav, nws yuav tsum tau kho lub teeb dawb nrog lub teeb sib txawv ntawm lub teeb yuav tsum tau kho rau liab, ntsuab thiab xiav zoo ib yam li gamma. kho hauv TV teeb;
Plaub, tib neeg lub zeem muag tsis muaj peev xwm paub qhov txawv chromatic aberration. Yog li ntawd, nws yog ib qho tsim nyog yuav tau nrhiav lub hom phiaj ntsuas qhov tseeb ntawm cov duab xim luam tawm.
Yuav kom rov tsim cov duab tiag tiag xim, lub teeb tis ntawm LCD advertising tshuab zaub yuav tsum ua raws li cov hauv qab no:
① Lub wavelengths ntawm liab, ntsuab thiab xiav yuav tsum yog hais txog 660nm, 525nm thiab 470nm feem;
② Nws yog qhov zoo dua los siv 4-tube chav tsev nrog lub teeb dawb (ntau lub raj kuj ua tau, nyob ntawm qhov siv lub teeb);
③ theem grey ntawm liab, ntsuab thiab xiav yog 256 qib;
④ Tsis-linear kho rau LED pixel raj yuav tsum tau txais yuav.
Lub teeb liab, ntsuab thiab xiav lub teeb faib thiab kev kho uas tsis yog-linear tuaj yeem pom tau los ntawm kev kho vajtse ntawm cov khoom siv tswj hwm lossis los ntawm software ntawm playback system.
