Yuav ua li cas ib tug layman paub qhov zoo ntawm LED zaub? Feem ntau, nws yog ib qho nyuaj rau convince tus neeg siv raws li tus neeg muag khoom qhov kev txiav txim rau tus kheej. Muaj ob peb txoj hauv kev yooj yim los txheeb xyuas qhov zoo ntawm tag nrho cov xim LED zaub screen.
1. Flatness
Qhov chaw tiaj tus ntawm lub vijtsam LED yuav tsum nyob hauv ± 0.1mm kom ntseeg tau tias cov duab pom tsis txawv txav. Ib nrab protrusions los yog recesses yuav ua rau lub kaum sab xis tuag nyob rau hauv lub kaum sab xis saib ntawm LED zaub screen. Nruab nrab ntawm LED txee thiab LED txee, qhov sib txawv ntawm lub module thiab module yuav tsum tsis pub dhau 0.1 hli. Yog tias qhov sib txawv loj dhau lawm, ciam teb ntawm LED zaub screen yuav pom tseeb thiab lub zeem muag yuav tsis sib koom ua ke. Qhov zoo ntawm flatness yog tsuas yog txiav txim los ntawm cov txheej txheem ntau lawm.
2. Kev ci ntsa iab
Lub brightness ntawmsab hauv tsev LED npoyuav tsum siab tshaj 800cd/m2, thiab lub brightness ntawm lubsab nraum zoov LED zaubyuav tsum siab tshaj 5000cd/m2 kom pom cov nyhuv ntawm lub vijtsam LED, txwv tsis pub cov duab tso tawm yuav tsis meej vim qhov ci ntsa iab tsawg dhau. Qhov ci ntsa iab ntawm LED zaub screen tsis ci li qhov ua tau, nws yuav tsum phim qhov ci ntawm lub pob LED. Qhov muag tsis pom kev nce qhov tam sim no kom qhov ci ntsa iab yuav ua rau LED txo qis sai heev, thiab lub neej ntawm LED zaub yuav txo qis sai. Lub ci ci ntawm LED zaub yog tsuas yog txiav txim siab los ntawm qhov zoo ntawm LED teeb.
3. Saib lub kaum sab xis
Lub kaum sab xis saib yog hais txog lub kaum sab xis siab tshaj plaws uas koj tuaj yeem pom tag nrho LED npo cov ntsiab lus los ntawm LED video screen. Qhov loj ntawm lub kaum sab xis saib ncaj qha txiav txim siab rau cov neeg tuaj saib ntawm lub vijtsam LED, yog li qhov loj dua qhov zoo, lub kaum sab xis saib yuav tsum yog ntau tshaj 150 degrees. Qhov loj ntawm lub kaum sab xis saib yog tsuas yog txiav txim siab los ntawm txoj kev ntim ntawm LED teeb.
4. Dawb tshuav nyiaj li cas
Dawb tshuav nyhuv yog ib qho tseem ceeb tshaj plaws qhia ntawm LED zaub. Nyob rau hauv cov nqe lus ntawm cov xim, dawb huv yuav tshwm sim thaum tus piv ntawm peb thawj xim ntawm liab, ntsuab thiab xiav yog 1: 4.6: 0.16. Yog tias muaj qhov sib txawv me ntsis hauv qhov sib piv tiag tiag, yuav muaj qhov sib txawv ntawm qhov sib npaug dawb. Feem ntau, nws yog ib qho tsim nyog yuav tau them sai sai rau seb cov dawb yog xiav lossis daj. ntsuab tshwm sim. Hauv monochrome, qhov me me qhov sib txawv ntawm qhov ci thiab wavelength ntawm LEDs, qhov zoo dua. Tsis muaj xim sib txawv lossis xim cam thaum sawv ntawm sab ntawm lub vijtsam, thiab qhov sib xws zoo dua. Qhov zoo ntawm qhov nyiaj tshuav dawb yog txiav txim siab los ntawm qhov sib piv ntawm qhov ci thiab wavelength ntawm LED teeb thiab kev tswj hwm ntawm LED zaub screen.
5. Xim reducibility
Xim reducibility yog hais txog cov xim uas tshwm rau ntawm LED zaub yuav tsum tau ua tib zoo sib xws nrog cov xim ntawm qhov chaw playback, thiaj li ua kom cov duab tseeb.
6. Seb puas muaj mosaic thiab qhov chaw tuag tshwm sim
Mosaic hais txog cov squares me me uas ib txwm ci lossis ib txwm dub ntawm LED zaub, uas yog qhov tshwm sim ntawm module necrosis. Qhov laj thawj tseem ceeb yog vim li cas qhov zoo ntawm IC los yog lub teeb hlaws siv hauv LED zaub tsis zoo. Tuag taw tes yog hais txog ib qho taw tes uas ib txwm ci lossis ib txwm dub ntawm LED zaub. Tus naj npawb ntawm cov ntsiab lus tuag feem ntau yog txiav txim siab los ntawm qhov zoo ntawm qhov tuag thiab seb cov chaw tsim khoom siv los tiv thaiv zoo li qub yog zoo meej.
7. Nrog lossis tsis muaj xim thaiv
Xim thaiv yog hais txog qhov pom tseeb xim sib txawv ntawm cov modules uas nyob ib sab. Kev hloov xim yog nyob ntawm qhov module. Cov xim thaiv qhov tshwm sim feem ntau yog tshwm sim los ntawm kev tswj tsis zoo, qib qis qis thiab qis scanning zaus.
8. Zaub stability
Stability yog hais txog kev txhim khu kev qha zoo ntawm LED zaub hauv cov kauj ruam laus tom qab nws tiav lawm.
9. Kev ruaj ntseg
LED zaub yog tsim los ntawm ntau lub txee LED, txhua lub txee LED yuav tsum tau muab tso rau hauv av, thiab cov av tiv thaiv yuav tsum tsawg dua 0.1 ohms. Thiab tuaj yeem tiv taus qhov hluav taws xob siab, 1500V 1min yam tsis muaj kev puas tsuaj. Cov cim ceeb toom thiab cov lus tshaj tawm yuav tsum muaj nyob rau ntawm lub tshuab hluav taws xob high-voltage input thiab cov xaim hluav taws xob siab ntawm lub zog hluav taws xob.
10. Ntim thiab Shipping
LED zaub screen yog ib qho khoom muaj txiaj ntsig nrog qhov hnyav loj, thiab cov txheej txheem ntim khoom siv los ntawm cov chaw tsim khoom tseem ceeb heev. Feem ntau, nws tau ntim rau hauv ib lub txee LED, thiab txhua qhov chaw ntawm LED txee yuav tsum muaj cov khoom tiv thaiv kom tsis txhob muaj teeb meem, yog li ntawd lub LED muaj qhov chaw me me rau kev ua haujlwm sab hauv thaum thauj.
