Yuav ua li cas "Outsider" paub qhov txawv ntawm cov teeb pom kev zoo coj? Nws tsis nkag siab meej LED tso ntxaij. Feem ntau, nws yog qhov nyuaj rau cov neeg siv los ntawm kev vam khom rau cov neeg ua haujlwm muag khoom tus kheej. Nov yog qee cov hau kev yooj yim los txheeb xyuas qhov zoo ntawm cov ntxaij vab tshaus tag nrho cov duab. Kuv vam tias nws yuav pab tau zoo thaum koj yuav cov ntxaij vab tshaus muaj xim puv ntoob.

Qhov zoo tshaj ntawm kev ntsuas LED Zaub LED Zaub LED tuaj yeem txiav txim siab los ntawm cov hauv qab no:

The surface flatness of the display screen must be within 1mm to ensure that the displayed image is not distorted Local protrusions or depressions will cause blind spots in the viewing angle of the display screen

1. Flatness

Lub tiaj tiaj ntawm cov zaub qhov screen yuav tsum nyob rau hauv ± 1mm kom ntseeg tau tias cov duab tso tawm kom muaj kev sib txawv. Hauv zos convxity los yog qhia meej yuav ua rau cov neeg dig muag hauv qhov pom ntawm lub kaum sab xis saib ntawm lub vijtsam zaub. Qhov sib txawv ntawm cov txee thiab tus qauv yuav tsum tsis pub dhau 1 hli. Yog tias qhov sib txawv yog loj heev, tus ciam ntawm cov zaub screen yuav pom tseeb thiab pom kev sib txuas lus yuav tsis sib xws. Qhov zoo ntawm cov tiaj tiaj tiaj yog tsuas yog txiav txim siab los ntawm cov txheej txheem ntau lawm.

2. Brightness thiab saib lub kaum ntse ntse

Qhov ci ntsa iab ntawm sab hauv cov tshuaj ntsuam muaj zog tag nrho yuav tsum yog qhov saum toj kawg nkaus 8000cd / m2 kom ntseeg tau tias qhov kev ua haujlwm ib txwm muaj ntawm cov zaub. Txwv tsis pub, cov duab tso tawm yuav tsis pom tseeb vim qhov ci qis. Qhov ci ci ntawm cov zaub screen tsis yog lub ci ntsa iab zoo dua, nws yuav tsum phim qhov ci ci ntawm lub LED pob. Ua kom muaj qhov tam sim no kom nce qhov ci ci yuav ua rau tus coj kom poob nws lub ci ci dhau thiab lub neej ntawm cov zaub vijtsam sai sai thiab yuav poob sai. Koj tuaj yeem nug cov chaw tsim khoom los muab cov ntawv tshaj tawm parameter kom paub meej tias. Lub ci ci ntawm lub vijtsam yog tsuas yog txiav txim siab los ntawm qhov zoo ntawm cov tub rog LED.

Qhov pom lub kaum ntse ntse hais txog qhov siab tshaj plaws ntawm qhov koj tuaj yeem pom tag nrho cov ntsiab lus screen los ntawm ob sab ntawm lub vijtsam. Qhov loj me ntawm lub saib lub saib ncaj qha txiav txim siab tus naj npawb ntawm cov neeg tuaj saib ntawm cov zaub screen, yog li qhov loj dua. Qhov pom kaum sab xis yuav tsum yog saum 150 degrees. Qhov loj me ntawm qhov pom lub kaum ntse ntse yog feem ntau txiav txim los ntawm cov ntawv ntim ntawm lub raj.

The brightness of the indoor full-color screen should be above 800cdm2 and the brightness of the outdoor full-color screen should be above 5000cdm2 to ensure the normal operation of the display screen Otherwise the

3. Cov nyhuv dawb

Cov nyhuv dawb yog ib qho ntsuas tseem ceeb tshaj plaws ntawm cov zaub hauv lub vijtsam zaub. Hauv kev tshawb fawb xim, cov xim dawb ntshiab yuav raug tso tawm thaum cov xim sib piv ntawm peb xim liab, ntsuab thiab xiav yog 1: 4.6: {3. Yog tias qhov tseeb tiag piv yog me ntsis deviated, yuav muaj kev sib txawv hauv qhov seem dawb. Feem ntau, kev saib xyuas yuav tsum tau them rau seb tus dawb yog xiav lossis daj-ntsuab. Thaum cov zaub yog monochrome, qhov me me ci thiab wavelength txawv ntawm LED, zoo dua. Thaum sawv ntawm sab ntawm lub vijtsam, tsis muaj xim txawv lossis xim pov cov xim, thiab kev sib xws yuav tsum yog qhov zoo. Qhov zoo ntawm kev tshuav dawb yog tsuas yog txiav txim siab los ntawm lub ci ci thiab wavelength ratio ntawm LED raj tseem ceeb ntawm lub vijtsam zaub. Lub raj txheem raj kuj cuam tshuam rau cov xim yug dua.

4. Cov xim luam menyuam
