Yuav ua li cas xam LED zaub Resolution, Loj & Saib nrug?

Kev xam cov kev daws teeb meem ntawm LED npo, qhov loj me, thiab saib qhov nrug muaj ntau yam xws li pixel suab, xav tau cov duab zoo, saib lub kaum sab xis, thiab cov neeg tuaj saib xav tau. Cia peb delve rau hauv txhua yam:

 

1. Kev daws teeb meem:

Kev daws teeb meem yog hais txog tus lej ntawm pixels suav nrog cov zaub. Nws ncaj qha cuam tshuam cov duab clarity thiab nthuav dav. Qhov kev daws teeb meem yog txiav txim siab los ntawm pixel suab thiab lub cev qhov ntev ntawm lub vijtsam.

 

Pixel Pitch:Pixel pitch yog qhov kev ncua deb ntawm cov chaw ntawm cov pixels uas nyob ib sab, feem ntau ntsuas hauv millimeters. Ib lub pixel me me txhais tau hais tias muaj kev daws teeb meem siab dua thiab cov duab zoo dua. Txhawm rau xam cov kev daws teeb meem, faib qhov dav thiab qhov siab ntawm lub vijtsam (hauv pixels) los ntawm pixel suab. Piv txwv li, yog tias ib qho screen yog 1920 pixels dav thiab 1080 pixels siab, thiab pixel suab yog 2 hli, qhov kev daws teeb meem yuav yog 960x540 pixels.

 

2. Loj:

Lub cev loj ntawm LED npo yog txiav txim siab los ntawm nws qhov ntev ntawm qhov dav thiab qhov siab. Qhov no yog qhov tseem ceeb rau kev txiav txim siab qhov chaw xav tau rau kev teeb tsa thiab ua kom lub vijtsam haum rau qhov chaw npaj.

 

3. Saib nrug:

Kev saib deb yog hais txog qhov deb npaum li cas cov neeg tuaj saib yuav nyob ntawm qhov screen. Nws cuam tshuam rau qhov kev daws teeb meem zoo tshaj plaws thiab qhov loj me kom ntseeg tau qhov kev pom zoo.

 

 

Kev xam pom qhov nrug:

 

Qhov pom qhov deb tuaj yeem xam raws li qhov pixel suab thiab qhov loj ntawm lub vijtsam. Ib txoj cai dav dav ntawm tus ntiv tes xoo yog qhov pom qhov deb yuav tsum yog tsawg kawg 1.5 npaug ntawm pixel suab rau kev pom zoo. Piv txwv li, yog tias pixel pitch yog 3 hli, qhov pom kev pom qhov deb yuav tsawg kawg yog 4.5 meters (1.5 * 3mm). Qhov no ua kom cov pixels ib leeg tsis pom, muab cov duab du thiab meej.

 

Factors yuav xav txog:

 

ib. Hom ntsiab lus:Cov ntsiab lus sib txawv yuav xav tau kev daws teeb meem sib txawv thiab saib qhov deb. Cov ntsiab lus video siab, piv txwv li, yuav tsum muaj kev daws teeb meem siab dua thiab saib ze dua kom txaus siab rau cov ntsiab lus.

 

b. Saib lub kaum ntse ntse:Xav txog lub kaum sab xis ntawm qhov screen yuav pom. Cov ntxaij vab tshaus tso rau ntawm lub kaum sab xis yuav xav tau kev daws teeb meem siab dua los tswj cov duab zoo rau cov neeg saib ntawm qhov siab sib txawv.

 

c. Cov neeg tuaj saib nyiam:Kev nkag siab txog kev nyiam thiab kev cia siab ntawm cov neeg tuaj saib yog qhov tseem ceeb. Qee cov neeg saib yuav ua qhov tseem ceeb ntawm cov duab meej, thaum lwm tus tuaj yeem ua qhov tseem ceeb ntawm qhov loj thiab qhov cuam tshuam tag nrho.

 

d. Environmental Factors:Ambient teeb pom kev zoo thiab ib puag ncig ib puag ncig tuaj yeem cuam tshuam cov duab pom zoo. Cov ntxaij vab tshaus tau teeb tsa hauv qhov chaw ci ntsa iab yuav xav tau ntau dua qhov ci ntsa iab kom tswj tau qhov pom.

 

e. Nyiaj txiag:Tus nqi ntawm lub vijtsam LED nce nrog kev daws teeb meem siab dua thiab qhov loj me. Kev ntsuas qhov xav tau tshwj xeeb nrog kev txwv nyiaj txiag yog qhov tseem ceeb rau kev ua tiav qhov kev daws teeb meem zoo.

 

 

Piv txwv Scenario:

 

Piv txwv tias koj tau ua haujlwm rau kev txhim kho lub vijtsam LED hauv lub rooj sib tham loj rau kev nthuav qhia thiab kev ua yeeb yaj kiab. Qhov kev ncua deb ntawm cov neeg tuaj saib mus rau qhov screen yog kwv yees li 20 meters. Txhawm rau kom pom qhov pom zoo, koj suav qhov xav tau kev daws teeb meem thiab qhov loj me:

 

Txiav txim siab Pixel Pitch: Raws li qhov kev ncua deb ntawm 20 meters thiab cov duab xav tau zoo, koj txiav txim siab ntawm pixel pitch ntawm 6mm.

 

Xam kev daws teeb meem: Yog tias qhov ntsuas qhov ntev yog 3840x2160 pixels, thiab pixel suab yog 6 hli, qhov kev daws teeb meem yuav yog 640x360 pixels.

 

Ntsuas Qhov Loj: Xav txog qhov loj ntawm lub tsev hais plaub thiab kev pom kev pom, koj txiav txim siab ntawm qhov screen loj ntawm 4 meters dav thiab 2.25 meters siab.

 

Los ntawm kev ua tib zoo xav txog cov xwm txheej no thiab kev suav, koj tuaj yeem xyuas kom meej tias lub vijtsam LED ua tau raws li qhov xav tau ntawm daim ntawv thov npaj thiab muab kev pom zoo rau cov neeg tuaj saib.
