1. Xim Chaw Hloov Tshuab
LEDtso saibxim qhov chaw hloov dua siab tshiab tshuab yog ib qho ntawm cov thev naus laus zis tseem ceeb ntawm cov txheej txheem video. Cov ntxaij vab tshaus LED sib txawv siv cov xim sib txawv, yog li nws yog qhov tsim nyog los hloov cov teeb liab tawm tswv yim rau hauv qhov chaw xim uas phim lub vijtsam LED los ntawm xim qhov chaw hloov tshuab. Tam sim no, feem ntau siv xim qhov chaw yog RGB, YUV thiab YCbCr, thiab lwm yam. Los ntawm cov xim qhov chaw hloov dua siab tshiab technology, cov xim sib txawv tuaj yeem hloov mus rau qhov chaw xim ntawm LED npo, thiaj li ua tiav cov xim luam tawm.
2. Duab Enlargement Technology
Qhov kev daws teeb meem ntawm lub suab me me LED npo yog siab heev, thiab cov duab amplification thev naus laus zis yog ib qho ntawm cov thev naus laus zis tseem ceeb ntawm cov txheej txheem video. Duab magnification tshuab feem ntau suav nrog interpolation algorithm, magnification algorithm thiab ntug preservation algorithm. Interpolation algorithm yog ib qho ntawm feem ntau siv cov duab o tshuab, los ntawm cov interpolation algorithm tuaj yeem ua cov duab tsis tshua muaj siab rau cov duab loj loj, txhim kho qhov pom tseeb thiab nthuav dav ntawm daim duab.
3.Color Correction Technology
Kev kho xim tshuab yog ib qho tseem ceeb heev technology nyob rau hauv lub LED screen video processor, vim hais tias lub screen LED nyob rau hauv lub manufacturing txheej txheem yuav inevitably tshwm sim ib co chromatic aberration, tshwj xeeb tshaj yog nyob rau hauv lub splicing yog ntau prone rau chromatic aberration. Kev kho xim thev naus laus zis feem ntau yog los ntawm qhov sib piv, saturation, xim thiab lwm yam tsis tau hloov kho kom ua tiav cov xim sib npaug thiab sib npaug, txhim kho cov xim luam ntawm cov yeeb yaj kiab.
4. Grey Scale Processing Technology
Me pitch LED npo nyob rau hauv cov zaub ntawm grey scale yuav tsum muaj siab heev, yog li greyscale ua technology kuj yog ib tug ntawm cov tseem ceeb technologies nyob rau hauv lub video processor. Grey scale processing thev naus laus zis yog los ntawm PWM (Pulse Width Modulation) thev naus laus zis los tswj qhov ci ntsa iab ntawm LED, kom lub ci ci ntawm txhua lub LED tuaj yeem raug kho kom raug. Nyob rau tib lub sijhawm, cov txheej txheem ua haujlwm grey kuj xav tau los daws qhov teeb meem ntawm cov lej tsis txaus ntawm qib grey kom ua tiav cov duab qhia ntxaws ntxiv.
5. Pretreatment Technology
Pre-processing thev naus laus zis hais txog kev ua haujlwm thiab kev ua kom zoo ntawm cov teeb liab video ua ntej LED npo zaub. Nws feem ntau suav nrog cov teeb liab nce, denoising, sharpening, filtering, xim li thiab lwm yam kev ua. Cov kev kho mob no tuaj yeem txo cov suab nrov, txhim kho qhov sib piv thiab pom meej thaum xa cov cim, thaum tseem tshem tawm cov xim sib txawv thiab txhim kho qhov tseeb thiab nyeem tau ntawm cov duab.
6. Ncej Synchronization
Hauv cov zaub ntawm LED npo, thav duab synchronization thev naus laus zis kuj yog ib qho ntawm cov thev naus laus zis tseem ceeb hauv video processor. Ncej synchronization thev naus laus zis yog ua tiav los ntawm kev tswj hwm tus nqi refresh ntawm lub vijtsam LED thiab tus ncej tus nqi ntawm cov teeb liab tawm tswv yim, kom lub vijtsam video tuaj yeem pom zoo. Hauv multi-screen splicing, thav duab synchronization thev naus laus zis tuaj yeem zam qhov sib txawv ntawm qhov screen flicker thiab tearing thiab lwm yam teeb meem.
7.Display Delay Technology
Lub sijhawm ncua sij hawm ntawm lub vijtsam me me ntawm LED yog qhov tseem ceeb heev vim tias hauv qee qhov kev siv, xws li E-Sports kev sib tw thiab kev hais kwv txhiaj, lub sijhawm ncua ntev tuaj yeem ua rau video thiab suab tsis sib xws, uas cuam tshuam rau cov neeg siv kev paub. Yog li ntawd, video processors yuav tsum tau nruab nrog zaub ncua tshuab kom ua tiav lub sij hawm ncua sij hawm luv tshaj.
8.Multi-signal Input Technology
Qee lub sij hawm, nws yog ib qho tsim nyog los tso saib ntau qhov chaw teeb liab tib lub sijhawm, xws li ntau lub koob yees duab, ntau lub khoos phis tawj thiab lwm yam. Yog li ntawd, video processor yuav tsum muaj ntau lub teeb liab input technology, uas tuaj yeem tau txais ntau qhov chaw teeb liab nyob rau tib lub sijhawm, thiab hloov thiab sib xyaw cov zaub. Nyob rau tib lub sijhawm, ntau lub teeb liab tawm tswv yim thev naus laus zis kuj yuav tsum tau daws cov teeb meem ntawm cov teeb liab sib txawv ntawm qhov kev daws teeb meem thiab cov qauv sib txawv kom ua tiav cov yeeb yaj kiab ruaj khov thiab du.
Hauv cov ntsiab lus, cov thev naus laus zis tseem ceeb ntawm lub suab me me LED screen video processor suav nrog cov xim qhov chaw hloov pauv tshuab, duab nthuav dav, xim kho tshuab, grey nplai ua tshuab, thav duab synchronization tshuab, tso saib qeeb tshuab thiab ntau lub teeb liab input technology. Kev siv cov thev naus laus zis no tuaj yeem txhim kho cov txiaj ntsig zoo thiab cov neeg siv kev paub ntawm lub suab me me LED npo. Nyob rau hauv lub neej yav tom ntej, nrog kev txhim kho txuas ntxiv ntawm thev naus laus zis, video processor yuav raug hloov kho tas li thiab txhim kho rau daim ntawv thov me me suab LED npo kom ua tau zoo dua.
