Tus ncej tus nqi ntawm LED lub rooj sib tham zaub screen yog ib qho tseem ceeb parameter cuam tshuam nws stability thiab smoothness. Cov hauv qab no piav qhia txog nws cov ntsiab lus, cuam tshuam rau cov xwm txheej, cov lej ntau, thiab cov txiaj ntsig siv tau:
Lus Txhais thiab Lub Luag Haujlwm ntawm Tus Qauv Ncej: Tus ncej tus nqi yog hais txog tus naj npawb ntawm lub sijhawm cov ntaub ntawv ntawm lub rooj sib tham LED zaub screen yog hloov kho rau ib chav tsev ntawm lub sijhawm, piv txwv li, tus lej sib law liag tso tawm ib ob. Qhov tseem ceeb, nws yog qhov ceev ntawm cov ntsiab lus dynamic ntawm qhov screen refreshes, ncaj qha cuam tshuam rau kev pom kev pom:
Smoothness: Ib tus ncej siab dua ua rau cov duab hloov pauv ntau dua, txo qis stuttering lossis ghosting. Thaum ib qho chaw pib mus txog (piv txwv li, siab dua 60Hz), tib neeg lub qhov muag pom tau cov duab tsis tu ncua es tsis yog cov duab sib txawv.
Stability: Tus ncej tus nqi yog muaj zog correlated nrog system stability. Tsawg- zaus hloov tshiab tuaj yeem ua rau lub vijtsam flickering lossis tearing, tshwj xeeb tshaj yog thaum hloov cov ntsiab lus nrawm (piv txwv li, PPT nplooj tig, video playback).
Factors Determining Frame Rate: LED qhia tawm lub teeb los ntawm qhov tam sim no ntws los ntawm pixels. Qhov ceev tam sim no cuam tshuam ncaj qha rau lub sijhawm teb pixel. Tsis tshua muaj kev sib kis tau zoo tam sim no nce qhov ncua sij hawm hauv pixel rau / tawm, txwv tus ncej tus nqi.
Hais Txog Lub Sijhawm thiab Kev Tshaj Tawm (DCLK)
Lub Sijhawm Chaw Nyob: Lub sijhawm xav tau rau lub kaw lus nrhiav thiab qhib lub pixel tshwj xeeb. Lub sij hawm hais luv luv tso cai rau cov thav ntawv ntau dua los hloov kho ib chav tsev ntawm lub sijhawm.
Transmission Frequency (DCLK): Cov ntaub ntawv moos zaus, txiav txim siab tus nqi ntawm cov ntaub ntawv xa mus rau cov zaub ib ob. DCLK siab dua ua rau muaj kev hais lus ntau dua thiab muaj peev xwm ntau dua qhov hloov pauv zaus.
Kev sib raug zoo: Kev hais txog lub sijhawm thiab DCLK ua ke txwv tsis pub tus ncej hloov zaus. Piv txwv li, yog tias lub sijhawm hais lus yog 1ms thiab DCLK yog 100MHz, lub theoretical thav duab hloov zaus tuaj yeem ncav cuag 1000Hz (tseem txwv los ntawm kev tsim qauv).
Kev tsim qauv tsim kom zoo suav nrog kev tsav tsheb nti, kev teeb tsa hauv Circuit Court, thiab kev tsim hluav taws xob tawg. Cov tshuab ua haujlwm tau zoo tuaj yeem txo cov teeb liab kis tau tus mob ncua sij hawm thiab ua rau muaj kev txwv sab sauv ntawm tus ncej hloov zaus.
Ncej Switching zaus ntau thiab kev lag luam Standards
Qhov Pib Pib: Cov vaj huam sib luag tiaj tus feem ntau muaj cov nqi tshiab siab dua 75Hz kom tsis txhob pom qhov flickering. LED lub rooj sib tham qhia, raws li cov khoom siv dynamic, yuav tsum tau ua kom tau raws li cov qauv siab dua.
Mainstream Product Parameters:
Nkag mus-level: 60-120Hz, haum rau cov ntsiab lus zoo li qub lossis cov xwm txheej tsis tshua muaj zog.
High-cov khoom kawg: 240Hz lossis siab dua, txhawb siab - video ceev, games, lossis tiag- cov ntaub ntawv sib cuam tshuam sijhawm.
Kev suav cov qauv: Cov nqi rov qab tshiab=Kab rov tav Synchronization Scan kab × Ncej tus nqi. Piv txwv li, yog tias kab rov tav scan kab yog 1080 thiab tus ncej tus nqi yog 120Hz, ces tus nqi refresh yog 129,600Hz (nco ntsoov tias qhov no yog tus nqi theoretical; qhov tseeb refresh npaum li cas yuav tsum xav txog qhov hais txog lub sijhawm poob).
Qhov cuam tshuam tiag tiag ntawm Ncej tus nqi ntawm cov neeg siv kev paub
Visual Comfort
Tsawg zaus (<60Hz): The image may flicker or jitter, easily causing eye fatigue during prolonged viewing.
High Frequency (Ntau dua los yog sib npaug rau 120Hz): Cov ntsiab lus dynamic (xws li lub cim txav, cov ntaub ntawv scrolling) yog smoother, txo kiv taub hau.
Cov ntsiab lus Adaptability
Static Display: Tsawg zaus txaus, tab sis kev ruaj ntseg yuav tsum tau tswj kom tsis txhob pom qhov muag plooj / duab npoo.
Dynamic Scenes: Siab - zaus hloov pauv kom ntseeg tau qhov tseeb ntawm cov yeeb yaj kiab thiab cov ntsiab lus animation, tsis txhob muaj dab los yog kua muag.
High system compatibility yuav tsum tau tus ncej tus nqi kom phim cov zis ncej tus nqi ntawm input qhov chaw (xws li, computer, koob yees duab). Yog tias lub teeb liab tawm tswv yim yog 30Hz, txawm tias cov zaub txhawb 240Hz, qhov tshwm sim tiag tiag tseem yuav raug txwv los ntawm tus nqi nkag.
Kev Sib Tw thiab Kev Txhim Kho Kev Txhim Kho
Kev Sib Tw: Kev nce tus ncej tus nqi yuav tsum ntsuas tus nqi thiab kev ua haujlwm. High- zaus tsav tsheb chips thiab siab- kev sib kis ceev (xws li HDMI 2.1, DP 2.0) yuav ua rau cov nqi nce ntxiv.
trends:
Mini / Micro LED thev naus laus zis: Los ntawm kev txo cov pixel loj thiab lub sijhawm hais lus, tus ncej siab dua tuaj yeem txhawb nqa.
AI dynamic zaus hloov: Tsis siv neeg kho tus ncej tus nqi raws li cov ntsiab lus (piv txwv li, txo zaus rau lub zog txuag hauv qhov xwm txheej zoo li qub, nce zaus rau smoothness hauv cov xwm txheej dynamic).
Cov qauv kev sib koom ua ke: Kev lag luam tau txhawb nqa cov ntawv pov thawj ntawm cov nqi sib tw (xws li "conference-grade," "film-grade") los pab cov neeg siv sai sai xaiv cov khoom tsim nyog.
Tus ncej tus nqi ntawm lub rooj sib tham LED yog qhov tshwm sim los ntawm kev sib xyaw ua ke ntawm kev tsav tam sim no, lub sijhawm hais lus, thiab kev tsim qauv. Cov khoom lag luam tseem ceeb npog tus nqi ntawm 60-240Hz, nrog cov qauv high-end ncav cuag ntau dua. Thaum xaiv tus nqi tshiab, xav txog qhov kev siv qhov xwm txheej: 60-120Hz yog qhov tsim nyog rau cov rooj sib tham zoo li qub los tswj cov nqi, thaum 120Hz lossis siab dua yog pom zoo rau kev nthuav qhia dynamic lossis kev sib tham hauv video. Nyob rau hauv lub neej yav tom ntej, nrog kev nce qib hauv kev siv thev naus laus zis, thav duab tus nqi yuav hloov zuj zus ntxiv mus rau "imperceptible latency," muab cov neeg siv nrog kev paub pom ntau dua.
