Koj tau muab piv pixel suab, ci ntsa iab, thiab tus nqi. Txawm li cas los xij, thaum lub koob yees duab pans hla koj lub vijtsam theem thiab cov kab scan phem dov los ntawm kev tshaj tawm, tsis muaj qhov tseem ceeb. Refresh tus nqi - qhov specification feem ntau buyers skim dhau los - ntsiag to txiav txim siab seb koj LED zaub zoo li flawless nyob rau hauv tib neeg, ntawm lub koob yees duab, thiab nyob rau hauv qeeb- suab replay.
Qhov Refresh Rate Tiag tiag txhais tau li cas
Refresh tus nqi ntsuas pes tsawg zaus hauv ib ob qhov LED zaub redraws tag nrho cov duab, qhia hauv Hertz (Hz). Ib qho screen ntsuas ntawm 1,920 Hz repaint nws tus kheej 1,920 zaug txhua ob. Cov lej siab dua txhais tau tias cov lus tsa suab zoo dua thiab, qhov tseem ceeb rau txhua tus neeg ua yeeb yaj kiab ntawm qhov screen, tsawg dua cov khoom qub.
Kev tsis meej pem feem ntau tshwm sim vim hais tias ob lo lus cuam tshuam tau sib xyaw:
- Ncej tus nqi- pes tsawg video thav duab koj cov ntsiab lus xa tawm ib ob (feem ntau 24–60 fps).
- Refresh tus nqi- pes tsawg zaus cov zaub nws tus kheej redraws, ywj siab ntawm qhov chaw.
Ib qho zaub tsuas tuaj yeem zoo li du raws li nws tus nqi refresh tso cai, txawm tias cov ntsiab lus zoo npaum li cas.
Vim li cas Tsawg Refresh Rate Hurts - Tshwj xeeb ntawm Lub Koob Yees Duab
Thaum lub koob yees duab kaw thiab lub vijtsam rov ua dua lub voj voog poob ntawm kev sib txuas, qhov tshwm sim yog pom banding, scanning kab, lossis flicker. Peb qhov xwm txheej ua rau qhov mob no:
- Tshaj tawm thiab nyob streaming.Cov duab kev hais kwv txhiaj, kev ntaus kis las, thiab TV studios ntes lub vijtsam ncaj qha; qis refresh tus nqi tig ib tug hwm installation mus rau hauv ib qho kev txaj muag.
- Slow- suab replay.Cov chaw ntau pob hauv ib puag ncig cov yeeb yaj kiab ua yeeb yaj kiab ntawm tus ncej siab qhia cov kab txaij uas tsis tau tshwm sim rau qhov muag liab qab.
- Kev yees duab ntawm cov xwm txheej.Cov qhua yees duab koj theem; Yog tias qhov screen flickers hauv txhua daim duab, lub sijhawm yuav cuam tshuam.
Tib neeg lub qhov muag tsis tshua pom qhov teeb meem nyob. Cov koob yees duab ib txwm ua. Qhov asymmetry yog vim li cas tus nqi refresh yuav tsum tau saib ua ntej kev yuav khoom, tsis yog tom qab.
Koj xav tau pes tsawg Hz?
Tsis muaj ib lo lus teb tiag. Daim ntawv thov, kev siv lub koob yees duab, thiab pob nyiaj siv txhua yam ua lub luag haujlwm:
| Daim ntawv thov | Pom zoo Refresh Rate | Vim li cas |
|---|---|---|
| Static advertising, billboards | 960-1,920 Hz | Tsis muaj koob yees duab; smooth playback txaus |
| Sab hauv tuam txhab / muag khoom | 1,920 Hz | Qee zaus ua yeeb yaj kiab, saib yooj yim |
| Theem, concerts, TV studios | 3,840 Hz + | Tshaj tawm cov koob yees duab, qeeb suab, XR pem teb |
| Stadium perimeter & kev ua si | 3,840 Hz + | Siab -frame- tus nqi tshaj tawm |
Raws li txoj cai ntawm tus ntiv tes xoo, txhua yam tsis tu ncua tau txais txiaj ntsig los ntawm 3,840 Hz lossis siab dua. Niaj hnub nimno tsav tsheb ICs ua tiav qhov no yam tsis muaj kev cuam tshuam kev ua haujlwm grey, yog li kev lag luam tawm - tawm uas ib zaug muaj tau ploj mus.
Dab tsi ntxiv cuam tshuam rau - Lub koob yees duab Performance
Refresh tus nqi tsis ua haujlwm ib leeg. Peb qhov kev sib koom ua ke txiav txim siab qhov kawg tshwm sim:
- PWM greyscale processing.Siab dua - cov neeg tsav tsheb me me ua kom cov xim ruaj khov ntawm tus nqi refresh siab, zam kev hloov xim ntawm lub koob yees duab.
- Lub koob yees duab shutter ceev.Txawm tias 3,840 Hz npo tuaj yeem ua haujlwm nyob rau hauv qhov chaw kaw qhov txawv txav; phim lub koob yees duab chaw rau cov zaub.
- Genlock / ncej sync txhawb.Rau XR thiab virtual ntau lawm, xauv lub vijtsam tshiab rau lub koob yees duab tshem tawm cov khoom cuav tag nrho.
Ib daim ntawv teev cov neeg yuav khoom ceev
Ua ntej kos npe rau daim ntawv cog lus, paub meej tias:
Lub refresh tus nqi specification hauv kev sau ntawv - "siab refresh" tsis muaj tus lej txhais tau tias me me.
Txawm hais tias tsav tsheb IC txhawb 3,840 Hz ntawm koj lub hom phiaj ci.
Kev sim lub koob yees duab nyob, lossis cov duab thaij duab nrog koj cov khoom siv tshaj tawm.
Grayscale kev ua tau zoo ntawm qhov ci qis, qhov twg pheej yig tsav tsheb degrade ceev tshaj plaws.
Xaus
Refresh tus nqi yog pom tsis tau txog thaum nws ua tsis tiav ntawm cov neeg tuaj saib - lossis lub koob yees duab. Qhia meej tias nws raug nqi me ntsis ntawm lub sijhawm yuav khoom thiab tiv thaiv qhov pom tshaj plaws, feem ntau sib koom ua haujlwm tsis ua haujlwm hom LED zaub tuaj yeem muaj. Raws li kev tshaj tawm xov xwm tshaj tawm mus rau hauv kev hais kwv txhiaj, kev ua kis las, thiab khw muag khoom, kev hloov siab tshiab tau hloov pauv ntawm qhov kev xaiv hwm mus rau qhov kev cia siab hauv paus.
