Dab tsi yog qhov dynamic scanning ntawm sab hauv tsev high-txhais coj zaub?
Nrog txoj kev loj hlob ntawm LED thev naus laus zis, qhov ci ntsa iab ntawm sab hauv tsev high-txhais LED cov lus tseem nce ntxiv, thiab qhov loj me tau txais me me thiab me me, uas qhia tau tias ntau cov lus qhia hauv tsev high-txhais LED yuav dhau los ua cov qauv dav dav.Txawm li cas los xij, vim yog kev txhim kho ntawm LED ci ntsa iab thiab pixel ceev, cov kev xav tau tshiab thiab siab dua tau coj mus rau kev tswj thiab tsav tsheb ntawm LED cov ntxaij vab tshaus.Raws li qhov kev tshuaj ntsuam sab hauv tsev muaj kev txhawj xeeb, txoj kev tswj hwm tam sim no siv cov kab-kem sub-control hom, uas feem ntau hu ua hom scanning.Tam sim no, cov qauv tsav tsheb ntawm sab hauv tsev high-txhais coj cov ntxaij vab tshaus muaj xws li static scanning thiab dynamic scanning.Muab faib ua static tiag pixels thiab static virtual, dynamic scanning kuj muab faib ua dynamic tiag tiag duab thiab dynamic virtual;

Nyob rau sab hauv tsev high-txhais coj zaub, qhov piv ntawm cov xov tooj ntawm cov kab teeb nyob rau tib lub sijhawm rau cov kab hauv tag nrho cheeb tsam yog hu ua scanning hom.Lub scan tseem muab faib ua 1/2 scan, 1/4 scan, 1/8 scan, 1/16 scan thiab lwm yam kev tsav tsheb.Uas yog hais tias, tsav hom ntawm lub vijtsam zaub yog txawv, yog li cov chaw ntawm daim npav txais kuj txawv.Yog tias daim npav tau txais yog thawj zaug siv rau ntawm 1/4 scan screen thiab tam sim no siv rau ntawm lub vijtsam zoo li qub, tom qab ntawd cov zaub ntawm cov zaub yuav taws txhua 4 kab.Feem ntau, daim npav txais tuaj yeem teeb tsa.Tom qab txuas daim npav xa, tso saib, lub computer thiab lwm yam tseem ceeb, koj tuaj yeem nkag mus rau cov software cuam tshuam ntawm lub khoos phis tawj los teeb tsa.Yog li ntawm no peb yuav xub qhia txog hom scanning thiab lub hauv paus ntsiab lus ntawm sab hauv high-txhais coj zaub.

1. Scanning txoj kev ntawm sab hauv tsev high-txhais coj zaub:

1. Dynamic scanning: Dynamic scanning siv "point-to-kem" tswj los ntawm cov zis ntawm tus tsav tsheb IC mus rau cov ntsiab lus pixel.Dynamic scanning yuav tsum muaj kev tswj xyuas hluav taws xob, thiab tus nqi qis dua li qhov kev soj ntsuam zoo li qub, tab sis cov duab pom tsis zoo thiab qhov ci tsis zoo yog qhov loj..

2. Static scanning: Static scanning yog siv "point-to-point" tswj los ntawm cov zis ntawm tus tsav tsheb IC mus rau pixels.Kev soj ntsuam zoo li qub tsis tas yuav muaj kev tswj xyuas circuits, thiab tus nqi siab dua dynamic scanning, tab sis cov nyhuv ntawm cov zaub yog zoo, stability yog zoo, thiab brightness ploj.Qhov zoo ntawm kev ua me me, thiab lwm yam.

Qhov thib ob, lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm sab hauv tsev siab-txhais coj zaub 1/4 scan hom:

Nws yog lub sij hawm rau txhua kab ntawm lub hwj chim mov V1-V4 tig rau 1/4 ntawm lub sij hawm raws li cov kev cai tswj nyob rau hauv ib tug ncej ntawm daim duab.Qhov kom zoo dua ntawm qhov no yog tias cov yam ntxwv ntawm LEDs tuaj yeem siv tau zoo dua thiab cov nqi kho vajtse tuaj yeem txo qis.Qhov tsis zoo yog tias hauv 1 thav duab ntawm cov duab, txhua kab ntawm LEDs tsuas tuaj yeem tso saib 1/4 ntawm lub sijhawm.

Thib peb, raws li sab hauv tsev high-txhais coj zaub hom scanning txoj kev faib:

1. Cov txheej txheem scanning ntawm sab hauv tsev high-definition coj cov khoom siv hluav taws xob: P4, P5 yog qhov tam sim no 1/16, P6, P7.62 yog qhov tam sim no 1/8.

2. Scanning hom ntawm sab nraum zoov thiab sab hauv tsev high-txhais coj cov khoom siv hluav taws xob: P10, P12 yog qhov tam sim no 1/2, 1/4, P16, P20, P25 yog qhov zoo li qub.

3. Cov txheej txheem scanning ntawm ib leeg thiab ob chav xim sab hauv tsev high-txhais LED zaub feem ntau yog qhov tam sim no 1/4, tsis tu ncua tam sim no 1/8 scan, thiab tsis tu ncua tam sim no 1/16 scan.
