1. Txhim kho qhov sib piv ntawm cov xim puv xim LED
Qhov sib txawv yog ib qho tseem ceeb uas cuam tshuam rau qhov pom kev. Feem ntau hais lus, qhov siab dua qhov sib piv, qhov pom tseeb thiab pom tseeb dua cov duab, thiab cov xim ci dua thiab ci dua. High contrast yog pab tau heev rau cov duab clarity, nthuav dav kev ua tau zoo, thiab grey theem kev ua tau zoo.
Thib ob, txhim kho qib grey ntawm cov xim puv xim LED
Cov qib grey ntawm LED zaub screen yog hais txog qhov ci ntsa iab uas tuaj yeem txawv ntawm qhov tsaus ntuj mus rau qhov ci tshaj plaws ntawm ib qho xim thawj xim ci. Qhov siab dua qib grey ntawm cov xim puv xim LED zaub screen, cov xim nplua nuj thiab cov xim ci dua; vice versa, Cov xim zaub yog ib leeg, thiab kev hloov pauv yooj yim. Qhov nce ntawm qib grey tuaj yeem ua rau kom cov xim qhov tob, ua rau cov duab theem ntawm cov duab xim nce geometrically. Niaj hnub no, ntau cov xim LED zaub manufacturers tuaj yeem teeb tsa qhov grey nplai ntawm cov zaub rau 14-16-ntsis, kom cov duab theem sib txawv cov ntsiab lus thiab cov nyhuv ntawm cov zaub yog qhov muag heev, tiag tiag, thiab muaj yeeb yuj.
Thib peb, txo cov dot suab ntawm cov xim puv xim LED
Txo cov dot pitch ntawm cov xim puv xim LED tuaj yeem txhim kho qhov pom tseeb ntawm lub vijtsam, vim tias qhov me me ntawm qhov dot pitch, qhov siab dua pixel ceev ntawm ib chav tsev ntawm cov xim puv xim LED, thiab cov ntsiab lus ntxiv uas tuaj yeem ua tau. ua kom pom. Qhov ntau ilv thiab muaj tiag.
Plaub, kev sib xyaw ua ke ntawm cov xim puv xim LED thiab video processor
LED video processor siv tau cov algorithms siab heev los hloov cov teeb liab nrog cov duab tsis zoo, thiab ua cov txheej txheem xws li de-interlacing, ntug sharpening, thiab cov lus tsa suab los txhim kho cov duab qhia cov ntsiab lus thiab txhim kho cov duab zoo. Lub video processor duab scaling processing algorithm yog siv los xyuas kom meej tias cov duab yees duab yog scaled kom muaj lub sharpness thiab grey theem ntawm cov duab mus rau qhov loj tshaj; Tsis tas li ntawd, tus txheej txheem video kuj tseem yuav tsum muaj kev nplua nuj ntawm cov duab hloov kho thiab hloov cov teebmeem. Brightness, contrast, thiab greyscale raug ua tiav los xyuas kom meej tias cov xim tag nrho LED tso tawm cov duab mos thiab meej.
