Grayscale theem hauv LED cov lus hais txog tus naj npawb ntawm qhov ci ntawm qhov tsaus ntuj mus rau qhov ci tshaj plaws uas cov zaub tuaj yeem pom. Grayscale qib yog qhov taw qhia tseem ceeb rau kev ntsuas cov xim nthuav dav ntawm LED zaub, txiav txim siab qhov kev hloov pauv ntawm qhov ci ntsa iab ntawm lub vijtsam tuaj yeem pom thaum pom cov duab.
Cov qib Greyscale feem ntau sib txawv raws li cov hauv qab no:
Binary Bits: Grayscale qib yog txhais los ntawm tus lej ntawm binary khoom. Feem ntau greyscale qib yog 8-ntsis, 10-ntsis, 12-ntsis, thiab ntau dua. Txhua qhov me ntsis ntxiv ob npaug ntawm cov kev sib txawv ntawm qhov ci ntsa iab uas tuaj yeem pom. Piv txwv li, qib 8-ntsis greyscale tuaj yeem tso saib 256 (2^8) qhov sib txawv ntawm qhov ci ntsa iab, thaum 10-ntsis greyscale qib tuaj yeem tso saib 1024 (2^10) qhov sib txawv ntawm qhov ci.
Brightness Variations: Qhov siab dua ntawm qib grey, qhov ci ntsa iab ntau qhov kev hloov pauv tuaj yeem pom, ua rau cov xim hloov tau zoo dua thiab muag heev. Qhov no yog qhov sib piv rau tus neeg pleev kob lub palette; cov xim ntau dua, cov nplua nuj thiab ntau ntxiv cov duab kos.
Kev Pom Kev Pom Zoo: High grayscale qib LED cov lus qhia muaj txiaj ntsig zoo hauv kev ua haujlwm xim thiab nthuav dav. Cov xim hloov pauv tau zoo dua qub thiab du, thiab cov ntsiab lus zoo dua. Txawm hais tias nws yog ib qho screen LED sab hauv tsev hauv chav sib tham lossis sab nraum zoov LED daim duab kos, lub siab greyscale LED zaub tuaj yeem nthuav tawm cov duab pom tseeb dua thiab muag heev.
Nov yog qee qhov kev xav paub txog qhov sib txawv ntawm qib greyscale:
8-ntsis greyscale: Thaum nws tuaj yeem tso saib qee theem ntawm qhov ci, qhov kev hloov pauv tuaj yeem tshwm sim me ntsis, thiab xim kev ua tau zoo kuj txwv.
Cov qib grayscale siab dua (piv txwv li, 10-ntsis, 12-ntsis): Cov no tuaj yeem ua kom pom kev hloov pauv ntawm qhov ci ntsa iab ntau dua, kev hloov xim ntau dua, thiab cov duab tiag tiag.
(Ceeb Toom: Cov duab saum toj no yog cov duab qhia txog qib grey, uas qhia qhov ci ntsa iab ntawm LED zaub ntawm qib greyscale sib txawv.)
Hauv cov ntsiab lus, qib greyscale yog qhov taw qhia tseem ceeb rau kev ntsuas cov xim nthuav dav thiab cov duab zoo ntawm LED zaub. Los ntawm kev nce qib grayscale, xim kev ua tau zoo thiab nthuav dav rendering peev xwm ntawm LED zaub tuaj yeem txhim kho tau zoo, coj cov neeg siv kev paub txog qhov tseeb thiab muag pom. Nrog kev nce qib thev naus laus zis txuas ntxiv thiab nce kev lag luam xav tau, qib greyscale ntawm LED cov lus yuav txuas ntxiv txhim kho yav tom ntej, coj kev yooj yim dua thiab kev lom zem rau peb lub neej.
