LED Brightness: Lub teeb ci ntsa iab ntawm lub teeb - em {{. 1000}} {} {{4 {}} CD. Kev siv luminous ntawm ib qho sab hauv tsev LED feem ntau 500 μd {} mcd {} - 1000 mcd, lossis txawm tias saum 1000 MCD.
LED pixel modules: LEDs yog teeb tsa hauv matrices lossis ntu thiab prefabricated rau hauv tus qauv - loj modules. Hom sab hauv tsev cov qauv suav suav nrog 8x8 pixel modules thiab 7-segment digital modules. Cov zaub sab nraum zoov Pixel muaj nyob hauv 4x4, 8 x 8, thiab 8 x 16 pixel specifications. Vim tias txhua pixel nyob rau hauv ib qho chaw sab nraum zoov muaj ob lossis ntau dua LED bundles, lawv kuj tau raug hu ua cov qauv sib txuas.
Pixels thiab pixel inch: txhua tus zuj zus tswj tau coj lub teeb {{}} emnitting yog hu ua pixel (los yog pixel cell). Pixel Inch (∮) hais txog txoj kab uas hla ntawm txhua pixel, ntsuas hauv millimeters.
Rau cov ntaub ntawv sab hauv tsev, ib tus coj ib txwm siv, thiab nws yog ncig pom. Cov khoom sib dhos ua ke rau sab hauv tsev xws li O3.0, ∮3.75, ∮5.0, thiab ∮5.0 yog qhov feem ntau.
Nyob rau hauv ib puag ncig ib puag ncig, txhawm rau txhim kho kev ci thiab ua kom pom kev deb, ib pixel muaj ob lossis ntau dua pawg coj. Txij li thaum pawg LEDs feem ntau tsis yog ncig, lub pixel hla rau sab nraum zoov ntawm khub
Dot suab, pixel ntom, thiab cov ntaub ntawv muaj peev xwm: qhov chaw tshaj tawm: qhov chaw {}} chaw deb lossis teev suab ntawm ob lub pixels ntawm ib qho zaub LED; Tus naj npawb ntawm cov pixels ib chav nyob yog hu ua pixel ntom; Tus nqi ntawm cov ntsiab lus tso tawm ib chav nyob yog hu ua cov ntaub ntawv muaj peev xwm. Peb nqe lus no yeej tseem ceeb piav qhia txog tib lub tswvyim: Pixel suab xav txog qhov kev ncua deb ntawm ib qho ntawm ob lub pixels; Pixel suab thiab pixel ntom yog cov khoom siv lub cev ntawm cov khoom siv zaub. Cov ntaub ntawv muaj peev xwm yog cov khoom siv ntawm cov ntaub ntawv nqa cov peev xwm ntawm pixel ntom.
Tus me dua lub pixel me me, qhov siab dua lub pixel pixel, qhov ntau dua cov ntaub ntawv muaj peev xwm, thiab qhov ze rau qhov kev pom nyob ze.
Qhov loj dua lub pixel, qhov qis dua lub pixel ntom, qhov tsawg dua cov ntaub ntawv muaj peev xwm, thiab qhov deb dua qhov kev pom deb.
Kev daws teeb meem: tus naj npawb ntawm cov kab thiab kab ntawm pixels ntawm qhov screen LED zaub yog hu ua kev daws teeb meem. Kev daws teeb meem yog tag nrho cov pixels ntawm qhov screen, uas txiav txim cov ntaub ntawv muaj peev xwm ntawm cov khoom siv zaub.
LED Zaub Screen qauv: Daim LED Zaub Screen tau tsim los ntawm kev xav tau cov khoom siv pixel, nrog rau cov khoom siv tau raws li qhov xav tau tiag tiag, nrog rau cov khoom siv hluav taws xob ua raws li kev xav tau, cov khoom siv hluav taws xob tau raws li cov khoom siv sib dhos, nrog rau cov khoom siv hluav taws xob ua raws li cov khoom siv
Grayscale: Grayscale yog hais txog qib ntawm ci hloov ntawm kev sib txawv ntawm ib pixel. Ib lub xim tseem ceeb feem ntau muaj 8 txog 12 gayscale ntau. Piv txwv li, yog tias txhua tus xim sib tw muaj 256 grey qib, ib qho dual {}} k xim, thiab tseem hu ua 256-xim zaub.
