Lub sij hawm daws teeb meem piav qhia txog cov dots, lossis pixels, uas cov duab muaj lossis tuaj yeem tso tawm ntawm lub computer saib, TV, lossis lwm yam khoom siv. Cov dots no muaj nyob rau hauv ntau txhiab lossis ntau lab, thiab ntau dua lawv tus lej, qhov ntau dua qhov pom tseeb thiab zoo.
Kev daws teeb meem hauv Computer Monitors
Lub khoos phis tawj saib qhov kev daws teeb meem yog hais txog kwv yees tus lej pixels uas lub cuab yeej muaj peev xwm nthuav tawm. Nws yog qhia raws li tus naj npawb ntawm kab rov tav dots los ntawm tus naj npawb ntawm ntsug dots; Piv txwv li, 800 x 600 daws teeb meem txhais tau tias lub cuab yeej tuaj yeem pom 800 pixels hla los ntawm 600 pixels nqes. Nyob rau hauv tag nrho, qhov screen no qhia 480,000 pixels.
Cov kev daws teeb meem hauv computer ib txwm suav nrog:
- 1366x768
- 1600 x 900
- 1920 x 1080
- 2560 x 1440
- 3840 x 2160 (feem ntau hu ua 4k daws teeb meem)
kab hauv qab
Rau TV, kev daws teeb meem zoo ib yam tab sis qhia txawv me ntsis. TV duab zoo tsom ntau dua ntawm pixel ceev dua li nws ua tus lej tag nrho ntawm pixels. Hauv lwm lo lus, tus naj npawb ntawm pixels ib chav tsev ntawm cheeb tsam (feem ntau ib nti) dictates daim duab zoo, tsis yog tag nrho cov pixels. Yog li, TV qhov kev daws teeb meem yog qhia hauv pixels ib nti (PPI lossis P). Cov kev daws teeb meem hauv TV feem ntau yog 720p, 1080p, thiab 2160p, tag nrho cov uas suav tias yog siab txhais.
Kev daws teeb meem hauv cov duab
Qhov kev daws teeb meem ntawm cov duab hluav taws xob (duab, duab, thiab lwm yam) yog hais txog cov pixels uas nws muaj, feem ntau qhia tau ntau lab pixels, lossis megapixels (MP). Cov koob yees duab digital thiab lub koob yees duab smartphone feem ntau yog ntsuas los ntawm tus lej megapixels hauv cov duab uas lawv ntes.
Qhov ntau dua ib daim duab daws teeb meem, nws qhov zoo dua. Raws li nrog lub khoos phis tawj saib, qhov ntsuas tau qhia raws li qhov dav los ntawm qhov siab, muab faib ua tus lej hauv megapixels. Piv txwv li, ib daim duab uas yog 2048 pixels hla los ntawm 1536 pixels down (2048 x 1536) muaj 3, 145, 728 pixels; Hauv lwm lo lus, nws yog 3.1-megapixel (3MP) duab.
Txawm hais tias yog xa mus rau lub khoos phis tawj, TVs, lossis cov duab, kev daws teeb meem yog qhov qhia txog qhov tseeb thiab qhov zoo ntawm cov duab lossis duab.
