Dab tsi koj tus duab TV ua los ntawm
Thaum koj zaum thiab saib xyuas koj txoj kev pab cuam lossis yeeb yaj kiab hauv koj lub TV lossis video projector, koj pom tias muaj dab tsi tshwm sim zoo li cov duab, xws li duab los yog duab. Txawm li cas los xij, kev tshwm sim yog kev dag ntxias. Yog hais tias koj tau txais koj ob lub qhov muag nyob ze ntawm lub TV lossis qhov project screen, koj yuav pom tias nws yog ua los ntawm cov min dots uas yog hlua hauv kab rov tav thiab ntsug kab nyob thiab nce thiab nqes qhov screen.
Lub tswv yim zoo yog qhov zoo tshaj plaws. Thaum peb nyeem nws, nws zoo li peb pom tib cov duab thiab cov tsiaj ntawv, tab sis yog tias koj saib zoo, los yog tau txais ib lub khob loj loj koj yuav pom tias cov tsiaj ntawv thiab cov duab tau los ntawm cov pob zeb me me.
Pixel txhais
Cov dots ntawm TV, video projection screen, PC saib, laptop, los yog txawm ntsiav tshuaj thiab smartphone ntxaij, raug xa mus rau Pixels .
Lub pixel txhais tias yog cov duab duab. Txhua lub pixel muaj cov ntaub ntawv xim liab, ntsuab, thiab xiav (xa mus rau subpixels). Tus nab npawb ntawm pixels uas tau muab dai rau ntawm ib qho screen txiav txim qhov daws teeb meem ntawm cov duab tso tawm.
Yuav kom tso saib cov kev daws teebmeem, ib lub sijhawm pixels pauv tshaj plaws yuav tsum khiav ntawm lub voj voog kom sib txuas thiab nce thiab nqis ntawm qhov screen vertically, teem rau hauv kab thiab kab.
Los txiav txim siab tag nrho cov pixels uas npog tag nrho cov npo ntawm qhov chaw, koj muab cov duab ntawm kab rov tav pixels nyob rau hauv ib kab nrog tus naj npawb ntawm feem ntsug pixels hauv ib kem. Qhov no tag nrho yog hu ua Pixel Census .
Piv txwv ntawm kev daws teeb meem / Pixel Density Relationship
Ntawm no yog qee cov qauv ntawm Pixel Cag rau feem pom tshwm sim hauv cov TV niaj hnub (LCD, Plasma, OLED) thiab video projectors (LCD, DLP):
- 480i / p nruab nrab yog 740 kab rov tav x 480 ntsug pixels = 345,600 pixels tag nrho.
- 720p nruab nrab yog 1,280 kab rov tav x 720 ntsug pixels = 921,600 pixels tag nrho.
- 768p nruab nrab yog 1,366 kab rov tav thiab 768 ntsug pixels = 1,049,088 tag nrho pixels.
- 1080i / 1080p nruab nrab yog 1,920 kab rov tav x 1080 ntsug pixels = 2,073,600 pixels tag nrho.
- 4K (Consumer Standard) nruab nrab yog 3,840 kab rov tav x 2,160 ntsug pixels = 8,294,400 pixels tag nrho.
- 4K (Cinema Standard) sawv cev rau 4,096 kab rov tav x 2,160 vertical pixels = 8,847,360 pixels tag nrho.
- 8K nruab nrab yog 7,680 kab rov tav x 4,320 ntsug pixels = 33,177,600 pixels tag nrho
Pixel Ceev thiab Npo Loj
Ntxiv rau pixel ntom (kev daws teeb meem), muaj lwm yam yuav tsum tau saib xyuas: qhov luaj li cas ntawm qhov screen uas yog tso rau hauv pixels.
Qhov loj tshaj plaws los taw tes yog tias txawm tsis muaj qhov loj npaum li cas me me, tus kab rov tav / ntsug pixel suav thiab pixel ceev tsis hloov rau ib qho kev daws teeb meem. Ua lwm yam lus, yog tias koj muaj 1080p TV, muaj ib txwm puav 1,920 pixels khiav ntawm lub vijtsam horizontally, ua ke, thiab 1,080 pixels khiav nce thiab nce qhov screen vertically, ib kem. Qhov no tau tshwm sim nyob rau hauv pixel ceev txog li ntawm 2.1 lab.
Hauv ua ke, 32-inch TV uas qhia 1080p daws teeb meem muaj tib pixels li 55-nti 1080p TV. Qhov qub tshaj plaws rau cov video projectors. Tus 1080p video projector yuav tso tawm tib lub xov tooj ntawm pixels rau ntawm 80 los sis 200-nti npo.
Pixels Ntauv
Txawm li cas los xij, txawm tias cov pixels nyob qis qis rau ib qho kev pixel ciam hla tas nrho cov npo, qhov hloov yog pes tsawg tus pixels-ib-nti . Ua lwm yam lus, raws li cov npo me me loj dua, tus kheej pom muaj pixels yuav tsum tau loj dua kom ua tiav qhov kev ntsuam xyuas nrog cov xov tooj ntawm cov pixels rau ib qho kev daws teeb meem. Koj tuaj yeem suav seb muaj pes tsawg tus pixels ib nti rau kev txheeb xyuas kev sib tw / kev sib tw.
Pixels Thoob Plaws - TVs vs Video Projectors
Nws tseem ceeb heev uas yuav tsum nco ntsoov tias nrog cov video projectors, cov pixels tau tshwm tawm ib nti rau ib lub projector tshwj xeeb yuav txawv nyob ntawm qhov loj qhov me me siv. Hauv lwm cov lus, tsis zoo li TVs uas muaj qhov ntau thiab tsawg ntawm qhov screen (hauv txhais tau tias, 50-inch TV yeej yog ib lub TV 50-inch), video projectors yuav tso saib cov duab hauv ntau qhov ntau thiab tsawg, nyob ntawm tus projector lens design thiab qhov kev ncua ntawm lub projector yog muab tso rau ntawm ib qho screen los yog phab ntsa.
Tsis tas li ntawd, nrog 4K projectors, muaj ntau txoj kev zoo li cas cov duab tshwm nyob rau ntawm ib qho screen uas tseem cuam tshuam npo loj, pixel ceev, thiab pixels ib nti kev sib raug zoo.
Lub Kab Hauv Qab
Txawm hais tias Pixels yog lub hauv paus ntawm yuav ua li cas TV duab muab tso ua ke, nws muaj lwm yam uas yuav tsum tau saib TV zoo los yog cov duab video, xws li xim, qhov sib txawv, thiab ci ntsa iab. Vim tias koj muaj ntau pixels, tsis txhais tau tias koj yuav pom qhov zoo tshaj plaws ua tau duab hauv koj lub TV lossis video projector.
