Icho chifananidzo cheTV yako yakagadzirwa
Paunogara pasi uye uchiona purogiramu yako yaunoda kana mafirimu paTV kana muvhidhiyo yeprojekti, unoona zvinoratidzika sezvikamu zvezvifananidzo zvakakwana, semufananidzo kana firimu. Zvisinei, kuonekwa kuri kunyengedza. Kana iwe ukatarira meso ako pedyo neTV kana kuti kuratidzira, unoona kuti yakaumbwa nematombo maduku akabatanidzwa mumitsetse yakananga uye yakasvikirira kumusoro uye kumusoro uye pasi pasi pehwindo.
Kufananidza kwakanaka pepanhau rakawanda. Patinenge taiverenga, zvinoratidzika sekuti tiri kuona mifananidzo isina kufanana uye netsamba, asi kana ukatarisa zvakanyanya, kana kuwana girasi rinosimudza iwe uchaona kuti iyo tsamba uye mifananidzo yakaumbwa madotsani maduku.
Iyo Pixel Inotsanangurwa
Mavara ari paTV, mavhidhiyo ekuongorora screen, PC monitor, laptop, kana kunyange tablet uye smartphone skrini, dzinonzi Pixels .
A pixel inotsanangurwa sechinhu chechifananidzo. Pixel imwe neimwe ine ruvara rwebhuruu, ruvara, uye ruvara rwebhuruu (dzinonzi subpixels). Nhamba yepikisiki iyo inogona kuratidzwa pahwindo inogadzirisa kusarudzwa kwemifananidzo yakaratidzwa.
Kuti uratidze chisarudzo chechinyorwa chakatarwa, nhamba yakatarwa yepiksekisi inofanira kuenderera mberi nechiyero chepamusoro uye zvichikwira uye pasi pasi pechirati chirimo, yakarongedzwa mumitsara nemirasi.
Kuti uone nhamba yakazara yepikisikisi yakavhara yose skrini, unowedzera nhamba yemapiksesi ekumhanya mune imwe mutsara pamwe nenhamba yemapiksesi akafanana mune imwe korombo. Iyi yose inonzi inonzi Pixel Density .
Mienzaniso yeSarudzo / Pixel Density Wehukama
Heano mimwe mimwe mienzaniso yePixel Density rezvigadziriswa zvinowanzoonekwa muTV mazuva ano (LCD, Plasma, OLED) uye vhidhiyo projector (LCD, DLP):
- 480i / p inomirira 740 inopenya x 480 mazamu pixels = 345 600 mazana pixels.
- 720p inomiririra 1,280 inopenya x 720 vertical pixels = 921 600 mazana pixels.
- 768p inomiririra 1,366 dzakatenderera uye 768 mapikisi emawindo = 1,049 088 mapikisi ose.
- 1080i / 1080p inomiririra 1,920 inopenya x 1080 vertical pixels = 2,073 600 mazana pixels.
- 4K (Consumer Standard) inomiririra 3,840 yakapetwa x 2,160 pixels yakadzama = 8 294 400 mazana pixels.
- 4K (Cinema Standard) inomiririra 4,096 inopenya x 2,160 pixels vertical = 8 847 340 pixels yakazara.
- 8K inomiririra 7 680 horizontal x 4,320 pixels vertical = 33 177 600 mazana pixels
Pixel Density uye Screen Size
Mukuwedzera kune pixel density (resolution), pane chimwe chinhu chinofanira kutarisisa: ukuru hwekona iri kuratidza mapikiseli.
Chinhu chikuru chekutaura ndechokuti pasinei nepo chaiyo yechisikiti chekuyera, iyo yakananga / yakajeka pixel count uye pixel mashizha haashanduki pane imwe sarudzo. Mune mamwe mazwi, kana iwe une TV ye1080p, pane nguva dzose 1 920 pixels inomhanya kune imwe skrini pane imwe nzvimbo, pamutsara, uye 1,080 pixels ichikwira uye ichidzika pasi pehwindo, zvichienderana nechikamu. Izvi zvinoguma nehukisi hwepiksikisi hweanenge mamiriyoni 2.1.
Mune mamwe mazwi, TV 32-inch inoratidza 1080p chisarudzo ine nhamba yakafanana yepikisiki se 55-inch 1080p TV. Chinhu chimwechetecho chinoshanda kuvhidhiyo projekiti. A 1080p video projector icharatidza nhamba imwechete yepiksekisi pane imwe svondo 80 kana 200 inch.
Pixels Per Inch
Zvisinei, kunyange zvazvo nhamba yemapiksesi inogara ichienderera kune imwe nhamba yepikeleri yakawanda pahukuru hwese- skrini, chii chinoshandiswa iyo nhamba yemapiksesi-per-inch . Mune mamwe mazwi, sezvo svondo rekuvharidzirwa rinowedzera, mapikisi emaoneswa ega ega anofanirwawo kuva makuru kuti azadze chinyorwa pamwe nenhamba yakakodzera yepiksesi yekusarudza kumwe. Iwe unogona chaizvo kuverenga nhamba yemapikseli pamasendimita yehutano chaihwo / ukama hwehutachiona hwemahwindo.
Pixels Per Inch - TVs vs Video Projectors
Zvakakoshawo kuziva kuti nemavhidhiyo mapurojekiti, mapikisi ekuratidzwa nemasendiki emujekisi chaiwo anogona kusiyanisa zvichienderana nehukuru hwesikrini rinoshandiswa. Mune mamwe mazwi, kusiyana nemavhidhiyo ane michina yakanyanyisa mashizha (mune mamwe mazwi, se-50-inch TV nguva dzose iri 50-inch TV), vhidhiyo vhidhiyo inogona kuratidza mifananidzo mumhando dzakasiyana-siyana dzekrini, zvichienderana nekwenyoro yejeri yeprojekti uye nzvimbo iyo purojekiti inoiswa kubva pachikona kana rusvingo.
Mukuwedzera, nevanoridzidzira 4K, kune nzira dzakasiyana-siyana pamusoro pekuti mifananidzo inoratidzwa sei pachigadziko iyo inobatawo mashizha e-screen, pixel density, uye pixels nehukama hwepasita.
The Bottom Line
Kunyange zvazvo Pixels ari nheyo yekuti firimu yeTV inosanganiswa sei, kune zvimwe zvinhu zvinodiwa kuti uone kunaka kweTV kana kuti mavhidhiyo emagetsi, zvakadai soruvara, kusiyana, uye kupenya. Kungofanana nokuti une mapikisi emazhinji, hazvirevi kuti iwe uchaona mufananidzo wakanakisisa paTV kana kuti video projector.
