Ungakhetha kanjani isikrini seprojektha?

I-projektha iyithuluzi eliwusizo hhayi kuphela phakathi nezingqungquthela, kodwa nasekhaya. Idala kabusha isithombe esivezwa kukhompuyutha ephathekayo, ideskithophu noma idivayisi yeselula. Kulesi sihloko, sizokukhombisa ukuthi ungakhetha kanjani isikrini se-projektha nokuthi yimiphi imingcele yesikrini okufanele uyinake.

Izicelo Eziwusizo Ze-Screen Projector

Isikrini sokuqagela esiphathekayo siwusizo ezimweni eziningi, kokubili empilweni yobungcweti kanye neyansuku zonke. Cishe uke wahlangana naye emsebenzini, esikoleni, nasekolishi. Ehhovisi, imishini edingekayo yokubonisa izethulo ngamagrafu kanye ne-infographics. Ayikho enye indlela bonke abasebenzi abangabona ngayo isithombe esicacile. Ekhaya, isikrini sokuqagela silungele ukubuka amafilimu nomndeni noma nabangane. Isikrini sekhwalithi sizothuthukisa ukubuka kwasekhaya ngisho nakumshini wokudlala oshibhile, ongathuthuki kakhulu.

Kungani uthenge isikrini sokudlala?

Ungabuka amamuvi kusuka ku-smartphone yakho, ithebhulethi, isidlali seDVD, ngisho nakwi-flash drive, idrayivu yangaphandle, noma ikhonsoli. Izophinde inikeze ikhwalithi yesithombe engcono kakhulu kunomfanekiso odongeni, ikakhulukazi uma ingemhlophe. Kunezinhlobo ezahlukene zezikrini - nansi inkomba esheshayo yabaqalayo.

Kunezinhlobo ezimbili zezikrini zokuqagela ezitholakalayo emakethe.

Ngokuyisisekelo sihlukanisa izikrini ngokuthi ziyaphatheka noma "zimile". Izinhlobo ezimbili zingahlukaniswa:

• I-MOBILE - kunalokho zinconywa kubantu abadinga isikrini sezethulo ze-multimedia, isibonelo, ngezinjongo zobuchwepheshe. Isikrini esinjalo sithuthwa ngepotimende elihlangene, eliphinde libe luhlaka. Ibekwe phansi ngqo. Olunye uhlobo isikrini se-stand-up projector esifakwe i-tripod - kufanelekile ukuba ne-tripod elungiseka ukuphakama.
• Ifakwe unomphela - ayingxenye yemishini yamakamelo enkomfa, kodwa angasetshenziswa nasekhaya. Zifakwe odongeni noma ophahleni. Uma unophahla olungamanga ekhaya lakho, khetha isikrini seprojektha sikasilingi kagesi esifakwe izinto ezilungiselwe ukufakwa kulolo hlobo losilingi.

Izinhlobo zesikrini ngenxa yezinye izici

Ngokohlobo lokuvula (ukukhishwa) kwesikrini, kukhona:

• izikrini eziqhutshwa ngesandla - usebenzisa i-elementi ehloselwe lokhu. Ungayinweba ngokwenza. Lolu hlobo lwesikrini ngeke lusebenze emakamelweni aphezulu uma ufuna ukusikhweza ophahleni.
• izikrini zikagesi (zandisa ngokuzenzakalelayo) - zinganwetshwa futhi zifakwe ukude, kusetshenziswa isilawuli kude esinamathiselwe esikrinini, noma kusetshenziswa inkinobho okufanele yakhelwe odongeni. Isikrini sokubonisa esizenzakalelayo sizosebenza kangcono ekhaya nasemagunjini aphezulu.

Hlukanisa ngohlobo lomngcele

• izikrini zohlaka - ifakwe ifreyimu yokuzinzisa, ngokuvamile emnyama noma insimbi. Zifanele kokubili ukulengiswa nokukhwezwa ku-tripod. Uhlaka lunomsebenzi wokuhlobisa, ngakho-ke kuyisinqumo esihle semidlalo yaseshashalazini yasekhaya.
• izikrini ezinalokho okubizwa ngokuthi ama-tensioners - kulo lonke ubude bohlangothi kufakwe imigqa eqinisa impahla ukuze ibushelelezi futhi ilingane, ngaphandle kokugoqa nokugoqa.

Imiphi imingcele yesikrini okufanele ngiyinake?

Nawa amapharamitha abaluleke kakhulu okufanele uwajwayeze lapho uthenga:

• Ukucatshangelwa kokuqala okubaluleke kakhulu lapho ukhetha isikrini sokuqagela ukuthi ifomethi yehlathiisikrini esisisekelayo sasifana neprojektha okungeyakho (noma ohlela ukuyithenga).
• Ukukhanya okukhanyayo (okwaziwa ngokuthi inzuzo) - uma igumbi likhanya, inani lokubonisa kufanele libe phezulu. Izitezi ezimnyama nezindonga ezimnyama azivamile ukutholakala ezindlini nasezindlini, ngakho-ke i-coefficient ebangeni ukusuka ku-1.0 kuya ku-1.3 izoba yindawo yonke. Inzuzo yayo eyengeziwe ukuthi inikeza i-engeli yokubuka ebanzi. Ngeshwa, kunobudlelwano phakathi kobude besici nobubanzi be-engeli - into enkulu, i-engeli encane.
• isinqumo - Ukuphakama kwesikrini, kuba ngcono ikhwalithi yesithombe nemininingwane. Ngaphezu kwalokho, uma uthenga isikrini sokucaca okuphezulu, ungaqiniseka ukuthi sizohlala isikhathi eside. Inqubekelaphambili esheshayo yezobuchwepheshe isho ukuthi kuyadalwa amadivaysi eselula esimanjemanje. Izikrini ezinokulungiswa okuphansi ngeke zisahambisana nazo. Okwamanje ukulungiswa okungcono kakhulu ngu-1280x800, 1024x768, 1920x1080 (Full HD).

Amanye amaphuzu okufanele uwakhumbule

• Indlela yokukhweza - odongeni noma ophahleni - izikrini zifakwe amabakaki akuvumela ukuba uzibeke odongeni noma ophahleni. Izibambo ezifanele kufanele zinikezwe umenzi - qaphela lokhu lapho ukhetha. Isikrini seprojektha yosilingi kufanele sibe nekhasethi eliklanywe kahle elizolivumela ukuthi libekwe ngaphezu kosilingi, noma kunalokho, esikhaleni esiphakathi kophahla nophahla.
• umngcele wesikrini - inkinga ebonakala ingabalulekile enomsebenzi wokuhlobisa kuphela. Nokho, lokhu kungase kuthinte kakhulu ikhwalithi yesithombe esibonisiwe! Umngcele omnyama uzosiza ukuthuthukisa umehluko wesithombe osibona kuprojektha. Lokhu kuphinde kuthinte ukugxila esithombeni - akuphazamisi.
• Umbala wesikrini - uzothola izikrini ezimhlophe nezimpunga emakethe. Lezi zamuva zitholakala ngemibala empunga enamazinga ahlukahlukene okugcwala. Kodwa-ke, zinconywa emakamelweni amnyama. Uma ufuna isikrini sokubuka amamuvi ekhaya, khetha okumhlophe. Ngokufanayo, esimweni sezikrini zezethulo ze-multimedia emsebenzini, amakamelo amaningi ahluke kakhulu ngokwemibandela evela ku-cinema.

Isikrini seprojektha esimweni setiyetha yasekhaya kufanele silengiswe endaweni ephakeme okungenani imitha elilodwa ngaphezu kwephansi. Khumbula ukuqala ukukhetha isikrini kuphela uma usukhethile noma usuvele uthenge iprojektha, hhayi okuphambene nalokho! Intengo yesikrini kufanele ifinyelele ku-30% yenani leprojektha.

Amathiphu amaningi angatholakala esigabeni se-Electronics.
