N’chifukwa chiyani tifunika kugwiritsa ntchito chophimba cha LED m’malo mwa chowonetsera chachikhalidwe? Kodi pali zovuta zina za ukadaulo wowonetsera?

Masiku ano, malo ambiri owonetsera mafilimu akugwiritsabe ntchito ukadaulo wowonetsera. Izi zikutanthauza kuti chithunzicho chimawonetsedwa pa nsalu yoyera ndi pulojekitala. Pamene chophimba chaching'ono cha LED chimayamba, chimayamba kugwiritsidwa ntchito m'minda yamkati, ndipo pang'onopang'ono chimalowa m'malo mwa ukadaulo wowonetsera. Chifukwa chake, malo omwe angakhalepo pamsika wa zowonetsera zazing'ono za LED ndi akulu kwambiri.
Ngakhale kuwala kwakukulu ndi chimodzi mwa zinthu zabwino kwambiri pa sikirini ya LED, nthawi zambiri imagwiritsa ntchito mfundo yodziwunikira yokha, pixel iliyonse imatulutsa kuwala padera, kotero zotsatira zake zimakhala zofanana m'malo osiyanasiyana a sikirini. Kuphatikiza apo, sikirini ya LED imagwiritsa ntchito maziko onse a sikirini yakuda, yomwe ili ndi kusiyana kwakukulu kuposa ukadaulo wachikhalidwe wowonetsera.

Kawirikawiri, zida zambiri zosewerera zomwe zimagwiritsidwa ntchito m'mabwalo achikhalidwe ndi ukadaulo wowonetsera. Chifukwa makina owonetsera amagwiritsa ntchito mfundo yowunikira, mtunda pakati pa kuwala kowonekera ndi pakati pa chinsalu ndi wosiyana, ndipo malo a magwero atatu akuluakulu a kuwala kwamitundu mu chubu chowonetsera ndi wosiyana. Izi zimapangitsa kuti chithunzi chowonetsedwa chikhale chosavuta kukhalapo ndi kuchuluka kochepa kwa pixel defocus ndi m'mphepete mwamitundu. Kuphatikiza apo, chinsalu cha kanema chimagwiritsa ntchito nsalu yoyera, yomwe imachepetsa kusiyana kwa chithunzicho.
Ubwino ndi kuipa kwa mapulojekitala a LED
Ubwino:Ubwino waukulu wa ma projector a LED ndi wakuti nyali zawo zimakhala nthawi yayitali komanso kutentha kochepa. Ma LED amakhala nthawi yayitali nthawi zosachepera 10 kuposa nyali zachikhalidwe za ma projector. Ma projector ambiri a LED amatha kugwira ntchito kwa maola 10,000 kapena kuposerapo. Popeza nyaliyo imakhala nthawi yayitali ya projector, simuyenera kuda nkhawa ndi kugula nyali zatsopano.

Popeza ma LED ndi ang'onoang'ono kwambiri ndipo amangofunika kusinthasintha pang'ono, amagwira ntchito kutentha kochepa kwambiri. Izi zikutanthauza kuti safuna mpweya wambiri, zomwe zimawalola kukhala chete komanso ocheperako.

Nthawi yoyatsira ndi kutseka magetsi imathamanga kwambiri chifukwa sipafunika kutenthetsa kapena kuziziritsa. Ma projekitala a LED nawonso ndi opanda phokoso kuposa ma projekitala omwe amagwiritsa ntchito nyali zachikhalidwe.

Zoyipa:Vuto lalikulu la ma projector a LED ndi kuwala kwawo. Ma projector ambiri a LED amaposa ma lumens 3,000 - 3,500.
LED si ukadaulo wowonetsera. M'malo mwake ndi chizindikiro cha gwero la kuwala lomwe limagwiritsidwa ntchito.
