I-LED "i-Light Emitting Diode", iyunithi encinci yi-8.5 intshi, inokugcinwa kwepikseli kunye nokuguqulwa kwemodyuli yeyunithi, ixesha lokuphila kwe-LED ngaphezu kweeyure ze-100,000.

I-DLP yi“Digital Light Progression” ubukhulu obumalunga ne-50inch ~ 100inch, ixesha lobomi malunga neeyure ezingama-8000. zifuna ukutshintshwa kwihoseyile ukuba ibhalbhu ebonisayo kunye nephaneli zinengxaki.

1. Ukuziqhelanisa nokusingqongileyo kokuqaqamba

Ukukhanya kwe-DLP\LCD akukho phezulu. Ukukhanya kwe-Ambient kulinganiselwe ngokungqongqo; engafanelekanga iofisi yokukhanya okuphezulu okanye indawo yokulawula igumbi.

Ukukhanya kwe-LED kunokulungelelanisa phakathi kwe-600-1500cd, isuti yendawo eyahlukeneyo.

2. Isenzeko esizibonakalisayo

Isibonisi se-LCD, umphambili uxhotyiswe ngephaneli yesikhokelo esikhanyayo okanye esikhanyayo.

I-DLP kwisicelo esisebenzayo, iya kuba nesiphumo sokubonakalisa.

I-LED kuba iyiyunithi yokukhanya ezenzekelayo, kunye nephaneli emnyama ye-matte emnyama, indawo yesibane esimnyama, ngoko ke umbala wembonakalo yayo nayiphi na i-engile inokugcinwa injalo.

3. Jonga i-engile thelekisa

4. Isiphumo sokubonisa thelekisa

5. ukuthelekisa ratio thelekisa

I-LED isebenzisa isibane esikhokeleyo esimnyama, umphezulu wesikrini sisakhiwo sohlobo lokufunxa. phantse akukho mgca othe tye obonakaliswe ukukhanya, Ke umlinganiselo wokuchasana kwesikrini se-LED uphezulu njenge-4000: 1, yenza isikrini se-LED sibukhali kwaye sicace ngakumbi.

Uninzi lomlinganiselo wokuchasana weprojektha ye-DLP inokuba yi-600:1 ukuya ku-800:1, ixabiso eliphantsi nalo linokuba yi-450:1.LCD umahluko weprojekti yokulinganisa imalunga ne-400:1, kwaye ixabiso eliphantsi kuphela yi-250:1.

Udonga lwevidiyo ye-DLP

I-DLP kwiimfuno zokusingqongileyo ziphezulu kakhulu, ezifana nobushushu, ukufuma, uthuli, ukukhanya, njl., ngakumbi isikrini sesona sisengozini, ukukrazula umgca obhityileyo awukwazi ukucinywa kwaye ulungiswe, kukho ubunzima ngakumbi. ixesha liya kuphinda liyifunde kwakhona, kungenjalo umfanekiso uya kuzicima ngokuzenzekelayo. Umahluko wangempela we-DLP uphantsi kakhulu, ubonakaliswe kwindawo emnyama ebonisa iziphene, oko kukuthi, imifanekiso emininzi yemifanekiso emnyama ayicaci, le nto ibonakala ngokucacileyo. Njengokuba i-notebook ingabona indawo emnyama, kwisikrini se-DLP kumnyama, ayikwazi ukwahlula, ngoko xa isetyenziswe kwimifanekiso esweni, umgangatho womfanekiso uya kuncitshiswa kakhulu. Ubuthathaka beprojekti ye-DLP enye kuphela, oko kukuthi, "impembelelo yomnyama", ukusebenza okuthe ngqo kwahlulwa nje kumbala obomvu, oluhlaza kunye nohlaza okwesibhakabhaka lwe-monochrome emithathu, ijongeka njengemvula yomnyama.

Udonga lwevidiyo ye-LCD

I-disadvantage ecacileyo ye-LCD projector kukuba inqanaba elimnyama lihlwempuzekileyo kwaye ukuchasana akukona kakhulu.Umbala omnyama weprojekti ye-LCD uhlala ukhangeleka grey, kwaye inxalenye enomthunzi ibumnyama kwaye ingenazo iinkcukacha.Oku akufanelekile kakhulu kwividiyo yokudlala, into engalunganga kakhulu kumboniso bhanyabhanya, kodwa ayingomahluko mkhulu ngeDLP projektha xa udlala amagama.Impendulo yesibini kukuba isiphumo seprojektha yeLCD kukubonisa ubume bepixel, kwaye umbukeli ubonakala ejonga umfanekiso ilethi. I-SVGA (800 x 600) ifomathi ye-LCD yeprojektha, nokuba ingakanani na isayizi yomfanekiso weskrini, inokubonwa ngokucacileyo kwigridi ye-pixel ngaphandle kokuba kusetyenziswe imveliso enesisombululo esiphezulu. I-LCD ngoku yaqala ukusebenzisa uluhlu lwe-lens ye-micro (MLA), inokuphucula ukuhanjiswa kwefomathi ye-XGA yeepaneli ze-LCD, i-lattice diffusion ye-pixels, igridi ye-pixel efihlakeleyo kwaye engabonakaliyo, kunye nokubukhali kwemifanekiso akuyi kuzisa nayiphi na impembelelo. Inokunciphisa ubume be-pixel ye-LCD ukuba iphantse ifane neeprojekti ze-DLP, kodwa kusekho isikhewu.

HD inzuzo ye-LED

1.Ngaphezu kweeyure ze-100,000 zexesha lobomi

3.Ukusebenza kakuhle kombala

2.Ukusebenza okuphezulu kokutshatyalaliswa kobushushu

4.Ixabiso eliphantsi lokugcina

1.Ngaphezu kwe-10 0000 iiyure zexesha lobomi

2.Ukusebenza okuphezulu kokutshatyalaliswa kobushushu

Umphezulu osasazayo udityanisiwe, ubume beplate ye-aluminium, Ubushushu bomzimba wonke obuhambisa ubushushu, bunokuba yeyona nto ingcono yokulahla ubushushu;

I-Flank profile heat dissipation: Ubushushu obusebhokisini buthe saa ukusuka emacaleni, emva koko udibanise iipaneli, Kwiqokobhe elingasemva kumacala omabini okwenziwa kweendlela eziphezulu kunye nezisezantsi, ukusetyenziswa koxinzelelo lomoya ukwenza umoya ophezulu kunye nophantsi. umgaqo wokujikeleza, ukuchithwa kobushushu ngokupheleleyo.

3.Ukusebenza kakuhle kombala

Umgaqo wokubonisa we-RGB wokukhanya okuzenzekelayo ugcina ukunyaniseka kombala, ukuphepha ukulahleka kombala kunye nokuphambuka okubangelwa zizinto eziphathekayo kunye nokukhanya okuhambayo kwindlela yokukhanya kunye nokukhangela.

I-YWTLED Yonke kwi-LED enye -I-TV yiyunithi yokukhanya ezenzekelayo, enepaneli ephantsi ye-matte emnyama, umphezulu omnyama we-bead, ukuze ukusebenza kombala kuyo nayiphi na i-engile ebonakalayo igcinwe injalo.

4.Easy ukugcinwa

Iindleko zokulungisa eziphantsi

Iyunithi yomgangatho we-LED, iphaneli yokubonisa yenziwe ngeeyunithi ezincinci; iipikseli zokubonisa zenziwe ngesibane se-LED.

Ukuba kukho indawo ye-necrotic, yitshintshe ngeyunithi esecaleni kwaye ulungise isibane se-LED;

Ukuba indawo yolawulo ibonakala ingafumaneki, indawo yolawulo encinci yokubonisa inokutshintshwa;

Ngokomzekelo, indawo yokubonisa i-intshi ye-32 yi-4% kuphela yepaneli yendabuko.

I-mainstream yangoku yiyunithi ye-46-intshi, i-55-intshi, kunye ne-60-intshi ye-splice unit, kunye nexabiso eliphantsi lokulinganisa.

I-LED akukho mahluko emva kokulungiswa kweyunithi

Xa ubuyisela i-LED enye, unokukhetha isibane se-LED esigcinwe kwimveliso. kunye nokukhanya kokulungiswa kwendawo enye kunokuqhutywa ukuyigcina ingaguquguquki;

Xa ubuyisela imodyuli yeyunithi, yonke imodyuli kunye neepaneli zisetyenziselwa ukulungiswa okufanayo, ukwenzela ukuba ukushisa kombala kunye nokukhanya kuhambelane nemeko yangoku yesikrini seprojekthi.

Udonga lwevidiyo ye-LCD Umahluko omkhulu emva kokulungiswa kweyunithi

Umbala weyunithi yokutshintsha kunye nokuqaqamba zonke zikwimeko entsha, akukho kuncitshiswa, kufana kakhulu kwaye kuqaqambile;

Kwaye ezinye iiyunithi zangaphambili, emva kokusetyenziswa kwexesha elide, ukuqaqamba kokukhanya kunye nescreen kunye nezinye izinto, njengokuguquguquka komgubo okhanyayo, umbala kunye nokuqaqamba kwehle kakhulu;

Kukho umahluko omkhulu kwiziphumo zokubonwayo ngokubanzi.
