I-LCD imele "I-Crystal Display Display". I-teknoloji yeLCD iye yahlala nathi kwiminyaka emininzi kwaye isetyenziswe kwizicelo eziboniswayo zevidiyo, kuquka ukuboniswa kweepaneli kwiixhobo zombane kunye nezixhobo zombane zombane, kunye nokubonakaliswa kwedijithali. Mhlawumbi ukusetyenziswa okuqhelekileyo kubabasebenzisi kusetyenziswa kwiTV .
KwiiTV, ii-LCD chips zihlelwe ngaphantsi kwesikrini kunye nokusebenzisa umbane ( uhlobo oluqhelekileyo luyi-LED ), ii-TV ze-LCD ziyakwazi ukubonisa imifanekiso. Ngokuxhomekeke kwisisombululo sesiboniso seTV, inani leetayili ze-LCD ezisetyenzisiweyo zingabalwa kwininzi (iplastiki nganye yeLCD imela ipixel).
I-LCD Sebenzisa kwiProjection yevidiyo
Nangona kunjalo, ngaphezu kweTV, i-LCD Technology isetyenziswa kwiiprojekti ezininzi zevidiyo. Nangona kunjalo, esikhundleni sokuba nenani elikhulu lama-LCD aphethwe ngaphaya kwendawo yeskrini, iprojekti yevidiyo isebenzisa 3 i-LCD Chips eyenzelwe ngokukhethekileyo ukudala nokwenza imifanekiso kwi-screen yangaphandle. Iintlobo ezintathu ze-LCD nganye ziqulethe inani elifanayo leepekseli ezilinganayo nesisombululo sesiboniso seprojekti, ngaphandle kweendlela zokuguqula iipilisi ezisetyenziswa kwezinye iiprojekti zevidiyo ukuba zibonise isisombululo esiphezulu "umfanekiso o-4K" ngaphandle kokuba nenani elifunekayo lamaphikseli .
3LCD
Olunye uhlobo lwekhompyutheni yokuqulunqwa kwevidiyo ye-LCD lusetyenziswa njenge-3LCD (ukuba ingadityaniswa ne-3D).
Kwiinkqubo ezininzi ze-3LCD, umthombo wokukhanya wesibane uthumela ukukhanya okumhlophe kumhlangano we-3-Dichroic Mirror odibanisa ukukhanya okumhlophe kwiimitha ezibomvu, eziluhlaza neziluhlaza, eziye zadlula i-LCD chip ezintathu ze-chips (enye ekhethelwe umbala ngamnye oyintloko). Imibala emithathu idibeneyo isebenzisa i-prism, idluliselwe ngqungquthela ye-lens ize ilandelwe kwesikrini okanye udonga.
Nangona imithombo yokukhanya esekelwe kwizibane isetyenziswa kakhulu, ezinye iprojekti ezi-3LCD zingasebenzisa umthombo we- Laser okanye i-Laser / LED-based based light , endaweni yesibane, kodwa umphumo wokugqibela unye-umfanekiso uhlolwe kwisikrini okanye udonga.
3LCD Iimpawu ezihlukeneyo: i-LCOS, i-SXRD kunye ne-D-ILA
Nangona iteknoloji ye-3LCD yenye yezobuchwepheshe obuqhelekileyo ezisetyenziswayo kwiiprojekti zevidiyo ( kunye ne-DLP ), kukho ezinye iinguqu ze-LCD-based. Uhlobo olufanayo lwemithombo yokukhanya (iLamp / Laser) isenokusetyenziswa kunye nale mihluko yeLCD.
I-LCOS (i-Crystal Crystal kwi-Silicon), i- D-ILA (i-Digital Imaging Light Amplification - esetyenziswe ngu-JVC) , kunye ne- SXRD i- Silicon Crystal Reflective Display - esetyenziswe ngu-Sony), idibanisa ezinye iimpawu zombini lwe-3LCD kunye ne-DLP.
Ziziphi izinto ezihlukeneyo ezintathu ezifana ngazo kukuba esikhundleni sokukhanya okudlula kwii-chips ze-LCD ukwenza imifanekiso njengeteknoloji ye-3LCD, ukukhanya kukhankanywe kwi-chips ye-LCD ukwenza imifanekiso. Ngenxa yoko, xa kuziwa kumzila wokukhanya, i-LCOS / SXRD / D-ILA ibizwa ngokuba yi-technologies "yokubonakalisa", ngoxa i-3LCD ibizwa ngokuba yi "teknoloji".
3LCD / LCOS Inzuzo
Enye yeenzuzo eziphambili zeentsapho zeLCD / LCOS zobuchwephesha bokuboniswa kwevidiyo kukuba zombini umgangatho omhlophe kunye nombala wokuvelisa ufana. Oku kuyahlukana neTheknoloji ye-DLP leyo, nangona inamandla okuvelisa umbala obalaseleyo kunye namanqanaba amnyama, ayikwazi ukuvelisa zombini umbala omhlophe nombala kumgangatho ofanayo apho iprojekti isebenzisa isondo lombala.
Kwiinkqubo ezininzi zeprojekti zeDLP (ngokukodwa ukusetyenziswa kwekhaya) ukukhanya okumhlophe kufuneka kudlule ivili lesiguqu eliqulethe amacandelo aBomvu, aBluhlaza kunye neeBlue, okunciphisa inani lokukhanya elivela kwelinye icala. Ngakolunye uhlangothi, iiprojekti zeDLP ezisebenzisa ubuchwepheshe obungenawo umbala (njenge-LED okanye i-Laser / i-LED imithombo yokukhanya ye-Hybrid okanye imodeli ye-3-chip) ingavelisa inqanaba elifanayo lemveliso emhlophe nombala.

3LCD / LCOS Iingxaki
Iprojekti yeLCD isinokubonisa ixesha elibizwa ngokuthi "umnyango wesikrini". Ekubeni iskrini senziwe ngamaphikseli athile, iipikseli ziyakubonakala kwikhrinta enkulu, ngaloo ndlela zinika imbonakalo yokubukela umfanekiso "ngomnyango wesikrini".
Isizathu salokhu kukuba iipekseli zihlukaniswe yimida emnyama (engeyiyo). Njengoko ukwandisa ubungakanani bomfanekiso oqingqiweyo (okanye ukunciphisa isisombululo kwisayizi efanayo neskrini) umda ngamnye wepikelel uyakwazi ukubonakala, ngaloo ndlela unike imbonakalo yokubukela umfanekiso "ngomnyango wesikrini". Ukuphelisa le mphumela, abakhiqizi basebenzisa ubuchwephesha obuhlukeneyo ukunciphisa ukubonakala kweemida ze pixel ezingenamthetho.
Ngakolunye uhlangothi, kwiiprojekti zevidiyo ezisekelwe kwi-LCD ezinokukwazi ukubonisa ukulungiswa okuphezulu ( 1080p okanye ngaphezulu ), le mpawu ayibonakali kuba iipekseli zincinci kwaye imida iyancipha, ngaphandle kokuba usondele kakhulu kwesikrini, kwaye isikrini sikhulu kakhulu.
Omnye umcimbi onokuza (nangona kunqabile kakhulu) nguPixel ukutshiswa. Ekubeni i-LCD chip eyenziwe yiphaneli yamaphikseli athile, ukuba i-pixel enye iyatshisa ibonisa inkxalabo ebumnyama okanye emhlophe ecatshulwa kumfanekiso oqikelelweyo. Iipekseli zodwa azikwazi ukulungiswa, ukuba enye okanye ezininzi iipekseli zitshatyalaliswe, zonke iip chip kufuneka zitshintshwe.
