These include the colour filterless single lens projector illustrated in Figure 19.15.  <\/p>\n<p align=\"justify\">In this configuration, three dichroic mirrors are stacked in a non-parallel arrangement to split the white light beam into three primary colours beams. Alternatively, RGB angular separation may be achieved by <i>holographi<\/i><i>c <\/i>or <i>blaze<\/i><i>d diffraction grating<\/i>. The three beams are then projected onto a single LC LV from different incident angles. The LV pixels are divided into three RGB cells. A microlens array is used to direct the beams to their correspon- ding cells. The advantage of eliminating the colour filter is the recovery of  <\/p>\n<p align=\"justify\"><a href=\"http:\/\/lh3.googleusercontent.com\/-y4Chkhg26fM\/VeXMfGZ0zkI\/AAAAAAAB6TU\/-EvDiPmf_eA\/s1600-h\/Television-and-Video-Technology-0111%25255B1%25255D.jpg\"><img decoding=\"async\" loading=\"lazy\" style=\"background-image: none; border-right-width: 0px; margin: 0px auto; padding-left: 0px; padding-right: 0px; display: block; float: none; border-top-width: 0px; border-bottom-width: 0px; border-left-width: 0px; padding-top: 0px\" title=\"Television and Video Technology-0111\" border=\"0\" alt=\"Television and Video Technology-0111\" src=\"http:\/\/lh3.googleusercontent.com\/-TCiXZzTCCdA\/VeXMg8mGIQI\/AAAAAAAB6Tk\/6ZaivWxyVz8\/Television-and-Video-Technology-0111%25255B2%25255D.jpg?imgmax=800\" width=\"327\" height=\"227\" \/><\/a>  <\/p>\n<p align=\"justify\">light absorbed by the filter thus making the single-panel projector as bright as a 3-plane projector without the extra expense and size.  <\/p>\n<p align=\"justify\">Other technologies include the <i>polymer-dispersed LC <\/i>(<i>PDLC<\/i>) devices which scatter light but appear transparent when a high voltage is applied, <i>surface-stabilised ferroelectric LCs <\/i>(<i>SSFLCs<\/i>) which exhibits two states de- pending upon the polarity of applied voltage and <i>actuated mirror array <\/i>(<i>AM<\/i><i>A<\/i>) based on piezoelectric angular deflection of individual mirrors within an array and light amplifiers in which low-intensity image is amplified for high-intensity projection.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Merits and demerits of LCoS projection systems The merits include: \u25cf IC compatibility: The LCoS electronic substrate is compatible with the standard silicon technology, allowing additional driving circuitry to be integrated into the back-plane design. \u25cf Cost effectiveness for high resolution: LCoS can achieve HD resolution (1920 X 1080) in a 0.711 panel and 1280 [&hellip;]<br \/><a href=\"http:\/\/machineryequipmentonline.com\/video-equipment\/projection-systemsmerits-and-demerits-of-lcos-projection-systems\/\" class=\"more-link\" >Continue reading&#8230;<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[1],"tags":[],"aioseo_notices":[],"views":635,"_links":{"self":[{"href":"http:\/\/machineryequipmentonline.com\/video-equipment\/wp-json\/wp\/v2\/posts\/123"}],"collection":[{"href":"http:\/\/machineryequipmentonline.com\/video-equipment\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/machineryequipmentonline.com\/video-equipment\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/machineryequipmentonline.com\/video-equipment\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/machineryequipmentonline.com\/video-equipment\/wp-json\/wp\/v2\/comments?post=123"}],"version-history":[{"count":0,"href":"http:\/\/machineryequipmentonline.com\/video-equipment\/wp-json\/wp\/v2\/posts\/123\/revisions"}],"wp:attachment":[{"href":"http:\/\/machineryequipmentonline.com\/video-equipment\/wp-json\/wp\/v2\/media?parent=123"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/machineryequipmentonline.com\/video-equipment\/wp-json\/wp\/v2\/categories?post=123"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/machineryequipmentonline.com\/video-equipment\/wp-json\/wp\/v2\/tags?post=123"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
