This blog is the follow-up to my earlier blog from before the CEDIA show. That earlier blog was from August 31 and was titled “Screens for 3D Projection – Part 2”. This new blog will be my wrap up, for now, on projection screens for 3D, but I’m certain there will addition future blogs that will cover the topic of screens. Read the rest of this entry »
This blog provides a preview of new projectors expected to be introduced at the annual “Custom Electronics Design and Installation Association” (CEDIA) Expo that runs from 7 – 10 September in Indianapolis. This is the trade show where most manufacturers of home theater oriented projectors, screens, high-end audio gear and home automation systems introduce/demo their new and upcoming products for the North American market. Several of us associated with Projector Reviews will be attending the CEDIA Expo and my next blog will report on what new projectors were being shown and provide impressions from some of the demos.

This blog is a continuation of my previous blog. These discussions focus on factors that need to be considered when selecting a projection screen for use in a home theater with a 3D projector. While many of the screen characteristics equally apply to selecting a screen for regular 2D projection, there are some factors that are either more important when it comes to 3D or apply only for the case of 3D.

For this Blog I am starting off with some additional info related to 3D active shutter glasses then I am begining (i.e., Part 1) a discussion on things to consider when selecting a screen for use with 3D projectors. Read the rest of this entry »
For this blog I will be discussing 3D active shutter glasses.
As touched upon in earlier blogs, there are basically two general categories of glasses used for viewing 3D video. The simplest form is “passive” which use left and right lenses that either have a different fixed polarization or pass different portions of the light spectrum (e.g., different colors). Most consumer 3D TVs and 3D projectors require the use of the more complex “active” shutter 3D glasses and this latter category is the subject of the discussion below. Read the rest of this entry »
D-ILATM Based 3D Projectors
This is the second part of my blog on using LCoS 3D projection technology. We are currently talking about 3D projection using sequentially alternating right/left images and where viewers must wear active shutter 3D glasses. For this blog I will focus on the JVC D-ILA approach used for 3D. Read the rest of this entry »
For this blog I will focus on 3D projectors based on Liquid Crystal on Silicon (LCoS) technology for which the viewer must wear 3D active shutter glasses. As discussed in my previous blog, this type of 3D projector alternates the display of right and left images that are synchronized with the liquid crystal shutter lenses of the viewer’s 3D glasses such that the right eye only sees the stream of images intended for that eye (i.e., the right image stream) and the left eye only sees the left image stream. LCoS is one projection technology that can be used to create such a 3D projector.
