#SILVER SCREEN PROJECTOR FULL#
This was done since it has been observed that the JVC 3D projectors, with their DILA (LCoS) micro-display panels produce far less crosstalk after they heat up to full operating temperature. To evaluate the level of crosstalk present when using my DLA-RS40 along with my JVC 3D active shutter glasses I first allowed the projector to run for approximately 60 minutes in high lamp mode. Any visible crosstalk will result in a dim (very dark grey) vertical bar being visible through the left lens of the 3D active shutter glasses while if there were no crosstalk the image on the screen would appear fully black when viewed through the left lens of the 3D active shutter glasses. This generally represents the most demanding situation for 3D and with most 3D projection systems will be the most likely to produce visible 3D crosstalk/ghosting. Of the 3D test patterns I have created the one most appropriate for testing of 3D crosstalk is where the left image is solid black while the right image has a 100% white vertical bar on a black background (see photos below).
Note that the RS40 has just very recently been replaced in JVC product line by the new DLA-RS45 which has been reported by a few new owners to have similar 3D performance to the RS40 (in one case when both were viewed side-by-side). My home theater projector is a one year old JVC model DLA-RS40. This disc provides full resolution 1080p/24 test patterns and is encoded using the Blu-ray Disc standard 3D “frame packing” format. In order to test for 3D crosstalk I have created a Blu-ray 3D test disc that includes a number of 3D related test patterns. In Part 1 of my blog (December 14, 2011) I discussed the potential sources for 3D Crosstalk/Ghosting with 3D projection systems, including both active and passive 3D projection technologies. 3D Crosstalk/Ghosting Results for my JVC DLA-RS40 Projector
For the continuing discussion from my most recent blog on 3D Crosstalk, I have now completed measurements of the 3D crosstalk level from my JVC DLA-RS40 projector and for the further discussion on screens for 3D projection I have taken a quick look at sample “silver screen” materials from both Stewart and Da-lite that are being marketed for use with passive 3D projection systems, that use polarization for their 3D separation, as well as suitable to 2D projection. This blog is a continuation of my previous blog ( HERE) of Decemon “3D Crosstalk/Ghosting – Part 1” and also is a follow-up to my earlier blogs discussing screens for 3D projection (i.e., blogs from August 19 th, August 31 st, and December 1 st.
