MTF Revealed – Part III : JVC RS35 Update – The Secret Ingredient?

December 28, 2009 In part II of this series, we explored sharpness differences between LCOS and DLP technologies.  In that article we also speculated that there appeared to be some unique changes to the JVC RS35 that improved sharpness and perhaps reduced chromatic artifacts as well. In this article we take a closer examination of...

MTF Revealed – Part II:  JVC DILA (RS35, RS20, RS1) vs DC4 DLP

December 22, 2009 In Part I of this series we examined the Samsung SP-A900B projector. This projector uses the larger .95″ DC4 DMD, it has excellent optics across the field and it is relatively free of chromatic aberrations and geometrical distortions. Since it is a single chip DLP design, there is no reduction in sharpness...

LCOS vs DLP, .65″ DC3 DMD vs .95″ DC3 DMD – The Sharpness Debate

June 21, 2009 Frequent debate and speculation has centered around the sharpness differences between DLP and LCOS display technologies.  Unfortunately these comparisons are complicated by factors such as 3-chip panel convergence errors, lens quality and chip size.  Often, these debates have compared images from single chip DLPs with no convergence errors, larger chip sizes (.95″ for most commercial DMDs)...
