  3. 3. Jenmar BlackScreen® The Future of Better by Contrast Rear Projection Agenda The Ideal Display. Where Did RPTV Go Wrong? Where Did RPTV Go Wrong? What Does RPTV Need?  What Does RPTV Need? Jenmar and Its Contributions. Conclusion
  4. 4. Jenmar BlackScreen ® The Ideal Display Better by Contrast The Ideal Display The Ideal Display Brightness Resolution Contrast Saturation Viewing Angles Scales to Large Sizes S l L Si Low Cost All in Normal or Elevated          Ambient Light
  5. 5. Jenmar BlackScreen ® The Ideal Display Better by Contrast The Ideal Display (Continued) The Ideal Display (Continued) Thin Can Be Tiled (Video Wall) Can Be Tiled (Video Wall) All in Normal or Elevated          All in Normal or Elevated Ambient Light
  6. 6. Jenmar BlackScreen ® The Ideal Display Better by Contrast In Each of These Key Areas In Each of These Key Areas Rear Projection Has Advantages. Brightness Scalable Resolution LCoS & BlackScreen® Contrast BlackScreen® Saturation BlackScreen® Viewing Angles Viewing Angles Lambertian Large Size Scalable  (Cost per unit area decreases with size)    Low Cost C Lowest cost in all but the smallest sizes i ll b h ll i
  7. 7. Jenmar BlackScreen ® Where Did RPTV Better by Contrast Go Wrong? Narrow Vertical Viewing Ignoring Ambient Light Retreating to Large Screens as the  i h Only Differentiator Lack of a champion
