Information on photoluminescence?

Click For Summary
SUMMARY

This discussion centers on photoluminescence and its application in projecting images using an LCD projector with a light intensity of 500 lumens. The user seeks guidance on optimal projection distance for achieving a contrast ratio of 20:1, particularly under varying room illumination conditions. Key factors include understanding the relationship between light intensity, contrast ratio, and projection distance, which are crucial for effective image clarity and quality.

PREREQUISITES
  • Understanding of photoluminescence principles
  • Knowledge of LCD projector specifications and performance
  • Familiarity with contrast ratio calculations
  • Basic concepts of room illumination effects on projection
NEXT STEPS
  • Research photoluminescence and its applications in display technology
  • Learn about calculating optimal projection distances based on light intensity
  • Explore contrast ratio standards and their impact on image quality
  • Investigate room illumination techniques to enhance projection clarity
USEFUL FOR

This discussion is beneficial for display technology enthusiasts, educators in optics, and anyone involved in optimizing image projection quality using LCD projectors.

Can anyone tell me any good websites which have information on photoluminescence?

Also, i have an lcd projector with a light source which has about 500 lumens as the light intensity.If i need to project an image of an chess board on the lcd onto the screen with the best contrast say for a 32 gray levels(5 bit) what shld be the distance to screen

Room illumination is the main factor you need to determine.
Also what do you consider to be an acceptable contrast ratio.
 
i am considering a contrast ratio of abt 20:1.i need some good material on this topic as i am very new to these.
