- Flicker
- Impact of a Flickering Display
- CFF 60 Hz/50 Hz
- Recommended flicker rates between 66 Hz and 120 Hz (Bridgeman, 1998)
- Light levels and display size impact CFF
- Depends upon length of off cycle (very short in LCD longer in others)
- Flicker vs Update Rate - an aside on High Frame Rate Movies
- 5 Hz
- 10 Hz
- 15 Hz
- 20 Hz
- 30 Hz
- Flicker is not the same as Apparent Motion
- The shorter off time of LCD displays leads to motion blur
- Examples:
- LCD
- CRT
- Color/Color Gamut
- Let us look back at the CIE Diagram
- What colors can the diplay really reproduce?

- Summary
- Displays are highly variable
- They impact what is experimence
- We are saved to a large extent by the fact that the eyes work as a contrast engine
- We don't see point by point
- We see how one area changes relative to next area
- However, design for good contrast and simple arrangments to avoid the subltlies where these issues can be problematic
