Bill Crocker -------------------------------- A frined's uncle was a enginner at HP and worked on their first LED calculator. They ran into an odd problem. The durves that showed the visual response of the human eye where not all that good. Many men had major problems first LEDs displays they made if there was any room light. A rapid reformulation of the LEDs saved teh day. Many men can not see nearly as deep into the red as the charts still show. And a few can see well into IR. I have no idea how a females eyes respond, but I suspect the same data appplies. They were con cerend with males, because that is who bought the early calculators. I do know that most women as a gerenal rule can discern subtle color variations that most men can't. This relates to LASER pointers. Human vision has a fairly fast drop in response at the red end, and only a few nM in wavelength can make a LASER lose a lot of apparent brightness. The deeper reds LASES are much cheaper then the higher red LASERS. Terry |

I could see green l.e.d displays fine, but red was out of focus. I had to get the prescription changed to correct the problem. |

The backlight is awful. The contrast is bad, and the color HURTS
I'll bet either Uniden will have to re-do these, or there will be a cottage industry in retro-fitting an orange or green LED On Wed, 29 Jun 2005 21:35:23 -0400, Bob wrote: I agree, green is fine, as are red and yellow.
