blue LED's on radio are displays a bad idea
The whole point of radio backlights is to make the display visible in the
dark. I noticed that there is a trend towards blue LED's, and this is a very bad idea. Degen's DE-1102 radio uses these, and also Radiolabs has a modified ATS-909 that uses a blue backlight. Grundig also has a number of products which appear to use blue backlighting or keyboard lighting. I imagine pretty much all future portables will be like this. I have a DE-1102 myself, and I find that the backlight is pretty much useless, as although it does allow me to see the display, the blue light kills my nightvision, and also the blue LED's used are rather dim compared to traditional orange LED's that could be used. I find that other radios I have had, with orange lighting, are much easier to read in a hurry. The blue color is also closer to the black color of the LED lettering, which doesn't help. An example of this tomfoolery: http://www.radiolabs.com/images/prod...thumb_mask.gif I don't know what other manufacturers are doing this, but I really wish they would stop. I guess this is what happens when design teams get compromised by marketing. --- swap "hotmail" and "com" to reply by email. |
Why not white LEDs?

I too don't think it is as optically affective as amber backlighting, but it sure looks neet :-) Perhaps a radio manufacturer needs to do what The Ford Motor Company is going to do about backlighting. On the 2005 Musang, there is going to be a color configurable backlight for the dash instruments. You will be able to adjust it via a control button to mix and match color tones to create up to as many as 125 different colors of backlights. LOL.... So.... How about it ???? A 7600gr or YB-400 with mix and match backlighting up to 125 colors ??? Michael |
I noticed that there is a trend towards blue LED's, and this is a
very bad idea. I can't agree. I like blue backlighting, if it's not too dim. Not owning a DE1102, I can't 'disagree' with your experience with its backlight, and wouldn't pretend to. Perhaps it is too dim for you, not so for others. I always like to modify and adjust the backlights on my radios anyway, if the stock display is fatiguing or annoying. You may wish to go into your DE1102 and change those LEDs to amber or some warmer, brighter color which serves your eyes better than the stock blue does. I find myself going the opposite direction, for example, the stock amber/orange LEDs on my R75 were always glaringly annoying to me, so I eventually changed them to green, then reversed the polarization filter on the LCD so that now it's a dark background with bright alphanumerics, and THEN I swapped out the green LEDs for white LEDs, which gives a sort of dark/deep blue background with white alphanumerics... and in front of this, I can use any color of filter I want, so one day it's red, another green, blue, purple, whatever suits me that day. Now THAT is a flexible display modification, and has given me much better results and avoidance of fatigue or eyestrain. I've never liked amber/orange backlights much, so most of my display modifying has been predicated on that personal taste. But that's just me. Linus |

Well, at least it's not a brilliant one. If you want to illuminate something without using too much valuable battery power, you best do that with an LED that emits light in a spectral range where the human eye is most sensitive (in darkness), so you can use one with less output power. This would be roughly around 550 nm, with a tendency to higher wavelengths as it gets darker. So in theory, something yellow to greenish should be ideal, maybe also orange. In fact, Sony portables use green backlighting.

I don't remember ever having an orange LED... Guess I don't get out much, or you're color blind maybe?? - This is what I was thinking.. Possibly Color deficient ?? |

I removed the green LED's in the array and replaced them with four white ones located in holes I made in the ends of the display frame. The display background is now aqua/blue with white charecters. I like it much better than the original all green display. -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |

Agreed, I did a DX-390 with nice BRIGHT- blue but lettering looked fuzzy at
that end of the spectrum to me. Orange is best, Remember high brightness LED have a narrow beam's and you dont have much room to work with Cut the lens off the LED + wet sand as close to the chip's as possible.. This gets the beam wide and diffused for better illumination in the LCD display. Tie in at the audio IC with a series resistor I wish they would make radios and scanners with a motion sensor illumination. -Joe "RHF" wrote in message om... "Michael" wrote in message et...
