HP-35s current production line question



#11

I purchased an early production HP-35s, not long after they were introduced. I am curious if HP has addressed the somewhat highly reflective plastic LCD cover in current models? The glare has presented quite a problem in my present working environment. I just borrowed an HP-33s from a colleague and it seems to provide better viewing contrast (at all viewing angles) compared to my HP-35s.


#12

I have a pretty new 35s and unless I position it so a light is reflecting directly off the screen, I can read it just fine, much better than my 50g.

Have you adjusted the contrast? Hold down the ON key and the + and - keys to adjust it.

Dave


#13

Jaime means the plastic lens itself reflects so much it's difficult to see at nearly any angle and contrast isn't the issue. I have the same gripe with my 35s (also an early production run). The 35s has about the most reflective lens I've seen in any HP calc, definitely much worse than my 33s, 32SII, 41C or 48G.

#14

I bought an anti-reflective film for my new laptops. (New laptops are as useless as _______the screens are so reflective!)

This aftermarket film works GREAT!

NuShield DayVue is what I use, and it really does work outside. Without the film, I cannot use my laptops at all outside. They also make an indoor film, which I have not tried but it might work well for you. I called them and they were very helpful.

One does have to wonder why we need aftermarket products to able to use our equipment, but that's they way it is...like going to toys r us to buy baby carseats...

Actually, HP should license the technology and put it on all their calcs...

Matte films for GPS units, digicams, etc.. can be found
where such are sold and are relatively cheap.

The only possible drawback is it will reduce contrast somewhat
and the 35c matrix lcd doesn't have much of a budget surplus
here at least to my eyes.

It is fairly common for the top polarizer of an lcd to have
some glare reduction. Unsure why that wasn't the case for
the 35c. Although IIRC there is an outer window above the
lcd in the 35c which is what needs this treatment. One
could toss that and mount the adhesive matte film directly
to the display.


#16

The film I bought is not a "matte film." In fact it is somewhat glossy--but anti-reflective. It is much much more effective than a matte film. It actually works in bright light, because it does not scatter, it cancels reflections.

#17

I went ahead and opened my HP-35s and removed the plastic window that is in front of the LCD. The glare was way too much for me and I'm willing to live with whatever risks are associated with the plastic cover being removed. However, it looks as though I could replace it with something less reflective (cut to size) if I wanted to, but I am happy with the present results.

The risk being scratching of the top polarizer. It certainly
can be replaced but it is a bit of a pain to find a replacement
and get it laminated to the glass without trapping dust
in the lamination.

I'd just get an inexpensive camera/GPS screen anti-glare shield
and cut a section sized to replace that gawd awful original window.


#19

I agree, the plastic polarizing overlay is a bit fragile. I went ahead and put an anti-reflective overlay directly onto it. I used a spare sheet of AR film meant for an iPod and cut it to size. With the plastic LCD cover removed, it now looks great...NO GLARE and good contrast!!!

Forgot to mention.. if you were to replace the upper polarizer,
you could rotate it 90* to the achieve the inverse effect of
white-text on a black-background. Just in case anyone may be
into customization.
