Sharing the battery tests on the Q1P earlier today led to quite the revelation: Samantha appears to have an LED backlight. Weren’t we just discussing that technology yesterday? It’s already made an impact on my mobile device because the Q1P looks to get at least an hour more of runtime over the original Q1. So, aside from the potential power savings: how does the screen look?

Above are both devices with the Brightness setting on each set to the minimum. Sammy with the standard backlight is on the left and looking kinda dim. Samantha is on the right, and if we’re correct, is providing vibrant color and brightness using LED backlighting. I stepped through some brightness settings and have a trail of pictures to illustrate the difference.

Brightness_med_low
Sammy now has 50% brightness while Samantha is still at the lowest setting. To the eye, these are pretty comparable.

Brightness_med_med
Both units are now at 50% brightness.

Brightness_full_med
Sammy gets boosted to full brightness while Samantha is unchanged at 50%. Again, these are comparable to the eye.

Brightness_full
Both units running at full brightness.

If we do the math and compare 200 nits against 280 nits, it comes out to a 40% brightness boost. That makes sense since the Q1 at full brightness looks similar to the Q1P at 50% brightness. Add that to the benefit of around 40% to 50% more runtime if the test was right and this device looks even more attractive. I’ll be peforming more tests to validate and verify what we’ve seen so far.

The shame of this is: the product page for the Samsung Q1P only states that the screen is 280 nits of brightness; if that’s due to the LED backlighting, why not mention that in the specs?

  1. You’re right. Samsung have really missed a trick.
    If they want to sell a device, they should highlight the advantages. A 4 hours battery life is a huge one!!!!

  2. That’s an amazing difference; either more visibility in daylight or a nice extension to battery life. It makes the jump in price a bit more understandable on the Q1P, too; LCD isn’t expensive, but it ain’t as cheap as cold cathode either. Once again Samsung stays quiet on a desirable feature rather than bring it out as a genuine competitive advantage. *sigh*

    (The Q1P is looking really nice, but I’m still keeping my aulden Q1.)

  3. Hope springs eternal that Samsung used that same energy saving screen on the Q1b (it sure looks that way from Samsung’s less-than-informative web page). With its battery sipping Via processor, that should go forever on a charge! Wasn’t UberTablet reviewing that unit?

    WOW. That is a big difference.

    So is Sammy jealous of Samantha’s screen?

  5. so how did we figure out it has led backlighting?

  6. Kevin,now you’re nitpicking again. :)

    But is it now usable outdoors? The Q1 certainly isn’t.

  8. …just open your device and if you can’t see any inverter connected to screen, it uses leds ;)
    Inverter in q1 is about 1cm x 10cm pcb with 2 silicon cables connected to screen..

  9. Yes, what about outdoors?!??

  10. but my q1 is sometimes even too bright for me at the lowest setting! this way the q1p would be unusable in very low light conditions (a dark room e.g.).

    if it would make the q1 usuable outside on a sunny day, I could live with it, though…
