You might try one of these instead of the cellphone:
Without the LCD and polarizer in the way, it should be much brighter.
And for three and a half bucks, the price is right.
Nice and thin, even illumination. Use a blue gel filter if you really need just blue light.

--As you guys probably know, I have been working on a super low cost gel system. As part of my research on the box, I tested as many types of gel illumination as I could afford. Among the tech used were:
1W blue led
8x8 rgb led matrix
12 v blue led strip (intended for cars)
3x4 blue led matrix
4x4 electroluminescent Panel
Cell phone screen (samsumg Galaxy note ii)
Computer screen (dell e6410)
2x regular (through hole) LEDs.
I have written up my findings and comparisons on my blog, here. I is quite image heavy.
