Hello,
I'm looking at getting a Toshiba M35 or M45. I really want a nice bright, clear screen. I know the display on the M35 is supposed to be pretty good, I was just wondering if the M45 with the TruBrite is that much better. What are the real differences? Thanks in advance.

Trust me, it IS bright
And the viewing angles are astonishing.

in order to know the benefit of trubrite, you need to know how it works.
the theory is simple; the more transpareant a surface is, the more light will travel through it.
if you look at a LCD screen without trubrite, you'll notice that the surface seems hazy and the texture feels like a matte finish to the touch. on the other hand, trubrite screens are clear, glossy, and feel like glass to the touch.
the difference is that non-trubrite screens have higher and more (microscopic)bumps on the surface of the screen. these bumps reflect light that's produced by the LCD which is trying to reach your eyes. since trubrite screens are flatter, they reflect less light, allowing more light to reach your eyes. more light = brighter screen.
place a trubrite LCD beside a non-trubrite and you'll notice that the colors on the trubrite are much more vivid. since colors are also light rays that reflect off objects and enter your eyes, more light means brighter, sharper colors. this doesn't mean that the colors on trubrite screens are wrong, different or brighter than what they are supposed to be. these colors are actually more true to what they should look like, and colors of a non-trubrite LCD appear slightly lighter(washed out) than what they should be.
viewing angle is also improved with the clarity of the screen, because more light from the LCD is reaching your eyes regardless of the angle you are viewing from.
the final issue is glare. most people get the impression that there is more glare from trubrite screens than regular screens. glare is basically reflected light that's not coming from the LCD. it could be from the sun, a desk lamp, whatever. what needs to be understood is that glare from a trubrite screen and a non-trubrite screen are different.
on a regular LCD screen, more ambient light is reflected off of the surface due to the bumps. this explains why the screen seems hazy. no matter where you move your head, each bump is always reflecting light towards many different angles. at the same time, because the light is being reflected to many different angles, the glare is never as intense as a trubrite screen. a trubrite screen will only have glare when the ambient light source is at such an angle that it reflects into your eyes. however, because the screen is more clear and transparent than a regular LCD, it is easier for the light to travel through the screen surface and reflect off of the back of the LCD. due to the lack of bumps on the surface, any light that's been reflected is pretty much headed towards your eyes with full force.
in the end, you'll see less glare on a trubrite screen, but the glare will be more bright and intense when you do see it. same thing applies for reflections off LCDs.
this is a little long but hopefully it'll be informative for some. the best way to see the difference that a trubrite screen makes is to see for yourself.
and no, I'm not being paid to say this stuff. []

Great post! Thank you for taking care of an explanation long&clear! [as clear as a Trubrite glass may I say? [
] ]
Toshiba TruBrite for real?
