How does Toshiba TruBrite work?

[computercpu]

Hello guys! So as you can see from the topic I'm wondering what kind of a technology is Toshiba TruBrite? Is it a feature that makes the image on the laptop's screen look and perform better in bright and sunny conditions or what actually is it? The laptop's screen comes with a glossy finish and a Full HD, ISP, LED-Backlit + Toshiba TruBite technology.

My second question is that how would this glossy finished screen with all these "fantastic" features perform in a bright sunny day outside? Would I still be able to pretty much clearly see the stuff on the screen without major reflections of my face and the sunlight from the screen or not?

Thank you for your kind helpfulness!!!!!

Background of Toshiba TruBrite™

TruBrite™ is Toshiba’s trademarked marketing name which represents the latest in anti-reflective LCD screen technology (anti-reflective technology).

Anti-reflective LCD technology was first introduced in early 2003 to the Japanese notebook market. This technology became an instant hit due to image clarity and brilliant colors of this high-gloss screen. This new technology is higher in contrast, produces clearer and more colorful images and has wider viewing angles than standard notebook screens.

Anti-reflective LCD technology is not a proprietary technology of Toshiba. In fact, most screens installed in Toshiba Qosmio, Satellite, Tecra and Portege notebooks are not manufactured by Toshiba. Toshiba, like other laptop brands, procures notebook screens from LCD screen manufacturers. It is these LCD screen manufacturers that produce this anti-reflective LCD technology. Toshiba merely purchases and installs both anti-reflective and typical LCD screens in their Toshiba notebook models. Those Toshiba notebook models using anti-reflective technology are marketed under the Toshiba TruBrite™ brand.

In addition, the anti-reflective technology marketed as Toshiba TruBrite™ is identical to the anti-reflective technology being marketed as Sony XBRITE™, HP Compaq BrightView as well as names marketed by other notebook brands.

The Technical Stuff
(Click here for a more detailed explanation including diagrams)

All notebook screens have a polarizer which is a thin layer of film laminated to the outermost layer of glass of the notebook screen used to filter light waves produced by the screen to generate an image. The difference between a typical notebook screen and an anti-reflective notebook screen is the type of polarizer.

The polarizer of a typical notebook screen has a rough matte surface which is not visible to the naked eye. This matte surface causes external light to diffuse or reflect off at different angles which reduces the intensity of light reflected directly back to the viewer’s eye. The side effect of the matte surface is distorted images, lower contrast ratio, narrower viewing angles and increased eye fatigue to name a few.

The polarizer of an anti-reflective Toshiba TruBrite™ screen and its equivalents have a smooth chemically-treated surface. The chemically-treated surface of the polarizer reduces ambient light reflection by absorbing most of the external light instead of diffusing it at different angles. Since the external light is mostly absorbed instead of reflected at different angles, it does not need a rough matte surface and therefore a smooth surface can provide crisp, brilliant-colored images with the most direct internally derived light from the LCD.

In general, the observer sees light from two light sources: 1) light generated by the LCD specifically and 2) external ambient light which is reflected off the surface of the LCD. The objective of an anti-reflective polarizer is to amplify the light generated by the LCD while minimizing the reflection of external ambient light.
