What is HP or Compaq BrightView?
HP Compaq BrightView Background
BrightView is HP Compaq’s marketing name for its latest in anti-reflective LCD screen technology.
Anti-reflective LCD screen technology was first introduced in early 2003 to the Japanese consumer laptop market. This technology was instantly successful because of its image clarity and its vivid colors. This new technology has higher contrast ratios, produces crisper and more colorful images and has wider viewing angles than a traditional notebook screen.
High-gloss, anti-reflective LCD screen technology is not proprietary to HP Compaq. In fact, LCD panels installed in HP Compaq OmniBook, Pavilion, Presario, Evo, Armada and Business Notebooks PCs are not manufactured by HP Compaq. HP Compaq, like other laptop makers, purchases LCD screens from LCD screen manufacturing companies. It is these LCD screen manufacturers that manufacture anti-reflective LCDs. HP Compaq procures and installs both anti-reflective and traditional LCD screens in their HP Compaq line of laptop computers. Those HP Compaq laptop models incorporating anti-reflective technology are marketed under the HP Compaq BrightView product name.
In addition, the high-gloss, anti-reflective technology marketed as HP Compaq BrightView is identical to the anti-reflective technology being marketed as Sony XBRITETM, X-black and Clear Bright; Toshiba TruBrightTM and Clear SuperView as well as product names marketed by other laptop brands.
The Technical Stuff
(Click here for a more detailed explanation including diagrams)
All LCD screens have a polarizer which is a thin sheet of film laminated to the outside layer of glass of the LCD screen used to filter light waves produced by the LCD screen to create a visual image. The difference between a traditional notebook screen also known as anti-glare and an anti-reflective notebook screen is the type of polarizer film.
The polarizer of a traditional anti-glare notebook screen has a rough matte finish. This matte finish causes ambient light to disperse or reflect off of the polarizer at different angles which reduces the intensity of the light reflected directly back to the observer’s eye. The side effect of the matte finish is blurred images, a lower contrast ratio, inferior viewing angles and eye fatigue to name a few.
The polarizer of an anti-reflective HP Compaq BrightView screen has a smooth finish which has been chemically-treated. The chemically-treated finish of the polarizer reduces ambient light reflection by absorbing much of the external light instead of dispersing it at different angles. Since the external light is mostly absorbed instead of being reflected at different angles, the polarizer does not need a rough matte finish and therefore a smooth finish can provide crisp, brilliant-colored images with the most direct light from the LCD.
In general, the observer sees light from two light sources: 1) light produced by the LCD specifically and 2) external ambient light which is reflected off the surface of the LCD. The aim of an anti-reflective polarizer is to decrease the intensity of reflected ambient light without sacrificing the quality of LCD imaging.

A u stvarnosti? Razliku nisam vidio. Niti bi mi bilo presudno uzeti laptop sa tom tehnologijom.
