"Most LCD screens use an anti-glare (AG) treatment on their top surface to diffuse the reflected light from external lighting sources. This is also true of some older CRT monitors. This treatment consists of laminating a matte (rough) surface layer to the LCD. When light hits this rough surface it bounces off at different angles which reduces the intensity of light reflecting off of the surface and hitting your eyes. While this reduces the intensity of light, it does, however, leave a hazy image of the reflection which may block the onscreen image. Unfortunately, this treatment also distorts the image generated by the LCD."
This is what screentek said about matte finish screens, and it pretty much described the difference I saw btw my WXGA screen and the glossy screen on the HP my father in law has.
Here is what they desribe as advantages of a anti-reflective(glossy screen):
Anti-reflective LCD screens have many advantages over traditional anti-glare LCD screens which have historically been used in laptop computers. Advantages of anti-reflective LCD screens include:
- Sharper contrast
- Crisper images
- Colors that are richer
- Wider viewing angles
- No reflected hazy image
The advantages of anti-reflective LCD screens over anti-glare LCD screens are simply the result of using a smooth high-gloss surface. A high-gloss surface allows the light from an image to be directly transmitted to the viewer’s eye without being diffused. Diffused light blurs the crispness of an image, blurs the richness of colors and reduces the darkness of the darkest of black pixels thereby decreasing contrast. Contrast ratio (CR) is the measurement of the difference in light intensity between the brightest white pixel and the darkest black pixel.
