The screens of portable computers are divided into Glare, or flossy and AntiGlare, or mat. The advantage of the flossy screen is better contrast, colours and sharpness, therefore this type of monitor is preferred by home users. The disadvantage of this screen is the glare which disturbs seeing the image in bright lighting.
AntiGlare, or mat screens to some extent prevent the glare problem by "scattering". This type of screen is usually used in business class computers intended for working with documents and accounting systems.
