A glossy display is an electronic display with a glossy surface. In certain light environments, glossy displays provide better color intensity and contrast ratios than

matte display A matte display is an electronic display with a matte surface. Matte displays feature a light-scattering antireflection layer, which reduces reflectivity at the cost of decreased contrast and color intensity under dimly lit conditions.Johnson, J ...

s. The primary disadvantage of these displays is their tendency to reflect any external light, often resulting in an undesirable glare.Thatcher, Michelle

Technology

Some LCDs use an antireflective coating, or nanotextured glass surface, to reduce the amount of external light reflecting from the surface without affecting light emanating from the screen as an alternative to

Disadvantages

Because of the reflective nature of the display, in most lighting conditions that include direct light sources facing the screen, glossy displays create reflections, which can be distracting to the user of the computer. This can be especially distracting to users working in an environment where the position of lights and windows are fixed, such as in an office, as these create unavoidable reflections on glossy displays.

Adverse health effects

Ergonomic studies show that prolonged work in the office environment with the presence of discomforting glares and disturbances from light reflections on the screen can cause mild to severe health effects, ranging from eye strain and headaches to photosensitive epileptic episodes. These effects are usually explained by the physiology of the human eye and the human visual system. The image of light sources reflected in the screen can cause the human visual system to focus on that image, which is usually at a much farther distance than the information shown on the screen. This competition between two images that can be focused is considered to be the primary source of such effects.

Advantages

In controlled environments, such as darkened rooms, or rooms where all light sources are diffused, glossy displays create more saturated colors, deeper blacks, brighter whites, and are sharper than
