What is the difference between anti glare and anti reflective display?

Anti-glare and anti-reflective displays are both designed to improve screen visibility, especially in bright lighting conditions, but they work in slightly different ways:

Anti-glare (AG) displays:

1. Have a matte finish on the screen surface
2. Diffuse incoming light, scattering it in multiple directions
3. Reduce visible reflections but may slightly blur the image
4. Are generally less expensive

5. Work well in environments with direct light sources

Anti-reflective (AR) displays:

1. Use thin film coatings on the screen surface
2. Reduce reflections by causing light waves to interfere with each other
3. Maintain image clarity and sharpness
4. Are typically more expensive
5. Perform better in a wider range of lighting conditions

In general, anti-reflective displays offer better overall image quality and clarity, while anti-glare displays are more effective at reducing harsh reflections from direct light sources. The choice between the two often depends on the specific use case and environment where the display will be used.
