1Object-affected harmful factors
If a matte layer with a matte surface is used to reduce glare, then the anti-glare effect is improved, but the display brightness at large viewing angles is significantly reduced
Solution Approach 1:
The patent changes the geometric parameters of the microstructures by defining specific relationships between cross-sectional area, included angle, and height through mathematical formulas. This allows optimization of the microstructure geometry to achieve both anti-glare effect and maintain brightness at large viewing angles
Solution Approach 2:
The patent transitions from conventional 2D surface treatments to 3D microstructures with specific geometric configurations. By controlling the three-dimensional shape and distribution of microstructures, the patent achieves superior optical performance that balances anti-glare effects with maintained brightness

AI summary
An anti-glare layer and a display device are provided. The anti-glare layer includes a bottom surface and a microstructure surface opposite to each other. The microstructure surface has a plurality of microstructures disposed thereon. In the normal direction perpendicular to the bottom surface, a virtual reference plane parallel to the bottom surface passes through the points of the microstructures closest to the bottom surface, and k virtual sectional planes are sequentially defined along the normal direction from the virtual reference plane on the side opposite to the bottom surface. The virtual sectional planes are spaced apart from each other by a gap D. The cross-sectional area sum of the microstructures on the n-th virtual sectional plane, the mean included angle of the microstructures at intersection with the n-th virtual sectional plane, and the area of the bottom surface satisfy a certain relation to improve the brightness of large viewing angles as well as user experience, while taking account of an anti-glare effect.
