Modern high-resolution displays require anti-glare treatments that minimize sparkle (visual noise). This study achieved anti-glare properties with low sparkle by spray coating of silica sols. The silica sols contained polymerized species, synthesized by hydrolyzing a silicon alkoxide precursor. The size of the polymerized species was controlled by varying the amount of solvent added before aging the sols; the solutions were diluted further after aging so that their final apparent compositions were the same. The sizes of the polymerized species were measured with dynamic light scattering — the maximum Z-average value was 7.8 nm and the maximum volume-average value was 4.3 nm. Larger polymerized species made the lateral pitch of the anti-glare surface shorter, which explains the lower sparkle. Moreover, increasing the size of polymerized species is an effective way to increase the haze. This study shows for the first time that the anti-glare performance can be enhanced by increasing the size of polymerized species.

现代高分辨率显示器需要防眩光处理，以最大限度地减少闪光（视觉噪音）。该研究通过喷涂二氧化硅溶胶实现了低闪光的防眩光性能。硅溶胶含有聚合物质，通过水解硅醇盐前体合成。聚合物质的大小通过改变溶胶老化前添加的溶剂量来控制；溶液在老化后进一步稀释，使它们的最终表观组成相同。聚合物质的大小通过动态光散射测量——最大 Z 平均值为 7.8 nm，最大体积平均值为 4.3 nm。较大的聚合物质使防眩光表面的横向间距更短，这解释了较低的闪光。而且，增加聚合物种的尺寸是增加雾度的有效方法。该研究首次表明，通过增加聚合物种的尺寸可以提高防眩光性能。
