Anti-glare (AG) films are applied to displays to minimize reflections from ambient light and ensure that important information is viewable. However, displays that use these films and coatings are prone to a visual effect called sparkle, which causes low display clarity that can appear grainy to a human observer.
Measuring perceived sparkle ensures that the quality standard for AG displays is driven by the intended experience of the viewer. Such a measurement can be used not only in quality control during display production, but also in supplier qualification by OEMs who source third-party displays for integration. This paper describes precise geometric, optical, and software parameters of a sparkle measurement method, which has been proven to match human visual perception of display quality with repeatable results. Using this method, OEMs and manufacturers of displays can define precise, measurable tolerances for sparkle and establish standard quality control processes for anti-glare (AG) displays.
In this White Paper, you will learn about:
- Anti-glare (AG) layer properties and their effect on visual display quality
- Tools for isolating sparkle for accurate AG display measurement
- System and measurement parameters that enable repeatable quantification of sparkle percentage
- How data has been correlated with human perception of display quality
