Abstract

Various configurations of a display apparatus to mitigate a visual defect is disclosed. Such a visual defect may include a sensor mark that indicates the presence of a sensing element disposed beneath a screen, for instance, shown as edges of a fingerprint sensor, which may be visible to a user and distractive to the user experience. Visual, mechanical, and material properties of one or more layers between the display and the sensing element may be selected to prevent formation of or reduce the visibility of the sensor mark. In some configurations, a low elastic modulus or a low light reflectance material may be used. In some cases, the material may include a black adhesive. In some configurations, a polymer-based or metal-based spacer having a specific thickness may be used. In some configurations, a polarizer layer may be included.
