The transparent display has attracted attention from industrial and research fields due to its broad applications in many fields, including mobile displays, wearable devices, and head-up displays in automobiles. However, the visibility of images on transparent displays is degraded under bright ambient conditions and cluttered backgrounds. This paper analyzes visibility degradation under various backgrounds and ambient conditions. Then, a background- and ambient-aware visibility enhancement algorithm is proposed, where the transmittance rejection rate for degraded pixels is adjusted to enhance the visibility. The experimental results show that the proposed algorithm can enhance visibility under various backgrounds and ambient conditions, which promises the applicability of a transparent display in outdoor environments.
