Abstract

An interactive display unit for presenting information and for interacting with a user, in particular in a vehicle interior, includes at least one imaging cell including a photorefractive polymer material layer between two transparent substrate carriers in a sealing arrangement. Each substrate carrier includes a transparent electrode layer that faces the photorefractive polymer material layer. A writing light source with a propagation oriented in the direction of the photorefractive polymer material layer is arranged on one of the substrate carriers in a parallel manner with respect to the substrate carrier. A haptic sensor/actuator unit is arranged on the other substrate carrier, and at least one reading light source with a propagation oriented in the direction of the photorefractive polymer material layer is arranged in a lateral manner.
