For a successful combination of film and book we use flat miniature TFT displays that can be integrated into the cover. The maximum length of the movies is 60 minutes. The power supply will be guaranteed by a rechargable lithium battery. You can activate the movie by pressing the On/Off button or by triggering the light light sensor or the a magnet. We always suggest to integrate to display on the backside of the cover. The film will automatically start when the book is opened. The perfect combination of the analogue and the digital.
