Abstract:
An example of an apparatus is provided. The apparatus includes a display portion and a camera. In addition, the apparatus includes a thin film transistor substrate extending over the display portion and the camera. Furthermore, the apparatus includes an image generation layer disposed under the thin film transistor substrate within the display portion. Also, the apparatus includes a polymer dispersed liquid crystal disposed between the thin film transistor substrate and the camera. The polymer dispersed liquid crystal is to be switched between an opaque state and a clear state. The opaque state is to block the camera from receiving imaging light. The clear state allows light to pass through the polymer dispersed liquid crystal.
