A visual display panel has a viewing area formed on one face on a block of optical grade transparent material. The block face opposite the viewing area has a profiled set of controllable reflectors 16 and 17 formed in close proximity to the substrate. By suitable selection, the reflectors may be activated by electronic means to deflect a collimated or coherent light beam to display information. This light beam is managed by a electronic control system to show information in colour or monochrome. The reflectors each comprise a thin metal film deposited on a substrate. <IMAGE> |
