Electromagnetic rays radiating device for use in display device, has radiation uncoupling surface arranged in ray path of radiation-emitting arrangement, and radiation-steering unit directing electromagnetic ray to uncoupling surface

摘要

The device (100) has radiation-emitting arrangements (1, 2) respectively including radiation-emitting units (10, 20) for radiating respective electromagnetic rays (13, 23). A radiation uncoupling surface (5) is arranged in a ray path of the radiation-emitting arrangement (2), and a radiation-steering unit (3) directs the electromagnetic ray (13) to the radiation uncoupling surface. The electromagnetic ray (13) is controlled by the radiation-steering unit (3) toward the ray path of the electromagnetic ray (23). The arrangement (1) is arranged laterally offset to the uncoupling surface. An independent claim is also included for a display device comprising a liquid crystal matrix.
