Abstract: A rear-projection television set includes a television screen, an image projector, first and second imaging lens units, and first and second reflecting mirror sets. The television screen has an optical axis and first and second image rendering portions disposed on opposite sides of the optical axis. The image projector is disposed rearwardly of the television screen and is aligned with the optical axis. The first and second imaging lens units cooperate to separate the image output of the image projector into first and second image portions. Each of the first and second reflecting mirror sets receives a respective one of the first and second image portions from the first and second imaging lens units, and projects the respective one of the first and second image portions to a respective one of the first and second image rendering portions of the television screen.
