Abstract
The invention relates to a display device comprising a first light for emitting light rays and a first modulator operable to modulate those light rays for generating primary modulated light ray (10). A second light-source having a second modulator operable to generate secondary modulated light rays is also provided (14). The second light-source is transparent and is disposed relative to the first light-source such that primary modulated light rays generated by the first light-source are transmittable though the second light-source whereby a composite light-output comprising both primary and secondary modulated light rays is generated.
Claims27
A high dynamic range display device comprising:
- a first light-source having a first modulator to generate primary modulated light rays;
- a second light-source having a second modulator operable independently of the first light-source and the first modulator to generate secondary modulated light rays;
- and
- one or more optical components disposed between the first light-source and the first modulator and the second light-source and the second modulator for focusing the primary modulated light rays onto the second light-source and the second modulator,
- the second light-source and the second modulator being transparent and being disposed relative to the first light-source such that the primary modulated light rays generated by the first light-source are focused on and are transmittable through the second light-source and the second modulator whereby a composite light-output comprising both primary and secondary modulated light rays is generated, the composite light-output having a greater luminance dynamic range than either the primary modulated light rays or the secondary modulated light rays.
