Definitions
- the present invention relates to the field of projection display, and more particularly to a projection display device.
- the liquid crystal display is widely used in daily production and life due to its large color gamut, wide viewing angle and thin structure, such as LCD TV display and liquid crystal projection display.
- home projectors have gradually entered the eyes of people, their small size, do not occupy the family space; easy to move, can be displayed in many places such as walls, ceilings; display effect is excellent, you can find a theater in a small home The effect of watching.
- a conventional liquid crystal projector generally realizes an image by combining light emitted from a light source to form a plurality of sub-optical paths of color light such as red, green, and blue, and separately controlling light of different colors, and combining light of different sub-paths. Projection, which can only display a single picture.
- Embodiments of the present invention provide a projection display device, including:
- a light source for emitting a light beam
- An optical path switching device for switching a light beam emitted from a light source between a first optical path and a second optical path
- the light modulating device is configured to modulate a light beam in the first optical path to generate a first for the first display position if the optical path switching device switches the light beam emitted by the light source to the first optical path The image is displayed, and the light beam in the second optical path is modulated to generate a second display image for the second display position in the case where the optical path switching device switches the light beam emitted from the light source to the second optical path.
- the first display image and the second display image are different images.
- the first modulation unit and the second modulation unit are both smaller than 0.032 mm in size.
- the first display position and the second display position are spaced apart from each other without overlapping.
- the light emphasizing portion is in a normally black mode, that is, no driving signal is applied.
- the light-improving portion 510 is driven, if the optical path switching device 40 switches the light beam 11 emitted from the light source 10 to the first optical path 20, the driving signals corresponding to the first display image can be respectively loaded to 4a and 4b are located in the first modulation unit 501 of the odd column to generate the first display image, and no second drive unit 502 is opaque to the second modulation unit 502; otherwise, if the optical path switching device 40, by switching the light beam 11 emitted by the light source 10 to the second optical path 30, the driving signals corresponding to the second display image can be respectively loaded into the second modulating unit 502 located in the even column in FIGS.
- light source 10 may include various light sources known in the art, such as mercury lamps, light emitting diodes, fluorescent lamps, and the like.
