7. A projector comprising:
-
a light source unit for emitting light; a projection lens for projecting images on a screen; and a liquid crystal panel comprising; a liquid crystal display element with a light input surface and a light output surface; a micro-lens array disposed on the light input surface; an adjustable lens array disposed on the light output surface; and a lens control unit electrically connected to the adjustable lenses for controlling focal length of the adjustable lens array; wherein the liquid crystal display element, the micro-lens array and the adjustable lens array are so arranged that the light from the light source unit is first converged onto the light input surface of the liquid crystal display element by the micro-lens array, and the light entering the liquid crystal display element is modulated by the liquid crystal display element according to given image data before emitted from the light output surface;
then the light emitted from the light output surface is modulated by the adjustable lenses array via the focal length of the adjustable lenses array controlled by lens control unit so that the light emits from the adjustable lens array with an adjustable angular difference before entering the projection lens. - View Dependent Claims (8, 9, 10)
