ABSTRACT:
An image projection mechanism of a mobile phone has a light source section for image projection, a light modulator and a projection lens. The light source section has an LED device including an LED element having a luminous wavelength in a red color region, an LED element having a luminous wavelength in a green color region, and an LED element having a luminous wavelength in a blue color region, which are provided in one package, and a lens that converts light emitted from the LED device into substantially parallel rays. The three LED elements of the LED device are turned on and off sequentially, and the light modulator is operated synchronously with the sequential turning on-off of the LED elements, thereby projecting an image displayed on the light modulator as a multicolor image through the projection lens.
