Patent ID: 7896499

Claim:
A mobile phone comprising: a light source section for image projection including a light-emitting diode device that has three different kinds of light-emitting diode elements provided in one package and having different luminous wavelengths from each other to be turned on and off sequentially; a light modulator that operates synchronously with the sequential turning on and off of the light-emitting diode elements to project a multicolor image; a projection lens; a lens that collects light emitted from the light-emitting diode device and directs the light toward the light modulator; a first housing member having a first surface, a second surface opposite to the first surface, and an end surface extending between the first surface and second surface, the first housing member having a main display panel on the first surface; and a second housing member having a first surface, a second surface opposite to the first surface, and an end surface extending between the first surface and second surface, the second housing member having an operation panel on the first surface, and the second housing member having the first housing member that is pivotally attached to the second housing member such that the end surface of the first housing member is adjacent to the end surface of the second housing member, and the first housing member is displaceable to be pivoted between a folded position where the first surface of the first housing member abuts against the first surface of the second housing member and an unfolded position where the first surface of the first housing member is separate from the first surface of the second housing member, wherein the light source section is attached to the end surface of the second housing member to emit light in a direction away from the second housing member and in a direction substantially parallel to the first surface and second surface of the second housing member, and wherein the light modulator and the projection lens are attached to the first housing member and configured to be erectable on the second surface of the first housing member when the first housing member is placed in the unfolded position so that a light-receiving surface of the light modulator is substantially perpendicular to an optical axis of light from the light source section and an optical axis of the projection lens is substantially on a same line as the optical axis of light from the light source section.
