A mobile terminal includes an optical modulation projector. The mobile terminal also includes a control system, a projection control unit, and an optical modulation system. The control system outputs a projection control signal and image data. The projection control unit receives the image data from the control system, and generates and outputs a drive control signal depending on the image data received. The optical modulation system generates and modulates light and generates an image in response to the drive control signal and then scans the image for projecting onto a screen.

Optical modulators including incorporated into mobile terminal projector

Disclosed herein is an apparatus for adjusting applied voltage in a display system using a diffractive optical modulator. The apparatus for adjusting applied voltage can measure the intensity of diffracted light emitted from the diffractive optical modulator, and adjust voltage to be applied to the diffractive optical modulator based on measurement results.
