DISPLAY DEVICE, AND PORTABLE APPARATUS HAVING PROJECTOR FUNCTION

摘要

Disclosed is a display device wherein generation of luminance unevenness of a projected image is suppressed, while reducing the speckle noise of a laser beam. The display device (100) is provided with a control unit (15), which controls to output a laser beam by continuously supplying a current to laser beam generating sections (12, 13, 14) during a period longer than a first period without a stop, and which also controls to stop the laser beam output at least one time during a second period wherein one image forming element (1, 2) is scanned.
