Abstract
A scanning type display device includes a light source that includes multiple rows and columns of light emitters. The display device also includes a rotatable mirror that projects light to different areas of an image field as the mirror rotates. There can be a redundant number to light emitters in the light source to increase the brightness of the pixels in the image field. A data driver may replicate and shift data values among light emitters of the same columns. The light emitters may operate in conjunction with the mirror in a synchronized manner. Owing to the shift in data value and the rotation of the mirror, the mirror may first project light from a first light emitter to a pixel and may then project light from a second light emitter with the same brightness level to the same pixel. The shifting may continue for additional light emitters.
