US 10,951,867 B2 · Light emitter architecture for scanning display device

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.

Dependent claims

A method comprising:

loading data values onto a data driver of a display device;
sending a data signal representing a data value to a first light emitter in a column;
operating the first light emitter according to the data signal in a first portion of a frame period;
shifting the data signal to a second light emitter in the same column as the first light emitter;
and
operating the second light emitter according to the shifted data signal in a second portion of the frame period, wherein light emitted from the first light emitter is projected to a pixel in the first portion of the frame period and light emitted from the second light emitter is projected to the same pixel in the second portion of the frame period.
