Abstract
Display systems are described including augmented 1-dimensional pixel arrays and scanning mirrors. In one example, a pixel array includes first and second columns of pixels, relay optics configured to receive incident light and to output the incident light to a viewer, and a scanning mirror disposed to receive the light from the first and second columns of pixels and to reflect the received light toward the relay optics. The scanning mirror may move between a plurality of positions while the first and second columns emit light in temporally spaced pulses so as to form a perceived image at the relay optics having a higher resolution relative to the pixel pitch of the individual columns. Foveated rendering may provide for more efficient use of power and processing resources.
Claims19
A display system comprising:
- an emissive pixel array comprising first and second columns of pixels;
- relay optics configured to receive incident light and to output the incident light to a viewer;
- and
- a scanning mirror disposed to receive the light from the first and second columns of pixels and to reflect the received light toward the relay optics,
- wherein the scanning mirror is configured to move between a plurality of positions comprising a first position and a second position, the first position oriented for the scanning mirror to reflect the light from the first column of pixels onto the relay optics as a first one-dimensional array of pixels, the second position oriented for the scanning mirror to reflect the received light from the second column of pixels onto the relay optics as a second one-dimensional array of pixels,
- wherein locations for the first and the second one-dimensional array of pixels define spatially overlapping lines on the relay optics, and
- wherein the pixels of the first column of pixels are configured to emit light while the scanning mirror moves from a first position to a second position, and wherein the pixels of the second column of pixels are configured to emit light while the scanning mirror moves from the second position to the first position.
An optical apparatus comprising:
- a pixel array comprising:
- a first column of pixels having a first pixel pitch along a lengthwise dimension of the first column;
- and
- a second column of pixels having the first pixel pitch along a lengthwise dimension of the second column,
- wherein the lengthwise dimension of the first column extends along the lengthwise dimension of the second column, and wherein the pixels of the second column are offset along the lengthwise dimension relative to the pixels of the first column, and
- wherein the pixels of the first column of pixels are configured to emit light while a scanning mirror moves from a first position to a second position, and wherein the pixels of the second column of pixels are configured to emit light while the scanning mirror moves from the second position to the first position.
