Abstract
This disclosure relates to the use of variable-pitch light-emitting devices for display applications, including for displays in augmented reality, virtual reality, and mixed reality environments. In particular, it relates to small (e.g., micron-size) light emitting devices (e.g., micro-LEDs) of variable pitch to provide the advantages, e.g., of compactness, manufacturability, color rendition, as well as computational and power savings. Systems and methods for emitting multiple lights by multiple panels where a pitch of one panel is different than pitch(es) of other panels are disclosed. Each panel may comprise a respective array of light emitters. The multiple lights may be combined by a combiner.
Claims16
A system comprising:
- a first panel comprising a first array of light emitters, the first panel configured for emitting a first light at a first pitch, the first light comprising a first color;
- a second panel comprising a second array of light emitters, the second panel configured for emitting a second light at a second pitch, the second light comprising a second color, the second color different than the first color;
- a third panel comprising a third array of light emitters, the third panel configured for emitting a third light at a third pitch, the third light comprising a third color, the third color different than the first color and the second color;
- a combiner configured for receiving the first light, the second light, and the third light;
- and
- electronic circuitry configured for:
- receiving video data,
- performing color-wise down-sampling on the received video data to produce first down-sampled video data, the first down-sampled video data associated with the first color,
- performing color-wise down-sampling on the received video data to produce second down-sampled video data, the second down-sampled video data associated with the third color, and
- driving the first panel, the second panel, and the third panel, wherein:
- the first light emitted by the first panel is based on the first down-sampled video data, and
- the third light emitted by the third panel is based on the second down-sampled video data,
- wherein the second pitch of the second panel is smaller than the first pitch of the first panel and is smaller than the third pitch of the third panel.
A method comprising:
- emitting, by a first panel comprising a first array of light emitters, a first light at a first pitch, the first light comprising a first color;
- emitting, by a second panel comprising a second array of light emitters, a second light at a second pitch, the second light comprising a second color, the second color different than the first color;
- emitting, by a third panel comprising a third array of light emitters, a third light at a third pitch, the third light comprising a third color, the third color different than the first color and the second color;
- receiving, by a combiner, the first light, the second light, and the third light;
- receiving, at electronic circuitry, video data;
- performing, at the electronic circuitry, color-wise down-sampling on the received video data to produce first down-sampled video data, the first down-sampled video data associated with the first color;
- performing, at the electronic circuitry, color-wise down-sampling on the received video data to produce second down-sampled video data, the second down-sampled video data associated with the third color;
- and
- driving the first panel, the second panel, and the third panel, wherein:
- the first light emitted by the first panel is based on the first down-sampled video data, and
- the third light emitted by the third panel is based on the second down-sampled video data,
- wherein the second pitch of the second panel is smaller than the first pitch of the first panel and is smaller than the third pitch of the third panel.
