Abstract
Electronic devices, displays, and methods are provided for performing row shuffling to reduce an appearance of image artifacts during eye movements such as saccades. An electronic display may include a number of rows of display pixels and driving circuitry to drive the rows of pixels. The driving circuitry may spatially shuffle or temporally shuffle, or both spatially and temporally shuffle, a row order of driving the rows of display pixels.
Claims24
An electronic display comprising:
- a plurality of rows of light emitting diode display pixels comprising a first set of rows of display pixels and a second set of rows of display pixels;
- and
- driving circuitry configured to spatially shuffle or temporally shuffle, or both spatially shuffle and temporally shuffle, a row order of driving the plurality of rows of display pixels by:
- driving the first set of rows of display pixels based on a first monotonically from a top row to a bottom row of the first set of rows of display pixels increasing order;
- and
- driving the second set of rows of display pixels based on a second monotonically from a bottom row to a top row of the second set of rows of display pixels decreasing order.
One or more tangible, non-transitory, machine-readable media comprising instructions that, when executed by one or more processors, cause the one or more processors to cause operations comprising:
- spatially shuffling an order of driving a plurality of rows of light emitting diode display pixels of an electronic display by:
- causing at least some display pixels of a first set of the rows of display pixels to be driven in a first monotonically from a top row to a bottom row of the first set of rows of display pixels increasing order;
- and
- causing at least some display pixels of a second set of the rows of display pixels to be driven in a second monotonically from a bottom row to a top row of the second set of rows of display pixels decreasing order;
- or
- temporally shuffling an order of driving a plurality of rows of light emitting diode display pixels of an electronic display by:
- causing at least some display pixels of a first set of the rows of display pixels to be driven in a first monotonically increasing order from a top row to a bottom row of the first set of rows of display pixels during a first frame or subframe;
- and
- causing the at least some display pixels of the first set of the rows of display pixels to be driven in a second monotonically decreasing order from the bottom row to the top row of the first set of rows of display pixels during a second frame or subframe.
An electronic display comprising:
- a plurality of local passive matrices arranged in rows and columns, wherein each local passive matrix comprises a plurality of rows of light emitting diode display pixels;
- a plurality of micro-light emitting diode (LED) drivers configured to drive respective local passive matrices of the plurality of local passive matrices one row at a time based on a first monotonically from a top row to a bottom row of the plurality of rows of display pixels of the local passive matrix increasing order and a second monotonically from the bottom row to the top row of the plurality of rows of display pixels of the local passive matrix decreasing order, wherein a micro-LED driver of the plurality of micro-light emitting diode (LED) drivers comprises row selection circuitry to programmably select which row to drive.
An electronic device comprising:
- processing circuitry configured to produce configuration data for display on an electronic display, wherein the configuration data specifies a first monotonically increasing order from a top row to a bottom row of a first set of rows of light emitting diode display pixels to be illuminated and pixel data for the display pixels of the first set of rows and a second monotonically decreasing order from a bottom row to a top row of a second set of rows of light emitting diode display pixels to be illuminated and pixel data for the display pixels of the second set of rows, wherein the first order is different from the second order;
- and
- the electronic display comprising a plurality of micro-light emitting diode (LED) drivers configured to receive the pixel data, select the row specified by the configuration data, and drive the display pixels of the row using the pixel data of the configuration data.
A method comprising:
- driving rows of light emitting diode display pixels of a first local passive matrix of an electronic display in a first monotonically from a top row to a bottom row of the first local passive matrix increasing order during a first frame or subframe;
- and
- driving the rows of display pixels of the first local passive matrix in a second monotonically from the bottom row to the top row of the first local passive matrix decreasing order during a second frame or subframe or driving rows of a second local passive matrix of the electronic display in the second monotonically decreasing order from a bottom row to a top row of the second local passive matrix during the first frame or subframe, wherein the second order is different from the first order.
