US Patent 10902787 Asynchronous control of display update and light emission

An apparatus for display includes an active region, a gate scanning driver, and light emitting driver. The active region includes a plurality of subpixels. The gate scanning driver is operatively coupled to the active region and configured to scan the plurality of subpixels in a first period of each frame at a first rate. The light emitting driver is operatively coupled to the active region and configured to cause the plurality of subpixels to start emitting light in a second period of each frame at a second rate. The second rate is higher than the first rate. The second period overlaps the first period.
