Vibration sensing and canceling electronics
First Claim
1. An electronic device comprising:
- a display having a plurality of pixels;
an accelerometer with at least two orthogonal axes to generate voltage to indicate a direction and magnitude in response to a particular movement of the display;
a gain controller to tune a gain adjustment; and
a controller in communication with the accelerometer and the display, the controller to;
receive the voltage from the accelerometer;
in response to receipt of the voltage, reassign pixel values to cause a shift in content on the display in a direction opposite of the particular movement measured by the accelerometer such that the shift in content compensates at least in part for the particular movement measured by the accelerometer; and
selectively implement movement compensation based at least in part on the gain adjustment.

Abstract
This disclosure is directed at least in part to sensing movement of an electronic display and canceling perceived movement of content on the electronic display in response to the sensing. A controller may reassign “physical pixels” to “image pixels” (or virtual pixels) such that the image appears to be stationary while the physical pixels are moving due to movement of the electronic display. For example, if the physical pixels are moving upward, the image pixels may be reassigned downward in an equal and opposite manner. The user'"'"'s persistence of vision may then be reinforced by reassignment of the pixels by the display manager. For example, text displayed on the electronic display may be more readable and images more easily viewed by a user.

5. An electronic device comprising:
-
a display having a plurality of pixels that, when activated or deactivated, change a visual state; one or more sensors to generate signals based at least in part on a particular movement of the display; a gain controller to tune a gain adjustment; and a controller in communication with the gain controller, the one or more sensors and the display, the controller to; receive the signals from the one or more sensors; and selectively reassign pixel addresses to compensate at least in part for the particular movement of the display by changing the visual state of individual pixels of the plurality of pixels to shift content on the display in a direction opposite of the particular movement measured by the one or more sensors in response to receipt of the signals; and selectively implement movement compensation based at least in part on the gain adjustment. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)

15. An apparatus comprising:
-
a display having a plurality of pixels; one or more sensors to measure a particular movement of the display; a gain controller to tune a gain adjustment; and a controller in communication with the display and the one or more sensors, the controller to; receive signals from the one or more sensors; compensate at least in part for the particular movement of the display by reassigning pixel addresses to cause content on the display to move in a direction opposite of the particular movement of the display measured by the one or more sensors, wherein the compensation is based at least in part on the received signals; and implement movement compensation based at least in part on the gain adjustment. - View Dependent Claims (16, 17, 18, 19)
