First Claim
1. A method of detecting hovering commands by a device with an active matrix organic light emitting diode (AMOLED) display, comprising:
- detecting a sequence of shadows from a hovering object by one or more light sensors of the AMOLED display, wherein the sequence of shadows causes changes in light conditions on the AMOLED display, wherein the changes in light condition are caused by shadows of the object formed, by ambient light in the background and by emitted light of the AMOLED display;
determining a leakage current corresponding to changes of light conditions by a controller of the device, wherein the leakage current decreases as the object approaches the AMOLED display, wherein the AMOLED display includes a plurality of pixel circuits, each pixel circuit includes a blue subpixel circuit, a green subpixel circuit, and a red subpixel circuit; and
wherein the green subpixel circuit and the red subpixel circuit are configured to sense the changes of light conditions, the blue subpixel circuit is configured to generate the emitted light of the AMOLED display in response to an ambient light in an environment of the device being less than a predetermined amount;
detecting, by the green subpixel circuit and the red subpixel circuit in each pixel circuit in the plurality of pixel circuits, the ambient light in an environment of the device being less than the predetermined amount;
emitting, by the blue subpixel circuit in each pixel circuit in the plurality of pixel circuits, a light to the hovering object from the AMOLED display of the device; and
receiving, by the green subpixel circuit and the red subpixel circuit in each pixel circuit in the plurality of pixel circuits, a reflected light from the hovering object, wherein the reflected light causes the changes in light conditions on the AMOLED display;
determining an action performed by a user based on the changes of light conditions on the AMOLED display by the controller of the device;
determining a hovering command based on the action performed by the controller of the device; and
executing the hovering command by the controller of the device.
