DYNAMIC ADJUSTMENT OF TOUCH RESOLUTIONS ON AN AMOLED DISPLAY
First Claim
1. A method of dynamically adjusting a touch resolution of a video display having a plurality of pixel circuits each including a light emitting device driven by a driving transistor according to a programming current or voltage representing a desired brightness produced by the light emitting device, comprising:
- defining, by a controller, a first touch resolution of the video display to create a first plurality of capacitive touch zones relative to a transparent substrate of the video display as images are being displayed on the video display;
detecting a first touch on the transparent substrate in one of the first touch zones by measuring a voltage across an anode and a cathode of each of a first set of light emitting devices of the video display in the first touch zone;
dynamically changing, by the controller, the first touch resolution to a second touch resolution different from the first touch resolution to create a second plurality of capacitive touch zones relative to the video display as further images are being displayed on the video display; and
detecting a second touch in one of the second touch zones by measuring a voltage across an anode and a cathode of each of a second set of light emitting devices of the video display in the second touch zone.

Abstract
Dynamically adjusting a touch resolution of a display having pixel circuits each including an OLED driven by a driving transistor according to programming information representing a desired brightness for each OLED. A first touch resolution of the display is defined to create first touch zones relative to the display as images are being displayed thereon. A first touch in one of the first touch zones is detected by measuring a voltage across an anode and a cathode of each of a first set of OLEDs in the first touch zone. The first touch resolution is dynamically changed to a different second touch resolution to create second touch zones as further images are being displayed. A second touch in one of the second touch zones is detected by measuring a voltage across an anode and a cathode of each of a second set of OLEDs in the second touch zone.
