Abstract: A stylus capable of bidirectionally communicating with a sensor controller includes a receiver that receives an uplink signal sent by the sensor controller, a controller that determines whether a signal having a predetermined waveform is to be continuously sent over a second time period or to be continuously sent over a first time period longer than the second time period, on the basis of the uplink signal, and a transmitter that continuously sends the signal having the predetermined waveform over the first time period or the second time period on the basis of the result of determination by the controller. As a result, the sensor controller can detect a burst signal from the stylus over a wide range in a sensor touch surface, to thereby reduce the possibility that the sensor controller may fail to detect the burst signal.

Abstract: An improved AM OLED pixel circuit and method of wide dynamic range dimming for AM OLED displays are disclosed that maintain color balance throughout the dimming range, and also maintain the uniformity of the luminance and chromaticity of the display at low gray-levels as the display is dimmed to lower luminance values. As such, AM OLED displays can meet the stringent color/dimming specifications required for existing and future avionics, cockpit, and hand-held military device display applications. Essentially, the OLED pixel circuit and method of dimming that are disclosed use Pulse Width Modulation (PWM) of the OLED pixel current to achieve the desired display luminance. Two example circuits are disclosed that externally PW modulate the common cathode voltage or common power supply voltage to modulate the OLED current in order to achieve the desired display luminance.

Abstract: The invention provides a method and apparatus for identifying gestures performed by a user to control an interactive display. The gestures are identified based on a bounding box enclosing the points at which a user contacts a touch sensor corresponding with the display surface. The invention thus permits the use of inexpensive and highly reliable grid-based touch sensors that provide a bounding box to describe contact information. In identifying the gestures, the position, motion, shape, and deformation of the bounding box may all be considered. In particular, the center, width, height, aspect ratio, length of the diagonal, and orientation of the diagonal of the bounding box may be determined. A stretch factor, defined as the maximum of the ratio of the height of the bounding box to the width of the bounding box and the ratio of the width of the bounding box to the height of the bounding box, may also be computed.

Abstract: An organic light-emitting diode display may have an array of pixels. Each pixel may have multiple subpixels of different colors. To avoid undesired color shifts when operating the display, the display may be configured so that subpixels of different colors are not coupled to each other through parasitic capacitances. The subpixels may include red, green, and blue subpixels or subpixels of other colors. Each subpixel may include an organic light-emitting diode having an anode and a cathode. The anode of each organic light-emitting diode may be coupled to a respective storage capacitor. Capacitive coupling between subpixels can be minimized by configuring the subpixel structures of each pixel so that the storage capacitors of the subpixels do not overlap the anodes of other subpixels in the pixel. Anode and capacitor overlap with subpixel data lines may also be reduced or eliminated.
