摘要： With respect to liquid crystal display inversion schemes, a large change in voltage on a data line can affect the voltages on adjacent data lines due to capacitive coupling between data lines. The resulting change in voltage on these adjacent data lines can give rise to visual artifacts in the data lines' corresponding sub-pixels. Various embodiments of the present disclosure serve to prevent or reduce these visual artifacts by applying voltage to a data line more than once during the write sequence. Doing so can allow erroneous brightening or darkening caused by large voltage swings to be overwritten without causing additional large voltage swings on the data line.

摘要： Negative pixel compensation to compensate for a negative pixel effect in touch signal outputs due to poor grounding of an object touching the device is disclosed. To do so, the device can switch to a configuration to measure the grounding condition of the touching object and use the measurement to compensate the touch output values. In the switched configuration, a first set of lines of the device can be switched between a coupling to a stimulation signal input to drive the device, a coupling to a capacitance signal output to output a signal indicative of the object's grounding condition, and a coupling to ground. A second set of lines of the device can be coupled to a touch signal output to output a signal indicative of the object's touch at the device. The grounding signal can be applied to the touch signal to compensate for the negative pixel effect.

摘要： A controller for a touch sensor includes a transimpedance amplifier, and a feedback resistor coupled to an input of the transimpedance amplifier and to an output of the transimpedance amplifier. At least one multiplexor may be coupled to the input of the transimpedance amplifier and configured to multiplex a plurality of analog inputs to one dedicated channel. The controller may further include a bandpass filter coupled to the output of the transimpedance amplifier. The output of the bandpass filter may be input to an anti-aliasing filter, which feeds into an analog to digital converter. Alternatively, the output of the bandpass filter may be input to a sigma-delta analog to digital converter.

摘要： A dual-axis rotational rate sensor having two vibratory masses coupled to a restoring element and driven in a resonant counter-phase motion, wherein the two masses vibrate with equal but opposite amplitudes along a single axis. The vibratory structure also accommodates motion of the masses in a plane orthogonal to the vibratory axis. Measurement of the motion of the masses in two axes in this plane provides signals directly responsive to rotation of the sensor about two orthogonal axes. Measurement and drive is facilitated by the use of magnetic masses and electromagnetic drive and sense transducers.

摘要： A light guide panel is disclosed. The panel comprises a plate for dispersing light and at least one light-emitting diode (LED) coupled to the plate for providing the dispersed light. When the panel is coupled to a keyboard, the at least one LED is under a portion of the keyboard such that when the at least one LED is illuminated, the light from the LED does not distract a user. Accordingly, by strategically placing LEDs within the panel and providing the LEDs under appropriate portions of the keyboard, the device utilizing the keyboard can be smaller than when a conventional light guide panel is utilized. In addition, a further improvement in illumination is provided when a mechanism is provided which reflects light escaping from the edges of the panel back into the panel.
