  • Patent number: 9201540
    Abstract: Techniques for operating a touchscreen display are disclosed herein. In one embodiment, the touchscreen display device includes power regulation circuitry that supplies a first set of voltages to a display panel using high and low supply rails during a display period. During the blanking period following the display period, the high and low supply rails may be adjusted to a second set of voltages that provide for proper operation of touch-sensitive elements in the touchscreen display. Following the end of the blanking period, a portion of charge from the low supply rail is recycled by transferring the charge from the low supply rail back to the high supply rail to bring the high and low supply rails back to the first set of voltages for the next display period.

  • Patent number: 9196207
    Abstract: Techniques for controlling the slew rate of a signal independently of RC time constants are disclosed. In one embodiment, a gate driver circuit for an LCD panel may include a rail-to-rail operational amplifier having an output stage configured to produce a gate activation signal for switching pixels of the LCD panel. A slew rate control circuit may be provided for adjusting the slew rate of the gate activation signal by varying a bias current of the output stage relative to a compensation capacitance and a gain of the operational amplifier. For instance, the slew rate may be increased by increasing the bias current, and decreased by decreasing the bias current without the need to adjust RC variables.
