摘要： Liquid crystal display (LCD) touch screens integrate touch sensing elements with display circuitry and may include in-plane-switching (IPS) LCDs. A method of operating the integrated touch sensing elements with the display circuitry includes dividing touch-sensing circuitry of the touch screen into a plurality of drive segments, each drive segment overlapping one or more display rows; updating the display at a predetermined refresh rate; stimulating the plurality of drive segments at a predetermined scan rate; and changing the sequence of stimulating the plurality of drive segments as required to prevent simultaneously stimulating a drive segment that overlaps a display row currently being updated.

摘要： Electrode configurations for reducing wobble error for a stylus translating on a surface over and between electrodes of a touch sensor panel are disclosed. In some examples, electrodes associated with a more linear signal profile are correlated with lower wobble error. In some examples, electrodes can have projections which can interleave with projections of adjacent electrodes. In some configurations, projections of adjacent electrodes can be interleaved in one-dimension; in other configurations, projections of adjacent electrodes can be interleaved in two-dimensions. In some configurations, the width and length of one or more projections in an electrode can be selected based on a desired signal profile for that electrode.

摘要： Disclosed herein are liquid-crystal display (LCD) touch screens that integrate the touch sensing elements with the display circuitry. The integration may take a variety of forms. Touch sensing elements can be completely implemented within the LCD stackup but outside the not between the color filter plate and the array plate. Alternatively, some touch sensing elements can be between the color filter and array plates with other touch sensing elements not between the plates. In another alternative, all touch sensing elements can be between the color filter and array plates. The latter alternative can include both conventional and in-plane-switching (IPS) LCDs. In some forms, one or more display structures can also have a touch sensing function. Techniques for manufacturing and operating such displays, as well as various devices embodying such displays are also disclosed.

摘要： A self-capacitive touch sensor panel configured to have a portion of both the touch and display functionality integrated into a common layer is provided. The touch sensor panel includes a layer with circuit elements that can switchably operate as both touch circuitry and display circuitry such that during a touch mode of the device the circuit elements operate as touch circuitry and during a display mode of the device the circuit elements operate as display circuitry. The touch mode and display mode can be time multiplexed. By integrating the touch hardware and display hardware into common layers, savings in power, weight and thickness of the device can be realized.

摘要： A touch controller. The touch controller can include first sense circuitry configured to be coupled to a first electrode on a touch sensor panel, the first sense circuitry configured to sense a first self-capacitance associated with the first electrode, and a first mutual capacitance associated with the first electrode. In some examples, the first sense circuitry can be configured to sense the first self-capacitance and the first mutual capacitance simultaneously. In some examples, the touch controller can further include a first mixer and a second mixer coupled to the first sense circuitry, the first mixer configured to demodulate a first output from the first sense circuitry to extract information about the first self-capacitance from the first output, the second mixer configured to demodulate the first output from the first sense circuitry to extract information about the first mutual capacitance from the first output.
