摘要： Measuring an effect of body capacitance in a touch sensitive device is disclosed. This effect can be caused by poor grounding of a user or other objects touching the device or of the device itself. The device can operate in a stray capacitance mode to measure a body capacitance effect and in a normal mode to detect a touch on the device. During the stray capacitance mode, the device can obtain a body capacitance measurement from the device. During the normal mode, the device can obtain a touch measurement from the device. The device can calculate a body capacitance factor based on a ratio between the body capacitance measurement and the touch measurement and use the body capacitance factor to compensate for erroneous or distorted touch output values from the device. Various components of the device can be switchably configured according to the particular mode.

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： A touch sensing device having conductive nodes is disclosed. The device can include a first structure having one or more conductive electrodes disposed on a surface opposite the structure's touchable surface and a second structure having one or more conductive nodes disposed on a surface. The two surfaces can be placed with the conductive electrodes and conductive nodes facing each other in close proximity so that the electrodes and the nodes can form capacitive elements for sensing a touch on the touchable surface. Separately disposing the conductive nodes from the touchable surface structure can make the touch sensing device thin. An example touch sensing device can be a click wheel.

摘要： Negative pixel compensation in a touch sensitive device is disclosed. The device can compensate for a negative pixel effect in touch signal outputs due to poor grounding of an object touching the device. 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 from the device accordingly. 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. In addition or alternatively, in the switched configuration, the first set of lines of the device can be switched to function as the second set of lines and vice versa. The grounding signal can be applied to the touch signal to compensate for the negative pixel effect.

摘要： Displays with touch sensing circuitry integrated into the display pixel stackup are provided. An integrated touch screen can include multi-function circuit elements that can operate as circuitry of the display system to generate an image on the display, and can also form part of a touch sensing system that senses one or more touches on or near the display. The multi-function circuit elements can be, for example, capacitors in display pixels that can be configured to operate as storage capacitors/electrodes, common electrodes, conductive wires/pathways, etc., of the display circuitry in the display system, and that may also be configured to operate as circuit elements of the touch sensing circuitry.

摘要： Displaying an image on a display screen is provided by periodically changing the scanning order in which rows of sub-pixels of the display screen are scanned. One scanning order can be selected to scan the rows in the update of a first image frame of the display, and then a different scanning order can be selected to scan the rows in the update of a second image frame. Particular scanning orders can be selected in order to reduce or eliminate the appearance of visual artifacts by changing the location of the visual artifacts across multiple image frames. For example, different scanning orders that result in visual artifacts at different positions on the display screen can be used, and the selection of scanning order can periodically change among the different scanning orders such that the position of the visual artifacts changes periodically during the updating of multiple image frames.

摘要： A method of laminating a surface of a flexible material to a surface of a rigid, curved material. The method includes pressing an area of the surface of the flexible material into the surface of the rigid, curved material with a holder to create a contact area while the flexible material is conformed to the holder, which has a curvature greater than a curvature of the rigid, curved material surface; and changing the contact area between the surface of the flexible material and the surface of the rigid, curved material while maintaining pressure on the contact area until the surface of the flexible material and the surface of the rigid curved material are laminated.

摘要： A touch sensitive device having circuitry to compensate for crosstalk from the device display to the device touch sensor panel is disclosed. The crosstalk compensation circuitry can include a downsampler and a crosstalk compensator. The downsampler can downsample a display image to a manageable size for transmission and processing and can then send the downsampled image to the crosstalk compensator so as to provide information about the display operation that can be used to estimate the expected amount of crosstalk caused by the display. The crosstalk compensator can estimate the amount of crosstalk based on the downsampled image and can then compensate a touch image captured by the touch sensor panel for the estimated amount, the touch image being indicative of a touch or hover event at the panel.

摘要： Reduction of the effects of differences in parasitic capacitances in touch screens is provided. A touch screen can include multiple display pixels with stackups that each include a first element and a second element. For example, the first element can be a common electrode, and the second element can be a data line. The display pixels can include a first display pixel including a third element connected to the first element, and the third element can contribute to a first parasitic capacitance between the first and second elements of the first display pixel, for example, by overlapping with the second element. The touch screen can also include a second display pixel lacking the third element. The second display pixel can include a second parasitic capacitance between the first and second elements of the second display pixel. The first and second parasitic capacitances can be substantially equal, for example.
