Data can be written to a sub-pixel by applying a voltage to the sub-pixel's data line. 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 the appearance of these visual artifacts by inserting guard lines between data lines to reduce the mutual capacitance between data lines. In other embodiments, a pixel having multiple gate lines can be used to selectively turn on and turn off different sub-pixels which, in turn, can reduce or eliminate the appearance of visual artifacts.

A method and apparatus for calibrating a glide head and detector system performs a pre-screening to ensure the quality of the glide head and the piezoelectric sensor in the detection system. The glide head and the piezoelectric sensor detect a signal when the glide head makes contact with the disk, such as a magnetic recording disk. Calibration of the detection system utilizes a specially made bump disk that has asperities of desired height and size that protrude out of a flat disk surface. The glide head is flown over the bump disk, and by gradually reducing the disk spinning velocity, the head is brought closer to the disk and eventually into contact with the asperity. The onset of contact, as detected by the piezoelectric sensor, defines a disk spinning velocity for the head to fly at the desired height. In order to decouple the glide head flying characteristics and the piezoelectric quality and transfer function from other factors that affect the calibration of the detection system, laser pulses are directed at the glide head. Head vibrations are introduced in the glide head and detected by the piezoelectric sensor. The head excitations are recorded as a spectrogram in which the resonance frequencies are observed. From the amplitude and frequency readings, head resonance frequencies are identified and the piezoelectric sensor response is characterized. This allows the pre-screening of the head/sensor system and the decoupling of the glide head flying characteristics and the piezoelectric sensor quality from the asperity integrity effects on the calibration of the detection system.

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.

A combination glide test/burnishing head can be utilized in a glide test/burnishing system. The combination glide test/burnishing head includes two piezo-electric elements, which can be utilized in a passive mode as sensors for detecting contacts between the glide test/burnishing head and asperities on the surface of a magnetic recording disc. Contact between the glide test/burnishing head and disc asperities results in generation of a defect detection signal, which can be utilized by associated test logic to define the location of the detected asperities on the disc surface. The piezo-electric elements of the glide test/burnishing head can also be utilized in an active mode to cause yaw variation in the flight attitude of the glide test/burnishing head, in turn causing a burnishing pad on the glide test/burnishing head to be moved radially into contact with a detected disc asperity. Once an active, burnishing operation has been performed, the piezo-electric elements of the glide test/burnishing head are returned to passive mode, to determine if the burnishing operation was successful in removing the asperity on the disc surface. Combining the glide test and burnishing functions in a common head assembly allows the glide test and burnishing functions to be performed using a single actuator for the glide test/burnishing head, simplifying and reducing the cost of a glide test/burnishing system.
