  • Patent number: 8451244
    Abstract: 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.

  • Publication number: 20130076720
    Abstract: 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.

  • Patent number: 6580572
    Abstract: 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.

  • Patent number: 6519114
    Abstract: A storage medium is provided that includes a texture zone having a plurality of protrusions. Each of the protrusions is separated by a short circumferential pitch. Alternatively, the texture zone includes a plurality of protrusions with a circumferential pitch less than the diameter of any protrusion. The resonance excitation between the magnetic head and the storage medium in the data storage system is reduced by forming the texture zone with the protrusions that cause the excitation frequencies of the data storage system to shift away from its resonance frequencies.

  • Publication number: 20010050091
    Abstract: Cleaning a media surface, such as a disc surface, comprises subjecting the surface to a detector for sensing the nature of the surface for an irregularity in the smoothness of the surface. Directing, on detecting an irregularity beyond a predetermined amount, a burnishing pulse laser output to that irregularity, and energizing the laser to thereby impart an energy source to reduce the irregularity to a degree less than a predetermined amount.

  • Patent number: 6293135
    Abstract: 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.

  • Patent number: 6021666
    Abstract: A method of determining the close point for a glide head includes measuring the fly height of at least three positions remove from the selected close point position. The three selected positions are curve-fitted and extrapolated so as to obtain the height at the selected close point. Adaptions are made where the glide head can roll and measurements can be taken at locations transversely across the head.

  • Patent number: 6003364
    Abstract: An improved glide head is useful for testing the glide quality of a disc. The glide head includes an air bearing surface, pads extending from the air bearing surface and a contact sensor, the contact sensor providing an output in response to an impact on the pad. The air-bearing surface defines a resting plane. The pad protrudes from the air-bearing surface such that the pad projects below the resting plane of the air-bearing surface.
