| 20100251817 | THERMAL MECHANICAL ISOLATOR FOR VACUUM PACKAGING OF A DISC RESONATOR GYROSCOPE - A single layer micromachined thermal and mechanical isolator may be bonded between a microelectromechanical system (MEMS) die and package. Small bond pads of the isolator are attached to the periphery of the die. The isolator material may be chosen to match that of the die, reducing CTE mismatch.

Thus, excessive stress or distortion to the package, from either CTE mismatch or external stress, may be absorbed by the isolator and will not be transmitted to the MEMS die. Beam rigidity may be designed to attenuate vibration of particular frequency range. The isolator can be readily inserted into an existing disc resonator gyroscope package in one thermal compression bond step. | 10-07-2010 |

In one embodiment, the LCD is a transflective display, and in another embodiment, the LCD is a pure transmissive display that relies on backlight for displaying images. | 05-12-2011 |

| 20110285640 | ELECTRIC FIELD SHIELDING FOR IN-CELL TOUCH TYPE THIN-FILM-TRANSISTOR LIQUID CRYSTAL DISPLAYS - Displays such as liquid crystal displays may be used in electronic devices. During operation of a display, electrostatic charges on the surface of the display may give rise to electric fields. One or more electric field shielding layers may be provided in the display to prevent the electric fields from disrupting operation of the liquid crystals material in the display. The shielding layers may be formed at a location in the stack of layers that make up the display that is above the liquid crystal material of the display. Touch sensors and thin film transistors may be located below the shielding layer. | 11-24-2011 |

| 20120113154 | COLUMN INVERSION TECHNIQUES FOR IMPROVED TRANSMITTANCE - Present techniques involve methods and systems of inversion patterns for pixels in a display. Inversion techniques involve driving image signals having a first polarity to data lines of a pixel matrix during a first time period and driving image signals having an opposite polarity to the data lines during a second time period. In some embodiments, the pixels may be configured to have electrodes having only two finger electrodes, thus widening the distance between electrodes and decreasing the susceptibility for crosstalk between pixels. In some embodiments, horizontal cross-talk of electromagnetic fields between pixels may be further reduced by configuring the data line driving scheme such that voltage polarity is flipped for the pixels along every two, three, or more data line columns. Furthermore, a Z inversion pattern may be employed to reduce the occurrence of undesirable display artifacts. | 05-10-2012 |
| 20120113357 | Transmissive Liquid Crystal Display with Reflective Mode - Method, system and device for a transflective liquid crystal display with both transmissive and reflective functions is realized by using a transflective component into a transmissive LCD. The transflective component can be a transparent substrate with patterned reflectors on one surface and repetitive patterned lenses or prisms formed on the opposite surface facing the backlight unit. The transparent areas substantially allow the optical beams to pass through. The light from the backlight is refracted or focused by the optical structures onto the transparent areas or apertures of other surface, thus a substantial amount of backlight transmits to the LC for light modulation for different gray levels. For the incident ambient light incident on the transflective component, the majority is reflected back to the viewer by the reflectors on the transflective component, and the remainder transmits the transflective component to the backlight unit and be recycled to be used again. | 05-10-2012 |
