Abstract: A method for unlocking a mobile device is disclosed. When the mobile device is in the lock mode, the touch panel screen on the mobile device detects a multi-touch action simultaneously performed by users. The users perform the multi-touch action on a plurality of the touch points displayed on the touch panel screen. If the multi-touch action satisfies a predetermined unlock condition of the mobile device, the mobile device switches from a lock mode to an unlock mode. The simultaneous multi-touch action is provided to users for unlocking the mobile device. Thus, the simultaneity of the action is utilized to shortening the operating time of the unlock process.

Voltage polarities of the first state and the second state are opposite. The pixel design can improve color shift and frame flicker.

Abstract: This disclosure primarily concerns 3D stereoscopic displays that provide alternately polarized left and right eye images encoded with a modulating LC polarization control panel (PCP) attached to the front of the display. Viewers then wear polarization analyzing eyewear to correctly see the different images. More specifically, the disclosure introduces global LC electrical reset during the addressing of liquid crystal time-sequential stereoscopic displays in order to reduce left/right eye contamination. LC materials in general do not respond fast enough with conventional addressing schemes to provide independent left and right eye images at the desired flicker-free, rate of sixty frames per second per eye. This disclosure and its embodiments may overcome this limitation, and also may address motion blur limitations, by driving pixels to a common LC state as part of the addressing cycle.
