Abstract: This disclosure provides systems, methods and apparatus for a touch screens configured to determine a position of a touch event by selectively redirecting light to correlated locations on a light sensor. In one aspect, the touch screen apparatus can include a light guide forming a touch interface, a light source for injecting light into the light guide, a light sensor for detecting the injected light, and a pixilated light-turning layer. The pixilated light-turning layer can include a plurality of light-turning features forming pixels. The pixels can receive incident light corresponding to the emitted light scattered by an object contacting the light guide. The pixels can redirect the incident scattered light towards the light sensor such that light selectively propagates to one or more correlated light receiving locations. A processor can map the light receiving location to an area contacted by the object, thereby determining a position of a touch event.

Abstract: A liquid crystal display device includes: a display control unit configured to cause the liquid crystal panel to display a right eye image and a left eye image in an alternating manner; and a polarity control unit configured to cause the polarity of the drive voltage for the liquid crystal panel to be reversed. The polarity control unit causes the polarity of the drive voltage to be reversed such that, in one cycle including a number of display frames for right and left eye images, the number being a multiple of 8, the combination of polarities for image display in one pair of display frames composed of right and left eye images is one of four combinations and a number of occurrences of each of the four combinations is equal.

Abstract: Negative pixel compensation in a touch sensor panel is disclosed. The panel can compensate for a negative pixel effect in touch signal outputs due to poor grounding of an object touching the panel. To do so, the panel can reconstruct a captured touch image to remove negative pixel values indicative of the negative pixel effect and compute a composite image from the captured image and the reconstructed image to replace the captured image. In addition or alternatively, the panel can reconstruct a captured touch image to remove negative pixel values indicative of the negative pixel effect and replace the captured image with the reconstructed image.

Abstract: Asymmetric scanning logic implements asymmetric panel scanning by scanning some rows on a touch panel more frequently than other rows. Note that although an entire row at a time may be driven, if only particular pixels in the row are of interest (e.g., included in any region of interest for focused asymmetric scanning), then circuitry may power down the receivers for the columns in which the pixels exist to save power. The asymmetric scanning logic facilitates focused attention to specific areas of interest on the touch panel, to compensate, for example, for high noise or low signal strength in those areas of interest.

The keyboard logic assigns a prediction value to each key based on a statistical probability that the key will be entered next.

Abstract: Devices and methods are disclosed which relate to improving the efficiency of text input by measuring the angle of each key press and rejecting improbable keys pressed at an off-center angle. Examples include a text-entry device which has logic for resisting error while the user enters text on a keyboard of the text-entry device. Each key determines the angle at which the key is pressed. Keyboard logic on the text-entry device assigns a range of acceptable angles to each key. If a key is pressed within the range of acceptable angles, which is typically around the center, then the entry is permitted. If a key is pressed outside the range of acceptable angles, which is typically on the edges, then the entry is denied. Once text is entered, the keyboard logic assigns a prediction value to each key based on a statistical probability that the key will be entered next. The keyboard logic then adjusts the range of acceptable angles based on that statistical probability.
