Abstract: A method and apparatus are provided for detecting activation of a touch panel (16). The method includes the steps of providing an N by M touch panel (16) including a matrix of N rows of touch elements (22, 26) along a first axis and M columns of touch elements (22, 28) along a second axis, providing N optical beams (60, 62) where a characteristic of each beam of the N beams is different than the corresponding characteristic of any other of the N optical beams, where the summation of a characteristic any first group of the N optical beams (60, 62) is different than the summation the corresponding characteristic of any other N beams (60, 62) and where each respective beam of the N optical beams corresponds to an input of each of the N rows; and summing the characteristic from an output of each of the N rows. The method further includes the steps of providing M optical beams (60, 62) where a characteristic of each beam of the M beam (60, 62) is different than the corresponding characteristic of any other of the M optical beams, where the summation of a characteristic of any first group of the M optical beams is different than the summation the corresponding characteristic of any other M beams and where each respective beam of the M optical beams corresponds to an input of each of the M columns, summing the characteristic from an output of each of the M columns and unambiguously identifying a touch element or multi-touch elements (22, 26, 28) of the N rows and M columns of touch elements based upon the summation of the outputs.

Abstract: An multi-touch detection system (100) separately determines each of the coordinates of multiple touches and is able to correctly pair the coordinates, the touch panel includes multiple (e.g., two or four) separate sections (104, 106, 404, 406, 504, 506, 508, 510) to detect touches in different areas. The system (100) is able to operate at high refresh rates allowing speed sensitive applications to be supported.

Abstract: A user interface (200) for a portable electronic device (100) is configured to transition from a first state to a second state to present a plurality of mode-based user actuation targets to a user. The user interface (200) includes a segmented electro-optical device (407) configured to open and close shutters, thereby revealing and hiding the user actuation targets. The user interface includes a first polarizer (401) disposed above the segmented electro-optical device (407) and a colored reflective polarizer (405) disposed beneath the segmented electro-optical device. The colored reflective polarizer (405), which may include a colored dichroic polarizer (601) and a reflective polarizer (602), causes the user interface (200) to exhibit a predetermined color.

Abstract: In accordance with one embodiment, apparatus are provided, which include a burn-in compensation pixel generator and burn-in compensation circuitry. The burn-in compensation pixel generator is configured to generate burn-in compensation pixel data. The burn-in compensation circuitry is configured to provide, within break-from-standard-use periods of a device employing a display, the generated burn-in compensation pixel data instead of a select predetermined subset of default pixel data, for input to a display interface of the display.
