  • Patent number: 9104258
    Abstract: This relates to adding multi-touch functionality to a display without the need of a separate multi-touch panel or layer overlaying the display. Instead, embodiments of the invention can advantageously utilize existing display circuitry to provide multi-touch functionality while adding relatively little circuitry that is specific to the multi-touch functionality. Thus, by sharing circuitry for the display and the multi-touch functionalities, embodiments of the invention can be implemented at a lower cost than the alternative of superimposing additional multi-touch related layers onto an existing display panel. Furthermore, since the display and multi-touch functionality can be implemented on the same circuit, they can be synchronized so that noise resulting from the display functionality does not detrimentally affect the multi-touch functionality and vice versa.

  • Patent number: 9036212
    Abstract: A method is disclosed. The method includes generating a Continuous Tone Image (CTI) with all pixel values same as the first gray level and an initial Half Tone Image (HTI) with all pixel values equal to minimum absorptance level, computing a change in pixel error by toggling with all the possible output states and swapping with all neighbor pixels only if the stacking constraint is satisfied, updating the HTI with the maximum error decrease operation and continue to next pixel location till the end criteria is met. Once the end criteria is met, the updated HTI is saved as a final halftone screen for that gray level and copied as the initial HTI for the next gray level along with CTI pixel values updated to the next gray level till the final gray value is reached.
