  • Patent number: 10318041
    Abstract: A signal processor implements a technique for detecting objects on a panel which transmits signals inside the panel such that the objects are allowed to interact with (e.g. attenuate) the signals by contact with a touch surface of the panel. The signal processor operates to define cells that have a given location on the touch surface and are associated with a respective set of intersecting paths for the signals across the touch surface. The signal processor operates to obtain (90) an output signal from a signal detection arrangement that measures a signal property for each path; process (91) the output signal to obtain an interaction value for each path; and generate (93-95?) a cell value of a selected cell among the cells as either a robust measure of central tendency (e.g. a median) or a minimum/maximum among the interaction values for the intersecting paths. The signal processor determines (97) presence or absence of an object in the selected cell based on the cell value.

  • Patent number: 10311808
    Abstract: A system for calibrating a liquid crystal display (LCD) includes a plurality of temperature sensors, a storage medium, and a controller. Each temperature sensor measures a current temperature of at least one pixel in the LCD. The storage medium stores information about latencies for any LC-based pixel, wherein each latency corresponds to a time period for transition from a starting to an ending illumination state for one temperature of the LC-based pixel. The controller determines, based on the current temperature, the transition information and frame information, a time for each pixel in at least a portion of the LCD to transition from a first to a second illumination state. The controller computes, based on transition times, an LC transition time for at least the portion of the LCD and performs calibration of at least the portion of the LCD based on the LC transition time.

  • Patent number: 10254815
    Abstract: Power consumption of a device having a resistive touch screen may be reduced if the resistive touch screen is not scanned unless a touch thereto is imminent, especially if the device can remain in a low power sleep mode during no-touch inactivity. Furthermore, detecting a potential touch earlier then an actual first touch may improve initial touch response time. The resistive touch screen may comprise top and bottom Indium Tin Oxide (ITO) coated planes. The top ITO coated plane may be used as a capacitive proximity detector and the bottom ITO coated plane may be used as a guard shield for the top ITO coated plane to significantly reduce parasitic capacitance thereof and enhance the sensitivity of capacitive proximity detection. The device may also remain in a low power sleep mode until a potential touch is detected thereby further saving device power consumption.
