  • Patent number: 10553177
    Abstract: The present disclosure provides devices and techniques for dynamically adjusting the bias voltage (V) levels (e.g., low level gate voltage (VGL) and high level gate voltage (VGH)) for display screens made with thin-film transistor (TFT) technology based on a display run time. Thus, as the positive bias temperature stress for the TFTs increases over the course of the display lifetime, features of the present disclosure adjust the bias voltage levels to maintain operation margin (e.g., the ratio between the high level gate voltage (VGH) value and the voltage value which the display can maintain with normal operation). By dynamically adjusting the bias voltage levels, the TFT displays of the present disclosure consume lower power than their conventional counterparts and improve the lifetime of the display itself.

  • Patent number: 8294691
    Abstract: A method and apparatus are provided for detecting activation of a touch panel. The method includes the steps of providing an N by M touch panel including a matrix of N rows of touch elements along a first axis and M columns of touch elements along a second axis, providing N optical beams 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 is different than the summation the corresponding characteristic of any other N beams 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.

  • Publication number: 20100123683
    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.
