Abstract:
A computing device includes a display having a striped polarizer, the striped polarizer includes a set of sub-areas having a first polarization interspersed between another set of sub-areas having a second polarization. The sub-areas are arranged to provide an alternating polarization across a dimension of the display. The computing device may be configured to receive information specifying a privacy display mode, select a privacy display mode based upon the received information, receive input display data configured to represent information for display, generate, in response to selecting the privacy display mode, output display data by inverting a first portion of pixels in the input display data which are associated with a first polarization, and not inverting a second portion of pixels in the input display data which are associated with a second polarization, and provide the output display data to a display.

Abstract:
The disclosure relates to the technical field of capacitive touch panels and discloses a touchpen which may be used in mobile phones, computers and other devices with touch panels for writing characters, letters and other symbols. In particular it relates to a capacitive touchpen 10 for inputting information into an electronic device 1 through touching of a capacitive touch panel 30, the capacitive pen comprising an elongated body member 11 comprising a conductive part 13 and a tip 12 disposed at one end of the body member 11 having a contact surface 14 for contacting the capacitive touch panel 30. The conductive part 13 is configured such that the distortion of the touch panel's electrostatic field caused by the conductive part 13 when changing the position of the touchpen 10 in relation to the capacitive touch panel 30, when the contact surface is kept in contact with the touch panel 30, is sufficient to register a change in capacitance by the capacitive touch panel 30. The disclosure further relates to methods for detecting the position of a touch pen as well as to an electronic device and a computer program.
