SWITCHABLE PRIVACY DISPLAY BASED ON STRIPED POLARIZER
First Claim
1. A method for selectively displaying content on a computing device, comprising:
- receiving information to specify a privacy display mode;
selecting the privacy display mode based upon the received information;
receiving input display data configured to represent information for display;
generating, 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
providing the output display data to a display.

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.
