  • Patent number: 11350080
    Abstract: Methods and apparatus for using a display in a manner which results in a user perceiving a higher resolution than would be perceived if a user viewed the display from a head on position are described. In some embodiments one or more displays are mounted at an angle, e.g., sometimes in range a range from an angle above 0 degrees to 45 relative to a user's face and thus eyes. The user sees more pixels, e.g., dots corresponding to light emitting elements, per square inch of eye area than the user would see if the user were viewing the display head on due to the angle at which the display or displays are mounted. The methods and display mounting arrangement are well suited for use in head mounted displays, e.g., Virtual Reality (VR) displays for stereoscopic viewing (e.g., 3D) and/or non-stereoscopic viewing of displayed images.
