Angled Display Mounting for Head-Mounted Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The physical limitations of pixel size on display screens, particularly in head-mounted displays, restrict the perceived resolution when viewed head-on, limiting the image quality due to fixed dot pitch and viewing angle constraints.
Innovation Solution
Mounting display screens at an angle relative to the user's intended viewing position, allowing for a non-perpendicular viewing angle, which increases the perceived pixel density and resolution by presenting more pixels per unit area than if viewed straight on.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display is mounted perpendicular to the user's viewing position, then the viewing geometry is simple and straightforward, but the perceived pixel density and resolution are limited by the physical dot pitch
Solution Approach 1:
The patent applies dimensionality change by rotating the display from a perpendicular (90-degree) mounting to an angled mounting relative to the user's viewing direction. This changes the geometric dimension of the display orientation, allowing the user to view more pixels across the display surface at an angle, thereby increasing perceived resolution without changing the physical pixel density or adding mechanical complexity to the display structure itself.
2Measurement precision
If the display is mounted at an angle to increase perceived pixel density, then more pixels are observed per unit area, but the mounting structure becomes more complex and requires additional space
Solution Approach 1:
The patent applies parameter changes by modifying the mounting angle parameter of the display relative to the user's viewing direction. By changing this geometric parameter from 90 degrees to a different angle, the system optimizes the number of pixels visible to the user per unit area, thereby improving perceived pixel density while maintaining a relatively simple mounting structure that does not require complex mechanical mechanisms.
3Measurement precision
If the display is mounted at an angle, then the perceived resolution increases, but the depth of the display housing increases
Solution Approach 1:
The patent applies dimensionality change by rotating the display in a different spatial dimension (angular orientation) rather than increasing the depth of the housing. This allows the display to be mounted at an angle that optimizes pixel visibility while keeping the housing depth minimal, as the angle is achieved through rotational mounting rather than extended depth.

AI summary
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.
