3D Display Content Control for Non-Glass Viewers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Viewers without 3D glasses experience fuzzy 2D content when watching 3D images or videos, which can deter them from purchasing 3D glasses, and providers want to encourage this by making 2D content less desirable.
Innovation Solution
A method and apparatus to control the content and presentation of 3D displays, allowing 3D glass wearers to see 3D content while non-3D glass wearers see 2D content by manipulating the images, timing, and polarization of the right and left eye images, and shuttering of lenses, ensuring the non-3D glass wearers see a less desirable version.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If 3D images or video content is displayed for viewers wearing 3D glasses, then 3D glass wearers can see clear 3D content, but non-3D glass wearers see fuzzy 2D content which is undesirable
Solution Approach 1:
The display content is segmented into separate left-eye and right-eye image sequences that are presented alternately. Each eye's content is displayed during its designated time slot, allowing 3D glasses to direct the appropriate image to each eye while non-wearers see a blurred composite of alternating images.
Solution Approach 2:
The system uses periodic alternation between left-eye and right-eye image display at a frequency synchronized with the 3D shutter glasses. The images are displayed in rapid succession (e.g., left eye then right eye, repeated), creating the 3D effect for wearers while appearing as fuzzy motion to non-wearers.
2Ease of operation
If 2D content is displayed clearly for non-3D glass wearers, then they can watch satisfactory 2D content, but this reduces the incentive to purchase 3D glasses
Solution Approach 1:
The system changes the temporal display parameters by alternating between left and right eye images rather than displaying a stable 2D image. This parameter change ensures that non-wearers see alternating content that appears fuzzy and less desirable, while 3D glass wearers receive the full 3D experience.
3Measurement precision
If content is displayed alternately to left and right eyes for 3D effect, then 3D glass wearers see clear 3D images, but non-3D glass wearers perceive even fuzzier content
Solution Approach 1:
The 3D shutter glasses act as an intermediary device that filters and directs the alternating left and right eye images to the appropriate eyes. This intermediary allows the system to display alternating content that provides clear 3D images for wearers while appearing as fuzzy, indistinct content to non-wearers.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables 3D glass wearers to enjoy clear 3D content while non-3D glass wearers see a less fuzzy 2D version, potentially encouraging the purchase of 3D glasses by making 2D content less appealing.
Implementation Method 1
the polarization of the right eye image (for polarization based 3D), the polarization of the left eye image (for polarization based 3D)
Implementation Method 2
the shuttering of the right lens (for shutter based 3D), the shuttering of the left lens (for shutter based 3D)

AI summary
Embodiments of the invention pertain to a method and apparatus for controlling what non-3D glass wearers see from a 3D display. Such control is accomplished by controlling the images displayed on a 3D display, which allows a 3D-glass wearer to see a 3D image and/or video content while controlling one or more of the following: the content of the right eye image, the left eye image, the timing of displaying the right eye image, the timing of displaying the left eye image, the polarization of the right eye image (for polarization based 3D), the polarization of the left eye image (for polarization based 3D), the shuttering of the right lens (for shutter based 3D), the shuttering of the left lens (for shutter based 3D), and other images displayed not available to the 3D glass wearer, and/or controlling other aspects of the presented images and/or presentation of the presented images.
