VR Goggles Optical Lens Sequential Projection Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality goggles provide low picture resolution as each eye can only see half of the display screen, resulting in a compromised viewing experience.
Innovation Solution
The implementation of an optical lens positioned between a buffer layer and a display screen within a shell, allowing the whole display screen to be projected to one eye at a time, with optional light valves to prevent light leakage, thereby doubling the picture resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display screen is divided into two display areas for each eye, then each eye can see its designated area, but the picture resolution becomes relatively low
Solution Approach 1:
The patent merges the display areas for both eyes into a single display screen. The optical lens then directs the entire display screen content to one eye at a time through sequential projection, eliminating the need to divide the display screen into separate areas for each eye. This combining approach doubles the picture resolution while maintaining the functionality of providing separate visual content to each eye.
Solution Approach 2:
The patent employs periodic action by controlling the optical lens to project the display screen content to the left eye and right eye alternately at different time moments. This time-sequential projection method allows a single display screen to serve both eyes without physical division, achieving higher resolution while maintaining the stereoscopic viewing function.
2Measurement precision
If the optical lens projects the whole display screen to one eye at a time, then the picture resolution is doubled, but light leakage may occur affecting viewing quality
Solution Approach 1:
The patent introduces a light valve as an intermediary component between the display screen and the eyes. The light valve controls light transmission selectively, blocking light from reaching the eye that is not currently being projected to, while allowing light to pass through to the active eye. This intermediary mechanism prevents light leakage without compromising the doubled picture resolution achieved through whole-screen projection.
3Reliability
If a buffer layer is added to block ambient light, then viewing comfort improves, but device complexity increases
Solution Approach 1:
The patent makes the light valve serve multiple functions: it acts as a light blocking mechanism to prevent light leakage to the non-active eye, and simultaneously functions as a buffer layer to block ambient light from affecting the viewing experience. This multi-functionality approach improves viewing comfort without significantly increasing device complexity, as it repurposes an existing component rather than adding a separate dedicated buffer layer.
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
This configuration enables a single eye to see the entire display screen, significantly improving picture resolution to twice that of conventional virtual reality goggles, while minimizing light leakage and enhancing the viewing effect.
Implementation Method 1
an optical lens, wherein the display screen and the optical lens are located within the shell, a buffer layer is formed on a side of the shell facing the viewing human eyes, the optical lens is located between the buffer layer and the display screen, for projecting a picture of the whole display screen only to the left eye or the right eye at the same moment

AI summary
The present invention relates to the field of display technology, and discloses virtual reality goggles and a display method thereof. The virtual reality goggles comprise: a shell, a display screen and an optical lens, wherein the display screen and the optical lens are located within the shell, a buffer layer is formed on a side of the shell facing towards viewing eyes, the optical lens is located between the buffer layer and the display screen, for projecting a picture of the whole display screen only to the left eye or the right eye at a time. The virtual reality goggles of the present invention, by controlling the optical lens to project the picture of the whole display screen only to one eye at a time, enables a single eye to see the picture of the whole display screen. And compared to the conventional goggles through which a single eye can only see half of the picture of the display screen, the picture resolution of the goggles of the present invention is doubled.
