Eyewear Optical Elements for Display Contrast in Bright Light
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face performance limitations when displaying screens in bright ambient lighting conditions due to interference from ambient light, which diminishes perceived brightness and clarity.
Innovation Solution
The use of an eyewear device with optical elements, such as filters and active shutters, that block ambient light interference while allowing light from the display to pass through, improving contrast and reducing energy consumption by synchronizing transparency with the display's output timing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display screen is viewed in bright ambient lighting conditions, then the display can be used outdoors or in well-lit environments, but the perceived contrast and brightness are diminished due to ambient light interference
Solution Approach 1:
The patent introduces optical elements (filters, shutters) as intermediary components between the ambient light and the display screen. These elements selectively block harmful ambient light wavelengths while allowing display light to pass through, thereby mediating the interaction between ambient lighting conditions and display visibility to maintain perceived brightness and contrast
2Illumination intensity
If the display increases brightness to compensate for ambient light, then the perceived contrast improves, but the energy consumption increases
Solution Approach 1:
The patent converts the harmful effect of ambient light into a beneficial filtering process. By using optical elements to block ambient light wavelengths, the system eliminates the need for high display brightness compensation, thereby maintaining perceived contrast while reducing energy consumption that would otherwise be required to overcome ambient light interference
3Illumination intensity
If optical elements are added to block ambient light, then the perceived contrast improves, but the device complexity increases
Solution Approach 1:
The patent designs optical elements that serve multiple functions: filtering ambient light, allowing display light transmission, and potentially providing additional features like UV protection or glare reduction. This multi-functionality reduces the need for separate components, thereby managing device complexity while achieving improved perceived contrast
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
Enhances the perceived contrast and brightness of display screens in bright environments, reducing energy usage and improving battery life by limiting ambient light interference and optimizing display settings.
Implementation Method 1
The optical element may comprise at least one filter, for example a narrowband filter, corresponding to light generated by a display. The at least one filter may be incorporated into an optical element of the device. The at least one filter may further allow wavelengths corresponding to one or more display primaries of a display to pass through the optical element, but may block wavelengths away from the wavelengths of the one or more display primaries or other wavelengths.
Implementation Method 2
The device may incorporate active shutters. The shutters may be operable to synchronize a transparency of at least one optical element with an output timing of light emitted from a display device.
