Display System Adjusting Luminance for Colored Protective Eyewear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearing protective eyeglasses with colored lenses reduces the visibility of display screens, leading to potential errors in operating user interfaces due to decreased luminance and color similarity, which existing technologies have not adequately addressed.
Innovation Solution
A display system that includes an information acquisition unit, a display control unit, and a display unit, where the operator can input wearing information and color information of the eyewear, allowing the system to adjust the color map and luminance of the display to maintain appropriate contrast and visibility even when wearing colored lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective eyeglasses with colored lenses are worn to protect eyes from laser light, then eye protection is improved, but display screen visibility deteriorates due to decreased luminance and color similarity
Solution Approach 1:
The system changes the display parameters (color map and luminance) based on the eyewear's transmission characteristics. By acquiring the transmission spectrum of the eyewear and calculating optimal display parameters that compensate for the color filtering effect, the system maintains visibility while the user wears protective colored lenses.
Solution Approach 2:
The system acquires transmission characteristics of the eyewear and uses this information to adjust display settings. This feedback mechanism allows the display to adapt to the user's viewing conditions through the colored lenses, ensuring optimal visibility while maintaining eye protection.
2Object-affected harmful factors
If protective eyeglasses with colored lenses are worn to reduce laser light transmittance, then laser safety is improved, but user interface operability deteriorates due to difficulty in viewing UI elements with similar colors
Solution Approach 1:
The system adjusts the color map parameters of the display based on the eyewear's transmission spectrum. This ensures that UI elements maintain sufficient color contrast and visibility when viewed through the colored protective lenses, preventing operation errors while maintaining laser safety.
3Reliability
If colored lenses are used to filter specific wavelength bands of laser light, then laser protection is improved, but overall display luminance deteriorates making the screen appear darker
Solution Approach 1:
The system increases the luminance parameter of the display to compensate for the light absorption by the colored lenses. By calculating the transmission characteristics of the eyewear, the system adjusts display brightness to maintain adequate luminance levels while preserving the protective filtering function of the lenses.
