E-paper Display Screen for Concussion Patients
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current guidelines for mild traumatic brain injury recovery are unclear, and LCD screens exacerbate symptoms like photophobia, leading to cognitive fatigue, headaches, and delayed recovery in concussion patients, with no effective method to improve computer tolerance and reduce recovery time.
Innovation Solution
A display screen that modifies parameters such as refresh rate, color, and content presentation using e-paper technology to reduce negative side effects, allowing users to view content in black-and-white, grayscale, with enhanced contrast and reduced animation, and adjustable font sizes, which can be configured to fit over existing screens or attach using clips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LCD screens are used for daily communication and work, then accessibility and connectivity are improved, but concussion patients experience exacerbated symptoms including photophobia, cognitive fatigue, and headaches
Solution Approach 1:
The patent applies parameter changes by modifying the refresh rate from the standard 60Hz to lower rates (e.g., 1Hz, 10Hz, or variable rates), adjusting brightness levels, and controlling color output to reduce photophobia and symptom exacerbation in concussion patients while maintaining computer functionality
Solution Approach 2:
The patent introduces an intermediary device or software layer that sits between the user and the LCD screen, mediating the display output by filtering and adjusting parameters in real-time to protect sensitive users from harmful effects while preserving access to digital content
2Speed
If LCD screens refresh at 60 times per second, then image quality and smoothness are improved, but concussion patients with photosensitivity experience lower critical flicker frequency tolerance and increased cognitive fatigue
Solution Approach 1:
The patent implements dynamic refresh rates that can vary based on user needs and task requirements, allowing the system to switch between higher refresh rates for normal users and lower rates for concussion patients, or adjust rates in response to detected symptom severity or task type
3Illumination intensity
If LCD backlighting is used, then screen visibility is improved, but concussion patients experience stress, cognitive fatigue, headache, and eye fatigue
Solution Approach 1:
The patent applies parameter changes by significantly reducing backlight intensity or eliminating it entirely in favor of reflective display technologies, while compensating for visibility through ambient light utilization and high-contrast content rendering
4Productivity
If flashing and motion are displayed on screens, then content engagement and information delivery are improved, but concussion patients become nauseated and recovery is delayed
Solution Approach 1:
The patent extracts or removes flashing and motion elements from the display content specifically for concussion patients, delivering only static or minimally animated information to prevent nausea while maintaining essential information delivery capabilities

AI summary
Provided are display screens for electronic devices and methods for displaying content on electronic devices, that are particularly suitable for users who are suffering from or recovering from a concussion or mild traumatic brain injury (MTBI), migraine, or computer vision syndrome. Embodiments comprise a component that modifies at least one parameter of content that is displayed on the display screen, wherein the modified displayed content reduces, minimizes, or eliminates negative side effects of users. Embodiments may include computer executable programmed instructions stored on a non-transitory computer readable storage medium that direct a processor to modify at least one parameter of content that is displayed on a display screen of an electronic device, and/or to implement a simplified graphical user interface. One embodiment is implemented using an e-paper display screen.
