Display Grayscale Differentiation for Paper-Like Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices cause visual fatigue and decreased vision due to poor visual effects and mirror reflection when used for extended reading sessions, leading to an unsatisfactory user experience.
Innovation Solution
A display method that differentiates the grayscales of background pixels to simulate an effect of diffuse reflection, improving the visual experience by rendering a display similar to a paper book, thereby reducing visual fatigue and enhancing reading comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional display methods are used with uniform background color, then the display is simple to implement and low in cost, but the visual effect is poor and causes visual fatigue
Solution Approach 1:
The patent applies local quality by differentiating the grayscale values of background pixels based on their spatial positions. Instead of using a uniform background color, the display adjusts the luminance of each pixel locally to simulate the diffuse reflection characteristics of paper, creating a more natural reading experience that reduces visual fatigue while maintaining implementation feasibility through software processing.
2Ease of operation
If grayscales of background pixels are differentiated to simulate diffuse reflection, then the reading comfort is improved, but the computational complexity increases
Solution Approach 1:
The patent implements parameter changes by modifying the grayscale values of background pixels according to their spatial coordinates. The display device adjusts the luminance parameter of each pixel based on a mathematical model that simulates paper-like diffuse reflection, thereby improving reading comfort while managing computational complexity through efficient algorithms.
3Use of energy by moving object
If uniform background display is used, then the power consumption is low, but the visual experience is unsatisfactory for extended reading
Solution Approach 1:
The patent applies partial action by selectively adjusting only the background pixel grayscales while keeping the foreground text pixels unchanged. This approach simulates the paper-like reading experience in the background area without unnecessarily processing all pixels, thereby improving visual experience for extended reading while controlling power consumption through targeted processing.
