Multi-Screen E-Reader Dynamic Image Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
E-readers with high resolution low frequency displays experience frame delay when displaying animations or dynamic images due to insufficient frame per second rates, making it inconvenient for users to browse web pages with rich content.
Innovation Solution
An electronic apparatus with multiple screens, featuring a first display unit with low refresh rate and a second display unit with high refresh rate, where the processing module detects dynamic images in digital files and selectively displays them on the second unit, thereby overcoming frame delay issues and allowing users to choose content display on different windows.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If a high resolution low frequency display is used in e-readers to save energy, then energy consumption is reduced, but frame delay occurs when displaying animations or dynamic images due to insufficient frame per second rate
Solution Approach 1:
The display system is segmented into two separate display units: a first display unit with low refresh rate for energy-saving static content, and a second display unit with high refresh rate for dynamic content. This segmentation allows each display unit to specialize in its optimal function, resolving the contradiction between energy consumption and frame delay by ensuring dynamic images are displayed on the high refresh rate screen while static content remains on the energy-efficient low refresh rate screen
2Measurement precision
If a high resolution low frequency display is used in e-readers, then display resolution is improved, but the display cannot provide sufficient frame per second rate for animations and dynamic images
Solution Approach 1:
Different display units are assigned different refresh rate characteristics tailored to their specific function: the first display unit maintains high resolution with low refresh rate for static content where resolution is paramount, while the second display unit provides high refresh rate for dynamic content where speed is critical. This local quality differentiation resolves the contradiction by allowing each display unit to optimize for its specific requirement rather than requiring a single display to satisfy both conflicting demands
3Device complexity
If the e-reader displays web pages with animations and dynamic images on a single low refresh rate display, then device complexity is kept simple, but user convenience deteriorates due to frame delay
Solution Approach 1:
The system transitions from a single-dimension display approach (one display handling all content) to a multi-dimensional approach with two display units having different characteristics. The processing module automatically detects dynamic content and routes it to the appropriate display unit, adding the dimension of content-type-based display selection. This resolves the contradiction by improving user convenience through appropriate display selection while managing complexity through automated content detection and routing

AI summary
An electronic apparatus with multiple screens and an image displaying method thereof are provided. The image displaying method is adapted to an electronic apparatus. The electronic apparatus includes a first display unit and a second display unit. The image displaying method includes following steps. By a processing module, a digital file is read, and a content of the digital file is displayed on the first display unit. Whether the content of the digital file includes at least one dynamic image is detected by the processing module. When the content of the digital file includes the at least one dynamic image, the at least one dynamic image is displayed on the second display unit by the processing module.
