Electronic Shelf Label Flash Layout for Low-Cost Dynamic Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic shelf label devices face challenges in presenting dynamic content due to high costs associated with LCD screens and low refresh rates of electronic ink screens, which are not suitable for animations or videos.
Innovation Solution
Implement a storage structure in the electronic shelf label device with a high-speed and low-speed flash memory units, allowing dynamic images to be presented in one region and static content in another, using a microcontroller to manage data storage and presentation, and optimizing image data format to reduce storage requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LCD screen is used to present dynamic content, then dynamic image presentation capability is improved, but device cost increases greatly
Solution Approach 1:
The screen is divided into a first region for displaying dynamic images and a second region for displaying static content. This segmentation allows the system to use different display technologies or modes in different regions, enabling dynamic content presentation in the first region while maintaining cost-effectiveness through the second region's static display capability.
Solution Approach 2:
The patent implements dynamic image presentation by sequentially refreshing image sequences in the first region at specific time intervals. This dynamic refresh approach enables animation and video content without requiring a fully dynamic display technology across the entire screen, thereby reducing overall device cost while maintaining dynamic content capability.
2Ease of manufacture
If electronic ink screen is used, then device cost is reduced and power consumption is low, but refresh rate is excessively low and cannot present dynamic content
Solution Approach 1:
The screen is divided into a first region for displaying dynamic images and a second region for displaying static content. This segmentation allows the first region to operate with higher refresh rates for dynamic content while the second region maintains the low-power static display characteristics, effectively resolving the contradiction between refresh rate and power consumption/cost.
Solution Approach 2:
The patent implements periodic refreshing of image sequences in the first region at controlled time intervals to create dynamic content presentation. This periodic refresh strategy enables the system to achieve acceptable dynamic content display without requiring continuously high refresh rates across the entire screen, thereby maintaining cost-effectiveness and power efficiency.
