DDIC Always-On Display Content Element Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart terminals' Display Driver Integrated Circuits (DDICs) face challenges in accurately displaying system time and notification messages when the screen is off, due to a lack of understanding of content element meanings, leading to potential display errors and increased power consumption.
Innovation Solution
The method involves acquiring and analyzing content elements, element meanings, and storage locations within the DDIC to determine and display target information content, such as system time or notification messages, by matching element meanings with corresponding content elements and storage locations, ensuring accurate and power-efficient always-on display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the DDIC displays content elements without understanding their meanings, then the always-on display function can be implemented, but display errors occur due to incorrect content selection
Solution Approach 1:
The patent introduces an element meaning as an intermediary between the content element and the display function. The DDIC acquires not only content elements but also their corresponding meanings and storage locations. This intermediary layer enables the DDIC to understand what each content element represents, allowing accurate selection and display of the intended information without confusion between different content types.
2Loss of information
If the screen remains fully on to display time and notifications, then information is always visible, but power consumption increases
Solution Approach 1:
The patent segments the display into different regions with different power states. The always-on display function displays only essential information (time and notifications) in specific areas while allowing other parts of the screen to remain off or enter low-power mode. This segmentation enables continuous visibility of critical information without requiring the entire screen to remain active, thus reducing overall power consumption.
3Measurement precision
If the DDIC autonomously selects content elements, then display accuracy improves, but device complexity increases due to additional processing requirements
Solution Approach 1:
The patent applies preliminary action by having the system acquire and organize content elements, their meanings, and storage locations before the actual display operation. The DDIC receives pre-packaged information including content elements with their associated metadata (meanings and storage locations), which allows for accurate autonomous selection without requiring complex real-time processing or decision-making algorithms during display operations.

AI summary
The present disclosure discloses a method and apparatus for always-on display, and a computer-readable storage medium. The method includes: acquiring a plurality of content elements, a plurality of element meanings and a plurality of storage locations required for the always-on display, where each content element corresponds to an element meaning and a storage location; determining target information content, where the target information content needs to be displayed through an always-on display function; acquiring a content element required for displaying the target information content from the plurality of content elements based on the target information content, the plurality of element meanings, and the plurality of storage locations; and displaying the target information content through the always-on display function based on the acquired content element.
