Partial Display Activation for Standby Notifications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia devices lack the ability to provide customized information to users when in standby or ON mode, failing to efficiently utilize power and deliver personalized content.
Innovation Solution
A multimedia device equipped with a controller, notification information collection unit, sensing unit, and display unit that activates a partial display area to show customized notification information based on recognized users and their distance, even when the device is in standby mode, and continues to provide notifications through a mobile terminal when the user is out of range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the multimedia device activates the display unit in standby mode to provide notification information, then user convenience and information delivery are improved, but power consumption increases
Solution Approach 1:
The display unit is divided into a first display area and a second display area. The first display area remains active in standby mode to show notification information, while the second display area remains inactive to conserve power. This segmentation allows the device to provide useful information without activating the entire display, thus resolving the contradiction between user convenience and power consumption.
Solution Approach 2:
Instead of activating the entire display unit or no display at all, the patent applies partial action by activating only the necessary first display area in standby mode. This provides sufficient information to users while minimizing power consumption, avoiding the extremes of full activation or complete inactivation.
2Adaptability or versatility
If the multimedia device provides customized notification information for recognized users, then information personalization is improved, but device complexity increases
Solution Approach 1:
User recognition and notification customization are performed in advance through preliminary user information acquisition and storage. The system pre-stores multiple sets of notification information corresponding to different users, and when a user approaches, the system quickly retrieves and displays the appropriate pre-prepared information. This eliminates the need for complex real-time analysis and reduces device complexity while maintaining personalization.
Solution Approach 2:
The system creates simplified copies of user-specific notification information templates that are stored in advance. Instead of generating complex personalized content in real-time, the system copies and displays pre-formatted notification sets associated with each user, reducing computational complexity while maintaining information personalization.

AI summary
A multimedia device capable of providing notification information for each user in a standby mode is disclosed. The multimedia device according to one embodiment of the present invention comprises: a control unit entering the standby mode when the multimedia device is turned off; a notification information collection unit for collecting notification information from at least one of a broadcasting station, an external device, and an external server when the multimedia device has entered the standby mode; a sensing unit for acquiring user information and information of distance with the user when the multimedia device has entered the standby mode; and a display unit, wherein, when a user recognized on the basis of the acquired user information corresponds to a preset user, and when the acquired information of distance with the user corresponds to a preset distance value, the control unit activates a partial region of the display unit and displays, on the activated partial region, notification information corresponding to the recognized user from among the pieces of collected notification information.
