Secondary Camera-Top Screen for Off-Screen Notifications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a mobile phone's primary screen is turned off, notification messages are difficult for users to notice, especially when the device is placed horizontally, leading to a poor user experience due to the placement of indicators on the top or side, which are not easily visible.
Innovation Solution
The implementation of a secondary screen located above the front-facing camera to display prompt information for notification messages, allowing users to easily notice messages even when the primary screen is off, and providing continuous information display when the primary screen is turned on, thus improving user experience and resolving discontinuity issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the indicator is placed on the top or side of the mobile phone to reduce screen space occupation, then the screen-to-body ratio is improved, but the notification message becomes difficult to be noticed by the user when the screen is turned off
Solution Approach 1:
The display is segmented into a primary screen and a secondary screen. The secondary screen is specifically positioned above the camera to display notification information, separating the notification function from the main screen area. This allows the primary screen to maintain its full display area while the secondary screen handles notification visibility.
Solution Approach 2:
The secondary screen acts as an intermediary between the notification system and the user. When the primary screen is off, the secondary screen mediates the notification delivery by displaying prompt information above the camera, making notifications visible without requiring the primary screen to be on or occupying additional screen space.
2Area of moving object
If the indicator is placed on the top or side of the mobile phone, then the screen-to-body ratio is improved, but the notification message is difficult to be noticed when the mobile phone is placed horizontally
Solution Approach 1:
The notification display is moved from the traditional horizontal screen area to a vertical position above the camera. This dimensional change allows notifications to be visible in a different spatial plane, making them detectable even when the phone is held horizontally, as the secondary screen remains in a fixed position above the camera regardless of phone orientation.
3Ease of operation
If a secondary screen is added above the camera to display notification information, then notification visibility is improved, but the device structure becomes more complex
Solution Approach 1:
The secondary screen is merged with the existing display hardware infrastructure. It uses the same display panel technology and control system as the primary screen, sharing the display controller and power supply. This merging approach allows the secondary screen to function as an additional display area without requiring completely separate hardware systems, thereby limiting the increase in device complexity.

AI summary
A message notification method and an electronic device are provided. When a primary screen is turned off, prompt information of a notification message is displayed on a secondary screen located right above a front-facing camera, so that a user can notice a message notification in time, and user experience is improved. A specific solution is as follows: After the primary screen is turned off, if the electronic device detects a first notification message, the electronic device displays first information on the secondary screen. The first information is used to prompt the user that the first notification message has been received. The electronic device detects a first operation in which the user indicates to turn on the primary screen. The electronic device turns on the primary screen in response to the first operation. The electronic device displays second information on the secondary screen.
