Camera-Under-Display State Indicators for Privacy Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Camera-Under-Display configurations, users face difficulty in determining the active or inactive state of the camera due to the absence of dedicated status indicator lights, which is a concern for privacy and functionality awareness.
Innovation Solution
A computer system and method utilizing a vision chip independent from the system processor to process camera image data, update the system state, and instruct the display driver to display system state indicator symbols, even when the system is in sleep mode, ensuring user awareness of camera activity and privacy modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a camera is disposed under the display panel without dedicated status indicator lights, then the display-to-body ratio is improved and bezel is eliminated, but the user cannot easily determine whether the camera is active or inactive
Solution Approach 1:
The patent merges the camera status indication function with the display panel by showing state indicator symbols directly on the display. The processing system combines camera activity detection with display output control, eliminating the need for separate indicator lights while providing clear visual feedback about camera state through symbols displayed on the screen.
Solution Approach 2:
The display panel serves multiple functions: it displays normal content and simultaneously indicates camera state through state indicator symbols. The processing system manages both functions, allowing the display to communicate system status without requiring dedicated indicator components, thus maintaining the bezel-less design while providing necessary information.
2Device complexity
If the system processor processes camera image data and controls display, then system coordination is simplified, but power consumption increases and response speed decreases
Solution Approach 1:
The patent segments the processing system into distinct functional components: a processing system that handles high-level decisions and a vision chip that independently processes camera image data and controls display output. This segmentation allows the vision chip to operate autonomously with lower power consumption while the main processing system remains available for complex tasks, resolving the trade-off between coordination simplicity and power efficiency.
Solution Approach 2:
The vision chip acts as an intermediary between the camera and display, independently processing image data and controlling display output without requiring constant intervention from the main system processor. This intermediary approach reduces the power consumption burden on the main processor while maintaining system coordination through the vision chip's autonomous operation.

AI summary
A computer system includes a display panel, at least one camera disposed under the display panel, and a processing system. The processing system includes a display driver circuit, a system processor, and a vision chip. The vision chip, independently from the system processor, processes image data captured by the at least one camera through the display panel, updates a state of the computer system based on the image data, and instructs the display driver circuit to drive the display panel to display a system state indicator symbol indicating the state of the computer system.
