Dynamic Display Area Shielding for Camera Light Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with display screens and camera modules face image distortion due to light from the display area entering the camera module through openings, which affects the imaging quality when the camera is active.
Innovation Solution
A display control method and device that adjust the state of the display area surrounding the camera module's opening based on the camera's ON/OFF state, shielding light when the camera is active and allowing normal display when it's inactive, using liquid crystal or self-luminous display panels to manage light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display area is increased by providing an opening for the camera module, then the display area is increased, but light from the display area enters the camera module causing image distortion
Solution Approach 1:
The display area surrounding the camera opening is dynamically adjusted based on camera activity state. When the camera is active, the display area is reduced or shielded to prevent light interference; when the camera is inactive, the display area is restored to its normal size. This dynamic adjustment resolves the contradiction by making the display area adaptive to camera usage conditions.
Solution Approach 2:
The display panel is divided into different regions: a first display area surrounding the camera opening and a second display area. The first display area is selectively adjusted or shielded when the camera is active, while the second display area continues to function normally. This local differentiation allows the system to prevent light interference in the critical region while maintaining overall display functionality.
2Object-affected harmful factors
If the display area is reduced to shield light from entering the camera opening, then light interference is reduced, but the display area decreases
Solution Approach 1:
The display area is dynamically adjusted based on camera activity rather than being permanently reduced. When the camera is active, the first display area is temporarily shielded or reduced; when the camera is inactive, the display area is restored to its full size. This temporal dynamic adjustment resolves the contradiction by making the display area adaptive to real-time camera usage conditions.
Solution Approach 2:
The display area undergoes periodic adjustment corresponding to camera activation and deactivation cycles. The system alternates between a first state (reduced/shielded display area) when the camera is active and a second state (full display area) when the camera is inactive. This periodic action allows the system to maintain large display area overall while temporarily reducing it only when necessary for camera operation.
3Ease of operation
If the camera module is positioned to obtain light through the opening, then the camera function is enabled, but light from the display area causes image distortion
Solution Approach 1:
The display area surrounding the camera opening is dynamically controlled based on camera activity state. When the camera is active, the display area is reduced or shielded to prevent light interference; when the camera is inactive, the display area is restored to its normal size. This dynamic adjustment resolves the contradiction by making the display area adaptive to camera usage conditions.
Solution Approach 2:
The display panel is divided into different regions: a first display area surrounding the camera opening and a second display area. The first display area is selectively adjusted or shielded when the camera is active, while the second display area continues to function normally. This local differentiation allows the system to prevent light interference in the critical region while maintaining overall display functionality.

Function Achieved in This Case
This solution reduces light interference with the camera module's image capturing, enhancing image quality and increasing the display area by dynamically controlling the display panel's light emission in response to the camera's state.
Implementation Method 1
adjusting deflection angles of liquid crystal molecules corresponding to the first display area in the liquid crystal display panel to shield light emitted from a backlight sheet in the liquid crystal display panel such that the first display area displays black

AI summary
An electronic apparatus includes: a display panel having an opening, a first display area surrounding at least a portion of the opening, and a second display area different from the first display area; and a camera module disposed corresponding to the opening to obtain light through the opening. A display control method for the electronic apparatus includes: obtaining an ON/OFF state of the camera module; and adjusting a working state of the first display area in accordance with the ON/OFF state of the camera module, wherein the first display area is adjusted to a first state so as to shield at least a portion of light from entering the opening when the camera module is in ON state, and the first display area is adjusted to a second state when the camera module is in OFF state.
