Display Controller Pixel Segmentation for Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In display devices, the presence of camera modules or sensors interrupts the image display area, leading to incomplete images and increased bezel size, as well as interference from light generated by the display panel when the camera is operated.
Innovation Solution
A controller is used to manage display area information and border information for pixels, allowing the image to be adjusted and displayed even in areas overlapping with camera modules, by dividing the display panel into separate areas with different pixel configurations and controlling the image processing based on the operation of the optical module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera module is mounted in the display area, then the camera function is integrated, but the image display is interrupted and the bezel area increases
Solution Approach 1:
The display panel is divided into a first display area with normal pixel configuration and a second display area overlapping the camera module with different pixel configuration. This segmentation allows the camera to be integrated while maintaining image display continuity across the boundary by processing border pixels differently.
Solution Approach 2:
Different pixel configurations are applied to different areas of the display panel. The first display area uses standard pixels while the second display area uses pixels adapted for camera integration. Border pixels between these areas receive special processing to ensure smooth transitions and prevent visible discontinuities.
2Stability of the object's composition
If display area information and border information are generated for all pixels, then image continuity is maintained, but processing complexity increases
Solution Approach 1:
Pixels are segmented into three categories: first pixels in the first display area, second pixels in the second display area, and border pixels between them. This segmentation allows targeted processing where only border pixels require special attention for maintaining image continuity, reducing overall processing complexity compared to treating all pixels uniformly.
Solution Approach 2:
Different processing strategies are applied to different pixel types. Border pixels receive special processing to ensure continuity, while interior pixels in each display area use standard processing methods. This localized approach maintains image quality without unnecessarily complicating the processing of all pixels.
3Stability of the object's composition
If the display panel is divided into separate areas with different pixel configurations, then image display continuity is achieved, but device complexity increases
Solution Approach 1:
The display panel is segmented into distinct first and second display areas with different pixel configurations to accommodate the camera module. This physical segmentation enables image continuity by allowing each area to be optimized for its specific function while maintaining overall visual coherence through border pixel processing.
Solution Approach 2:
The display panel serves multiple functions: displaying images in the first display area, providing camera integration in the second display area, and maintaining continuity through border pixel processing. This multi-functionality is achieved within a single unified display structure rather than requiring separate components.

AI summary
Disclosed is a display device including a display panel having a plurality of pixels, the display panel comprising a first display area and a second display area, the second display area being disposed so as to overlap an optical module, and a controller configured to generate display area information of each of the plurality of pixels and border information of pixels provided in a border area located within a predetermined range from a border between the first display area and the second display area, to change an image that is displayed in at least one of the first display area or the second display area based on the display area information and the border information upon determining that the optical module is operated, and to perform control such that the changed image is displayed on the display panel.
