Camera Module Image Compensation in Display Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of a camera module or sensor module into the edge of a smartphone's display disrupts the viewing experience by creating a heterogeneous interface with the screen, particularly when the module is positioned in a notch, leading to a black portion that obstructs the screen display.
Innovation Solution
A method is implemented to compensate for the image around the camera module or sensor module by adjusting pixel values and applying effects such as vignette or blur to minimize visibility, allowing the screen to be extended up to the module's position without disturbing the viewing experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the display area is increased by extending the display to include the camera module region, then the screen size is improved, but the viewing experience deteriorates due to the heterogeneous interface between the screen and camera module
Solution Approach 1:
The patent applies color matching techniques to adjust the appearance of the camera module region to match the surrounding display content. By dynamically changing the color or brightness of pixels around the camera module, the heterogeneous interface is reduced, making the camera module less visually prominent and improving the overall viewing experience while maintaining the extended display area.
Solution Approach 2:
The patent modifies display parameters such as brightness, contrast, and color values in the regions adjacent to the camera module. By dynamically adjusting these parameters based on the displayed content and camera module position, the visual heterogeneity is minimized, allowing the display to extend into the camera region without significantly degrading the viewing experience.
2Adaptability or versatility
If a notch is defined in the front surface to accommodate the camera module, then the camera module integration is improved, but the screen display deteriorates due to the black portion obstructing the display
Solution Approach 1:
The patent applies color matching to the notch region by adjusting the brightness and color of pixels surrounding the camera module. This makes the black portion less visually prominent by matching it with the surrounding display content, thereby reducing the obstruction effect and effectively increasing the usable screen display area while maintaining camera module integration.
Solution Approach 2:
The patent converts the harmful effect of the black notch portion into a beneficial visual effect by using color matching techniques. The previously obtrusive black area is transformed into a visually integrated region that blends with the surrounding display content, turning the structural limitation into an aesthetic feature that does not significantly reduce the effective screen area.
3Ease of operation
If image compensation is applied around the camera module to reduce viewing disturbance, then the viewing experience is improved, but the image processing complexity increases
Solution Approach 1:
The patent applies image compensation techniques selectively only to the regions immediately adjacent to the camera module, rather than processing the entire display. By focusing the image processing on local areas where the heterogeneity is most pronounced, the viewing experience is improved while the overall processing complexity is kept manageable through targeted rather than universal application.
