Display Device Black Border Removal and Screen Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display devices face issues when displaying images from multiple devices simultaneously, requiring manual adjustments for image proportion and often resulting in black borders when connected with mobile devices, leading to low screen usage and unclear image content.
Innovation Solution
A display device with a processing circuit that detects black borders in incoming images, removes them, adjusts the image size to match the screen, calculates the blank area, and requests additional images to fill the screen without borders, ensuring seamless multi-device image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display device coordinates with mobile devices, then the image can be displayed on the screen, but black borders appear resulting in low screen usage rate
Solution Approach 1:
The processing circuit performs preliminary detection to identify black border areas in the incoming image before display. By detecting and removing black borders in advance, the system prepares the image for optimal screen utilization, ensuring that the full display area is used effectively when coordinating with mobile devices.
Solution Approach 2:
The system changes the parameters of the displayed image by removing black border areas and adjusting the image size. This parameter modification allows the image content to expand and fill the screen more completely, transforming the display from a constrained state with black borders to an optimized state that maximizes screen usage rate while maintaining compatibility with mobile devices.
2Adaptability or versatility
If the user wants to adjust proportion of image, then the image proportion can be customized, but manual setting is required which reduces ease of operation
Solution Approach 1:
The processing circuit performs self-service by automatically detecting black border areas and removing them without user intervention. The system also automatically adjusts the image size and proportion to optimize screen usage. This automated image processing eliminates the need for manual OSD settings, making the display device adaptable to different image formats while maintaining ease of operation.
3Area of stationary object
If black border area is removed and image size is adjusted, then screen usage rate increases, but additional processing operations are required which increases device complexity
Solution Approach 1:
The patent merges multiple image processing operations into a single integrated processing circuit. The detection of black borders, removal of black border areas, and adjustment of image size are combined into one unified processing unit. This consolidation achieves high screen usage rate while minimizing the increase in device complexity by performing multiple functions within a single circuit rather than requiring separate components for each operation.

AI summary
An image processing method applied to a display device having a processing circuit and a screen and includes: receiving a first image from one of a plurality of electronic devices; detecting whether the first image has a black border area; and if the first image has the black border area, performing a first display operation, wherein performing the first display operation includes: removing the black border area of the first image, to generate a second image; adjusting the size of the second image according to the size of a display area of the screen; calculating a first blank area of the screen based on the adjusted second image; requesting a third image from another one of the electronic devices according to the size of the first blank area; and filling the display area of the screen with the adjusted second image and the third image.
