Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When display devices with different pixel sizes are combined, the continuity of the image is hindered, and the appearance of the image differs from the original, due to differences in pixel size, leading to mismatched display details and discomfort in image connection.
Innovation Solution
A display control device equipped with a photodetection sensor that detects light from pixels of adjacent display devices with different pixel sizes and a display adjustor that determines the degree of enlargement or reduction of video signals based on the pixel size difference, ensuring consistent image display across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If display devices with different pixel sizes are combined to construct a multi-display system, then the adaptability of the display system to different installation places is improved, but the image continuity and appearance quality deteriorate due to differences in pixel size between devices
Solution Approach 1:
The patent applies parameter changes by detecting the actual pixel sizes of different display devices and adjusting the display parameters (enlargement/reduction degrees) of video signals accordingly. The photodetection sensor measures the pixel dimensions, and the control device calculates appropriate scaling factors to compensate for pixel size differences, thereby maintaining image continuity across devices with different specifications
Solution Approach 2:
The patent implements feedback through the photodetection sensor that continuously monitors the pixel sizes of display devices. The detected pixel size information is fed back to the control device, which then adjusts the video signal processing parameters in real-time to compensate for detected variations, ensuring consistent image quality across the multi-display system
2Adaptability or versatility
If display devices with different pixel sizes are combined, then the flexibility of system configuration is improved, but the display precision and image quality deteriorate due to mismatched pixel sizes
Solution Approach 1:
The control device changes display parameters by calculating and applying different enlargement or reduction degrees to video signals based on the detected pixel sizes of individual display devices. This parameter adjustment compensates for the inherent pixel size differences, maintaining precise and consistent image display across devices with varying specifications
Solution Approach 2:
The patent uses the photodetection sensor to create an accurate digital copy or model of the actual pixel sizes of display devices. This detected information is then used to generate appropriate scaling parameters that replicate the intended image appearance across all devices, ensuring display precision despite hardware variations

AI summary
A display control device includes: a photodetection sensor configured to detect light from pixels of display screens with both a first display device and a second display device with a pixel size different from that of the first display device in a display system in which a video signal is displayed on a plurality of display devices adjacent to each other as detection targets; and a display adjustor configured to determine a degree of enlargement or reduction of video signals displayed on the display devices on the basis of a difference between the pixel size of the first display device and the pixel size of the second display device based on a result of detection from the photodetection sensor.
