Image Display Device Sensor Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image display devices like liquid crystal and plasma displays, the installation of brightness or color sensors on the screen leads to regions being hidden from view, and external sensors can cast shadows, interfering with the display during measurement.
Innovation Solution
A sensor position detecting unit identifies the sensor's position on the screen, and an image processing unit displays the hidden region at another location, allowing the image to be visible, with optional pointer detection to adjust the display accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an image sensor is installed on the screen display portion, then color calibration measurement can be performed, but the region where the sensor is installed becomes hidden from view
Solution Approach 1:
The patent displays a copy of the image that would normally be shown at the sensor position at a different location on the screen. The image processing unit receives image data, identifies the sensor position, and renders a representative image at an alternative display location, allowing users to view what would otherwise be blocked by the sensor during measurement operations
Solution Approach 2:
The patent resolves the spatial conflict by transitioning from a two-dimensional screen plane to a three-dimensional solution space. Instead of trying to fit the sensor and display simultaneously in the same plane, the system creates a virtual representation of the blocked region and displays it at a different spatial location on the screen, effectively adding a dimensional layer to resolve the obstruction
2Adaptability or versatility
If a brightness sensor or color sensor is installed on the screen, then measurement function is provided, but a partial region of the screen is not visible to the user
Solution Approach 1:
The system creates a visual copy of the blocked region's content and displays it at an alternative location. The image processing unit generates a representative image of what would be shown at the sensor position and renders it at a different screen location, allowing users to access visual information that would otherwise be inaccessible due to the sensor's physical presence
Solution Approach 2:
The patent introduces an intermediary mechanism - the image processing unit - that mediates between the sensor's measurement function and the user's viewing requirement. This intermediary detects the sensor position, processes the image data, and presents an alternative visualization that satisfies both the measurement capability and the visibility requirement
3Measurement precision
If an external sensor is used for measurement, then the sensor can be positioned externally, but the sensor casts a shadow on the screen interfering with display
Solution Approach 1:
The patent converts the harmful shadow effect into a beneficial positioning indicator. By detecting the shadow cast by the external sensor, the system identifies the sensor's position and uses this information to determine where to display the alternative image. The shadow, which was originally a harmful interference, becomes a useful signal for positioning the visual correction
Solution Approach 2:
The system displays a copy of the image data at a location different from where the external sensor is positioned. The image processing unit receives image data, determines the sensor position through shadow detection or other means, and renders the image at an alternative location that does not interfere with the measurement function
