Display Signal Rearrangement for Inverted Strip Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Strip-shaped displays used upside down display inverted images due to invalid line parts not being displayed correctly, leading to viewer confusion and limited applicability.
Innovation Solution
A display control method that rearranges input image data to separate valid and invalid line parts, generates specific control signals for frame display and line scanning, and outputs these signals to correct the display orientation without altering the display panel's physical position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If strip-shaped display is used upside down, then installation flexibility is improved, but image orientation becomes inverted and display quality deteriorates
Solution Approach 1:
The patent applies preliminary action by preprocessing the input image data before it reaches the display panel. The image data is rearranged in advance to compensate for the inverted display orientation, so that when the display panel is used upside down, the image appears correctly oriented to the viewer. This involves reordering the pixel data and adjusting the scan timing accordingly.
Solution Approach 2:
The patent changes key parameters of the image data including the scanning direction, valid line range, and timing control signals. By modifying these parameters dynamically based on the display panel's orientation state, the system maintains correct image orientation regardless of whether the display is installed upright or inverted.
2Area of stationary object
If invalid line parts are displayed, then display coverage is improved, but image quality and viewer understanding deteriorate
Solution Approach 1:
The patent extracts and removes the invalid line parts from the image data that corresponds to the non-displaying regions of the strip-shaped display panel. By identifying which lines are valid for display and which are invalid, the system selectively processes only the relevant portions of the image data, preventing meaningless or distorted content from being displayed in the invalid regions.
Solution Approach 2:
The patent applies different processing quality to different regions of the image data. Valid line parts receive full processing and display quality, while invalid line parts are either removed, blanked, or marked as non-displaying. This ensures that the display region maintains high image quality while the non-display region does not waste resources on unnecessary content.

AI summary
The present disclosure provides a display control method, a display control device, and a display device. The display control method includes performing a first display mode using an input image data. Performing the first display mode includes: rearranging the input image data to obtain a rearranged image data, the input image data including a valid line part for actual display on a display panel and an invalid line part for non-actual display on the display panel, and the rearranged image data including a rearranged valid line part and a rearranged invalid line part corresponding to the valid line part and the invalid line part, respectively; generating a first image display control signal and a first delay control signal corresponding to the rearranged image data; and outputting the rearranged image data, the first image display control signal, and the first delay control signal.
