Symmetrical Flip Pixel Arrangement for Bidirectional Scanning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid crystal display panels face challenges in efficiently performing forward and reverse scanning without data signal processing, leading to image distortion due to incompatible data signals when the scanning direction is reversed.
Innovation Solution
The display panel is divided into two symmetrical flip pixel areas, with sub-pixels arranged in a one-to-one correspondence with data lines, allowing for axial symmetry and seamless switching between forward and reverse scanning modes without data signal processing, using a driving method that determines the current scan mode and operates accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If reverse scanning is implemented in traditional display panels, then the scanning direction can be reversed, but data signal processing becomes time-consuming and complex
Solution Approach 1:
The display panel is divided into a first area and a second area along the data line direction, with each area containing pixels that have identical sub-pixel arrangements. This segmentation allows independent control of data signals for each area, enabling reverse scanning in the second area while maintaining forward scanning in the first area, thus avoiding global data signal reprocessing
Solution Approach 2:
The patent employs asymmetric pixel arrangements where the first area uses a conventional pixel layout while the second area uses a mirror-symmetric pixel layout. This asymmetric design allows the display panel to adapt to different scanning directions without requiring complex data signal processing, as each area's pixel arrangement is optimized for its specific scanning direction

AI summary
A display panel, a driving method and a display device are disclosed. The display panel is divided into a first area and a second area arranged along a data line direction. Multiple sub-pixels corresponding to a same row of scan line are connected to data lines in one-to-one correspondence. In the first area and second area, each column of sub-pixels is arranged between two adjacent data lines, where the same column of sub-pixels includes multiple sub-pixel groups, each of which includes at least one sub-pixel. Among two adjacent data lines, one data line is connected with the sub-pixels in the odd groups, and the other is connected with the sub-pixels in the even groups. The sub-pixel groups in the first area and the corresponding sub-pixel groups in the second area are axially symmetrical with respect to a boundary line between the first area and the second area.
