Symmetrical Pixel Structure for Mirror Display Signal Consistency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display devices face challenges in achieving high image quality and operational performance, particularly in maintaining consistent image signal processing algorithms between normal and mirror displays due to asymmetrical pixel structures, which can lead to sharp edges and abnormal processing issues.
Innovation Solution
A pixel structure with alternately arranged first sub-pixel columns of two colors and second sub-pixel columns of a single color, where the number of first sub-pixel columns is one larger than the second, creating a symmetrical arrangement that allows for the same image signal processing algorithm to be used in both normal and mirror displays, along with a driving method that outputs data signals in reverse order during mirror display to maintain consistency.

Engineering Contradiction Analysis
1Device complexity
If an asymmetrical pixel structure is used, then device complexity is reduced, but image signal processing becomes abnormal and sharp edges appear during mirror display
Solution Approach 1:
The patent applies asymmetry principle by designing a pixel structure where the number of first sub-pixel columns is one larger than the number of second sub-pixel columns, creating a specific asymmetrical arrangement (e.g., 5 first columns and 4 second columns). This controlled asymmetry enables the pixel structure to adapt to both normal and mirror display modes, ensuring consistent image signal processing algorithms while avoiding abnormal processing and sharp edges during mirror display.
2Reliability
If a symmetrical pixel structure is used, then image signal processing consistency between normal and mirror displays is achieved, but device complexity increases
Solution Approach 1:
The patent applies local quality principle by making different parts of the pixel structure have different properties. Specifically, the first sub-pixel columns contain sub-pixels of two colors while the second sub-pixel columns contain sub-pixels of a single color. This local differentiation allows the overall structure to achieve the required symmetry for consistent image signal processing while maintaining manageable complexity through localized variations rather than uniform complexity throughout.
3Ease of operation
If data signal output order is not adjusted for mirror display, then operation simplicity is maintained, but sharp edges and abnormal processing occur
Solution Approach 1:
The patent applies inversion principle by reversing the data signal output order when mirror display is activated. Instead of outputting data signals in the conventional order (from first column to last column), the system outputs them in reverse order (from last column to first column). This inversion compensates for the mirror effect, ensuring that the displayed image maintains correct orientation and avoids sharp edges or abnormal processing artifacts during mirror display mode.

AI summary
Disclosed are a pixel structure, a display panel and a driving method thereof, the pixel structure comprising a plurality of alternately arranged first sub-pixel columns and second sub-pixel columns. The first sub-pixel columns comprise sub-pixels of two colors, the second sub-pixel columns are sub-pixel columns of single color, and the number of the first sub-pixel columns is one larger than that of the second sub-pixel columns. The first sub-pixel columns are one column more than the second sub-pixel columns, such that the whole pixel arrangement is a symmetrical arrangement.Therefore, when in mirror display, an image signal processing algorithm consistent with that in normal display can still be maintained.
