Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional pixel arrangement is used for high-resolution display, then image accuracy and detail are improved, but temperature of screen and display elements increases excessively
Solution Approach 1:
The patent merges adjacent sub-pixels from multiple pixel units to form shared pixels. Specifically, sub-pixels are grouped such that sub-pixel (1,2) is shared between pixel unit (1,1) and pixel unit (1,2), and sub-pixel (2,1) is shared between pixel unit (1,1) and pixel unit (2,1). This merging reduces the total number of independent pixel units that need to be driven, thereby reducing overall power consumption and temperature while maintaining high-resolution display capability.
2Quantity of substance
If data transmission bandwidth is increased for high-resolution screens, then more information is displayed, but temperature of screen and chip on film increases
Solution Approach 1:
By merging sub-pixels across pixel unit boundaries, the patent reduces the total number of pixel units that require independent data transmission. This consolidation decreases data transmission bandwidth requirements and reduces the thermal load on both the screen and chip on film, while still achieving high-resolution display through the shared pixel structure.
3Speed
If frequency of data lines is increased for high-resolution display, then data transmission capacity is improved, but temperature of screen and COF rises above acceptable levels
Solution Approach 1:
The patent reduces data transmission frequency requirements by merging sub-pixels into shared pixels across pixel unit boundaries. This consolidation decreases the number of independent pixel units that require data transmission, thereby lowering the frequency of data lines and reducing thermal load on the screen and COF to acceptable levels while maintaining high-resolution display capability.
4Adaptability or versatility
If pixel multiplexing is implemented for compatibility with both high and low-resolution displays, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent segments the display into repeating pixel groups, where each group follows a standardized sub-pixel sharing pattern. This segmentation approach makes the complex pixel multiplexing scheme more manageable and implementable by breaking it down into reusable modular units that can be tiled across the entire display, thereby reducing overall device complexity while maintaining compatibility with both high and low-resolution displays.

AI summary
Embodiments of the present disclosure provide a pixel arrangement structure, a display panel, and a display device. The pixel arrangement structure includes at least one repeating pixel group, wherein each of the at least one repeating pixel group includes a first pixel unit, a second pixel unit, a third pixel unit, and a fourth pixel unit. Two sub-pixels of the first pixel unit are adjacent to two sub-pixels of the second pixel unit, and two sub-pixels of the third pixel unit are adjacent to two sub-pixels of the fourth pixel unit, thereby achieving pixel multiplexing.
