Pixel Array Sub-Pixel Groups for Dynamic Visual Resolution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display panels have fixed visual resolution, unable to meet varying requirements for low or high resolution depending on the application, as they are composed of fixed sub-pixel configurations.
Innovation Solution
A pixel array with sub-pixel groups arranged in a two-dimensional matrix, where each group consists of two or three sub-pixels of the same color, allowing independent control and staggering to achieve flexible visual resolutions, along with a driving method that calculates and adjusts brightness values for each sub-pixel group based on theoretical pixel units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed sub-pixel configuration (three or four sub-pixels per pixel) is used, then the manufacturing process is simple and the device structure is straightforward, but the visual resolution cannot be dynamically adjusted to meet varying requirements
Solution Approach 1:
The patent divides each physical pixel into multiple sub-pixel groups, where each group contains multiple actual sub-pixels of the same color (2-3 sub-pixels). These sub-pixel groups can be independently controlled to display different brightness levels, enabling the same physical pixel to represent multiple theoretical pixels. This segmentation allows dynamic adjustment of visual resolution without changing the physical structure, resolving the contradiction between adaptability and structural complexity.
2Measurement precision
If multiple actual sub-pixels of the same color are arranged closely in sub-pixel groups, then high visual resolution can be achieved by independent control, but the area occupied by each physical pixel increases
Solution Approach 1:
The patent merges multiple actual sub-pixels of the same color into compact sub-pixel groups within each physical pixel. By combining 2-3 sub-pixels of the same color into each group and arranging multiple such groups in a physical pixel, the design achieves high visual resolution through independent control of each sub-pixel while maintaining a compact physical footprint. The merging of same-color sub-pixels optimizes space utilization.
3Ease of operation
If all actual sub-pixels in a sub-pixel group are driven independently, then flexible brightness control and high visual resolution are achieved, but the driving circuit complexity and signal processing requirements increase
Solution Approach 1:
The patent designs the pixel array so that each physical pixel contains multiple sub-pixel groups that can function in multiple modes: they can be controlled independently for high visual resolution, or they can be driven together as a unified group for standard display modes. This multi-functionality allows the same hardware structure to support both simple and complex operating modes, reducing the need for entirely separate driving circuits for different resolution requirements.
