Pixel Structure With Periodic Monochrome and White Subpixels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pixel arrangements requiring a large number of subpixels to achieve certain resolution lead to increased backlight power consumption, resulting in higher product costs to maintain brightness.
Innovation Solution
A pixel structure with two rows of subpixels in each pixel unit, including a monochrome and a white subpixel, where monochrome subpixels are arranged periodically to mix into white light, reducing the number of RGB subpixels needed while enhancing image resolution and brightness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a large number of subpixels are arranged in conventional RGB configuration to achieve certain resolution, then the resolution is improved, but the light transmittance of the panel deteriorates
Solution Approach 1:
The patent merges the white subpixel with the RGB subpixel structure, creating a unified pixel unit where white and colored subpixels work together. This integration allows the white subpixel to compensate for the reduced light transmittance caused by the increased number of subpixels needed for high resolution, thereby resolving the contradiction between achieving high resolution and maintaining light transmittance
2Illumination intensity
If the number of subpixels is increased to maintain required brightness in conventional arrangement, then the brightness is improved, but the product cost increases
Solution Approach 1:
The white subpixel serves multiple functions: it provides brightness enhancement, compensates for light loss from increased subpixel density, and reduces the need for high backlight power. This multi-functionality allows the system to maintain brightness at lower cost by utilizing the white subpixel's ability to emit broad-spectrum light that contributes to overall display brightness without requiring proportional increases in backlight power

Function Achieved in This Case
This arrangement achieves comparable resolution to conventional RGB pixel structures with fewer subpixels, improving image resolving power and display brightness at a lower cost by reducing backlight power requirements.
Implementation Method 1
monochromatic light beams emitted by the first monochrome subpixel, the second monochrome subpixel and the third monochrome subpixel are capable of being mixed into white light
