Transparent Display Pixel Layout With White Sub-Pixel Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transparent display devices face challenges in ensuring a sufficient transmissive area and clear visibility of objects behind the display panel, leading to image clumping and degradation of image quality, particularly when emitting white or gray light.
Innovation Solution
The display device is designed with a configuration where transmissive areas of adjacent pixels are adjacent to each other, incorporating a fourth sub-pixel that emits white light to maintain an interval between other colored sub-pixels, improving the see-through characteristic and reducing image clumping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If transmissive areas of adjacent pixels are made adjacent to each other to improve see-through characteristic, then the transmissive area is improved, but image clumping occurs between adjacent pixels
Solution Approach 1:
The pixel structure is segmented into multiple sub-pixels (first, second, third, and fourth sub-pixels). The fourth sub-pixel is specifically positioned between the first sub-pixel of one pixel and the first sub-pixel of the adjacent pixel, creating a segmentation that prevents direct adjacency of corresponding sub-pixels across pixel boundaries, thereby reducing image clumping while maintaining transmissive area.
Solution Approach 2:
Different regions of the pixel structure are assigned different functions. The fourth sub-pixel is strategically placed at a specific location (adjacent to one side of the first, second, and third sub-pixels) to serve as a spacer that prevents image clumping, while other sub-pixels are optimized for light emission. This local differentiation resolves the contradiction between transmissive area and image quality.
2Productivity
If sub-pixels are disposed adjacent to each other to improve resolution, then the display density is improved, but image clumping and vertical line degradation occur
Solution Approach 1:
The display is segmented into multiple sub-pixels within each pixel structure. By dividing the pixel into four sub-pixels and strategically positioning them, the invention achieves high display density while preventing the image clumping that would result from simple adjacency of all sub-pixels.
Solution Approach 2:
The fourth sub-pixel acts as an intermediary element between the first sub-pixels of adjacent pixels. This intermediary sub-pixel maintains proper spacing and prevents direct contact between corresponding sub-pixels of neighboring pixels, thereby preventing vertical line degradation and image clumping while preserving high display density.
3Illumination intensity
If white light is emitted to improve brightness, then the illumination intensity is improved, but image clumping and vertical line representation degrade
Solution Approach 1:
The white light emission function is segmented across multiple sub-pixels. The fourth sub-pixel is specifically configured to emit white light, while other sub-pixels emit colored light. This segmentation allows white light emission to be achieved without causing image clumping, as the white-light-emitting sub-pixel is strategically positioned to maintain proper spacing with adjacent pixels.
