Color Filter Sub-Pixel Segmentation for 3D Display Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The manufacturing of color filters for 3D display devices is challenging due to the need for high resolution and precise alignment of sub-pixels, which increases the difficulty and cost of producing smaller sub-pixels with distinct colors.
Innovation Solution
A color filter design featuring a substrate with intersecting black matrix strips forming mesh regions, where each sub-pixel is divided into an even number of sub-sub-pixels of the same color, allowing for easier manufacturing and alignment, with a method involving the formation of red, green, and blue resists in these regions to maintain high resolution without increasing manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sub-pixels are made smaller to increase resolution, then display resolution is improved, but manufacturing precision requirements increase
Solution Approach 1:
Each sub-pixel is divided into an even number of sub-sub-pixels of the same color (e.g., two red sub-sub-pixels, two green sub-sub-pixels, two blue sub-sub-pixels). This segmentation allows the color filter to be manufactured with relaxed precision requirements while maintaining high display resolution, as the sub-sub-pixels can be formed in a single step with less stringent mask alignment tolerances.
2Measurement precision
If sub-pixels are made smaller to increase resolution, then display resolution is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The color filter manufacturing process merges the formation of multiple color resists into a single step. By dividing each sub-pixel into sub-sub-pixels of the same color and forming all color resists simultaneously, the manufacturing process is simplified, reducing both complexity and cost while maintaining high resolution.
3Ease of manufacture
If traditional color filter manufacturing is used, then manufacturing process is simple, but alignment precision of sub-pixels deteriorates
Solution Approach 1:
By segmenting each sub-pixel into multiple sub-sub-pixels of the same color, the invention enables a manufacturing process that is both simple and precise. The segmentation allows for single-step formation of color resists with reduced alignment requirements, simultaneously improving ease of manufacture and alignment precision.

AI summary
A color filter and a manufacturing method, a display panel, and a display device and a driving method are provided. The color filter includes a plurality of color resists which include red resists (R), green resists (G) and blue resists (B); and the color filter includes a plurality of pixel regions arranged in a matrix, each pixel region comprises a red sub-pixel region comprising an even number of red sub-sub-pixel regions, a green sub-pixel region including an even number of green sub-sub-pixel regions, a blue sub-pixel region including an even number of blue sub-sub-pixel regions, each red sub-sub-pixel region is provided with a red resist, each green sub-sub-pixel region is provided with a green resist, and each blue sub-sub-pixel region is provided with a blue resist. The manufacturing precision and alignment accuracy of a mask for this color filter is lower than a current technology and reduce the manufacturing difficulty.
