Array Substrate Layout for HSR Without Dual-Gate Color Crosstalk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face challenges in implementing High Super Resolution (HSR) technology in dual-gate pixel driving structures due to color crosstalk issues, particularly in dual-gate pixel driving structures where one data line controls two columns of sub-pixels, leading to incorrect color display.
Innovation Solution
The array substrate design includes a pixel array with overlapping charging times for groups of sub-pixels, where each group is connected to two adjacent gate lines, and the charging times of these groups are staggered to ensure that sub-pixels connected to the same data line share the same color, thereby alleviating color crosstalk and enabling HSR technology in dual-gate pixel driving structures.

1Productivity
If a same data line is connected with sub-pixels of different colors to increase charging efficiency, then charging efficiency is improved, but color crosstalk occurs causing display quality degradation
Solution Approach 1:
The patent segments the data line connections by color channels. Specifically, even-numbered data lines (D0, D2, D4, D6) are connected only to blue sub-pixels, while odd-numbered data lines (D1, D3, D5, D7) are connected only to green and red sub-pixels. This segmentation prevents a single data line from controlling sub-pixels of different colors, thereby eliminating color crosstalk while maintaining efficient charging through the dual-gate pixel structure.
2Manufacturing precision
If HSR technology is implemented in dual-gate pixel driving structures to enhance resolution, then resolution is improved, but color crosstalk issues arise due to data lines controlling sub-pixels of different colors
Solution Approach 1:
The patent applies local quality by assigning different connection patterns to different data lines based on their indices. Even-indexed data lines are dedicated to blue sub-pixels, while odd-indexed data lines serve green and red sub-pixels. This localized differentiation in connection quality ensures that each data line maintains pure color control, enabling HSR technology to achieve enhanced resolution without the color crosstalk that would otherwise occur in dual-gate pixel structures.

AI summary
An array substrate, a driving method thereof, and a display device. In the array substrate, rows of sub-pixels include groups of sub-pixels, each group of sub-pixels includes part of the rows of sub-pixels, and charging times of the part of the rows of sub-pixels are overlapped. A charging time of the second part of the plurality of rows of sub-pixels is longer than a charging time of the first part of the plurality of rows of sub-pixels. During a first time period, a same data signal is written into the first part of the plurality of rows of sub-pixels and the second part of the plurality of rows of sub-pixels, and during a second time period, a data signal written into the second part of the plurality of rows of sub-pixels is at least partially the same as the data signal written during the first time period.
