Array Substrate Data Line Sharing for Display Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels have high power consumption due to the large number of data lines required for each pixel point, which increases energy usage during operation.
Innovation Solution
The array substrate design includes multiple data lines and scan lines on a first substrate, where the length of sub-pixels in the extension direction of the data lines is less than their width in the extension direction of the scan lines, allowing sub-pixels to share data lines and reducing the number of data lines needed for each pixel point, thereby decreasing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If each sub-pixel is connected to an adjacent data line, then each pixel point can be displayed with three colors (red, green, blue), but the number of data lines increases significantly, resulting in high power consumption
Solution Approach 1:
Multiple sub-pixels of different colors (red, green, blue) share a common data line. Instead of providing separate data lines for each sub-pixel, the invention merges the data line connections so that one data line can control multiple sub-pixels, thereby reducing the total number of data lines and lowering power consumption while maintaining full-color display capability
Solution Approach 2:
A single data line is designed to serve multiple functions by controlling multiple sub-pixels of different colors. The data line becomes a universal control line that can drive red, green, and blue sub-pixels sequentially or simultaneously, reducing the need for dedicated data lines for each sub-pixel type
2Quantity of substance
If the length of sub-pixels in the extension direction of data lines is increased, then fewer data lines are needed, but the width of sub-pixels in the extension direction of scan lines must be reduced, affecting display quality
Solution Approach 1:
The invention changes the orientation and dimensional relationship of sub-pixels relative to data lines and scan lines. By making the length of sub-pixels in the data line extension direction less than their width in the scan line extension direction, it creates a new dimensional configuration that allows multiple sub-pixels to share data lines effectively without compromising display quality

AI summary
An array substrate and a display panel are provided according to embodiments, which include: a first substrate; multiple data lines and multiple scan lines located on a first side of the first substrate. The multiple data lines and multiple scan lines define a pixel array. The pixel array includes multiple sub-pixels. A length of each of the sub-pixels in an extension direction of the data lines is less than a width of each of the sub-pixels in an extension direction of the scan lines. The pixel array includes multiple first pixel groups and multiple second pixel groups arranged in a matrix form. A type of each of the sub-pixels included in the first pixel groups is different from a type of each of the sub-pixels in the second pixel groups. The first pixel groups and the second pixel groups are arranged alternately.
