Solution Overview
Problem
The increasing demand for high-resolution display products leads to higher power consumption, necessitating a solution to reduce power consumption in display devices.
Innovation Solution
A display substrate design with a diamond-like arrangement of subpixels and data lines, where subpixel driving circuits and light-emitting elements are alternately arranged to minimize the need for repeated data signal charging by the driving chip, thereby reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the resolution of the display product is increased, then the display quality is improved, but the power consumption increases
Solution Approach 1:
The display substrate is divided into multiple driving circuit columns, with each column independently driving light-emitting elements of the same color. This segmentation allows the driving chip to charge data signals once per column rather than repeatedly for each individual pixel, significantly reducing power consumption while maintaining high resolution display capabilities
Solution Approach 2:
The patent introduces a column-based driving architecture that adds a dimensional organization to the traditional row-by-row pixel driving method. By grouping pixels into columns and using shared data lines for same-color elements across columns, the system reduces the dimensionality of signal charging operations, thereby lowering power consumption
2Device complexity
If the data lines are coupled to subpixel driving circuits in a conventional manner, then the circuit design is simple, but the driving chip needs to repeatedly charge data signals increasing power consumption
Solution Approach 1:
Multiple subpixel driving circuits within the same driving circuit column share common data lines. This merging approach allows the driving chip to charge the data signal once for the entire column, and all driving circuits in that column utilize the charged signal, thereby reducing repeated charging operations and lowering power consumption while maintaining manageable circuit complexity
