Data Divider Selector Spacing for Display Peripheral Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As display devices become more high-resolution, the increased number of driving circuits and wires reduces available space in the peripheral area, making it challenging to efficiently arrange components such as data dividers and drivers.
Innovation Solution
The display device incorporates a data divider with strategically arranged first and second selectors, where the distance between adjacent second selectors is shorter than that of first selectors, allowing for more compact arrangement and efficient use of space in the peripheral area, enabling time-division driving of data signals.

Engineering Contradiction Analysis
1Measurement precision
If the number of driving circuits and wires is increased to achieve high-resolution display, then the display resolution is improved, but the available space in the peripheral area is reduced
Solution Approach 1:
The data writing time is divided into multiple time slots, and the data driver outputs data signals through multiple channels in a time-division manner. This segmentation of time and channels allows high-resolution data transmission while reducing the physical space required for wiring and driving circuits in the peripheral area.
Solution Approach 2:
The data driver periodically outputs data signals through different channels in alternating time slots. By using periodic time-division multiplexing, the system achieves high-resolution display capability while minimizing the spatial requirements for driving circuits and wires in the peripheral region.
2Area of stationary object
If the distance between adjacent selectors in the data divider is reduced to save space, then the peripheral area space is improved, but the signal integrity may be compromised
Solution Approach 1:
The data divider employs different selector configurations for different regions: first selectors are positioned at regular intervals for standard signal routing, while second selectors are strategically placed at shorter intervals in specific areas to maintain signal integrity where needed. This localized adaptation of selector spacing ensures both space efficiency and signal quality.
Solution Approach 2:
The data divider acts as an intermediary component between the data driver and the display panel, with selectors that mediate the data signal distribution. By carefully designing the spacing and arrangement of these intermediary selectors, the system achieves compact layout while preserving signal integrity through proper signal routing and timing control.

AI summary
A display device includes a substrate including a display area and a peripheral area, a pixel area, a data driver, a data divider, and coupling lines that couple the data driver to the data divider. The pixel area includes first pixel lines in a first area of the display area and coupled to first area data lines, and second pixel lines disposed in a second area of the display area and coupled to second area data lines. The data driver outputs data signals corresponding to the first and second pixel lines. The data divider includes first selectors that transfer the data signals corresponding to the first pixel lines to the first area data lines, and second selectors that transfer the data signals corresponding to the second pixel lines to the second area data lines. A distance between adjacent second selectors is shorter than a distance between adjacent first selectors.
