AI Technical Summary

Technical Problem

Current display panels experience display defects such as light and dark stripes or screen splitting due to signal load differences caused by overlapping wiring connected to multi-multiplexing circuits, particularly in wearable products like watches, especially when displaying low grayscale images.

Method used

A display panel design with a base, subpixels, data lines, multi-multiplexing circuits, multiplexed data lines, and N multiplexing control lines, where the orthographic projection of multiplexed data lines and control lines are either partially overlapping or non-overlapping, reducing signal load differences by optimizing their layout.

Benefits of technology

The optimized layout significantly reduces display malfunctions by minimizing signal load differences, improving image quality in wearable devices and reducing bezel size.

Abstract

The display panel comprises a base, a plurality of subpixels, a plurality of data lines, a plurality of multi-multiplexing circuits, a plurality of multiplexed data lines, and N multiplexing control lines. The plurality of multi-multiplexing circuits, the plurality of multiplexed data lines, and the N multiplexing control lines are located in a first bezel region on at least one side of the display area. N is equal to 2n+1, and n is an integer greater than 0. At least one multi-multiplexing circuit is electrically connected to the N multiplexing control lines, one multiplexed data line, and the plurality of data lines, and is configured to provide the plurality of data lines with data signals transmitted by the multiplexed data lines under the control of the N multiplexing control lines. There is an overlapping portion in the orthogonal projection of each multiplexed data line and at least n multiplexing control lines on the base, or there is no overlapping portion in the orthogonal projection of the plurality of multiplexed data lines and N multiplexing control lines on the base.
