Pixel Structure Electrode Segmentation for Display Response

Solution Overview

Problem

Manufacturers face challenges in creating portable eSports products with high performance, low energy consumption, and high display quality, particularly in maintaining high transmittance while increasing response speeds in display panels used in in-planes switching and fringe field switching modes.

Innovation Solution

A pixel structure is designed with a specific electrode configuration, including a main portion, branch portions, auxiliary portions, and a light-shielding pattern layer, which enhances aperture ratio and storage capacitance, allowing for improved liquid crystal molecule recoverability and reduced response time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the electrode structure is simplified to reduce manufacturing complexity, then device complexity is reduced, but aperture ratio and storage capacitance decrease

Engineering Contradiction:

Improveelectrode structure complexityVSAvoidaperture ratio

Core Design Contradiction:

Device complexityVSArea of moving object

Solution Approach 1:

The electrode structure is divided into multiple branch portions (first branch portions and second branch portions) that extend from the main portion in alternating directions. This segmentation increases the total electrode area and aperture ratio while maintaining a systematic pattern that controls manufacturing complexity through repetitive structures.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The electrode structure transitions from a simple single-direction extension to a multi-dimensional arrangement with branch portions extending in alternating directions (first direction and second direction perpendicular to first direction). This dimensional expansion increases aperture ratio without proportionally increasing manufacturing complexity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A pixel structure including an active device, a first electrode and a second electrode is provided. The first electrode includes a main portion, first branch portions, a first auxiliary portion and a second auxiliary portion. The second electrode includes second branch portions and a peripheral portion. The main portion extends in a first direction. The first branch portions and the second branch portions cross with the main portion and are arranged alternately in the first direction. Each first branch portion has a first end and a second end located on two opposite sides of the main portion respectively. The first auxiliary portion is connected to the first ends of the first branch portions. The second auxiliary portion is connected to the second ends of the first branch portions. The first auxiliary portion and the second auxiliary portion of the first electrode overlap the peripheral portion of the second electrode.
