Solution Overview

Problem

Conventional liquid crystal display (LCD) devices have a wide bezel area at the bottom, which is aesthetically undesirable and increases the overall size, due to the need for mounting the data driver and separate connection members, affecting the visual appeal and design.

Innovation Solution

An auxiliary panel made of the same material as the upper substrate is positioned to cover the non-display area and data driver, minimizing the bezel area by integrating the data driver connections and forming an auxiliary display area for additional information, while maintaining a uniform visual appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the data driver and connection members are mounted separately on the display panel, then the electrical connection is reliable, but the bezel area increases and aesthetic appeal deteriorates

Engineering Contradiction:
Improveelectrical connection reliabilityVSAvoidbezel area
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent merges the data driver and connection members into a single integrated component. The connection member includes both the connection terminal for electrical connection and the data driver circuitry in one unified structure, eliminating the need for separate mounting and reducing the bezel area while maintaining reliable electrical connections.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connection member serves multiple functions simultaneously: it provides electrical connection between the display panel and external devices, houses the data driver circuitry, and acts as a structural component of the display assembly. This multi-functionality reduces the number of separate components needed and minimizes the overall bezel area.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Shape

If the bezel area is reduced to improve aesthetics, then the visual appeal increases, but the space for mounting data driver and connection members becomes insufficient

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidmounting space availability
Core Design Contradiction:
ShapeVSEase of manufacture

Solution Approach 1:

The patent utilizes the vertical dimension by extending the connection member downward from the front surface of the display panel. This allows the data driver and connection terminals to be positioned in three-dimensional space rather than constrained to a two-dimensional plane, enabling reduced bezel area while maintaining adequate space for component mounting and electrical connections.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If separate connection members are used for data transmission, then the electrical connection is stable, but the overall device size increases

Engineering Contradiction:
Improveconnection stabilityVSAvoiddevice size
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The patent combines the connection member and data driver into a single integrated component, eliminating the need for separate mounting of these elements. This integration reduces the overall device volume by eliminating gaps and redundant structural elements between separate components while maintaining stable electrical connections through the integrated design.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

In various embodiments, a display panel is provided. The display panel includes a first substrate (TFS), on which a display area (AA) and a non-display area (NA) are defined, and an auxiliary panel (ADS) disposed over the non-display area (NA) of the first substrate (TFS) and a portion (PA) laterally protruding out of an edge of the non-display area (NA) of the first substrate (TFS). The auxiliary panel (ADS) includes a connection region for electrical connection, the connection region being arranged in the portion (PA) laterally protruding out of an edge of the non-display area (NA) of the first substrate (TFS), the connection region including at least one connection pad (APD1).
