Solution Overview

Problem

Current LCD technologies face challenges in achieving an ultra narrow frame or frame-free design due to the occupied width of gate driving circuits integrated in the peripheral region, hindering the realization of these designs.

Innovation Solution

A display panel configuration with a first and second substrate, a light shielding pattern between them, and first pixel units located in the peripheral region, where the driving circuit is electrically connected to all first pixel units and a printed circuit board, allowing the peripheral region to display images and enabling an ultra narrow frame or frame-free design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If gate driving circuits are integrated in the peripheral region of the display panel, then the driving function is achieved, but the frame width increases and ultra narrow frame design is hindered

Engineering Contradiction:
Improveframe widthVSAvoidcircuit integration complexity
Core Design Contradiction:
Length of moving objectVSDevice complexity

Solution Approach 1:

The patent moves the pixel units from the traditional planar display region into the peripheral region along the edge of the display panel, utilizing the third dimension (edge/perimeter space) rather than only the two-dimensional central area. This dimensional shift allows the pixel units to be arranged in a linear fashion along the periphery, enabling ultra-narrow frame design while maintaining driving circuit integration.

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

Solution Approach 2:

The display panel is segmented into a central display region and peripheral pixel units, with the pixel units divided into first pixel units (in the peripheral region) and second pixel units (in the display region). This segmentation allows independent optimization of different regions, with the peripheral region dedicated to ultra-narrow frame pixel units and the central region maintaining traditional display functions.

Inventive Principle:
Principle #1Segmentation

2Length of moving object

If pixel units are arranged in the peripheral region, then ultra narrow frame design is achieved, but the display area is reduced

Engineering Contradiction:
Improveframe widthVSAvoiddisplay area
Core Design Contradiction:
Length of moving objectVSArea of stationary object

Solution Approach 1:

The patent utilizes the peripheral edge dimension of the display panel to arrange pixel units, converting what would be wasted edge space into functional display area. By placing pixel units along the periphery rather than sacrificing central display area, the design achieves ultra-narrow frames without proportionally reducing overall display area.

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

Solution Approach 2:

The peripheral region serves dual functions: it provides the ultra-narrow frame structure and simultaneously functions as an active display area through the first pixel units. This multi-functionality allows the same spatial region to contribute both to frame reduction and to overall display area, eliminating the trade-off between frame width and display area.

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

3Shape

If the peripheral region is used for pixel units, then frame-free design is enabled, but the driving circuit layout becomes more complex

Engineering Contradiction:
Improveframe structureVSAvoiddriving circuit layout
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The patent merges the driving circuit integration with the peripheral pixel unit arrangement, where the driving circuits are co-located with the first pixel units in the peripheral region. This combining of driving functions with the ultra-narrow frame pixel units simplifies the overall layout by eliminating separate driving circuit regions that would otherwise increase frame width.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The driving circuits are arranged in the peripheral dimension along with the first pixel units, utilizing the edge space of the display panel. This peripheral arrangement in the third dimension (edge region) allows both pixel units and driving circuits to coexist without increasing the central display area or frame width, enabling frame-free design.

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