Solution Overview

Problem

Conventional display apparatuses rely on bulky power cables, which hinder the thin and bezel-less design goal by adding thickness and visual clutter, compromising user immersion and aesthetic appeal.

Innovation Solution

A display apparatus that utilizes a transparent electrode panel to receive power, eliminating the need for traditional power cables and maintaining transparency and thinness while ensuring efficient power transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If a traditional power cable is used to supply power to the display apparatus, then power transmission is ensured, but the thickness and visual clutter increase, compromising the thin design and user immersion

Engineering Contradiction:
ImprovethicknessVSAvoidpower supply reliability
Core Design Contradiction:
Length of moving objectVSReliability

Solution Approach 1:

The patent extracts the power transmission function from the traditional power cable and relocates it to the electrode panel. The power cable is completely removed from the system, and its power supply function is integrated into the transparent electrode panel through conductive patterns that can transmit power wirelessly or through minimal contact points, thus eliminating the bulky cable while maintaining power supply reliability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The electrode panel is given multiple functions: it serves both as the display electrode structure and as the power transmission medium. The conductive patterns on the transparent substrate enable the panel to simultaneously perform its electrostatic display function and power transmission function, eliminating the need for separate power cables and reducing overall device thickness

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

2Illumination intensity

If a traditional power cable is connected to the rear side of the display apparatus, then power supply is ensured, but visual clutter and aesthetic appeal are compromised

Engineering Contradiction:
Improvevisual clarityVSAvoidpower supply stability
Core Design Contradiction:
Illumination intensityVSReliability

Solution Approach 1:

The power cable is extracted from the rear connection system and its function is integrated into the electrode panel itself. This removes the visual clutter of cables connected to the rear side while maintaining stable power supply through the transparent conductive patterns embedded in the panel structure

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The transparent electrode panel with conductive patterns provides visual clarity by being invisible or minimally visible when in use. The conductive patterns are designed to be transparent or translucent, allowing light to pass through while still transmitting power, thus maintaining aesthetic appeal and visual clarity without compromising power supply stability

Inventive Principle:
Principle #32Color changes

3Length of moving object

If the display apparatus is designed with thin thickness and short bezel to increase image immersion, then aesthetic appeal and user immersion are improved, but space for traditional power cable connection is reduced

Engineering Contradiction:
ImprovethicknessVSAvoidpower connection structure
Core Design Contradiction:
Length of moving objectVSDevice complexity

Solution Approach 1:

The electrode panel serves dual purposes as both the display electrode and the power transmission medium. The conductive patterns on the transparent substrate enable power transmission without requiring separate cable connection spaces, allowing the device to maintain thin thickness and short bezel while simplifying the power connection structure

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

Solution Approach 2:

The power transmission function is moved from a three-dimensional cable structure to a two-dimensional planar pattern on the electrode panel. This dimensional change eliminates the need for cable routing and connection spaces, enabling thinner device design while reducing structural complexity

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