Solution Overview

Problem

Tiled displays formed by connecting LCDs suffer from discrete areas where bezels intersect, leading to image discontinuity and installation difficulties due to the need for additional components and separate image processing.

Innovation Solution

A bezelless LCD apparatus is created using panels with exposed liquid crystal pixels on multiple sides, connected by a backlight unit with LEDs, and integrated circuits for driving the pixels, allowing seamless image display without bezels and facilitating easy installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional LCDs with bezels are connected to form a tiled display, then the display can be assembled with standard components, but discrete areas occur at bezel intersections causing image discontinuity

Engineering Contradiction:
Improveimage continuityVSAvoidneed for additional components
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The bezel structure is completely removed from the LCD panel edges, allowing pixels to be exposed and connected directly with adjacent panels. This extraction of the bezel element eliminates the discrete areas that cause image discontinuity in traditional tiled displays.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The exposed pixel regions of adjacent bezelless LCD panels are merged to form a continuous display surface. The pixels from multiple panels connect seamlessly at the edges, creating an integrated wide-screen display without visible boundaries or discrete areas.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If optical members or sub-displays are installed in connecting portions to eliminate discrete areas, then image continuity improves, but additional components and separate image processing are required

Engineering Contradiction:
Improveimage continuityVSAvoidadditional components and image processing
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Instead of adding optical members or sub-displays to the connecting portions, the invention removes the bezel structure entirely. This extraction approach achieves image continuity through direct pixel connection without requiring any additional components or complex image processing systems.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The bezelless LCD panels themselves provide the solution for image continuity through their exposed pixel edges. The panels' own pixel structures serve to create the seamless connection, eliminating the need for external optical members or separate processing systems.

Inventive Principle:
Principle #25Self-service

3Reliability

If bezelless LCD panels with exposed pixels are used, then image continuity is achieved without discrete areas, but the structure becomes more complex

Engineering Contradiction:
Improveimage continuityVSAvoidpanel structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The bezel structure is removed from the LCD panel, exposing the pixel edges. This simple extraction creates the continuous display surface needed for seamless tiling without requiring complex structural modifications to the panels themselves.

Inventive Principle:
Principle #2Taking out (Extraction)

4Ease of manufacture

If traditional LCDs with bezels are used, then manufacturing and installation follow standard procedures, but discrete areas cause installation difficulties

Engineering Contradiction:
Improvestandard manufacturing proceduresVSAvoidinstallation ease
Core Design Contradiction:

Solution Approach 1:

By removing the bezel structure, the invention simplifies the installation process. The exposed pixel edges of bezelless panels can be directly connected to form seamless displays, eliminating the complex alignment and assembly procedures required for traditional beveled panels.

Inventive Principle:
Principle #2Taking out (Extraction)
