Solution Overview

Problem

Current splice display screens suffer from wide splicing seams due to the need to accommodate circuit boards and wires, which affects the display effect and is exacerbated by the visibility of internal structures through transparent displays.

Innovation Solution

A unit display screen design featuring a frame with a first part and a second part that projects outward to house the circuit board and wire, with the second frame being shorter and narrower to minimize seam width, allowing for efficient splicing and shielding of components without increasing the seam width.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the frame width is increased to accommodate the circuit board and wire for shielding purposes, then the circuit board and wire can be properly shielded, but the splicing seam width becomes remarkably wider and more difficult to remove

Engineering Contradiction:
Improveshielding effectVSAvoidsplicing seam width
Core Design Contradiction:
Object-affected harmful factorsVSLength of stationary object

Solution Approach 1:

The patent applies dimensionality change by extending the frame in the depth direction (perpendicular to the display panel) to create a chamber that houses the circuit board and wire. This allows the frame to provide shielding functionality without increasing its width in the plane direction, thereby resolving the contradiction between shielding effectiveness and splicing seam width.

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

2Object-affected harmful factors

If the frame width is increased to accommodate shielding components, then the circuit board and wire can be shielded, but the black splicing seam between adjacent unit display screens becomes wider and more difficult to be removed

Engineering Contradiction:
Improvevisibility of internal structuresVSAvoidsplicing seam width
Core Design Contradiction:
Object-affected harmful factorsVSLength of stationary object

Solution Approach 1:

The frame is extended in the depth direction to form a chamber that contains the circuit board and wire. This dimensional extension provides shielding against visible internal structures through transparent displays without increasing the frame's width, thus preventing wider splicing seams.

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

3Ease of manufacture

If the frame width is increased to accommodate the circuit board and wire, then proper accommodation and shielding are achieved, but the display effect is affected due to wider splicing seams

Engineering Contradiction:
Improveaccommodation of componentsVSAvoiddisplay effect
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The frame structure is extended in the depth direction to create a chamber for accommodating components, rather than increasing the frame width. This allows proper component accommodation while maintaining narrow splicing seams and preserving display effect.

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

4Object-affected harmful factors

If the frame width is increased to accommodate shielding components, then the circuit board and wire can be shielded, but the splicing seam becomes more difficult to be removed

Engineering Contradiction:
Improveshielding capabilityVSAvoidsplicing seam removal difficulty
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The frame is extended in the depth direction to form a chamber that houses shielding components. This dimensional approach provides shielding capability without increasing frame width, thereby keeping splicing seams narrow and easier to remove.

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

AI summary

A unit display screen, a splice display screen and a display device are provided. The unit display screen comprises a display panel and a frame surrounding the display panel, wherein the frame comprises a first frame which includes a first part (21 a) and a second part (21b) sequentially in a direction away from the display panel, the second part (21b) protruding towards an outer side of the display panel with respect to the first part (21a) and having a chamber for accommodating a circuit board (41) and a wire (51). The unit display screen can solve the problem of widening the splicing seam in prior art caused by shielding the circuit board and the wire.
