Display Module Visible Region Extension Member Border Width

Solution Overview

Problem

Current display modules with black baffle frames to define display regions result in increased borders and decreased screen-to-body ratios, compromising the aesthetic appeal and functionality of mobile devices.

Innovation Solution

Incorporating a visible region extension member, such as a triangular or rectangular prism or illuminant, between the cover and black baffle frame to create a seamless integration of display and bright regions, reducing perceived borders and enhancing the screen-to-body ratio.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a black baffle frame is used to define the display region, then the display region is clearly defined, but the border width increases and the screen-to-body ratio decreases

Engineering Contradiction:

Improvedisplay region definitionVSAvoidborder width

Core Design Contradiction:

Manufacturing precisionVSLength of stationary object

Solution Approach 1:

The patent extracts the light-blocking function from the traditional black baffle frame structure. By using a separate light-blocking layer applied directly to the display panel, the need for a protruding physical frame is eliminated, thereby reducing border width while maintaining display region definition.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the display panel and the light-blocking function into a single integrated structure. The light-blocking layer is directly formed on the display panel surface, combining the functions of display and border definition in one component, thus eliminating the need for additional frame structures.

Inventive Principle:

Principle #5Merging (Combining)

2Manufacturing precision

If a black baffle frame is used to define the display region, then the display region is clearly defined, but the visible region area decreases

Engineering Contradiction:

Improvedisplay region definitionVSAvoidvisible region area

Core Design Contradiction:

Manufacturing precisionVSArea of stationary object

Solution Approach 1:

The patent extracts the light-blocking function from the traditional black baffle frame structure. By using a separate light-blocking layer applied directly to the display panel, the need for a protruding physical frame is eliminated, thereby reducing border width while maintaining display region definition.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent transitions from a three-dimensional protruding frame structure to a two-dimensional planar light-blocking layer. This dimensional change allows the border definition to be achieved within the plane of the display panel without adding vertical depth, thus maximizing the visible region area.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Device complexity

If the cover side portion is disposed directly on the black baffle frame, then the structure is simple, but the border appears wide and the screen integration is poor

Engineering Contradiction:

Improvestructural simplicityVSAvoidscreen integration

Core Design Contradiction:

Device complexityVSShape

Solution Approach 1:

The patent merges the display panel and the light-blocking function into a single integrated structure. The light-blocking layer is directly formed on the display panel surface, combining the functions of display and border definition in one component, thus eliminating the need for additional frame structures.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a light-blocking layer as an intermediary between the display panel and the cover. This intermediate layer provides a smooth transition surface that improves optical integration and reduces the visual perception of borders, while the cover can still be simply disposed over the entire assembly.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The disclosure is related to a display module comprising a display panel and a cover. The display panel includes a black baffle frame defining a display region on the display panel. The cover is disposed on the display panel, and a side portion of the cover is on the black baffle frame. The display module further includes a visible region extension member disposed between the side portion of the cover and the black baffle frame. The disclosure further discloses a display device having the display module. In the disclosure, a bright region is formed on the black baffle frame at the periphery of the display region, and the bright region and the display region connect with each other as a whole to form an integrated screen such that viewers visually feel that the border of the display device is narrowed and the visible region of the screen is extended.
