Solution Overview

Problem

Existing display apparatuses face the challenge of visually recognizable lines around transmission areas, which detract from the overall visibility and aesthetic appeal, particularly when additional functions are integrated into the display area.

Innovation Solution

The implementation of a transmission area in the display apparatus that allows lines to bypass, minimizing their visibility through strategic design and optical functional layers, such as anti-reflection and lens structures, to enhance the visual experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If various lines are arranged around the transmission area to provide additional functions, then the functionality of the display apparatus is improved, but the visibility of the lines increases and aesthetic quality deteriorates

Engineering Contradiction:
ImprovefunctionalityVSAvoidvisibility of lines
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

A light blocking layer is introduced as an intermediary element between the transmission area and the surrounding lines. This layer selectively blocks light to make the lines invisible while allowing the transmission area to maintain its light transmission properties, thus resolving the contradiction between functionality and aesthetics

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The light blocking layer is configured to match the color or optical properties of adjacent pixels, making the lines blending with the display area. This color matching approach allows the lines to become visually imperceptible while maintaining the functional integrity of the display

Inventive Principle:
Principle #32Color changes

2Adaptability or versatility

If the transmission area is expanded to add various functions, then the versatility of the display apparatus is improved, but the area available for displaying images may be reduced

Engineering Contradiction:
ImproveversatilityVSAvoiddisplay area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The light blocking layer is applied locally only around the transmission area where lines are present, rather than across the entire display. This localized approach allows the transmission area to be expanded for additional functions while minimizing the impact on the overall display area and maintaining image quality in the display region

Inventive Principle:
Principle #3Local quality
