Solution Overview

Problem

Current display devices with full-screen designs face challenges in improving display quality due to occupied areas by functional components like optical assemblies, which hinder seamless image display and reduce pixel density.

Innovation Solution

A display device with a flexible screen and movement assembly that slides relative to the display window, allowing the light-transmitting area to be outside the display window in full-screen mode, thereby improving display quality by maintaining high pixel density and reducing manufacturing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If functional components like optical assemblies are integrated into the display screen, then device functionality is enhanced, but display quality deteriorates due to occupied areas and reduced pixel density

Engineering Contradiction:

Improvedevice functionalityVSAvoiddisplay quality

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The patent extracts the light-transmitting area from the display window area, allowing the optical assembly to be positioned outside the display region. This separation enables the display screen to maintain full pixel density across the entire display window while still accommodating the optical assembly for functions like facial recognition or ambient light sensing.

Inventive Principle:

Principle #2Taking out (Extraction)

2Area of stationary object

If a full-screen design is implemented, then display area is maximized, but display quality deteriorates due to occupied areas by functional components

Engineering Contradiction:

Improvedisplay areaVSAvoiddisplay quality

Core Design Contradiction:

Area of stationary objectVSManufacturing precision

Solution Approach 1:

The patent resolves the spatial conflict by transitioning from a two-dimensional planar arrangement to a three-dimensional configuration. The light-transmitting area is positioned in a different spatial zone (outside the display window), allowing both the full display area and functional components to coexist without compromising display quality or maximizing screen real estate.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If the light-transmitting area is positioned within the display window, then optical function is enabled, but display quality deteriorates due to reduced pixel density in occupied areas

Engineering Contradiction:

Improveoptical functionVSAvoidpixel density

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

Inventive Principle:

Principle #2Taking out (Extraction)
