Solution Overview

Problem

The challenge is to achieve a full-screen display on mobile devices without damaging the screen integrity and introducing new mechanical structures, as traditional methods either compromise the screen integrity or have limitations such as slow camera pop-up speed and high failure rates due to mechanical complexities.

Innovation Solution

A display panel design featuring a main display region and a function additional region, where the function additional region is surrounded by the main display region and uses independently controlled light source blocks for illumination, allowing the function additional region to switch between transparent and display states, enabling full-screen functionality without mechanical structures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the front panel is cut out to allow light transmission for electronic components, then the electronic components can operate normally, but the screen integrity is destroyed and full-screen display cannot be achieved

Engineering Contradiction:

Improveelectronic component operationVSAvoidscreen integrity

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The display screen is segmented into a main display region and a function additional region (transparent region). The transparent region is further divided into multiple sub-regions that can be independently controlled. This segmentation allows the screen to maintain overall integrity while creating dedicated areas for electronic component light transmission.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The transparent display region uses dynamically controllable light sources (LEDs or OLEDs) that can be turned on or off based on operational needs. When electronic components need to function, the corresponding transparent region illuminates to allow light transmission; when not needed, the light sources are turned off to maintain full-screen display capability.

Inventive Principle:

Principle #15Dynamics

2Stability of the object's composition

If mechanical structures are introduced to enable camera pop-up or sliding functions, then full-screen display can be achieved, but the pop-up speed becomes slow and the failure rate increases

Engineering Contradiction:

Improvefull-screen displayVSAvoidmechanical structure reliability

Core Design Contradiction:

Stability of the object's compositionVSReliability

Solution Approach 1:

The patent replaces mechanical pop-up or sliding structures with an optical control system. Instead of physically moving camera modules using motors and mechanical linkages, the invention uses controllable transparent display regions with light sources that can be activated or deactivated electronically. This substitution eliminates mechanical failure points while maintaining full-screen display capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If mechanical structures are used for camera pop-up functions, then the camera can be hidden when not in use, but the assembly process creates gaps that are susceptible to powder and dust intrusion

Engineering Contradiction:

Improvecamera hiding functionVSAvoiddust and powder intrusion

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The invention replaces mechanical opening/closing mechanisms with an optical control system. The transparent display region can be electronically activated or deactivated without any physical movement, eliminating gaps that would allow dust and powder to enter the device interior.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Reliability

If the screen is cut out for electronic components, then light transmission is enabled, but the area of the display screen is reduced

Engineering Contradiction:

Improveelectronic component operationVSAvoiddisplay screen area

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The transparent display region serves multiple functions: it allows light transmission when electronic components are active, and it can function as a display area when illuminated. This multi-functionality ensures that the full screen area is utilized for display purposes while still enabling electronic component operation when needed.

Inventive Principle:

Principle #6Universality (Multi-functionality)
