Solution Overview

Problem

Conventional information handling systems face thermal dissipation challenges, particularly when transitioning between operating modes, which can lead to increased temperatures and potential damage such as delamination of the display due to rapid brightness changes.

Innovation Solution

A method involving an absorption layer composed of acrylic polymer and granulated graphene or silver, coupled with a reflective layer, manages thermal dissipation by absorbing visible light and heat leakage, transferring heat away from the display, and modifying transition periods to prevent temperature-induced damage, using a thermal controller to adjust operating modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the light source emits visible light with increased brightness in enhanced mode, then the display performance is improved, but the temperature within the display increases causing delamination

Engineering Contradiction:

ImprovebrightnessVSAvoidtemperature

Core Design Contradiction:

Illumination intensityVSTemperature

Solution Approach 1:

The patent extracts and separates the light leakage and heat generation issues by introducing an absorption layer that specifically targets and absorbs the leaked visible light and associated heat, preventing these harmful elements from causing delamination while allowing the enhanced brightness mode to operate

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The absorption layer converts the harmful light leakage and heat that would cause delamination into a beneficial thermal management solution by absorbing the excess heat and transferring it to the display cover, where it can be dissipated safely, thus protecting the display during high-brightness operation

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

2Speed

If the operating mode changes rapidly from normal mode to enhanced mode, then the response speed is improved, but the thermal shock causes delamination of the display

Engineering Contradiction:

Improveresponse speedVSAvoiddisplay integrity

Core Design Contradiction:

SpeedVSReliability

Solution Approach 1:

The absorption layer is pre-installed and positioned between the light source and display cover, ready to immediately absorb excess heat and light leakage when the enhanced mode is activated, preventing thermal shock before it can cause delamination

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The absorption layer acts as an intermediary component that mediates between the light source generating heat and the display cover, absorbing and transferring heat gradually to prevent direct thermal shock to the display structure during rapid mode transitions

Inventive Principle:

Principle #24Intermediary (Mediator)

3Temperature

If an absorption layer is added to manage thermal dissipation, then the thermal management is improved, but the device complexity increases

Engineering Contradiction:

Improvethermal dissipationVSAvoiddisplay structure

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

The absorption layer serves multiple functions simultaneously: it absorbs light leakage to improve display quality, absorbs excess heat for thermal management, and transfers heat to the display cover for dissipation, thereby addressing multiple problems with a single component

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The absorption layer is constructed from composite materials that combine light-absorbing properties with thermal conduction capabilities, enabling it to perform both optical and thermal management functions within a single integrated layer

Inventive Principle:

Principle #40Composite materials
