Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels, such as organic light emitting display panels, face heat management issues due to heat generated by the driver and display components, which can lead to malfunction if not effectively dissipated.
Innovation Solution
A window member with a base substrate having a display area and a non-display area, featuring a color pattern and a heat-discharge member, typically made of carbon, graphene, or graphite materials, that absorbs and discharges heat to the outside, with protective layers to prevent deformation and enhance light transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a conventional window member structure is used, then the display panel can be assembled, but heat generated by the driver and display components accumulates causing malfunction
Solution Approach 1:
The patent applies the 'Blessing in disguise' principle by converting the harmful heat generated by the driver and display components into a beneficial effect through the heat-discharge member. The heat-discharge member, made of carbon material with high thermal conductivity, absorbs the harmful heat and dissipates it to the surroundings, transforming the thermal hazard into an effective heat management solution that prevents display panel malfunction.
Solution Approach 2:
The patent applies the 'Parameter changes' principle by changing the thermal conductivity parameter of the window member structure. The heat-discharge member is specifically designed with high thermal conductivity (through carbon material selection) to enhance heat dissipation capability, fundamentally altering the thermal management parameters of the overall display apparatus compared to conventional window members.
2Temperature
If a heat-discharge member with high thermal conductivity is added, then heat dissipation is improved, but the device structure becomes more complex
Solution Approach 1:
The patent applies the 'Merging' principle by integrating the heat-discharge member with the existing window member structure. Rather than creating a completely separate heat management system, the carbon material layer is combined with the window member (which may be a touch panel or protective glass), merging the structural and thermal management functions into a unified component that reduces overall device complexity.
Solution Approach 2:
The patent applies the 'Universality' principle by designing the window member to serve multiple functions: it maintains its original structural and protective roles while simultaneously incorporating heat dissipation functionality through the carbon material layer. This multi-functional design eliminates the need for separate dedicated heat management components, thereby reducing device complexity.
3Temperature
If carbon material is used for heat discharge, then thermal conductivity is improved, but the color pattern visibility may be affected
Solution Approach 1:
The patent applies the 'Local quality' principle by strategically positioning the heat-discharge member (carbon material layer) in specific regions where heat generation occurs, such as near the driver and display components. The color pattern areas maintain their original optical properties for visibility, while the heat-discharge regions are optimized for thermal conductivity, creating localized functional zones that satisfy both requirements simultaneously.

AI summary
A window member includes a base substrate that includes a display area transmitting a light and a non-display area disposed adjacent to the display area, a color pattern disposed on a surface of the base substrate in the non-display area, and a heat-discharge member that covers the color pattern and absorbs a heat to discharge the heat to an outside.
