Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat dissipating devices are installed on the backside of display panels, then heat dissipation efficiency is improved, but the display panel may sustain excessive forces or pressure causing abnormal image display or damage
Solution Approach 1:
The heat dissipating device is divided into multiple independent heat dissipating blocks that are distributed across the backside of the display panel. Each block independently dissipates heat from specific heat-generating components, reducing concentrated pressure on any single area of the panel while maintaining effective heat dissipation across the entire panel surface.
2Temperature
If large amounts of fans or related devices are used for heat dissipation, then heat dissipation requirements are satisfied, but excessive noise is generated
Solution Approach 1:
The patent replaces the mechanical fan-based forced convection system with a passive heat dissipation system utilizing heat conduction blocks and natural convection. Heat is conducted from the display panel through thermally conductive blocks to heat dissipation structures that rely on natural air convection and radiation, eliminating the need for noisy mechanical fans while still meeting heat dissipation requirements.
3Temperature
If the backside of the display panel is used for heat dissipation, then heat can be conducted away from the panel, but the panel may be damaged by excessive pressure
Solution Approach 1:
Heat dissipating blocks are strategically positioned only in areas where heat is generated by components such as backlight units and circuit boards, rather than covering the entire backside of the display panel. This localized approach ensures effective heat removal from critical areas while leaving sufficient space and structural integrity for the display panel itself.
