Externally Connectable Thin Display Architecture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional thin displays, such as LCDs, are limited in thickness due to integrated display electronics and heavy EMI shielding, which restricts their slimness and increases weight, making them less aesthetically pleasing and costly to ship.
Innovation Solution
The display architecture separates the power supply module from the display chassis, allowing for a thinner design by positioning it externally and using a hinge or other moveable couplings, eliminating the need for a heavy metal frame and reducing EMI shielding, while maintaining compatibility with high-definition content and bi-directional communication standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If display electronics and power supply module are integrated inside the display chassis, then the display can be self-contained and structurally rigid, but the display thickness increases and weight increases
Solution Approach 1:
The display system is divided into two separate modules: a thin display module containing only the display panel, and an external power supply module containing all electronics. This segmentation allows the display module to be extremely thin while the electronics are housed externally, resolving the contradiction between thinness and functional completeness.
Solution Approach 2:
The power supply module and display electronics are extracted from the display chassis and positioned externally. This extraction removes the bulky electronic components and heavy EMI shielding from the display module, enabling it to be much thinner and lighter while maintaining all necessary functions through wireless or cable connections.
2Object-affected harmful factors
If heavy metallic EMI shielding is used to protect against electromagnetic interference, then EMI protection is improved, but the display weight increases and thickness increases
Solution Approach 1:
The heavy metallic EMI shielding is extracted from the display module and relocated to the external power supply module. Since the power supply module contains the electronic components that generate EMI, positioning the shielding there provides effective protection while keeping the display module thin and light.
3Strength
If a heavy metal frame is used to provide structural rigidity, then structural strength is improved, but the display weight increases and thickness increases
Solution Approach 1:
The heavy metal frame is extracted from the display module and relocated to the external power supply module, where it provides structural support for the electronics. This allows the display module to use a much lighter frame structure, significantly reducing weight and thickness.
4Area of stationary object
If display electronics are integrated inside the display chassis, then the display is self-contained, but the display takes up more desk space
Solution Approach 1:
The display system is segmented into a compact display module and a separate power supply module. The display module can be positioned on the desk taking up minimal space, while the power supply module can be placed elsewhere, effectively reducing the desk space requirement while maintaining system functionality through the separation of functions.

AI summary
A display system includes a display chassis defining a display chassis housing. A display panel is located in the display chassis housing. A power supply module chassis defines a power supply module housing and is coupled to the display chassis outside of the display chassis housing. A power supply module is located in the power supply module housing and coupled to the display panel. Such display system architecture allows the display chassis to be much thinner than conventional externally connectable display chassis.
