Rubber Frame with Metal Projections for Antistatic Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Liquid crystal display devices have weak antistatic ability due to their narrow bezel design, which allows static charges to easily enter and potentially damage the internal leads, and they also suffer from poor impact resistance due to the omission of a metal backboard.
Innovation Solution
A rubber frame component with pointy projections made of conductive materials, such as metal, is used to attract and dissipate static charges around the display panel, and a reinforcing part is integrated to enhance impact resistance by supporting the display panel and buffering against collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a narrow bezel design is used to expand viewing area, then the area of the display device is improved, but the antistatic ability deteriorates because static charges can easily enter and damage internal leads
Solution Approach 1:
The patent applies preliminary action by positioning pointy projections made of conductive material on the rubber frame before static charges can reach the internal leads. These projections create a preliminary discharge path that intercepts static charges in advance, preventing them from causing damage to the display panel's internal leads while maintaining the narrow bezel design.
2Weight of moving object
If a metal backboard is omitted to achieve thin profile, then the weight and thickness are reduced, but the impact resistance deteriorates
Solution Approach 1:
The patent applies composite materials by integrating a reinforcing part made of rigid material into the rubber frame component. This creates a composite structure that combines the flexibility and antistatic properties of rubber with the strength and impact resistance of rigid materials, eliminating the need for a separate metal backboard while maintaining both weight reduction and impact protection.
3Strength
If a reinforcing part is added to improve impact resistance, then the strength is improved, but the device complexity increases
Solution Approach 1:
The patent applies merging by integrating the reinforcing part directly into the rubber frame component as a unified structure. The rigid reinforcing part is embedded within or attached to the rubber frame, combining multiple functions (frame support, reinforcement, and antistatic protection) into a single integrated component, thereby improving impact resistance without significantly increasing device complexity.
