Liquid Crystal Display Frame With Elastic Panel Fixing Members

Solution Overview

Problem

Conventional liquid crystal displays rely on expensive adhesive tape for panel fixation, which is prone to chemical instability and relative movement issues, affecting optical performance and increasing manufacturing costs.

Innovation Solution

A one-piece frame with inwardly extending supporting boards and elastic members secures the liquid crystal panel without adhesive tape, ensuring stable fixation and reduced manufacturing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If adhesive tape is used to fix the liquid crystal panel to the frame, then the panel can be secured in place, but the manufacturing cost increases and chemical stability deteriorates under high temperatures

Engineering Contradiction:

Improvefixation stabilityVSAvoidmanufacturing cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent removes the adhesive tape from the fixation system entirely. Instead of using adhesive tape to secure the liquid crystal panel, the invention uses a frame structure with pressing members that mechanically press the panel against the frame through elastic deformation, eliminating the need for adhesive materials and their associated cost and reliability issues.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the chemical bonding mechanism (adhesive tape) with a mechanical pressing system. The frame includes pressing members that elastically deform to apply continuous mechanical pressure on the liquid crystal panel, securing it through physical contact and elastic force rather than chemical adhesion.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If adhesive tape is used to fix the liquid crystal panel, then the panel can be secured, but relative movements occur between the panel and frame under thermal conditions

Engineering Contradiction:

Improvefixation stabilityVSAvoidchemical stability

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The patent removes the adhesive tape from the fixation system entirely. Instead of using adhesive tape to secure the liquid crystal panel, the invention uses a frame structure with pressing members that mechanically press the panel against the frame through elastic deformation, eliminating the need for adhesive materials and their associated cost and reliability issues.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent utilizes temperature-dependent elastic deformation of the pressing members to maintain stable fixation. As temperature changes, the elastic materials in the pressing members deform accordingly, automatically compensating for thermal expansion or contraction of the panel and frame, thereby preventing relative movement and maintaining fixation stability across different thermal conditions.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If adhesive tape is used for panel fixation, then the panel can be attached to the frame, but adhesive material contaminates the liquid crystal panel and impairs optical performance
