Rigid Light Guide Plate Frame for Thin Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in achieving a lower profile and narrower frame border due to the presence of multiple casing members, which hinders designability and increases component count and weight.
Innovation Solution
A display device design that incorporates a light guide plate with rigidity, where the edge surface is attached to a frame, allowing for the elimination of unnecessary chassis members such as the middle chassis, back chassis, and rear cover, and uses a sealing member and bonding film to secure the display panel, reducing the number of components and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If multiple casing members are used to accommodate the display panel, then the structural stability is improved, but the device thickness and weight increase
Solution Approach 1:
The patent merges multiple casing members (front chassis, middle chassis, back chassis) into a single integrated frame structure. This frame directly supports the display panel and light guide plate, eliminating the need for separate middle and back chassis while maintaining structural stability. The bonding film and sealing member further integrate components, reducing overall device thickness.
Solution Approach 2:
The frame structure serves multiple functions simultaneously: it acts as the primary casing, provides structural support, holds the display panel, and accommodates the light guide plate. This multi-functional design replaces what would traditionally require separate dedicated components for each function, thereby reducing device thickness.
2Stability of the object's composition
If multiple casing members are used to accommodate the display panel, then the structural stability is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple discrete casing members into a single integrated frame structure. Instead of having separate front chassis, middle chassis, and back chassis, the design uses one frame that performs all structural functions, directly reducing component count and device complexity while maintaining stability.
Solution Approach 2:
The frame is designed as a universal component that simultaneously provides structural support, houses the display panel, and accommodates optical components. This multi-functionality eliminates the need for multiple specialized components, simplifying the overall device architecture.
3Stability of the object's composition
If multiple casing members are used to accommodate the display panel, then the structural stability is improved, but the device weight increases
Solution Approach 1:
The patent merges multiple heavy casing members into a single frame structure, reducing the total amount of material required. By eliminating redundant middle and back chassis, the overall device weight is reduced while the frame maintains necessary structural stability through optimized design.
4Length of moving object
If the frame structure is simplified to reduce component count, then the device thickness is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The patent introduces a bonding film as an intermediary component between the frame and the display panel/light guide plate. This bonding film facilitates precise alignment and secure attachment, compensating for the simplified frame structure and ensuring high assembly precision without requiring complex machining or fitting procedures.
Solution Approach 2:
The sealing member acts as an intermediary element that ensures precise positioning and sealing between components. It facilitates accurate assembly while maintaining the simplified frame structure, thereby achieving thin device profile without compromising manufacturing precision.
