Upright Case Member for Direct LCD Panel Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
LCD devices face limitations in reducing thickness due to the presence of a guide panel between the backlight unit and the liquid crystal panel, which restricts aesthetic appearance and thickness reduction.
Innovation Solution
The implementation of an upright-type case member that supports the liquid crystal display panel directly on the backlight unit, eliminating the need for a separate guide panel by bending the case member to protrude and stabilize the panel, thereby allowing direct attachment and reducing overall thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a guide panel is disposed between the backlight unit and the liquid crystal panel to enable stable positioning, then the positioning stability is improved, but the overall thickness of the LCD device increases
Solution Approach 1:
The patent combines the guide panel's positioning function with the case member structure. The case member includes a guiding portion that directly guides the liquid crystal panel onto the backlight unit, merging the support and positioning functions into a single integrated component, thereby eliminating the need for a separate guide panel and reducing device thickness
Solution Approach 2:
The case member is designed to perform multiple functions: it provides structural support, positioning guidance, and panel stabilization all through one component. The guiding portion of the case member simultaneously serves as both a structural element and a positioning mechanism, achieving multi-functionality that reduces the number of separate components needed
2Strength
If a guide panel is used to support the liquid crystal panel, then the structural support is improved, but the device complexity increases due to additional components
Solution Approach 1:
The patent merges the guide panel's structural support function into the case member itself. The case member's guiding portion provides the necessary structural support and positioning guidance, eliminating the need for a separate guide panel component and thereby reducing device complexity
Solution Approach 2:
The patent extracts the positioning and support function from the separate guide panel component and integrates it into the case member structure. This extraction of the essential function from its original separate component allows for simplification of the overall device architecture

AI summary
Disclosed is an LCD device. The LCD device includes an upright-type case member including a supporting surface, a backlight unit attached on the supporting surface, and a liquid crystal display panel directly attached on the backlight unit. The upright-type case member is bent from one edge of the supporting surface and protrudes to a front surface of the liquid crystal display panel. Since the liquid crystal display panel is directly attached on the backlight unit, a separate element for enabling the liquid crystal display panel to be stably disposed on the backlight unit is not needed, and thus, a thickness of the LCD device does not increase.
