Display Panel Positioning With Restricting and Pressing Ribs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display panels in display apparatuses are prone to damage during assembly due to improper positioning and external forces applied during the coupling of the top chassis and middle mold, leading to potential cracks that can render the panel unusable.
Innovation Solution
Incorporation of a middle mold with a restricting rib to maintain the display panel's position and a top chassis with a pressing rib that guides the panel back to its correct position, preventing movement and external forces that could cause damage, along with an indicator rib for easy assembly verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the top chassis is coupled with the middle mold during assembly, then the display apparatus is assembled, but the display panel may be damaged due to improper positioning and external forces
Solution Approach 1:
The restricting rib is pre-formed on the middle mold to establish the correct position of the display panel before the top chassis is coupled. This preliminary positioning structure ensures the panel is properly aligned and protected from damage during the assembly process, resolving the contradiction between assembly efficiency and panel integrity.
Solution Approach 2:
The pressing rib acts as an intermediary element between the top chassis and the display panel. It applies controlled pressure to guide the panel into its correct position while preventing direct contact that could cause damage, thus enabling safe assembly without compromising panel integrity.
2Adaptability or versatility
If the display panel is allowed to move during assembly, then positioning flexibility is improved, but the panel may depart from the correct position and be damaged
Solution Approach 1:
The positioning function is segmented into two distinct ribs: the restricting rib that prevents lateral movement and maintains positioning accuracy, and the pressing rib that provides vertical guidance and adaptation. This segmentation allows the system to simultaneously achieve positioning flexibility through the pressing action while maintaining accuracy through the restricting rib.
Solution Approach 2:
The pressing rib is designed to dynamically adjust its position as the top chassis is coupled with the middle mold. It moves from an initial position where it may contact the panel to a final position where it rests on the panel, providing adaptive guidance that maintains positioning accuracy throughout the assembly process.

AI summary
A display apparatus according to a concept of the disclosure includes: a display panel displaying an image in a front direction; a middle mold causing the display panel to be rested at a first position; and a chassis coupled with the middle mold in the front direction of the display panel, wherein the middle mold includes a restricting rib for restricting the display panel from departing from the first position and restricting the display panel from moving in a side direction, and the chassis includes a pressing rib being in an inclined shape and pressing the display panel toward the first position when the chassis is coupled with the middle mold in the state in which the display panel departs from the first position.
