Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The stacking of multiple PCB boards with varying heights and dimensions in liquid crystal panel assemblies often results in damage to the Chip on Film (COF) due to bending or warpage, affecting the quality of the panels.
Innovation Solution
A liquid crystal panel assembly is designed with a flexible wiring board and circuit board connection system, where the wiring board is fixedly connected to the liquid crystal panel and the circuit board through adhesive, and the circuit board is connected to the wiring board using plug and socket elements, preventing damage from component height and dimension variations.

Engineering Contradiction Analysis
1Productivity
If multiple PCB boards are stacked together in the support tray, then the support tray can accommodate multiple liquid crystal panels economically, but the COFs are damaged due to bending or warpage caused by varying heights and dimensions of electronic components
Solution Approach 1:
The support tray is divided into multiple independent compartments, each designed to hold a single PCB board vertically. This segmentation prevents the boards from contacting each other and eliminates the warpage problem caused by stacking, while still allowing multiple panels to be accommodated in the same tray through increased organizational structure.
Solution Approach 2:
Instead of stacking PCB boards horizontally in layers (2D stacking), the invention transitions to vertical stacking where each PCB board stands upright in its own compartment. This dimensional change eliminates contact between boards and prevents COF damage while maintaining high stacking capacity.
2Productivity
If PCB boards with varying component heights are stacked, then multiple panels can be placed in the support tray, but the wiring boards experience bending and warpage affecting connection integrity
Solution Approach 1:
The support tray is segmented into individual compartments that isolate each PCB board. This prevents the transmission of mechanical stress and deformation between adjacent boards, ensuring that connection integrity is maintained even when boards have different component heights and dimensions.
Solution Approach 2:
The support tray compartments act as intermediary structures that physically separate PCB boards. These compartments provide a stable supporting environment for each board independently, preventing direct contact and the resulting warpage that would compromise connection precision.

AI summary
The liquid crystal panel packaging assembly contains a liquid crystal panel assembly and a support tray. The liquid crystal panel assembly contains a liquid crystal panel, a wiring board, and a circuit board. The wiring board has a first end electrically connected to the liquid crystal panel and a second end configured with a first connection element. The circuit board has a second connection element for connection with the first connection element so that the circuit board is electrically connected to the wiring board. The support tray contains a first indentation for receiving the liquid crystal panel, a second indentation for receiving the wiring board, and at least a socket. The second indentation is at a side and is connected to the first indentation. The socket is located at a lateral side of the second indentation, and the circuit board is plugged into the socket.
