Display Apparatus Removable PC Board Assembly Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection structure of personal computer (PC) board assemblies in display apparatuses, such as PDP TVs, makes it difficult to replace components efficiently, as they are mounted at the rear and interfere with the display unit's operation, leading to service inefficiencies.
Innovation Solution
A display apparatus design featuring a supporting frame with a guide member and a slidably removable motherboard assembly that does not directly influence the display unit's operation, allowing for easy replacement and maintenance while maintaining the display's functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the PC board assembly is mounted at the rear side of the display apparatus, then the display apparatus can achieve a thin and large display panel, but the board assembly causes difficulty in replacement when disordered
Solution Approach 1:
The PC board assembly is segmented from the main display structure by using a separate supporting frame that can be independently removed. This allows the board assembly to be replaced without affecting the display panel itself, resolving the contradiction between achieving thin display panel volume and maintaining ease of repair.
Solution Approach 2:
The PC board assembly is extracted from the integrated display structure and mounted on a separate supporting frame. This extraction enables independent removal and replacement of the board assembly from the rear side, maintaining thin display panel thickness while significantly improving serviceability.
2Area of stationary object
If the PC board assembly is mounted at the rear side of the display apparatus, then spatial efficiency is improved for wall-hanging installation, but service efficiency is deteriorated
Solution Approach 1:
The supporting frame with PC board assembly is segmented as a separate serviceable unit from the display panel. This segmentation allows maintenance personnel to access and replace the board assembly from the rear side without removing the display from the wall, thus maintaining wall space utilization while improving service efficiency.
Solution Approach 2:
The PC board assembly is extracted into a separately accessible component mounted on the supporting frame. This extraction enables quick removal and replacement of the board assembly from the rear side, maintaining the compact wall-hanging configuration while significantly improving service productivity.

AI summary
A display apparatus improved in the structure to connect a board assembly having a personal computer (PC) function. The display apparatus includes a display module embodying an image, a supporting frame disposed at a rear part of the display module, a plurality of driving circuit boards mounted to the supporting frame to drive the display module, a guide member disposed at one side of the plurality of driving circuit boards, a board assembly removably connected to the guide member but not electrically connected with the driving circuit boards, and a rear cover covering the display module and the supporting frame while providing a space for the board assembly to be connected to the guide member with one side exposed.
