Display Screen Module With Protruding Driving Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display screen modules are large in size and inconvenient to maintain due to the placement of the controller on the back surface.
Innovation Solution
A display screen module design featuring a substrate with integrated first and second mounting plates, where the driving device is positioned on the first mounting plate and partially protrudes from the rear panel, allowing for a compact size and easy maintenance, with the driving device configured to supply power and signals to display assemblies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the controller is arranged on the back surface of the display screen module, then the driving device can be provided with sufficient space, but the size of the display screen module increases and maintenance becomes inconvenient
Solution Approach 1:
The patent integrates the first mounting plate and second mounting plate into a three-dimensional substrate structure, where the first mounting plate is arranged on the front surface and the second mounting plate extends from the back surface. This spatial arrangement allows the driving device to be positioned on the front surface while maintaining adequate space for controller placement, thereby reducing the overall module size while ensuring proper component layout and heat dissipation pathways.
2Ease of manufacture
If the controller is arranged on the back surface of the display screen module, then the driving device can be provided with sufficient space, but maintenance becomes inconvenient
Solution Approach 1:
The patent divides the mounting structure into two distinct mounting plates (first mounting plate on the front surface, second mounting plate on the back surface) that are integrated into a unified substrate. This segmentation allows the driving device to be accessed from the front surface for maintenance purposes, while the controller remains positioned on the back surface with adequate space, thereby improving maintenance convenience without compromising the driving device's spatial requirements.
3Volume of moving object
If the driving device is positioned on the first mounting plate protruding from the rear panel, then the size is reduced and maintenance is easier, but the thickness may be increased
Solution Approach 1:
The patent integrates the first mounting plate and second mounting plate into a nested three-dimensional substrate structure, where one mounting plate is arranged on the front surface and the other extends from the back surface. This nested arrangement allows both mounting plates to coexist within the same thickness envelope, minimizing the overall thickness increase while providing sufficient space for the driving device to protrude from the rear panel for easier maintenance access.

AI summary
Present disclosure discloses a display screen module and a display screen, which includes a front panel, a rear panel and a circuit module. The circuit module includes a driving device, a plurality of display assemblies and a substrate located between the front panel and the rear panel. The substrate includes a first mounting plate and second mounting plate which are integrated. The second mounting plate is formed by extension from one end of the first mounting plate along a horizontal direction. Each of the plurality of display assemblies includes a plurality of lamp beads provided at intervals on the substrate along an extension direction of the second mounting plate and facing the front panel. The driving device is arranged on the first mounting plate and partially protrudes from the rear panel. A size of the driving device is less than or equal to a size of the first mounting plate.
