Backlight Frame Assembly for Tiled Display Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is difficult to assemble the display panel and the backlight module in tiled display devices.
Innovation Solution
A display device is provided with a backlight module that includes a frame with a first supporting surface attached to the display panel and a second supporting surface engaged with a light guiding structure, facilitating the assembly of the display panel and the backlight module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional assembly method is used to assemble the display panel and backlight module, then the assembly process is simple, but the assembly difficulty is high and structural integrity is poor
Solution Approach 1:
A frame is introduced as an intermediary component between the display panel and backlight module. The frame includes a first supporting surface that attaches to the display panel and a second supporting surface that engages with the light guiding structure, serving as a mediator to connect these two components and facilitate assembly.
Solution Approach 2:
The frame is divided into multiple functional surfaces: a first supporting surface for attaching to the display panel, a second supporting surface for engaging the light guiding structure, and connecting portions that link these surfaces together. This segmentation allows each surface to perform its specific function independently while maintaining overall structural integrity.
2Device complexity
If the frame structure is simplified, then the device complexity is reduced, but the structural integrity and assembly stability deteriorate
Solution Approach 1:
The frame extends in multiple dimensions with connecting portions that link the first and second supporting surfaces. These connecting portions include first connecting portions attached to the display panel and second connecting portions engaged with the light guiding structure, creating a three-dimensional stable structure that prevents deformation.
Solution Approach 2:
The frame is constructed as a composite structure combining rigid connecting portions with supporting surfaces that have specific attachment characteristics. The first supporting surface has a first attachment characteristic for bonding to the display panel, while the second supporting surface has a second attachment characteristic for engaging the light guiding structure, creating a multi-functional composite component.
