Solution Overview
Problem
Conventional liquid crystal display (LCD) devices require numerous assembly steps and are costly due to the complex process of connecting a light-emitting diode (LED) to a printed circuit board (PCB), which complicates the assembly process.
Innovation Solution
The LCD device incorporates a light source flexible printed circuit board (FPCB) mounted with LEDs, a PCB, and a receiving container with through-holes and protrusions, allowing for direct electrical connection and secure mounting, reducing assembly steps and costs by using embossed patterns and fixing members like screws or hooks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional LED connection methods are used, then reliable electrical connections are achieved, but the number of assembly steps increases and manufacturing cost increases
Solution Approach 1:
The patent combines the LED connection structure with the receiving container by forming protrusions directly on the container that serve dual purposes: providing mechanical support for the LED and establishing electrical connections. This integration eliminates separate connection components and reduces assembly steps while maintaining reliable electrical connections.
Solution Approach 2:
The protrusions on the receiving container serve multiple functions simultaneously: they act as mechanical supports for mounting the LED, provide electrical connection paths through conductive structures, and serve as alignment features. This multi-functionality reduces the overall component count and simplifies the assembly process.
2Reliability
If conventional LED connection methods are used, then reliable electrical connections are achieved, but manufacturing cost increases
Solution Approach 1:
The patent merges the LED mounting structure with the receiving container by integrating conductive protrusions directly into the container body. This eliminates the need for separate connection components and reduces assembly steps, thereby lowering manufacturing costs while maintaining reliable electrical connections.
Solution Approach 2:
The patent changes the structural parameters of the receiving container by adding protrusions with specific geometric features that enable both mechanical support and electrical connection. This design modification allows for simpler manufacturing processes and reduced component costs while ensuring reliable electrical connections.
3Device complexity
If the LCD device structure is simplified, then assembly steps are reduced, but structural stability may be compromised
Solution Approach 1:
The patent combines the mounting and support functions into the receiving container itself through integrated protrusions. This eliminates the need for separate support structures while maintaining structural stability, as the protrusions are formed as integral parts of the container body.
Solution Approach 2:
The receiving container is designed as a composite structure combining insulating material for the container body with conductive elements for electrical connections. This composite approach maintains structural integrity and stability while enabling simplified assembly through the integrated protrusion design.

AI summary
A liquid crystal display (LCD) device includes an LCD panel displaying an image, a light source providing the LCD panel with light, a light source flexible printed circuit board (FPCB), a printed circuit board (PCB), and a receiving container. The PCB is electrically connected to the LCD panel. The PCB is in contact with two ends of the light source FPCB. The receiving container is combined with the light source FPCB and the PCB. The receiving container has a through-hole through which the light source FPCB passes. According to the present invention, the receiving container applies pressure so that both ends of the light source FPCB make contact with the PCB and the light source FPCB is electrically connected to the PCB. The light source FPCB, the receiving container, and the PCB are secured to each other. Therefore, the number of steps required to assembly the LCD device may be reduced.
