LCD Wire Holder Groove Design for Light Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LCD devices, especially the edge type, the wire connecting the lamp to the inverter can cause short circuits and interference with optical sheets due to motion, leading to uneven luminance and light leakage.
Innovation Solution
A wire holder with a groove and protrusion design is integrated into the bottom cover, allowing the wire to be securely collected and limiting its motion, preventing contact with optical sheets and reducing light leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wire is allowed to move freely for easy installation, then ease of operation is improved, but reliability deteriorates due to short circuits and interference with optical sheets
Solution Approach 1:
The wire management system is divided into separate functional segments: the groove structure provides routing guidance while the protrusion structure provides securing function. This segmentation allows the wire to be easily routed during installation while being reliably secured in position during operation, resolving the contradiction between ease of installation and connection stability.
Solution Approach 2:
The groove and protrusion structures act as intermediary elements between the wire and the housing. These intermediaries guide and secure the wire without requiring direct complex fastening mechanisms, enabling easy installation while maintaining reliable wire positioning and preventing contact with optical sheets.
2Ease of manufacture
If the wire holder structure is simplified for ease of manufacture, then ease of manufacture is improved, but device complexity increases due to inadequate wire management
Solution Approach 1:
The wire holder functionality is merged with existing housing structures through the groove and protrusion features. Instead of adding a separate complex wire management device, the housing itself is modified with simple groove and protrusion structures that provide complete wire management functionality, easing manufacture while reducing overall device complexity.
Solution Approach 2:
The groove and protrusion structures serve multiple functions simultaneously: they guide wire routing, secure wire position, prevent wire movement, and isolate the wire from optical sheets. This multi-functionality eliminates the need for separate wire management components, simplifying both manufacture and device structure.

AI summary
An LCD device having a wire holder are disclosed, in which a wire from a lamp is efficiently fixed to an inverter through a lead-out space formed at the edge of one side of a bottom cover. The LCD device has a bottom cover with bottom and lateral sides extending from the bottom, provided with a groove formed by partially cutting the bottom and the lateral sides at the edge, a light guide plate in the bottom cover, a lamp between one side of the light guide plate and one side of the bottom cover, a wire connected to both ends of the lamp and extending along the side of the bottom cover to the groove, a wire holder to which the wire is inserted to collect the wire in the groove, limiting motion of the wire, and an LCD panel arranged on the light guide plate.
