Ultra-Thin LCD via Insert-Molded Cover Bottom and Guide Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid crystal display (LCD) devices face challenges in reducing thickness, which hinders the development of ultra-thin display devices and affects aesthetic value and space utilization.
Innovation Solution
The proposed display device integrates a liquid crystal panel, a backlight unit, a cover bottom, a rear cover, and a guide panel, where the cover bottom and guide panel are integrated using an insert injection method, allowing the cover bottom to be inserted into the guide panel, and the guide panel's outer surface is obliquely provided.

Engineering Contradiction Analysis
1Length of moving object
If the liquid crystal display includes a liquid crystal panel and a backlight unit with separate components, then the assembly is straightforward, but the thickness cannot be significantly reduced
Solution Approach 1:
The cover bottom and guide panel are merged into a single integrated component through insert injection molding. The guide panel includes an inclined part that receives and integrates with the cover bottom, eliminating the need for separate assembly steps and reducing overall thickness while maintaining structural functionality.
Solution Approach 2:
The cover bottom is nested within the guide panel structure. The inclined part of the guide panel is designed to receive and accommodate the cover bottom, creating a compact nested arrangement that reduces the vertical profile and achieves ultra-thin display device construction.
2Length of moving object
If the cover bottom and guide panel are integrated by insert injection method, then the thickness is reduced, but the manufacturing process becomes more complex
Solution Approach 1:
The cover bottom and guide panel are manufactured as a single integrated component using insert injection molding technology. This merging of components eliminates the need for separate manufacturing and assembly steps, reducing overall thickness while the integrated manufacturing process handles the complexity in a single operation.
3Length of moving object
If the guide panel surrounds all side surfaces of the cover bottom, then the structural support is maximized, but the thickness reduction is limited
Solution Approach 1:
The guide panel provides structural support selectively at critical locations rather than uniformly surrounding all surfaces. The inclined part is positioned to receive the cover bottom at the thinnest section, providing localized support where needed to maintain structural integrity while enabling thickness reduction in other areas.

AI summary
A display device and a method of assembling the display device are discussed. The display device includes a liquid crystal panel displaying an image, a backlight unit providing light to the liquid crystal panel, a cover bottom having the backlight unit mounted thereon, a rear cover accommodating the cover bottom, and a guide panel surrounding an edge of the liquid crystal panel and supporting the liquid crystal panel, wherein the cover bottom and the guide panel are integrated by an insert injection method so that an end of the cover bottom is inserted into the guide panel, and an outer surface of the guide panel is obliquely provided.
