Liquid Crystal Display Bezel Reduction via Guide Panel Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid crystal displays face limitations in reducing bezel size due to the volume of the guide panel, which supports the backlight and liquid crystal panel, making it difficult to achieve a slim and visually larger screen design.
Innovation Solution
A liquid crystal display design where the backlight is disposed within a support frame without additional modulation, featuring a partitioned storage space for the backlight unit and a gap between the liquid crystal display panel and the backlight unit, allowing for a slim and bezel-reduced structure by eliminating the need for a bulky guide panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a guide panel is used to support the backlight unit and liquid crystal display panel, then structural stability is improved, but bezel size increases and device thickness increases
Solution Approach 1:
The invention extracts and eliminates the guide panel from the display structure. By directly mounting the backlight unit to the lower casing and the liquid crystal display panel to the cover glass, the intermediate guide panel is removed, thereby reducing bezel size while maintaining structural stability through direct mounting arrangements.
Solution Approach 2:
The invention merges the support functions previously performed by the guide panel into the lower casing and cover glass structures. The lower casing directly supports the backlight unit, and the cover glass directly supports the liquid crystal display panel, eliminating the need for a separate guide panel and reducing overall device thickness.
2Stability of the object's composition
If a guide panel is used to support the backlight unit and liquid crystal display panel, then structural stability is improved, but device thickness increases
Solution Approach 1:
The guide panel is extracted and removed from the display assembly. By eliminating this intermediate component, the overall device thickness is reduced while structural stability is maintained through direct mounting of components to the casing and cover glass.
Solution Approach 2:
The support functions of the guide panel are merged into the lower casing and cover glass. This integration eliminates the need for additional thickness to accommodate a separate guide panel structure while maintaining adequate structural support.
3Ease of manufacture
If an intermediate LCM product is used in manufacturing, then manufacturing process is simplified, but device volume increases and bezel reduction is limited
Solution Approach 1:
The display device is segmented into independent mounting structures: the backlight unit is separately mounted to the lower casing, and the liquid crystal display panel is separately mounted to the cover glass. This segmentation eliminates the need for the intermediate LCM product, reducing device volume while maintaining manufacturing feasibility through modular assembly.

AI summary
A liquid crystal display includes a support frame having a partitioned storage space; a backlight unit disposed in the storage space; a liquid crystal display panel disposed over the backlight unit and spaced apart from the backlight unit by a gap; and a cover window combined with the support frame such that the liquid crystal display panel is attached to the cover window.
