Narrow Bezel LCD Cover Bottom Supporting Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in liquid crystal displays is to minimize the bezel area, which limits the effective display size due to the structural constraints of the guide panel supporting the liquid crystal display panel and the backlight unit, making it difficult to reduce the bezel area effectively.
Innovation Solution
The implementation of a liquid crystal display design that includes a cover bottom with side walls and a supporting member that surrounds the external surface of the cover bottom, extending from the upper part of the light guide plate to the inside of the cover bottom, supports the liquid crystal display panel, thereby reducing the bezel area occupied by the guide panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a guide panel is used to support the liquid crystal display panel and maintain distance between optical sheets, then structural stability is improved, but the bezel area increases
Solution Approach 1:
The invention extracts the supporting function from the traditional guide panel and relocates it to the cover bottom. The cover bottom includes supporting protrusions that extend into the cavity to support the liquid crystal display panel, while the guide panel is removed or reduced in size, thereby reducing the bezel area while maintaining structural stability.
Solution Approach 2:
The invention changes the spatial arrangement by moving the supporting function from a lateral structure (guide panel at the edge) to a vertical structure (supporting protrusions extending from the cover bottom into the cavity). This dimensional change allows the support function to be achieved without occupying additional bezel area.
2Strength
If the guide panel is coupled with the cover bottom and liquid crystal display panel, then structural support is improved, but the device complexity increases
Solution Approach 1:
The invention merges the supporting function into the cover bottom by integrating supporting protrusions directly into the cover bottom structure. This eliminates the need for a separate guide panel component and its associated coupling mechanisms, thereby reducing device complexity while maintaining structural support strength.
Solution Approach 2:
The cover bottom is designed to perform multiple functions: it provides structural support through its rigid construction, maintains the distance between optical sheets via supporting protrusions, and supports the liquid crystal display panel. This multi-functionality eliminates the need for separate dedicated supporting components, reducing overall device complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively decreases the bezel area, enhancing the perceived screen size by minimizing the space occupied by the supporting structures, thus increasing the effective display area.
Implementation Method 1
the light guide plate converts linear light or point light emitted from the light sources into planar light and causes the planar light to travel to a front surface of the liquid crystal display
Implementation Method 2
a reflective sheet for reflecting light reflected to a lower part of the light guide plate to a front surface of the light guide plate
