Transparent Mold Unit for Narrow Bezel LCD Panel Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LCD devices face challenges in achieving a slim structure and stable fixation of the display panel due to the reduction in bezel size, leading to potential separation of the display panel from the device.
Innovation Solution
A display device design incorporating a transparent mold unit coupled to a top chassis, which includes a protrusion and a coupling unit, and a black printing layer on the top chassis to securely fix the display panel while forming a narrow bezel, using a combination of a base unit and a coupling unit with different thicknesses to stabilize the panel.

If the size of the top chassis is reduced to achieve a narrow bezel, then the bezel width is reduced, but the display panel becomes easily separated from the display device
Solution Approach 1:
The top chassis is divided into multiple components: a first chassis member with a first protrusion and a second chassis member with a second protrusion. These segmented parts work together to provide sufficient fixation force for the display panel while maintaining a reduced overall bezel width, resolving the contradiction between compact size and reliable panel attachment.
Solution Approach 2:
The mold unit is inserted into a corresponding cavity in the top chassis, creating a nested structure. This nesting arrangement allows the mold unit to be securely held within the reduced-size top chassis, providing stable panel fixation without increasing the external dimensions of the bezel.
2Shape
If the top chassis size is reduced to form a narrow bezel, then the aesthetic appearance is improved, but the structural integrity for fixing the display panel deteriorates
Solution Approach 1:
The top chassis incorporates localized protrusions (first and second protrusions) that concentrate the fixation function in specific areas. This local quality enhancement allows the overall chassis to remain compact with a narrow bezel while providing sufficient local strength and grip to securely fix the display panel.
Solution Approach 2:
The top chassis is formed by combining multiple materials or components (first chassis member, second chassis member, and mold unit) to achieve a composite structure. This composite approach enables the maintenance of structural strength for panel fixation while reducing the overall size and forming a narrow bezel configuration.

AI summary
A display device includes: a display panel having a display area and a non-display area; a light source configured to supply light to the display panel; a bottom chassis on which the light source is disposed; a top chassis coupled to the bottom chassis and not covering an edge portion of the display panel; and a mold unit coupled to the top chassis and covering the edge portion of the display panel, wherein the mold unit may be transparent.
