Backlight Module Inward Carrying Portion for Narrow Border Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backlight modules for display devices have a wide mold frame structure that does not meet the design requirements of narrow border display devices, limiting the ability to reduce the frame width without compromising the holding capacity of the display panel.
Innovation Solution
A backlight module design featuring a back plate with a sidewall and a first carrying portion that extends inwardly from the sidewall, allowing the display panel to be securely held without increasing the frame width, utilizing a notch in the optical film to receive the carrying portion and enhance panel support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional mold frame structure is used to hold the display panel, then the display panel can be securely held, but the frame width becomes too wide, not meeting the narrow border design requirement
Solution Approach 1:
The mold frame is divided into two functional parts: a first carrying portion that extends inward from the sidewall to provide the primary holding function, and a second carrying portion near the light source that provides additional support. This segmentation allows each part to be optimized independently, reducing the overall frame width while maintaining holding capacity.
Solution Approach 2:
The first carrying portion extends inward from the sidewall in a direction perpendicular to the light guide plate, creating a three-dimensional structure that provides holding capacity without increasing the horizontal frame width. This dimensional change allows the frame to maintain narrow borders while still securely holding the display panel.
2Length of stationary object
If the frame width is reduced to meet narrow border requirements, then the aesthetic design is improved, but the holding capacity and reliability of the display panel decreases
Solution Approach 1:
The first carrying portion is nested within the sidewall structure, extending inward to provide holding function without increasing the external frame dimensions. This nesting approach allows the holding mechanism to be contained within the existing frame boundary, maintaining narrow borders while ensuring reliable panel support.
Solution Approach 2:
The carrying portions are strategically positioned at specific locations (one away from the light source and one near the light source) rather than uniformly distributing the frame structure. This local quality approach provides enhanced holding capacity at critical positions while keeping the overall frame width narrow.

AI summary
A backlight module is provided. The backlight module includes a back plate, at least one first carrying portion, a light guide plate, at least one optical film and a light source. The back plate has a sidewall. The first carrying portion is disposed on the back plate. The light guide plate is disposed on the back plate. The optical film is disposed above the light guide plate, in which the optical film has a notch which is corresponding to the first carrying portion. The light source is disposed on the back plate, in which the light source is disposed adjacent to a light-incident surface of the light guide plate.
