Metal Back Bezel Display Module with Podium Structure for Light Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display modules with wider frame margins suffer from light leakage due to the proximity of the light guide plate to the display area, limiting the slim frame design and structural strength, and the use of plastic materials restricts further thickness reduction.
Innovation Solution
A display module design featuring a metal back bezel and frame body with strategically placed gaps for glue accommodation, allowing for a slim frame margin, enhanced structural strength, and improved light management by extending the backlight module outward, reducing light leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If the frame body thickness is reduced to achieve slim frame design, then the frame margin becomes narrower, but the distance between the light guide plate and display area decreases causing light leakage
Solution Approach 1:
The patent introduces a podium structure that extends in the depth direction (Z-axis) from the front surface of the frame body toward the backlight module. This dimensional extension creates additional space to increase the distance between the light guide plate and display area without increasing the overall frame thickness, thereby solving the light leakage problem while maintaining slim frame design.
Solution Approach 2:
The frame body is segmented into multiple functional regions: the main frame body, the podium structure extending from it, and the backlight module accommodation space. This segmentation allows each part to perform its specific function - the podium creates light isolation distance while the frame body maintains structural integrity and slim profile.
2Length of stationary object
If the frame body thickness is reduced to achieve slim frame design, then the frame margin becomes narrower, but the structural strength is compromised
Solution Approach 1:
The frame body is constructed using metal material (such as aluminum alloy) which provides high strength-to-weight ratio. This allows the frame to maintain adequate thickness for structural strength while achieving a slim overall appearance, overcoming the limitation of plastic materials.
Solution Approach 2:
The podium structure adds vertical dimension to the frame body design, creating a multi-level structure that enhances mechanical strength and stiffness without increasing the horizontal footprint or overall thickness perception, thus maintaining both slim design and structural integrity.
3Area of moving object
If the black frame area is reduced to increase display area, then the frame margin becomes narrower, but the space for accommodating backlight module is limited
Solution Approach 1:
The podium structure utilizes the depth dimension (Z-axis) to create accommodation space for the backlight module, rather than relying solely on horizontal or vertical plane expansion. This allows the backlight module to be positioned appropriately while maintaining a narrow frame margin and large display area.
Solution Approach 2:
The frame body is divided into the main horizontal frame structure and the vertical podium extension, creating distinct functional zones. The podium specifically accommodates the backlight module in the depth direction, separating the light source accommodation function from the display area, thereby maximizing both display size and backlight integration.
