Front Bezel Sidewall for Easy LED Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method for replacing damaged light emitting diodes in a liquid crystal display's backlight source is cumbersome, requiring removal of the front bezel and backlight module, causing inconvenience to manufacturers and users.
Innovation Solution
A front bezel assembly with a sidewall that extends into the backlight module, allowing the backlight source to be mounted directly to the sidewall, facilitating easy removal and installation by exposing the display panel through a bezel opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the backlight source is fixed to the backboard, then the backlight source is securely positioned, but the replacement of light emitting diodes becomes troublesome and time-consuming
Solution Approach 1:
The front bezel is divided into a front wall and a sidewall, with the sidewall extending into the backlight module to form a separate mounting structure. This segmentation allows the backlight source to be mounted on the sidewall rather than the backboard, enabling easy removal of only the sidewall for LED replacement without removing the entire backlight module or front bezel.
Solution Approach 2:
The sidewall is extracted as a separate functional component from the front bezel, specifically designed to hold the backlight source. This extraction creates an independent access path to the backlight source, allowing technicians to remove and replace LEDs by detaching only the sidewall portion, thus simplifying the repair process.
2Shape
If the front bezel covers the backlight module, then the display device has a complete external appearance, but access to the backlight source for maintenance becomes difficult
Solution Approach 1:
The front bezel is segmented into a front wall for aesthetic coverage and a sidewall extending into the backlight module for functional access. This segmentation allows the front bezel to maintain its complete external appearance while the sidewall provides a dedicated access path to the backlight source for maintenance operations.
Solution Approach 2:
The sidewall acts as an intermediary structure between the front bezel and the backlight source. It provides a mechanical interface that allows the backlight source to be mounted and accessed through the front bezel assembly, facilitating maintenance while preserving the external appearance.
3Stability of the object's composition
If multiple components must be removed to access the backlight source, then the backlight source is securely integrated, but the replacement process becomes complex and labor-intensive
Solution Approach 1:
The mounting structure is segmented by creating a dedicated sidewall portion within the front bezel that independently holds the backlight source. This segmentation reduces the number of components that must be removed for backlight source access, simplifying the replacement process from multiple component removals to just the sidewall detachment.
Solution Approach 2:
The sidewall is pre-configured within the front bezel assembly to provide direct access to the backlight source mounting location. This preliminary arrangement of the sidewall structure eliminates the need for complex disassembly sequences, allowing technicians to access and replace the backlight source through a predetermined simple path.

AI summary
A front bezel assembly is adapted to cover a display panel and a backlight module of a non-self-luminous display device. The backlight module includes an optical module. The front bezel assembly includes a front bezel. The front bezel assembly includes a front wall disposed in front of the display panel and formed with a bezel opening to expose the same, and a sidewall extending rearward from the front wall into the optical module. A backlight source is mounted to the sidewall such that light emitted from the backlight source irradiates toward the display panel through the optical module.
