Backlight Module Plastic Frame and Source Carrier Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backlight modules require disassembly for component testing and replacement, leading to low efficiency and potential damage to non-faulty components, resulting in high labor costs and time consumption.
Innovation Solution
A rearranged backlight module structure featuring a plastic frame combined with a strip-shaped source carrier and printed circuit board, where the source carrier includes holes for light transmission and is connected to the plastic frame via a groove and bump system, allowing for easier assembly and disassembly, and a light-block bar reduces lateral light leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the backlight module is designed as integration with PCB fixed on plastic frame and light guide plate, then the structure is compact and stable, but it becomes inevitable to take the backlight module apart to check and replace components, resulting in extremely low maintenance efficiency
Solution Approach 1:
The backlight module is divided into independent functional modules: the light source assembly (PCB with LEDs) is separated from the plastic frame and light guide plate. This segmentation allows the light source module to be independently removed and replaced without disassembling the entire backlight module, resolving the contradiction between structural stability and ease of repair.
2Measurement precision
If detailed test is required to detect faulty components in integrated backlight module, then the diagnosis is thorough, but it takes a lot of time and costs a lot of labor power
Solution Approach 1:
By segmenting the light source as an independent module, the fault detection process is simplified. Instead of testing each component individually in an integrated structure, the entire light source module can be quickly identified and replaced as a unit, maintaining diagnostic accuracy while dramatically reducing time and labor costs.
3Device complexity
If the conventional integrated structure is used, then the assembly is compact, but the efficiency of production and maintenance is extremely low
Solution Approach 1:
The light source assembly is designed as a separate modular unit that can be independently manufactured and assembled. This modular approach increases production efficiency by allowing parallel manufacturing of different components and simplifying quality control, while maintaining a compact final assembly.

AI summary
The present disclosure proposes a backlight source of a backlight module. The backlight source includes: one or more strip-shaped source carrier, comprising a plurality of holes arranged on a light emitting surface; the source carrier combined with the plastic frame; the source carrier and the plastic frame enclosing a rectangular frame; a PCB, arranged on the source carrier; and a source, corresponding to the hole and arranged on the source carrier; the source connected to the printed circuit board and transmitting light into the backlight module from the hole. The combination of the plastic frame and the backlight source realizes the respective functions of the conventional plastic frame and the conventional backlight source. Owing to the simplified plastic frame and backlight source, the bezel of the display can be narrower and smaller to satisfy the demands for the display with a narrow bezel.
