Backlight Module Widening Member for Common Mold Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and complexity of manufacturing on-board display screens with different appearance sizes for vehicles with the same visual area size, due to the need for specialized backlight molds, result in increased production costs and difficulty in control.
Innovation Solution
A backlight module with a backboard and an outer frame that includes a widening member detachably connected to the outer frame, allowing for adjustable width adjustments, enabling the use of a common mold for the outer frame and reducing the number of molds required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If specialized backlight molds are made for each appearance size, then the display screen can meet various customization requirements, but the manufacturing cost increases and control becomes more difficult
Solution Approach 1:
The backlight module is segmented into a standard outer frame and detachable widening members. The outer frame maintains a fixed standard size, while the widening members are separate components that can be added or removed to achieve different appearance sizes. This segmentation allows the standard outer frame to be reused across multiple products, reducing mold costs while still providing customization capability through different combinations of widening members.
Solution Approach 2:
The outer frame is designed with universal applicability, serving as a common component for multiple display screen configurations. By making the outer frame standardized and detachable from the widening members, a single outer frame mold can produce frames that fit various appearance sizes when combined with different widening members, thus achieving multi-functionality and reducing the number of specialized molds needed.
2Adaptability or versatility
If specialized backlight molds are made for each appearance size, then the display screen can meet various customization requirements, but the device complexity increases
Solution Approach 1:
The backlight module structure is divided into standardized outer frame and detachable widening members. This segmentation simplifies mold management by reducing the number of specialized molds needed - only one standard outer frame mold is required, while widening members can be produced with simpler molds. The modular structure makes it easier to manage and track molds compared to having specialized molds for each complete appearance size configuration.
Solution Approach 2:
The standardized outer frame serves multiple functions across different display configurations, reducing the total number of molds that need to be manufactured, stored, and managed. This universal component approach simplifies mold management infrastructure and reduces the complexity of tracking and maintaining multiple specialized molds for different appearance sizes.

AI summary
The present disclosure provides a backlight module and a display panel, wherein the backlight module includes a backboard and a widening member, the widening member is disposed on at least one side of the outer frame opposite to the accommodation chamber and detachably connected to the outer frame. As such, when on-board display screens having a same visual area size but different appearance sizes are used, only the widening member needs to be changed to meet the requirements of the overall appearance size. The outer frame can be used in common, and thus a mold for the outer frame can be used in common, thereby significantly reducing the number of mold of the outer frame of the backlight module, and thereby reducing a cost of the backlight module.
