Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production cost of backlight modules increases due to the need for a separate production jig and wiring process when lighting an independent backlight module, as existing methods require synchronization with a system on chip (SOC) board for timing control.
Innovation Solution
A backlight module design that includes a control circuit, power chip, and light emitting components, where the control circuit receives multiple power signals to generate an enable signal for the power chip, allowing independent lighting without external SOC connection, thus eliminating the need for a separate production jig and wiring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the backlight module is controlled separately from the SOC board, then the production cost increases due to the need for a separate production jig and wiring process, but the backlight module can be independently tested and assembled
Solution Approach 1:
The patent merges the control circuit directly into the backlight module, combining the previously separate control function with the backlight module. This integration eliminates the need for external production jigs and complex wiring, allowing the backlight module to be independently tested and assembled while reducing overall system complexity.
Solution Approach 2:
The control circuit within the backlight module enables the module to control its own lighting operations independently. The control circuit receives control signals and directly manages the light emitting components, allowing the backlight module to serve itself without requiring external SOC board intervention during assembly and testing phases.
2Manufacturing precision
If the backlight module is synchronized with the SOC board for timing control, then the lighting timing is precisely controlled, but the production process becomes more complex and costly
Solution Approach 1:
The control circuit is integrated into the backlight module itself, merging the timing control function with the lighting control. This eliminates the need for a separate synchronization system with the SOC board, reducing device complexity while maintaining precise lighting timing control through the integrated control circuit's ability to process control signals independently.
3Ease of operation
If a separate production jig is used for lighting the backlight module, then the lighting process can be controlled, but the production cost increases
Solution Approach 1:
The control circuit is integrated directly into the backlight module, merging the lighting control function with the module itself. This eliminates the need for a separate production jig, reducing production cost while maintaining full lighting control capability through the integrated control circuit that can process control signals independently.
Solution Approach 2:
The backlight module with its integrated control circuit can control its own lighting operations without requiring external production jigs. The control circuit independently manages the lighting states based on received control signals, enabling the module to be self-sufficient during assembly and testing, thereby reducing production costs.
