Dual Display Module Light Source Integration on PCB
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing dual display module manufacturing process is complex and costly due to the need for aligning and electrically connecting independent light sources into light bars, which complicates the assembly and increases production expenses.
Innovation Solution
The dual display module design integrates light sources directly onto a printed circuit board (PCB), eliminating the need for light bars and simplifying the assembly process by directly fixing the light sources onto the PCB, thereby reducing manufacturing complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If light sources are disposed on a flexible substrate to form light bars, then the light sources can be positioned and electrically connected, but the manufacturing process becomes complex and costly with increased assembly time
Solution Approach 1:
The patent merges the light source mounting substrate with the circuit board into a single integrated structure. The circuit board serves dual functions as both the electrical connection substrate and the light source mounting platform, eliminating the need for separate light bar assemblies and reducing manufacturing complexity
Solution Approach 2:
The circuit board is designed to perform multiple functions: providing electrical connections for display modules, serving as a structural support, and acting as the mounting substrate for light sources. This multi-functional design eliminates the need for separate light bar components and simplifies the overall manufacturing process
2Length of moving object
If light bars are used to hold light sources, then the light sources can be electrically connected and positioned, but the display module thickness increases
Solution Approach 1:
The patent combines the light source mounting function directly into the circuit board structure, eliminating the need for separate light bar components. This integration reduces the overall thickness of the display module while maintaining the ability to properly position and electrically connect light sources
3Ease of manufacture
If light sources are disposed on a flexible substrate, then the light bar structure is formed, but manufacturing materials and processes are increased
Solution Approach 1:
The circuit board is designed to serve multiple functions including structural support, electrical connections, and light source mounting. This eliminates the need for separate light bar structures and reduces the total material requirements for the display module
Solution Approach 2:
The patent merges the functions of the flexible substrate and circuit board into a single rigid circuit board structure that performs both electrical and mechanical mounting functions, reducing the number of components and materials needed
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach streamlines the manufacturing process, reduces assembly time and costs, and allows for a thinner display module design by eliminating the need for light bars and their associated alignment and connection steps.
Implementation Method 1
a first light source (204a) disposed in the housing (201) and adapted to provide light to the first display module (20a); a second light source (204b) disposed on the printed circuit board (206) and adapted to provide light to the second display module (20b)
Implementation Method 2
the first display module 15 and the second display module 17 are disposed at both sides of a reflective plate 105 respectively, so that the reflective plate 105 reflects light from the light bars 106a, 106b to improve the light emergence percentages of the first display module 15 and the second display module 17
