Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional backlight modules for liquid crystal display devices lack efficient independent light control, leading to increased power consumption and potential light interference between light emitting components.
Innovation Solution
A light source with a substrate featuring a first and second light emitting component, separated by a reflective structure, allowing for independent light emission into distinct regions within a light guide plate, enabling simultaneous or selective operation to reduce power consumption and prevent light interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light emitting components are used in a backlight module, then the illumination coverage is improved, but light interference between components occurs and power consumption increases
Solution Approach 1:
The backlight module is segmented into multiple independent light emitting regions, each with its own light emitting component and light guide plate. The first light guide plate and second light guide plate are physically separated and do not overlap, allowing each component to emit light independently without interference. This segmentation enables the use of multiple light emitting components while preventing the harmful light interference that would occur in a unified structure.
2Illumination intensity
If multiple light emitting components are used to increase illumination coverage, then the lighting area is improved, but power consumption increases
Solution Approach 1:
The backlight module divides the lighting area into multiple independent regions, each served by a separate light emitting component. This allows selective activation of individual light emitting components based on display needs, enabling the system to achieve comprehensive illumination coverage while consuming less power by activating only the necessary regions rather than all components simultaneously.
Solution Approach 2:
The control system dynamically manages the operation of different light emitting components based on actual display requirements. By selectively activating or deactivating specific light emitting components and their corresponding light guide plates, the system adapts the power consumption to the actual lighting needs, achieving energy efficiency while maintaining adequate illumination coverage.
3Device complexity
If a unified light guide plate structure is used, then the structure is simple, but light interference between components cannot be prevented
Solution Approach 1:
Instead of using a single unified light guide plate, the invention segments the light guide structure into multiple separate light guide plates (first light guide plate and second light guide plate). Each light guide plate is associated with a specific light emitting component and directs light independently. This segmentation prevents light interference between components while maintaining relatively simple individual structures, as each light guide plate operates independently without complex light isolation mechanisms.
