Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection apparatuses can only support one color gamut standard and lack the ability to dynamically adjust color gamuts, limiting their versatility across different applications.
Innovation Solution
A light source system comprising a first blue laser light source, a red laser light source, a green laser light source, a second blue laser light source, and a wavelength conversion element, controlled by a controller to dynamically adjust the color gamut by turning on or off these sources and adjusting their power proportions, allowing for the combination of blue, red, green, and excited light to form light source light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a projection apparatus is designed to support only one color gamut standard, then the device structure can be simplified, but the adaptability to different color gamut requirements is reduced
Solution Approach 1:
The projection apparatus is designed with a universal light source system that can support multiple color gamut standards (DCI, Rec. 2020, and other custom gamuts) through a single device configuration. The system uses multiple laser light sources (blue, cyan, green, yellow, red) that can be selectively combined to achieve different color gamuts, making the device adaptable to various application scenarios without requiring separate projection apparatus for each standard.
Solution Approach 2:
The light source system implements dynamic color gamut adjustment by controlling the intensity ratios of different laser light sources through a controller. The system can dynamically switch between different color gamut standards and even create custom gamuts by adjusting the power proportions of individual laser sources, enabling real-time adaptation to different content requirements and display scenarios.
2Adaptability or versatility
If multiple laser light sources are used to achieve dynamic color gamut adjustment, then the color gamut versatility is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple laser light sources (blue laser, cyan laser, green laser, yellow laser, red laser) into a single integrated light source system. These individual laser sources are merged through optical components and controlled by a unified controller that adjusts their intensity ratios, allowing the system to achieve multiple color gamuts while managing the complexity through integrated design rather than separate systems.
