Button Backlight Color Matching via RGB Duty Cycle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing button backlights on terminal devices, such as mobile phones, are monotonous and only provide white light, failing to meet individualized user requirements for visual experience, especially in dark environments.
Innovation Solution
A method and apparatus that turns on button backlights using parameters corresponding to the current theme interface of the terminal device, utilizing RGB components to achieve color diversity by adjusting duty cycles of red, green, and blue LEDs, ensuring the backlight color matches or coordinates with the theme interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If white light backlight is used for buttons, then the button backlight function is achieved, but the visual experience is monotonous and cannot meet individualized user requirements
Solution Approach 1:
The patent changes the color parameter of the button backlight by adjusting the duty cycles of RGB LED components. Instead of using a fixed white light source, the system varies the intensity parameters of red, green, and blue LEDs to generate different colors that match theme interfaces, thereby achieving color diversity while using the same physical backlight structure.
Solution Approach 2:
The patent makes the button backlight system multi-functional by enabling it to serve both as a simple indicator light and as a thematic visual element. The same backlight hardware can adapt to different theme interfaces (dark mode, light mode, custom themes) by changing color parameters, making the backlight system versatile and adaptable to various user preferences and environmental conditions.
2Adaptability or versatility
If button backlight color is fixed to white, then the device structure is simple, but the visual appeal and personalization are limited
Solution Approach 1:
The system achieves theme matching by dynamically changing the duty cycle parameters of RGB LED components. When a theme interface is detected (dark mode, light mode, or custom theme), the controller adjusts the intensity parameters of each color component to generate the appropriate backlight color, enabling the button backlight to visually coordinate with the overall interface theme.
Solution Approach 2:
The button backlight transitions from a static white light source to a dynamic color-adaptive light source. The system continuously monitors the theme interface state and dynamically adjusts the backlight color parameters in real-time, making the backlight responsive and adaptive to changing interface themes and user preferences.
3Adaptability or versatility
If multiple color LEDs are added to achieve color diversity, then user personalization is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent merges multiple color LED components (red, green, blue) into a single integrated button backlight assembly. Instead of using separate backlight units for different colors, the system combines RGB LEDs in one compact structure, controlling them through a unified duty cycle adjustment mechanism, thereby achieving color diversity without proportionally increasing manufacturing complexity.
Solution Approach 2:
The system achieves multiple color options by changing the operational parameters (duty cycles) of existing RGB LED components rather than requiring separate physical LED assemblies for each color. This parameter-based approach allows the same hardware to provide multiple color outputs, significantly reducing manufacturing complexity compared to implementing separate backlight systems for each color option.
