Solution Overview

Problem

Message indicators on terminals, such as mobile phones, exhibit inappropriate luminescence due to constant brightness values, which are not adjusted according to environmental conditions, leading to suboptimal visibility and user experience.

Innovation Solution

A method and device that dynamically adjust the luminescence parameters of message indicators based on environmental brightness, including brightness and color temperature, to ensure optimal visibility by acquiring environmental brightness and controlling the message indicator's illumination accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If the message indicator uses a constant brightness value, then the device structure is simple and energy consumption is low, but the visibility and user experience deteriorate under different environmental lighting conditions

Engineering Contradiction:
Improvebrightness of message indicatorVSAvoidadaptability to environmental lighting conditions
Core Design Contradiction:
Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by transitioning the message indicator from a static constant brightness state to a dynamic adaptive brightness state. The controller continuously adjusts the brightness of the message indicator based on real-time environmental light sensor data, allowing the indicator to automatically adapt to different lighting conditions (dark, dim, bright environments) without requiring manual user intervention.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements feedback through a closed-loop control system where the light sensor continuously monitors environmental brightness and feeds this information back to the controller. The controller processes this feedback and adjusts the message indicator brightness accordingly, creating a self-regulating system that maintains optimal visibility across varying environmental conditions.

Inventive Principle:
Principle #23Feedback

2Illumination intensity

If the message indicator brightness is increased to improve visibility in bright environments, then visibility improves, but energy consumption increases

Engineering Contradiction:
Improvevisibility of message indicatorVSAvoidenergy consumption of message indicator
Core Design Contradiction:
Illumination intensityVSUse of energy by moving object

Solution Approach 1:

The patent applies parameter changes by dynamically modifying the brightness parameter of the message indicator based on environmental conditions. The controller adjusts the brightness level (as a variable parameter) according to ambient light levels detected by the sensor, rather than maintaining a fixed high brightness setting. This allows the system to achieve adequate visibility while minimizing energy consumption in lower-light environments.

Inventive Principle:
Principle #35Parameter changes

3Temperature

If the message indicator uses constant luminescence parameters, then the control system is simple, but the color temperature appears inappropriate under different environmental conditions

Engineering Contradiction:
Improvecolor temperature of message indicatorVSAvoidcomplexity of luminescence control system
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent applies dynamics by making the color temperature of the message indicator dynamic rather than static. The controller adjusts the color temperature parameter in real-time based on environmental lighting conditions detected by the light sensor, allowing the indicator to present appropriate color characteristics (warmer or cooler tones) depending on the ambient environment, enhancing visual comfort and appropriateness.

Inventive Principle:
Principle #15Dynamics

AI summary

Disclosed are method and device for controlling luminescence, belonging to the field of display control technology. The method includes: acquiring an environmental brightness; determining a luminescence parameter of a message indicator arranged on a terminal based on the environmental brightness; and controlling the message indicator to illuminate based on the luminescence parameter. By acquiring the current environmental brightness and then adjusting the luminescence parameter of the message indicator based on the environmental brightness, the present invention solves a problem of irrational luminescence of the message indicator resulting from the luminescence parameter being a constant value in the prior art; allows the luminescence parameter to be dynamically adjusted based on the environmental brightness, so that the luminescence is matched with the environmental brightness, and thereby optimizing the luminescence of the message indicator under different cases and thus improving the user's experience.
