Display Unit Adaptive Color Adjustment for Environmental Light
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing displays, such as LCDs, fail to adaptively change the displayed object's color characteristics in response to changes in environmental light, leading to a distorted user experience due to the inability to match the color expression with the surrounding environment.
Innovation Solution
An electronic device method that adjusts its display status by obtaining environmental parameters like color temperature, brightness, and chromaticity, simulating the corresponding characteristics of the displayed object, and recording adjustments to adapt the display settings, ensuring the displayed image aligns with the real-world appearance under varying environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display unit uses fixed color expressivity (e.g., 6-bit or 8-bit per primary color), then the color output is stable and controllable, but the displayed object cannot adapt to changes in environmental light, causing color distortion and degraded user experience
Solution Approach 1:
The patent implements dynamic display status adjustment by continuously monitoring environmental light conditions and automatically modifying display parameters. The processor adjusts color temperature, brightness, and chromaticity based on detected environmental changes, transforming the static display into a dynamic system that adapts to varying viewing conditions throughout the day
Solution Approach 2:
The system employs feedback mechanisms by detecting environmental light parameters and using this information to adjust display output. The display controller receives feedback about ambient lighting conditions and modifies color expressivity, brightness, and contrast settings accordingly, creating a closed-loop control system that maintains accurate color representation
2Measurement precision
If the display unit maintains consistent color expression across all conditions, then the display control is simple, but the displayed colors do not match the real-world appearance under different lighting conditions, leading to incorrect perception
Solution Approach 1:
The patent changes multiple display parameters simultaneously including color temperature, brightness, and chromaticity to match environmental lighting conditions. By adjusting these parameters dynamically, the display accurately reproduces how objects appear in different lighting scenarios, enhancing color precision and visual fidelity
3Quantity of substance
If the display unit increases color expressivity (e.g., using FRC technique with 8-bit per primary color), then each pixel can express more colors (16.7 million), but the display still cannot adapt to environmental light changes, causing the enhanced color capability to be wasted
Solution Approach 1:
The system dynamically utilizes the enhanced color expressivity by adjusting which color values are displayed based on environmental conditions. Rather than statically using all 16.7 million colors, the system adaptively selects and adjusts color expressions to match ambient lighting, making the high color capability meaningful and context-appropriate

AI summary
A method for an electronic device with a display unit and an electronic device are provided. The method may comprise: obtaining an environmental parameter under an environment where the electronic device is disposed when the display unit is in a first display status, the environmental parameter including at least an environmental color temperature parameter of the environment and configured for adjusting the display status of the display unit; determining whether to adjust the display status based on at least the environmental color temperature parameter included in the environmental parameter to get a first determination result; and adjusting the display status from the first display status to a second display status different from the first display status if the first determination result indicates that it is to adjust the display status.
