Solution Overview
Problem
Existing electronic devices face challenges in accurately sensing ambient light due to interference from the display screen's brightness, which affects the reliability of light detection and subsequent brightness control.
Innovation Solution
An electronic device design featuring a casing with a light sensing hole on the side, housing an ambient light sensor and optionally a light-converging or reflective structure, allows external light signals to be directly sensed without interference from the display screen, enhancing light sensing accuracy and brightness control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the ambient light sensor is disposed at one side of the display screen within the casing, then the device structure is compact and integrated, but the display screen brightness interferes with the ambient light sensing accuracy
Solution Approach 1:
The patent extracts the light sensing function from the main device body by providing a light sensing hole on the side surface of the casing. This allows the ambient light sensor to receive external light signals directly from outside the device, separating the sensing path from the display screen and eliminating the interference between display brightness and ambient light detection.
2Reliability
If the ambient light sensor receives light through the display screen, then the sensor is protected within the device, but the display screen brightness affects the sensing accuracy
Solution Approach 1:
The light sensing hole acts as an intermediary channel that allows external ambient light to reach the sensor without passing through the display screen. This intermediary structure enables the sensor to be protected within the device while simultaneously receiving accurate ambient light signals from outside, eliminating the interference caused by display brightness.
