Sliding Sensor Module for Display Screen Brightness Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display screens with separate screen light and ambient light sensors require complex assembly processes, increasing labor, time, and costs, and reduce the available screen area due to sensor placement.
Innovation Solution
A sensor module with a slidable assembly that includes both sensors, allowing them to be conveniently mounted and switched between detecting screen brightness and ambient brightness, preventing coverage of the display area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screen light sensor and ambient light sensor are mounted on the frame in different positions, then both sensors can detect their respective targets, but the assembly process becomes complicated and demands more labor and time
Solution Approach 1:
The patent combines both the screen light sensor and ambient light sensor into a single sensor module that is mounted on the frame at one location. This merging of multiple sensors into one integrated module simplifies the assembly process while maintaining the detection functions of both sensors through a sliding mechanism that positions them appropriately.
Solution Approach 2:
The patent employs a sliding mechanism that allows the sensor module to dynamically switch between two positions: one where the screen light sensor detects screen brightness and another where the ambient light sensor detects ambient brightness. This dynamic positioning enables both sensors to function from a single mounted location, reducing assembly complexity.
2Measurement precision
If screen light sensor is disposed on the frame to detect screen brightness, then screen brightness can be detected, but the sensor partially covers the screen, thus reducing the available area of the screen
Solution Approach 1:
The patent extracts the screen light sensor from its conventional position on the frame and relocates it to a sliding mechanism that allows it to be positioned only when needed for detection. The sensor can be retracted or positioned in a way that minimizes or eliminates its coverage of the screen area, thus preserving more of the available screen space while maintaining detection capability.
Solution Approach 2:
The sliding mechanism enables the screen light sensor to dynamically adjust its position between an active detection position and a retracted position that does not cover the screen. This dynamic positioning allows the sensor to function when needed while maximizing the available screen area during normal display operation.

AI summary
A display screen with a display area includes a frame and a sensor module. The frame surrounds the display area. The sensor module is mounted on the frame and includes a mount disposed on the frame and a slidable assembly slidably disposed on the mount and including an ambient light sensor and a screen light sensor, wherein the ambient light sensor and the screen light sensor are disposed on two opposite sides of the slidable assembly respectively. When a side of the slidable assembly on which the screen light sensor is disposed faces the display area, the screen light sensor detects brightness of the display area. When the side of the slidable assembly does not face the display area, the ambient light sensor detects brightness of an ambiance.
