Solution Overview
Problem
The challenge of arranging ambient light sensors in electronic devices with large screen-to-body ratios, which affects display regions and requires complex software processing and additional painting to conceal components, is addressed.
Innovation Solution
The ambient light sensor is positioned within a cavity of the electronic device, with the ambient light sensor, the transparent cover plate and the first subregion, the ambient light sensor, the ambient light sensor is positioned within a side of the electronic device, allowing external light to pass through a non-light-emitting first subregion of the display module, simplifying software processing and reducing the need for additional painting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the ambient light sensor is arranged on the display screen with large screen-to-body ratio, then the display region is maximized, but the sensor arrangement is limited and requires additional painting to conceal components
Solution Approach 1:
The ambient light sensor is moved from the traditional front display area to the side surface of the electronic device. This spatial relocation allows the sensor to receive ambient light through the side surface while maintaining a large front display area, eliminating the need for black painting on the display screen and simplifying the manufacturing process.
2Measurement precision
If the ambient light sensor is positioned to detect external light through the display module, then software matting algorithms are required for processing, but this increases computing complexity
Solution Approach 1:
The ambient light sensor is extracted from the traditional position behind the display module and relocated to the side surface. This extraction allows the sensor to directly detect external ambient light without interference from display module components, eliminating the need for complex software matting algorithms and reducing computing complexity.
3Ease of manufacture
If the first subregion is designed with light transmittance to allow external light passage, then all functional layers do not need to be removed, but this requires precise control of light transmittance properties
Solution Approach 1:
The side surface of the electronic device is designed with specific light transmittance properties to allow ambient light to reach the sensor. This localized optical property control on the side surface enables light passage without requiring removal of display functional layers, maintaining manufacturing ease while achieving the desired optical effect.
