Solution Overview
Problem
The challenge of signal wave energy reduction due to screen blocking in under-screen distance sensors, which hampers effective object detection outside electronic devices with full screens.
Innovation Solution
An electronic device design that utilizes a transmitter and receiver configuration, where the transmitter's transmitting end surface is in a high-transmittance region formed by the inner edge of the display screen, and the receiver's receiving end surface corresponds to a lower transmittance area, ensuring the transmitter, ensuring the transmitter's signal waves are not significantly attenuated, enabling long-distance object detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an under-screen distance sensor is used to detect objects outside the electronic device, then object detection capability is improved, but the screen blocks the transmitter when transmitting signal waves, greatly reducing the energy
Solution Approach 1:
The patent applies local quality by creating a first target region with higher transmittance properties at the location of the transmitter compared to other regions of the display screen. This is achieved by adjusting the optical properties of the display screen material or structure in the specific area where the transmitter is positioned, allowing signal waves to pass through with less attenuation while maintaining normal display functionality in other regions.
Solution Approach 2:
The patent changes the transmittance parameter of the display screen in the first target region to be greater than in the second target region. This parameter modification allows the transmitter to emit signal waves with sufficient energy to detect objects outside the electronic device, resolving the energy loss problem caused by the screen blocking the signals.
2Device complexity
If the transmitter is positioned behind the display screen, then the device maintains a full-screen design, but the screen structure blocks signal waves and reduces detection effectiveness
Solution Approach 1:
The patent maintains the full-screen design by positioning the transmitter behind the display screen while creating a local region (first target region) with enhanced transmittance properties. This allows the screen to appear full-screen from the user's perspective while enabling effective signal transmission in the specific area where the distance sensor operates.
Solution Approach 2:
The display screen itself acts as an intermediary element that is modified to have different transmittance properties in different regions. The first target region of the screen serves as a mediator that allows signal waves to pass through effectively while maintaining the overall full-screen structure and appearance.
