Solution Overview
Problem
Conventional sensors in electronic devices occupy valuable space on the main board, leading to a low utilization rate of the board area.

Integrating sensors within a display layer of the electronic device, where the sensors are located inside a light transmitting layer and capture ambient light, allowing them to operate without occupying main board space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are arranged on the main board, then the electronic device can capture ambient light, but the main board area utilization rate decreases
Solution Approach 1:
The patent merges the sensor with the display structure by integrating the sensor into the display assembly. The sensor is positioned behind the display screen, allowing it to share the display's spatial footprint. This combining approach enables the sensor to capture ambient light while the display occupies the front surface area, thus resolving the contradiction between maintaining sensing function and maximizing main board area utilization.
Solution Approach 2:
The patent transitions the sensor from a two-dimensional placement on the main board to a three-dimensional integration within the display assembly. By positioning the sensor in the Z-dimension (behind the display screen rather than on the main board plane), the solution eliminates the conflict for two-dimensional space while preserving the sensing capability.
2Area of stationary object
If sensors are integrated inside the light transmitting layer, then main board area utilization increases, but light capture efficiency may be affected
Solution Approach 1:
The patent applies local quality by creating a specific region in the display assembly where the sensor is positioned. The light transmitting layer is designed with localized optical properties that favor light transmission to the sensor's position. This localized optimization ensures that while the sensor is integrated within the display structure, it still receives sufficient ambient light for accurate sensing.
Solution Approach 2:
The light transmitting layer acts as an intermediary between the external ambient light and the sensor. This intermediate structure facilitates light transmission from the front surface to the sensor positioned behind it, ensuring that the sensor can capture light effectively despite being integrated within the display assembly rather than placed directly on the main board.
