Electronic devices with display screens

Abstract

The present disclosure provides an electronic device with a display screen, and the electronic device with a display screen is used to obtain the user's physiological and / or pathological features by collecting the user's biological feature information. The electronic device with a display screen includes: a PPG light receiving unit for receiving light signals and converting the light signals into pulse wave signals; and a PPG acquisition unit for receiving and processing the pulse wave signals from the PPG light receiving unit to obtain user Physiological and / or pathological features, wherein the display screen is arranged such that the reflected part of the light emitted by the display screen to the first side can pass through the display screen to reach the second side opposite to the first side, and is arranged on the second side The PPG light-receiving units on both sides receive it, so that the electronic device with a display screen can collect the biometric information of the user based on the photoplethysmography method.

Description

technical field [0001] The present disclosure relates to an electronic device with a display screen, and the electronic device with a display screen can be used to obtain the user's physiological and / or pathological features by collecting the user's biological feature information. Background technique [0002] Wearable devices such as smart watches and wristbands, in addition to providing users with various functions as smart terminals, can also monitor the user's movement characteristics and even biometric characteristics through specific sensors, providing users with information ranging from time tracking to communication. A variety of health-related information, including time reporting, step counting, location, motion trajectory, heart rate or heartbeat detection, sleep tracking, and blood pressure monitoring, etc., especially health-related information, after corresponding processing, can be used to reflect the user's Physiological and / or pathological features, so that ...

Problems solved by technology

[0004] However, if the user's wrist is in motion when the user's biometrics are collected by these sensors, the credibility of the biometrics collected by the sensors may be affected, thereby affecting the credibility of the health-related information provided; in addition, The way the wearable device is worn on the user's wrist may prevent the sensor from obtaining proper contact with the measured area of ​​the wrist, so that the reliability of the sensor's collection of biometric characteristics may be affected, which also affects the reliability of the health-related information provided. degree

[0005] Therefore, the user's biometrics collected by existing wearable devices cannot be reliably used to obtain the user's physiological and / or pathological characteristics due to their insufficient reliability

[0006] On the other hand, for example, even for other electronic devices with display screens that can provide a dedicated location to set the PPG sensor, including mobile phones with PPG units (such as placing the PPG sensor on the back of the mobile phone), tablet computers (such as placing the The PPG sensor is placed on the back of the tablet computer), or even medical PPG measuring equipment (with a separate PPG sensor that can be clipped on the finger), although the degree of confidence can be obtained by properly placing the user's finger on the PPG sensor High biological characteristics, but the PPG sensor must contain a special PPG light-emitting unit, no matter from the perspective of product cost or product convenience, there is still room for further improvement of this existing electronic device
