The electronic device includes: a power supply and a display screen in the above embodiments.

The display screen is electrically connected with a power supply, and the power supply is used for supplying power to the display screen.

Of course, the electronic device may also have a processor, and the display screen is electrically connected to the processor, and displays the content information according to the instruction of the processor.

The polymer lithium battery can be selected to be 6V, and the embodiment is not limited to the above 3 voltages, and the corresponding voltage and voltage stabilizing module can be selected according to the requirement.

The electronic device may be equipped with a fingerprint authentication mechanism to improve the security of the access device. Fingerprint sensing is useful in mobile applications and other applications that use or require secure access. For example, fingerprint sensing may be used to provide secure access to mobile devices and secure financial transactions including online purchases. It is desirable to include robust and reliable fingerprint sensing suitable for mobile devices and other applications. In mobile, portable or wearable devices, it is desirable for the fingerprint sensor to minimize or eliminate the occupancy of fingerprint sensing due to the limited space on these devices, especially in view of the need for maximum display area on a given device.

The light generated by the display screen for displaying an image must pass through the first side 21 of the cover plate 20 in order to be seen by the user. A finger may touch the first side 21 of the cover sheet 20 to interact with the light at the top surface, such that the reflected or scattered light at the touched surface area carries the spatial image information of the finger and returns to the display panel 10. In touch sensing display devices, the top surface is the touch sensing interface that interfaces with the user, and this interaction between the light used to display the image and the user's finger or hand occurs constantly, but this information-carrying light that returns to the display panel 10 is largely wasted and is not used in most touch sensing devices. In various mobile or portable devices with touch sensing display and fingerprint sensing functionality, the fingerprint sensor is typically a device separate from the display screen, either disposed on the same surface as the display screen outside the area of the display screen, or disposed on the back of the smartphone, to avoid taking up valuable space on the front for placing a large display screen.

These fingerprint sensors are devices that are separate from the display screen and thus need to be compact to save space for display and other functions while still providing reliable and fast fingerprint sensing with a spatial image resolution above some acceptable level. However, because high spatial image resolution in acquiring fingerprint images based on various suitable fingerprint sensing technologies (e.g. capacitive touch sensing or optical imaging) requires a large sensor area with a large number of sensing pixels, the need for compact compactness and the need to provide high spatial image resolution when acquiring fingerprint patterns directly conflict with each other in many fingerprint sensors.

The electronic device may also include an optical sensor module that uses light from the display screen at least in part as illumination probe light, illuminates a fingerprint sensing area on a touch sensing surface of the display screen, and performs one or more sensing operations based on optical sensing of this light. The display screen may be based on a variety of display technologies or configurations, including a display screen having light-emitting display pixels without the use of a backlight, wherein each individual pixel generates light for forming a display image on the display screen.

For example, if the display panel 10 of the present invention is an LCD screen, integrating optical sensing into the LCD, the optical sensor under the LCD may be used to detect a portion of the light used to display an image in the LCD screen, wherein the light used for the display screen may be scattered light, reflected light, or some stray light. In some implementations, the image light of the backlight-based LCD screen may be reflected or scattered back into the LCD display as return light when encountering a target such as a user's finger or palm, or a user pointer device like a stylus. This returned light may be collected for performing one or more optical sensing operations using the disclosed optical sensor technology. Due to the use of light from the LCD screen for optical sensing, the optical sensor module can be integrated into the LCD display screen in a manner that maintains the display operation and functionality of the LCD display screen without interference, while providing optical sensing operation and functionality to enhance the overall functionality, device integration, and user experience of electronic devices or systems such as smartphones, tablets, or mobile/wearable devices.
