Embodiment Construction

[0078] As mentioned in the background, the existing optical fingerprint imaging system has a single function and its application is limited.

[0079] To this end, the present invention provides a new information detection and display device, which includes a sensor, a protective layer arranged above the sensor and a display screen arranged below the sensor, and the display screen performs optical fingerprinting on the sensor. As a light source for imaging. When the information detection and display device is used as a display device, the display screen provides a corresponding display function, and the display light of the display screen is transmitted through the transparent substrate in the sensor and the transparent area of ​​the optical fingerprint imaging array pixels to achieve the function of displaying information. Therefore, compared with the existing optical fingerprint imaging system, the optical fingerprint imaging device has the function of displaying information ...

Abstract

The invention relates to an information detection display device, detection method and display method of the information detection display device. The information detection display device comprises a sensor, a protective layer arranged on the sensor. The information detection display device further comprises a display screen located below the sensor; and the display screen is adopted as a light source when the sensor performs optical information detection. The information detection display device not only has an optical fingerprint imaging function and a finger touch control sensing function, but also has an information display function, and therefore, the application range of the information detection display device can be extended.

Description

technical field [0001] The invention relates to the field of optoelectronics, in particular to an information detection and display device, a detection method and a display method thereof. Background technique [0002] Fingerprint recognition technology is to collect the fingerprint image of the human body through the fingerprint sensor, and then compare it with the existing fingerprint imaging information in the system to judge whether it is correct or not, and then realize the technology of identity recognition. Due to its ease of use and the uniqueness of human fingerprints, fingerprint recognition technology has been widely used in various fields, such as security inspection fields such as public security bureaus and customs, building access control systems, and consumer products such as personal computers and mobile phones, etc. [0003] Fingerprint identification technology first requires the ability to perform fingerprint imaging. Fingerprint imaging technology is im...
