Abstract

The invention provides a touch display screen with a fingerprint identification device, which is characterized in that the touch display screen is a liquid crystal display screen, the liquid crystal display screen comprises a fingerprint sensing unit and a control circuit integrated in a thin film transistor layer of the liquid crystal display screen, wherein the fingerprint sensing unit is used for collecting light entering the touch display screen and converting the collected light into an electric signal; the light ray is the reflected light ray generated after the screen light source is blocked by the fingerprint; the control circuit is configured to convert the electrical signal generated by the fingerprint sensing unit into an image signal according to a matching algorithm and generate a fingerprint image. The invention can integrate the fingerprint identification area under the display area of the touch display screen, and does not need to add a separate fingerprint identification module, thus improving the integration level of the equipment and reducing the production and design cost.

Description

technical field [0001] The invention relates to the technical field of touch display, in particular to a touch display screen with a fingerprint identification device. Background technique [0002] With the popularization and development of mobile payment, fingerprint recognition has gradually become an important password verification method in mobile payment. Therefore, for existing mobile devices, especially mobile phones, the fingerprint identification device is an indispensable and alternative component. How to set the position of the fingerprint identification device on the terminal so as to further improve the convenience of use and optimize the user experience has become one of several important issues to be considered when designing a mobile phone. [0003] At present, the fingerprint identification devices of most mobile devices are installed on the non-display area of ​​the mobile device, such as the back of the display screen, or on the non-display area of ​​th...
