Problems solved by technology

In the daytime or in a well-lit environment, users can easily find the fingerprint identification area for fingerprint operation, but when it is dark and there is no light or insufficient light, it is difficult for the user to accurately find the fingerprint identification area, which reduces the fingerprint identification. Success rate

Embodiment 2

[0063] The same content in the second embodiment as in the first embodiment will not be repeated here.

[0064] Figure 4 It is a cross-sectional view of the fingerprint identification device of the third embodiment of the present invention. Figure 4 The fingerprint identification device 3 of the third embodiment shown figure 2 The difference of the fingerprint identification device 1 of the first embodiment shown is that the fingerprint identification device 3 does not include the protective layer 18 and the frame 17.

Embodiment 3

[0067] The same content in the third embodiment as in the first embodiment will not be repeated here.

[0068] The fingerprint identification device disclosed in the present invention can be integrated into the touch screen or housing of a terminal device such as a smart phone or a tablet computer. For example, it can be used in combination with the control button or switch element of the terminal device, or it can be directly embedded in the cover glass or shell of the terminal device and used alone. In short, it is possible to make adaptive adjustments according to the situation of the terminal equipment to facilitate the use of users. When the fingerprint identification device is used in combination with the control button or switch element of the terminal device, a pressure sensitive element needs to be provided under the fingerprint identification device to sense the user's pressing operation when operating the control button or switch element.

Abstract

The invention discloses a fingerprint recognition device and a terminal device. The fingerprint recognition device comprises a circuit board, a fingerprint recognition assembly, at least one light emitting module and a molding layer, wherein the fingerprint recognition assembly is located on the circuit board and electrically connected with the circuit board, the fingerprint recognition assembly comprises a substrate, sensors formed on the top surface of the substrate and a control chip, and the control chip is installed on the bottom surface of the substrate in a flip chip mode and electrically connected with the sensors; the light emitting modules are located on the circuit board and electrically connected with the circuit board; the molding layer is formed on the circuit board, and the space among the circuit board, the fingerprint recognition assembly and the at least one light emitting module is filled with the molding layer.

Description

Technical field [0001] The present invention relates to the field of biological identification, and in particular to a fingerprint identification device with a built-in light-emitting component and a terminal device containing the fingerprint identification device. Background technique [0002] In recent years, with the development of storage technology, terminal devices such as smart phones, tablet computers, etc. store a large amount of important data such as personal information, and their security has become more important. At present, passwords, graphics, and other forms are often used to achieve password protection for their terminal devices. [0003] However, for passwords, graphics and other encryption methods, users need to remember the set passwords and / or graphics; in addition, in public places, there is a risk of password leakage. In order to improve security, it is often necessary to increase the complexity of passwords and graphics, which undoubtedly further increase...
