Problems solved by technology

In this traditional portable terminal with a touch screen, the keyboard lock is usually protrudingly arranged on the edge side of the portable terminal in the form of a button, so when the user grasps the portable terminal or unintentionally presses the keyboard lock, thereby driving the portable terminal and consuming the portable terminal. power
Moreover, since the keyboard lock is provided on the edge side of the portable terminal, it gives people a feeling of unevenness and irregularity, which reduces the appearance quality of the portable terminal.
At the same time, when the security is realized by inputting the password, the password must be input every time, so it is more troublesome, and the password is easily cracked to cause the security function to fail
[0004] Moreover, existing portable terminals can only realize fingerprint recognition in non-visible areas, and basically cannot realize fingerprint recognition in visible areas.

Embodiment 1

[0074] Such as Figure 1 to Figure 8 As shown, the touch screen with fingerprint identification function of the present invention includes a touch screen module A with a fingerprint identification area 3, a position sensor module B, a fingerprint identification module C, a radio frequency signal boost module D and signal processing modules connected to the above modules respectively Module E. Wherein, the fingerprint identification area 3 of the touch screen module A includes: a semiconductor layer 4 , a substrate 5 , a semiconductor composite layer 6 and a capacitive screen lead layer 7 .

[0075] The substrate 5 can be a transparent cover, such as glass or sapphire. The substrate 5 can take into account protection and can be penetrated by electric field lines of fingerprints.

[0076] refer to image 3 and 4 , the semiconductor layer 4 is formed on the substrate 5 , and the semiconductor layer 4 includes a pattern formed by a plurality of semiconductor leads 41 . Wherei...

Embodiment approach

[0094] When the user's finger touches the fingerprint identification area 3 in the touch screen 2 of the mobile phone 1, the first capacitive screen lead wire 61 and the second capacitive screen lead wire 71 detect the position of the finger, and send a signal to the position sensor module, and the position sensor module feedbacks to the signal processing unit. The signal processing unit switches off the signal generator / receiver in the position sensor. Then, the signal processing unit starts the radio frequency high-voltage module, and the radio frequency high-voltage current is delivered to the first capacitive screen lead wire 61 interspersed between the first drive electrode 62 and the second drive electrode 65 through the position sensor module, and the first capacitive screen lead wire 61 is connected to the first capacitive screen lead wire 61. The semiconductor lead 41 on the surface of the substrate 5 is coupled and charged, and the finger obtains a small radio freque...

Abstract

The invention discloses a touch control screen with a fingerprint recognition function and an electronic device with the touch control screen. The touch control screen comprises a substrate, a semi-conductor layer, a semi-conductor composite layer and a capacitive screen lead layer, wherein the semi-conductor layer is formed on the upper portion of the substrate and comprises a pattern formed by multiple semi-conductor leads; the semi-conductor composite layer is formed on the lower portion of the substrate and comprises a plurality of fingerprint recognition leads used for detecting fingerprint images and multiple first capacitive screen leads, the first capacitive screen leads are formed among the fingerprint recognition leads, and the first capacitive screen leads correspond to the pattern formed by the semi-conductor leads; the capacitive screen lead layer is formed on the lower portion of the semi-conductor composite layer and comprises multiple second capacitive screen leads, and the first capacitive screen leads and the second capacitive screen leads are distributed in a crossed mode. By means of the touch control screen, fingerprint recognition can be carried out on a transparent cover plate of a display area in a display screen, and the fingerprint recognition function is integrated with a touch circuit.

Description

technical field [0001] The invention relates to the field of fingerprint identification, in particular to a touch screen with a fingerprint identification function and an electronic device with the fingerprint identification function. Background technique [0002] With the wide application of portable terminals in people's daily life, the functions of the current portable terminals are becoming more and more powerful, and such diversified functions are convenient for users. However, while the portable terminal provides more convenience for the user, it carries too much private information. If the portable terminal is lost or stolen, the information is easily leaked because there is no relevant protection. cause inconvenience to users. Therefore, it is very necessary to do some security settings on the portable terminal. [0003] The security function of a traditional portable terminal with a touch screen is nothing more than setting software functions such as a keyboard lo...
