The first electrode lines 11 and the second electrode lines 21 are made of ITO material. The insulating layer 3 is made of insulating resin. ...

Embodiment 2

[0109] Implementation 1 was repeated, except that the line width of the first electrode lines 11 was 0.01 mm; the line width of the second electrode lines 21 was 0.01 mm. The distance between two adjacent first electrode lines 11 is 0.15 mm; the distance between two adjacent second electrode lines 21 is 0.15 mm. The first electrode lines 11 and the second electrode lines 21 form an angle of 90° with each other, that is, they are perpendicular.

[0110] Taking 5 inches as an example, the size of the viewing area is 62.1mm*110.4mm, the distance between the receiving electrode and the emitting electrode is 0.15*0.15mm, and the width of a single metal wire is 0.01mm. (414) + emitter (736), the sum of the two requires a total of 1150 PADs (pins), and the metal lead is pulled down to the bottom of the glass to connect the processing chip.

Embodiment 3

[0112] Embodiment 1 was repeated, except that the line width of the first electrode lines 11 was 0.005 mm; the line width of the second electrode lines 21 was 0.002 mm. The distance between two adjacent first electrode lines 11 is 0.08 mm; the distance between two adjacent second electrode lines 21 is 0.06 mm. The first electrode lines 11 and the second electrode lines 21 form an angle of 90° with each other, that is, they are perpendicular.

[0113] Taking 5 inches as an example, the size of the visible area is 62.1mm*110.4mm, the distance between the receiving electrode and the emitter electrode is 0.08*0.06mm, the width of a single first electrode metal wire is 0.05mm, and the width of a single second electrode The width of the electrode metal wire is 0.002mm, and the visible area requires a total of receiving electrodes (776) + emitters (1833). The sum of the two requires a total of 2609 PADs (pins). Pull the metal leads down to the bottom of the glass and connect the proc...

Abstract

The invention provides a touch control and fingerprint identification module, a manufacture method thereof, and an electronic terminal. The touch control and fingerprint identification module includes a first electrode layer, a second electrode layer, a processing chip, and an insulating layer as a spacing layer between the first electrode layer and the second electrode layer. The first electrode layer, as a first electrode layer of fingerprint identification and touch control, comprises a plurality of successively arranged first electrode lines. The second electrode layer, as the second electrode layer of fingerprint identification and touch control, comprises a plurality of successively arranged second electrode lines. The first electrode lines of the first electrode layer and the second electrode lines of the second electrode layer are arranged in a staggered way and are connected to the processing chip. The processing chip processes signals from the first electrode lines and / or the second electrode lines to obtain a fingerprint and / or touch position. The touch control and fingerprint identification module can save the key fingerprint module space of a conventional touch device, integrates a touch control function and a fingerprint identification function, and is more convenient in operation and higher in security performance.

Description

technical field [0001] The invention relates to the field of human-computer interaction technology, in particular to a touch and fingerprint identification module, a preparation method thereof, and an electronic terminal. Background technique [0002] Fingerprints are lines formed by the uneven skin on the surface of the finger, which are composed of various ridges and grooves. The fingerprint feature is the smooth texture pattern composed of ridges and grooves on the surface of the finger, which is very random, and the fingerprint feature has the characteristics of uniqueness and stability, and identity recognition can be realized accordingly. [0003] Capacitive fingerprint recognition uses the different distances between the valleys and ridges of the fingerprint road and the capacitor to produce different capacitance changes to form a fingerprint pattern. The fingerprint feature value is extracted through software processing and compared with the pre-saved template featur...
