Problems solved by technology

High-end products or applications similar to capacitive fingerprint recognition require a pattern structure with a small sensor pitch, but reducing the sensor pitch will lead to a reduction in the capacitance of the pattern itself, which in turn will lead to a decrease in the sensitivity of the sensor, especially for The impact of capacitive fingerprint recognition is quite significant, making the capacitive signal volume too low to penetrate the thickness of the cover, resulting in sensor insensitivity to touch, or even touch failure, which limits the application of capacitive fingerprint recognition technology to a certain extent. develop

Abstract

The invention discloses a touch module and a display device. The first electrode and the second electrode are adjacent to each other and are electrically connected with each other. The compensation electrode is insulated from the second electrode. The sensing areas of the first electrode and the second electrode are increased. In this way, before touch control, touch control is carried out, a first capacitance value is arranged between the first electrode and the second electrode; a second capacitance value is arranged between the compensation electrode and the second electrode. Namely, the capacitance value before touch control is the sum of the first capacitance value and the second capacitance value. Compared with the prior art, the capacitor before touch control is only a first capacitance value coupled between the first electrode and the second electrode. According to the touch module, the capacitance value before touch is large, and the difference between the capacitance values generated after a user touches the touch module is not large, so that the variation of the capacitance value after touch can be increased by increasing the capacitance value before touch, and the touchsensitivity of the touch module is improved.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a touch module and a display device. Background technique [0002] With the continuous development of touch technology, people's requirements for touch performance are gradually increasing. High-end products or applications similar to capacitive fingerprint recognition require a pattern structure with a small sensor pitch, but reducing the sensor pitch will lead to a reduction in the capacitance of the pattern itself, which in turn will lead to a decrease in the sensitivity of the sensor, especially for The impact of capacitive fingerprint recognition is quite significant, making the capacitive signal volume too low to penetrate the thickness of the cover, resulting in sensor insensitivity to touch, or even touch failure, which limits the application of capacitive fingerprint recognition technology to a certain extent. develop.
