Problems solved by technology

However, in the fingerprint sensor integrated capacitive touch screen, the mutual capacitance between the first channel electrode 111 and the second channel electrode 112 is significantly increased due to the second fine channel used as the touch channel 115.
According to the increase in mutual capacitance, the touch sensitivity of the fingerprint sensor integrated capacitive touch screen is degraded, making it impossible to perform touch recognition when a touch event is performed

Abstract

A touch sensing device comprises a plurality of first touch electrodes and a plurality of second touch electrodes located in an active area of the touch sensing device, the plurality of first touch electrodes and the plurality of second touch electrodes arranged in a first direction. The touch sensing device also includes a plurality of third touch electrodes located in the active area and arranged in a second direction that crosses the first direction. The first touch electrodes, second touch electrodes, and third touch electrodes have a first resolution for sensing touch in the active area. The touch sensing device also includes a plurality of combination touch and fingerprint electrodes located in the active area, the plurality of combination touch and fingerprint electrodes having a second resolution for sensing both touch and a fingerprint in the active area and the second resolution being higher than the first resolution.

Description

technical field [0001] The present disclosure relates to a fingerprint sensor-integrated touch screen panel, in particular, to a fingerprint sensor-integrated touch screen panel capable of sensing fingerprints. Background technique [0002] In recent years, computer-based systems (for example, tablet personal computers (PCs), smart phones, personal digital assistants (PDAs), automatic teller machines (ATMs) and Information system). Generally, computer-based systems store a variety of data, including confidential information such as business information and trade secrets as well as personal information related to personal matters. Therefore, enhancement of security for protecting confidential information is required. [0003] To this end, fingerprint sensors have been developed to enhance security by performing system enrollment or authentication using human fingerprints. [0004] A fingerprint sensor is a sensor capable of sensing a human's fingerprint. Fingerprint senso...
