Problems solved by technology

[0002] With the prevalence of digital devices, the security of digital information has gradually been paid attention to. Traditionally, users are required to enter a password. In addition to the possibility that the user password may be stolen by others, in order to further improve security, the user will enter the password every predetermined period. You are required to reset a set of passwords, so you may forget your password and be unable to log in to the system

Embodiment Construction

[0018] Please refer to figure 1 As shown, it is a block diagram of a touch display device 10 according to an embodiment of the invention. The touch display device 10 includes a display 11 and a touch device 13; wherein, the touch device 13 may be, for example, a capacitive touch device or a resistive touch device (in this description, a capacitive touch device is used as an example for description. ), combined with one side of the display surface of the display 11. In other words, the user views the display image of the display 11 through the touch device 13, so the touch device 13 is preferably made of a transparent material, such as a glass substrate or a transparent plastic substrate formed with transparent electrodes (such as oxide Indium tin). The display 11 may be, for example, a liquid crystal display, a plasma display, an organic light-emitting diode display, etc., and there is no specific limitation; a liquid crystal display is taken as an example in this description....

Abstract

The invention discloses a touch display apparatus. The touch display apparatus comprises a display and a touch apparatus. The display comprises a glass substrate. The touch apparatus is combined with the glass substrate and comprises a touch region, a fingerprint detection region and a control circuit. The touch region comprises a first detection unit matrix arranged by a first grid distance. The fingerprint detection region comprises a second detection unit matrix arranged by a second grid distance. The control circuit is used for controlling detection operations of the touch region and the fingerprint detection region, and adjusting an effective grid distance of the fingerprint detection region according to a first touch position.

Description

Technical field [0001] The present invention relates to a touch display device, and more particularly to a touch display device with touch and fingerprint recognition functions and an operating method thereof. Background technique [0002] With the prevalence of digital devices, the security of digital information is gradually being valued. The traditional way of requiring users to enter a password, except that the user’s password may be stolen by others, in order to further improve security, users will You are asked to reset a set of passwords, so you may not be able to log in to the system if you forget your password. [0003] In recent years, physiological characteristics have gradually replaced user passwords as a way to protect digital information. Among them, fingerprints can be used as an authentication method for logging in to the system because of their uniqueness and easy operation. However, the separate fingerprint identification device is inconvenient to use, so it is ...
