The invention relates to a touch screen, a method and a device for realizing fingerprint identification and touch control. By detecting a touch operation on the touch screen, the area corresponding to the touch operation is provided with a touch electrode and a fingerprint identification electrode; through the touch electrode and the fingerprint identification electrode Obtain the first capacitance value corresponding to the touch operation; obtain the second capacitance value corresponding to the touch operation through the fingerprint identification electrode; thereby judge whether to respond to the touch request corresponding to the touch operation according to the first capacitance value and the second capacitance value, thereby passing the touch Operate the touch electrodes and fingerprint identification electrodes set in the corresponding areas to realize fingerprint identification and touch functions, avoiding the use of optical and radio frequency fingerprint unlocking components, thereby reducing the thickness of the terminal.
Description
technical field [0001] The present invention relates to the field of display technology, and in particular, to a touch screen, a method and a device for realizing fingerprint recognition and touch control. Background technique [0002] With the development of touch technology and display technology, touch display devices have been sought after by more and more people. Taking common touch-type smart mobile terminals as an example, its increasingly high screen ratio is designed for users It brings a more extreme visual experience than before. However, while the screen ratio of smart mobile terminals has increased, the space left for users to identify fingerprints for security authentication is getting smaller and smaller. [0003] In order to allow the terminal to achieve a higher screen ratio, some terminal manufacturers set the fingerprint unlocking on the back of the fuselage. The fingerprint unlocking will affect the aesthetics of the back cover of the terminal. In order t...
