Abstract

The invention discloses a display device and a method for controlling the same, and belongs to the field of display technologies. The display device comprises a display panel and a plurality of ultrasonic assemblies. The ultrasonic assemblies are arranged on the same layer; each ultrasonic assembly comprises a piezoelectric layer and two electrodes, and the two electrodes of each ultrasonic assembly are respectively arranged on two sides of the piezoelectric layer of the ultrasonic assembly. The display device is provided with the ultrasonic assemblies which are positioned on the same layer, ultrasonic waves can be transmitted and received by the ultrasonic assemblies without ultrasonic receiving assemblies or ultrasonic generating assemblies, accordingly, the problem of thick display panels in the prior art can be solved, and effects of reducing the thickness of the display panel can be realized.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display device and a control method of the display device. Background technique [0002] At present, various electronic devices have a fingerprint recognition function. More and more people are accustomed to using the fingerprint recognition function to perform various operations, such as unlocking the screen and confirming payment. [0003] A display device with a fingerprint recognition function includes a display panel, a plurality of ultrasonic wave receiving components arranged in the display panel, and a plurality of ultrasonic wave generating components arranged outside the display panel. When fingerprint recognition is performed, the ultrasonic generating component emits ultrasonic waves, which are reflected after touching the finger, and the ultrasonic receiving component receives the reflected ultrasonic waves. For the difference in ultrasonic absorpti...
