Problems solved by technology

[0004] Embodiments of the present invention provide a display panel and a display device, which can solve the problem in the prior art that since the acoustic wave touch module is arranged in the surrounding frame area of ​​the panel main body, the direction of sound wave propagation is along the horizontal direction of the surface of the panel main body. As the size of the display panel increases, the propagation path of the sound wave also increases, which makes it difficult for the function of the sound wave touch module to meet the technical problems

Abstract

The invention discloses a display panel and a display device. The display panel comprises a panel body and a sound wave touch module. The panel body comprises a light emitting side and a back side which are opposite to each other, the sound wave touch module is arranged on the back side of the panel body and comprises a generator and a sensor, and the generator is used for emitting first sound waves in the direction from the back side of the panel body to the light emitting side; the sensor is used for receiving a second sound wave reflected from the light emitting side of the panel main body to the back side; the sound wave emitted by the sound wave touch module is spread in the thickness direction of the panel main body, so that the spreading of the sound wave is not influenced by the plane size of the display panel, and the sound wave touch module is suitable for large-size display.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device with the display panel. Background technique [0002] Ultrasonic fingerprint recognition technology will not be disturbed by water and oil, and has stronger environmental adaptability, so ultrasonic fingerprint recognition technology is widely used. For example, ultrasonic fingerprint recognition technology is used in various fields to improve the security of electronic products such as mobile phones, computers, tablets and access control systems. Compared with traditional digital passwords, due to the rapidity of fingerprint unlocking, ultrasonic fingerprint recognition technology brings a lot of convenience to people's lives. [0003] Please refer to Figure 1A as well as Figure 1B , is an existing surface acoustic wave touch display panel, wherein the display panel includes a panel body 1, and a reflector 2 and a transmitting tr...
