Abstract

The invention relates to the technical field of display. The invention discloses an ultrasonic display panel and a display device. The ultrasonic display panel comprises a substrate, the substrate isdivided into a plurality of sub-pixel units, the ultrasonic display panel further comprises an ultrasonic sensor, the ultrasonic sensor is located in each sub-pixel unit of the substrate, the ultrasonic sensor comprises a signal receiving end and a signal transmitting end, and the signal receiving end is electrically connected with a voltage supply circuit; the first insulating layer is positionedon one side, deviating from the substrate, of the ultrasonic sensor; the light-emitting circuit is arranged on the side, deviating from the ultrasonic sensor, of the first insulating layer and located in each sub-pixel unit, in each sub-pixel unit, the light-emitting circuit is electrically connected with the signal transmitting end of the ultrasonic sensor, and in the detection mode, an induction signal of the ultrasonic sensor controls the light-emitting circuit to display. According to the ultrasonic display panel, ultrasonic detection is simplified, the detection time during ultrasonic detection is effectively shortened, ultrasonic detection equipment is simplified, and the concept of intelligent home is realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an ultrasonic display panel and a display device. Background technique [0002] For ultrasonic testing, a special chip (called a transducer) generates mechanical vibrations under the excitation of electric pulses, and the vibrations generate ultrasonic pulses. During the propagation of ultrasonic pulses, they will be reflected or scattered back by the propagation medium. The echo reflected or scattered back to the transducer by the place with discontinuous physical properties is different, which can also cause the receiving transducer to vibrate, convert this vibration into an electrical signal, and perform different processing on the electrical signal, such as the propagation medium. The structure, surface topography and other information, the ultrasonic testing instruments currently used in hospitals are generally bulky and expensive, and the testing time and economic cost of ...

[0002] For ultrasonic testing, a special chip (called a transducer) generates mechanical vibrations under the excitation of electric pulses, and the vibrations generate ultrasonic pulses. During the propagation of ultrasonic pulses, they will be reflected or scattered back by the propagation medium. The echo reflected or scattered back to the transducer by the place with discontinuous physical properties is different, which can also cause the receiving transducer to vibrate, convert this vibration into an electrical signal, and perform different processing on the electrical signal, such as the propagation medium. At present, the ultrasonic testing instruments used in hospitals are generally bulky and expensive, and the testing time and economic cost of testing are relatively high in medical treatment, making it very inconvenient to use.
