Provided display panel includes at least one pixel circuit and at least one light-emitting element. The at least one pixel circuit is configured to drive the at least one light-emitting element to emit light. The at least one pixel circuit includes a drive module and a light emission control module. The drive module is configured to generate a drive current. The light emission control module is configured to control the drive current to be transmitted to a light-emitting element in response to a light emission control signal. A display period of the display panel includes a first display stage and a second display stage, where in the first display stage, an ineffective pulse duration for the light emission control signal is T1, in the second display stage, an ineffective pulse duration for the light emission control signal is T2, and T1>T2.

Display panel and display device

Provided are a display panel and a display device. The display panel includes a light-emitting element and a pixel drive circuit electrically connected to the light-emitting element. The pixel drive circuit includes a drive transistor and a first reset module. The drive transistor is configured to control a drive current. The first reset module is connected to a first node and configured to provide a first reset voltage to the first node. The light-emitting element is connected to the first node. A working mode of the display panel comprise a first drive mode. A display frame in the first drive mode includes a valid frame and an invalid frame. In the first drive mode, a first reset voltage for the valid frame is different from a first reset voltage for the invalid frame.

Systems and techniques for communicating data as a function of frequency are presented. In an implementation, a system includes a microelectromechanical systems (MEMS) sensor, a digital signal processor and a frequency detection circuit. The digital signal processor is coupled to the MEMS sensor. The frequency detection circuit receives data encoded as a function of frequency from the digital signal processor via a clock communication channel.

Data communication based on frequency

A throat microphone may include one or more transducers that are in contact with the skin in the region of the larynx of person, and may provide a vibration signal to a processing unit. The vibration signal may also include energy and information relating to secondary physiological phenomena such as breathing and heartbeat, in addition to the desired sonic signal. The processing unit may utilize information relating to the secondary physiological phenomena to control a filter that outputs the desired sonic signal.
