Samsung OLED flexible display device is delayed due to quality problems

Samsung's first flexible display device has been postponed due to problems with display quality.
South Korean newspaper ETnews reported that Samsung is expected to launch its first device with a flexible display at the end of this year. Since the OLED panel is not resistant to oxygen and moisture, the packaging step is critical to the commercial production of flexible displays. Samsung Display is said to be evaluating a variety of packaging technologies to replace the packaging technology developed by Vitex System. This is undoubtedly bad news for Samsung.
Samsung's old rival LG recently publicly stated that they will launch a flexible screen smartphone before Samsung this year. LG has previously received funding from the Korean government for the development of this new display technology.

Yuhai Company is engaged to research and development of piezoelectric products and related piezoelectric products,  the related piezoelectric products includes the piezo sensors and transducer. 

The Ultrasonic Transducer is a kind of transducer that converts the ultrasonic signal into electric signal, or vice versa. Ultrasound transmitter and receiver is a transducer that can transmit and receive ultrasound. Ultrasound sensor is a kind of sensor, in essence, it is also a transmitter and receiver. The working principle of this kind of equipment is similar to that of radar and sonar. Active ultrasonic sensors can emit and receive reflected waves, and determine the distance of the target by measuring the time interval between transmission and reception. Passive Ultrasonic Sensor is actually a microphone that can convert ultrasonic signal into electrical signal.

According to the working principle and materials used, the ultrasonic transducer has Piezoelectric Transducer, electrostatic transducer (capacitive transducer), magnetostrictive transducer, electromagnetic acoustic transducer, mechanical transducer and other types [1].
