Abstract: Methods, devices and systems for controlling an ultrasonic fingerprint sensor are disclosed. Some examples involve determining that a first bias voltage is not sufficient for one or more affected ultrasonic receiver pixels of the ultrasonic receiver array and determining one or more affected regions of the ultrasonic receiver array in which the one or more affected ultrasonic receiver pixels are located. Some examples involve determining one or more unaffected regions of the ultrasonic receiver array in which the one or more affected ultrasonic receiver pixels are not located. Some examples involve determining a second bias voltage for the one or more affected regions and recalibrating the ultrasonic fingerprint sensor to apply the second bias voltage to the affected regions and to apply the first bias voltage to the one or more unaffected regions when the ultrasonic receiver array receives ultrasound signals.

Abstract: A button module with vibration feedback and fingerprint sensing, a fingerprint sensing module for the same, and a control method for the same are provided. The fingerprint sensing module has a fingerprint sensing unit stacked on a vibration unit. When the fingerprint sensing module detects a fingerprint, the control unit or a host of an electronic device determines whether the fingerprint is authenticated. If it is not authenticated, the vibration unit is activated, so that the user realizes that the authentication is not passed in real time through the vibration. Then the user may quickly change another finger or move the finger's position to speed up the authentication process. This can prevent users from waiting to improve user experience.

Abstract: A display may have an array of organic light-emitting diode display pixels operating at a low refresh rate. Each display pixel may have six thin-film transistors and one capacitor. One of the six transistors may serve as the drive transistor and may be compensated using the remaining five transistors and the capacitor.

Two different emission signals controlling each pixel may be toggled together using a pulse width modulation scheme to help provide darker black levels.

Abstract: This invention is related to a technical field of optical fingerprint recognition. It particularly designs a coordinate transformation method for imaging under screen, a storage medium and an electronic device. The a [sic] coordinate transformation method for imaging under screen includes steps of: calculating a coordinate system shrink coefficient; copying each luminous point in a fingerprint image to a shrunken coordinate system; and moving the entirety to the shrunken coordinate system with a relative distance between fingerprint information around a luminous point and a center of the luminous point being kept unchanged. Through coordinate transformation, restoration of the fingerprint image is guaranteed, and also pixels are guaranteed to not be lost at the same time, thereby ensuring the definition of the fingerprint image thus restored. In addition, this manner for restoring fingerprint images is simple in calculation process, fast in restoration speed, and good in quality.
