Abstract: A display apparatus and an fingerprint sensing method thereof are provided. A display panel of the display apparatus has a pixel circuit array, an in-display touch sensor array, and an in-display fingerprint sensor array. A driving circuit drives the in-display fingerprint sensor array to read a fingerprint image. A current display frame period is divided into a plurality of unit periods, each of the unit periods includes at least one fingerprint sensing period and one or both of a display driving period and a touch sensing period. The driving circuit resets a current fingerprint sensor in the in-display fingerprint sensor array during a first fingerprint sensing period among these fingerprint sensing periods of the first display frame period. The driving circuit reads a sensing result of the current fingerprint sensor during a second fingerprint sensing period succeeding to the first fingerprint sensing period.

Abstract: A diagnostic device for measuring pulse waves from an upper arm is provided. The device includes a cuff, a sensor, and a processing circuit. The cuff provides continuously a pressure to arteries of the upper arm. Then the sensor measures a plurality of pulse waves from an upper arm in response to the pressure. The plurality of pulse waves includes a single pulse wave. The processing circuit, coupled to the sensor, generates data of the plurality of pulse waves. According to data of the single pulse wave extracted from the data of the plurality of pulse waves, the processing circuit computes and outputs diagnostic data.
