Abstract: A texture image acquiring device, a display device and a collimator are disclosed. The texture image acquiring device includes a collimator and an image sensor. The collimator includes a lens array, a first diaphragm layer, and a second diaphragm layer. The lens array allows light rays to be converged and incident on the first diaphragm layer. The first diaphragm layer allows light rays incident on the first diaphragm layer to pass through and be incident on the second diaphragm layer, and restricts an angle of light rays capable of passing through the first diaphragm layer. The second diaphragm layer allows light rays incident on the second diaphragm layer to pass through, and restricts an angle of light rays capable of passing through the second diaphragm layer. The image sensor senses light rays incident on the image sensor for acquiring a texture image.

Abstract: The present disclosure provides a fingerprint sensing sub-circuit, a fingerprint sensing circuit, a fingerprint recognition method, a sensor, a touch display panel and a display device. The fingerprint sensing sub-circuit includes an acoustic wave generation circuit and an acoustic wave reception circuit. The acoustic wave generation circuit is configured to generate an ultrasonic wave. The acoustic wave reception circuit is configured to collect a voltage signal, convert the voltage signal into a current signal, and output the current signal to a signal output end. The acoustic wave generation circuit and the acoustic wave reception circuit are separated from each other, so that the fingerprint sensing sub-circuit operates in a mode where a transmitting operation and a receiving operation are separated from each other.
