Abstract: A display device with a fingerprint sensing function is provided. The display device includes a display panel and a sensor panel. The display panel includes a plurality of display pixels. The sensor panel is disposed under the display panel. The sensor panel includes a plurality of sensor pixels arranged in an array. The array has a first sensor pitch in a first direction. Each of the sensor pixels includes a sensor. Every two neighboring sensors of the sensors have a first shift pitch in the first direction, and the first shift pitch is not equal to the first sensor pitch.

Abstract: A random number generator includes a pre-processing circuit and a chaos random number generator (CRNG). The pre-processing circuit includes a perturbation source and a control circuit, wherein the control circuit is coupled to the perturbation source. The CRNG, which is coupled to the pre-processing circuit, includes a chaos system and a post-processing circuit, wherein the post-processing circuit is coupled to the chaos system.
