Abstract: The present disclosure provides a display device and a display method. The display device includes: a memory for storing at least one pre-stored image; and a controller for: obtaining first and second target images according to the at least one pre-stored image; and controlling a display module, according to a first control instruction, to display the second target image and hide a display of at least one first sub-region in a first region in a frame displayed after switching from the first target image to the second target image. A size of the first target image is different from that of the second target image, and/or a position of the first target image in a display picture is different from that of the second target image. The first region represents a region within an outer contour of the first target image and not overlapping with the second target image.

Abstract: The invention discloses a plotting method for a three-dimensional time-space diagram showing a regional green-wave coordinated control effect. The plotting method includes the following steps: establishing a coordinate system of the three-dimensional time-space diagram; determining a specific position coordinate of each intersection in the coordinate system of the three-dimensional time-space diagram; generating a time prism of a signal timing plan of each intersection; determining a green-wave bandwidth of each arterial road; and generating a driving trajectory between the intersections, and making a green-wave band of each arterial road, and completing plotting.
