Abstract: Provided is a three-dimensional (3D) display device and display method. The 3D display device includes a zoom lens unit; and a two-dimensional display unit, which is located on a side of the zoom lens unit, where a distance between the two-dimensional display unit and the zoom lens unit is less than a minimum focal length of the zoom lens unit; where the two-dimensional display unit is used for displaying multiple two-dimensional images of a three-dimensional picture, and the multiple two-dimensional images corresponds different depth of field. When the two-dimensional display unit displays the two-dimensional images corresponding to different depth of field, the zoom lens unit has a different focal length for the depth of field corresponding to each of the plurality of two-dimensional images. The display time of the three-dimensional picture is less than visual persistence time.

Abstract: The present disclosure provides a light-emitting unit and a display device. The light-emitting includes a micro-LED element and a bonding pad. The micro-LED element includes an element pin, the bonding pad includes a bonding pin, in each welding pair of the element pin and the bonding pin, a length of the element pin is greater than a width of the bonding pin, and a non-zero angle is formed between the extending direction of the element pin and the extending direction of the bonding pin. When the element pin is deviated from the bonding pin in a certain range, the element pin can still be aligned accurately with the bonding pin. Thus, a requirement on the alignment precision between the micro-LED element and the bonding pad is lowered in a certain extent, thereby improving the yield.
