Display device and display method thereof

A display device, comprising a display panel and a microlens array disposed on a light-emitting side of the display panel, wherein the display panel comprises a plurality of pixel islands, and the microlens array comprises a plurality of microlens units in one-to-one correspondence with the plurality of pixel islands;

• wherein an orthographic projection of each of the microlens units on the display panel is coincident with or disposed within a region where a corresponding pixel island is disposed;
• and
• each of the pixel islands comprises a plurality of sub-pixels arranged in an array, wherein the sub-pixels in a same pixel island display a same color, and the plurality of pixel islands comprise a first pixel island displaying a first color, a second pixel island displaying a second color, and a third pixel island displaying a third color, the first pixel island, the second pixel island, and the third pixel island adjacent to one another forming a repeating unit;
• wherein in a same repeating unit, a first sub-pixel in the first pixel island, a second sub-pixel in the second pixel island, and a third sub-pixel in the third pixel island are disposed at three vertexes of a triangle respectively, wherein the first sub-pixel, the second sub-pixel, and the third sub-pixels are disposed at same positions respectively relative to the microlens unit corresponding to the first pixel island, the microlens unit corresponding to the second pixel island, and the microlens unit corresponding to the third pixel island.
