Abstract: A display device is provided, and the display device includes a backlight module, a display module and a light directing component which are sequentially arranged. The backlight module is configured to periodically and sequentially emit collimated light in S different directions; the collimated light in different directions runs through the display module and arrives at the light directing component, in which S≥2; and the light directing component is configured to converge incident collimated light in a same direction to a same preset viewpoint and converge incident collimated light in different directions to different preset viewpoints, in which the preset viewpoints at least include two preset viewpoints belonging to a same eyeball. An image display method applied to the display device is also provided.

Abstract: A display panel and a display device are disclosed. The display panel includes an array substrate (21) and a driving IC (11). The array substrate (21) includes a shift register (211). The shift register (211) includes a plurality of shift register units (2111) which are connected in multi stages. The array substrate (21) further includes a charge pump (22) which is connected with each of the shift register units (2111). An input terminal of the charge pump (22) is connected with the driving IC (11). An output terminal of the charge pump (22) is connected with each of the shift register units (2111). According to the disclosure, a charge pump is disposed on the array substrate, so as to lower a cost of the display panel.
