Abstract

The invention provides a display device and a terminal, the display device comprises at least one display unit, a light-emitting layer in the display unit is arranged on a first side of a substrate and comprises a sub-pixel area and a non-sub-pixel area, the light-emitting layer in the sub-pixel area is used for emitting incident light in all directions, a semi-reflecting and semi-transmitting film is arranged on a propagation path of the incident light, and the semi-reflecting and semi-transmitting film is arranged on a second side of the substrate. The first reflecting surface of the semi-reflecting and semi-transmitting film is parallel to the light emitting surface of the light emitting layer or forms an included angle larger than 0 degree and smaller than 45 degrees with the light emitting surface of the light emitting layer, the semi-reflecting and semi-transmitting film is used for reflecting at least part of incident light in multiple first directions to obtain first reflecting light, and the first retroreflective film is arranged on the propagation path of the first reflecting light and located on the first side of the substrate; and the semi-reflecting and semi-transmitting film is arranged corresponding to the non-sub-pixel area, is used for reflecting the first reflection light along each second direction which is opposite to the first reflection light to obtain second reflection light, and is also used for transmitting at least part of the second reflection light along each second direction so as to be converged on the observation surface. The display device is small in size and high in brightness efficiency.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to a display device and a terminal. Background technique [0002] The floating display technology can directly display the picture in the air without the need for a display screen. It has become a popular research direction in the environment of reducing unnecessary contact. [0003] like figure 1 As shown, it is a schematic structural diagram of the current floating display device. The floating display device includes a substrate 21, a light-emitting layer 22, a transflective film 23 and a retro-reflective film 24, wherein the substrate 21 and the light-emitting layer 22 are arranged horizontally, and the retro-reflective film 24 is vertical. Arranged at one end of the light-emitting layer 22, the transflective film 23 forms an included angle of 45 with the light-emitting layer 22 and the retroreflective film 24. When the light 100 emitted by the light-emitting lay...
