At present, transparent display panels are increasingly popular among display products due to the advantages of high permeability, simple structure, light weight, quick installation, convenient maintenance, greenness, energy conservation, good heat dissipation performance and the like. With the development of display technology, people generally need a double-sided display device capable of displaying images on both sides of a transparent display panel. The double-sided display device is applied to business halls in the communication industry, advertising boards, government windows, financial industry, traffic industry and window industry, such as various public places with large pedestrian volume, such as airports, railway stations, subway stations, dining halls and the like, and therefore, the double-sided display device has wide application prospect.
However, in the conventional transparent display panel, the light source is disposed on one side of the substrate, so that the display panel can only perform single-sided display, and cannot perform double-sided display.

Specifically, the display unit 110 provided by the present invention can be manufactured and sold separately. A plurality of display units 110 may be assembled into the display panel 100 and then sold.
As shown in fig. 1 and 2, the display unit 110 includes: display substrate 111, a plurality of light emitting units, first prism 113, and second prism 114.
A plurality of light emitting units are disposed on the display substrate 111, and the display substrate 111 is preferably a transparent substrate; specifically, the display substrate 111 may be a transparent inorganic substrate, such as quartz or glass, or a transparent plastic, or a transparent substrate made of other common transparent materials.
The light emitting units may be Micro light emitting diode chips (Micro-LEDs), and preferably, the light emitting units are arranged on the display substrate 111 in an array, and the distance between adjacent light emitting units may be determined by those skilled in the art according to the power of the light emitting units, which is not limited herein.
The first prism 113 and the second prism 114 are transparent objects surrounded by planes which intersect each other two by two but are not parallel to each other, for splitting or dispersing light beams. Specifically, the first prism 113 and the second prism 114 may be made of optical glass or crystal with high light transmittance to improve the transparency of the display unit 110 thereof.
The first prism 113 and the second prism 114 are disposed on the light emitting side (the side where the light emitting unit is disposed) of the display substrate 111, and in the present embodiment, each of the first prism 113 and the second prism 114 has at least three planes, where the first prism 113 has a first light emitting surface 20, a first inclined surface 30, and a first side surface 40; the second prism 114 has a second light emitting surface 50, a second inclined surface 60 and a second side surface 70, when assembled, the first inclined surface 30 of the first prism 113 and the second inclined surface 60 of the second prism 114 are closely attached together, the first light emitting surface 20 and the second light emitting surface 50 are respectively located at the upper side and the lower side of the display unit 110 in the thickness direction 10, and the first side surface 40 and the second side surface 70 are respectively located at the left side and the right side of the display unit 110.
A display substrate 111 is provided on the first side surface 40 side of the first prism 113 (right side of the first side surface 40 in fig. 1), and after a part of light rays (denoted as first light rays 1) of the light emitting unit on the display substrate 111 enter the first prism 113 from the first side surface 40, after being reflected by the first inclined surface 30, the light is emitted from the first light emitting surface 20, and another part of the light (labeled as the second light 2) enters the first prism 113 from the first side surface 40, and then enters the second prism 114, reflected by the second side surface 70 and then reflected by the second inclined surface 60 to the second light emitting surface 50 for emitting, thereby allowing both sides of the display unit 110 to be displayed, realizing a double-sided display of the display unit 110, and, at the same time, the third light ray 3 can directly pass through the prism due to the optical transparency of the first prism 113 and the second prism 114 in the display unit 110, and thus, the display unit 110 is a transparent display unit 110.
It should be noted that, the conventional transparent screen light source is disposed on one side of the substrate, the substrate is disposed parallel to the display surface, and the smaller the light source distance, the lower the transmittance thereof, so that in order to ensure the transparency thereof, the distance between the conventional transparent screen light source needs to be set larger, which affects the definition thereof, in this embodiment, since the display substrate 111 is disposed vertically, the distance between the adjacent light emitting units does not affect the transmittance of the display unit 110, and the distance between the adjacent light emitting units can be properly reduced, so as to improve the display definition of the first light emitting surface 20 and the second light emitting surface 50.
