The first electrode 231, the second electrode 232, and the third electrode 233 may be transparent electrode sheets, such as ITO (Indium tin oxide) electrodes, graphene electrodes, and the like, so that the installation of the first electrode 231, the second electrode 232, and the third electrode 233 between the first glass substrate 21 and the second glass substrate 22 will not affect the light transmission. The first electrode 231 is fixed on the first glass substrate 21 and the second electrode 232 is disposed opposite the first electrode 231 such that the first electrode 231 and the second electrode 232 constitute a set of parallel plate capacitors. Specifically, the first electrode 231 and the second electrode 232 are spaced apart from each other by an insulating layer 25, the first electrode 231 is fixed on the first glass substrate 21, the second electrode 232 and the first electrode 231 are connected to each other by the insulating layer 25, the insulating layer 25 may be made of a transparent insulating material such as organic glass or epoxy resin, so that the first electrode 231 and the second electrode 232 are spaced apart from each other, and when the first electrode 231 and the second electrode 232 are energized, an electric field generated by a parallel plate capacitor formed by the first electrode 231 and the second electrode 232 is diffused in both sides. The third electrode 233 is fixed on the second glass substrate 22 with a space between the second electrode and the third electrode to form a parallel plate capacitor, and an electric field from the positive plate to the negative plate is formed between the second electrode 232 and the third electrode 233.

The charged particles 2341 are conductive particles that can reflect light. The transmission body 234 may be a transparent sphere or a transparent body with other shapes. The transmissive body 234 has a cavity therein and the charged particulate matter 2341 is disposed in the cavity inside the transmissive body 234. The polarity of the first electrode 231 is opposite to that of the second electrode 232, and the polarity of the first electrode 231 is the same as that of the third electrode 233.
In the embodiment of the present application, when the charged particles 2341 have different charging properties, the polarities of the first electrode 231, the second electrode 232, and the third electrode 233 are also different.
In one possible implementation, the charged particulate matter 2341 is positively charged particulate matter, the first electrode 231 and the third electrode 233 are negative electrode plates, and the second electrode 232 is a positive electrode plate.
Specifically, in the case where the first electrode 231 and the third electrode 233 are negative electrode plates and the second electrode 232 is a positive electrode plate, the electric field outside the parallel plate capacitor formed by the first electrode 231 and the second electrode 232 is a divergent electric field that the second electrode 232 spreads toward the first electrode 231, and the electric field inside the parallel plate capacitor formed by the second electrode 232 and the third electrode 233 is a vertical electric field that the second electrode 232 points toward the third electrode 233. In this way, when the charged particles 2341 are positively charged particles and the display device needs to perform mirror display, the second electrode 232 and the third electrode 233 can be controlled to be powered on, so that the positively charged particles are converged to the top of the transmissive body 234 under the action of the vertical electric field between the second electrode 232 and the third electrode 233, and external light is reflected when being irradiated on the positively charged particles, thereby forming a mirror display effect at the reflection module 2.

In another possible implementation, the charged particles 2341 are negatively charged particles, the first electrode 231 and the third electrode 233 are positive plates, and the second electrode 232 is a negative plate.
Specifically, in the case where the first electrode 231 and the third electrode 233 are positive plates and the second electrode 232 is a negative plate, the electric field outside the parallel plate capacitor formed by the first electrode 231 and the second electrode 232 is a divergent electric field that the first electrode 231 spreads toward the second electrode 232, and the electric field inside the parallel plate capacitor formed by the second electrode 232 and the third electrode 233 is a vertical electric field that the third electrode 233 directs toward the second electrode 232. Thus, when the charged particles 2341 are positively charged particles, and the display device needs to perform mirror display, the second electrode 232 and the third electrode 233 can be controlled to be powered on, so that the negatively charged particles are converged to the top of the transmissive body 234 under the action of the vertical electric field between the second electrode 232 and the third electrode 233, and external light is reflected when being irradiated on the negatively charged particles, thereby forming a mirror display effect at the reflection module 2. When the display device displays content, the first electrode 231 and the second electrode 232 can be controlled to be electrified, so that the positively charged particles are gathered to the side of the transmitter 234 under the action of the diffusion electric field between the first electrode 231 and the second electrode 232, and light of the display module 1 can be irradiated to the outside through the transmitter 234 to form a display picture. The negatively charged particles may be negatively charged particles with a certain luminescence property, such as non-metal or non-metal oxide, and the embodiment of the present invention is not limited thereto.
