The display panel 300 is configured to display a screen, characters, numerals, and the like. The display panel 300 may be various in kind, and for example, it may be at least one of a liquid crystal display panel, an organic light emitting display panel, a digital tube, and the like.

Compared with a functional film layer in the prior art, the reflectivity can be improved, so that the imaging is clearer.
It can be understood that the functional film layer in the prior art has both light transmission and reflection capabilities, and in order to ensure the imaging and display effects, the transmittance and the reflectance of the functional film layer are relatively close, for example, both the transmittance and the reflectance are 50%.

Specifically, the light control layer 200 includes a first electrode layer 210, a functional layer 220, and a second electrode layer 230, and the first electrode layer 210 is a transparent electrode layer, and may be a transparent electrode layer made of conductive materials such as Indium Tin Oxide (ITO), Indium-Zinc Oxide (IZO), Zinc-gallium Oxide (GZO), Carbon Nanotube film (Carbon Nanotube-based films), metal nanowires, silicon (silicon), and Graphene (Graphene). The second electrode layer 230 is also a transparent electrode layer, and the material thereof may be the same as or different from that of the first electrode layer 210, and is not limited herein.
Preferably, the first electrode layer 210 and the second electrode layer 230 are indium tin oxide transparent conductive films, which are easy to process and low in cost.
The functional layer 220 is disposed between the first electrode layer 210 and the second electrode layer 230, a transparent electrolyte 221 may be encapsulated in the functional layer 220, the transparent electrolyte 221 may be a colorless solution so that light can pass through, the transparent electrolyte 221 may have metal ions, for example, the transparent electrolyte 221 may include zinc chloride, and the metal ions may be zinc ions. It is understood that the transparent electrolyte 221 may include various components, and the kind of the metal ions therein may be various.
The first electrode layer 210 and the second electrode layer 230 may be connected to two poles of the power module 400, so that a voltage is formed between the first electrode layer 210 and the second electrode layer 230, and metal ions may be reduced from the electrolyte solution by changing the voltage to form a simple metal substance, or the formed simple metal substance may be re-oxidized into metal ions. After the metal ions form the metal simple substance, the metal simple substance may be formed on the surface of the first electrode layer 210 or the second electrode layer 230 to form the metal layer 223.

Further preferably, the transparent electrolyte 221 may include tetrabutylammonium bromide, silver nitrate, and dimethyl sulfoxide, and the metal ion may be a silver ion.
When the mirror function of the mirror display device is required, when the first electrode layer 210 is connected to the positive electrode of the power module 400 (i.e., the voltage of the first electrode layer 210 is positive), and the second electrode layer 230 is connected to the negative electrode of the power module 400 (i.e., the voltage of the second electrode layer 230 is negative), the second electrode layer 230 is negatively charged, and since silver ions are positively charged, silver ions are collected on the upper surface of the second electrode layer 230 and reduced to form metallic silver. The metal silver forms the metal layer 223 on the second electrode layer 230, thereby implementing a function of reflecting light. At this time, the optical control layer 200 is in a reflective state. The metal layer 223 formed by silver has good reflection effect, can improve reflectivity and has good imaging effect.
On the contrary, when the display function of the mirror display device is required, by changing the voltage, for example, when the voltage of the first electrode layer 210 changes from a positive value to a negative value and the voltage of the second electrode layer 230 changes from a negative value to a positive value, the metal silver can be oxidized to form silver ions, and the silver ions enter the solution, and after the metal silver is completely oxidized, the metal silver can be cut off, so that the voltages of the first electrode layer 210 and the second electrode layer 230 are 0, and the optical control layer 200 is kept in a transparent state. It is understood that, in a certain voltage range, the metallic silver formed on the surface of the second electrode layer 230 may be oxidized into silver ions, and at the same time, the silver ions in the transparent electrolyte 221 may not form the metallic layer 223 on the surface of the first electrode layer 210.
