Claim 18:
19. The displaying driving method according to claim 14, wherein:
the displaying device further comprises a subarea peep-proof displaying mode, and in the subarea peep-proof displaying mode, corresponding pixels in the LCD panel are controlled to be in the light transmission state according to the front displaying information, the second electric field is controlled to be formed between the transparent electrode shields and the electrode plates of each of the corresponding electron microscope assemblies in a peep-proof area, and the first electric field is controlled to be formed between the transparent electrode shields and the electrode plates of each of the corresponding electron microscope assemblies in a non-peep-proof area;
the displaying device further comprises a back displaying mode, and in the back displaying mode, each pixel in the LCD panel is controlled to be in a non-transparent state, the transparent electrode shield and the electrode plate in the electron microscope assembly at a corresponding position are controlled to be in an unpowered state according to back displaying information, and the transparent electrode shields and the electrode plates in the plurality of electron microscope assemblies at remaining positions are controlled to be in a corresponding powered state to form the first electric fields or the second electric fields; and
the displaying device further comprises a back mirror surface mode, and in the back mirror surface mode, each pixel in the LCD panel is controlled to be in the non-transparent state, and the first electric field is at least controlled to be formed between the transparent electrode shields and the electrode plates of each of the plurality of electron microscope assemblies in a central area.
