[0042] In this embodiment, the first fluid 331 is an aqueous fluid with conductive properties, the second fluid 332 is an oily fluid with insulating properties, and the surfaces of the first electrode layer 31 and the nano-grating layer 32 have hydrophobic properties. Wherein, the hydrophobic characteristic surface means that in a natural state (when no voltage is applied), the aqueous fluid condenses on the surface in the form of water droplets.
[0043] Figure 5 ~ Figure 7 It is a principle diagram for realizing grayscale display of the display panel according to the first embodiment of the present invention. Such as Figure 5 As shown, when no voltage is applied to the first electrode layer 31 and the second electrode layer 34, the aqueous fluid 333 has a large contact angle, condenses in the shape of water droplets and is located at the end side of the display area, and the nano-grating layer 32 is exposed to the oily fluid 334, When the refractive index of the oily flu...

[0050] In this embodiment, the structure of the display panel and the structure of the grating are the same as those of the first embodiment, and the materials of the first / second substrate, the first / second electrode layer, the first / second fluid, and the nano-grating layer are also the same as those of the first embodiment. Example is the same. Different from the first embodiment, the surfaces of the first electrode layer and the nano-grating layer in this embodiment have hydrophilic properties. Wherein, the hydrophilic characteristic surface means that in a natural state (when no voltage is applied), the aqueous fluid infiltrates on the surface and covers the entire surface.
[0051] The process of realizing grayscale display in this embodiment is: when no voltage is applied to the first electrode layer and the second electrode layer, the contact angle of the aqueous fluid on the hydrophilic surface is small, and the contact angle of the aqueous fluid on the first electrode...

[0053] In this embodiment, the structure of the display panel and the grating structure are the same as those in the first embodiment, and the materials of the first / second substrate, the first / second electrode layer and the nano-grating layer are also the same as those in the first embodiment. Different from the first embodiment, in this embodiment, the first fluid is an aqueous fluid with insulating properties, the second fluid is an oily fluid with conductive properties, and the surfaces of the first electrode layer and the nano-grating layer have oleophobic properties. Among them, removing the electrolyte in the aqueous fluid can be used to make the aqueous fluid have insulating properties, and adding conductive particles can be used to make the oily fluid have conductive properties.
[0054] The process of realizing the grayscale display in this embodiment is as follows: when the first electrode layer and the second electrode layer are not applied with voltage, the oily fl...
