Communication is not easy to wait for. In order to respond to this trend and cooperate with the era of Internet popularization, the shortcomings of e-books can solve the shortcomings of traditional books. Therefore, when using the content to read related e-book content, you only need to borrow The information and content that you want to read can be obtained by accessing the physical memory device or the network.

The ink density is D, Δ / is a single layer; s thin ink thickness (7) 3 _ R is the graphite solid sphere radius 〇〇 nm), and e is the charge. The calculated e/m ratio of Formula 1 shows that the graphite is about 60 times as thin as that of the graphite particles. Therefore, the present example can maximize the charge-to-mass ratio of the two-dimensional sheet-like nanoparticle to be used, and The reaction rate to static electricity is fast, so that the color change can be quickly and power-saving in an electronic device such as an e-book or a flexible flat panel display, and the resolution is improved due to the particle size of the nanometer scale, and the image is clear and unambiguous. According to this principle, in the present embodiment, since the black graphite i 〇 7 is doped with a boron atom to make it positively charged, the white graphite i 〇 8 is doped with a carbon atom to be negatively charged. When the upper electrode 丨03a is negatively charged and the lower electrode 102a is positively charged, the black graphite 107 which is positively suspended in the oil droplet 1 〇5 is adsorbed to the upper electrode 1 〇3a terminal, and negatively charged. The white graphite suspended in the oil droplet 1 〇5 is adsorbed to the lower electrode 1 〇 2a end, so when After the line is injected into the oil droplet 1 〇5, the light can be reflected by the black graphite 1 〇7 in the oil droplet 105 adsorbed on the upper electrode 103a, and then emitted by the upper electrode 丨033 and the transparent plate 1〇4. The black light reflected by the person is obtained. 201211955 In addition to the black (black graphite) or white (white graphite) method, it can be formed by mixing oxides into the nano particles such as white graphite.

Therefore, when the upper electrode 10b is positively charged and the lower electrode is 1b2b When negatively charged, white graphite with negative charge suspended in oil droplet 1〇5 will be 8 is adsorbed on the end of the upper electrode 103b, and the black graphite 1〇7 which is positively suspended in the oil droplet 1〇5 is adsorbed on the end of the lower electrode 1〇21), so when the light is injected into the oil droplet 1〇5, The light is absorbed by the white graphite 1〇8 in the oil droplet 105 to the upper electrode end to generate a reflection %, and then the upper electrode 1031? and the transparent plate 104 are emitted to allow the user to obtain the reflected white light. The present embodiment is the same as that of the first embodiment. The difference is only that the upper electrodes 10a and 103b are respectively connected to the negative and positive charges, and the lower electrodes 1 〇2a and 1 〇2b are respectively connected to the positive and negative charges. The black graphite 10 7 and the white graphite 1 〇 8 in the oil drop 1 〇 5 are displayed as shown in Fig. 3, thereby showing the color bounded between black and white. 201211955 Therefore, the present invention provides an electronic device such as an e-book or a flexible flat panel display, which can make the image display speed fast and clear, and increase its legibility and wide application.
