The unit 20, through the energy balance of each other, thereby changing the surface tension characteristic of the interface, so that the interface property of the material layer 23 of the 12 1351531 is converted from the original water repellency to hydrophilicity, and at this time, the contact interface 2325 will adsorb the second fluid. 26 is adapted to change the surface tension characteristic, and the first fluid 25 is pressed toward the center such that the first fluid 25 and the second fluid 26 form a lens structure 2526 with each other and have an angle Θ, and the applied voltage and the curvature of the lens structure 2526. In direct proportion. When the two-dimensional image of the display device 2 displays the lens structure 2526 formed by the first fluid 25 and the second fluid 26, it can be converted into a three-dimensional image display. It should be noted that in the present embodiment, the material properties of the first fluid 25 and the second fluid 26 are selected, and the refractive index of the fluid is unequal in the refractive index of the fluid and the refractive index of the first fluid 25 must be greater than the second fluid 26 . Referring to FIG. 3A and FIG. 3B, another display device 2' according to the first preferred embodiment of the present invention is similar in structure to the first preferred embodiment, except that: The image conversion device 2a is rotated such that the second electrode substrate 22 faces the display panel 2b, and the output image display can be converted from a two-dimensional image to a three-dimensional image. Since the developing conversion device 2a and its imaging principle have been described in detail in the foregoing embodiments, they will not be described again. Referring to FIG. 4A, a display device 3 according to a second preferred embodiment of the present invention includes a display conversion device 3a, a display panel 3b, and a backlight module 3c. The image conversion device 3a of the present invention comprises a first electrode substrate 31, a second electrode substrate 32, and a plurality of display conversion units 30. The second electrode substrate 32 is disposed opposite to the first electrode substrate 31, and the image is displayed. The conversion unit 30 is disposed between the first electrode substrate 31 and the second electrode substrate 32. The display device 3 of the present embodiment is similar in composition to the display 13 1351531 device 2', except that the second material layer 34 of the display conversion unit 30 is replaced by the first material layer 33 and the addition of an insulating layer 31b3. The insulating layer 31b3 is adjacent to the horizontal electrode 31b1 of the first electrode layer, and the vertical electrode 31b2 extends to the first material layer 33 and is in contact with the insulating layer 31b3, so that the development converting unit 30 is only made of a water repellent material, for example, A material such as a chain aliphatic water repellent material, a telluride or Teflon is used as a plurality of contact interfaces 3335 with the first fluid 35 and the second fluid 36. In this embodiment, the image display of the display conversion device 3a of the display device 3 is activated as follows: when the voltages of the first electrode layer 31b and the second electrode layer 32b are in an off state or when a specific voltage is applied, At this time, the interface characteristics of the first material layer 33 and the second material layer 34 of the development converting unit 30 are water repellent, and a plurality of contacts are formed on the inner side of the groove structure 37 with the first fluid 35 and the second fluid 36. The interface 3335 is water repellent and therefore repels the underlying second fluid 36 to change its surface tension characteristics such that the first fluid 35 and the second fluid 36 form a lens structure 3536 having an angle θ with the contact interface 3335. Hey. When a voltage is applied or converted to the first electrode layer 31b and the second electrode layer 32b, electrostatic energy is increased in the image conversion unit 30, and energy balance is transmitted through each other, thereby changing the surface tension characteristic of the interface to cause the first material layer 33. The interface property will be converted from hydrophilic to hydrophilic. At this time, the contact interface 3335 will adsorb the second fluid 36 and change its surface tension characteristics, so that the first fluid 35 and the second fluid 36 are horizontal. display). It should be noted that the display device 3 of the present embodiment is opposite to the activation sequence of the image conversion of the display device 2 of the first preferred embodiment and the applied voltage is inversely proportional to the curvature of the lens structure 1351531 3536. In this embodiment, the material properties of the first fluid 35 and the second fluid 36 are selected to be unequal in the refractive index of the fluid and the refractive index h of the first fluid 35 must be smaller than the refractive index of the second fluid 36. N2. Referring to FIG. 4B, another display device 3' according to the second preferred embodiment of the present invention is similar in structure to the display device 3 of the second preferred embodiment, except that the image is to be imaged. The conversion device 3a is rotated such that the first electrode substrate 31 faces the display panel 3b, and the output image/display can be converted from a two-dimensional image to a three-dimensional image. The development conversion device 3a has been described in detail in the foregoing embodiments and will not be described again. In the imaging principle, the display device 3' of the present embodiment is the same as the display device 3 of the second preferred embodiment, and is opposite to the startup sequence of the image conversion of the display device 2 of the first preferred embodiment. The voltage is inversely proportional to the curvature of the lens structure 3536. To more specifically illustrate the two-dimensional and three-dimensional image display conversion process of the present invention, as shown in FIG. 5A to FIG. 5C, the display conversion device 2a of the first preferred embodiment and its two-dimensional image display are converted into The three-dimensional image display is exemplified, and the process of calculating the imaging data is described on the condition that the refractive index of the first fluid 25 is larger than the refractive index n2 of the second fluid 46. First, the imaging equation of geometric optics is: n / s + Ι / s ' = 1 / f η is the equivalent refractive index of the pixel to lens structure of the display panel, this embodiment is approximately equal to 1.5; s is the objective lens distance of about 2.54 Mm 15 1551531 S' is the distance between the viewer and the display unit 2 is about 1 m; f is the focal length; so it is known that f = 1.54 mm and its magnification m is: - m = d/p = ns'/s - d is the distance between the eyes of the viewer is about 65 mm p is the pitch of the alizarin is about 100 μπι Φ, so it is inferred that f = s' / (m + l) can be obtained after f = 1.54 mm. See Figure 5B The refractive index of the first fluid 25 is 1^ = 1.53; the refractive index of the second fluid 46 is ιι 2 = 1·33 ; , and f = 1.54 mm is known from the above formula, so that the radius of curvature R = = 0.30 mm can be known. This data can infer that the angle between the lens structure and the first material layer 23 is 0=49.51°. Referring to FIG. 5C, the angle between the lens structure and the first material layer 23 can be substituted into the following formula: ^1 cos0 = cos% + £〇 £ξΖ_ 2ίγ θ〇=90° θ=49.51° ε〇=8.85χ10'1,2 (F/m) εΓ=1.72 (Dielectric constant of the first material layer, dielectric of teflon 1351531 Constant) . t=1.0 μιη (first material layer thickness , eg Teflon thickness) g~0.03 N/m (the estimated surface tension of the first fluid/second fluid) • V~51V (applied voltage), the lens structure and the first material layer are determined by the applied voltage V The angle 23 of 23, that is, the curvature of the lens structure is determined by the applied voltage, and the voltage magnitude is proportional to the curvature of the lens structure, so it can be decided that when the display device φ 2 is converted from a two-dimensional image display to a three-dimensional image display, the viewer The position and viewing angle of the image can be determined. In summary, a display device and a display conversion device thereof according to the present invention utilize an increased electrostatic energy in the system to balance the energy between the first material layer and the second fluid.
