Description of the Invention: [Technical Field of the Invention] The present invention relates to an electrowetting display (Electro-wetting display). [Prior Art] An electrowetting display is a newly developed display in recent years, which has characteristics of low power consumption, wide viewing angle, and high response speed. Therefore, electrowetting displays are well suited for use in portable electronic products. Referring to Figure 1, there is shown a cross-sectional view of a prior art electrowetting display in a dark state. The electrowetting display 10 includes a display panel 11 and a backlight module 12 disposed opposite the display panel 11. The backlight module 12 provides a uniform planar backlight to the display panel 11. The display panel 11 includes a first substrate 13 , a second substrate 14 , and a first fluid 15 , a second fluid 16 , a plurality of electrodes 17 , and a repulsion between the first substrate 13 and the second substrate 14 . The aqueous insulating layer 18 and the plurality of insulating walls 19. The plurality of electrodes 17 are made of a transparent conductive material such as Indium Tin Oxide (IT0) or Indium Zinc Oxide (IZO). The plurality of electrodes 17 are arranged in a matrix on the surface of the second substrate 14. Each of the electrodes 17 defines a pixel region P, and the adjacent two pixel regions form a gap 171. The water-repellent insulating layer 18 is made of a transparent material. The aqueous insulating layer 18 covers the plurality of electrodes 17 and the gap 171. The plurality of insulating walls 19 are made of a transparent material, and a gap 21 171 corresponding to the electrodes 17 is provided on the surface of the water-repellent insulating layer 18. The second fluid 16 is filled between adjacent insulating walls 19. The material of the second fluid 16 is typically an opaque color oil or a cetane-like alkane. The first fluid 15 is filled between the second fluid 16 and the first substrate 13, and is a transparent conductive liquid that is incompatible with the second fluid 16, such as water, a salt solution, and dissolved potassium chloride. (KC1) A mixed solution of water and ethanol. When the first fluid 15 and the electrode 17 are not applied with a voltage, the electrowetting display 10 is in a dark state. At this time, the first fluid 15 and the second fluid 16 are stacked, and the second fluid 16 shields the electrode 17 corresponding thereto. The light emitted from the backlight module 12 and the corresponding portion of the electrode 17 is sequentially absorbed by the second fluid 16 through the second substrate 14, the electrode 17, and the water repellent insulating layer 18. The light emitted by the backlight module 12 and the corresponding portion of the insulating wall 19 passes through the second substrate 14, the water repellent insulating layer 18, the insulating wall 19, the first fluid 15 and the first substrate 13 to pass through the light. The display panel 11 is displayed. Referring to Figure 2, there is shown a cross-sectional view of the electrowetting display 10 shown in Figure 1 in a bright state. A voltage is applied to the first fluid 15 and the electrode 17 to move the second fluid 16 toward the adjacent insulating wall 19 such that the first fluid 15 contacts a portion of the surface of the water repellent insulating layer 18. At this time, the light emitted by the backlight module 12 passes through the display panel 11. The isolation wall 19 of the electrowetting display 10 is made of a transparent material. When the electrowetting display 10 is in a dark state, the backlight module 12 and the corresponding portion of the isolation wall 19 emit light through the isolation. The wall 19 passes through the display panel 11, causing the brightness of the electrowetting display 10 to increase in a dark state, thereby reducing the contrast of the electrowetting display 10 to display the face. 200921146. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide an electrowetting display with improved contrast. An electrowetting display comprising a substrate, a fluid disposed on the substrate, and at least one insulating wall disposed on the substrate. Each barrier wall contains a material that absorbs light. An electrowetting display comprising a substrate, a fluid disposed on the substrate, and at least one insulating wall disposed on the substrate. The barrier wall absorbs light that strikes the barrier wall. Compared with the prior art, the insulating wall of the electrowetting display of the present invention absorbs the light that is irradiated to the insulating wall, and therefore, when the electrowetting display displays a dark state, the light irradiated to the insulating wall is absorbed, thereby reducing the The brightness of the electrowetting display in the dark state increases the contrast of the electrowetting display. [Embodiment] Referring to Fig. 3, a cross-sectional view of an electrowetting display according to a first embodiment of the present invention in a dark state is shown. The electrowetting display 20 includes a display panel 21 and a backlight module 22 disposed opposite the display panel 21. The backlight module 22 provides a uniform planar backlight to the display panel 21. The display panel 21 includes a first substrate 23, a second substrate 24, and a first fluid 25, a second fluid 26, and a plurality of electrodes 27 between the first substrate 23 and the second substrate 24. The aqueous insulating layer 28 and the plurality of insulating walls 29. The plurality of electrodes 27 are made of a transparent conductive material such as indium tin oxide or oxygen 200921146. Indium zinc. The plurality of electrodes 27 are arranged in a matrix on the surface of the second substrate 24. Each of the electrodes 27 defines a pixel region P, and the adjacent two pixel regions form a gap 271. The water repellent insulating layer 28 is made of a transparent material such as a water repellent transparent amorphous fluoropolymer, which is AF1600 in the present embodiment. The water repellent insulating layer 28 covers the plurality of electrodes 27 and the gap 271. Please refer to FIG. 3 and FIG. 4 together. FIG. 4 is a perspective view of some components of the electrowetting display 20 shown in FIG. The insulating wall 29 corresponds to the gap 271 between the electrodes 27, and is disposed in a lattice shape on the surface of the water repellent insulating layer 28. The spacer wall 29 is formed in a lattice shape to form a plurality of receiving spaces (not shown) corresponding to the pixel regions defined by the plurality of electrodes 27, respectively. The insulating wall 29 includes a first insulating wall 291 and a second insulating wall 292 which are sequentially stacked. The first insulating wall 291 is disposed adjacent to the water repellent insulating layer 28. The first insulating wall 291 is made of a material having a lower light transmittance, for example, a tree doped with carbon black or chromium (Chromium, Cr), an ester. Therefore, the first insulating wall 291 forms a light absorbing layer. The second insulating wall 292 is a light transmitting layer. Referring to FIG. 3 again, the second fluid 26 is filled in the receiving space formed by the adjacent insulating wall 29. The material of the second fluid 26 is usually an opaque color oil or a cetane-like alkane, which is a black ink in the present embodiment. The first fluid 25 is filled between the second fluid 26 and the first substrate 23, and is a transparent conductive liquid that is incompatible with the second fluid 26, such as water, a salt solution, and dissolved potassium chloride. (KC1) a mixed solution of water and ethanol. When the first fluid 25 and the electrode 27 are not applied with a voltage, the electrowetting is 9200921146. The display 20 is in a dark state. At this time, the first fluid 25 and the second fluid 26 are stacked, and the second fluid 26 shields the electrode 27 corresponding thereto. The light emitted by the backlight module 22 and the corresponding portion of the electrode 27 is sequentially blocked or absorbed by the second fluid 26 through the second substrate 24, the electrode 27 and the water repellent insulating layer 28. A part of the light is blocked or absorbed by the first insulating wall 291 after passing through the second substrate 24 and the water repellent insulating layer 28. Referring to FIG. 5, a cross-sectional view of the electrowetting display 20 shown in FIG. 3 is shown in a bright state. The first fluid 25 and the electrode 27 apply a voltage to move the second fluid 26 toward the adjacent insulating wall 29 such that the first fluid 25 is in surface contact with a portion of the surface of the water repellent insulating layer 28. At this time, the light emitted from the backlight module 22 and the corresponding portion of the insulating wall 29 is sequentially absorbed by the first insulating wall 291 through the second substrate 24 and the water repellent insulating layer 28. The light emitted from the backlight module 22 and the portion corresponding to the second fluid 26 passes through the second substrate 24, the electrode 27, and the water repellent insulating layer 28, and is absorbed by the second fluid 26. The light emitted from the remaining portion of the backlight module 22 passes through the second substrate, the plate 24, the electrode 27, the water repellent insulating layer 28, the first fluid 25, and the first substrate 23 to pass through the display panel 21. The insulating wall 29 of the electrowetting display 20 of the present invention includes a first insulating wall 291 having the property of absorbing or blocking light as compared to the prior art. When the electrowetting display 20 is in a dark state, the light emitted by the backlight module 22 and the corresponding portion of the insulating wall 29 is absorbed by the first insulating wall 29 1 when passing through the insulating wall 29. Therefore, when the electrowetting display 20 is in a dark state, the display brightness is lowered, thereby improving the contrast of the electrowetting display 20 to display the kneading surface. 200921146 Referring to Figure 6, there is shown a cross-sectional view of a mine _ %〉 wet display in the second embodiment of the present invention.

Please refer to FIG. 7 , which is a schematic diagram of the cross section of the HF: device when the device is not in a dark state. The electrowetting display 4 is different from the first per-expanding electrowetting display 2 in that the electrowetting display (4) = the wall 49 includes a first insulating wall 491 and a second insulating wall. The insulation wall 491 is a light absorbing layer, and the second insulation wall 492 is a light transmission=. The second insulating wall 492 is disposed on the surface of the water repellent "48" of the electrowetting display 4. The first insulating wall 491 is wrapped on the side of the second insulating wall. (4) Figure 8 is the present invention. The electrowetting display of the fourth embodiment is not obscured. The electrowetting display 5 is different from the electrowetting display 20 of the first embodiment in that electrowetting displays $. The wall 59 is opaque as a whole; for example, the opaque material shape = isolated step 59' or carbon in the original light-transmitting insulating wall % can be directly used [to make the insulating wall 59 integrally form a light absorbing layer. . However, the features of the present invention can be applied not only to the above-described embodiments, but also to appropriate changes as needed. For example, the first insulating wall may be disposed at other positions of the insulating wall 'eg, disposed in the middle of the insulating wall; 11 200921146 The insulating wall with the light absorbing layer may also be applied to total reflection or half-through and vice versa The wet display is not limited to the above embodiment; and the above-mentioned total reflection or half-through and half-electrolytic display state can be formed by forming a reflective electrode.
