In the present embodiment, the bump structure 32! and the groove structure 341 are cylindrical, but not limited thereto, and the size of each of the bump structures 32! and each of the groove structures 341 can substantially cover two times. The range of the prime, one of the secondary scorpion 22 is used to provide the left eye face L, and the other pixel 22 is used to provide the right eye face r, but not limited thereto.里u The first and second % of the main lens 3 of the present invention, the second layer of the second layer, and the second layer of the film 201122555 have:: the picture produced by the rc'm panel 2〇 has a second scattering effect, and =====Continue...Shun down, at this time, the effect of the first shot - the first shot has a - second dispersion, & if the 疋 does not have a scattering effect or close to no scattering effect. The switchable scattering characteristic of the first film layer 32 or the second film layer 34 is achieved by driving an electric field, so the active scattering lens 3G further includes a first electrode and a second electrode 38. One film layer 32 is opposite the other side of the second film layer and the second film layer 34 is opposite the other side of the first film layer 32, thereby providing an electric field required to switch scattering characteristics. The first electrode 36 and the first The two electrodes 38 are transparent electrodes, but are not limited thereto. In the present invention, the switchable scattering characteristics of the first film layer 32 or the second film layer 34 are not limited to being realized by controlling the electric field, but may also be utilized. In the present embodiment, the first film layer 32 includes a liquid crystal layer having switchable scattering characteristics, such as a molecularly dispersed liquid crystal (p〇〗 ymerdispersed liquiderystal pDi^ layer, a polymer stabilized liquid crystal (polymer stabilized liquid crystal) Crystal, PSLC) layer, a polymer network liquid crystal (PNLC) layer, a polymer stabilized cholesteric liquid crystal (PSCLC) layer, or a combination thereof It is not limited to the above liquid crystal material, but may be other materials that can switch the scattering characteristics by electric field or other means. 201122555 As shown in Fig. 1, in the three-dimensional display mode, the first electrode 36 and the second electrode 38 The presence-electric field, and in the presence of an electric field, the active scattering lens 3g is in the first optical mode, at which time the first film layer 32 and the second layer 3 have no scattering effect on the human light. In the case, since the first refractive index of the first film layer 32 is different from the second refractive index of the second film layer 34, a lens effect is generated. Therefore, when the display panel 2 is provided, the left eyelid for viewing by the left eye is provided. When the face L and the right eye picture r for viewing by the right eye enter the interface of the first film layer 32 and the second film layer 34 of the active scattering lens 3G, refraction is generated, and the left eye face L and the right eye face r are divided. The left eye and the right eye of the axial viewer are displayed.

The liquid crystal material is limited, and it is also a material that can be controlled by electricity or otherwise controlled to exhibit/not exhibit scattering characteristics. '', as shown in Fig. 5, in the third mode, the mth and the There is no electric field between the two electrodes 38, and in the case of the electric field forest, the first_μ and the second film 34 have a _first scattering effect for human light, for example, there is no scattering effect or close to no scattering effect. Because the first - the third of the 32 - the refractive index and the second lining of the second refracting material, it will be red Wei Lai. Shame _ panel 2 〇 provided by the left eye to see the left eye 昼 无 无 Wei Wei Wei Wei昼(10) causes refraction at the interface of the first-film layer 32 and the second film layer of the active scattering lens 3〇, so that the left-eye pupil face L and the right-eye pupil face R face the viewer's left and right eyes, respectively. Direction display. As shown in FIG. 6, in the two-dimensional display mode, an electric field exists between the first electrode 36 and the second electrode 38 of 201122555, and in the presence of an electric field, the second film layer has a second scattering for human light. The effect 'and the first-scattering effect is lower than the second scattering effect. Under this circumstance, the second rib 34 is difficult to produce the ribs. @此# The left eye face L provided by the display panel 20 for the left eye and the right eye picture r for the right eye to enter the second film layer 34 of the active scattering lens 30 may be caused by the scattering effect. The left eye face L is mixed with the right eye picture r. Referring to FIG. 7 and FIG. 81h, FIGS. 7 and 8 are schematic diagrams of a display device capable of switching between a two-dimensional display mode and a three-dimensional display mode according to a further preferred embodiment of the present invention. FIG. 7 is a display device The schematic diagram in the three-dimensional display mode, and the eighth diagram is a schematic diagram of the display device in the two-dimensional display mode. As shown in Fig. 7, the material of the first layer 36 of the display device 7G of the present embodiment differs, and in the three-dimensional display mode, there is no electric field between the first electrode 36 and the second electrode 38. And in the absence of an electric field, the first film layer 32 and the second film layer 34 each have a first scattering effect on incident light, such as no scattering effect or near no scattering effect. Since the first index of refraction of the first film layer 32 is different from the second index of refraction of the second film layer 34, a transluminal effect is produced. Therefore, when the left eye picture provided by the display panel 20 for viewing by the left eye [the right eye face R for viewing by the right eye enters the interface of the first film layer 32 of the active scattering lens 3 and the first film layer 34, Refraction is generated such that the left-eye picture L· and the right-eye face R are displayed toward the left and right eyes of the viewer, respectively. As shown in FIG. 8, in the two-dimensional display mode, an electric field exists between the first electrode 36 and the second electrode 38, and in the presence of an electric field, the second film layer 34 has a second scattering effect on incident light. And the first scattering effect is lower than the second scattering effect. In this case, the dispersion produced by the second film layer 34 2011 22555 = will offset the lens effect. Therefore, when the f-eye surface L provided by the display panel 20 for viewing by the left eye and the right-eye surface R of the Wei viewing frame enter the active scattering lens 30, the left eye picture L is caused by the scattering effect. Mixed with the right eye picture R. As can be seen from the above, the display device of the present invention realizes a two-dimensional display mode by using a second wire provided by an active 2 lens having switchable scattering characteristics and a first optical mode. It is worth noting that the active scattering lens is active. It is not limited to the application on the display device. It can also be applied to other various optical applications. The active scattering transparent scattering side of the present invention has the effect of eliminating the effect of the second display, and has the interference of eliminating the display device. Now (4) utility, thus improving the quality. In addition, since the active scattering lens of the present invention only needs to utilize the electric field provided by the two electrode layers, (4) scattering Wei, without additionally setting a thicker switching element for two The display mode and the three-complement _ change, so the thickness of the display device of the present invention (4), in this case, the ageing device of the present invention can have a test under the three-dimensional display mode to increase the range of the display device Especially in the application of portable electronic products such as mobile phones, personal digital secrets, and other products with short viewing distances.
