New description: [New technical field] This creation side is a display device that can switch between two-dimensional display mode and three-axis display mode and its liquid crystal lens, especially the three-layer electrode drive crystal lens The display device of the switchable two-layer and three-display liquid crystal molecules. [Prior Art] The main principle of the stereoscopic display technology is that the left eye and the right eye of the viewer respectively receive different images, and the images of the left eye and the right eye are analyzed and overlapped by the brain to make the viewer perceive the display. The layering and depth of the kneading surface creates a three-dimensional effect. At present, the stereoscopic imaging technology on the market can mainly distinguish the time-sequential shot (four) #_. The day's pick-up red ugly reduction will be done by scanning _ showing the picture for the left eye and the right eye for the right eye. When viewing the screen, the viewer must wear the shutter glasses (10) to face the face, and the shutter glasses can allow the left eye of the viewer to view only the left eye image according to the currently displayed screen, and cannot view the right eye image, and allow The viewer's right eye only sees the right eye and can't see the effect of the left eye picture 'viewing the body'. The spatial multiplexed stereoscopic display device utilizes a liquid crystal lens disposed in the stereoscopic display device to refract the desired image of the left eye to the left _ direction and the right side of the right eye to be refracted to the right eye M395187 to 'three-dimensional Viewing effect. In addition, the stereoscopic display device using the liquid crystal lens enables the viewer to freely switch between the two-dimensional display mode and the three-dimensional display mode, so that it is more convenient and user-friendly in use. The liquid crystal lens of the lion is distributed in the liquid crystal layer to drive the liquid crystal molecules in the liquid crystal layer, so that the long axis of the liquid crystal molecules changes direction with the strength of the electric field, thereby achieving a lens-like lake structure. Silk, the double-layer electric φ pole driving method of the conventional liquid crystal lens, because the electric field distribution for driving is too simple, the liquid crystal molecules in the liquid crystal layer cannot be arranged close to the idealized lens, so that the liquid crystal lens is penetrated. The display pupil surface is also not fully refracted to the ideal direction (for example, the left eye and the right eye of the viewer), so the conventional liquid crystal lens still needs further improvement in its electric field distribution and design. [New content] The main purpose of this creation is to provide a 7F device that can switch between the two-display mode and the three-dimensional display mode and its liquid crystal lens. For the above purpose, the present invention provides a liquid crystal lens comprising a plurality of lens sheets/0, a first substrate, a second substrate disposed opposite to the first substrate, and a liquid crystal layer disposed on the first substrate and the second substrate.

The electrode layer includes a pair of second outer electrodes and a pair for the above purpose, and the present invention further provides a display device capable of switching between a two-dimensional display mode and a three-dimensional display mode, including a “display panel,” and the liquid crystal lens is disposed in the display Above the panel. The image image projected by the cap panel passes through the liquid crystal lens, and the field of the field is controlled by the electric field of the control ship, and the display of the dimensional display mode and the three-dimensional display mode is displayed. The device and its liquid crystal lens do not have any voltage difference between the liquid crystal lens-like first electrode layer and the second electrode layer and the third electrode layer, so that the liquid crystal molecules in the liquid crystal lens are not in the workplace. (4) The slanting system is used, so the liquid crystal lens does not depend on the scene projected by the panel. When the display device is in the three-dimensional display mode, the first electrode layer and the second electrode layer in the liquid crystal lens respectively have a voltage difference between the third electrode layer and the third electrode layer, so that the liquid crystal molecules of the liquid crystal lens are affected by the electric field generated by the voltage difference. An arrangement with a gradient change is presented. Therefore, when the image projected by the display panel passes through the liquid crystal lens, the liquid crystal molecules in the liquid crystal lens can refract the pupil surface provided to the left eye to the position of the left eye of the viewer and the face to be provided to the right eye. Refractive to the position of the viewer's right eye to achieve the viewing effect of the three-dimensional display.

The center portion of the outer electrode 32 and each of the second outer electrode 52 and each of the second inner electrodes 54 are not disposed in alignment with any of the ends of the first outer electrodes 32. This embodiment has more heavy electric field distribution than the first preferred embodiment described above. Since the second outer electrodes 52 and the second coffee makers 54 of the embodiment are not disposed at the two ends of the first outer electrodes 32, the second preferred embodiment is different from the first preferred embodiment. The liquid crystal molecules of both ends of the outer electrode 3 2 and the second electrode layer 7 G are mainly driven by the first outer voltage, not by the first outer voltage and the second outer voltage and the second inner rt. __. Therefore, she reads the crystallographic system in the lens unit LU of the first-preferred redistribution lens, and more of the electro-_ layer 33 () and the third electrode layer 7G and the second electrode layer % and third When i crystallizes 'and when the liquid crystal molecules are driven by multiple electric fields, it is closer to: = the change of direction can also show more levels of turning, to achieve the mirror ω 2 the first 3 calendars 3 'will show the creation Liquid crystal transmission of the third preferred embodiment: a schematic cross-sectional structure of a 1-tone. As shown in the fifth (f), the present invention is the liquid crystal lens of the preferred embodiment. The = 乍, 帛 _ electrode width, the ___ electrode width is generally M395187 between 2 microns and 30 microns, and preferably 1 G microns. Further, there is a pitch between each of the first inner electrodes 34 and its adjacent first outer electrode 32, the pitch being between 2 micrometers and micrometers, and preferably 5 micrometers. In this embodiment, the first outer electrode width is greater than the second outer electrode width, and the first inner electrode width is greater than the second inner electrode width, but is not limited thereto. In addition, in the first inner electrode 'and the first electrode layer 70 of the present embodiment, there is a -first-side voltage difference, and the first-inside voltage difference is generated in the first-outside electric house difference, but this is not Limit, the first inner electric difference may also be equal to the outer side voltage difference. The first inner voltage difference of this embodiment is between ^V and 100 volts' and preferably between 5 volts and 10 volts. Different from the foregoing embodiment, the second inner electrode 54 of the present embodiment is disposed at a central portion of the first inner electrode 34 in a vertical projection direction, and the second outer electrode is disposed at the first portion in a vertical projection direction. The central portion of the outer electrode 32, and the second outer electrode % is completely overlapped with the first outer electrode 32 in a vertical projection direction, and the second_electrode % is completely overlapped with the first inner electrode 34 in the vertical projection direction. In addition, the liquid crystal molecules between the portion where the first inner electrode 34 overlaps the second electrode 54 and the third electrode layer % are mainly driven by the electric field generated by the first inner voltage and the second inner voltage. . Compared with the foregoing embodiment, the present embodiment is provided by adding a pair of first inner electrodes 34 to the liquid crystal in the LU, and providing the first inner electrode % different from the first-inside voltage of the first-outer voltage. Providing more heavy electric field distribution and electric coupling, so that the long axis of the liquid crystal molecules in the liquid crystal layer 60 has more layers of turning, so that the lens unit LU of the liquid crystal lens 1 of the embodiment is closer to the action. In the lens M395187, a cross-sectional structural view of the lens unit LU of the liquid crystal lens K of the fourth preferred embodiment of the present invention is shown in FIG. As shown in FIG. 4, unlike the third preferred embodiment, the ends of the second outer electrodes 52 of the present embodiment are aligned with the vertical projections of the first outer electrodes 32, and It is disposed substantially at the edge close to both sides of the liquid crystal cell LU. The lens unit mountain of the liquid crystal lens (1) of the present embodiment overlaps the first outer electrode 32 and the second outer electrode by simultaneously providing the first outer electrode ^ and the second outer electrode 52 at the edges on both sides close to the liquid crystal single itLU. The liquid crystal molecules between the portion and the third layer 7G can be driven by an electric field generated by the second outer voltage of the first outer voltage plate. In order to achieve a structure close to the lens, the crystallographic molecular filament located at the edge of the liquid crystal cell LU requires a larger tilting amplitude than the long axis of the crystallographic molecule in other regions, so the long axis of the liquid crystal molecule driving the edge of the liquid crystal unit LU requires a strong electric field drive. The shame embodiment is provided by the second outer electrode 52 of the outer-side electrode to be disposed at the edge of the liquid crystal unit LU to achieve the function of enhancing the edge electric field driving: the lens unit Lu of the liquid crystal lens 1 of the present embodiment is also borrowed. By setting the first pole Μ to provide more heavy electric field distribution and electrode combination, the liquid raft in the liquid crystal layer 6 曰曰 can have a multi-level transition. The fifth riding shows the liquid crystal of the preferred embodiment. As shown in FIG. 5, the 'the outer side electrode 32 is adjacent to the adjacent first-outer electrode 32, and is formed by the same process step, but is not secreted, and is located in each lens unit LUiJ. Each of the first outer woven poles 32 may also be spaced apart from its adjacent edge. In addition, each of the first outer electrodes 52 of the respective lens units LU 彼此 is also connected to the first outer electrode 52 and the second outer electrode 52 of the phase 12 t, but is not limited thereto. The booklet shows a liquid crystal lens assembled by three lens units LU. In actual creation, the number of lens units LU is not limited thereto.
