Description of the Invention: [Technical Field] The present invention relates to a parallax barrier device suitable for switching between two-dimensional images and three-dimensional images. ^ · [Prior Art] The traditional 3D image display device mainly uses binocular disparity to achieve stereoscopic effect, that is, let the left and right eyes respectively accept plane images of different viewing angles, and utilize the brain's fusion function. To produce stereo vision. In commercial products, auto-stereoscopic displays do not need to be worn with glasses. The more commonly used method is parallax barrier or lenticular lens to make the left eye look only. To the left eye image, and the right eye to see the right eye image, spatial multiplexed. Figure 1 shows a conventional fixed parallax barrier. A parallax barrier 2 is set to φ placed in front of the 2D image display 4, and the viewer does not need to wear the auxiliary glasses. Due to the presence of the parallax barrier 2, the left eye only sees the left eye image l, while the right eye only sees! The right eye image R achieves the effect of displaying a stereoscopic image. This conventional fixed parallax barrier is only suitable for fixed 3D imaging and cannot be switched to 2D imaging. A 2D/3D switching type display device is disclosed in U.S. Patent No. 6,046,849. Referring to FIG. 2A, the conventional 2D/3D switching display device 10A includes a liquid crystal display panel u, a backlight module 13, a patterned half-wavelength plate 12, and a switchable rotor (switchabie I380Q54 - rotator). 15 and an outer polarizing plate 14, wherein the patterned half-wave plate 12 is divided into 12B whose optical axis is perpendicular to the optical axis of the outer polarizing plate 14, and 12A which is at an angle with the outer polarizing plate 14. The two states in which the switchable rotor 15 can be switched are: a state of a quarter wave plate and a state in which the polarization of the transmitted light is not affected. When the 3D image is displayed, the switchable rotor 15 is switched to a state that does not affect the polarization of the transmitted light. At this time, the polarization direction of the image passing through 12 people is rotated to pass through the outer polarizing plate 14 and pass through the 12B. The image will be blocked by the outer polarizing plate 14, so that the combination of the half-wavelength plate 12, the switchable rotor 15 and the outer polarizing plate 14 can be regarded as a parallax barrier. When the 2D image is displayed, the switchable rotor 15 is switched to a quarter-wave plate, so that the images of 12 a and 12 B are circularly polarized, and the external polarizing plate 14 can be used to achieve 2D development. Fig. 2B is a schematic view showing another conventional 2D/3D switching type display device. The structure is similar to 2 A except that the switchable rotor 15 in 2 A is replaced with a switchable diffuser 16. Switching the switchable diffuser 16 electrically to achieve 3D/2D image

The two states in which the switchable diffusion plate 16 can be switched are respectively a scattering state and a state in which the polarization of the transmitted light is not affected. When the 3D image is displayed, the switchable diffuser 16 is switched to a state that does not affect the polarization of the transmitted light. At this time, the polarization direction of the image passing through 12A is rotated to pass through the outer polarizing plate 14, and the image after 12B is to be The outer polarizing plate 14 is blocked, so that the combination of the half-wavelength plate 12, the switchable diffusing plate 16, and the outer polarizing plate 14 can be regarded as a parallax barrier. When the 2D image is displayed, the switchable diffuser 16 is switched to a scattering state, so that after 12A 7 Ι 38 〇ΰ 54 - and 12 Β❺ image polarization is aerated into a random state, a portion of the image can be reached through the outer polarizing plate 14 ' 2D imaging effect. SUMMARY OF THE INVENTION The present invention provides a liquid crystal-controlled patterned light valve, in which a polarized electrode layer of a pattern is adsorbed to an alignment substance, and light is applied in an area where the electric field is applied or not. If the function of the parallax barrier is turned on or off, the display module with the two-dimensional image can be Φ to achieve the image switching function. [Embodiment] Figs. 3A and 3B are schematic cross-sectional views showing the image switching device of the present invention in a voltage off state and an on state, respectively. Fig. 3A is a view showing a dark_party state of the area a and the b area of the light valve of the present invention. The patterned photoelectric switching element 100 includes a first substrate 110 and a second substrate 130. A first electrode 112 is formed on the first substrate 110 in a comprehensive manner, and a second electrode 132 is formed on the second substrate 13A in a comprehensive manner. The first electrode 112 and the second electrode 132 are exemplified by Indium Tin Oxides (IT0), which is subjected to a patterned surface treatment in the region A, such as an oxygen plasma treatment 'according to the reference'. Indium tin oxide by plasma treatment: An effective method to improve the efficiency, brightness, and reliability of organic light emitting devices" Appl. Phys. Lett. 70, 17, (1997), the surface of indium tin oxide treated by oxygen plasma The concentration of tin atoms decreases, the concentration of oxygen atoms rises, and a polar oxygen 1380054 - indium tin (polar ιτο) surface is formed in region A, and a plurality of spaced-apart "polar electrodes" are formed on the surface of the indium tin oxide electrode layers i12, 132. Layer" (Zone A) and another set of ITO (Zone B) that have not been surface treated. The liquid crystal layer 120 of the present embodiment is a mixed solution containing the negative liquid crystal molecules 121 and the alignment material 122, wherein the alignment material 122 is a material having polarity - such as polyhedral oligomeric silsesquioxanes (POSS). Or a derivative thereof which is adsorbed to the polar electrode layer (region A) to form a plurality of spaced-apart aligning electrical φ pole layers 113, 133 of the present embodiment, preferably in a parallel spaced configuration. An alignment effect is produced on the liquid crystal molecules 121. Fig. 3A shows that the liquid crystal molecules (region A) interposed between the alignment electrode layers 113, 133 naturally appear aligned neatly to the upper and lower substrates, however, the liquid crystal molecules are not aligned in the region B'. In order to achieve the photoelectric element switching effect, polarizing plates 105 and 135 whose optical axes are perpendicular to each other are attached to the outside of the first substrate 110 and the second substrate 130 of the active photoelectric switching element. Since the liquid crystal molecules in the liquid crystal layer of the region A are arranged neatly, the polarization direction of the incident light is not changed, and the incident light cannot pass through the second polarizing plate, thereby presenting a dark state to the observer. However, in the region B, the liquid crystal molecules are disorderly arranged to change the polarization direction of the incident light, so that the incident light portion can pass through the second polarizing plate and thus exhibit a bright state. In Fig. 3B, the light valve A area and the B area of the present embodiment respectively show a bright-light state. When a threshold voltage greater than the threshold voltage of the liquid crystal molecules is applied to the electrode layers 112, 132, the liquid crystal molecules of the regions A and B are aligned parallel to the arrangement of the upper and lower substrates to rotate the polarization direction of the incident light, resulting in the photoelectric switching element. All areas are in a bright state, that is, I380Q54' is the light of both area A and area B, as shown in Figure 3B. This characteristic area allows light to pass and fail, allowing it to be enabled or disabled as a parallax barrier. The photoelectric switching element of this embodiment can be further combined with other types of optical plates 'e.g., circularly polarized polarizing plates or phase-compensation films' to enhance optical performance and to respond to different types of applications. 4A and 4B are cross-sectional views showing the image switching device in a voltage off state and an on state, respectively, according to another embodiment of the present invention. Fig. 4A is a view showing a shell-dark state of the light valve A area and the B area of the present embodiment, respectively. The structure of the image switching device 2A in FIG. 4A is substantially similar to the image switching device 1 in FIG. 3A, except that the material of the liquid corrugated layer 220 is a guest crystal (Guest/h).混合st liquid crystal) A mixed solution containing a mixed solution of a positive liquid crystal molecule 221, an alignment substance 222, and a dichroic dye molecule 223. The region A of the first electrode 212 and the second electrode 232 is surface-treated to have a polar electrode layer in the surface region, and the alignment substance 222 is adsorbed on the surface of the polar electrode layer. In this embodiment, a plurality of spaced-apart alignment electrode layers 213, 233 are formed between the upper and lower layers, preferably in a parallel spaced pattern. At this time, the liquid crystal molecules interposed between the alignment electrode layers 213 and 233 and the dichroic dye are naturally arranged neatly, however, in the region B, the liquid crystal molecules and the dichroic dye molecules are not aligned. Since the liquid crystal molecules in the liquid crystal layer of the region A are aligned with the dichroic dye molecules perpendicularly to the upper and lower substrates, the dichroic dye molecules do not absorb the incident light, that is, the light can pass through the state of 10' and thus present a bright state. . However, in the region B, the liquid crystal molecules and the dichroic dye molecules are not aligned to absorb the incident light, that is, the state in which the light is impermeable, and thus the dark state is exhibited. In Fig. 4B, the light valve a area and the b area of the present embodiment respectively show a bright-light state. The rich one is greater than the threshold voltage of the liquid crystal molecules on the electrode layers 212, 232, and the liquid crystal molecules of the regions A and B and the dichroic dye molecules are aligned perpendicularly to the upper and lower substrates, resulting in all of the photoelectric switching elements. The regions all show a bright state, that is, the light of both region A and region B can pass, as shown in Fig. 4B. 5A and 5B are cross-sectional views showing the image switching device according to another embodiment of the present invention in a voltage off state and an on state, respectively. Fig. 5A shows a light-bright state of the light valve A area and the B area, respectively, in the present embodiment. The image switching device 300 includes a first substrate 310 made of polyethylene terephthalate and a second substrate 330 of the same or different materials. A patterned electrode layer 312 and 332 are respectively formed at 310. , area a of 330. The alignment electrode layers 313 and 333 are formed on the surfaces of the electrode layers 312 and 332, respectively. The liquid crystal layer 320 is a mixed solution containing the negative liquid crystal molecules 321 and the alignment material 322. The alignment material 322 can be adsorbed on the region A, and a plurality of spaced-apart alignment electrode layers 313 and 333 are formed between the upper and lower layers, preferably in parallel. The type of interval exists. The liquid crystal molecules interposed between the alignment electrode layers 333 and 313 are naturally aligned neatly perpendicular to the upper and lower substrates, however, in the region B, the liquid crystal molecules are not aligned. In order to achieve the photoelectric element switching effect, polarizing plates 305 and 335 whose optical axes are perpendicular to each other are attached to the outside of the first substrate 310 and the second substrate 330 of the active I380Q54 - photoelectric switching element. Since the liquid crystal molecules of the region A are aligned perpendicularly to the upper and lower substrates, the polarization direction of the incident light is not changed, and the incident light cannot pass through the second polarizing plate, thereby presenting a dark state to the observer. However, the liquid crystal molecules in the region B' are not aligned and change "the polarization direction of the incident light' so that part of the light can pass through the second polarizer to present a bright state. In Fig. 5B, the light valve a area and the B area of the present embodiment respectively exhibit a φ bright-bright state. When a liquid crystal molecule which is larger than the liquid crystal molecule starting voltage (Thresh〇ld voltage) on the electrode layer 312, 332 is aligned in parallel with the upper and lower substrates to exhibit a bright state, the region A will be caused. Simultaneously appearing with region B, as shown in Figure 5B.
