Polymer-dispersed liquid crystal (PDLC) is an attractive electro-optic medium, and optical switches, phase modulators, electronic lenses, and displays have been extensively studied. In PDLC systems, liquid crystals (LC) usually form micron-sized droplets randomly dispersed in a polymer matrix. In order to form a PDLC, several factors such as curing temperature, UV intensity, and materials used can simultaneously affect the phase separation morphology during the phase separation process.

In addition, the existing three-dimensional stereoscopic display device is generally made by the technology of binocular fusion image. Generally, the naked-view three-dimensional stereoscopic display device needs to allow the user to view the stereoscopic image in the direction facing the display device, while the stereoscopic image cannot be displayed in the direction not facing the display device. When considering the situation of some situations, such as aerial terrain model, architectural model, medical 3D training, etc., when the display device is placed horizontally, the viewer's natural angle of view is to obliquely view the display device. At this time, the mainstream three-dimensional display technology cannot provide a natural viewing angle for the viewer, which causes inconvenience. In addition, for a general three-dimensional stereoscopic display device, the 3D perception viewed from the front is a visual stimulus in only one direction for the viewer, just like the picture is protruding or sinking. It can't achieve the feeling of really making the image out of the plane.

Therefore, how to use the polymer dispersed liquid crystal (PDLC) to form a microstructure layer for adjusting the angle direction of light to overcome the above-mentioned defects has become one of the important issues to be solved by this business.

The liquid crystal mixed layer includes a base material and a liquid crystal material dispersed in the base material. The light emitting module is used to provide at least one control light source to the photoconductor array layer, so that the photoconductor array layer generates at least one control voltage. Wherein, the control circuit is configured to output at least one first driving voltage to the first electrode array layer, and control the light emitting module to generate at least one control light source, so that the first electrode array layer and the photoconductor array layer form the first in the liquid crystal mixed layer An electric field distribution makes the liquid crystal mixed layer phase separate to form a plurality of first microlens structures.

[First embodiment]

Please refer to FIGS. 1 and 2 together. FIG. 1 is a schematic diagram of a light control module according to a first embodiment of the present invention. FIG. 2 is a schematic diagram of a voltage control and light source control microlens structure according to a first embodiment of the present invention. Referring to FIG. 1, the first embodiment of the present invention provides a light control module 1 including an upper substrate 10, a lower substrate 11 opposite to the upper substrate 10, and a liquid crystal mixed layer between the upper substrate 10 and the lower substrate 11 12. The first electrode array layer 13 provided on the lower substrate, the control circuit 14 electrically connected to the first electrode array layer 13, the photoconductor array layer 15 provided on the lower substrate, and the electrical connection of the control circuit 14 Light emitting module 16.

The upper substrate 10, the lower substrate 11, the first electrode array layer 13 and the photoconductor array layer 15 can be made of transparent materials, for example, the upper substrate 10 and the lower substrate 11 can be made of organic glass (PPMA), polycarbonate (PC), Made of transparent materials such as polyethylene (PE) or glass (Glass), the first electrode array layer 13 can be made of transparent electrode materials including AZO and ITO, and the photoconductor array layer 15 can be made of polymer polyethylene carbazole It is made of (poly vinylcarbazole, PVK) so that light from the outside can enter the liquid crystal mixed layer 12 from the upper substrate 10 or the lower substrate 11.

In detail, the liquid crystal hybrid layer 12 includes a base material 120 and a liquid crystal material 122 dispersed in the base material 120, and the light emitting module 16 is used to provide a control light source 160 to the photoconductor array layer 15 so that the photoconductor array layer 15 generates a control voltage Vc.

On the other hand, the control circuit 14 may include a power converter configured to output a first driving voltage V1 to a portion of the first electrode array layer 13 to form a potential difference between different first electrode array layers 13 while In addition, the control circuit 14 may further include one or more processors for controlling the light emitting module 16 to generate the control light source 160. The processor may be a programmable unit, such as a microprocessor, microcontroller, digital signal processor (DSP) chip, field-programmable gate array (FPGA), etc. The functions of the processor can also be implemented by one or several electronic devices or ICs. In other words, the functions performed by the processor can be implemented in the hardware domain or the software domain or a combination of the hardware domain and the software domain.

According to an embodiment of the present invention, the liquid crystal mixed layer 12 uses a phase separation composite film (PSCOF) technology to prepare a multilayer structure, for example, perpendicular to the substrate to form an electrically controllable microlens structure, which will be generated according to the applied voltage The adjacent uniform layer of the liquid crystal material 122 and the base material 120. In addition, the microlens structure formed by the liquid crystal material 122, in which the optical axis configuration can be controlled by the alignment film on the lower substrate 10 closest to the liquid crystal mixed layer 12, and the operation of the phase separation composite film (PSCOF) device responds to the application The electric field produces birefringent changes.

In this embodiment, the liquid crystal material 122 may include nematic liquid crystals. Such liquid crystals are free of smectic liquid crystals and relatively easy to flow. Generally, when heated to a higher temperature, the smectic substance is converted Line up substances. In the linear liquid crystal, each side-by-side molecule can slide on each other besides rotating itself. This type of liquid crystal has a linear structure because the interface between different regions reflects light. This type of liquid crystal is the first liquid crystal to be used, which is commonly found in LCD TVs, laptop computers, and various types of display components. The nematic liquid crystal may include BL series nematic liquid crystals, such as BL038, BL003, and BL006. On the other hand, the base material 120 may include a photo-curable polymer, such as NOA65 manufactured by Norland Optical Adhesive And NOA81.

Among them, the liquid crystal material 122 and the base material 120 are both dielectric materials, but have different dielectric constants. Therefore, in this embodiment, the molecules of the liquid crystal material 122 are treated as particles, and the monomer of the matrix material 120 is treated as a surrounding medium, and phase separation can be performed by providing a non-uniform electric field. At the initial stage, as shown in FIG. 1, the mixture including the liquid crystal material 122 and the base material 120 is filled between the upper substrate 11 and the lower substrate 10 in an isotropic state, and due to partial phase separation, the liquid crystal material 122 in the solvent Can maintain isotropic state or form droplets.

Next, as shown in FIG. 2, first, the first driving voltage V1 may be supplied to the first electrode array layer 13. When a voltage is applied to the first electrode array layer 13, the fringe field generated is not uniform. The fringe electric field near the first electrode array layer 13 has a gradient, but the electric field is relatively uniform between the two electrodes of the first electrode array layer 13. As a result, the liquid crystal material 122 and the base material 120 are respectively pushed by the uneven electric field, thereby causing displacement.

Since the liquid crystal material 122 used has a larger dielectric constant than the liquid monomer of the base material 120, that is, ε _{liquid crystal} >ε _matrix , according to the Kelvin polarization force (Kelvin polarization force), the liquid crystal molecules in the liquid crystal material 122 will Withstand the greater force from the electric field. In this case, the liquid crystal molecules are forced to move to the high electric field region, and the liquid monomer is pushed to the weak electric field region, as shown in Figure 2. When the phase separation is completed, due to the existence of the fringe field, the liquid crystal mixed layer 12 may be phase separated to form a plurality of first microlens structures ML stably. However, if the voltage is removed, this balance will collapse and the liquid crystal molecules will redistribute in the monomer solvent.

In order to generate such an electric field, the fringe field generated by the first electrode array layer 13 and the photoconductor array layer 15 is used, and the first electric field distribution E1 shown in the figure controls the form of liquid crystal phase separation. As shown in the figure, a glass substrate may be used as the upper substrate 11 and the lower substrate 10, and the first electrode array layer 13 may be composed of indium tin oxide (ITO) electrodes, and the photoconductor array layer 15 may include a photoconductive material, such as PVK, And is located on the surface of the lower substrate 10, and the first electrode array can be formed by, for example, an interdigitated strip etching process 层13和光光阵阵层15。 Layer 13 and the photoconductor array layer 15.

Among them, the photoconductor array layer 15 has photoconductivity. Specifically, "photoconductivity" means the process of absorbing electromagnetic radiation energy so that the carrier can be conducted in a material, that is, transporting electric charges. "Photoconductor" and "photoconductive material" in the present invention mean semiconductor materials that are selected to absorb electromagnetic radiation of specific spectral energy to generate charge carriers.

Therefore, similarly, the light source module 16 can provide the light source 160 to control the charge carriers on the surface of the photoconductor array layer 15 to form a non-uniform electric field distribution, thereby controlling the phase separation of the liquid crystal mixing layer 12 to form a stable A micro lens structure ML. When the voltage is turned on and the light source 160 is turned on, the first electrode array layer 13 and the photoconductor array layer 15 form the first electric field distribution E1 in the liquid crystal mixed layer 12. At this time, the liquid crystal material 122 in the liquid crystal mixed layer 12 The droplets are assembled by the fringe field to form the first microlens structure ML, which may be, for example, a stripe array. By turning off the voltage and adjusting the light source 160, the first microlens structure ML can be broken into droplets again. And under this architecture, the droplet shape changes from droplet to lens array, or from lens array to droplet, both provide a reasonable response speed. The light control module of the present invention has a switching mechanism from a droplet to a lens array. Among them, the type of microlens structure formed by polymer dispersed liquid crystal can be adjusted through voltage control and light source control. The formed microlens structure can be used for Improve the display uniformity of the display device, at the same time used to achieve a three-dimensional display architecture.

Please refer to FIG. 3, which is another schematic diagram of the light control module according to the first embodiment of the present invention. As shown in the figure, in order to adjust the direction of the optical axis of the microlens structure, the light control module 1'may be further provided with a second electrode array layer 17, wherein the control circuit 14 may output a second driving voltage to the second electrode array layer 17 V2, the first electrode array layer 15, the second electrode array layer 17 and the photoconductor array layer 15 form a second electric field distribution E2 in the liquid crystal mixed layer 12, and the liquid crystal mixed layer 12 is separated to form a plurality of second microlens structures ML', wherein the optical axis O1 of the first microlens structure ML and the optical axis O2 of the second microlens structure ML' face different directions.

In addition, the control circuit 14 can also adjust the magnitude of the first driving voltage V1, To control the refractive index of the plurality of first microlens structures ML, or by adjusting the magnitude of the second driving voltage V2, to control the refractive index and optical axis direction of the plurality of second microlens structures ML'. In other words, the operation mode can refer to FIG. 4, which is a schematic diagram of the operation of the light control module according to the first embodiment of the present invention.

Among them, under no voltage application, through different voltages, such as the combination of the first driving voltage V1 and the second driving voltage V2, the first microlens structure ML with the optical axis O1 can be generated in FIG. 4 or the optical axis can be generated O2's second microlens structure ML', in this way, can control the light incident on the optical lens module to be refracted to guide the light to a deflected angle. On the other hand, by adjusting the magnitudes of the first driving voltage V1 and the second driving voltage V2, the refractive indexes of the first microlens structure ML and the second microlens structure ML' can be further controlled, and thus can be used to adjust the uniformity of the display device .

The light emitting module 204 includes a plurality of light emitting devices 204(i, j) corresponding to the plurality of pixels Px, respectively.

The second switching transistors 202(i, j) are connected to the control circuit 24 through the second driving signal lines S'(1), S'(2), ..., S'(N), and each second switch The control terminal of the transistor 202(i,j) is connected to the control circuit 24 via the second switch signal lines G'(1), G'(2), ..., G'(M).
