Additional aspects and advantages of the embodiments of the present invention will be given in part in the following description, part of which will become apparent from the following description, or be learned through the practice of the present invention.

Hereinafter, embodiments of the present invention will be described in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.

Referring to FIG. 1, a light control sheet 10 according to an embodiment of the present invention includes a light control layer 12 and a conductive film block 14. The light control layer 12 includes at least two light control regions 122. At least two pairs of conductive film blocks 14 correspond to at least two dimming regions 122. Each pair of conductive film blocks 14 is disposed on both sides of the corresponding light adjustment region 122 and can independently adjust the light transmittance of the corresponding light adjustment region 122 after an operating voltage is applied.

That is to say, each dimming region 122 corresponds to a pair of conductive film blocks 14, and the corresponding conductive film blocks 14 are respectively disposed on two sides of one dimming region 122. The pair of conductive film blocks 14 can apply an operating voltage to the corresponding dimming region 122, thereby forming an electric field passing through the dimming region 122.

The dimming method according to the embodiment of the present invention can be used for the dimming sheet 10. The dimming method includes the following steps:

The working voltage of the corresponding pair of conductive film blocks 14 is controlled to be applied or disconnected to independently adjust the light transmittance of the corresponding dimming region 122.

The control device provided in the embodiment of the present invention can be used to control the dimming sheet 10. The control device includes a control module. The control module is used to control the application or disconnection of the working voltage of the corresponding pair of conductive film blocks 14 to adjust the light transmittance of the corresponding dimming area 122.

Please refer to FIG. 1 and FIG. 11 together. The dimming sheet 10 according to the embodiment of the present invention can be used in an electronic device 100. The electronic device 100 includes one or more processors 20, a memory 30 and one or more programs 32. One or more programs 32 are stored in the memory 30 and are configured to be executed by the one or more processors 20. The program 32 includes instructions for executing the dimming method of the foregoing embodiment.

The storage medium according to the embodiment of the present invention stores one or more programs 32 executable by the processor 20. When the one or more programs 32 are executed by the processor 20, the steps in the dimming method of the above embodiment are implemented. The storage medium can be read by a computer.

According to the embodiment of the present invention, the dimming sheet 10, the dimming method, the control device, the electronic device 100 and the storage medium are provided with at least two pairs of conductive film blocks 14 on both sides of the dimming area 122, and each pair of conductive film blocks 14 can be independent The operating voltage of the corresponding dimming region 122 is applied or disconnected to adjust the light transmittance of the dimming region 122 without affecting the operating voltage of the adjacent dimming region 122. In this way, the dimming sheet 10 can implement local dimming to be applied to more occasions.

Specifically, when the dimming sheet 10 is in operation, a pair of conductive film blocks 14 at a certain position independently applies an operating voltage to a dimming region 122, and the liquid crystal molecules in the dimming layer 12 are aligned neatly under the action of an electric field. 12 changes from a low light transmittance to a high light transmittance, that is, the dimming sheet 10 is in a transparent state. The conductive film block 14 at other positions does not apply the operating voltage to the light adjustment region 122, the liquid crystal molecules in the light adjustment layer 12 are disorderly arranged, and the light adjustment layer 12 maintains low light transmittance, that is, the light adjustment sheet 10 is in an atomized state. That is, a part of the dimming sheet 10 is in a transparent state and a part is in an atomized state as a whole, and the transparent region and the atomized region can be freely combined to form a pattern. In this way, the light transmittance of the dimming sheet 10 at different positions can be changed by changing the operating voltage applied to the dimming area 122 corresponding to the conductive film block 14, so that it can be applied to more occasions.

It can be understood that the dimming sheet 10 and the electronic device 100 can be applied to various windows (such as floor-to-ceiling windows, car windows), and can also be used as indoor screens or glass curtain walls of buildings. The dimming sheet 10 can also be applied to a projection display, an optical modulator, a light valve, and the like.

In some embodiments, the light control layer 12 includes two substrates and a liquid crystal and a polymer filled between the two substrates. It can be understood that the dimming layer 12 is made of a mixture of liquid crystal and a polymer. The liquid crystal has a refractive index similar to that of a polymer when an operating voltage is applied, so the light control layer 12 is transparent. The liquid crystal has a large difference from the refractive index of the polymer when the operating voltage is turned off, so the light-adjusting layer 12 exhibits an atomized state. It can be understood that the atomized state is milky white, and the transparent state is also called an opaque state.

In some embodiments, the polymer may be a polyurethane acrylate (PUA). The use of polyurethane acrylate (PUA) can reduce the threshold voltage of the dimming layer 12, so that the dimming sheet 10 has high working efficiency and energy saving.

It can be understood that the light transmittance of the light control layer 12 is related to the working voltage applied by the conductive film block 14 across the light control region 122. Take the technical index of a liquid crystal dimming film as an example. The liquid crystal dimming film has an operating voltage of 18V to 75V. A light transmittance higher than 75% is called a transparent state, and a light transmittance lower than 2% is called an atomized state. That is to say, when the voltage applied by the conductive film block 14 is lower than a certain threshold value (18V), the light transmittance of the light adjusting sheet 10 is lower than 2%, so the light adjusting sheet 10 is in an atomized state. When the voltage applied by the conductive film block 14 is higher than a certain critical value (75V), the light transmittance of the light adjusting sheet 10 is higher than 75%, so the light adjusting sheet 10 is in a transparent state. When the voltage applied by the conductive film block 14 is between 18V and 75V, the larger the operating voltage is, the larger the light transmittance of the dimming sheet 10 is.

In some embodiments, the substrate may be glass or a film. When the substrate is glass, the light control sheet 10 is a light control glass. Dimmable glass can be applied to various windows. In other embodiments, the glass may be double-layered glass, and the dimming sheet 10 is disposed between the double-layered glass. In this way, the glass device provided with the dimming sheet 10 can also achieve local dimming. When the substrate is a film, the light control sheet 10 is a light control film with good flexibility. In this case, the dimming sheet 10 can be applied to a flat surface or a curved surface. In addition, dimming films can also be used in combination with glass. The dimming film can be attached to one side of the glass.

In some embodiments, the substrate may also be a PC board (the main component is polycarbonate). PC board has high light transmittance and high hardness. In this way, the support strength of the light control sheet 10 can be enhanced.

In the embodiment of the present invention, the dimming layer 12 has a continuous structure of a whole layer, that is, the liquid crystal and the polymer in adjacent dimming regions 122 are actually connected, and there is no substantial physical separation. In this way, the entire light adjusting sheet 10 can change the light transmittance when the working voltage is applied to the conductive film block 14.

In other embodiments, the dimming area 122 can be produced according to user requirements by adding a physical interval so that the dimming area 122 has a different shape and size. For example, for a dimming sheet 10 having a special pattern (such as a rose flower), when a dimming area 122 is correspondingly arranged in the shape of a petal, the shape and size of the dimming area 122 can be adjusted by spacing the dimming area 122 different.

In the embodiment of the present invention, the conductive film blocks 14 located on the same side of the light control layer 12 are discontinuously distributed, that is, adjacent conductive film blocks 14 on the same side of the light control layer 12 are separated from each other. Spaces are separated by gaps to avoid conduction.

In some embodiments, the physical shape of the conductive film block 14 corresponds to the shape of the corresponding dimming region 122 after adding a physical space inside the dimming layer 12 to form a specific shape of the dimming region 122. It can be understood that the corresponding meaning of the embodiments of the present invention means that the shapes are the same or similar. That is, the shape of the conductive film block 14 corresponds to the shape of the light control region 122.

In some embodiments, the orthographic projection of the conductive film block 14 in the corresponding dimming region 122 falls within the corresponding dimming region 122. It can be understood that, since the adjacent conductive film blocks 14 on the same side of the light control layer 12 need to avoid conduction, the pair of conductive film blocks 14 are disposed on both sides of the light control region 122 and on the same side of the light control region 122 The conductive film blocks 14 are spaced. That is, the size of the conductive film block 14 is smaller than the size of the dimming area 122.

Further, the size of the conductive film block 14 corresponds to the size of the corresponding dimming area 122. It can be understood that the size of the conductive film block 14 is related to the size of the dimming area 122. In order to make the pair of conductive film blocks 14 substantially cover one dimming region 122 and form an electric field passing through the dimming region 122 when a voltage is applied. The conductive film block 14 according to the embodiment of the present invention is slightly smaller than the dimming area 122.

The material of the conductive film block 14 is a transparent conductive material to meet the requirements of light transmission on both sides of the light adjusting sheet 10. Transparent conductive materials that can be used include indium tin oxide (ITO), nano-silver wires, metal mesh, nano-carbon tubes, graphene, and the like.

Please refer to FIG. 2. In some embodiments, the dimming sheet 10 further includes a transparent touch sensor 16 and a controller 18. The transparent touch sensor 16 corresponds to at least two pairs of conductive film blocks 14. The transparent touch sensor 16 is disposed on the conductive film block 14.

The controller 18 is connected to the transparent touch sensor 16 and the plurality of conductive film blocks 14. The controller 18 is used to control the application or disconnection of the operating voltage of the corresponding one or more pairs of conductive film blocks 14 when the transparent touch sensor 16 detects a touch, so as to adjust the light transmission of the corresponding light adjustment region 122 rate.

It can be understood that the touch area 162 is formed on the transparent touch sensor 16. The touch area 162 can be used to detect a touch track of a touch on the transparent touch sensor 16. It can be understood that the conductive film block 14 corresponds to the touch area 162. When the touch area 162 recognizes a touch action, the touch area 162 converts the touch signal into a coordinate signal and transmits it to the controller 18. The controller 18 receives the coordinate information and determines the position of the conductive film block 14 corresponding to the coordinates. The controller 18 then controls the conductive film block 14 to apply or disconnect the operating voltage of the corresponding dimming area 122, thereby adjusting the light transmittance of the dimming area 122. In this way, the touch control is used to implement local dimming of the dimming sheet 10.

Please refer to FIG. 2 again. In some embodiments, the dimming sheet 10 further includes an optically transparent adhesive layer 1 a adhering the transparent touch sensor 16 and the conductive film block 14.

It can be understood that the transparent touch sensor 16 is adhered to the dimming layer 12 through the optical transparent adhesive layer 1a. The optically transparent adhesive layer 1a may be a liquid non-conductive adhesive such as an epoxy resin adhesive. The optical transparent adhesive layer 1 a has a high light transmittance, and does not affect the light transmittance of the light control sheet 10.

In some embodiments, the transparent touch sensor 16 may be a flexible transparent touch sensor. In this way, the dimming sheet 10 can be applied to a flat surface or a curved surface. When the transparent touch sensor 16 is a flexible transparent touch sensor, the transparent touch sensor 16 can be attached to the conductive film block 14 in the form of a whole surface through the optical transparent adhesive layer 1a, that is, a sheet The thin film transparent touch sensor 16 may correspond to a plurality of dimming regions 122 (for example, one thin film transparent touch sensor 16 corresponds to nine dimming regions 122). In this way, the step of cutting the large-area transparent touch sensor 16 into a small unit area transparent touch sensor 16 is omitted.

It can be understood that the transparent touch sensor 16 according to the embodiment of the present invention may be a resistive transparent touch sensor or a capacitive transparent touch sensor, or may be an ultrasonic transparent touch sensor. For different transparent touch sensors 16, the corresponding conductive film block 14 and the controller 18 are adjusted accordingly. For example, the ultrasonic transparent touch sensor may use a piezoelectric element (such as a ceramic piezoelectric element). The piezoelectric element has a small volume, and can be attached to the dimming layer 12 in a matrix arrangement, and corresponds one-to-one with the conductive film block 14.

Please refer to FIG. 2 and FIG. 3 together. Now, the distribution of the conductive film block 14 on the dimming sheet 10 will be described using ITO as an example. The dimming sheet 10 includes a flexible circuit board 11, leads 13, and a frame 15. The conductive film blocks 14 are arranged on the dimming layer 12 in a matrix form, and correspond to the dimming area 122 and the transparent touch sensor 16. Each conductive film block 14 is connected to the flexible circuit board 11 through a lead 13. The flexible circuit board 11 is connected to the controller 18. In some embodiments, the leads 13 can be crimped into the flexible circuit board 11 to receive the leads 13. The frame 15 can prevent the peripheral edges of the dimming sheet 10 from being worn, and can also prevent the material on the dimming layer 12 from leaking out and play a role of insulation protection.

Further, the larger the number of the conductive film blocks 14 arranged per unit area, the finer the light transmission state of the light adjustment sheet 10 can be adjusted.

In order to make a person skilled in the art more clearly how to demodulate the light sheet 10 to realize local light adjustment of the light control sheet 10 through a touch operation, an embodiment combining the light control sheet 10 and a light control method will be specifically described below. .

The dimming method provided by the embodiment of the present invention can be used for the dimming sheet 10. The dimming method includes the following steps:

S10: Control the application or disconnection of the corresponding one or more working voltages of the conductive film block to independently adjust the light transmittance of the corresponding dimming area.

The dimming method of the embodiment of the present invention is adjusted by providing a pair of conductive film blocks 14 on both sides of the light control region 122, and each pair of conductive film blocks 14 can independently apply or disconnect the operating voltage of the corresponding light control region 122 to adjust The light transmittance of the light control region 122 does not affect the operating voltage of the adjacent light control region 122. In this way, the dimming sheet 10 can implement local dimming to be applied to more occasions.

In some embodiments, the dimming sheet 10 further includes a transparent touch sensor 16 and a controller 18.

Please refer to FIG. 4. Correspondingly, before step S10, the dimming method further includes the following steps:

S12: Detect a touch track of a touch on the dimming sheet;

S14: determine the touch track; and

S16: Determine the conductive film block corresponding to the touch track.

It can be understood that the detection function can be implemented by the transparent touch sensor 16, and the judgment and determination functions can be implemented by the controller 18.

The touch trajectories detected by the transparent touch sensor 16 can be divided into various types. If it is a continuous trajectory, the touch trajectory can be divided into an open trajectory (the starting point and the end point do not coincide) and a closed trajectory (the starting point and the end point are coincident without interruption points). Such as specific touch trajectories, touch trajectories can also be divided into directional trajectories (touch trajectories in a specific direction) and characteristic trajectories (set recognizable touch trajectories, such as numbers or the length of touch trajectories). It can be understood that after the transparent touch sensor 16 detects the touch track, the light adjusting sheet 10 needs to determine the type of the touch track first. After the type of the touch track is determined, the conductive film block 14 corresponding to the touch track is determined.

In the following, the dimming methods corresponding to various touch trajectories are taken as examples to further explain the specific content of each step in the dimming method of the dimming sheet 10. 5 (a), 5 (b), 5 (c), and 5 (d) are four embodiments of the light adjusting sheet 10.

Referring to FIG. 6, in some embodiments, the touch track includes an open track. The following steps are included after step S12:

S142: Determine that the touch track is the open track;

S162: Determine a conductive film block corresponding to the open track;

S102: Control the application or disconnection of one or more working voltages of the conductive film block corresponding to the open track to adjust the light transmittance of the corresponding dimming area.

See Figure 5 (a). FIG. 5 (a) is a schematic diagram of a touch track detected by the dimming film 10. Specifically, the touch area 162 detects the touch track in real time, and determines the coordinates of the touch track. The controller 18 processes the coordinate information and determines a complex dimming area 122 corresponding to the coordinates. Specifically, when the controller 18 controls the conductive film block 14 to apply a working voltage to the corresponding dimming region 122, the light transmittance of the dimming region 122 becomes larger, that is, the dimming sheet 10 is in a transparent state. That is to say, when the user touches the touch area 162, the light transmittance of the corresponding dimming area 122 changes, which manifests itself as the dimming sheet 10 becomes transparent following the movement of the finger position, and the dimming corresponding to the coordinates is not. The light sheet 10 remains in the original atomized state.

In this way, the dimming sheet 10 in a part of the area can follow the touch track to show a transparent state.

When the controller 18 controls the conductive film block 14 to turn off the operating voltage of the corresponding dimming area 122, the light transmittance of the dimming area 122 becomes smaller, that is, the dimming sheet 10 is in an atomized state. That is to say, when the user touches the touch area 162, the light transmittance of the dimming area 122 at the corresponding position changes, and the dimming sheet 10 follows the movement of the finger position to be in an atomized state, which does not correspond to the coordinates. The dimming sheet 10 maintains the original transparent state.

In this way, the dimming sheet 10 in a partial area can follow the touch track to present an atomized state. In order to better indicate that the dimming sheet 10 corresponding to the touch track is in an atomized state, in FIG. 5 (a), the touch track is indicated by a bold line.

Please refer to FIG. 7. In some embodiments, the touch track includes a closed track. The closed trajectory forms a closed area. The following steps are included after step S12:

S144: Determine that the touch track is the closed track;

S164: Determine the closed area and determine a conductive film block corresponding to the closed area;

S104: Control the application or disconnection of one or more working voltages of the conductive film block corresponding to the closed area to adjust the light transmittance of the corresponding dimming area.

Please continue to refer to FIG. 5 (b). It can be understood that the touch area 162 detects the touch track in real time and determines the coordinates of the touch track. The controller 18 processes the coordinate information and determines whether the trajectory is continuous and closed. When the controller 18 judges that the trajectory can form a closed area, it determines the complex dimming area 122 corresponding to the closed area. Specifically, when the controller 18 controls the conductive film block 14 to apply the operating voltage of the dimming region 122 corresponding to the closed region, the light transmittance of the dimming region 122 becomes large, that is, the dimming sheet 10 is in a transparent state. That is to say, when the user touches and forms a closed trajectory in the touch area 162, the light transmittance of the corresponding dimming area 122 changes, which is expressed as the dimming sheet 10 becomes transparent in the closed area and the closed area The outer corresponding dimming area 122 maintains the original fogging state.

In this way, the dimming sheet 10 can determine the closed area according to the touch track, so that the closed area is in a transparent state.

When the controller 18 controls the conductive film block 14 to turn off the operating voltage of the dimming region 122 corresponding to the closed region, the light transmittance of the dimming region 122 becomes smaller, that is, the dimming sheet 10 is in an atomized state. That is to say, when the user touches and forms a closed trajectory in the touch area 162, the light transmittance of the dimming area 122 at the corresponding position changes. The corresponding dimming sheet 10 outside the area maintains the original transparent state. Fig. 5 (b) shows that the inside of the closed area is fogged and the outside of the closed area is transparent.

In this way, the dimming sheet 10 can determine the closed area according to the touch trajectory, so that the closed area presents a fogged state. FIG. 5 (b) is a schematic view showing that the closed area on the light control sheet 10 is in an atomized state.

When the controller 18 determines that the touch track cannot form a closed area, the dimming sheet 10 may follow the touch track to show a transparent or fogged state.

Referring to FIG. 8, in some embodiments, the touch track includes a direction track. The directional track includes a first direction and a second direction that is perpendicular to the first direction. The directional track includes a first length in a first direction and a second length in a second direction. The first length and the second length form a rectangular area surrounding the trajectory of the direction. The following steps are included after step S12:

S146: Determine that the touch track is the direction track;

S166: determine the rectangular area and determine a conductive film block corresponding to the rectangular area; and

S106: Control the application or disconnection of one or more working voltages of the conductive film block corresponding to the rectangular region to adjust the light transmittance of the corresponding dimming region.

Please continue to refer to FIG. 5 (c). It can be understood that the first direction of the touch area 162 may be the horizontal direction (parallel to the horizontal line) of the light control film 10, or the vertical direction (perpendicular to the horizontal line) of the light control film 10, It can also be a diagonal direction (at an angle of 45 ° to the horizontal line), and the embodiment of the present invention does not limit which direction the first direction is specifically. Correspondingly, when the first direction is the lateral direction of the light control sheet 10, the second direction is the longitudinal direction of the light control sheet 10. The effective length of the touch track in the first direction is called the first length, and the effective length in the second direction is called the second length. The first length and the second length may form a rectangular area surrounding the touch track. As shown in FIG. 5 (c), the trajectory of the direction such as the first length and the second length determines a rectangular area.

Specifically, the touch area 162 detects the touch track in real time, and determines the coordinates of the touch track. The controller 18 processes the coordinate information and determines a first length of the touch track in the first direction and a second length of the touch track in the second direction. The controller 18 determines a rectangular area according to the first length and the second length, and then the controller 18 determines a complex dimming area 122 corresponding to the rectangular area.

When the controller 18 controls the conductive film block 14 to apply the operating voltage of the light adjustment area 122 corresponding to the rectangular area, the light transmittance of the light adjustment area 122 becomes large, that is, the light adjustment sheet 10 is in a transparent state. In other words, when the user touches the touch area 162, the light transmittance of the dimming area 122 corresponding to the rectangular area changes, and the dimming sheet 10 in the rectangular area becomes transparent, while the dimming outside the rectangular area is dimmed. The sheet 10 remains in the original atomized state.

In this way, the dimming sheet 10 can determine the rectangular area according to the touch track, so that the rectangular area is transparent.

When the controller 18 turns off the operating voltage of the dimming region 122 corresponding to the closed region, the light transmittance of the dimming region 122 becomes small, that is, the dimming sheet 10 is in an atomized state. That is to say, when the user touches the touch area 162, the light transmittance of the dimming area 122 corresponding to the rectangular area changes, and the dimming sheet 10 in the rectangular area is in an atomized state, and outside the rectangular area, The dimming sheet 10 remains in the original transparent state. FIG. 5 (c) is a schematic view showing that the rectangular region on the light control sheet 10 is in a fogged state.

In this way, the dimming sheet 10 can determine the rectangular area according to the touch trajectory, so that the rectangular area is in an atomized state.

Please refer to FIG. 9. In some embodiments, the touch track includes a feature track. Feature trajectories include length trajectories and digital trajectories. The length track includes the effective length. The following steps are included after step S12:

S148: Determine that the touch track is the characteristic track;

S168: identify the effective length corresponding to the length track or identify the number corresponding to the digital track;

S108: Control the application or disconnection of the corresponding one or more working voltages of the conductive film block to adjust the light transmittance of the dimming area to the corresponding light transmittance corresponding to the effective length or the number.

Please continue to refer to FIG. 5 (d), it can be understood that the dimming sheet 10 can recognize a specific touch track to control the dimming rate of the dimming sheet 10. The light transmittance of the dimming sheet 10 is related to the working voltage applied to the dimming area 122. The greater the operating voltage applied to the dimming region 122, the greater the light transmittance of the dimming sheet 10. The working voltage of the dimming area 122 is controlled by the controller 18.

Specifically, a characteristic trajectory, such as a digital trajectory, is set. When a number is detected by the touch area 162, the controller 18 adjusts the working voltage of the corresponding conductive film block 14 according to the characteristic trajectory, so that the light transmittance of the light adjusting sheet 10 is adjusted to the light adjusting rate corresponding to the number. For example, if the number “50” is input in the touch area 162 of the light adjustment sheet 10, the controller 18 adjusts the light transmittance of the light adjustment sheet 10 to 50%. The dimmer film 10 can recognize the number of the touch area 162 by related software.

The set feature trajectory can also be a length trajectory. The length track includes the direction and the effective length in that direction. When the touch area 162 detects the length trajectory, the controller 18 adjusts the working voltage of the corresponding conductive film block 14 according to the length trajectory, so that the light transmittance of the light adjustment sheet 10 is adjusted to the light adjustment rate corresponding to the effective length. The direction of the length trajectory may be the lateral direction of the dimming sheet 10 or the longitudinal direction of the dimming sheet 10. Taking the horizontal direction shown in FIG. 5 (d) as an example, the user slides the trajectory of the effective length L1 in the horizontal direction of the dimming sheet 10. The ratio of the effective length to the lateral length L2 of the touch area 162 in the lateral direction is 1: 5, and the controller 18 adjusts the light transmittance of the dimming sheet 10 to 20%. The larger the ratio of the effective length to the length of the touch area 162 in this direction, the larger the light transmittance of the dimming sheet 10 can be adjusted. That is, the greater the distance that the user's finger slides on the touch area 162, the greater the light transmittance of the dimming sheet 10.

In some embodiments, the light modulating sheet 10 may further include a polarizing sheet. The polarizer can be attached between the transparent touch sensor 16 and the conductive film block 14. The polarizing plate can convert natural light without polarization into polarized light, that is, only light in a specific direction passes through the light adjusting plate 10 and absorbs or reflects light in a non-specific direction. In this way, while improving the light transmittance and the viewing angle range of the light adjusting sheet 10, the light adjusting sheet 10 can have an anti-glare function. The following uses a projector as an example to describe the beneficial effects of providing a polarizing plate on the light adjusting plate 10. After the light emitted by the projector from the inner lamp tube passes through the light adjusting sheet 10 provided with a polarizing plate, the light having no polarization direction is polarized, so that the light projected onto the wall is more concentrated. In this way, the projector can increase the brightness of the projection.

In some embodiments, the light modulating film 10 may further include a light filter. Natural light passes through the light-adjusting filter 10 with a filter to filter light of some wavelengths. Take the infrared filter as an example, the infrared filter only allows infrared light to pass through the dimmer 10 and filters out light outside the wavelength range of the infrared light. In this way, the dimmer 10 can be used on an infrared monitoring camera or other infrared devices. .

It can be understood that, in some embodiments, the dimming sheet 10 may further include other devices. Other devices can bring additional functions to the dimmer 10, such as adding a color filter to make the dimmer 10 appear color. Embodiments of the present invention are not limited to adding a device directly to the light adjusting sheet 10 or changing the structure of the light adjusting sheet 10 to add a specific function to the light adjusting sheet 10.
