It includes at least one second sensor that senses polarity, and the first sensor and the second sensor may be disposed on the back of the transparent panel 410.

Here, the plurality of magnets are arranged in a matrix form on the light shielding film, and the plurality of magnets arranged in the column or transverse direction may be arranged by mixing magnets with a first polarity and magnets with a second polarity.

In addition, the first sensor will be disposed corresponding to the first row among the plurality of magnets if the moving direction of the light shielding film is perpendicular to the transparent panel, and the second sensor will be disposed corresponding to the second row adjacent to the first row. You can.

As an example, the plurality of magnets arranged in the first row include magnets having the first polarity and magnets having the second polarity mixed and arranged in the first arrangement order, and the plurality of magnets arranged in the second row have the first polarity. The magnets having and the magnets having the second polarity may be mixed and arranged in a second arrangement order different from the first arrangement order of the first row.

In addition, the first sensor is disposed corresponding to the first row among the plurality of magnets when the moving direction of the light shielding film is horizontal to the transparent panel, and the second sensor is disposed corresponding to the second row adjacent to the first row. can be placed.

Additionally, the driving unit may include a step motor or a DC motor, but this is only an example and is not limited thereto.

As another example, the electronic light blocking unit may include a light blocking plate in which a plurality of light blocking pixels are arranged in a matrix, and a driving unit that drives the light blocking pixels of the light blocking plate to move the light blocking area of the light blocking plate to the moving target position.

Here, the light blocking plate may include a transparent upper plate on which the first electrode is arranged, a transparent lower plate on which the second electrode is arranged and at a certain distance from the transparent upper plate, and a light blocking material filled in the light blocking pixel area between the transparent upper plate and the transparent lower plate. there is.

At this time, the light blocking plate may transmit or block light by changing the arrangement of the light blocking material in each light blocking pixel area depending on the voltage applied to the first electrode and the second electrode.

In addition, the light blocking material is at least one of mixed liquid crystals in which a plurality of liquid crystals with different arrangement characteristics are mixed and mixed pigments in which two or three pigments with different light absorption wavelength bands are mixed to block the wavelength band of visible light. It can be done as one.

As an example, the mixed liquid crystal may be a mixture of polymer dispersed nematic liquid crystals (PDNLC), negative nematic liquid crystal, and cholesteric liquid crystal at a certain ratio.

Additionally, the mixed pigment may be a pigment containing azo pigment, quinacridone, and perylene, but this is only an example and is not limited thereto.

Meanwhile, the processor 430 checks whether the screen mode of the transparent panel 410 is a light-blocking required mode, and if it is a light-blocking required mode, determines the moving target position of the light-blocking area, and moves the light-blocking area to the moving target position. 420 is controlled, and the image output of the transparent panel 410 is controlled according to the moving distance of the light blocking area, and when the light blocking area reaches the moving target position, the image output control of the transparent panel 410 can be terminated. .

Here, when checking whether the mode requires light blocking, the processor 430 checks the current screen mode of the transparent panel 410 if the transparent panel 410 is in the on state, and based on the mode information of the current screen mode, the transparent panel ( 410), it is possible to check whether shading is necessary.

For example, the processor 430 determines that shading of the transparent panel 410 is unnecessary if the current screen mode is transparent mode, and determines that shading of the entire area of the transparent panel 410 is necessary if the current screen mode is opaque mode. If the current screen mode is a partially transparent mode, it is determined that some areas of the transparent panel 410 require shading, and if the current screen mode is a full rollable mode, the shading area of the transparent panel 410 is determined to cover the entire screen. It is determined that shading is required to gradually increase until the current screen mode is partially rollable, and the shading area of the transparent panel 410 can be determined to need shading to gradually increase up to a specific area of the screen.

Next, when checking whether the mode requires light blocking, the processor 430 checks the screen mode corresponding to the specific function when a user input requesting a specific function is received, and based on the mode information of the screen mode corresponding to the specific function It is possible to check whether the transparent panel 410 needs to be shielded from light.

Then, when checking whether the light blocking required mode is present, the processor 430 checks the current screen mode, first determines whether the transparent panel 410 needs to be light blocked based on the mode information of the current screen mode, and makes the first decision. Later, when a user input requesting a specific function is received, the screen mode corresponding to the specific function is checked, and whether the transparent panel 410 needs to be shaded is secondarily determined based on the mode information of the screen mode corresponding to the specific function. If the screen mode corresponding to a specific function is different from the current screen mode, the final decision on whether the transparent panel 410 needs to be shaded can be changed from the first decision to the second decision.

Here, the processor 430 first determines that shading of the transparent panel 410 is unnecessary if the current screen mode is a transparent mode, and if the screen mode corresponding to a specific function is a partially transparent mode, a partial area of the transparent panel 410 is blocked. A second decision is made that shading is necessary, and if the screen mode corresponding to a specific function is different from the current screen mode, the first decision can be changed to a second decision to finally determine that some areas of the transparent panel 410 need shading. .

Next, when determining the position of the moving target in the light blocking area, the processor 430 may obtain light blocking information corresponding to the light blocking required mode and determine the moving target position in the light blocking area based on the obtained light blocking information.

Here, the processor 430 has an internal memory or an external memory that stores a shading data table in which the shading area size, target pixel line position, shading area movement speed value, and shading area movement distance value of the transparent panel 410 are set for each shading requirement mode. Light shading information can be obtained from the server.

As an example, the light blocking data table includes a first light blocking required mode in which the light blocking area size of the transparent panel 410 is set to the entire screen area, and a second light blocking need mode in which the light blocking area size of the transparent panel 410 is set to a partial screen area. Mode, a third light-shielding required mode set to a first rollable effect in which the size of the light-shielding area of the transparent panel 410 gradually increases to the entire screen area, a third light-shielding required mode in which the size of the light-shielding area of the transparent panel 410 gradually increases to a portion of the screen It may include a fourth light-shading need mode set to a second rollable effect.

When determining the moving target position of the light blocking area, the processor 430 uses a pixel line located at one end of the transparent panel 410 if the light blocking area size of the transparent panel 410 is set to the entire screen in a light blocking required mode. The moving target position of the light blocking area is determined, and if the light blocking area size of the transparent panel 410 is set to a partial area of the screen, the pixel line located in a specific area of the transparent panel 410 is set to the moving target position of the light blocking area. can be decided.

For example, when the processor 430 is in a light-shielding required mode in which the size of the light-shielding area of the transparent panel 410 is set to the entire screen area, the direction in which the light-shielding area of the light-shielding part 420 moves is from the bottom of the transparent panel 410. If the first direction is upward movement, the first horizontal pixel line located at the upper end of the transparent panel 410 is determined as the movement target position of the light blocking area, and the movement direction of the light blocking area of the light blocking area 420 is determined by the transparent panel 410. ), in the second direction moving from the top to the bottom, the last horizontal pixel line located at the lower end of the transparent panel 410 is determined as the movement target position of the light blocking area, and the movement direction of the light blocking area of the light blocking area 420 is determined. In the third direction moving from the right to the left of the transparent panel 410, the first vertical pixel line located at the left end of the transparent panel 410 is determined as the moving target position of the light blocking area, and the light blocking of the light blocking area 420 is determined. If the area movement direction is the fourth direction moving from the left to the right of the transparent panel 410, the last vertical pixel line located at the right end of the transparent panel 410 can be determined as the movement target position of the light blocking area.

In addition, when the processor 430 is in a light-blocking required mode in which the size of the light-blocking area of the transparent panel 410 is set to a partial area of the screen, the direction in which the light-blocking area of the light-blocking part 420 moves is from the bottom to the top of the transparent panel 410. In the first direction of movement, a horizontal pixel line located in a specific area from the lower end of the transparent panel 410 to the upper direction is determined as the movement target position of the light blocking area, and the movement direction of the light blocking area of the light blocking part 420 is transparent. In the second direction moving from the top to the bottom of the panel 410, a horizontal pixel line located in a specific area from the top end of the transparent panel 410 to the bottom is determined as the moving target position of the light blocking area, and the light blocking area 420 ), if the direction of movement of the light blocking area is the third direction moving from the right to the left of the transparent panel 410, the vertical pixel line located in a specific area from the right end of the transparent panel 410 to the left is the moving target position of the light blocking area. If it is determined that the direction of movement of the light blocking area of the light blocking portion 420 is the fourth direction moving from the left to the right of the transparent panel 410, the vertical pixel located in a specific area from the left end to the right of the transparent panel 410 The line can be determined as the moving target position in the light blocking area.

Next, the processor 430 may have different methods for controlling the mechanical light-shielding unit and the method for controlling the electronic light-shielding unit.

The method of controlling the mechanical light blocking part is explained as follows.

When controlling the mechanical light-shielding unit, the processor 430 controls the driving unit to move the light-shielding film to the moving target position, and when the light-shielding film moves, it can calculate the moving distance of the light-shielding film.

Here, when calculating the moving distance of the light shielding film, the processor 430 calculates the moving distance based on the driving signal of the driver, determines whether the moving distance is offset based on the sensing signal of the sensor, and determines the offset of the moving distance. In this case, the driver counts the number of offsets, checks whether the total number of counted offsets is more than the preset maximum number, and, if the total number of offsets is less than the preset maximum number, corrects the moving distance of the light shield based on the total number of offsets. can be controlled.

Additionally, when calculating the movement distance of the light shielding film, the processor 430 may recognize a movement error of the light shielding film if the total number of offsets is greater than a preset reference number.

Here, when the processor 430 recognizes a movement error of the light shielding film, it can control the driving unit to return the light shielding film to its initial state.

Next, when the processor 430 recognizes a movement error of the light blocking film, it can generate an error message corresponding to the movement error of the light blocking film and display it on the transparent panel 410.

Here, if the processor 430 recognizes a movement error of the light shielding film, it may generate an error message including movement error information of the light shielding film and mode change information for switching the screen mode to transparent mode and display it on the transparent panel 410. .

Additionally, when calculating the moving distance, the processor 430 may calculate the moving distance based on the number of motor rotations of the driving unit or the number of pulses of the driving signal.

Here, the processor 430 may recognize the spacing between the magnets as being equal to the one-step movement distance of the light shielding film due to one rotation or one pulse of the motor.

In addition, when determining whether there is an offset in the moving distance, the processor 430 determines it as an offset if the sensing signal from the sensor is not input due to the sensor not recognizing the rotation of the motor, and moves to the next step when the sensing signal from the sensor is input. The motor can rotate.

Additionally, when correcting the moving distance of the light blocking film, the processor 430 may correct the moving distance of the light blocking film by additionally rotating the motor by the total number of offsets if the total number of offsets is less than the preset maximum number.

Next, the method of controlling the electronic light blocking unit is explained as follows.

When controlling the electronic light blocking unit, the processor 430 controls the driving unit so that the light blocking area of the light blocking plate moves to the moving target position, and when the light blocking area moves, it can calculate the moving distance of the light blocking area.

Here, when calculating the moving distance of the light blocking area, the processor 430 may calculate the moving distance of the light blocking area by counting the light blocking pixel lines that block light in the moving direction of the light blocking area.

For example, if the movement direction of the light blocking area of the light blocking plate is the first direction moving from the bottom to the top of the transparent panel 410, the processor 430 counts the horizontal light blocking pixel line that blocks light from the lower end of the light blocking plate to the upper direction. Calculate the moving distance of the light blocking area, and if the moving direction of the light blocking area of the light blocking plate is the second direction moving from the top to the bottom of the transparent panel 410, a horizontal light blocking pixel line that blocks light from the upper end of the light blocking area to the lower direction is formed. The moving distance of the light blocking area is calculated by counting, and if the moving direction of the light blocking area of the light blocking plate is the third direction moving from the right to the left of the transparent panel 410, a vertical light blocking pixel line blocks light from the right end of the light blocking area to the left. The moving distance of the light blocking area is calculated by counting, and if the moving direction of the light blocking area of the light blocking plate is the fourth direction moving from the left to the right of the transparent panel 410, a vertical light blocking pixel blocks light from the left end of the light blocking area to the right. By counting the lines, the moving distance of the shading area can be calculated.

Meanwhile, when controlling the image output of the transparent panel 410, the processor 430 sets the light blocking surface of the transparent panel 410 in accordance with the moving distance and moving speed of the light blocking area of the light blocking portion 420, The transparent panel 410 can be controlled to output a portion of the entire screen of the image to be output on the transparent panel 410 on the light-shielding surface.

For example, if the screen mode of the transparent panel 410 is a single window mode, the processor 430 outputs a portion of the image on the light-shielding surface of the transparent panel 410, and displays the remaining screen mode other than the light-shielding surface. The transparent panel 410 can be controlled to make the light surface transparent.

Here, if the screen mode of the transparent panel 410 is a single window mode, the processor 430 provides data corresponding to a portion of the image screen to the light-shielding surface of the entire area of the transparent panel 410, and provides data corresponding to a portion of the screen other than the light-shielding surface. Black data can be provided to the non-light blocking surface.

As another example, if the screen mode of the transparent panel 410 is a multi window mode, the processor 430 outputs a partial screen of the first image on the light blocking surface of the transparent panel 410, and displays a portion of the screen other than the light blocking surface. The transparent panel 410 can be controlled to output the second image on the non-light blocking surface.

Here, if the screen mode of the transparent panel 410 is a multi-window mode, the processor 430 provides partial screen data of the first image provided to the light-shielding surface among the entire area of the transparent panel 410 and data provided to the non-light-shielding surface. The transparent panel 410 can be controlled to synthesize data of the second image and output a composite image in which data corresponding to a portion of the screen of the first image and data of the second image are synthesized.

And, when the moving distance of the light blocking area of the light blocking unit 420 increases, the processor 430 outputs an image on the light blocking area of the transparent panel 410, which increases correspondingly, and the light blocking area corresponds to the increased moving distance. Update the current location information, check whether the updated current location information is the moving target location, and if the updated current location information is not the moving target location, move the light blocking area until the updated current location information reaches the moving target location. The process of increasing the distance can be repeated.

Here, when setting the light blocking surface of the transparent panel 410, the processor 430 counts the pixel lines of the transparent panel 410 according to the moving distance of the light blocking area of the light blocking part 420, and counts the pixel lines. The area where they are located can be set as the light blocking surface of the transparent panel 410.

Next, when the light blocking surface of the transparent panel 410 is set, the processor 430 may provide data corresponding to a portion of the entire screen of the image to be output to pixel lines located within the set light blocking surface.

In this way, the present disclosure implements a virtual rollable effect using a transparent panel and a light blocking function by moving the light blocking area to the moving target position and controlling the image output of the transparent panel corresponding to the moving distance of the light blocking area. And the display value can be maximized at the lowest price.

In addition, the present disclosure controls the image output of the light blocking area based on the moving distance of the light blocking film, thereby changing the screen mode to various screen modes such as transparent mode, opaque mode, partially transparent mode, fully rollable mode, partially rollable mode, etc. This can increase the value of transparent display devices by providing not only various conveniences but also fun and interest to users.

As shown in FIG. 6, the light blocking unit 420 of the present disclosure may include a mechanical light blocking unit.

Here, the light blocking portion 420 is located on the rear side of the transparent panel 410 and may be arranged at a certain distance d apart.

The light blocking unit 420 may move in the up and down direction or in the left and right direction of the transparent panel 410 according to a control signal from the processor 430.

The light blocking unit 420 may include a light blocking film that blocks the rear surface of the transparent panel 410, a driving unit that moves the light blocking film to the moving target position, and a sensor that senses the moving distance of the light blocking film.

Here, the light shielding film includes a plurality of magnets disposed at regular intervals on the front surface facing the rear of the transparent panel 410, and the sensor includes at least one first sensor that senses the first polarity of the magnet, and the second sensor of the magnet. It includes at least one second sensor that senses polarity, and the first sensor and the second sensor may be disposed on the back of the transparent panel 410.

The processor 430 controls the driving unit to move the light blocking film to the moving target position, and can calculate the moving distance of the light blocking film when the light blocking film moves.

Next, the processor 430 sets the light blocking surface of the transparent panel 410 according to the moving distance and moving speed of the light blocking area of the light blocking part 420, and sets the light blocking surface of the transparent panel 410 among the entire screen of the image to be output on the transparent panel 410. The transparent panel 410 can be controlled to output part of the screen on a light-shielding surface.

That is, when the moving distance of the light blocking area of the light blocking unit 420 increases, the processor 430 outputs an image screen to the light blocking area of the transparent panel 410, which increases correspondingly, and the light blocking area corresponds to the increased moving distance. Update the current location information, check whether the updated current location information is the moving target location, and if the updated current location information is not the moving target location, move the light blocking area until the updated current location information reaches the moving target location. The process of increasing the distance can be repeated.

As shown in FIG. 7, the light blocking unit 420 of the present disclosure may include an electronic light blocking unit.

Here, the light blocking portion 420 may be disposed on the rear side of the transparent panel 410.

The light blocking unit 420 may include a light blocking plate in which a plurality of light blocking pixels are arranged in a matrix form, and a driving unit that drives the light blocking pixels of the light blocking plate to move the light blocking area of the light blocking plate to the moving target position.

The processor 430 controls the driver so that the light blocking area of the light blocking plate moves to the moving target position, and when the light blocking area moves, it can calculate the moving distance of the light blocking area.

For example, if the movement direction of the light blocking area of the light blocking plate is the first direction moving from the bottom to the top of the transparent panel 410, the processor 430 counts the horizontal light blocking pixel line that blocks light from the lower end of the light blocking plate to the upper direction. Calculate the moving distance of the light blocking area, and if the moving direction of the light blocking area of the light blocking plate is the second direction moving from the top to the bottom of the transparent panel 410, a horizontal light blocking pixel line that blocks light from the upper end of the light blocking area to the lower direction is formed. The movement distance of the light blocking area is calculated by counting, and if the moving direction of the light blocking area of the light blocking plate is the third direction moving from the right to the left of the transparent panel 410, a vertical light blocking pixel line blocks light from the right end of the light blocking area to the left. The movement distance of the light blocking area is calculated by counting, and if the movement direction of the light blocking area of the light blocking plate is the fourth direction moving from the left to the right of the transparent panel 410, a vertical light blocking pixel blocks light from the left end of the light blocking area to the right. By counting the lines, the moving distance of the shading area can be calculated.

8 to 10 are diagrams for explaining a mechanical light-shielding unit of a display device according to an embodiment of the present disclosure, and FIG. 11 is a diagram for explaining the operation of the mechanical light-shielding unit of a display device according to an embodiment of the present disclosure. This is a flow chart for:

As shown in FIG. 8, the light blocking unit of the present disclosure may include a light blocking film 422 that blocks light from the rear of the transparent panel and a driving unit 424 that moves the light blocking film 422 to the moving target position.

Here, the light blocking film 422 may be made of a material that can be rolled up, but this is only an example and is not limited thereto.

Additionally, the driving unit 424 may include a step motor or a DC motor, but this is only an example and is not limited thereto.

The light shielding film 422 can move by the number of rotations of the motor of the driving unit 424.

In the present disclosure, the moving distance of the light shielding film 422 can be calculated based on the number of rotations of the motor or the motor pulse counter.

However, if the light blocking film 422 does not move smoothly due to foreign matter or a specific object being caught, the moving distance of the light blocking film 422 cannot be accurately calculated using only the number of rotations of the motor or the motor pulse counter, so the transparent panel 410 ) may occur where the image displayed in the image and the moving distance of the light shielding film 422 do not match each other.

Accordingly, the light blocking unit of the present disclosure may further add a sensor and a magnet to correct the position of the moving distance of the light blocking film 422.

As shown in FIGS. 9 and 10, the light blocking unit of the present disclosure includes a light blocking film 422 that blocks the back of the transparent panel, a driving unit 424 that moves the light blocking film 422 to the moving target position, and a light blocking film 422 on the light blocking film 422. It may include a plurality of magnets 428 arranged at regular intervals, and a sensor 426 that senses the moving distance of the light shielding film 422.

Here, the light blocking film 422 may have a plurality of magnets 428 disposed at regular intervals on the front surface facing the back of the transparent panel.

And, the sensor 426 includes at least one first sensor 426a that senses the first polarity of the magnet, and at least one second sensor 426b that senses the second polarity of the magnet, and the first sensor 426b The sensor 426a and the second sensor 426b may be disposed on the rear side of the transparent panel.

In addition, the plurality of magnets 428 are arranged in a matrix form on the light shielding film 422, and the plurality of magnets 428 arranged in the column or transverse direction include a magnet 428a having a first polarity and a magnet 428a having a second polarity. Magnets 428 with (428b) may be mixed and arranged.

It may be placed corresponding to the second row adjacent to the first row.

For example, the plurality of magnets 428 arranged in the first row include magnets 428a having a first polarity and magnets 428b having a second polarity mixed in the first arrangement order, and arranged in the second row. The plurality of magnets 428 may be arranged by mixing magnets 428a with a first polarity and magnets 428b with a second polarity in a second arrangement order that is different from the first arrangement order in the first row.

In addition, the first sensor 426a is disposed in correspondence with the first row of the plurality of magnets 428 when the moving direction of the light shielding film 422 is horizontal to the transparent panel, and the second sensor 426b is, It may be arranged to correspond to the second row adjacent to the first row.

In some cases, the sensor 426 may further include a plurality of third sensors 426c.

In the present disclosure, as the number of sensors 426 increases, the moving distance of the light shielding film 422 can be calculated more precisely and accurately.

As shown in FIG. 11, in the present disclosure, when controlling the mechanical light blocking unit of FIG. 10, the motor, which is the driving unit 424, is controlled to move the light blocking film 422 to the moving target position, and when the light blocking film 422 moves, The moving distance of the light shielding film 422 can be calculated.

Here, in the present disclosure, the moving distance can be calculated based on the number of motor rotations of the driving unit or the number of pulses of the driving signal.

As an example, in the present disclosure, the spacing between the magnets 428 can be recognized as being equal to the one-step movement distance of the light shielding film by one rotation or one pulse of the motor.

Meanwhile, in the present disclosure, the offset of the moving distance of the light shielding film 422 can be corrected as follows.

First, in the present disclosure, the light shielding film 422 is moved by rotating the motor, which is the driving unit 424 (S110).

Next, in the present disclosure, it is possible to check whether the sensor 426 that senses the magnetism of the magnet 428 attached to the light shielding film 422 is sensing (S120).

Next, the present disclosure can determine whether there is a movement distance offset of the light shielding film 422 based on the sensing signal of the sensor 426.

Here, in the present disclosure, upon receiving a sensing signal from the sensor 426, it is determined that there is no offset in the moving distance of the light shielding film 422 and the motor can be rotated in the next step (S160).

In the present disclosure, if a sensing signal is not received from the sensor 426, it is determined that there is an offset in the moving distance of the light shielding film 422, and the number of offsets can be counted (S130).

That is, in the present disclosure, if the sensing signal of the sensor 426 is not input due to non-recognition of the sensor 426 according to the rotation of the motor, it is determined to be an offset, and if the sensing signal of the sensor 426 is input, the motor will rotate to the next step. You can.

Next, the present disclosure can check whether the total number of counted offsets is less than a preset maximum number (S140).

Next, in the present disclosure, if the total number of offsets is less than a preset maximum number, the driver 424 can be controlled to correct the moving distance of the light shielding film based on the total number of offsets.

Here, in the present disclosure, if the total number of offsets is less than a preset maximum number of times, the moving distance of the light blocking film 422 can be corrected by additionally rotating the motor by the total number of offsets.

Additionally, in the present disclosure, if the total number of offsets is greater than or equal to a preset reference number, a movement error of the light shielding film 422 can be recognized (S150).

Here, in the present disclosure, when a movement error of the light blocking film 422 is recognized, the driving unit 424 can be controlled to return the light blocking film 422 to its initial state.

Next, in the present disclosure, if a movement error of the light blocking film 422 is recognized, an error message corresponding to the movement error of the light blocking film 422 can be generated and displayed on the transparent panel.

Here, in the present disclosure, if a movement error of the light blocking film 422 is recognized, an error message including movement error information of the light blocking film 422 and mode switching information for switching the screen mode to transparent mode may be generated and displayed on the transparent panel. there is.

As shown in FIGS. 12 and 13, the light blocking unit of the present disclosure includes a light blocking plate in which a plurality of light blocking pixels are arranged in a matrix form, and a driving unit that drives the light blocking pixels of the light blocking plate to move the light blocking area of the light blocking plate to the moving target position ( 540) may be included.

Here, the light blocking plate includes a transparent upper plate 510 on which the first electrode 512 is arranged, a transparent lower plate 520 on which the second electrode 522 is arranged and spaced at a certain distance from the transparent upper plate 510, and a transparent upper plate 510. ) may include a light-blocking material 530 filled in the light-blocking pixel area between the transparent lower plate 520 and the transparent lower plate 520 .

At this time, the light blocking plate may transmit or block light by changing the arrangement of the light blocking material in each light blocking pixel area according to the voltage applied to the first electrode 512 and the second electrode 522.

In addition, the light blocking material 530 is a mixed liquid crystal in which a plurality of liquid crystals with different arrangement characteristics are mixed, and a mixed pigment in which two or three pigments with different light absorption wavelength bands are mixed to block the wavelength band of visible light. It can be comprised of at least one of the following.

In the present disclosure, when controlling the electronic light blocking unit, the driver 540 is controlled so that the light blocking area of the light blocking plate moves to the moving target position, and when the light blocking area moves, the moving distance of the light blocking area can be calculated.

Here, in the present disclosure, when calculating the moving distance of the light blocking area, the moving distance of the light blocking area can be calculated by counting the light blocking pixel lines that block light in the moving direction of the light blocking area.
