In addition, the power consumption of the RF chip 100, in particular, the power consumption consumed when receiving the RF signal from the image display device significantly increases.

In addition, since the ICs such as the analog switch 110, the DC / DC converter 130, the charger 120, and the like are separated from each other on the PCB, the size of the PCB increases, and thus the circuit configuration. There is also a problem that the space efficiency for the reduction.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

4 is a view for explaining a 3D image implementation system according to a first embodiment of the present invention.

As shown in FIG. 4, the 3D image implementing system according to the first embodiment of the present invention includes an image display device 400 and user glasses 410.

The image display device 400 is a display device capable of realizing a 3D image, and refers to an LED display device including a liquid crystal display (LCD), a plasma display panel (PDP), and an organic light-emitting diode (OLED). When a 3D image is provided from a user device such as a broadcasting station or a camcorder, the image display device 400 processes and displays the 3D image data on the screen, and when the 3D image is displayed on the screen, the user synchronizes the synchronization signal. Transfer to the glasses 410. On the other hand, when a 2D image is input, the input 2D image is converted into a 3D image, and when the converted 3D image is implemented on the screen, a synchronization signal synchronized thereto is transmitted to the user glasses 410. Here, converting a 2D image into a 3D image means that when the 2D image of the input unit frame is a left eye image, the left eye image is shifted by a predetermined amount to generate a right eye image for each unit frame. → Right eye (R1) → Left eye (L2) → Right eye (R2). In this case, the depth information of the right eye image may be obtained by using an object and a background of the left eye image, for example.

In addition, the image display device 400 transmits to the user's glasses 410 using RF signals such as Zigbee, Bluetooth, and Wi-Fi, which are bidirectional communication, as synchronization signals. Of course, as the synchronization signal, an infrared (IR) signal or a packet signal may be transmitted in addition to the RF signal. In addition, a synchronization signal, such as an RF synchronization signal, may be transmitted to the user's glasses 410 whenever the left and right eye images are displayed, but when any left or right eye image is displayed, the synchronization signal is first transmitted and at regular time intervals. The synchronization signal may be transmitted. In this case, additional information for a certain time interval may be transmitted together. Such additional information may also include duty information indicating time information that is actually implemented among the entire time that a unit frame can be implemented.

For example, assuming that the image display apparatus 400 transmits a synchronization signal every 60 frames, additional information about the synchronization signal may be transmitted to the user glasses 410. This may be determined at the time of initial system design of the image display device 400. In other words, when the synchronization signal is transmitted every 60 frames, if the additional information is defined (or set) to use the 2-bit signal "10" between the image display apparatus 400 and the user glasses 410, the user glasses ( 410 may determine that the synchronization signal is provided once every 60 frames from the additional information.

On the other hand, the user glasses 410 may be a shutter glass type 3D glasses alternately turn on and off the left and right eyes according to the synchronization signal transmitted from the image display device 400. In this case, the 3D glasses may be designed to receive an IR signal or an RF signal as a synchronization signal, or may be designed to be compatible. The user glasses 410 may include a driving frame for driving the glasses frame, the lens, and the lens. Here, the lens may include a left eye and a right eye glass, and the left eye and the right eye glass may each include two glasses and a liquid crystal between the glasses. In this case, the liquid crystal is twisted according to the voltages applied to the two glasses, so that the opening and closing operation is performed. For example, in the normally white mode, the image is viewed by turning on when the voltages at both ends are applied at the same level, and the image is not viewed by turning off when different levels are applied. Of course, in normal black mode, the opposite will work. With regard to the drive will continue to be discussed in detail.

FIG. 5 is a block diagram illustrating a structure of the user glasses of FIG. 4, and FIG. 6 is a diagram schematically illustrating a configuration of the driving unit of FIG. 5 on a PCB. 7 is a diagram illustrating a detailed structure of the first driver of FIG. 5, and FIG. 8 is a diagram illustrating a detailed structure of the second driver of FIG. 5.

As illustrated in FIG. 5, the user glasses 410 according to the first embodiment of the present invention are shutter glass type 3D glasses, for example, a first driving unit 500, a second driving unit 510_1, and a storage unit ( 510_2 and some or all of the lens unit 520. Here, the inclusion of some or all includes, for example, the first driving unit 500 and the second driving unit 510_1 are integrated with each other, or the storage unit 510_2 is included in the first driving unit 500 or the second driving unit 510_1. It means that it may be configured, or some components may be omitted, it will be described as including all to facilitate a sufficient understanding of the invention.

According to the exemplary embodiment of the present invention, in the user glasses 410, as shown in FIG. 6, the first driver 500 is configured as a single IC chip, and the second driver 510_1 and the storage 510_2 are a single IC chip. It may be configured in the form of. The first driver 500 is Chip A, and is formed on one side of the PCB as shown in FIG. 6 (a), and the second driver 510_1 and the storage 510_2 are formed on the other side of the PCB as Chip B. Can be. Such a double-sided arrangement may be for improving signal interference or heat generation problems of, for example, Chip A and Chip B, which form an IC chip.

In addition, the first driver 500 and the second driver 510_1 may include, for example, a timing signal line for transmitting the timing signal S _T using the synchronization signal received from the first driver 500, and the first driver 500. And a data signal line for performing bidirectional communication between the second driver 510_1. As the data signal line, time interval information in which the timing signal S _T is transmitted in the synchronization signal received by the first driver 500 may be transmitted, or duty information may be transmitted.

Meanwhile, the first driver 500 and the second driver 510_1 may be configured in various forms. For example, referring to the controllers 720 and 820 with reference to FIGS. 7 and 8, the first case is the case in which only the first driver 500 includes the first controller 720 (hereinafter, configuration example 1). . In this case, the first controller 720 of the first driver 500 includes the second driver 510_1 to control the overall operation of the user glasses 410. The second case is the case where only the second drive unit 510_1 includes the second control unit 820 (hereinafter, configuration example 2). In this case, of course, the second controller 820 of the second driver 510_1 includes the first driver 500 to control the overall operation of the user glasses 410. Third, the first driver 500 and the second driver 510_1 include the first control unit 720 and the second control unit 820, respectively (Configuration Example 3). In this case, when the user glasses 410 are designed to be set to operate as a master and a slave, the user glasses 410 may determine arbitrary information and automatically set the master and slave according to the determination result. For example, if it is determined that the first driver 500 performs an error operation, the second driver 510_1 may operate as a master. 7 and 8 have shown the structural example 3 in that.

In more detail, as illustrated in FIG. 7, the first driver 500 may include some or all of the signal transceiver 700, the first bidirectional communication unit 710, and the first controller 720. In this case, the inclusion of some or all of the above means the case of Configuration Example 2 above. For example, when the first driving unit 500 does not include the first control unit 720, the timing signal and additional information of the received synchronization signal are included. It merely serves to simply transfer to the second drive unit (510_1). In order to help full understanding of the invention, it includes everything.

Here, the signal transmitting and receiving unit 700 may be configured to be separated into a signal transmitting end (Tx) and a signal receiving end (Rx), it is preferable in the embodiment of the present invention includes only the signal receiving end except the signal transmitting end. However, for example, when one user glasses 410 that receives a synchronization signal from the image display device needs to transmit a synchronization signal to other user glasses 410, the signal transmitter may further include a signal transmitter.

The signal transceiver 700 receives a synchronization signal received through the antenna 500a. In this process, for example, when the synchronization signal is provided in the form of a packet, the signal transmission / reception unit 700 may additionally perform a process of decoding the corresponding signal, and further, separate the received synchronization signal or use a synchronization signal to provide a new signal. Various operations such as creating may be additionally performed. Here, the separation of the signal may mean that the synchronization signal is separated into additional information such as a timing signal and duty information.

The first bidirectional communication unit 710 may include a communication module for communicating with the second bidirectional communication unit 810 of the second driver 510_1. For example, the additional information separated by the signal transceiver 700 may be provided under the control of the first controller 720 and provided to the second bidirectional communication unit 810 of the second driver 510_1. Furthermore, in the case of the configuration example 3 above, information for setting a master and a slave may be exchanged between the first driver 500 and the second driver 510_1.

The first control unit 720 performs overall control of the signal transceiver 700, the first bidirectional communication unit 710, and the like in the first driver 500. In this process, for example, when the first control unit 720 determines that an error occurs by additionally determining whether an error occurs in the internal operation or the like in the configuration example 3, or when the first driving unit 500 receives the voltage If the system is determined to be unstable by checking the back, the second driver 510_1 may transfer the role of the master.

As illustrated in FIG. 8, the second driver 510_1 includes a signal input / output unit 800, a second bidirectional communication unit 810, a second control unit 820, a charger 830, a voltage converter 840, and a switching. It may include some or all of the portion 850. Here, the inclusion of some or all means that the second control unit 820 may be configured to be omitted, for example, and includes all of them in order to fully understand the invention. However, in the exemplary embodiment of the present invention, the second driving unit 510_1 may be used to include only the switching unit 850.

The signal input / output unit 800 may be divided into a signal input terminal and a signal output terminal. In this case, a synchronization signal from the first driver 500, more precisely a timing signal, is input to the signal input terminal, and the signal output terminal is, for example, one user glasses 410 for transmitting the synchronization signal to the surrounding user glasses 410. In the case of a system for transmitting, the second driver 510_1 may serve to output a signal to transmit a signal through the antenna 500a of the first driver 500.

The second bidirectional communication unit 810 is not significantly different from the first bidirectional communication unit 710, and the charging unit 830 receives a constant voltage from an external commercial power source and provides a constant voltage to the battery through a process such as rectification and smoothing. It plays a role.

In addition, the voltage converter 840 is a DC / DC converter, for example, receives an analog voltage charged in the charging unit 830 or a battery and converts the voltage into a digital voltage, or further boosts and outputs the voltage converted into a digital form. . This converted voltage is used to turn on / off the left and right eye glasses of the user glasses 410.

The switching unit 850 may include a plurality of switching elements. Such a plurality of switching elements are turned on / off the synchronization signal, more precisely the timing signal, and output the voltage provided from the voltage converter 840 to the user glasses 410. Through this, the left and right eyeglasses of the user glasses 410 are alternately turned on / off.

The storage unit 510_2 may include, for example, an EEPROM (Electrically Erasable Programmable Read-Only Memory) capable of reading and writing. The storage unit 510_2 may store, for example, information (or data) for pairing, ie, compatibility of the user glasses 410 and the image display device 400, or a program implementing the algorithm in the form of an information. It may be executed under the control of the second control unit 820. In addition, in FIG. 5, the storage unit 510_2 is integrated with the second driver 510_1 to form an IC. However, the storage unit 510_2 may be integrated into the first driver 500 to form an IC. It will not be limited.

 As a result of the above configuration, the user glasses 410 can seek miniaturization of the user glasses 410 by configuring the second drive unit 510_1 and the storage unit 510_2 of FIG. 5 in the form of one IC chip, The space efficiency required for circuit configuration within the internal PCB can be increased.

In addition, it will be possible to reduce a lot of manufacturing costs compared to when configuring in the form of a plurality of chips as in the prior art. For example, less labor is required to assemble a single chip rather than to assemble multiple chips, thereby reducing the unit cost.

Furthermore, by distributing the structure of the first driver 500 to the second driver 510_1, power consumption or heat generation of the first driver 500 is reduced, and the number of signal output ports, that is, pins, is reduced according to the simplified structure. This can reduce the manufacturing cost.

In addition, since the first driver 500 and the second driver 510_1 may perform operations of the master and the slave, the system may be stabilized and signal processing may be easy.

Meanwhile, referring to FIGS. 5 to 8 so far, as a preferred embodiment of the present invention, the second driver 510_1 includes a charging unit 830, a voltage converter 840, and a switching unit 850, and stores the same. The case where the part 510_2 is not included has been described in detail. However, embodiments of the present invention will not be limited thereto. For example, when the second driver 510_1 includes only the switching unit 850, at least one functional block of the storage unit 510_2, the charging unit 830, and the voltage converter 840 configured as a function block is integrated. Can be configured in the form of an IC chip. In FIG. 5, the storage 510_2 is separately shown from the second driver 510_1 due to an example of a configuration for facilitating writing of data when the storage 510_2 is used as an EEPROM. .

Hereinafter, the storage unit 510_2 of FIG. 5 is integrated into the second driver 510_1 to form an IC chip Chip B.

As illustrated in FIG. 9, the user glasses 410 according to the embodiment of the present invention may include the first driving unit 900, the second driving unit 910, the lens unit 920, and the peripheral circuit units 930 ˜ 950. Include some or all.

In contrast to the structure of the user glasses 410 of FIG. 9, the structure of the user glasses 410 of FIG. 5 further includes peripheral circuit parts 930 to 950, and includes a first driver 900 and a second driver ( The difference is that 910 includes a plurality of timing signal lines for transmitting the synchronization signal.

For example, when the first driver 900 of Chip A processes a synchronization signal and other algorithms as a master to output a voltage for driving the lens unit 920, the number of output ports required may be at least two. . In this case, the second driver 910 of Chip B performs only a role of a simple passive element to simply amplify the output of the first driver 900 and transfer the same to the lens unit 920. If the second driver 910 of the chip B includes a controller, it may be used as a data signal line by connecting three or more conductors.

In addition, the peripheral circuit units 930 to 950 may include a battery unit 930, a button unit 940 such as a power button, and a state display unit 950 for displaying a power-on state and a state of charge of the battery. Although the peripheral circuit units 930 to 950 may be connected to and interlocked with the first driver 900 and the second driver 910 according to the above configuration examples 1 to 3, in FIG. 9, the peripheral circuit units 930 to 950 may be connected to the second driver 910. It shows interlocking.

In addition, the first driver 900 may generate a plurality of timing signals with respect to the received synchronization signal and provide the same to the second driver 910. In this case, it may be preferable to have a plurality of timing signal lines between the first driver 900 and the second driver 910. However, in the embodiment of the present invention, it is preferable to configure a relatively small line in order to reduce the cost.

Other first and second driving units 900 and 910 except for this point is not significantly different from the first driving unit 500 and the second driving unit 510_1 of FIG. 5 and will not be further described.

Here, one timing signal line is included between the first driver 1000 and the second driver 1010. The first driver 1000 generates one timing signal with respect to the received synchronization signal and transmits the generated timing signal to the second driver 1010.

For example, when the second driver 1010 of Chip B serves as a master, and the first driver 1000 of Chip A transmits a synchronization signal and additional information to the second driver 1010 of Chip B. The number of output ports required is at least one.

Other than the above, the first driving unit 1000, the second driving unit 1010, the lens unit 1020, and the peripheral circuit units 1030 to 1050 may be referred to the first driving unit 900 and the second driving unit with reference to FIG. 9. 910, the lens unit 920, and the peripheral circuit units 930 ˜ 950 are not significantly different from those of the detailed description thereof.

As a result of the above configuration, the user glasses 410 of FIG. 10 is reduced in the number of pins of the first driver 1000 implemented in the form of an IC chip as compared to the user glasses 410 of FIG. Fever) will be reduced.

In contrast to the image display apparatus 400 of FIG. 4, the image display apparatus 1100 may also transmit an infrared (IR) signal capable of one-way communication together with an RF signal capable of bidirectional communication as a synchronization signal. In this case, for example, the user glasses 1110, for example, as shown in FIG. 12, the first driver 1200 processes the RF synchronization signal received through the antenna 1200a, the second driver 1210 The infrared signal receiver 1230 may process the infrared sync signal received. This may of course be possible when the first driver 1200 and the second driver 1210 include the respective controllers as in the configuration example 3 above.

If the first driver 1200 is linked to the infrared signal receiver 1230 in FIG. 12, the second driver 1210 does not include a separate controller, and a synchronization signal provided from the first driver 1200. More precisely, the lens unit 1220 may be driven on / off according to the timing signal.

Other than the above, the first driving unit 1200, the second driving unit 1210, the lens unit 1220, and the peripheral circuit units 1240 to 1260 are related to the first driving unit 900 and the second driving unit with reference to FIG. 9. 910, the lens unit 920, and the peripheral circuit units 930 ˜ 950 are not significantly different from those of the detailed description thereof.

In this case, the controller may include a separate determination unit.

For example, the sync, timing, and other information received from the first driver 1400 of Chip A through the infrared signal receiver 1460 may be converted to sync / data by the second driver 1410 of Chip B so that the chip A may be The transmission may be transmitted back to the first driver 1400. In this case, the first driver 1400 of Chip A may convert the sync / data into an RF signal and transmit the same to the glasses 2 to 4 (1310_2 to 1310_4) for the surrounding users through the signal transmission terminal Tx.

Meanwhile, although not separately shown in the drawing, the user glasses 1 1310_1 may receive a synchronization signal, for example, an RF synchronization signal, transmitted from the image display device 1300 through the signal receiving terminal Rx of the first driver 1400. Afterwards, the controller may transmit the corresponding synchronization signal to the user glasses 2 to 4 (1310_2 to 1310_4) around the user through the signal transmitter Tx.

In addition to the above, the first driver 1400, the second driver 1410, the lens unit 1420, and the peripheral circuit units 1430 to 1450 of FIG. 14 are described with reference to FIG. 9. Since the contents of the two driving units 910, the lens unit 920, and the peripheral circuit units 930 to 950 are not significantly different, the description thereof will be omitted.

FIG. 15 is a diagram illustrating a 3D image realization system according to a fourth embodiment of the present invention, and FIG. 16 is a block diagram illustrating a structure of the user glasses of FIG. 15.

15 and 16, the 3D image implementing system according to the fourth embodiment of the present invention includes an image display device 1500 and user glasses 1510. The eyeglasses 1510 may include some or all of the first driver 1600, the second driver 1610, the lens unit 1620, the synchronization signal requester 1630, and the peripheral circuits 1640 to 1660. Can be.

The user glasses 1510 are synchronized from the adjacent image display device 1520 when the adjacent stereoscopic image display device 1520 is located in close proximity to the target image display device 1500 to receive the synchronization signal. It may tend to receive a signal. This may be attributed to the fact that the user glasses 1510 communicate with the surrounding image display device 1520 by signal strength.

In order to improve the above, in the embodiment of the present invention, for example, the infrared signal is received from the synchronization signal request unit 1630 to receive the synchronization signal from the image display device 1500 that the user glasses 1510 are targeting. The unit 1620 is sent to the image display device 1500 that is directed. The image display device 1500 transmits a synchronization signal to the user's glasses 1510 based on the request. The transmission of the infrared signal may be automatically sent by determining the directing direction or may be sent when the user manipulates the button of the button unit 1650.

Except for the above, the first driving unit 1600, the second driving unit 1610, the lens unit 1620, and the peripheral circuit units 1640 to 1660 are related to the first driving unit 900 and the second driving unit with reference to FIG. 9. 910, the lens unit 920, and the peripheral circuit units 930 ˜ 950 are not significantly different from those of the detailed description thereof.

17 is a diagram illustrating a 3D image implementing method according to an embodiment of the present invention.

For convenience of description, referring to FIG. 17 together with FIGS. 13 and 14, the user glasses 1 1310_1 receive a synchronization signal synchronized with a 3D image displayed on the image display apparatus 1300 from the image display apparatus 1300. (S1700).

In operation S1710, the user glasses 1 1300_1 transmit the received synchronization signal to the surrounding user glasses 2 1300_2. In the process, since the user glasses 1300_1 may determine or analyze whether the received synchronization signal is transmitted or not, the glasses 1 1300_1 will not be particularly limited thereto. In addition, since the signal processing has been sufficiently described with reference to FIGS. 13 and 14, further description thereof will be omitted.

Subsequently, the first glasses 1300_1 for the user use the received synchronization signal to operate the first driver 1400 of FIG. 14, more precisely, to transmit a synchronization signal or a timing signal of the synchronization signal to the second driver 1410. (S1720). Of course, the user glasses 2 1300_2 are also driven by the synchronization signal received from the user glasses 1 1300_1.

Thereafter, the first glasses 1300_2 for the user operate the second driver 1410 by the synchronization signal provided from the first driver 1400 to output voltage to the lens unit 1420 so that the left and right eye glasses of the lens unit 1420 are oriented. By alternately driving on / off (S1730, S1740). The user glasses 2 1300_2 also operate in the same manner.

By the above process, the user glasses 1 1300_1 and the user glasses 2 1300_2 can view the 3D image displayed on the image display device 1300.

18 is a flowchart illustrating a method of driving glasses for a user according to an embodiment of the present invention.

For convenience of description, referring to FIG. 18 together with FIGS. 13 and 14, the user glasses 1 1310_1 receives a synchronization signal from the image display device 1300 (S1300). In this case, the synchronization signal may be an IR signal for performing one-way communication or an RF signal such as Bluetooth for two-way communication.

Subsequently, the user glasses 1 1310_1 transmit the received synchronization signal to the surrounding user glasses 2 to 4 1310_2 to 1310_4 (S1810). In this process, the user glasses 1 1310_1 may transmit the received synchronization signal, but may also generate and transmit a new signal after performing a separate signal processing process, and thus the embodiment of the present invention will not be limited thereto.

Thereafter, the user glasses 1 1310_1 alternately drive the left eye and the right eye glasses on / off based on the received synchronization signal (S1820).

For example, the user glasses 1 1310_1 may switch and drive an externally input voltage by a synchronization signal to output a desired voltage alternately to the left eye and the right eye glass, thereby driving on / off. Since the above operation has been sufficiently described above, further description thereof will be omitted.

19 is a flowchart illustrating a method of driving glasses for a user according to another embodiment of the present invention.

For convenience of description, referring to FIG. 19 together with FIGS. 15 and 16, the user glasses 1510 transmits a request signal for requesting transmission of a synchronization signal to the image display apparatus 1500 as a target (S1900). The request signal may be an infrared signal provided by a light emitting device such as an LED. In addition, the user's glasses 1510 may automatically recognize the oriented image display device 1500 to transmit an infrared signal or transmit an infrared signal when the user operates a separate button. This allows you to perform some kind of pairing operation.

Subsequently, the user glasses 1510 receives a synchronization signal based on the request from the image display device 1500 (S1910).

Thereafter, the user glasses 1510 alternately drive the left eye and the right eye glasses on / off based on the received synchronization signal (S1920).

Through such a process, the user glasses 1510 may watch a 3D image displayed on the image display device 1500.

Until now, except for the case of FIG. 12 through various embodiments, the 3D glasses have been separately described as receiving an infrared signal or an RF signal as a synchronization signal. However, in the embodiment of the present invention is not intended to be particularly limited to them. For example, if the 3D glasses are combined glasses, both the infrared signal and the RF signal may be configured to receive the blocks, and the blocks may be designed to operate as needed. For example, when it is determined that the synchronization signal received from the first driver or the second driver is an infrared signal, the blocks for processing the infrared signal may be operated, and if it is determined that the synchronization signal is the RF signal, the blocks for processing the RF signal may be operated. In this process, the 3D glasses may additionally determine and drive the master and slave operations of the first driver and the second driver. The related part has been described above sufficiently, so further description thereof will be omitted.

While the invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
