Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 6. These embodiments of the present invention are merely for illustrating the present invention, but the present invention is not limited thereto.

1 is a block diagram of an integrated flat panel display 100 according to an embodiment of the present invention, and conceptually illustrates an internal structure of the integrated flat panel display 100 according to an embodiment of the present invention.

As shown in FIG. 1, the integrated flat panel display device 100 according to an exemplary embodiment of the present invention includes an image reproducing / recording unit 15 (dotted line) and a flat panel display unit 35 (dotted line) connected thereto. It includes. If necessary, the integrated flat panel display 100 may include a voice output unit 60 (dotted line) and an external voice input unit 70 (dotted line) related to voice input / output, and an external signal related to external image input. It may include an input unit 50 (dotted lines). In addition, in some cases, the integrated flat panel display 100 may include various other components. In FIG. 1, the voice output unit 60, the external voice input unit 70, and the external signal input unit 50 may be provided in the integrated flat panel display device 100 in an option form, and are illustrated by dotted lines.

In the integrated flat panel display device 100 according to an embodiment of the present invention, the image reproduction / recording unit 15 and the flat panel display unit 35 are integrated to form a unit. As such, since the image reproducing / recording unit 15 and the flat panel display unit 35 are integrated and provided in the integrated flat panel display device, a separate line can be connected to the flat panel display device to display an image without receiving an image signal from a computer or the like. Can be. That is, in the related art, it is inconvenient to install a device that transmits an image signal and an apparatus that displays an image by receiving the image signal, such as a TV station that transmits an image signal and a TV that receives the image signal. In addition, the separation of the two devices occupied a large occupied space. However, since the present invention does not require a separate line, it is easy to install an integrated flat panel display device in a display such as a store, and there is an advantage that the occupied space is greatly reduced.

The image reproducing / recording unit 15 included in the integrated flat panel display device 100 converts image data that can be input and output from a storage medium and inputs and outputs it as an image signal, and the flat panel display unit 35 processes the image signal to display an image. . Here, the image reproducing / recording unit 15 means an apparatus capable of reproducing or recording an image. This also includes the fact that both image reproduction and image recording are possible. Therefore, the image reproducing / recording unit 15 may reproduce image data recorded on the storage medium provided in the storage medium driving unit 10, and receive image signals from the external signal input unit 50 to store the image data in the storage medium driving unit 10. Can also be recorded on a storage medium provided at the "

The internal structures of the image reproducing / recording unit 15 and the flat panel display unit 35 included in the integrated flat panel display device 100 will be described in more detail as follows.

As shown in FIG. 1, the image reproducing / recording unit 15 includes a storage medium driving unit 10 and a signal processing unit 20. Here, the storage medium driver 10 includes a removable storage medium therein to input and output image data from the above-described storage medium. Two or more storage medium drivers 10 may be included, and various types of storage media may be used by different types of the storage medium drivers 10.

Examples of the storage medium driver 10 include a nonvolatile memory drive, a digital video disk (DVD) player, and the like. In addition, examples of the storage medium included in the storage medium driver 10 include a nonvolatile memory, a portable hard disk, an optical recording medium, and the like. These storage media can reproduce or record image data through the above-described storage medium driving units 10.

In particular, non-volatile memory and portable hard disks have their own AT Attachment Packet Interface (ATAPI) controllers, so they can interface with external devices by themselves, whereas DVD drives can be used as storage media. Since the DVD does not have a separate interface and merely serves as a storage medium, the DVD drive has a controller for an interface. Therefore, nonvolatile memory, portable hard disk, and DVD drive differ in structure from each other.

The signal processor 20 is connected to the storage medium driver 10 and converts image data that can be input and output by the storage medium driver 10 to output an image signal. The signal processing unit 20 is thus mainly responsible for processing image signals. The internal structure of the signal processor 20 will be described later in detail with reference to FIG. 2.

The flat panel display unit 35 connected to the image reproduction / recording unit 15 includes a panel control unit 30 and a flat panel display panel unit 40. In addition, the flat panel display unit 35 may include other components as necessary.

Here, the panel controller 30 connected to the signal processor 20 processes the image signal input and output by the signal processor 20 and outputs the image signal to the flat panel display panel 40. The flat panel display panel 40 connected to the panel controller 30 displays an image according to the image signal output from the panel controller 30. In particular, the integrated flat panel display device 100 according to an embodiment of the present invention preferably displays an image repeatedly. That is, when the integrated flat panel display device 100 is used for advertisement or exhibition, it is possible to draw the attention of consumers by continuously repeating a video or repeating a still image having a specified duration without help of a person.

The flat panel display panel 40 may include a plasma display panel (PDP), a liquid crystal display panel (LCD), an organic light emitting diode (OLED), and the like. Can be. Such a flat panel display panel is merely for illustrating the present invention and the present invention is not limited thereto. As such, when the integrated flat panel display device 10 having the flat panel display panel 40 is installed for advertisement or exhibition, it takes not only a small space, but also has a relatively light and durable product, which is easy to transport.

For example, when the flat panel display panel 40 is a liquid crystal display panel, the panel controller 30 includes a gray voltage generator, a data driver, and a backlight controller. The gray voltage generator generates two gray voltages related to the transmittance of the pixel. Here, one suit has a positive value with respect to the common voltage and the other suit has a negative value with respect to the common voltage. The data driver is connected to the data line of the liquid crystal display panel and selects a gray voltage from the gray voltage generator to apply the gray voltage to the pixel as a data signal. In addition, the backlight control unit drives the liquid crystal display panel by transmitting a driving signal to the backlight unit.

1, the integrated flat panel display 100 may further include an external signal input unit 50 for receiving an image signal from the outside. An external signal input source connected to the external signal input unit 50 may be, for example, a computer. That is, when the integrated flat panel display 100 is connected to a computer through the external signal input unit 50, the integrated flat panel display device 100 may receive an image signal from the computer and display the image signal through the flat panel display panel 40. Here, the computer is for illustrating the image signal source of the external signal input unit 50, but the present invention is not limited thereto.

In particular, since the panel controller 30 may process the image signal, when the image signal is input through the external signal input unit 50, the signal processor 20 and the storage medium driver 10 connected to the panel controller 30 may be used. An image input from the outside via the recording medium can be recorded in the storage medium as image data. Therefore, there is an advantage that can capture (capture) or edit the image input from the outside.

When using such a function, the panel control unit inputs an image signal to the signal processing unit, and the signal processing unit converts it into image data and outputs it to the storage medium driver. The storage medium driver stores the image input through the external signal input unit 50 by storing the data in the storage medium.

The integrated flat panel display device 100 according to an embodiment of the present invention is distinguished from other products, in particular, in voice processing. The audio processing of the integrated flat panel display 100 will be described in detail below.

As shown by a dotted line on the left side of FIG. 1, the integrated flat panel display 100 may further include a voice output unit 60 and an external voice input unit 70 for voice output. The voice output unit 60 includes a voice volume control unit 61 and a voice mixing control unit 63 and includes an amplifier (not shown) for amplifying the voice signal. The voice output unit 60 may be a speaker, for example, and may include an amplifier therein.

The voice output unit 60 connected to the signal processor 20 receives a first voice signal obtained by converting voice data input and output from the storage medium driver 10 from the signal processor 20 and amplifies and outputs the first voice signal. Since the voice output unit 60 includes a variable resistor for adjusting the voice size, the voice output controller 60 may adjust the size of the voice signal to be amplified by adjusting the variable resistor with the voice size adjusting unit 61 provided in the voice output unit 60.

The external voice input unit 70 connected to the voice output unit 60 receives the voice from the outside, converts the voice into a second voice signal, and then amplifies and outputs the voice signal through the voice output unit 60. The external voice input unit 70 may be a microphone. The voice output unit 60 mixes the first voice signal output from the signal processor 20 and the second voice signal output from the external voice input unit 70. The voice output unit 60 includes a voice mixing controller 63 to simultaneously adjust the first voice signal and the second voice signal such that the magnitudes of the above-described first voice signal and the second voice signal are inversely proportional to each other. This will be described in more detail later with reference to FIG. 4.

The audio processing of the integrated flat panel display 100 will be described below with an example. When the presentation is performed by connecting the microphone, which is the external voice input unit 70, to the speaker, which is the voice output unit 60, the presenter may supplement the picture with the image displayed on the integrated flat panel display 100. Accordingly, not only can video and audio be simultaneously provided, but also presentation is possible without other auxiliary devices.

The remaining parts of the integrated flat panel display 100 according to the exemplary embodiment of the present invention shown in FIG. 1 may be easily understood by those skilled in the art, and thus detailed description thereof will be omitted. Hereinafter, the internal structure of the signal processor 20 included in the integrated flat panel display 100 will be described in more detail with reference to FIG. 2.

FIG. 2 is a diagram illustrating an internal structure of the signal processing unit 20 according to an embodiment of the present invention, and schematically illustrates an internal structure of the signal processing unit 20 according to a motion picture experts group (MPEG).

As shown in FIG. 2, the signal processor 20 includes a main processor 201 connected to a vacuum flourescent display (VFD) driver 209. The main processor 201 converts image data input and output from the storage medium driver into an image signal and provides the image signal to the panel controller. In addition, the main processor 201 converts the voice data input and output from the storage medium driver into a voice signal and outputs the voice signal to the voice output unit. The digital voice signal is converted into an analog voice signal through the voice digital / analog converter (DAC) 211, and the voice is three-dimensionally separated through the voice digital theater system (213), so that the sound effect is excellent. There is this.

In addition, the signal processor 20 includes a read only memory (ROM) / flash (213), a synchronous dynamic random access memory (SDRAM) 205, and an erasable programmable ROM (EEPROM) 207, which are memories. Various programs are provided in the main processor 201 to process and control various image data and audio data provided by the storage medium driving unit and the audio output unit.

As described above, the signal processing unit 20 according to an embodiment of the present invention image-codes various moving image data or still image data of the storage medium and displays the same through the flat panel display panel. In addition, audio data embedded in various moving images or still images are converted into audio signals and amplified and output through the audio output unit.

Hereinafter, an integrated flat panel display according to an exemplary embodiment of the present invention will be described with reference to FIGS. 3 and 4 that illustrate the internal components of the integrated flat panel display.

3 is an exploded perspective view of the integrated flat panel display 100 according to an embodiment of the present invention, and specifically illustrates internal components of the integrated flat panel display 100. The structure of the integrated flat panel display 100 shown in FIG. 3 is merely for illustrating the present invention, and the present invention is not limited thereto. Therefore, the integrated flat panel display 100 may be modified into another structure.

The integrated flat panel display 100 shown in FIG. 3 includes a flat panel display panel 40, and the front case 90 and the rear case 92 are coupled to the upper and lower surfaces, respectively, for protection from external shocks. do. In addition, a first speaker 601 and a second speaker 603 are attached to each of the left side and the right side of the front case 90 and the rear case 92 which overlap each other.

The panel controller 30 and the signal processor 20 are connected between the flat panel display panel 40 and the rear case 92 to control internal components of the integrated flat panel display 100. Although not shown in FIG. 3 for convenience, they are connected to and control the components of the integrated flat panel display 100. An external signal input unit 50 is formed at a lower portion of the rear case 92 adjacent to the panel controller 30 so that an external image signal can be input by connecting a computer or the like through a line.

The integrated flat panel display 100 includes storage medium driving units 101 and 103 for driving image data or audio data. Since the inserting portions 1011 and 1013 formed on the storage medium driving portions 101 and 103 are exposed to the outside, it is convenient to insert or remove the various storage media 111 and 113. In FIG. 3, only the nonvolatile memory 111 provided in the first storage medium driver 101 and the optical recording medium 113 provided in the second storage medium driver 103 are illustrated. The present invention is not limited thereto. Therefore, the present invention may be modified in various other forms, such as including two or more storage medium driving units, and a portable hard disk may be used.

The integrated flat panel display 100 may include two or more storage media, wherein the first storage medium is a nonvolatile memory, and the second storage medium is an optical recording medium. Alternatively, the first storage medium may be a portable hard disk, and the second storage medium may be an optical recording medium. In consideration of driving the storage medium, the nonvolatile memory and the portable hard disk have their own interfaces as described above, whereas the optical recording medium does not have the interface, and thus the integrated flat panel display 100 ) Is advantageous. This will be described in more detail later with reference to FIG. 6.

Unlike the volatile memory, the nonvolatile memory 111 stores recorded data even when power is not supplied. For example, the nonvolatile memory 111 may be a flash memory.

The optical recording medium 113 reads data stored in a non-contact manner by using an optical pickup device provided in the second storage medium driving unit 103. As the optical recording medium 113, a mini disk (MD), a compact Examples include compact disks (CDs) and digital video disks (DVDs). The second storage medium driver 103 having the optical recording medium 113 rotates the optical recording medium 113 to read data stored in the optical recording medium 113 through optical pickup.

The removable hard disk drives the hard disk provided therein to read data stored in the hard disk.

4 is a perspective view of a combined flat panel display device 100 according to an embodiment of the present invention, in which all the parts of the flat panel display device 100 shown in FIG. 3 are combined and fixed to the movable support 80. 4 shows a voice mixing control button 631 as an example of the voice mixing control unit, and a volume control button 611 as an example of the voice size adjusting unit. The structures and shapes of the voice mixing control button 631 and the volume control button 611 shown in the enlarged circle of FIG. 4 are merely for illustrating the present invention, but the present invention is not limited thereto.

In addition, the microphone 701, which is an external voice input unit, is connected to the second speaker 603 to amplify and output the external voice through the speakers 601 and 603. Therefore, a supplementary explanation using the integrated flat panel display 100 can be made during the presentation. When the microphone 701 is connected and an external voice is input through the microphone 701, the speakers 601 and 603, which are voice output units, have a first voice signal output from the signal processor and a second voice input from the microphone 701 which is an external voice input unit. Mix signals together.

In this case, the first and second voice signals are simultaneously adjusted such that the magnitudes of the first and second voice signals are inversely proportional to each other through the voice mixing controller. Simultaneous adjustment of such a first voice signal and a second voice signal is possible using a pair of variable resistors. That is, after the first variable resistor of the pair of variable resistors is disposed on the first voice signal side and the second variable resistor is disposed on the second voice signal side, the second variable is inversely proportional to the size control of the first variable resistor. Adjust the resistance to vary. Accordingly, when the size of the first voice signal increases, the size of the second voice signal decreases, and when the size of the second voice signal increases, the size of the first voice signal decreases.

This will be described with reference to the voice mixing control button 631, which is the voice mixing control unit shown in the upper portion of FIG. When the voice mixing control button 631 is in the neutral position as shown in the enlarged circle of FIG. 4, the first and second voice signals are mixed in half and half and are output through the speakers 601 and 603. . When the voice mixing control button 631 is turned counterclockwise, the size of the first voice signal decreases while the size of the second voice signal gradually increases according to the change of the variable resistor, so that the voice input to the microphone 701 is gradually increased. As a result, only the second voice signal is output. On the contrary, when the voice mixing control button 631 is turned clockwise, the size of the first voice signal is gradually increased and the size of the second voice signal is decreased according to the change of the variable resistor, so that the size of the second voice signal is displayed on the flat panel panel 40. The audio suitably harmonized with the image is greatly amplified and output, and the audio input to the microphone 701 is not heard at all.

On the other hand, since the second speaker 603 is provided with a volume control button 611, it is possible to adjust the volume of the voice output through the speakers (601, 603). As shown in the lower portion of the enlarged circle of FIG. 4, when the volume control button 611 is turned fully counterclockwise, the volume can be turned off, and when turned clockwise, the volume is turned on and displayed on the flat panel display panel 40. Sound suitable for the image to be output can be output. The size of the voice can be adjusted by using the variable resistor to adjust the size of the resistor with the volume control button 611.

As shown in FIG. 4, the integrated flat panel display 100 is fixedly attached to the movable support 80 and thus easy to move. Therefore, the integrated flat panel display 100 is not only advantageous for exhibition or advertisement, but also for presentation. A simple description of the image displayed on the integrated flat panel display device 100 can also be made by using. Since the remote controller 85 has a stop and replay function, the remote controller 85 can easily control the image displayed on the integrated flat panel display 100.

Although not shown in FIG. 4, a battery box is provided on the rear surface of the integrated flat panel display 100 to supply power to the integrated flat panel display 100 for a predetermined time without a power connection. Therefore, the integrated flat panel display device 100 may be used even when the power connection is not possible. The second storage medium driving unit 103 is located on the right side of the integrated flat panel display 100 and can be easily attached and detached, and the optical recording medium can be easily inserted or removed.

A process of displaying an image by inserting a storage medium such as an optical recording medium into the integrated flat panel display 100 will be described in more detail below with reference to FIGS. 5 and 6.

FIG. 5 is a schematic conceptual diagram of processing data 1110 embedded in a storage medium according to an embodiment of the present invention, and the moving image data and the still image data embedded in the storage medium are recorded for each line. Indicates. The form of such processing data is merely illustrative of the present invention and the present invention is not limited thereto. Thus, the processing data can be modified in other forms.

As shown in Fig. 5, the storage medium contains processing data 1110, which designates the order and time of an image to be displayed on the flat panel display panel. That is, as shown by the arrow, the corresponding file in which images are displayed in order from top to bottom is designated. The signal processing section reads such processing data and then displays the pictures according to the order and time of the pictures specified in the processing data.

Here, the file with the extension mpg means moving image data, and the file with the extension jpg means still image data. In the case of moving picture data such as movie-01.mpg, the execution time is provided for each moving picture, whereas in the case of the still picture data, it is a still picture so that a time for displaying an image must be specified. Therefore, in the case of a file with an extension of jpg, the time at which the image is displayed is specified. Here, the number 500 shown on the right side of the picture-01.jpg file of the third line means that the still picture data is executed for 500 ms and displayed as an image. After 500ms, the still picture data of the following picture-02.jpg file is displayed as a picture that lasts for 1000ms.

In this way, the processing data 1110 includes image data and at least one or more of moving picture data and still picture data, which are listed in the output order. Since the still picture duration is specified in the still picture data, the picture is continuously displayed for the specified time. Hereinafter, the overall driving process of the integrated flat panel display will be described in more detail with reference to the driving flowchart of FIG. 6.

6 is a driving flowchart of an integrated flat panel display according to an exemplary embodiment of the present invention, and briefly illustrates a process of driving the integrated flat panel display. This will be described according to the driving sequence of the integrated flat panel display as follows.

First, in step S600, driving of the integrated flat panel display is started. A user using an integrated flat panel display inserts a compact flash memory, a nonvolatile memory, and a DVD, an optical recording medium, into a storage medium driving unit of the integrated flat panel display. Here, the compact flash memory and the DVD are for illustrating the nonvolatile memory and the optical recording medium, respectively, but the present invention is not limited thereto. Therefore, other types of nonvolatile memories and optical recording media may be used. In addition, a portable hard disk may be used instead of the nonvolatile memory.

In step S601, the user turns on the power of the integrated flat panel display to operate the integrated flat panel display. As the power of the integrated flat panel display is turned on, the signal processor checks whether the storage medium is inserted into the integrated flat panel display in step S611. Since the signal processor is connected to the storage medium driver into which the storage medium is inserted, the signal processor can easily determine whether to insert the storage medium by checking the signal output from the storage medium driver.

When the storage medium is not inserted, the signal processor checks whether an external signal transmitted from the computer is input through the external signal input unit in step S651. Here, the computer which is an external signal input source is merely for exemplifying the present invention, and an external signal may be input by connecting a device other than the computer. When an external signal is input, the signal processing unit displays the image data input from the outside in step S653 and ends all processes when the display is completed (S660). Through this process, the user can view an image displayed by a file executed on a computer through a large screen.

If no external signal is input, the signal processing unit returns to step S611 again to confirm whether the storage medium has been inserted into the storage medium driving unit. When the storage medium is not inserted into the storage medium drive unit and there is no external signal input, steps S611 and S651 are repeated. Therefore, the user eventually inserts the storage medium into the storage medium drive unit or connects a computer to the external medium. In order to use an integrated flat panel display device, a signal must be input. Otherwise, the user must turn off the integrated flat panel display.

When the storage medium is inserted, the signal processing unit determines in step S621 whether the DVD is inserted into the storage medium driving unit. Hereinafter, a case where both a compact flash memory and a DVD are inserted as a storage medium as an operation process of the integrated flat panel display device will be described.

When the DVD is inserted into the storage medium drive unit as a storage medium, the flow advances to step S631. The signal processing unit first receives the image data from the storage medium driving unit including the DVD so that the flat panel display panel displays the image. The reason for displaying the DVD in preference to the compact flash memory is that the compact flash memory is inserted into the integrated flat panel display in a nearly default form, and the DVD is generally used in a special case. If it is inserted, it is reasonable to use the DVD first.

This is also due to the structural difference between the compact flash memory and the DVD as described above with reference to FIG. The compact flash memory has its own interface interface ATAPI controller. Therefore, since the compact flash memory drive into which the compact flash memory is inserted does not need an interface unit, the integrated flat panel display does not recognize that the compact flash memory drive is connected when the compact flash memory is not inserted. On the other hand, in the case of a DVD, the interface unit is provided in the DVD drive, and the integrated flat panel display recognizes that the DVD drive is always connected.

Therefore, when both the compact flash memory and the DVD are inserted and used in each storage medium driving unit, the signal processing unit must first check whether the DVD is inserted. If the compact flash memory is not inserted, the compact flash memory drive itself is not checked, so the signal processing unit does not need to check whether the compact flash memory is inserted. On the other hand, since the DVD needs to check the insertion state, it is preferable to program the signal processor to check the DVD drive first.

As described above, if it is determined that the DVD as the storage medium is inserted into the storage medium driver, the signal processor reads the title of the DVD in step S631. Even when only the DVD is inserted into the storage medium drive unit, the DVD is driven in the same manner as described later. The signal processing unit reads processing data embedded in the DVD in step S633. Next, in step S635, the signal processing unit outputs an image signal in accordance with the order and time of the image specified in the processing data, and processes it to display the image on the flat panel display. Accordingly, the user can see the image displayed on the integrated flat panel display. The user can not only listen to the sound of the DVD drive through the speaker, which is the voice output unit, but also amplify his or her own voice by connecting the microphone directly to the speaker during the presentation so that others can listen.

If the user takes out the DVD inserted into the integrated flat panel display on which the image is displayed from the storage medium driving unit (S637), the signal processing unit automatically receives the image data from the storage medium driving unit including the compact flash memory and receives the image. Will be displayed. Therefore, when the DVD is taken out of the storage medium drive unit, the compact flash memory is automatically driven to display an image thereof. Accordingly, the user can view the image continuously without interrupting the image.

If the user continues to watch the DVD without removing it from the storage medium drive unit, the image display according to the DVD is terminated, and it is determined in step S639 whether the signal processing unit repeatedly displays the image. In other words, since whether or not the image is repeatedly displayed by the user has already been set to a preset value in the integrated flat panel display, the signal processor decides whether or not to repeatedly display the image. Accordingly, the signal processing unit continuously displays the image repeatedly or stops displaying the image in step S640.

On the other hand, in step S621, when the DVD is not inserted into the storage medium drive unit, the signal processor reads the title of the compact flash memory in step S641. Even when only the compact flash memory is inserted into the storage medium driving unit, the compact flash memory is driven in the same manner as described later to display an image. In step S643, the signal processing unit reads the processing data of the compact flash memory and outputs an image signal in accordance with the order and time of the image specified here. The image signal is processed so that the signal processor displays an image on the flat panel display in step S645 in accordance with the processing data. When all the moving picture data and the still picture data included in the compact flash memory are driven to end the image display, it is determined in step S647 whether or not the signal processing unit repeatedly displays the image. In other words, since whether or not the image is repeatedly displayed by the user has already been set to a preset value in the integrated flat panel display, the signal processor decides whether or not to repeatedly display the image. Accordingly, the signal processing unit continuously displays the image repeatedly or stops displaying the image in step S640.

As described above, the integrated flat panel display device according to the present invention is not only suitable for advertisement or exhibition, but also displays images independently without connection of an external device since the image reproduction / recording unit and the flat panel display unit are integrated into one unit. There is an advantage to this.

In addition, a high-resolution screen can be realized through the flat panel display panel, and the volume is minimized to reduce the occupied area, thereby greatly reducing the power consumption.
