In general, an electronic display board configures a screen with a combination of the three primary colors of red, green, and blue by adjusting the luminance of each pixel, and uses a light emitting body such as a light emitting diode, a fluorescent lamp, or a discharge light as a display element. Recently, LCDs are also used.

These electronic signboards are installed outdoors and play a role in providing necessary information or advertisements to various people through various graphics or videos. Existing electric signboards have implemented the above by converting analog video signals into digital video signals. That is, the signal for conventional television broadcasting was an analog video signal. In the case of Korea, the NTSC method and other regions are made of analog video signals such as PAL/SECAM. In addition, the video signal output from the video equipment was also an analog video signal.

Therefore, the existing electronic display board had to be converted into a digital video signal to express this analog video signal. In addition, the present inventor has also registered a technique for converting to a sequential scanning method using a double speed converter in order to improve the rough screen and resolution of interlaced scanning due to the NTSC method as Patent Registration No. 252619.

However, in the future, digital imaging systems will be the main focus. Reflecting this, in recent years, digital imaging systems such as high-definition HDTV and SDTV have been widely implemented. Therefore, it is urgently required to accommodate the recent high-definition digital video signal and to have a high-definition screen of the electronic display board.

That is, the GPS module 133 is used to transmit the current location of the electronic display board 100 moving as GPS location information to the electronic display board management server 200 when necessary, since the electronic display board 100 is a mobile electronic display board.

The camera modules 134 and 135 function to visually check the operating state of the LED 111 of the electronic display board 100 and poor connection of electrical components inside the electronic display board 100 . That is, the camera module includes the first camera module 134 and the second camera module 135, and the first camera module 134 is installed inside the electronic signboard 100 to capture an internal image of the electronic signboard 100 in operation. Acquire Accordingly, since the first camera module 134 can obtain a more detailed internal image of the electronic display board 100 if the pan-tilt driving is possible, in this embodiment, the first camera module 134 is a pan-tilt method. At the same time, it is a network camera module that can be operated and controlled through the administrator of the electronic signboard management server 200 while transmitting and receiving data based on TCP/IP with the electronic signboard management server 200 by having an IP address. In addition, the second camera module 135 is installed outside the electronic display board 100 and acquires an image of the operating state of the LEDs 111 of the electronic display board 100 in operation, and acquired through the second camera module 135 in this way. Image information about the operating state of the LED of the electronic display board 100 is transmitted to the electronic display board management server 200 through the communication module 136 and the mobile communication network.

Also, as shown in FIG. 3 , the housing 150 of the display board 100 may include a region formed of a transparent material for smooth image information acquisition of the first camera module 134 . That is, since clearer image information can be obtained through the first camera module 134 only when the inside of the electronic signboard 100 is bright, at least a portion of the housing 150 of the electronic signboard 100 is formed of a transparent material. The inside of the electronic display board 100 can maintain a predetermined brightness.

As described above, the electronic display board management server 200 receives monitoring data transmitted through the communication module 136 of the monitoring board 130 through a communication network. The electronic signboard management server 200 includes a communication unit 210, a database unit 120, a signal determination unit 130, a control unit 140, a display unit 150, and the like.

The communication unit 210 functions to transmit and receive various data and signals with the communication module 136 of the monitoring board 130, that is, the temperature sensor 131, humidity sensor 132, and GPS of the monitoring board 130. Data detected and acquired through the module 133 and the camera modules 134 and 135 are transmitted through the communication module 136 of the monitoring board 130 and received through the communication unit 210 of the electronic signboard management server 200. In addition, the control signal generated by the controller 240 of the electronic signboard management server 200 is transmitted to the communication module 136 of the monitoring board 130 through the communication unit 210 . At this time, the communication module 136 of the monitoring board 130 and the main control board 120 are electrically connected, and signals and data for controlling the operation of the electronic display board 100 transmitted from the electronic display board management server 200 are transmitted.

In other words, the monitoring board for detecting the operating environment and operating state of the signboard is installed in conjunction with the uninterruptible power supply to maintain the monitoring function of the operating environment of the signboard at all times even if the main power for the signboard is cut off. Electronic sign board management through a remote electronic sign board management server can be maintained continuously and stably.

The video transmission equipment 3 includes all devices that transmit analog video signals, digital video signals, and high-definition digital video signals. It may be a player, VTR, DVD, camera, copier, scanner, cable TV, and the like. In this way, the video transmission equipment 3 includes both wired and wireless devices that transmit the above-mentioned signals.

The PC graphic 5 is a video signal edited and processed by a PC (personal computer), and this video signal is screen data such as images and graphic characters by the PC. This PC graphic 5 is edited to display general text and/or graphic text-related news and/or advertisements, moving pictures, and the like. The video signals of this PC graphics 5 include both analog and digital video signals.

The video input unit 1 receives video signals from the video transmission equipment 3 and the PC graphics 5. As can be seen from the above, this video signal is a video signal with a different signal system. The video input unit 1 edits the video signal to be displayed on the display panel 30 described below. That is, the image input unit 1 processes the image data of the sequential scanning method to be displayed on the display panel 30 by dividing and editing the obtained analog and digital related image signals.

To this end, the video input unit 1 includes a video input/double speed converter circuit unit 7 and a PC graphic circuit unit 9. Among them, the video input/double speed converter circuit unit 7 separately processes analog video signals, digital video signals, or high-definition digital video signals received from the video transmission equipment 3 and displays them on the display panel 30 using a sequential scanning method. It plays a role in converting into a digital signal of Further, the PC graphics circuit unit 9 serves to classify and process video signals received from the PC graphics 5 and convert them into digital signals to be displayed on the display panel 30 .

This video data processed by the video input unit 1 is transmitted to the main video signal control unit 11. The main image signal control unit 11 serves to perform scaling processing so that the received image data is displayed in conformity with various conditions of the display panel 30 . The processed image data is output to the input/output buffer 13 through primary gamma correction.

Furthermore, as will be described below, the main video signal control unit 11 is composed of a two-channel image processor and serves to control a full screen to be displayed on the display panel 30 . That is, the video signal received and processed by the video input unit 1 is a full screen video signal. However, it was true that the display panel 30 displayed a screen with a part cut off because the existing electronic display board had insufficient processing of this full-screen video signal. Therefore, the main video signal control unit 11 scales the video signal and video data from the related video input unit 1 to meet various conditions of the display panel 30, that is, enlarges/reduces the video data to the display panel 30. to be displayed in full screen.

In addition, a control computer 15 is connected to the main video signal control unit 11. This control computer 15 determines whether to display the video signal from the video transmission device 3 on the display board 30 or the PC graphic 5, for example, the screen, advertisement, or text of game content to the display board 30. It plays a role in determining whether to express. As described above, the control computer 15 sets a gamma correction value for the image data processed by the main video signal control unit 11 and processes/controls the display schedule for the display panel 30, the luminance for day and night, and the like. play a role

In addition, a monitor unit 17 is connected to the main video signal control unit 11 . The monitor unit 17 serves to monitor whether the image data processed by the main video signal control unit 11 is processed and output in accordance with various conditions of the display panel 30 . To this end, the main video signal control unit 11 outputs the same video data as the processed video data output to the buffer 13 to the monitor unit 17, and the monitor unit 17 receives the video data and displays the video data. monitor the data. Therefore, the user can conveniently monitor the display status of the display panel 30 installed in a remote place through the monitor unit 17, and based on this, correction/editing of image data with errors can be easily processed.

When video signals are sampled and converted into digital signals for processing, all signals must be controlled by the timing signal synchronized with the video synchronization signal to achieve stable screen display without screen distortion or flicker. These are the signal generator 19 and the timing generator 21.

The signal generator 19 and the timing generator 21 are connected to the double frame memory 23 and the secondary gamma conversion/line driver 25 to perform the above purpose of the screen image displayed on the display panel 30.

The double frame memory 23 serves to store one frame of image data to be displayed on the display panel 30, that is, screen data, and to read and display it when displayed on the display panel 30. In general, the screen image displayed on the display panel 30 is displayed at a very high speed of 60 frames or more, and since it is a large amount of data, rattling occurs when read/write by one memory, and more than 60 frames are displayed. It was true that it was difficult to express. Accordingly, the double frame memory 23 implements a sequential scanning method of image data output from the buffer 13 by performing read and write alternately by doubling the frame memory.

In addition, since general video equipment is designed to suit the light emitting characteristics of TV cathode ray tubes, when a screen image from the video equipment is displayed on the display panel 30 as it is, its color and luminance may vary. However, this is solved in the secondary gamma conversion/line driver 25 sequentially connected to the double frame memory 23 in the present invention. That is, the secondary gamma conversion/line driver 25 corrects a signal suitable for the characteristics of a display element, such as a light emitting diode, and the following display controller 27 connected thereto controls the display panel 30 installed in a remote location. Since it is located in the display unit and is separated by a considerable distance, it serves to amplify the signal and reduce the loss when transmitted to the display controller 27.

In addition, the display panel 30, which is generally installed outdoors, has a large matrix structure using LED modules as display elements (see FIG. 2). Therefore, since it is impossible to serially transmit image data of the entire screen to the display panel 30 , for this reason, the image data must be divided into blocks of the display panel 30 and transmitted. This role is performed by the display controller 27 . The display controller 27 serves to re-divide the image data divided into a plurality of pieces on the display panel 30 into individual pieces for displaying a screen on the display elements of the display panel 30 . To this end, the display controller 27 includes a time generator and a field memory.

Reference numeral 29 denotes a light emitting element driving means for the display panel 30 using an LED module as a display element. The electric signboard of the present invention displays the image acquired through the system as described above on the display panel 30 correspondingly. However, in order to achieve the object of the present invention in this system, it is important to process the acquired analog and digital related image signals having different signal systems to be displayed on the display panel 30 . The role of this processing belongs to the video input unit 1. The video signal processed by the video input unit 1 must also be scaled to match the various display panels 30, which is the responsibility of the main video signal control unit 11. In addition, it is important to monitor whether the image data is processed in accordance with the various conditions of the display panel in the main video signal control unit 11, which is the responsibility of the monitor unit 17. Therefore, the electronic display board of the present invention will be a video input unit 1, a main video signal control unit 11, a monitor unit 17, and finally a display panel 30 with an LED module displaying an image as a display element.

Hereinafter, the structure of the video input unit 1, the main video signal control unit 11 and the monitor unit 17 will be described in detail to achieve the object of the present invention. 3 is a block diagram showing the structure of the video input unit and the main video signal control unit in the present invention, and FIG. 4 is a block diagram showing the detailed structure of the main video signal control unit in FIG.

It has been recalled that the video input unit 1 in the present invention includes a video input/double speed converter 7 and a PC graphics circuit unit 9. Among them, the video input/double speed converter 7 is roughly divided into an analog video signal input unit 40, a digital video signal input unit 50, and a high-definition video signal input unit 60.

The analog video signal input unit 40 acquires and processes existing analog video signals for TV broadcasting, that is, NTSC/PAL/SECAM, and includes a first double speed converter 41 and an A/D converter 43. The first double-speed converter 41 processes the analog video signal and outputs a high-quality red (R), green (G), and blue (B) composite video signal of a sequential scanning method. This first double speed converter 41 incorporates a high precision motion picture detection circuit and a double speed processing unit. When 525 lines of scan lines (480 lines of effective scan lines) of the NTSC method are expressed as they are on a large screen of a TV or monitor, the scan lines are visible and play a role in improving problems such as line flicker or line clogging. Therefore, the first double speed converter 41 separates 3-dimensional Y/C, interpolates scan lines, converts them into sequential scan data, and then increases the horizontal resolution to 800 lines for high-definition red (R), green (G), and blue. (B) Composite video signal is output.

In addition, the A/D converter 43 adjusts the level of high-quality red (R), green (G), and blue (B) composite video signals, which are analog signals, through a preamplifier, and converts them to a high-performance PLL (Phase Locked Loop) circuit. It serves to convert each of the red, green, and blue image signals into 8 to 10-bit digital image signals for display on the display panel 30 by the clock generated by the clock.

In addition, the digital video signal input unit 50 acquires and processes SDTV signals, which are digital broadcasting, and includes a first equalizer/reclocker 51, and a serial/parallel converter (Deserializer) ( 53) and a second double speed converter (Deinterlacer) 55.

The first equalizer/reclocker 50 automatically adjusts the gain of the acquired digital video signal, that is, 259M serial digital data, and restores the high-performance clock and data. The serial-to-parallel converter 53 serves to convert and generate the serial signal from the first equalizer/reclocker 50 into 10-bit parallel digital video data and a synchronous clock. Since the video signal primarily converted to be suitable for the display panel 30 is a signal of the interlaced scanning method of 525 scan lines, the second double speed converter 55 converts the video signal from the serial-parallel converter 53 into high-definition sequential scanning. It plays a role in transforming the way.

In addition, the high-definition digital video signal input unit 60 obtains and processes an HDTV signal, which is a high-definition digital broadcast, and includes a second equalizer/reclocker 61, and a deformatter 63 and a second equalizer/reclocker 61. It includes a 3x converter (Deinterlacer) 65.

The second equalizer/reclocker 61 performs adaptive cable equalization on the acquired high-definition digital video signal, that is, the SMPTE 292M component serial digital video signal, restores the clock and data, and converts the serial data in parallel. It plays a role in generating bit data and synchronization clock.

The deformatter 63 serves to convert 20-bit HDTV parallel data from the second equalizer/reclocker 61 into 10-bit luma and 10-bit chroma.

As described above, according to an embodiment of the present invention, in the integrated board control system, the scaler, the subtitler, and the controller are implemented as one board without the controller, the scaler, and the text subtitler, respectively, and the scaler and the subtitler perform Regarding the operation, by implementing the scaler function and the subtitle function in software and installing them in the one-board controller, there is an effect of reducing the volume and price while enabling multi-functional multi-control more easily.
