Description

Electronic board

This invention relates to a display device, and more particularly to an electronic signage.

With the advancement of multimedia technology, digital signage can be placed in public places to provide information to people in public places. In order to enable electronic kanbans to effectively convey information to the public, electronic kanbans are usually large in size and often located in high places. In addition, in order to avoid affecting the passage of passers-by, electronic kanbans are often placed in close proximity to pillars and walls.

The circuit board of a conventional electronic signboard is usually locked entirely in the housing of the electronic signage. If maintenance is required, the electronic board must be removed and the board removed. However, due to the large size of the digital signage and the above-mentioned electronic signboard setting principles, it is more difficult to disassemble the electronic signboard, so it will take a long time to repair, which is inconvenient for the user.

The invention provides an electronic kanban comprising a display unit, a first circuit board and a second circuit board. The first circuit board is coupled to the display unit, and controls the display unit to perform display. The second circuit board is pluggably connected to the first circuit board, and executes the operating system to provide the first display signal to the first circuit board, so that the first circuit board controls the display unit to display according to the first display signal.

Based on the above, the embodiment of the present invention is designed to be pluggable by connecting the second circuit board which is more prone to failure, instead of locking the entire circuit board in the electronic board as in the prior art, so that The failed second board is replaced, which in turn significantly reduces the cost of servicing the electronic signage.

The above described features and advantages of the invention will be apparent from the following description.

1 is a schematic diagram of an electronic signage according to an embodiment of the invention. Please refer to FIG. The electronic signage 100 includes a display unit 102, a first circuit board 104, and a second circuit board 106, wherein the first circuit board 104 is connected to the display unit 102, and the second circuit board 106 is pluggably connected to the first circuit board 104.

The first circuit board 102 is configured to control the display unit 102 to display an image frame, and the second circuit board 106 is configured to execute the operating system and provide a display signal to the first circuit board 104 so that the first circuit board 104 can be based on the display signal. The control display unit 102 displays a corresponding image screen.

The first circuit board 104 can be, for example, a circuit board dedicated to controlling the display unit 102 for display, and the second circuit board 106 can be designed as a system board of different functions according to actual application requirements. For example, the second circuit board 106 can be, for example, a system circuit board for a multimedia playback device, or a system circuit board for a point of sale (POS) device, as the electronic signage 100 applies different functions. The system board, the electronic board 100 can be a device corresponding to a system board of different functions, such as a multimedia player or a point-of-sale device, but not limited thereto.

In detail, the second circuit board 106 can be configured as shown in FIG. 2 , and includes a wireless transmission unit 202 , a processing unit 204 , and a storage unit 206 . The processing unit 204 is coupled to the wireless transmission unit 202 and the storage unit 206 .

The storage unit 206 can store the operating system and the display data. The operating system can be different from the function of the second circuit board 106. The operating system can be, for example, an Android operating system or a point-of-sale operating system, but not limited thereto.

The processing unit 204 can execute the operating system in the storage unit 206, and can also receive at least one of the operation instructions from other communication devices and the display data through the wireless transmission unit 202 to perform operations corresponding to the operation instructions, such as setting the electronic signage. Screen parameters or open applications, etc., but not limited to this.

The processing unit 204 can output a display signal to the first circuit board 104 according to the display data, so that the first circuit board 104 controls the display unit 102 to display the image frame according to the display signal. By receiving the operation command and display data from the other communication device through the wireless transmission unit 202, the user can control the electronic signboard 100 from the far end, thereby improving the convenience of use of the electronic signage 100. In some embodiments, the display unit 102 can also be, for example, a touch display panel, and the processing unit 204 can perform a corresponding operation according to a touch operation of the user.

Since the second circuit board 106 is pluggably connected to the first circuit board 104, the second circuit board 106 can be used as a second circuit board 106 by using a circuit board that is more prone to failure (such as a system circuit board, but not limited thereto). Thus, when the second circuit board 106 fails, the failed second circuit board 106 can be directly replaced. The maintenance cost of the electronic signage 100 of the present embodiment can be greatly reduced in a manner that the entire circuit board is locked in the electronic board as compared with the prior art, and the entire circuit board needs to be removed during maintenance.

In addition, the first circuit board 104 can have a signal transmission port 108, and the first circuit board 104 can also be connected to other electronic devices, such as a computer or a video playback device, through the signal transmission port 108 to receive a display signal provided by the computer or the video playback device. And controlling the display unit 102 to perform display according to the display signal from the signal transmission port 108. Thus, when the first circuit board 104 is not connected to the second circuit board 106, the electronic board 100 can also have a basic display function, and can receive display signals from other electronic devices for display.

The signal transmission port 108 can be, for example, a High Definition Multimedia Interface (HDMI) port. However, the signal transmission port 108 can also be, for example, a connection interface of other interfaces, such as a video graphics array ( Video Graphics Array, VGA) port. In addition, the first circuit board 104 is not limited to having only one signal transmission port, and may also have a plurality of signal transmission ports of the same or different transmission interfaces.

FIG. 3 is a schematic diagram of an electronic signage according to another embodiment of the present invention. Please refer to FIG. 3. The electronic kanban 300 of the present embodiment may further include a connector 302 than the electronic kanban 100. The second circuit board 106 is pluggably connected to the first circuit board 104 through the connector 302.

In this embodiment, the connector 302 is implemented by an inter alia Peripheral Component Interconnect Express (PCIE) connector, but not limited thereto. The connector 302 can include a PCIE slot 302-1 and a PCIE plug 302-2. The PCIE slot 302-1 and the PCIE plug 302-2 are respectively disposed on the first circuit board 104 and the second circuit board 106 by combining PCIE. The slot 302-1 and the PCIE plug 302-2 may connect the first circuit board 104 and the second circuit board 106 to each other.
