HD color display Interactive Whiteobard skd for whiteboard manufacturer is a solution that we only offer the clients four fames owing the PCB which is the core element of the infrared touch board. The board panel that we don’t provide can be purchased in your place by yourselves. The central board can be any board like PVC, aluminum, enamel and so on. We will supply all the accessories, namely corners, screws, flat cables to assist you to finish the assembly.Then, you can assembly the whiteboards in your factory, warehouse, or even office
There is no need for you to worry about the assembly process, because we will provide you the proper training until you can assemble it all by yourself.
a. Circuit features
1) Uniform PCB unit
There are only three kinds of PCBs (receiving PCB, emitting PCB and main control board) in one IWB. The units are the same and they can be exchanged when they are arranged on the IWB.
Adopting the advanced logic coding address for the circuit, every PCB is the same and no jumper.
The basic PCB unit has 64 LEDs, each kind of PCB unit (32, 48, 56) can be cut from this one.
As PCB unit can be cut, we can meet the needs to the different size. And it is convenient for customers to assemble the board. Even the maintenance will become more convenient.
2) Same firmware can fit any size of IWB
To other brand, they can’t change the firmware any more once they embed the program on the main control board. But now the same firmware recognizes the different size.
Manufacturers can set the model No. for different size of board without changing the main board.
3) Calibrate the Signal automatically
Sometimes the position of PCB is changed due to some external factors. For example, transporting, shaking and so on. The board can calibrate the changed signal automatically. After a while, the board still can work normally.
When one terminal is moved, such as the receiving terminal is moved to one side, after it connects with the computer, the boards still can be used.
It also can be used when one terminal is moved parallel. The error is permitted to 5-6cm.
Even though there is one obstacle, it can still work on the other area.
If there is not the function of auto calibration, the precision of the board would be decreased. What’s worse, you can’t use the board. In this way, we can improve the product adaptability to environment.
4) Working log of device
The board can generate AD. txt file which is the working log of device when you connect the board with the PC each time. The working log records the running status of circuit and provides the basic data for daily maintenance.
Through AD value in the AD. text, you can evaluate the situations of PCB circuit. If any abnormal condition, we can analyze the following AD value in order to get the results. It is convenient for maintenance after service.
5) Trapezoidal correction
You have to adjust the projection to the rectangle.
Actually, the precision of the board is not accurate when the projection is trapezoid. The deviation may be 2 cm from mouse to the handwriting if the projection is trapezoid.
To Indesign interactive whiteboard, the deviation is nearly less 2mm from mouse to handwriting even though the projection is trapezoid.
For some users who don’t know how to use the projector, it is very convenient and easy to operate the board.
6) Work under sunlight
The board can be used under sunlight. We tested this for thousands of times.
Working under sunlight, it can enhance its stable ability which let the board work in different environment.
7) Self-diagnosis of PCB
Before finished products, we must test each single PCB board with above tester. It is a device researched by our R&D which can test the single PCB board to make sure each unit to be good quality to delivery.
If there is something wrong with the PCB unit, the tester will generate the error code form. Through the error code form, we can analyze the data and come to a conclusion, then manage to maintain the circui
b. Structural features
1) The position of main board
We build the main board in the PCB unit. It is not the separate PCB board any more. In this way, it is easy to design the corner construction for the board.
We can protect the main board more securely. And we can design the common corners for the board.
2) Ideal structure for the PCB support
Our design team can provide the design scheme for the external structure. Our current PCB circuit scheme has Only two screws Without any screw on the AL frame
We can control the cost of components and save more labor cost, and it is easy to install.
C. Extendibility for the peripheral equipment of IWB.
There are several separate and optional models, such as wireless connection, intelligent pen tray and speaker. You can constitute all these models by yourselves.
