Assembly of interactive electronic whiteboard is the main touch screen board classroom tool for screw box feet hammer and wrench. When all the tools and raw materials in order to put on the workbench, the order of assembly operation began. Second, shell according to the process CARDS to be put on the workbench, such as assembly fixtures, according to the request of tooling, pay attention to the direction of the shell to the right. And then remove the LCD screen protective film, clean with air-laid paper electrodes, confirm direction, according to the instruction from the process card, right into the electrode shell. Take out your circuit board. If you want to add a backlight, first fixed backlighting on the PCB. Aligned according to the process card, circuit board and frame, shell in the shell, the compaction, shell and circuit board 65 inch smart board with special assembly tools. The careful stent twisted into a 45 degree Angle, don't bite the circuit boards and to cut off the line, make the stents contact with parallel to the PCB. Will be finished assembled, taking it from the workbench, affix protective film, placed on the table. Pay attention to the screen as opposed to a screen, plate and plate relative, lest cause scratch, product assembly is completed by the inspection personnel inspection, unqualified to assembly.
Interactive electronic whiteboard on printed circuit boards assembly is designed to make the corresponding electrode screen one by one, in order to match the electrical performance of the interactive electronic whiteboard. But due to the screen 65 inch touch screen do not contact directly with circuit boards, and conductive adhesive tape, for medium, the screen and circuit board can't direct communication, lead to the corresponding electrode can't communicate, cause dislocation. In the process of assembly electrodes called counterpoint between the screen and circuit board. In the process of assembly, screen and circuit board can be realized through the screen and circuit boards, screens and circuit board can be realized through the screen and circuit board. Shells as intermediate medium, as the corresponding standard screen and shells, is very important on the counterpoint. Counterpoint mainly including edge counterpoint, pinhole counterpoint and intermediate counterpoint.
With the size of the LED LCD screen on the price to touch screen whiteboard about 1 times more expensive than the interactive electronic whiteboard, OLE LCD is more expensive.
In mature technology, because the interactive electronic whiteboard is a traditional display, so in terms of technical mature than OLED LCD, LED, LCD screen, display reaction speed, for example, is not nearly as OLED LCD, LED LCD screen LCD liquid crystal display.
In terms of the Angle of the display, OLED than LED smart board touch screen liquid crystal screen and better interactive electronic whiteboard, embodied in the interactive electronic whiteboard viewing Angle is very small, while the LED LCD screen on the administrative levels and the dynamic performance, the other LED LCD screen depth also is not good enough.
