Touch screen man-machine interface as a whole in a interac... panels for education short period of time

shows a tendency of rapid growth in sales, touch screen man-machine interface is no longer a simple manifestation and control. At present domestic automation industry, some had no human-

machine interface, always also start using human-machine interface, the man-machine interface of user interface to consumers or users can better reflect the equipment and the state of the

process, and the effect of visual and touch, gives customers more intuitive feelings.

Touch screen display screen suddenly maintenance techniques;
Machine fault: power to repair the machine is also a 24 v dc power supply, the input power of the first 24 v is measured with a multimeter and grounding resistance between 2 million, there

is no short circuit, and then open the machine shell, after interac... touch screens education measuring

power fuse, is good. 24 v dc power supply to the machine, the power indicator. Preliminary judgment power supply circuit is normal. Use the flashlight, you can see the picture on the

screen, signal board has showed normal work and the output signal.

Screen display chip is also preliminary judgment as normal. At this point, it is light or high voltage problem. High pressure plate fracture. This is a blackboard. There is no change. Most

of the high pressure plate is damaged, it is a disadvantage, at the same time. For example, the main condenser tube for the 12 v power supply department. High pressure plate by power panel

power supply, the ignition coil primary judgment for normal low voltage power supply circuit. Second, the need to distinguish between high voltage output tube in tube or tube and high pressure

packaging problems, this is the problem that high voltage encapsulation.

Resistance and pressure touch interactive panel

board screens, but their reaction principle is the same, they are in the manufacturing process and the substrate is different. Resistance type pressure screen surface has two conductive

layers, separated by the isolated points in the middle. When human exposure, conductive surface contact, the redistribution of impact current and reaction. Resistive touch screens due to

its own characteristics, especially accurate, are not affected by the work [url=https://www.hsdsmartboard.com/interactive-whiteboard-for-classroom/dual-int... touch screen board environment, the influence of dirt, dust and grease. Any of the items contact will react. Riot, high transparent toughened glass

substrate. It is completely suitable for public use.
