IBM 12 30CM Pos Monitor Elo-Infrarot Touchscreen RS232 07K6088 Kassendisplay

  

Professional 30cm (12) IBM POS monitor 4820-2GB. With a very high-quality capacitive ELO touch screen via RS-232 (serial). Touchscreen cable, VGA cable, power adapter and power cable.

SVGA 800x600, IBM p/n: 07K6088, used, in excellent condition, without foot. On the back there are 4x screw-in options, possibly e. You can possibly make a base out of plexiglass, or attach it to the bar column, etc. Capacitive touchscreens (like the iPhone) are a touchscreen variant of the no pressure is required for operation. This is due to the fact that this is an electric field that is built up over four corners and has a uniform voltage. With a finger or a conductive object, this field is now changed and sensors can be used to detect where the contact is taking place. Capacitive touchscreens: Their design is very different from that of resistive monitors, although the two systems share similarities. As with the models mentioned above, this technology is also based on a touch-sensitive layer on the surface of the monitor. How a capacitive touchscreen worksHow a capacitive touchscreen works In this case, the glass surface of the monitor is coated with a conductive layer, usually made of indium tin oxide (ITO). In a very small thickness, this material is transparent. This layer is connected to electrodes located on the edges of the monitor. This creates a uniform electric field on the surface of the monitor.

Or to put it another way: The surface is evenly charged. When a finger approaches this electric field, some of the charge jumps onto the finger. This disturbance is then perceived by the control of the monitor.

In the first capacitive touchscreens, the ITO layer was attached to the outside. It therefore wore out quickly, which limited the life of the product. Today, the algorithms for touch detection are so advanced that a greater distance between the ITO layer and the finger is possible. The surface of the monitor now only consists of simple glass. So wear and tear is no longer an issue.

The main advantage of capacitive touchscreens lies in the much less reduced brightness of the monitor. The low thickness of the conductive layer ensures high transparency (over 90%). They also offer excellent resolution.

And the control module is particularly compact. However, they are still significantly more expensive than resistive touchscreens. Item condition: Used, is in good optical condition. In this case, the glass surface of the monitor is coated with a conductive layer, usually made of indium tin oxide (ITO). Today, the algorithms for touch detection are so advanced that a greater distance between the ITO layer and the fin.
